Description
Technical field
The present invention relates to the preparing technical field of multicellular glass, particularly relate to a kind of circulation preparation method of multicellular glass, relate to the circulation preparation method of the corrosion-resistant large-density foam glass of a kind of low-temperature high-strength in particular.
Background technology
Nearest Two decades years comes, and multicellular glass is the porous material that a kind of inside is full of countless small connection or sealed porosity, is mainly used as skin body heat insulating, corrosion-resistant pad material that petrochemical complex hides cold insulation, flue and pipeline deeply.Raw material mainly glass cullet and the industrial residue of current production multicellular glass, but these material chemical components are unstable, impure more, well can not control the performance of multicellular glass.The multicellular glass general strength adopting cullet to prepare as raw material is not high, and the multicellular glass air hole structure adopting flyash or other mineral to prepare is undesirable, and the stability of simultaneously filling a prescription and reliability are not high yet.Above-mentioned shortcoming causes foam glass product mostly can only be used for building thermal insulation material, can not meet the rigors of some particular surroundingss.Such as multicellular glass is used for Chimney in Fossil Power Plant inside lining anti-corrosive material, must have stronger erosion resistance, lower thermal expansivity, higher thermal-shock resistance, and higher physical strength etc.The multicellular glass being used as now anti-corrosion pad all can not reach its best service requirements.
In recent years, because organic insulation material thermal conductivity is low, the feature of easy construction, its market share accounts for more than 90%.But good times don't last long, the feature that organic insulation material is inflammable, make just to spread fast once the presence of fire intensity of a fire to be difficult to control, in Nanjing, the fire such as ring International Square, Harbin longitude and latitude 360 degree of Gemini mansions, the Olympic Sports Center, Jinan, attached cultural center, new address of Beijing CCTV is exactly this situation.The Ministry of Public Security, house and town and country construction portion lead to word [2009] No. 46 literary compositions with public affairs and have issued " covil construction outer heat preservation system and decoration of exterior wall fire prevention temporary provisions ", and wherein Article 2 specifies that covil construction heat insulating material for external employing combustionproperty is the material of A level.On this basis, The Ministry of Public Security of the People's Republic of China, MOPS disappears [2011] No. 65 with public affairs further and has issued the notice of " about further clear and definite covil construction heat insulating material for external fire supervision management relevant requirements ".So the demand of market to inorganic A level non-fire material improves greatly, a few class inorganic heat insulation materials such as rock wool, multicellular glass, foamed concrete are subject to extensive concern.But multicellular glass itself also also exists the shortcomings such as production line energy consumption is large, for this point, laboratory have developed cryogenic foam glass (patent of invention: " a kind of cryogenic foam glass material ").
Cryogenic foam glass and multicellular glass have a lot of similarity, the area of pore accounts for 80% ~ 90% of cumulative volume, pore size is 0.5 ~ 2mm, and be a kind of adiabatic heat-insulation of superior performance, fp light building material and finishing material, A level does not fire the same life-span with buildings.But cryogenic foam glass is also the same with other inorganic materials such as multicellular glass, there is fragility large, the shortcoming that Young's modulus is large.
The Young's modulus of multicellular glass is at about 1400MPa, but in Practical Project, the Young's modulus of heat insulating material for external surface of wall is the smaller the better.Under the weather condition that Xia Redong is cold, the destruction of thermal stress to body of wall can not be ignored.With Hangzhou for representing city, the temperature data of actual measurement is body of wall top temperature 50 DEG C, temperature difference per day 22 DEG C.Wall insulating sheet materials is in an affined environment, and the performance such as situation and the thermal expansion difference to some extent of being heated of body of wall layers of material, freely deformation can not occur, and produce thermal stress when withstand temp load.The relation that the thermal stress of the elastic stage that Tan Zhuo, Zhan Shulin etc. have probed into before the Young's modulus of materials for wall and wall crazing by the method for finite element analysis changes.The conclusion drawn is, under hot summer and warm winter area condition, the Young's modulus reducing materials for wall obviously can reduce the principle stress extreme value of body of wall dangerous position, reduce the bond stress between wall heat insulation material and decorative material, reduce the principle stress level of heat insulating material for external, be conducive to security and the weather resistance of outer wall heat preservation system.Therefore, be one of key factor determining its market competitiveness to inorganic heat insulation material toughness reinforcing.
[2011] No. 65 official document regulations that public affairs disappear: 1, covil construction heat insulating material for external is included in the examination & verification of construction project design for fire protection, fire control acceptance and extent of tests of putting on record.Before new standard is issued, execution as strict as possible " covil construction outer heat preservation system and decoration of exterior wall fire prevention temporary provisions " (public logical No. [2009] 46, word) Article 2 regulation, covil construction heat insulating material for external employing combustionproperty is the material of A level.2, the fire supervision management of covil construction heat insulating material for external is strengthened.On March 15th, 2011 rises, and the construction project design for fire protection examination & verification that various places accept and fire control acceptance declare project, answer the requirement of strict implement this notice.To project under construction, as architectural exterior insulation adopts inflammable, combustible matl, NGO competent departments concerned should be submitted to supervise construction unit to remove inflammable, flammable lagging material; To the construction project not yet gone into operation, architectural exterior insulation adopts inflammable, combustible matl, construction unit should be supervised to change design, select non-fire material, again report to a higher authorities for approval.
Therefore, inorganic heat preserving and heat insulation material has had greatly market, and does not also have now the inorganic heat preserving and heat insulation material of the marketization can replace organic heat-insulating lagging material.Current conventional inorganic heat preserving and insulating material can be divided three classes: a class is the constituent material of self heat insulation wall, as foamed concrete, foam geopolymer, gas concrete, diatomite product, heat-insulating calcium silicate product and multicellular glass etc.; One class is the inorganic heat preservation such as rock wool, glass wool fiber; One class is add the thermal insulation mortar of heat preserving aggregate.And the major advantage of inorganic heat preserving and heat insulation material is that fire protection flame retarding, deformation coefficient are little, anti-aging, long service life, eco-environmental prote are good, main drawback is that unit weight is comparatively large, compactness and workability poor, thermal and insulating performance is not as organic insulation material.Also have the inorganic heat preserving and heat insulation material of class large-scale application not yet, the advantages such as be exactly aerogel, it is low that it has thermal conductivity, and unit weight is little, but there is the shortcomings such as the high and bad mechanical strength of preparation cost.
Multicellular glass belongs to the ep-type material that nation-building cause " 12 " is widelyd popularize and applied, there is little, the anti-chemical burn into of density by a series of excellent properties such as the infringement of ant mouse, heat insulating, waterproof and dampproof, fire prevention, sound absorptions, the engineering materials as insulation cold insulation, sound absorption has been widely used in chemical industry, petrochemical industry, light industry, refrigeration, heating installation carries, builds the fields such as environmental protection.But the mechanical strength of multicellular glass is low, easily broken, fracture in processing handling process, and also its anti-folding, ultimate compression strength are all difficult to the requirement meeting building field light-weight high-strength material.Therefore, in order to improve the intensity of multicellular glass, crystallite foam glass enters our visual field.But the preparation technology of crystallite foam glass is very similar with the preparation technology of multicellular glass, but introduce nucleator and heat treated process, add its preparation cost.Produce crystallite foam glass at present, all by powder dress in a mold, mould heats together with powder (blowing temperature is substantially more than 800 DEG C) simultaneously.So except consuming a large amount of whipping agents and the energy, what also have mould loses cost.
In recent years, in Nanjing there is architectural exterior insulation material fire in ring International Square, Harbin longitude and latitude 360 degree of Gemini mansions, the Olympic Sports Center, Jinan, attached cultural center, Beijing CCTV new address, teacher apartment, Jiangzhou, Shanghai, Shenyang feudal dynasty ten thousand prosperous mansion etc. in succession, cause serious personal's injures and deaths and property damage, build inflammable flammable heat insulating material for external and become the new disaster hidden-trouble of a class, the fire caused thus is in the multiple impetus.The Ministry of Public Security, house and town and country construction portion lead to word [2009] No. 46 literary compositions with public affairs and have issued " covil construction outer heat preservation system and decoration of exterior wall fire prevention temporary provisions ", and wherein Article 2 specifies that covil construction heat insulating material for external employing combustionproperty is the material of A level.On this basis, The Ministry of Public Security of the People's Republic of China, MOPS disappears [2011] No. 65 with public affairs further and has issued the notice of " about further clear and definite covil construction heat insulating material for external fire supervision management relevant requirements ".Inorganic heat insulation material is rare in the market, and the inorganic heat insulation material that cost performance is high is rare especially.The organic insulation material reaching 90% when market share amount is in when stagnation looks around, as the external wall outer insulation inorganic materials reaching fire-protection rating A level---and multicellular glass and rock wool have but welcome unprecedented market good opportunity.From the beginning of this year, rock wool price to be soared to more than 200 yuan/square metre by 42 yuan/square meter.Nonetheless, still supply falls short of demand for the market requirement.Also in its widespread use, there is bottleneck problem in insulating foam glass.
Multicellular glass is also called sintered glass, the spilehole that its inside is full of countless opening or remains silent, and the area of pore accounts for 80% ~ 90% of cumulative volume, and pore size is 0.5 ~ 5mm, and what also have is little of several microns.It is a kind of thermal insulation (cold insulation) of superior performance, sound absorption, protection against the tide, fp light high-strength building material and finishing material, and A level does not fire the same life-span with buildings.But multicellular glass also has some distances from our market requirement.On the one hand, the blowing temperature of multicellular glass more than 800 DEG C, mould steel alloy, not only expensive, and through multiple high temp heating, loss is comparatively large, and some enterprises are cylinder iron mould, although price is low, can cause oxidation, scaling, distortion after heating, loss is more serious.The multicellular glass that blowing temperature is higher not only means that die cost is high, and also have high energy consumption, established technology cost is very high; On the other hand, the Young's modulus of multicellular glass is comparatively large, and considers various variation of stress, and in practical application engineering, the Young's modulus of lagging material should be the smaller the better.
How reducing blowing temperature and the Young's modulus of multicellular glass, is realize its key issue had overwhelming superiority under organic insulation material is in the fierce market competition that when stagnation is looked around, inorganic materials is emerged in large numbers like the mushrooms after rain.The molten state of general solid glass powder is generally more than 800 DEG C, and the blowing temperature that reduce multicellular glass separately must look for path the angle of synthesis technique.Compared with solid state reaction, colloid chemistry reaction will more easily be carried out, and only needs lower synthesis temperature.This is because being diffused in nanometer range of component in colloid chemistry reaction system, and during solid state reaction, diffusion of components is in micrometer range.Under the thinking pattern of dealing with problems of pinpointing the problems, raw-material problem is also readily solved.
Water-soluble silicate, being commonly called as is sodium silicate, this is because water glass can foam after being heated, its foaming has two kinds of situations: one is heat free water bubbling when liquid state, is similar to boiling; Two is sclerosis post-foamings, is generally caused by Bound moisture volatilization (can realize at 200 DEG C ~ 300 DEG C temperature) after sclerosis, can prepares the material that porosity is very high.The water glass not adding other material modifications is carried out foam or free foaming and the porous material chemical stability extreme difference obtained, and pore structure also exists the defects such as bubble diameter heterogeneity, skewness.
In addition, in prior art, application number is: 200810063163, discloses a kind of cycle production process of multicellular glass, exists and does not possess and operate large-density foam glass, and the defect such as its unstable product quality; Application number is 200710019008, requires lower, cannot realize high-strength corrosion-resisting performance, and material choice is confined to the defects such as large density material to related process parameters to the intensity of product and corrosion resistance nature.
Production technique domestic at present, all adopt non-mold release agent to add a cover foaming, the diaphragm capsule dismounting demoulding, the preparation of admixtion adopts intermittent ball mill, manually unload powder, manual weighing adds powder, manually scrape powder, a dead lift pushes into kiln, temperature is high, labour intensity is large, dust from flying, have a strong impact on work and all round surrounding environment, the physical and mental health of workman is caused serious injury, handwork, error is large, production efficiency is low, product performance are poor and unstable, kiln is tunnel kiln, based on electrically heated, firing temperature is low, non-uniform temperature, production capacity is low, the maximum production line of current domestic production capacity only single line produces 10000 cubic metres per year, vibration air exhaust is not adopted in production technique, the techniques such as grid pressurization, product performance: unit weight, heat conduction, resistance to compression, water-intake rate, rupture modulus, the corrosion-resistant grade of low-temperature high-strength and stability and international product also have certain gap.
