A kind of fireproof heat insulating mortar production technique and production equipment
Technical field
The invention belongs to production technique and the production equipment of the energy-conservation commodity mortar of Building Fire Protection, particularly a kind of fireproof heat insulating mortar production technique and production equipment.
Background technology
Novel fire-resistance heat-insulation mortar is similar to inorganic light-weight aggregate thermal insulation mortar; all take cement as main gelling material; flyash, breeze etc. are adulterant; take glass bead, pearlstone, expanded vermiculite etc. is inorganic light-weight aggregate; mix high molecular polymer and other functional additives mix, there is good flame retardant resistance and thermal and insulating performance.
Produce at present the conventional production technique of Novel fire-resistance heat-insulation mortar and have following two kinds:
One, cement, flyash, light-weight aggregate (glass bead, pearlstone etc.) and additive are measured to rear disposable stirring by the requirement of processing compound; after mixing the time that reaches process stipulation, stop stirring; mortar product is sent into finished product bin, metering packing.The shortcoming of this technique is: 1. production efficiency is low, and the production cycle is longer, and compares labor intensive, and a plurality of links, by Artificial Control, have increased in production and produced wrong probability.2. the unit weight of inorganic light-weight aggregate and gelling material, adulterant and functional additive differs larger; mixing time that need to be longer just can stir; cause the fragmentation of light-weight aggregate (glass bead, pearlstone etc.); percentage of damage reaches more than 30%, and this has affected the thermal and insulating performance of product greatly.The tap density manufacturing a finished product is mixed finished product tap density with testing laboratory differs by more than 50kg/m
3.
Two, cement, flyash and functional additive etc. are stirred after by the requirement metering of processing compound, after mixing, send into finished product bin, mixed powder is carried out to metering packing; Again light-weight aggregate (glass bead, pearlstone etc.) is required to independent metering packing according to processing compound.According to certain ratio, both being added to water at the construction field (site) stirs into slurry and directly uses.The shortcoming of this technique is: 1. mixed powder and inorganic light-weight aggregate (glass bead, pearlstone) working-yard is carried out secondary stirring and be there will be slurry to stir inhomogeneous, the unsettled problem of stock quality.2. inorganic light-weight aggregate is frangible, and working-yard will obtain uniform slurry, must extend churning time, and this makes the fragmentation of light-weight aggregate more serious, the energy saving of larger reduction product.3. the existing country of this production technique conflicts mutually with industry standard specification.4. inorganic light-weight aggregate needs secondary measurement to use, and has increased expending of dust pollution and manpower, reduces production efficiency.
Summary of the invention
Technical problem to be solved by this invention be the not science of production technique for existing inorganic light-weight aggregate thermal insulation mortar, production equipment and the production efficiency that causes low, stir that percentage of damage inhomogeneous, inorganic light-weight aggregate is high, unstable product quality and the serious defect of dust pollution, thereby provide a kind of production efficiency high, stir and avoid light-weight aggregate fragmentation, steady quality, avoid production technique and the device of the science of dust pollution.
