Description
Technical field
The present invention relates to acidification, be specifically related to the Talcum after a kind of acidifying.
Background technology
Talcum is hydrothermal alteration mineral. Rich magnesium mineral often becomes Talcum through hydrothermal alteration, therefore Talcum is often the mineral illusions such as olivine, enstatite, hornblend, the tremolite. Talcum is a kind of common silicate mineral, and it is very soft and has satiny feel. Talcum is generally bulk, foliaceous, fibrous or radial, and color is white, canescence, and can because of the band shades of colour containing other impurity. The purposes of Talcum is a lot, as made refractory material, papermaking, the filler of rubber, pesticide absorbent, leather coating, cosmetic and engraving materials etc.
In order to improve Talcum application quality in the products such as Agricultural Materials, pesticide absorbent, leather coating, cosmetic, it is necessary to Talcum is carried out acidification.
Summary of the invention
It is an object of the invention to overcome weak point in prior art, it is provided that the Talcum after a kind of acidifying.
Talcum dispensing after acidifying is made up of Talcum, attapulgite clay, magnesium oxide, sulphuric acid, quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate.
The production method of the Talcum after acidifying: the Talcum dispensing after acidifying is inputted pulverizing in grinding machine, and the powder after pulverizing is the Talcum after acidifying.
Talcum is a kind of common silicate mineral, in irregular bulk, and white, yellow-white or pale blue Lycoperdon polymorphum Vitt, odorless, tasteless, there are wax sample gloss, the soft exquisiteness of matter, hands touches with lubricious sense, no hygroscopicity, puts and does not collapse scattered in water, and adiabatic and insulating properties strong, Pulvis Talci is conventional products on building materials market. The present invention selects the Pulvis Talci after pulverizing, talcous fineness of the particles��0.2 millimeter.
Attapulgite clay has the layer chain structure feature of uniqueness, and crystal is needle-like, fibrous or fiber collection shape. Attapulgite clay has the dispersion of uniqueness, good colloidal nature and the higher absorbability such as saline and alkaline high temperature resistant, anti-, and has certain plasticity and cohesive force, and the present invention selects fineness of the particles��5 millimeter of attapulgite clay.
Magnesium oxide has the general character of basic anhydride, belongs to Binder Materials, can improve the colloidal property of attapulgite clay.
Sulphuric acid selects concentration to be the concentrated sulphuric acid of 98%.
Quick dissolved sodium silicate is white powder material, can rapid solution in water, have that cohesive force is strong, intensity is higher, acid resistance, heat-resist, the feature of alkali resistance and poor water resistance.
Polyethenol series white solid, external form divide cotton-shaped, graininess, Powdered three kinds; Nonpoisonous and tasteless, graininess can be dissolved in 80--90 DEG C of water, pulverous other powders pre-dispersed after can dissolve at normal temperatures. There is good viscosity, polymerism, caking property and water-retaining property.
Hydroxypropyl methyl cellulose has thickening capabilities, salt discharge, pH stability, water-retaining property, dimensional stability, excellent film property and the feature such as resistance to enzyme, dispersibility and caking property widely.
Sodium carbonate has the general character and the heat stability of salt, soluble in water, and its aqueous solution, in alkalescence, is used for the Talcum pH value after adjusting acidifying in the present invention.
The technical scheme is that:
1, the Talcum dispensing after acidifying is made up of following component by weight percentage: Talcum semi-finished product 90��98% after acidifying, quick dissolved sodium silicate 0.1��5%, polyvinyl alcohol 0.1��5%, hydroxypropyl methyl cellulose 0.01��3% and sodium carbonate 0��3%.
2, the production method of the Talcum after acidifying: the Talcum dispensing after acidifying is inputted pulverizing in grinding machine, and fineness of the particles��0.074 millimeter, the powder after pulverizing is the Talcum finished product after acidifying.
3, the half-finished production method of Talcum after acidifying: stirring in the blender (1) first input of Talcum mixture operated, then dilute sulfuric acid is slowly added in Talcum mixture carry out acidification; (2), by the Talcum mixture after acidification, it is Talcum tablet, thickness��3 millimeter of Talcum tablet by twin rollers extruding; (3) Talcum tablet is transported to roasting in swinging drying oven, roasting time is 1��3 hour, and sintering temperature controls at 250��350 DEG C, Talcum tablet water content��5% after roasting, Talcum tablet after roasting is the Talcum semi-finished product after acidifying, and PCm is weight percentage.
4, the dispensing of Talcum tablet is made up of following component by weight percentage: Talcum mixture 75��95% and dilute sulfuric acid 5��25%.
5, the dispensing of Talcum mixture is made up of following component by weight percentage: Talcum 68��92%, attapulgite clay 7��30% and magnesium oxide 0.1��3%.
6, the dispensing of dilute sulfuric acid is made up of following component by weight percentage: concentration is concentrated sulphuric acid 1��25% and the water 75��99% of 98%, concentration be 98% concentrated sulphuric acid percentage ratio be weight percentage.
The production method of the Talcum after acidifying takes first acidifying to carry out compounding ingredient again, sulphuric acid and quick dissolved sodium silicate, polyvinyl alcohol, hydroxypropyl methyl cellulose and sodium carbonate generation chemical reaction can be avoided, give full play to raw-material respective characteristic in dispensing, and obtain complementation, it is ensured that the Talcum inherent quality after acidifying.
Needs according to product quality, the Talcum pH value after adopting sodium carbonate to adjust acidifying, method is simple.
After the acidified process of Talcum, pH value controls 5.5��7.5, it is possible to improve the utilization rate of Talcum, produces good economic benefit, environmental benefit and social benefit.
Talcum after acidifying has good thixotropy, heat stability, plasticity and close-burning feature.
Talcum after acidifying is applicable to produce the products such as Agricultural Materials, pesticide absorbent, leather coating, cosmetic.
