Abstract
The invention provides a method utilizing industrial waste to prepare a non-asbestos calcium silicate board. The method includes the following steps: (1) producing waste concrete paper bag sizing agent; (2) dosing: 6%-10% of the waste concrete paper bag sizing agent, 35%-45% of quartz tailing mineral powder, 2%-8% of calcium carbide slurry, 4%-10% of wollastonite powder, 1%-5% of mica powder, 15%-25% of concrete, 5%-10% of slaked lime powder, 5%-10% of sanding powder, and 0.05%-0.1% of poly-acetamide; (3) pulping; (4) after starching by a pulp flowing machine, producing by a board-making machine board, cutting by a cutting machine board, steaming by a still kettle, drying by a drying machine, grind edging by an edge grinding machine, and sanding by a sander, the non-asbestos calcium silicate board is obtained. Due to the fact that the waste concrete paper bags, the quartz tailing mineral powder, the calcium carbide slurry and the like are used for raw materials for preparing the non-asbestos calcium silicate board, the method utilizing industrial waste to prepare the non-asbestos calcium silicate board not only is beneficial for saving natural resources such as raw ore and wood, but also is beneficial for reducing pollution from the waste to environment. Besides, the prepared products are low in cost, safe, and environmental friendly.
Description
Technical field
The present invention relates to the preparing technical field of asbestos-free calcium silicate board, be specifically related to a kind of method of utilizing trade waste to prepare asbestos-free calcium silicate board.
Background technology
Calcium silicate board is a kind of common material of construction, is widely used in indoor partition, ceiling decoration etc.The preparation of traditional calcium silicate board is used a large amount of asbestos raw materials conventionally, and mainly there is following shortcoming in asbestos raw material: 1, tiny fibrous magnesium silicate can be suspended in air after discharging for a long time, human body sucks a certain amount of fibrous magnesium silicate can cause the diseases such as asbestosis, lung cancer, mesothelioma of pleura, peritoneal mesothelioma and gastrointestinal cancer, the health of harmful to human; 2, asbestos belong to Nonrenewable resources, and a large amount of uses are unfavorable for the protection of natural resources.
Along with socioeconomic development, people are also more and more higher to the environmental requirement of material of construction, and asbestos-free calcium silicate board will progressively substitute traditional calcium silicate board.At present, the existing bibliographical information of preparation method of asbestos-free calcium silicate board, for example publication number is that CN1884180A, denomination of invention are in the Chinese patent application of " a kind of asbestos-free calcium silicate board and preparation method thereof ", a kind of preparation method of asbestos-free calcium silicate board is disclosed, the raw material that the method is used comprises quartz sand, lime, wood fibre etc., and making step comprises plays paper pulp, batching, making beating, starching, making sheet, cutting, steam-cured, oven dry, edging, sanding etc.The weak point that the preparation method of existing these asbestos-free calcium silicate boards exists is: because needs use a large amount of former mineral substance and lignocellulose raw material; cause its production cost higher on the one hand, be unfavorable on the other hand the protection of the natural resources such as raw ore and timber.
Summary of the invention
Technical problem solved by the invention is the deficiency for above-mentioned existence, and a kind of method of utilizing the trade wastes such as waste cement paper bag, Quartz Tails powder, calcium carbide mud to prepare asbestos-free calcium silicate board is provided.
The technical solution adopted in the present invention is: utilize trade waste to prepare the method for asbestos-free calcium silicate board, comprise the following steps:
1. by waste cement paper bag pulping in pulping engine, filter cleaner, is then 35～40 ° of SR by disc refiner defibrination defibrination to beating degree, makes waste cement paper bag slurry;
2. following raw material by weight percentage being dropped into proportioning machine evenly prepares burden: waste cement paper bag slurry 6～10%, Quartz Tails powder 35～45%, calcium carbide mud 2～8%, wollastonite powder 4～10%, mica powder 1～5%, cement 15～25%, slaked lime powder 5～10%, sanding powder 5～10%, policapram 0.05～0.1%, be mixed with compound;
3. compound is dropped into hollander, add water and pull an oar, compound and water ratio is by weight percentage: compound 10～15%, water 85～90%;
4. after, drying machine drying steam-cured through slurry flowing machine starching, laminator making sheet, cutting machine cutting plate, autoclave, edge polisher edging, abrasive finishing machine abrasive finishing, make asbestos-free calcium silicate board.
Described step 2. be preferably: following raw material is by weight percentage dropped into proportioning machine and evenly prepares burden: waste cement paper bag slurry 8.1%, Quartz Tails powder 40.9%, calcium carbide mud 5%, wollastonite powder 6%, mica powder 2.22%, cement 23.9%, slaked lime powder 7%, sanding powder 6.8%, policapram 0.08%, be mixed with compound.
The invention has the beneficial effects as follows: 1, the present invention utilizes the complete instead of woody fiber of waste cement paper bag, utilizes Quartz Tails powder to substitute quartz sand completely, utilize industrial residue calcium carbide mud Substitute For Partial lime or slaked lime, can not only reduce the consumption of the former mineral substance such as lignocellulose raw material and quartz sand, lime, and make waste cement paper bag, Quartz Tails powder, calcium carbide mud the like waste obtain harmless application, be conducive to save the natural resources such as raw ore and timber, be conducive to again reduce the pollution of waste to ecotope; 2, the prepared calcium silicate board of the present invention does not contain asbestos, can not work the mischief to the health of human body, and be a kind of environmentally friendly machine; 3, the present invention, owing to adopting waste cement paper bag, Quartz Tails powder, calcium carbide mud the like waste as raw material, can reduce the production cost of product, improves enterprise competitiveness.
