Abstract
The invention discloses a gypsum foaming technique; and the gypsum foaming technique comprises the following implementing steps of: preparing a foaming agent for the future use; after mixing short fibers or fiber cloths and a gypsum powder, adding polyvinyl chloride resin to an obtained mixture; mixing the mixture and the polyvinyl chloride resin for the future use; and uniformly mixing the foaming agent and the mixture. The gypsum foaming technique disclosed by the technical scheme is simple, convenient and easy.
Description
Technical field
The present invention relates to chemical field, what be specifically related to is a kind of Foamed Gypsum technology.
Background technology
The plaster of paris generally be do not have leachy.Foaming technique is exactly the weight per unit area with the balanced plaster of paris of whipping agent, alleviates the purpose of weight to be able to use safely of unit surface.The plasterboard whipping agent is used for the Foamed Gypsum of Thistle board production process.When whipping agent and gypsum aquation, generate Intermolecular Forces hydrogen chain, produce sterically hindered, cause the crystal lattice of gypsum structure to lack limit, excite gypsum active, the formation of accelerating network shape gypsum skeleton, thus reach reinforced plasterboard intensity, reduce the plasterboard capacity, greatly save material, substantially improve the purpose of plasterboard physicals.Present plasterboard whipping agent on the market is of a great variety, successful, but the plasterboard intensity of producing is limited.
Summary of the invention
According to above-mentioned deficiency, the invention provides a kind of Foamed Gypsum technology.
For achieving the above object, technical scheme of the present invention is: a kind of Foamed Gypsum technology, and implementation step is:
1) the preparation whipping agent is for subsequent use;
2) with staple fibre or cloth with after terra alba mixes, add polyvinyl chloride (PVC) RESINS, remix, for subsequent use;
3) whipping agent is mixed with said mixture all and get final product.
Described whipping agent is the mixture of sulfuric acid or hydrochloric acid and water.
Described whipping agent is phosphoric acid.
By technique scheme, the invention has the beneficial effects as follows: the method has been avoided the use suds-stabilizing agent, and is simple and easy to do.
