Abstract
The invention discloses a method for preparing a gypsum board coagulation accelerator. The method comprises the following steps: (1) sieving gypsum powder in gypsum board edge-cutting wastes out; (2) jointly feeding the gypsum powder obtained in the step (1) and modified starch at a mass ratio of (3: 1)-(5: 1) into a ball mill, grinding and modifying the mixture by virtue of the ball mill to obtain a modified product, namely, the gypsum board coagulation accelerator. By utilizing gypsum powder in gypsum board edge-cutting wastes and carrying out starch coating modifying, the gypsum board coagulation accelerator is obtained so that the recycling of wastes is realized and the coagulation accelerator, which has the advantages of small particle size (up to 0.01mm or less), large surface area (more than 10000cm<2>/g), and good coagulation acceleration effect, is obtained, the usage of the coagulation accelerator is greatly reduced, the production cost is decreased, the quality of a product is improved and the corresponding problems when gypsum powder is used as a gypsum board coagulation accelerator are solved.
Description
Technical field
The present invention relates to a kind of preparation method of plaster tablets setting accelerator.
Background technology
In Thistle board is produced, sheet material edge produces trimming waste material after trimming sawing is cut, and the main component of trimming waste material is terra alba, plaster block and a scrap of paper, and wherein terra alba can use as the setting accelerator in board making process.
The calcining manners of desulfurated plaster is the calcining of steam indirect heat transfer, needs to add setting accelerator again to complete condensation in gypsum board manufacturing process.All the time, the setting accelerator of use is gypsum powder, and the granularity of gypsum powder is comparatively large, and generally at 0.01 ~ 0.02mm, specific surface area is less, is only 6000 ~ 7000cm
2about/g.Therefore, blood coagulation enhancing effect for making setting accelerator bring into normal play in Thistle board is produced, certainly will increase its add-on, this just causes water content in slip to increase, produce in the shortcoming such as energy consumption raising, production cost increase, plate property reduction.
Summary of the invention
Using gypsum powder to cause as plaster tablets setting accelerator the problem that production cost increases, plate property reduces for solving, the invention provides a kind of preparation method of plaster tablets setting accelerator, to prepare a kind of new plaster tablets setting accelerator, meeting need of production.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A preparation method for plaster tablets setting accelerator, comprises step:
(1) terra alba in plasterboard trimming waste material is sieved out;
(2) terra alba step (1) obtained and treated starch are sent in ball mill according to the ratio that mass ratio is 3:1 ~ 5:1 simultaneously and are ground, and the modifier through the modified acquisition of ball mill grinding is plaster tablets setting accelerator.
Preferably, the preparation method of above-mentioned plaster tablets setting accelerator also comprises step (3): the modifier of modified for ball mill grinding acquisition is transported to feed bin by reamer and stores for future use.
The present invention is by utilizing the terra alba in plasterboard trimming waste material and carrying out the modification of starch overlay film to it, obtain plaster tablets setting accelerator, both achieved the recycle of waste material, obtained again a kind of granularity little (can below 0.01mm be reached), specific surface area was large (more than 10000cm
2/ g), the setting accelerator of short solidifying better effects if, thus greatly reduce the use of setting accelerator, reduce production cost, improve quality product.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
The preparation method of the plaster tablets setting accelerator of the present embodiment, comprises step:
(1) terra alba in plasterboard trimming waste material is sieved out;
(2) terra alba step (1) obtained and treated starch are sent in ball mill according to the ratio that mass ratio is 3:1 ~ 5:1 simultaneously and are ground, and the modifier through the modified acquisition of ball mill grinding is plaster tablets setting accelerator.
Preferably, the preparation method of above-mentioned plaster tablets setting accelerator also comprises step (3): the modifier of modified for ball mill grinding acquisition is transported to feed bin by reamer and stores for future use.
The using method of the plaster tablets setting accelerator that the present invention prepares is: by spring measurement conveying reamer add weight percent be 0.3% ~ 1.8% to mixing reamer in fully mix with the plaster of Paris, play blood coagulation enhancing effect.
The present invention is by utilizing the terra alba in plasterboard trimming waste material and carrying out the modification of starch overlay film to it, obtain plaster tablets setting accelerator, both achieved the recycle of waste material, obtained again a kind of granularity little (can below 0.01mm be reached), specific surface area was large (more than 10000cm
2/ g), the setting accelerator of short solidifying better effects if, thus greatly reduce the use of setting accelerator, reduce production cost, improve quality product, solve the corresponding problem using gypsum powder to make plaster tablets setting accelerator to exist.
Above embodiments of the invention are explained in detail; but the present invention is not limited to above-described embodiment; in the ken that those of ordinary skill in the art possess, the various changes can also made under the prerequisite not departing from present inventive concept, also should be considered as protection scope of the present invention.
Claims (2)
1. a preparation method for plaster tablets setting accelerator, is characterized in that comprising the following steps:
(1) terra alba in plasterboard trimming waste material is sieved out;
