Gypsum powder enhancer

                                                         Gypsum powder enhancer

Gesso strengthening agent what are the strength of gypsum additive formula table:
(1) sodium humate 0.3 ~ 0.5%, and building materials fiber waste 10 ~ 12%, 7.2 15.7% of papermaking waste liquid. Preparation and application: the above preparation good aqueous solution, according to the water paste ratio 1:1. 25-1 to 1. The proportion of 45 add gypsum powder, liquid after classics agitate, PH value control between 7.5 ~ 8 as appropriate, the introduction of humic acid and its salt gypsum products than pure water modulation forming gypsum products flexural strength increased by 1.35 ~ 1.97 times, the compressive strength increased by 1.31 ~ 2.23 times.
(2) the borax 0.2%, water 98.8% and use: the borax solution in water solution, then press with the solution of water and gypsum ratio 1:1, the proportion of 4 ~ 1.6 add gypsum powder is then churned into arts and crafts, product surface smooth, hard, high strength, compared with pure water gypsum products, bending degrees increased by 1.9 times, the compressive strength increased by 1.74 times.
(3) (surface enhanced) in aqueous solution containing 1% of polyethylene oxide, impregnation has been produced good arts and crafts for 10 minutes, can make its surface hardness, good wear resistance high strength.
(4) (light weight, high strength foaming plaster crafts, weight ratio), 89-99% gypsum powder, rubber polymer latex 2.8, 0.5 5, starch surfactants 0.1 ~ 0.2. Water react with gypsum latex foaming agent amount of 0.1 ~ 0.2 configuration and use; Will add soluble in water, and then mixing gypsum powder production.
(5) (weight ratio) : gypsum, 100, 107 glue 15 ~ 20%, white latex 5%, water 80%. Preparation and use: the two rubber dissolved in the water, made of mix the glue solution, then the mixture with gypsum ratio, 1.3:1 ratio mixing plaster for production.
(6) : 30% floor glue, 107 glue 10%, water 60%. Preparation and use: mix two kinds of rubber mixing with water are adjusted glue solution, then according to the mixture and gypsum ratio of 1.4:1 deployment of plaster for production.
(7) : melamine resin - ethyl alcohol three commercially available solid powder melamine resin, October 25 water dissolved, add glycol in 3, combined cooling to 10 to 15 ℃, with half water gypsum, 100, mix after injection molding, demoulding after a night of place.
(8) : - cement limestone gypsum, limestone, cement: water = 80:15:5:8 0 mixing injection molding
(9) : cement available white cement, alumina cement, ordinary Portland cement. 5% of gypsum mixed traffic, mixing and then adding water mixing injection molding.
Commercially (10) : tanning water reducing agent, tanned jianshuiji 3, add water 100 mixed evenly into aqueous solution containing tanned sexual water reducing agent, gypsum, mixed aqueous solution = (1.6 ~ 1.8) : 1
