Ndi zowonjezera zingati mu gypsum plaster?

Pali zowonjezera zowonjezera zomwe zingagwiritsidwe ntchito mu pulasitala ya gypsum, kuphatikizapo accelerators, retarders, plasticizers, air-entraining agents, ma bonding agents, ndi zoletsa madzi.

1. Accelerators: Accelerators amagwiritsidwa ntchito kufulumizitsa nthawi yoyika gypsum plaster. Ma accelerators ambiri amaphatikizapo calcium sulfate, calcium chloride, ndi sodium sulfate.

2. Ma retarders: Ma retarders amagwiritsidwa ntchito kuchepetsa nthawi yoyika pulasitala ya gypsum. Ma retarders wamba amaphatikizapo sodium silicate ndi cellulose ethers monga hydroxypropyl methyl cellulose,HPMC.

3. Plasticizers: Plasticizers amagwiritsidwa ntchito kuonjezera kugwira ntchito kwa gypsum plaster. Plasticizers wamba monga glycerin ndi polyethylene glycol.

4. Othandizira mpweya: Othandizira mpweya amagwiritsidwa ntchito kupititsa patsogolo kugwira ntchito ndi mphamvu ya gypsum plaster. Zothandizira mpweya wodziwika bwino ndi sodium lauryl sulfate ndi mowa wa polyvinyl.

5. Zopangira zomangira: Zopangira zomangira zimagwiritsidwa ntchito kupititsa patsogolo kumamatira kwa pulasitala ya gypsum kuzinthu zina. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo utomoni wa acrylic ndi polyvinyl acetate.

6. Zolepheretsa madzi: Zoletsa madzi zimagwiritsidwa ntchito kuchepetsa kuyamwa kwa madzi ndi gypsum plaster. Zomwe zimagwiritsidwa ntchito pamadzi zimaphatikizapo ma silicones ndi sera.

Kupangidwa kwa chowonjezera cha gypsum plaster kumatengera momwe zinthu ziliri komanso mawonekedwe omwe amafunidwa pamtengowo. Kupanga chowonjezera cha gypsum plaster kumatengeranso mtundu wa gypsum womwe ukugwiritsidwa ntchito, ntchito yomwe mukufuna, komanso mawonekedwe omwe mukufuna. Nthawi zambiri, zowonjezera za gypsum pulasitala zimapangidwa pophatikiza mitundu yosiyanasiyana ya gypsum, zowonjezera, ndi zosakaniza zina mosiyanasiyana.
