Zingaphi izongezo kwi-gypsum plaster?

Kukho iintlobo ngeentlobo zezongezo ezinokuthi zisetyenziswe kwi-gypsum plaster, kubandakanywa i-accelerators, i-retarders, i-plasticizers, i-air-entraining agents, i-bonding agents, kunye ne-repellents yamanzi.

1. I-Accelerators: I-Accelerators isetyenziselwa ukukhawuleza ixesha lokubeka i-gypsum plaster. Ii-accelerators eziqhelekileyo ziquka i-calcium sulfate, i-calcium chloride, kunye ne-sodium sulfate.

2. IiRetarders: IiRetarders zisetyenziselwa ukucothisa ixesha lokubeka i-gypsum plaster. Iiretarders eziqhelekileyo ziquka i-sodium silicate kunye ne-cellulose ethers ezifana ne-hydroxypropyl methyl cellulose, i-HPMC.

3. IiPlastiki: Iiplastiki zisetyenziselwa ukwandisa ukusebenza kwe-gypsum plaster. Iiplastiki eziqhelekileyo ziquka i-glycerin kunye ne-polyethylene glycol.

4. Ii-Agent-entraining agents: Ii-agent zokungenisa umoya zisetyenziselwa ukuphucula ukusebenza kunye namandla e-gypsum plaster. Ii-agent eziqhelekileyo zokungenisa umoya ziquka i-sodium lauryl sulfate kunye ne-polyvinyl alcohol.

5. Ii-agent zokubambisana: Ii-agent ezidibeneyo zisetyenziselwa ukuphucula ukunamathela kwe-gypsum plaster kwezinye izinto. Iiarhente ezixhaphakileyo zibandakanya i-acrylic resins kunye ne-polyvinyl acetate.

6. Izinto ezigxotha amanzi: Izinto ezigxotha amanzi zisetyenziselwa ukunciphisa ukufunxa kwamanzi nge-gypsum plaster. Izinto eziqhelekileyo zokugxotha amanzi ziquka i-silicones kunye ne-wax.

Ukuqulunqwa kwesongezo se-gypsum plaster kuya kuxhomekeka kwiipropati ezithile kunye neempawu ezifunwayo kwimveliso. Ukuqulunqwa kwesongezo se-gypsum plaster kuya kuxhomekeka kuhlobo lwe-gypsum esetyenziswayo, isicelo esifunwayo, kunye neempawu zokusebenza ezifunwayo. Ngokuqhelekileyo, izongezo ze-gypsum plaster zenziwe ngokudibanisa iintlobo ezahlukeneyo zegypsum, izongezo, kunye nezinye izithako ngomlinganiselo othile.
