Kuyiminerali ethambile ye-sulfate eyakhiwe nge-calcium sulfate dihydrate, okuthi, lapho ixutshwa namanzi, iqine ibe yinto eqinile futhi ehlala isikhathi eside.

Enye yezinto eziyinhloko ze-gypsum plaster yikhono layo lokumunca amanzi. Uma ixubene namanzi, i-gypsum plaster iqala ukuqina futhi ilaphe. Kodwa-ke, uma seselaphekile, i-gypsum plaster ayibhekwa njengengangeni manzi ngokuphelele.

Ukumelana Namanzi vs. Ukuxosha Amanzi

Kubalulekile ukuqaphela umehluko phakathi kokumelana namanzi nokuxosha amanzi. Ukumelana namanzi kusho ikhono lempahla lokukwazi ukumelana namanzi ngaphandle kokulimala noma ukuba buthakathaka. Ukuxosha amanzi kusho ikhono lempahla lokuxosha amanzi, livimbele ukuthi lingangeni phezulu.

I-Gypsum plaster ayibhekwa njengokumelana namanzi, njengoba ukuchayeka isikhathi eside emanzini noma kumswakama kungadala ukuthi iwohloke ngokuhamba kwesikhathi. Kodwa-ke, kungenziwa ukuthi kungabi namanzi amaningi ngokusebenzisa izithasiselo noma izimbotshana.

Izithasiselo kanye nama-Coatings

Izithasiselo ezihlukahlukene zingangezwa ku-gypsum plaster ukuze kwandiswe ukuxosha amanzi. Lezi zithasiselo zingabandakanya ama-agent okuvimbela amanzi, njenge-silicone, i-acrylic, noma i-polyurethane resins. Lawa ma-ejenti enza umgoqo ebusweni be-plaster, ukuvimbela amanzi ukuthi angangeni phezulu.

Enye inketho ukufaka i-coating ebusweni be-plaster. Izembatho zingafaka upende, i-varnish, noma i-epoxy, phakathi kwabanye. Lezi zembatho zakha umgoqo womzimba phezu kwe-plaster, okuvimbela amanzi ukuthi angangeni phezulu.

Izicelo ze-Water Gypsum Plaster

Kukhona izinhlelo zokusebenza lapho ukhonkolo lwe-gypsum olungangeni manzi lungadingeka. Isibonelo, ezindaweni lapho kukhona izinga eliphezulu lomswakama noma umswakama, njengezindlu zangasese noma amakhishi, i-gypsum plaster engangeni manzi ingase isetshenziselwe ukuvimbela umonakalo wamanzi. I-gypsum plaster engangeni manzi ingase isetshenziswe ezindaweni lapho kunobungozi bezikhukhula noma umonakalo wamanzi, njengezindlu zangaphansi noma izindawo zokukhasa.
