I-Gypsum retarder isiza ukuguquguquka kokwakhiwa kanye nentuthuko eqhubekayo

I-Gypsum retarder iyisengezo esibalulekile sokwakha, esiklanyelwe ukwandisa isikhathi sokumisa sezinto ze-gypsum, ngaleyo ndlela sithuthukise ukusebenza kokwakhiwa. Leli khemikhali lisetshenziswa kakhulu embonini yezokwakha, ikakhulukazi kumaphrojekthi adinga isikhathi eside sokwakha, futhi lidlala indima ebalulekile. Ngenxa yesikhathi esifushane sokusetha se-gypsum yendabuko, ikhawulela inqubo yokwakha enkulu futhi eyinkimbinkimbi, futhi ngemva kokwengezwa kwe-retarder, abasebenzi bangakwazi ukwenza kalula ukwakhiwa okuhle nokulungiswa, ukuqinisekisa ikhwalithi kanye nokusebenza kahle.

Izingxenye eziyinhloko ze-gypsum retarder zingabandakanya izinhlobonhlobo zezinto eziphilayo kanye ne-inorganic, njenge-sodium citrate, i-tartaric acid nokunye. Ngokusabela ngezingxenye ezincibilikisiwe ku-gypsum, lezi zinto zibambezela izinga lokusabela kwe-hydration ye-gypsum, ngaleyo ndlela kubambezeleka isikhathi sokuqala nesokugcina sokuhlangana. Lokhu kubambezeleka akuthinti amandla okugcina e-plaster, ukuqinisekisa ukuqina nokuzinza komkhiqizo ophelile.

Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe bokwakha namazinga wokwakha, isidingo se-gypsum retarder siyaqhubeka sikhula. Ama-retardants amasha e-gypsum anobungani bemvelo athandwa kancane kancane yimakethe, futhi asebenzisa ukwakheka okuluhlaza okwengeziwe nokusimeme ukunciphisa umthelela omubi endaweni ezungezile. Abakhiqizi bagxile ekuthuthukisweni kwezinqamuleli ezisebenza kahle nezingayingeni imvelo ukuze kuhlangatshezwane nezidingo zentuthuko esimeme zemboni yezokwakha yesimanje.

Ukusetshenziswa kwe-gypsum retarder kubanzi kakhulu, kufaka phakathi ukuplasta odongeni, uphahla, ukumodela kokuhlobisa nokunye. Iqinisekisa ukuguquguquka komsebenzi wokwakha ngaphandle kokuthinta izakhiwo ezibonakalayo kanye nobuhle bomkhiqizo ophelile. Lokhu kwenza ikhemikhali ibe enye yezinto ezibalulekile ekwakhiweni kwesimanje.

Ngokuvamile, i-gypsum retarder njengesengezo samakhemikhali sokuthuthukisa ukunethezeka nokusebenza kahle kokwakhiwa, ikhuthaze inqubekelaphambili yezobuchwepheshe yemboni yezokwakha, kuyilapho ibhekelela umkhuba wentuthuko esimeme, amandla emakethe yesikhathi esizayo awanakubukelwa phansi.
