Gypsum retarder inobatsira kuchinjika kwekuvaka uye Kubudirira kwakasimba

Gypsum retarder chinhu chakakosha chekuvaka chinowedzera, chakagadzirirwa kuwedzera nguva yekugadzika yegypsum zvinhu, nekudaro kuvandudza kushanda kwekuvaka. Kemikari iyi inoshandiswa zvakanyanya muindasitiri yekuvaka, kunyanya mumapurojekiti anoda nguva yakareba yekuvaka, uye inoita basa rakakosha. Nekuda kweiyo ipfupi yekumisikidza nguva yechinyakare gypsum, inoganhura yakakura-yakakura uye yakaoma nzira yekuvaka, uye mushure mekuwedzera retarder, vashandi vanogona kuita nyore kuvaka kwakanaka uye kugadzirisa, kuve nechokwadi chekuvaka kwemhando uye kushanda nesimba.

Izvo zvakakosha zve gypsum retarder zvinogona kusanganisira zvakasiyana-siyana zve organic uye inorganic zvinhu, senge sodium citrate, tartaric acid uye zvichingodaro. Nekuita neyakanyungudika mugypsum, zvinhu izvi zvinononoka hydration reaction rate yegypsum, nekudaro kunonotsa yekutanga uye yekupedzisira coagulation nguva. Uku kunonoka hakukanganisi simba rekupedzisira repurasita, kuve nechokwadi chekugara uye kugadzikana kwechigadzirwa chakapedzwa.

Mumakore achangopfuura, nekuvandudzwa kwehunyanzvi hwekuvaka uye zviyero zvekuvaka, kudiwa kwegypsum retarder kuri kuramba kuchikura. Zvitsva zvakatipoteredza zvine hushamwari gypsum retardants zvishoma nezvishoma zvinofarirwa nemusika, uye vanoshandisa yakawanda yakasvibira uye yakagadzikana magadzirirwo kudzikisa kukanganisa kwakashata kwezvakatipoteredza. Vagadziri vari kutarisisa kusimudzira kwevanodzoresa zvakanaka uye nemamiriro ekunze kuti vasangane nebudiriro inodiwa yeindasitiri yekuvaka yemazuva ano.

Iko kushandiswa kwegypsum retarder kwakapamhama kwazvo, kusanganisa madziro plastering, sirin'i, yekushongedza modelling uye zvichingodaro. Inovimbisa kushanduka kwekushanda kwekuvaka pasina kukanganisa maitiro emuviri uye aesthetics yechigadzirwa chakapedzwa. Izvi zvinoita kuti makemikari ave chimwe chezvinhu zvakakosha mukuvaka kwemazuva ano.

Kazhinji, gypsum retarder sechinhu chekuwedzera chemakemikari yekuvandudza nyore kuvaka uye kushanda, kusimudzira kufambira mberi kwehunyanzvi hweindasitiri yekuvaka, uku ichitarisira maitiro ebudiriro yakadzikama, mukana wemusika weramangwana haugone kushoropodzwa.
