Umphumela we-hydroxypropyl methylcellulose kuzakhiwo zezinto zikakhonkolo!

IHydroxypropyl methylcellulose (HPMC) inezinto ezinhle kakhulu zokujiya futhi ingasetshenziswa njengesinqamuleli sokuhlakaza ukhonkolo.Esikhathini esedlule, le nto yayiwumkhiqizo wamakhemikhali owawushoda eShayina, futhi izindleko zawo zaziphezulu.Ngenxa yezizathu ezahlukahlukene, ukusetshenziswa kwayo embonini yezokwakha yezwe lami, eminyakeni yamuva nje, ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokufakelwa odongeni lwangaphandle, ukuntuleka kwenqubekelaphambili kubuchwepheshe bokukhiqiza i-cellulose, kanye nezici ezinhle kakhulu zothishanhloko kanye nentshisekelo ye-HPMC, i-HPMC. isetshenziswe kabanzi embonini yezokwakha.

Okukodwa: Ukuhlolwa kokulwa nokuhlakazwa:

Ukumelana nokuhlakazeka kuyinkomba ebalulekile yobuchwepheshe ukukala ikhwalithi yokuhlukaniswa.I-HPMC iyinhlanganisela ye-polymer encibilika emanzini, eyaziwa nangokuthi i-resin encibilika emanzini noma i-polymer encibilika emanzini.Yandisa ukuhlela kwengxube ngokwandisa i-viscosity ngamanzi.Kuyimpahla ye-polymer esekelwe emanzini engancibilika emanzini ukwenza izixazululo noma ukuhlakazeka.Ukuhlola kubonisa ukuthi lapho inani le-naphthalene-based high-efficiency reducers yamanzi likhuphuka, ukwengezwa kwezinciphisi zamanzi kuzonciphisa ukumelana nokuhlakazeka kukasimende osanda kuxutshwa.Lokhu kungenxa yokuthi isinciphisi samanzi esisebenza kahle kakhulu esisekelwe ku-naphthalene siyisisetshenziswa esenziwe nge-surfactant.Lapho isinciphisi samanzi sengezwa odongeni, isinciphisi samanzi siqondiswa ebusweni bezinhlayiya ze-samente ukuze ubuso bezinhlayiya ze-samente bube necala elifanayo.Lokhu kukhishwa kukagesi kwenza izinhlayiya ze-cement Isakhiwo se-flocculation esakhiwe sihlakazwa, futhi amanzi aqukethwe esakhiweni akhululwa, okuzobangela ukulahlekelwa ingxenye yesimenti.Ngesikhathi esifanayo, kutholakala ukuthi ngokwanda kokuqukethwe kwe-HPMC, ukumelana nokuhlakazeka kodaka olusanda kuxutshwa usimende kuba ngcono futhi kuba ngcono.

Okubili: izici zamandla zikakhonkolo:

(1) Ukwengezwa kwe-hydroxypropyl methylcellulose kunomphumela osobala wokunciphisa ingxube yodaka.Ngokukhuphuka kwenani le-HPMC, isikhathi sokuhlehlisa udaka sinwetshwa ngokulandelana.Ngaphansi kwenani elifanayo le-HPMC, ukubumba ngaphansi kwamanzi Isikhathi sokumisa udaka emoyeni side kunaleso esemoyeni, okuzuzisa ukupompa ukhonkolo osekelwe emanzini.

(2) Udaka lukasimende olusanda kuxutshwa oluxutshwe ne-hydroxypropyl methylcellulose lunezinto ezinhle zokuhlangana futhi cishe alukophi.

(3) Inani le-hydroxypropyl methylcellulose kanye nesidingo samanzi sodaka kwehle kuqala futhi kwakhuphuka ngokusobala.

(4) Ukufakwa kwe-ejenti yokunciphisa amanzi kuthuthukisa inkinga yokwanda kwesidingo samanzi sodaka, kodwa umthamo wawo kufanele ulawulwe ngendlela enengqondo, ngaphandle kwalokho ukungcola okungaphansi kwamanzi okunqanda ukuhlakazeka kodaka lukasimende olusanda kuxutshwa ngezinye izikhathi luzoncishiswa.

(5) Ukwengeza i-hydroxypropyl methylcellulose ngaphansi kwamanzi ingxube kakhonkolo engahlakazeki, ukulawula umthamo kunenzuzo emandleni.Ukuhlolwa kubonisa ukuthi isilinganiso samandla okhonkolo owenziwe ngamanzi kanye nokhonkolo owenziwe ngomoya ungama-84.8%, futhi umphumela uqhathaniswa kakhulu.
