Imiphumela ye-HPMC ne-CMC ekusebenzeni kokhonkolo

I-Hydroxypropylm methylcellulose (HPMC) kanye ne-carboxymethyl celtulose (CMC) zombili izimpi ze-cellulose zisetshenziswa kakhulu njengezengezo ezithakeni zokhonkolo. Basebenza ngezinhloso ezahlukahlukene futhi bangaba nemiphumela ebalulekile ekusebenzeni kokhonkolo. Nansi imiphumela ye-HPMC ne-CMC ekusebenzeni kokhonkolo:

1. Ukugcinwa kwamanzi: Kokubili i-HPMC ne-CMC kusebenza ama-ejenti asebenza ngamanzi asebenzayo. Bathuthukisa ukusebenziseka nokuvumelana kokhonkolo omusha ngokubambezela ukuhwamuka kwamanzi ngesikhathi sokuhlelwa nokwelapha. Lokhu kugcinwa kwamanzi isikhathi eside kusiza ekuqinisekiseni i-hydration eyanele yezinhlayiya zensimbi, ukukhuthaza ukuthuthukiswa kwamandla okuphelele nokwehlisa ubungozi bokuqhekeka okuhlambalazayo.
2. Ukusebenza: I-HPMC ne-CMC isebenza njenge-Rheology Modifiers, ukuthuthukisa ukuzokwenza kanye nokugeleza kokuxubana kokhonkolo. Bathuthukisa ukuhlangana nokuhlangana kokuhlanganiswa, okwenza kube lula ukubeka, ukuhlanganisa nokuqeda. Lokhu kusebenza okuthuthukile kusiza ukuvela okungcono futhi kunciphisa amathuba okuba vele noma ama-deceneccomps kukhonkolo onzima.
3. I-Adhesion: I-HPMC ne-CMC Thuthukisa ukunamathela kokhonkolo kuya ezinhlotsheni ezahlukahlukene, kufaka phakathi ama-aggregates, ukuqinisa imicu kanye nezindawo zokwakha. Bathuthukisa amandla ebhondi phakathi kwezinto zokwakha i-cementionale kanye nama-aggregates, behlisa ubungozi bokuhlehlisa noma ukuhlukunyezwa. Lokhu kukhuphuka okunamandla kunomthelela ekunciphiseni okuphelele nokwethembeka kokhonkolo.
4. Ukufakwa komoya: I-HPMC ne-CMC kungasebenza njengama-ejenti okufaka umoya lapho kusetshenziswa ukuxubeka kokhonkolo. Basiza ukwethula ama-bubble amancane omoya ku-mix, okuthuthukisa ukumelana nokuqina kwe-freeze Ukufakwa komoya okufanele kungavimba ukulimala kusuka ku-Frost Heave nokukala ezimotweni ezibandayo.
5. Ukubeka isikhathi: I-HPMC ne-CMC kungathonya isikhathi sokuhlelwa kokhonkolo. Ngokubambezela ukusabela kuka-hydration ka usimende, banganwebeka izikhathi zokuqala nezigcina zokugcina, ukuhlinzeka isikhathi esithe xaxa sokubekwa, ukuhlanganiswa, nokuqeda. Kodwa-ke, umthamo owedlulele noma ukwakhiwa okuthile kungaholela ezikhathini zokubeka isikhathi eside, kudinga ukulungiswa ngokucophelela ukufeza izidingo zephrojekthi.
6. Ukumelana nokuqhekeka: I-HPMC ne-CMC kufaka isandla ekumelaneni kukakhonkolo okulukhuni ngokuthuthukisa ubumbano, i-decticity, kanye nobunzima. Basiza ekunciphiseni ukwakheka kokuqhekeka kwe-shrinkage futhi banciphise ukusakazwa kwemifantu ekhona, ikakhulukazi ezindaweni ezivinjelwe noma eziphezulu. Lokhu kuvuselelwa okuthuthukile kwenza ukuqina kokuqina nokusebenza kwezakhiwo zikakhonkolo.
7. Ukuvumelana: I-HPMC ne-CMC iyahambisana nobubanzi obuhlukahlukene bokhonkolo kanye nezithasiselo, okuvumela izinketho zokwakheka eziguquguqukayo. Zingasetshenziswa ngokuhambisana nezinye ama-admixtures ezifana nama-superplastifizer, ama-accelerator, ama-retaarders, kanye nezinto zokungezelela cemecractive ukufezekisa izinhloso ezithile zokusebenza ngenkathi ugcina ukuhambisana okuphelele nokuqina.

I-HPMC ne-CMC Dlala izindima ezibalulekile ekuthuthukiseni ukusebenza ngokhonkolo ngokuthuthukisa ukugcinwa kwamanzi, ukusebenziseka, ukunamathela, ukuhanjiswa komoya, ukumelana nokuqina. Izakhiwo zabo eziguquguqukayo zizenza izengezo ezibalulekile zokwenza kahle ukuxubana kokhonkolo nokuthola izici zokusebenza okufunayo kwezicelo ezahlukahlukene zokwakha.
