IHydroxypropyl methylcellulose (HPMC)yi-ether ye-cellulose engeyo-ionic eyenziwe kwi-cellulose ye-polymer yendalo yendalo ngokusebenzisa uchungechunge lwe-chemical processing. Azinavumba, azinancasa kwaye zingumgubo omhlophe ongenatyhefu odumba emanzini abandayo ukuya kwisisombululo se-colloidal esicacileyo okanye esimnyama kancinci. Ineempawu zokuqina, ukubopha, ukusabalalisa, i-emulsifying, ifilimu-ifom, ukumisa, i-adsorbing, i-gelling, i-surface properties, igcina umswakama kunye ne-colloids ekhuselayo. I-Hydroxypropyl methylcellulose, i-methylcellulose ingasetyenziselwa kwizinto zokwakha, i-coating industry, i-synthetic resin, i-ceramics industry, amayeza, ukutya, i-textile, ezolimo, iikhemikhali zemihla ngemihla kunye namanye amashishini.

②Ukuphucula ukuthambisa kunye neplastiki, kunye nokuphucula ukusebenza; udaka oluphuculwe yi-cellulose ether kulula ukwakha, lugcina ixesha lokwakha kunye nokunciphisa iindleko zokwakha.
③Ultra-high amanzi okugcina i-cellulose ether, ilungele izitena eziphezulu ezifunxa amanzi.
I-4 plate joint filler
① Ukugcinwa kwamanzi okugqwesileyo, ukwandisa ixesha lokuvula kunye nokuphucula ukusebenza kakuhle. I-lubricant ephezulu, kulula ukuyixuba.
②Ukuphucula ukuxhathisa kwe-shrinkage kunye nokumelana nokuqhekeka, kunye nokuphucula umgangatho womgangatho wengubo.
③Phucula ukunamathela komphezulu wokudibanisa kwaye unikeze ukuthungwa okugudileyo kunye nokugudileyo.
5 Izincamathelisi zeThayile
①Kulula ukomisa umxube wezithako, akukho maqhuma aya kuveliswa, isantya sesicelo siya kwandiswa, ukusebenza kokwakhiwa kuya kuphuculwa, ixesha lokusebenza liya kugcinwa, kwaye iindleko zokusebenza ziya kuncitshiswa.
②Ngokwandisa ixesha lokuvula, iphucula ukusebenza kakuhle kwethayili kwaye inika umphumo obalaseleyo wokubambelela.
6 Izixhobo zomgangatho ozimele
① Ibonelela nge-viscosity kwaye ingasetyenziswa njenge-anti-setting aid.
②Ukuphucula ukumpompa kwamanzi kunye nokuphucula ukusebenza kakuhle kwepaving.
③ Lawula ukugcinwa kwamanzi kunye nokushwabana ukunciphisa iintanda kunye nokushwabana komhlaba.
7 Ipeyinti esekwe emanzini
① Thintela imvula eqinileyo kwaye wandise ixesha lesikhongozeli semveliso. Uzinzo oluphezulu lwebhayoloji kunye nokuhambelana okugqwesileyo namanye amacandelo.
②Phucula ulwelo, ubonelele ngokumelana nokuchaphaza okulungileyo, ukuxhathisa kwe-sag kunye nomgangatho, kunye nokuqinisekisa ukugqitywa komphezulu ogqwesileyo.
8 umgubo wephepha lodonga
①Nyibilika ngokukhawuleza ngaphandle kwe-agglomeration, elungele ukuxutywa.
②Nikeza amandla ebhondi ephezulu.
9 Ibhodi yesamente eyongeziweyo
①Inokuncamathela okuphezulu kunye nokuthambisa, kwaye yongeza ukusetyenzwa kweemveliso ezikhutshiweyo.
②Ukuphucula amandla aluhlaza, ukukhuthaza ukumanzisa kunye nesiphumo sokunyanga, kunye nokuphucula isivuno.
Iimveliso ezili-10 ze-HPMC zodaka oluxutyiweyo olulungeleyo
IHPMCimveliso ngokukodwa esetyenziselwa udaka esele ixubene inokugcinwa kwamanzi okubhetele kuneemveliso eziqhelekileyo kudaka oluxubeneyo olulungeleyo, ukuqinisekisa ukuba i-inorganic cementitious material ifakwe ngokupheleleyo emanzini, kwaye ikhusela ngokuphawulekayo ukucuthwa kokuqina kwebhondi okubangelwa ukomisa ngokugqithisileyo kunye nokuqhekeka okubangelwa ukomisa ukushwabana.
