ethula
Imikhiqizo ye-Gypsum isetshenziswa kakhulu embonini yezokwakha ngenxa yokumelana nomlilo okuhle kakhulu, ukufakwa komsindo kanye nezakhiwo zokushisa ezishisayo. Kodwa-ke, imikhiqizo ye-gypsum iyodwa ayikwazi ukuhlangabezana nazo zonke izidingo zezakhiwo zesimanje. Ngakho-ke, izilungisi ezifana ne-hydroxypropyl methylcellulose (HPMC) zengezwa emikhiqizweni ye-gypsum ukuze kuthuthukiswe ukusebenza kwazo, amandla, ukugcinwa kwamanzi nokuqina. Kulesi sihloko, sixoxa ngomthelela we-HPMC emikhiqizweni ye-gypsum.
Thuthukisa ukusebenza
I-HPMC ivamise ukusetshenziswa njenge-thickener noma i-defoamer ukuthuthukisa ukusebenza kwemikhiqizo ye-gypsum. Ukwengezwa kwe-HPMC kungathuthukisa izakhiwo zemishini yezinto ze-gypsum, kuthuthukise ukusebenza kahle, futhi ngaleyo ndlela kuthole ukusebenza kahle kokwakha okungcono. Ngaphezu kwalokho, i-HPMC ingakhuphula ukumelana ne-sag kwemikhiqizo ye-gypsum, iqinisekise ukuthi imikhiqizo ngeke igxumeke noma igxumeke phakathi nenqubo yokwakha.
Thuthukisa ukugcinwa kwamanzi
Uma imikhiqizo ye-gypsum ixubene namanzi, ijwayele ukomisa ngokushesha, okuthinta inqubo yokwelapha kanye nekhwalithi yokugcina yomkhiqizo. Ukuze kuthuthukiswe ukugcinwa kwamanzi kwemikhiqizo ye-gypsum, i-HPMC yengezwa njengesibophezelo. I-HPMC yenza ifilimu elincanyana ebusweni begypsum, elingagcina umswakama emkhiqizweni, likhuthaze inqubo ye-hydration, futhi lithuthukise amandla omkhiqizo wokugcina.
ukwandisa amandla
Ukwengezwa kwe-HPMC kungathuthukisa kakhulu amandla emikhiqizo ye-gypsum. I-HPMC yenza ifilimu encane ebusweni bezinhlayiya ze-gypsum, ezingagcwalisa izikhala phakathi kwezinhlayiya futhi ziqinise ukwakheka komkhiqizo. Ifilimu iphinde ikhulise amandla okubopha phakathi kwezinhlayiya ze-gypsum, okuholela kumkhiqizo onamandla amakhulu okucindezela, amandla okuguquguquka kanye nokumelana nomthelela.
ukuqina okungcono
Ukuqina komkhiqizo we-gypsum kubalulekile ekusebenzeni kwawo, ikakhulukazi ezindaweni ezinomswakama ophezulu noma ukuchayeka emanzini. Ukusetshenziswa kwe-HPMC kungakhuphula ukuqina kwemikhiqizo ye-gypsum ngokwenza ungqimba oluvikelayo ebusweni bomkhiqizo, ukuvimbela ukungena komswakama kanye nokwenza ngcono ukumelana nesimo sezulu nokuguga. I-HPMC iphinde yehlise amathuba okuqhekeka futhi yehlise nengozi ye-delamination.
nciphisa ukuncipha
Imikhiqizo ye-Gypsum ivame ukuncipha ngesikhathi sokwelashwa, okungabangela ukuqhekeka nokuguqulwa komkhiqizo. Ngokungeza i-HPMC emikhiqizweni ye-gypsum, ukushwabana komkhiqizo kungancishiswa kakhulu, kwenze umkhiqizo wokugcina ube bushelelezi futhi uzinze kakhudlwana. Ngaphezu kwalokho, kunganciphisa ukuvela kokukhubazeka kwesakhiwo.
Ekuphetheni
Kafushane, ukusetshenziswa kwe-hydroxypropylmethylcellulose (HPMC) njengesilungisi emikhiqizweni ye-gypsum kungathuthukisa kakhulu ukusebenza kwayo, amandla, ukugcinwa kwamanzi nokuqina. I-HPMC iyisengezo esihle kakhulu esingagcini nje ngokuthuthukisa izakhiwo zemishini yemikhiqizo ye-gypsum, kodwa futhi sisiza ukunweba impilo yabo yesevisi futhi sinciphise ingozi yokungqubuzana noma ukuqhekeka. Ngakho-ke, kuyinto ebalulekile embonini yezokwakha futhi ukusetshenziswa kwayo kuyanda.
