Izicelo ze-HPMC kanye ne-HEMC kokuthi Izinto Zokwakha

I-HPMC kanye ne-HEMC ama-polymer amabili abalulekile asetshenziswe kabanzi ezintweni zokwakha.Badlala indima ebalulekile ekwenzeni ngcono ukusebenza kanye nekhwalithi yezinto zokwakha.Kulesi sihloko, sizokwethula izakhiwo kanye nokusetshenziswa kwe-HPMC kanye ne-HEMC ezintweni zokwakha.

I-HPMC, eyaziwa nangokuthi i-hydroxypropyl methylcellulose, iyi-ether ye-cellulose etholakala ku-pulp yokhuni nemicu kakotini.Kuyimpushana engenaphunga, enganambitheki, engenabuthi encibilika emanzini.I-HPMC inezindawo ezinhle kakhulu zokugcinwa kwamanzi, ukujiya kanye ne-emulsifying, okuyenza ibe isithasiselo esidumile ezintweni zokwakha.

Esinye sezicelo ezivame kakhulu ze-HPMC izinamatheliso zamathayela asekelwe kusimende.I-HPMC ingathuthukisa amandla ebhondi nokusebenza kokunamathelayo, futhi ingavimbela amathayela ukuthi angasheleli noma awe ngesikhathi sokufakwa.Ukwengeza, i-HPMC inganciphisa ukumuncwa kwamanzi kwamathayela, okubalulekile ukuqina nokuphila isikhathi eside kokufakwa kwamathayela.

I-HPMC isetshenziswa kabanzi kumakhompiyutha azilinganisa usimende.Izikhonkwane ezizilinganisa ngokwazo zisetshenziselwa ukukala izitezi zikakhonkolo ezingalingani, futhi i-HPMC ingathuthukisa ukugeleza kwesakhiwo kanye nezakhiwo zokulinganisa.I-HPMC iphinde ivimbele inhlanganisela yokuzilinganisa ukuthi yakhe imifantu kanye nokuncipha, okubalulekile kubuqotho besistimu yokubeka phansi.

Okunye ukusetshenziswa kwe-HPMC ukuhunyushwa okusekelwe kusimende namapulasi.I-HPMC ingathuthukisa ukunamathela nokusebenza kokhonkolo noma isituko, futhi ingathuthukisa ukusebenza okungangeni manzi.Lokhu kubalulekile ukuvikela imvilophu yokwakha nokuvimbela ukulimala komswakama.

I-HEMC, eyaziwa nangokuthi i-hydroxyethyl methylcellulose, enye i-cellulose ether esetshenziswa kakhulu ezintweni zokwakha.I-HEMC ifana ne-HPMC ngokusebenza nezinhlelo zokusebenza, kodwa inezinzuzo ezithile ezihlukile eziyenza ifanelekele izinhlelo zokusebenza ezithile.

Enye yezinzuzo eziyinhloko ze-HEMC yi-viscosity yayo ephezulu.Lokhu kuyenza ilungele ukusetshenziswa emajazini awugqinsi nopende ukuze kuthuthukiswe ukugeleza nokulingana.I-HEMC iphinde isetshenziswe kabanzi kuma-caulks nama-sealants, angathuthukisa ukumelana kwamanzi nokunamathela kwemikhiqizo.

I-HEMC ijwayele ukusetshenziswa ezintweni zokwakha ezisekelwe ku-gypsum njengezinhlanganisela ezihlangene kanye ne-stucco.I-HEMC ithuthukisa ukusebenza kanye nokunamathela kwezinhlanganisela ezihlangene futhi iphinde ivimbele ukushwabana nokuqhekeka.Ngaphezu kwalokho, i-HEMC ingathuthukisa ukumelana namanzi kanye nokumelana nokukhunta kwama-plasters, okubalulekile ekhwalithi yomoya yangaphakathi yezakhiwo.

Sengiphetha, i-HPMC ne-HEMC zingama-polymer amabili abalulekile anezicelo eziningi ezintweni zokwakha.Badlala indima ebalulekile ekwenzeni ngcono ukusebenza kanye nekhwalithi yezinto zokwakha futhi basize ekwakheni izakhiwo ezihlala isikhathi eside, ezisebenza kahle nezisimeme.Njengoba lezi zinto zokwakha ziqhubeka nokuthuthukiswa futhi zicwengisiswa, singalindela izixazululo zokwakha ezintsha nezithuthukile esikhathini esizayo.
