izindaba

IHydroxypropyl methyl cellulose (HPMC) yenziwe ngokotini ocolisisiwe ocijile, owenziwe nge-alkali ngesisombululo se-sodium hydroxide (i-liquid caustic soda), efakwe i-methyl chloride ne-propylene oxide, bese ingathathi hlangothi, etholakala ngemva kokuhlunga, ukomiswa, ukuchotshozwa nokusefa.

Lo mkhiqizo uyibanga lezimboni i-HPMC, esetshenziswa kakhulu njenge-ejenti ehlakazayo yokukhiqizwa kwe-PVC kanyenjengomsizi oyinhloko osetshenziswa ekukhiqizeni i-PVC ukumiswa kwe-polymerization, iphinde isetshenziswe njenge-thickener,i-stabilizer, i-emulsifier, i-excipient, i-ejenti yokugcina amanzi, ne-ejenti yokwakha ifilimu njll. ekukhiqizeniamakhemikhali kaphethiloli, izinto zokwakha, okokususa upende, amakhemikhali ezolimo, oyinki,

izindwangu,i-ceramics,iphepha, izimonyo neminye imikhiqizo.Ngokuya isicelo in zokwenziwa resin, kungenzaimikhiqizo exegayo enezinhlayiya ezivamile, amandla adonsela phansi afanele kanye nezakhiwo ezinhle zokucubungula,ecishe ithathe indawo ye-gelatin kanye ne-polyvinyl alcohol njenge-dispersant.Okunye ukusetshenziswa kusezimbonini zenqubo yokwakha, ikakhulukazi ezokwakha ngemishini njengezindonga zokwakha,ukuhlanza kanye nokuvuvukala;ngamandla amakhulu okunamathela, kunganciphisa nomthamo usimende, ikakhulukazi ekwakhiweni kokuhlobisaukunamathisela amathayela, imabula kanye nokunquma kwepulasitiki. Uma isetshenziswa njenge-thickener embonini yokumboza,yenza ukunamathela kucwebezele futhi kuntekenteke, vikela amandla ukuthi angaqedi, futhi uthuthukise izakhiwo zokulinganisa.Uma isetshenziselwa ukhonkolo odongeni, i-gypsum paste, i-caulking gypsum, ne-putty engangeni manzi, ukugcinwa kwayo kwamanzifuthi amandla okubopha azothuthukiswa kakhulu.Ngaphezu kwalokho, angasetshenziswa nasezindaweni ezifana nalezii-ceramics esebenzayo, i-metallurgy, i-seed coating agents, oyinki abasekelwe emanzini, izimonyo, i-electronics, ukuphrintakanye nokudaya, iphepha njll.

Ngesikhathi sokulungiswa kwamasistimu efomula ahlukahlukene alo mkhiqizo, ithimba lezobuchwepheshe le-Taixu lingahlinzeka ngokubonisana kwezobuchwepheshe, ukulandelela kobuchwepheshe kanye nokwenza kahle kwesikhathi eside kwesistimu yefomula.
