I-Hydroxypropyl methylcellulose endaweni eyomile ye-powder, ukungezwa kwe-cellulose ether kuphansi kakhulu, kodwa kungathuthukisa kakhulu ukusebenza kodaka olumanzi, futhi iyisengezo esiyinhloko esithinta ukusebenza kokwakhiwa kodaka.
IHydroxypropyl methylcellulose I-ether cellulose esetshenziswa odakeni lwempushana eyomile ikakhulukazi i-hydroxypropyl methylcellulose ether (HPMC).Kumakhekheba amasha oju lwezinyosi, kunganikeza ukuthambisa kokungenalutho.Embonini yokugqoka, ingasetshenziswa njenge-thickener, dispersant kanye ne-stabilizer embonini yokugqoka, futhi inokuhambisana okuhle emanzini noma ku-organic solvents.Njengesikhiphi sikapende.Ukuphrinta kukayinki: Isetshenziswa njenge-thickener, dispersant kanye ne-stabilizer embonini ye-inki, futhi inokuhambisana okuhle emanzini noma izincibilikisi zemvelo..Ipulasitiki: isetshenziswa njengokwakha i-ejenti yokukhululwa, isithambile, i-lubricant, njll. I-Polyvinyl chloride: Isetshenziswa njenge-dispersant ekukhiqizeni i-polyvinyl chloride, futhi iyi-ejenti eyinhloko eyisizayo yokulungiselela i-PVC ngokumiswa kwe-polymerization.IHydroxypropyl methylcellulose Okunye: Lo mkhiqizo futhi usetshenziswa kakhulu emikhiqizweni yesikhumba, yephepha, ekugcinweni kwezithelo nemifino kanye nezimboni zendwangu.
I-HPMC odakeni lwempushana eyomile ikakhulukazi idlala indima yokugcina amanzi, ukujiya kanye nokwenza ngcono ukusebenza kokwakhiwa.Ukugcinwa kwamanzi okuphezulu kodaka lokwakha kanye nesihlabathi sokuplasta kungawufaka amanzi ngokugcwele usimende futhi kwandise kakhulu amandla ebhondi.Ngasikhathi sinye, ingakhuphula ngokufanelekile amandla okuqina namandla okugunda, ithuthukise kakhulu umphumela wokwakha futhi ithuthukise ukusebenza kahle komsebenzi.Ukumelana namanzi nokunamafutha Ku-putty, i-hydroxypropyl methylcellulose cellulose ether ngokuyinhloko idlala indima yokugcina amanzi, isibopho kanye nokugcoba, ukugwema imifantu nokuphelelwa amanzi emzimbeni okubangelwa ukulahlekelwa kwamanzi amaningi, futhi ngesikhathi esifanayo ithuthukisa ukunamathela kwe-putty nokunciphisa ukwakhiwa. isikhathi.Isenzakalo sokuwohloka esimaphakathi senza ukwakhiwa kube bushelelezi.Phakathi kwemikhiqizo yochungechunge lwe-gypsum, i-hydroxypropyl methylcellulose cellulose ether ngokuyinhloko idlala indima yokugcina amanzi kanye nokugcoba, futhi ngesikhathi esifanayo inomphumela othile wokubuyisela emuva, oxazulula izinkinga zokuqhekeka kwemigqomo kanye nokuhluleka kokuqala kwamandla ngesikhathi sokwakhiwa., inganweba amahora okusebenza.I-agent ye-Hydroxypropyl methylcellulose interface isetshenziswa ngokuyinhloko njenge-thickener, engathuthukisa amandla aqinile namandla okugunda, ithuthukise ukumbozwa kwendawo, ithuthukise ukunamathela namandla okubopha.Izakhiwo: Lo mkhiqizo uyimpushana emhlophe noma ephuzi kancane, ayinaphunga, ayinambitheki futhi ayinabuthi.Ukugcinwa kwamanzi kanye namandla anda., i-putty powder noma ezinye izinto zokwakha njengesibopho sokuthuthukisa ukusabalala nokwandisa isikhathi sokusebenza.Ingasetshenziswa njenge-paste tile, imabula, umhlobiso wepulasitiki, ukuqinisa ukunamathisela, futhi inganciphisa inani likasimende.Ukusebenza kokugcina amanzi kwe-HPMC kuvimbela udaka ekuqhekekeni ngenxa yokoma ngokushesha ngemva kokufakwa, futhi kuthuthukisa amandla ngemva kokuqina.Ukwakhiwa kwe-Ceramic: Isetshenziswa kabanzi njengesibopho ekwenzeni imikhiqizo yobumba.Ukuzinza kwe-PH: I-viscosity yesisombululo esinamanzi salo mkhiqizo izinzile kububanzi obungu-PH3.0-11.0.Umphumela wokugcina amanzi: IHydroxypropyl methylcellulose i-hydrophilic futhi isixazululo sayo esinamanzi sibonakala kakhulu.IHydroxypropyl methylcellulose (HPMC) yengezwa odakeni, kugypsum, kupende, njll. ukuze kugcinwe ukugcinwa kwamanzi okuphezulu emkhiqizweni.Ukugcinwa komumo: Uma kuqhathaniswa namanye ama-polymers ancibilika emanzini, isixazululo samanzi salo mkhiqizo sinezici ezikhethekile ze-viscoelastic.Ukwengezwa kwayo kungathuthukisa ikhono lokuma-okungaguquki kwemikhiqizo ye-ceramic ekhishwe, njll.
I-Lubricity ye-hydroxypropyl methylcellulose (HPMC): Ukwengeza lo mkhiqizo kunganciphisa i-friction coefficient futhi kuthuthukise ukuthambisa kwemikhiqizo yobumba ekhishwe kanye nemikhiqizo kasimende.Izakhiwo zokwakha ifilimu: Lo mkhiqizo ungakhiqiza amashidi aqinile, aguquguqukayo, futhi asobala anowoyela omuhle kanye nokumelana ne-ester, ikakhulukazi ukugcinwa kwamanzi nokwakhiwa okuyingqayizivele kwe-hydroxypropyl methylcellulose (HPMC), i-hydroxypropyl methylcellulose Indawo eyenza ifilimu ye-cellulose phambili eChina.
