01. Umehluko phakathi kwe-hydroxypropyl methyl mbumbulu kanye nekhwalithi ephezulu ye-hydroxypropyl methyl
Ukubukeka: Isitashi esimsulwa i-HPCM ibonakala ine-homogeneous kakhulu, phakathi kuka-0.3 no-0.4 g/ml.I-Amylum ibophezela kusitashi ukuze i-HPCM iwuketshezi futhi icindezeleke kancane kuneziqeda ubuthi ezivamile.
Izimo: isitashi esigcwele isitashi, i-hpm powder, ifayibha ngaphansi kwesibonakhulu noma ingilazi yokukhulisa, i-HPCM uhlobo lwesitashi olukwazi ukulawula isitashi noma isitashi namalentile.
Iphunga: I-hydroxypropyl methylcellulose ehlanzekile HPMC ayikwazi ukuhogela i-ammonia, isitashi notshwala;I-HCMC ingakwazi ukuhogela zonke izinhlobo zephunga, noma ingenambitheki, izozizwa ibuthakathaka i-Shen.
Isixazululo samanzi: okuhlanzekile, i-HPMC methylcellulose demethoxypropyl brinzolamide isixazululo samanzi sicacile, izinga lokugcinwa kwamanzi alula ≥ 97%;I-cellulose ehlanjululwe nge-hydrolyzed cellulose-diluted HPMC hydrolyzed cellulose ixubene kakhulu, izinga lokugcinwa kwamanzi alifinyeleli ku-80%.
02. Ukulondolozwa kwe-methyl cellulose ezingeni lokushisa eliphezulu kuyinkomba ebalulekile yokunquma ikhwalithi ye-methyl cellulose ether.Izinto ezifana nezinga lokushisa lomoya, izinga lokushisa lomoya kanye nesivinini somoya kuthinta ukuntengantenga kodaka lukasimende nemikhiqizo yegypsum.Ngakho-ke, ukungeza inani elifanayo lemikhiqizo ye-HPMC ngezinkathi ezahlukene zonyaka, kunomehluko othile ekusebenzeni kahle kokonga amanzi.Enqubweni ethile yokusebenza, umphumela we-serosa ethambisayo ungalungiswa ngokunciphisa inani le-HPMC elingeziwe.Ikhwalithi ephezulu ye-hydroxypropyl methylcellulose HPMC ingaxazulula ngempumelelo inkinga yokugcinwa kwamanzi okushisa okuphezulu.
Ikhwalithi ephezulu ye-methyl cellulose ingasatshalaliswa ngokulinganayo nangempumelelo ku-cement mortar kanye nemikhiqizo yokunamathisela, yakha ifilimu eqinile, ekhishwa kancane kancane kusukela kungqimba oluyisisekelo futhi yakha ukusabela kwe-hydrophilic ngezinto zokugoqa ezingaphili, ngaleyo ndlela iqinisekise amandla nokuqina.I-HPMC cellulose methyl propoxylate isezingeni futhi iyunifomu, futhi umoya-mpilo we-ethyl bromide namaqembu e-propionic acid eduze kweketango lamangqamuzana e-cellulose ufana, othuthukisa ukuhlangana komoya-mpilo ne-hydrogen kwe-athomu ngayinye eyisihluthulelo ye-hydroxyl ne-ether Amanzi aphansi angaguqula amanzi amahhala abe amanzi okonga isikhumba, ngaleyo ndlela alawule ngempumelelo ukuhwamuka kwamanzi, akhiqize ukushisa, kanye nomswakama ophezulu osuselwe emanzini.
Ngenxa yokwakhiwa kokushisa okuphezulu ehlobo, ukuze kuzuzwe umphumela wokonga amanzi, kuyadingeka ukwengeza imikhiqizo yekhwalithi ephezulu ye-HPMC ngokusho kwefomula, ngaphandle kwalokho kuzodala izinkinga ezifana nokomisa ngokweqile, amandla aphansi, ukuqhekeka, ukungenzi lutho. ukushaqeka nokuyeka, futhi andise nobunzima bokwakha kubasebenzi.Ngenkathi wehlisa izinga lokushisa, kungenzeka ukunciphisa kancane kancane inani le-HPMC elingeziwe futhi uthole umphumela ofanayo wokonga amanzi.
