01. Umahluko phakathi kwe-hydroxypropyl methyl yobuxoki kunye nekhwalithi ephezulu ye-hydroxypropyl methyl
Ukubonakala: Isitashi esicocekileyo i-HPCM ibonakala i-homogeneous kakhulu, phakathi kwe-0.3 kunye ne-0.4 g / ml.I-Amylum ibophelela kwistatshi ukuze i-HPCM ibelulwelo kwaye ibe noxinzelelo oluncinci kunezikhuseli eziqhelekileyo.
Iimeko: isitashi esigcwele isitashi, i-hpm powder, ifayibha phantsi kwe-microscope okanye iglasi yokukhulisa, i-HPCM luhlobo lwesitatshi olunokulawula isitashi okanye isitashi kunye neelentile.
Ivumba: I-Hydroxypropyl methylcellulose ecocekileyo I-HPMC ayinakujoja i-ammonia, istatshi kunye notywala;i-chargerated hydroxypropyl methylcellulose I-HPMC inokujoja zonke iintlobo zevumba, nokuba ayinancasa, iya kuziva ibuthathaka i-Shen.
Isisombululo samanzi: ecocekileyo, i-HPMC methylcellulose demethoxypropyl brinzolamide isisombululo esinamanzi sicacile, izinga lokugcinwa kwamanzi alula ≥ 97%;idiluted hydrolyzed cellulose-diluted HPMC hydrolyzed cellulose is turbid more, ugcino lwamanzi alufikeleli kwi 80%.
02. Ukugcinwa kwe-methyl cellulose kwiqondo lokushisa eliphezulu luphawu olubalulekileyo lokumisela umgangatho we-methyl cellulose ether.Izinto ezifana nobushushu bomoya, ubushushu bomoya kunye nesantya somoya zichaphazela ukuguquguquka kwe-samente slurry kunye neemveliso zegypsum.Ke ngoko, ukongeza inani elifanayo leemveliso ze-HPMC kumaxesha ahlukeneyo onyaka, kukho umahluko othile kwimpumelelo yokonga amanzi.Kwinkqubo ethile yokusebenza, umphumo we-moisturizing serosa unokulungiswa ngokunciphisa inani le-HPMC elongezelelweyo.Umgangatho ophezulu we-hydroxypropyl methylcellulose HPMC inokusombulula ngokufanelekileyo ingxaki yokugcinwa kwamanzi obushushu obuphezulu.
Umgangatho ophezulu we-methyl cellulose unokusasazwa ngokulinganayo nangokufanelekileyo kwi-sement mortar kunye neemveliso zokutyabeka, ukwenza ifilimu eqinile, ekhutshwe ngokuthe ngcembe kwisiseko sesiseko kwaye ifake i-hydrophilic reaction kunye ne-inorganic curling materials, ngaloo ndlela iqinisekisa amandla kunye nokuqina.I-HPMC cellulose methyl propoxylate isemgangathweni kwaye iyunifomu, kunye neoksijini ye-ethyl bromide kunye namaqela e-propionic acid ecaleni kwetsheyini ye-cellulose ye-molecular iyunifomu, ephucula ukudityaniswa kwe-oksijini kunye ne-hydrogen kwi-athomu nganye engundoqo ye-hydroxyl kunye ne-ether Amanzi aphantsi anokuguqula amanzi asimahla amanzi onga ufele, ngaloo ndlela elawula ngokufanelekileyo ukuphuphuma kwamanzi, ukuvelisa ubushushu, kunye nokufuma okuphezulu okusekwe emanzini.
Ngenxa yokwakhiwa kobushushu obuphezulu ehlotyeni, ukuze kuphunyezwe umphumo wokonga amanzi, kuyimfuneko ukongeza iimveliso zeHPMC ezikumgangatho ophezulu ngokwefomula, kungenjalo kuya kubangela iingxaki ezinjengokomisa kakhulu, amandla aphantsi, ukuqhekeka, ukungenzi nto. ukothuka nokuyeka emsebenzini, kwaye kwandisa ubunzima bokwakha kubasebenzi.Ngelixa uthoba ubushushu, kuyenzeka ukunciphisa kancinci inani le-HPMC elongeziweyo kwaye ufumane isiphumo esifanayo sokugcina amanzi.
