I-hydroxypropyl methylcellulose yeklasi yekhemikhali yemihla ngemihla yipolymer eyenziwe ngee-linters zekotoni ze-cellulose zendalo ngokuguqulwa kwe-etherification. I-Cellulose ether yi-derivative ye-cellulose yendalo. Ukuveliswa kwe-cellulose ether kwahlukile kwii-polymers zokwenziwa. Izinto zayo ezisisiseko yi-cellulose, i-compound ye-polymer yendalo. Ngenxa yobuchule besakhiwo se-cellulose yendalo, i-cellulose ngokwayo ayinakho ukusabela kunye nee-agents ze-etherification. Nangona kunjalo, emva konyango lwe-agent yokudumba, ii-hydrogen bonds ezinamandla phakathi kwee-chains ze-molecular kunye nee-chains ziyatshatyalaliswa, kwaye ukukhululwa okusebenzayo kweqela le-hydroxyl kuba yi-reactive alkali cellulose. Fumana i-cellulose ether.
I-hydroxypropyl methylcellulose ye-Daily chemical grade yipowder emhlophe okanye emthubi kancinci, kwaye ayinavumba, ayinancasa kwaye ayinatyhefu. Isinyibilikisi esinokusasazeka ngokukhawuleza emanzini abandayo kwaye sixutywe nezinto eziphilayo, kwaye sifikelele kwisimo esiphezulu kwimizuzu embalwa ukuze senze isisombululo esicacileyo esixineneyo. Ulwelo lwamanzi lunomsebenzi womphezulu, lubonakala kakhulu, luzinzile kakhulu, kwaye aluchaphazeleki yi-pH xa lunyibilikisiwe emanzini. Lunemiphumo yokutyeba kunye ne-antifreeze kwiishampu kunye neejeli zeshawa, kwaye lugcina amanzi kwaye luneempawu ezilungileyo zokwenza ifilimu kwiinwele kunye nolusu. Ngokunyuka okukhulu kwezinto ezisisiseko, i-cellulose (i-antifreeze thickener) esetyenziswa kwisepha yokuhlamba impahla, ishawa, ijeli yeshawa inokunciphisa kakhulu iindleko kwaye ifezekise umphumo ofunekayo.
Iimpawu kunye neenzuzo ze-HPMC yamanzi abandayo ekwi-intanethi ye-chemical grade HPMC:
1. Ukucaphuka okuphantsi, ubushushu obuphezulu kwaye akunabungozi;
2. Uzinzo olubanzi lwexabiso le-pH, olunokuqinisekisa uzinzo lwayo kuluhlu lwexabiso le-pH 3-11;
3. Ukuphucula imeko;
4. Yandisa igwebu, uzinzise igwebu, uphucule indlela oluvakala ngayo ulusu;
5. Ukuphucula ngokufanelekileyo ukutyibilika kwenkqubo.
6. Kulula ukuyisebenzisa, faka emanzini abandayo ukuze usasazeke ngokukhawuleza ngaphandle kokuqhekeka
Ububanzi bokusetyenziswa kwe-HPMC ye-chemical grade cellulose yemihla ngemihla:
Isetyenziswa kwisepha yokuhlamba impahla, kwishampu, ekuhlambeni umzimba, ekuhlambeni ubuso, kwiloshini, kwikhrimu, kwijeli, kwitoner, kwiconditioner, kwiimveliso zokuhombisa, kwi-toothpaste, kwi-mouthwash, nakwi-toy bubble water.
Indima ye-HPMC ye-cellulose ye-daily chemical grade:
Kwizicelo zobuhle, isetyenziswa kakhulu ekwenzeni ukuqina, ukwenza igwebu, ukuxuba okuzinzileyo, ukusasazwa, ukunamathela, ukuphucula iipropati zokwenza ifilimu kunye nokugcina amanzi kwizinto zobuhle, iimveliso ezinobungqindilili obuphezulu zisetyenziselwa ukwenza ukuqina, iimveliso ezinobungqindilili obuphantsi zisetyenziselwa ikakhulu ukusasazwa kwe-suspension kunye nokwenza ifilimu.
Iteknoloji ye-HPMC ye-cellulose yeklasi yekhemikhali yemihla ngemihla:
I-viscosity ye-hydroxypropyl methyl fiber efanelekileyo kwishishini leekhemikhali zemihla ngemihla yi-100,000, 150,000, kunye ne-200,000. Ngokuqhelekileyo, i-viscosity ephezulu isetyenziswa kakhulu, kwaye isiphumo sokutyeba sesona silungileyo. Ngokwefomula yakho, ubungakanani bokongeza kwimveliso ngokubanzi yi-1,000. 2 amacandelo ukuya kwi-4 amacandelo ngewaka.
Ukulumkela
I-hydroxypropyl methylcellulose ye-daily chemical grade engafanelekiyo ayibonakali kakuhle, ayibi namandla, ayinciphi emva kokugcinwa ixesha elide, kwaye ezinye iindawo zinokuba nomngundo. Ukuze kuthintelwe ukuna kwe-cellulose ngexesha lokusetyenziswa, kufuneka ixutywe ngaphambi kokuba ifane.
