Ibakala lemihla ngemihla lemichiza ye-hydroxypropyl methylcellulose yipolymer eyenziweyo eyenziwe kwi-cotton linters ye-cellulose yendalo ngokuguqulwa kwe-etherification.I-ether ye-cellulose iphuma kwi-cellulose yendalo.Ukuveliswa kwe-cellulose ether kuyahluka kwiipolymers zokwenziwa.Izinto zayo ezisisiseko ziyi-cellulose, i-polymer compound yendalo.Ngenxa yobungcali besakhiwo se-cellulose yendalo, i-cellulose ngokwayo ayinakho ukusabela kunye nee-etherification agents.Nangona kunjalo, emva kokunyangwa kwe-ejenti yokuvuvukala, iibhondi ze-hydrogen ezomeleleyo phakathi kwamatyathanga e-molecular kunye namatyathanga atshatyalaliswa, kwaye ukukhutshwa okusebenzayo kweqela le-hydroxyl kuba yi-alkali cellulose esebenzayo.Fumana i-cellulose ether.
Umgangatho wemichiza wemihla ngemihla i-hydroxypropyl methylcellulose ngumgubo omhlophe okanye omthubi kancinane, kwaye ayinavumba, ayinancasa kwaye ayinayo ityhefu.I-solvent enokuthi isasazwe ngokukhawuleza emanzini abandayo kwaye ixutywe kunye ne-organic matter, kwaye ifikelele kwisigxina esiphezulu kwimizuzu embalwa ukwenza isisombululo se-viscous esicacileyo.Ulwelo lwamanzi lunomsebenzi ongaphezulu, ukukhanya okuphezulu, ukuzinza okuqinileyo, kwaye akuchaphazeli i-pH xa inyibilika emanzini.Ineziphumo ezityebileyo kunye ne-antifreeze kwiishampu kunye neegels zeshawa, kwaye inokugcinwa kwamanzi kunye neempawu ezilungileyo zokwenza ifilimu yeenwele kunye nolusu.Ngokunyuka okubukhali kwezixhobo ezisisiseko, i-cellulose (i-antifreeze thickener) esetyenziswa kwi-detergent, ishampu, ijeli yeshawa inokunciphisa kakhulu iindleko kwaye ifezekise umphumo oyifunayo.
Iimpawu kunye nezinto eziluncedo kwibakala lemihla ngemihla lemichiza yamanzi abandayo eselulosi yeHPMC:
1. Ukucaphuka okuphantsi, ubushushu obuphezulu kunye ne-non-toxic;
2. Ukuzinza kwexabiso le-pH ebanzi, enokuqinisekisa ukuzinza kwayo kuluhlu lwexabiso le-pH 3-11;
3. Ukuphucula imeko;
4. Ukwandisa i-foam, ukuzinzisa i-foam, ukuphucula ukuvakalelwa kwesikhumba;
5. Ukuphucula ngokufanelekileyo ukuhamba kwamanzi kwisistim.
6. Kulula ukuyisebenzisa, faka emanzini abandayo ukuze usasaze ngokukhawuleza ngaphandle kwe-clumping
Umda wokusetyenziswa kwe-HPMC yomgangatho wekhemikhali yomgangatho weseli:
Isetyenziswa kwindawo yokuhlamba iimpahla, ishampoo, ukuhlamba umzimba, isicoci sobuso, i-lotion, i-cream, ijeli, i-toner, i-conditioner, iimveliso zesitayile, intlama yamazinyo, i-mouthwash, amanzi okudlala.
Indima yemihla ngemihla yomgangatho wemichiza yeselulosi yeHPMC:
Kwizinto zokuthambisa, isetyenziselwa ukutyeba, ugwebu, i-emulsification ezinzileyo, i-dispersion, i-adhesion, ukuphuculwa kokwenza ifilim kunye nokugcinwa kwamanzi kwiipropathi zokuthambisa, iimveliso ze-viscosity ephezulu zisetyenziselwa ukutyeba, iimveliso ezine-viscosity ephantsi zisetyenziselwa ukunqunyanyiswa. ukusasazeka kunye nokwenza ifilimu.
Itekhnoloji ye-HPMC yomgangatho wemichiza yemihla ngemihla:
I-viscosity ye-hydroxypropyl methyl fiber efanelekileyo kwishishini lemichiza yemihla ngemihla ubukhulu becala yi-100,000, 150,000, kunye ne-200,000.Ngokuqhelekileyo, i-viscosity ephezulu isetyenziswa kakhulu, kwaye umphumo wokuqina ungcono kakhulu.Ngokwefomula yakho, inani lokongezwa kwimveliso ngokubanzi li-1,000.Iingxenye ezi-2 ukuya kwi-4 kwiwaka ngalinye.
Ukulumkela
Ibanga lemihla ngemihla lemichiza engafanelekanga ye-hydroxypropyl methylcellulose ibonisa ukungafihli kakuhle, isiphumo esibi sokutyeba, ukubhitya emva kokugcinwa kwexesha elide, kwaye ezinye iindawo zisenokungunda.Ukuze ugweme imvula ye-cellulose ngexesha lokusetyenziswa, kufuneka ishukunyiswe ngaphambi kokuba ukuhambelana kuvele.sebenzisa.
