Hydroxypropyl Methyl Cellulose e Betse

Hydroxypropyl methylcellulose e sebelisoa e le lisebelisoa tse tala ho hlahisa oli, e ka phethelang ts'ebeliso ea tsoekere, ea ntlafatsa sekhahla sa ts'ebeliso ea lisebelisoa tse tala, ho fokotsa palo e setseng ea substrate ka har'a moro oa belisoa, ho fokotsa litšenyehelo tsa kalafo ea metsi a litšila, le ho etsa mokhoa oa sebopeho. ea hydroxypropyl methylcellulose e molemo E molemo bakeng sa ho ntlafatsa betch, batch le mekhoa e tsoelang pele ea ho belisoa, ho thibela ho qhekella ha mathata a amanang le setso le dilution;e boetse e na le molemo bakeng sa ho laola mekhoa ea ho belisa.

Hydroxypropyl methylcellulose, selulose e tala, e ka ba k'hothone e hloekisitsoeng, kapa e ka ba makhasi a lehong.E hloka ho siloa pele kapa nakong ea alkalization.Hoa hlokahala ho silafatsa thepa e tala ea selulose ka matla a mochini ho fokotsa tekanyo ea crystallinity le polymerization, ho eketsa sebaka sa eona sa holimo, ebe joale ho ntlafatsa tekanyo ea trihydroxyl le bokhoni ba karabelo ea lik'hemik'hale ea reactant ho selikalikoe sa tsoekere sa polymer ea cellulose.

Le hoja motsoako oa hydroxypropyl methylcellulose o sa rarahane, alkali, lisebelisoa tse tala lia silafatsoa le ho etsoa alkali.Etherification, solvent recovery, karohano ea centrifugal, ho hlatsoa le ho omisa libakeng tse fapa-fapaneng, empa ho kenyelletsa mahlale a mangata a bohlokoa le tsebo e ruileng ea litaba.Bakeng sa mefuta e fapaneng ea lihlahisoa, tikoloho ka 'ngoe e na le maemo a morao-rao a taolo, joalo ka mocheso, nako, khatello le taolo ea phallo lisebelisoa tse thusang le lisebelisoa tsa taolo ke tiisetso ea boleng bo tsitsitseng ba sehlahisoa, sistimi e tšepahalang ea tlhahiso, le e ntle.

Kaha ts'ebetso ea hydroxypropyl methylcellulose e tšoana le ea li-ethers tse ling tse qhibilihang ka metsing, e ka sebelisoa e le moemeli oa ho etsa filimi, thickener, emulsifier le stabilizer ka lipente tsa latex le lihlopha tsa ho roala ha resin e qhibilihang ka metsi, ho hanyetsa abrasion, ho roala ka mokhoa o ts'oanang. ho khomarela, le tsitsipano e ntlafetseng ea holim'a metsi, botsitso ho li-acids le metheo, le ho lumellana le li-pigments tsa tšepe.Hydroxypropyl methylcellulose e na le phello e ntle e le motenya bakeng sa lipente tse tšoeu tsa polyvinyl acetate.Tekanyo ea ho nkela sebaka sa cellulose ether e ntlafalitsoe, 'me ho hanyetsa libaktheria le hona ho ntlafatsoa.
