Tšobotsi e ka sehloohong ea hydroxyethyl methylcellulose

Hydroxyethyl methylcellulose (HEMC) ke motsoako oa maiketsetso oa selulose o sebelisoang hangata lits'ebetsong tse fapaneng, joalo ka indastering ea lijo, ea meriana le ea tlhokomelo ea motho. Tse ling tsa litšobotsi tse ka sehloohong tsa HEMC li kenyelletsa ho qhibiliha ha metsi ho phahameng, bokhoni ba eona ba ho tiisa le ho tsitsisa tharollo, le ho lumellana ha eona le lisebelisoa tse ling.

E 'ngoe ea litšobotsi tse ka sehloohong tsa HEMC ke ho qhibiliha ha metsi ho phahameng. Sena se bolela hore e ka qhibiliha ka metsing habonolo, e lumella hore e kenyelelitsoe habonolo ho metsoako e kang emulsions, li-gel le li-suspensions. HEMC e boetse e sebelisana le mefuta e mengata ea lisebelisoa tse ling, e leng se etsang hore e be motsoako o ka sebelisoang lits'ebetsong tse ngata tse fapaneng.

Tšobotsi e 'ngoe ea bohlokoa ea HEMC ke bokhoni ba eona ba ho tiisa le ho tsitsisa tharollo. HEMC e na le viscosity e phahameng, e bolelang hore e ka eketsa botenya le 'mele ho tharollo. Sena se ka ba molemo ka ho khetheha lihlahisoa tse kang litlolo le litlolo, moo ho lakatsoang lesela le teteaneng, le boreleli. HEMC e ka boela ea thusa ho tsitsisa li-emulsions le li-suspensions, ho li thibela ho arohana ka nako.

HEMC e boetse e tsejoa ka thepa ea eona e babatsehang ea ho etsa lifilimi. Sena se bolela hore e ka etsa filimi e matla, e tenyetsehang holim'a thepa, e ka thusang ho e sireletsa ho senya kapa ho senyeha. Thepa ena e etsa HEMC motsoako o tsebahalang oa ho roala le lifilimi bakeng sa lits'ebetso tse fapaneng.

Ntle le thepa ena, HEMC e boetse e lumellana le lintho tse phelang ebile ha e na chefo, e leng se etsang hore e bolokehe bakeng sa ho sebelisoa lits'ebetsong tse ngata tse fapaneng. E boetse e hanyetsana le kholo ea likokoana-hloko, e thusang ho lelefatsa bophelo ba sethala sa lihlahisoa tse nang le HEMC.

Ka kakaretso, litšoaneleho tsa mantlha tsa hydroxyethyl methylcellulose li etsa hore e be motsoako o sebetsang ka bongata le o sebetsang bakeng sa lits'ebetso tse fapaneng. Ho qhibiliha ha metsi a mangata, bokhoni ba ho tiisa le ho tsitsisa litharollo, thepa ea ho etsa lifilimi, le ho lumellana le lisebelisoa tse ling ho etsa hore e be khetho e ratoang bakeng sa ho sebelisoa lihlahisoa tse fapa-fapaneng, ho tloha ho litlolo ho ea ho litlhare ho ea ho lihlahisoa tsa lijo.
