Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ke motsoako o mosweu kapa o mosehla o bobebe, o se nang monko, o se nang chefo o nang le fibrous kapa phofo o lokisitsoeng ka ho etherifying ea alkaline cellulose le ethylene oxide (kapa chlorohydrin). Li-ether tsa cellulose tse qhibilihang tse seng tsa ionic. Hobane HEC e na le litšobotsi tse ntle tsa ho teteana, ho emisa, ho qhalakanya, ho kopanya, ho etsa filimi, ho sireletsa mongobo le ho fana ka li-colloid tse sireletsang, e sebelisitsoe haholo lipatlisisong tsa oli, ho koahela, kaho, meriana le lijo, masela, ho etsa pampiri le li-polymer. Polymerization le masimo a mang. Hydroxyethyl cellulose ha e tsitse mochesong o tloaelehileng le khatellong, e qoba mongobo, mocheso le mocheso o phahameng, 'me e na le ho qhibiliha ha letsoai ho hotle haholo bakeng sa dielectrics. Tharollo ea eona ea metsi e lumelloa ho ba le letsoai le phahameng 'me e tsitsitse.

Kena ka kotloloho tlhahisong

1. Kenya metsi a hloekileng ka baketeng e kholo e nang le blender e nang le sesepa se matla.

2. Qala ho hlohlelletsa ka ho tsoelang pele ka lebelo le tlase 'me butle-butle u sefe hydroxyethyl cellulose ka har'a tharollo ka ho lekana.

3. Tswela pele ho hlohlelletsa ho fihlela dikarolwana tsohle di kolobile ka hare.

4. Ebe o eketsa di-antifungal agents, di-alkaline adsorption tse kang di-pigment, di-dispersing helps, metsi a ammonia.

5. Hlohlelletsa ho fihlela hydroxyethyl cellulose eohle e qhibilihile ka botlalo (ho teteana ha tharollo ho eketseha haholo) pele o eketsa dikarolo tse ding foromong, mme o sila ho fihlela sehlahiswa se felile.

E na le joala ba 'mè

Mokhoa ona ke ho qala ka ho lokisa joala ba 'm'e ka bongata bo phahameng, ebe o bo eketsa penteng ea latex. Molemo oa mokhoa ona ke hore o na le ho tenyetseha ho hoholo 'me o ka eketsoa ka ho toba penteng e felileng, empa o lokela ho bolokoa hantle. Mehato e tšoana le mehato ea 1-4 mokhoeng oa 1, ntle le hore ho hlohlelletsa ho hoholo ha ho hlokahale hore ho qhibilihe ka botlalo hore e be tharollo e hlabang.

Ela hloko
Kaha hydroxyethyl cellulose e phekotsoeng holim'a metsi ke phofo kapa cellulose solid, ho bonolo ho e sebetsana le ho e qhibilihisa ka metsing ha feela lintlha tse latelang li hlokometsoe.

1. Pele le ka mora ho eketsa hydroxyethyl cellulose, e lokela ho hlohlelletsoa khafetsa ho fihlela tharollo e bonaletsa ka botlalo ebile e hlakile.

2. E lokela ho sefshoa ka har'a moqomo oa ho kopanya butle. U se ke ua eketsa ka ho toba hydroxyethyl cellulose e entsoeng likoto kapa libolo ka har'a moqomo oa ho kopanya ka bongata bo boholo kapa ka ho toba.

3. Thempereichara ea metsi le boleng ba pH ba metsi li na le kamano ea bohlokoa le ho qhibiliha ha hydroxyethyl cellulose, kahoo tlhokomelo e khethehileng e lokela ho lefshoa ho eona.

4. Le ka mohla u se ke ua eketsa lintho tse ling tsa alkaline motswakong pele phofo ea hydroxyethyl cellulose e futhumatsoa ke metsi. Ho phahamisa boleng ba PH ka mor'a ho futhumala ho thusa ho qhibiliha.

5. Ka hohle kamoo ho ka khonehang, eketsa sebolaya-fungus kapele kamoo ho ka khonehang.

6. Ha o sebedisa hydroxyethyl cellulose e nang le viscosity e phahameng, bongata ba jwala ba mme ha boa lokela ho feta 2.5-3%, ho seng jwalo jwala ba mme bo thata ho bo sebedisa. Hyxyethyl cellulose e phekotsweng kamora kalafo hangata ha e bonolo ho etsa dikotwana kapa di-sphere, mme e ke ke ya etsa di-colloid tse chitja tse sa qhibiliheng ka mora ho eketsa metsi.
