K'hemik'hale ea letsatsi le letsatsi ea hydroxypropyl methyl cellulose

K'hemik'hale ea letsatsi le letsatsi ea hydroxypropyl methyl cellulose ke polymer ea maiketsetso e lokiselitsoeng ke phetoho ea lik'hemik'hale ea cellulose ea tlhaho joalo ka thepa e tala. Cellulose ether e tsoa ho selulose ea tlhaho, tlhahiso ea cellulose ether le polymer ea maiketsetso e fapane, thepa ea eona ea motheo ke cellulose, motsoako oa tlhaho oa polymer. Ka lebaka la sebopeho sa cellulose ea tlhaho, selulose ka boeona ha e na matla a ho sebetsana le li-etherifying agents. Leha ho le joalo, ka mor'a ho phekoloa ha moemeli oa ho ruruha, maqhama a matla a hydrogen pakeng le ka har'a liketane tsa limolek'hule li senyeha, 'me mosebetsi oa sehlopha sa hydroxyl o lokolloa ka selulose ea alkali e nang le bokhoni bo sebetsang. Kamora karabelo ea etherifying agent, sehlopha sa -OH se fetoloa -OR sehlopha ho fumana cellulose ether.

K'hemik'hale ea letsatsi le letsatsi e khethehileng ea 200 thousand viscosity instant instant hydroxypropyl methyl cellulose ke phofo e tšoeu kapa e mosehla hanyenyane, 'me ha e na monko, ha e na tatso, ha e na chefo. E qhibiliha ka motsoako oa metsi a batang le metsoako ea lintho tse phelang ho etsa tharollo e hlakileng ea viscous. Tharollo ea metsi e na le ts'ebetso ea holim'a metsi, pepeneneng e phahameng, botsitso bo matla, ho qhibiliha ka metsing ha ho amehe ke pH. Thickening le antifreeze e le hantle ka shampoo le ho hlatsoa 'mele, ho boloka metsi le sebopeho se setle sa filimi bakeng sa moriri le letlalo. Ka keketseho e khōlō ea thepa ea motheo e tala, cellulose (antifreeze thickener) e ka sebelisoa shampoong le ho hlatsoa ’mele ho ka fokotsa litšenyehelo haholo le ho finyella liphello tse lakatsehang.

1. Litšobotsi le melemo ea letsatsi le letsatsi ea lik'hemik'hale tsa cellulose HPMC:

1, ho teneha ho tlase, mocheso o phahameng le thobalano;

2, mefuta e mengata ea botsitso ba pH, ka boleng ba pH ba 3-11 e ka netefatsa botsitso ba eona;

3. Ho eketsa khatello ea maikutlo;

4. Eketsa bubble, tsitsisa bubble, ntlafatsa maikutlo a letlalo;

5. Ho ntlafatsa boleng ba tsamaiso ka katleho.

2 letsatsi le leng le le leng grade grade cellulose HPMC kopo ea kopo:

E sebelisoa ka shampoo, ho hlatsoa 'mele, ho hloekisa sefahleho, lotion, tranelate, gel, toner, conditioner, lihlahisoa tsa ho bōpa, sesepa sa meno, metsi, metsi a bubble ea ho bapala.

3 Karolo ea letsatsi le letsatsi ea selulose ea lik'hemik'hale tsa HPMC:

Tšebelisong ea litlolo, e sebelisoa haholo-holo bakeng sa ho teteka, ho foka, ho emulsification e tsitsitseng, ho hasana, ho khomarela, ho thehoa ha filimi le ntlafatso ea ts'ebetso ea ho boloka metsi, lihlahisoa tse phahameng tsa viscosity li sebelisoa e le ho teteaneng, lihlahisoa tse tlaase tsa viscosity li sebelisoa haholo-holo e le ho hasana ho emisoa le ho thehoa ha filimi. .

Theknoloji ea 4 ea letsatsi le letsatsi ea cellulose ea HPMC ea lik'hemik'hale:

Hydroxypropyl methyl fiber ho ikamahanya le viscosity ea indasteri ea lik'hemik'hale ke haholo-holo likete tse 100, tse likete tse 150, tse likete tse 200, ho ea ka mokhoa oa bona oa ho khetha palo ea ho eketsoa ka sehlahisoa hangata ke likete tse tharo ho isa ho tse hlano.
