Mokhoa oa ho sebelisa hydroxypropyl methylcellulose le mokhoa oa ho lokisa tharollo

Mokhoa oa ho sebelisa hydroxypropyl methylcellulose:

Eketsa ka ho toba tlhahisong, mokhoa ona ke mokhoa o bonolo le o khutšoanyane ka ho fetisisa oa nako, mehato e tobileng ke e latelang:

1. Eketsa palo e itseng ea metsi a belang (lihlahisoa tsa hydroxyethyl cellulose li qhibiliha ka metsing a batang, e le hore u ka eketsa metsi a batang) ho sejana se phahameng se susumetsang khatello ea kelello;

2. Bulela ts'ebetso e tsosang le e tlaase, 'me butle-butle u siee sehlahisoa ka har'a setshelo se susumetsang;

3. Tsoela pele ho hlohlelletsa ho fihlela likaroloana tsohle li kolobisitsoe;

4. Eketsa metsi a batang a lekaneng 'me u tsoele pele ho hlohlelletsa ho fihlela sehlahisoa sohle se qhibiliha ka ho feletseng (ho pepeseha ha tharollo ho ntlafatsoa haholo)

5. Ebe u eketsa lisebelisoa tse ling ka foromo

Lintho tseo u lokelang ho li hopola ha u lokisetsa litharollo

(1) Lihlahisoa tse se nang phekolo ea holim'a metsi (ntle lehydroxyethyl cellulose) ha ea lokela ho qhibiliha ka ho toba metsing a batang

(2) E tlameha ho sefshoa butle-butle ka har'a sets'oants'o sa ho kopanya, u se ke ua kenya sehlahisoa se seholo ka ho toba ka har'a setshelo sa ho kopanya.

(3) Thempereichara le pH boleng ba metsi li na le kamano e totobetseng le ho qhibiliha ha sehlahisoa, kahoo tlhokomelo e khethehileng e lokela ho lefshoa.

(4) Pele phofo ea sehlahisoa e koloba, u se ke ua kenya lintho tse ling tsa alkaline motsoako, feela ka mor'a hore phofo ea sehlahisoa e kolobile, boleng ba ph bo ka eketseha, bo tla thusa ho qhibiliha.

(5) Eketsa pele moemeli oa anti-fungal ka hohle kamoo ho ka khonehang

(6) Ha u sebelisa lihlahisoa tse nang le li-viscosity tse phahameng, boima ba joala ba 'mè ha boa lokela ho feta 2.5% -3%, ho seng joalo joala ba' mè bo thata ho sebetsa.

(7) Lihlahisoa tse kileng tsa phekoloa hang-hang li ke ke tsa sebelisoa bakeng sa lijo kapa meriana
