Hydroxyethyl cellulose (HEC) thepa le tšebeliso

Joalo ka motho ea se nang ionic,hydroxyethyl cellulose(HEC) e na le thepa e latelang ho kenyelletsa ho teteaneng, ho emisa, ho tlama, ho phalla, ho etsa filimi, ho qhalakanya, ho boloka metsi le ho fana ka li-colloid tse sireletsang:

1. HEC e qhibiliha ka metsing a chesang kapa a batang, 'me ha e chese ka mocheso o phahameng kapa ho belisoa, kahoo e na le mefuta e mengata ea ho qhibiliha le litšoaneleho tsa viscosity, le gelation e se nang mocheso;

2. The non-ionic ka boeona e ka ba hammoho le li-polymers tse ling tse qhibilihang ka metsing, li-surfactants le matsoai ka mefuta e mengata, 'me ke motsoako o babatsehang oa colloidal o nang le litharollo tse phahameng tsa electrolyte;

3. Matla a ho boloka metsi a phahame ka makhetlo a mabeli ho feta a methyl cellulose, 'me a na le taolo e ntle ea ho phalla.

4. Ha ho bapisoa le methyl cellulose e tsejoang le hydroxypropyl methyl cellulose, bokhoni ba ho qhalakanngoa ba HEC ke bo bobe ka ho fetisisa, empa matla a tšireletso a colloid a matla ka ho fetisisa.

Mokhoa oa ho sebelisa hydroxyethyl cellulose? 

1. Kena ka ho toba tlhahiso

1. Kenya metsi a hloekileng ka nkhong e kholo e nang le blender e phahameng ea ho kuta.

2. Qala ho sisinyeha ka ho tsoelang pele ka lebelo le tlaase 'me butle-butle sieve cellulose ea hydroxyethyl ka har'a tharollo ka mokhoa o ts'oanang.

3. Tsoela pele ho sisinya ho fihlela likaroloana tsohle li kolobisitsoe.

4. Ebe u eketsa moemeli oa tšireletso ea lehalima, li-additives tsa alkaline tse kang li-pigments, lithuso tsa ho qhalakanya, metsi a ammonia.

5. Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo) pele u eketsa likarolo tse ling ka foromo, 'me u sila ho fihlela e fetoha.
