Ukusetshenziswa okuyinhloko nokwehluka kwe-hydroxypropyllllyrlose methylcellulose hpmc kanye ne-hydroxyethyl cellulose hec

Kukhona i-monosodium ye-monosodium yezimboni, i-carboxymethyl cellulose, i-hydroxypropyl methyl celtule, kanye ne-hydroxyyethyl cellulose, okuyinto esetshenziswa kakhulu. Phakathi kwezinhlobo ezintathu ze-cellulose, okunzima kakhulu ukuhlukanisa i-hydroxypropyllylyly methylcellulose kanye ne-hydroxyethyl cellulose. Masihlukanise lezi zinhlobo ezimbili ze-cellulose ngokusetshenziswa kwazo nemisebenzi.

Njenge-survic engekho, i-hydroxyethyl cellulose inezinto ezilandelayo ngokumisa, ukuqina, ukusabalalisa, ukugcwala, ukubopha amafilimu, ukugcinwa kwamanzi, ukugcinwa kwamanzi kanye nokuhlinzeka ngokuvikela ama-colloids:

1. I-HEC uqobo ngokwayo ayinalo-ionic futhi ingahlangana nebanga lamanye ama-polymers ancibilikayo amanzi, ama-surfactants, nosawoti. Kungumkhulu we-colloidal omkhulu omuhle kakhulu oqukethe izixazululo ze-electrolyte eziphakeme.

2. Uma uqhathanisa ne-methyl cellulose ye-methyl kanye ne-hydroxypropyl methyl celtule, amandla asabalalisayo ka-HEC yimbi kakhulu, kepha i-colloid evikelayo inekhono eliqine kakhulu.

I-3. Umthamo wokugcina amanzi uphakeme kabili njenge-methyl cellulose, futhi inomthethonqubo ongcono wokugeleza.

I-4. I-HEC incane emanzini ashisayo noma abandayo, futhi ayinqamuki ekushiseni okuphezulu noma ukubilisa, ngakho-ke inezinhlobonhlobo ze-soubity kanye ne-viscosity, kanye ne-gelation engeyona eye-thermal.

Ukusetshenziswa kwe-HEC: Ngokuvamile kusetshenziswa njengomenzeli wokuqina, i-ejenti evikelayo, ukunamathela, ukuqina kanye nokulungiselela i-emulsion, ijeli, amafutha, i-lotion, ukulungiswa kwamehlo.

Isingeniso sokwethulwa kwesicelo se-Hydroxypropyll (HPMC):

1 Imboni yezenhlamba: Njengomkhulu, i-distriant and stabilizer emkhakheni we-coating, inokuhambisana okuhle emanzini noma izixazululo ze-organic. njenge-remover yokupenda.

2. Ukukhiqiza i-Ceramic: Kusetshenziswe Kabanzi Njenge-Binder Ekwenziweni Kwemikhiqizo Ye-Ceramic.

3. Abanye: Lo mkhiqizo futhi usetshenziswa kabanzi ngesikhumba, imboni yomkhiqizo wephepha, ukulondolozwa kwezithelo kanye nokulondolozwa kwemifino kanye nemboni yezindwangu, njll.

4. Ukuphrinta kwe-Ink: Njengomkhulu, ukuhlakazeka kanye ne-stabilizer embonini ye-INK, kunokwenziwa okuhle emanzini noma izixazululo ze-organic.

I-5. Ipulasitiki: Isetshenziswa njenge-ejenti yokukhipha isikhunta, ithambile, i-lubricant, njll.

I-6. I-Polyvinyl Chloride: Isetshenziswa njenge-distrinsant ekukhiqizeni i-polyvinyl chloride, futhi i-ejenti ebalulekile yokulungiselela i-PVC ngokumiswa kwe-PVC ngokumiswa kwe-PVC ngokumiswa kwe-PVC ngokumiswa kwe-PVC ngokumiswa kwe-PVC ngokumiswa kwe-PVC ngokumiswa kwe-polymerization.

7. Imboni yezokwakha: Njengomenzeli wokugcina amanzi kanye ne-retarder yesihlabathi sesihlabathi sesihlabathi, kwenza ukuncipha kwesihlabathi. Kusetshenziswe njenge-binder ekunamathisweni kokulungiswa kokulungiswa, i-gypsum, i-putty powder noma ezinye izinto zokwakha ukuthuthukisa ukusakazeka kanye nesikhathi sokusebenza kwangaphambili. Isetshenziswa njenge-paste ye-ceramic tile, imabula, umhlobiso wepulasitiki, njengesithuthukisi sokunamathisela, futhi kunganciphisa futhi inani likasimende. Ukugcinwa kwamanzi kwe-HPMC kungavimba ama-slurry ekuqhekekeni ngenxa yokumiswa ngokushesha okukhulu ngemuva kwesicelo, futhi athuthukise amandla ngemuva kokuqina.
