Onse hydroxypropyll methylcellulose ndi hydroxethyl cellulose ndi cellulose, pali kusiyana kotani pakati pa awiriwa?

Hydroxypropyl methylcellulose (hypromellose), imadziwikanso kuti hypromellose, ndi mtundu wa ma cellulose osakanizika a ether. Ndiosagwira, osagwira ntchito polymer omwe amagwiritsidwa ntchito ngati mafuta mu ophthalmology, kapena ngati premiprent kapena galimoto m'mankhwala am`kamwa.

Hydroxyethyl cellulose (ma c2h6o2) n, ndi chikasu chachikaso, chosawoneka bwino komanso cha kusinthika kwa cellulose yosungunuka. Chifukwa Hec ali ndi zinthu zabwino zokuterera, kuyimitsa, kubalalitsa, kuphatikizika, kulumikizana, kupanga chinyezi, kapangidwe kake katatu, 40%.

Ngakhale onse ndi cellouluse, pali kusiyana kwakukulu pakati pa awiriwa:

Hydroxypylpyl ndi hydroxyathylcellulose amasiyana mu katundu, kugwiritsa ntchito, ndi kusandulika.

1. Zosiyanasiyana

Hydroxypropyl methylcellulose (hpmc) ndi yoyera kapena yofananira kapena granlar ufa, kukhala wa cellulose yosiyanasiyana ya celluoni yosiyanasiyana. Ndiwosachita kupanga kosakhalako poikiro.

Hydroxyethycellulose (Hec) ndi yoyera kapena yachikaso, yopanda fungo komanso yosalala. Amasinthidwa ndi alkaline cellouse ndi ethylene oxide (kapena chlorohydrin). Ndi ya etherseby cellulose ether.

2. Kusungunuka ndikosiyana.

Hydroxypylpyl methylcelulose (pafupifupi influbleble mu mtheradi, ether ndi acetone. Zomveka kapena zomveka bwino za colloidal yosinthika yosungunuka m'madzi ozizira.

Hydroxyethyl cellulose: Ili ndi katundu wa kukula, kuyimitsa, kumanga, emulsifying, kufalikira ndi kuwononga. Zimatha kukonza njira m'matumbo osiyanasiyana m'madzi ndipo imakhala ndi kutentha kwa mchere wa electrolyte.

Hydroxypylpyl a methylcellulose ali ndi mawonekedwe a luso lakumwamba, kukana mchere pang'ono, kusungunuka kwamadzi, enzyme yopanga, kuphatikizika ndi kuphatikizika.

Pali zosiyana zambiri pakati pa awiriwa, ndipo kufunikira kwawo m'makampani kumakhala kosiyananso.

Hydroxypropyll methylclulose imagwiritsidwa ntchito kwambiri monga thicyner, wobalalitsa ndi okhazikika pamakampani okutira, ndipo amakhala ndi solumu bwino m'madzi kapena okhazikika. Mu makampani omanga, itha kugwiritsidwa ntchito mu simenti, gypsum, platx, pulasitala, ndi zina zowonjezera.

Hydroxyethyl cellulose imakhala ndi mphamvu yakukula, kuyimitsa, kumanga, emulsifying, kubalalitsa komanso kuwononga. Zimatha kukonza njira m'matumbo osiyanasiyana m'madzi ndipo imakhala ndi kutentha kwa mchere wa electrolyte. Hydroxyethyl cellulose ndi kanema wogwira mtima wakale, tockisier, Thicker, okhazikika mu shampoos, zotupa za tsitsi, zosalowerera, zolosera, zowunikira; Pa ufa wa ufa pakati ndi mtundu wa wothandizila wa dart. Ma hydroxyethyl cellulose amasungunuka mwachangu pamtunda wambiri, womwe ungafulumizitse kupanga ndikusintha luso. Chizindikiro chodziwikiratu chomwe chili ndi hydroxyethyl cellulose ndikuti zitha kusintha kusalala ndi kuphera kwa nsalu.

Hydroxyathyl cellulose itha kugwiritsidwanso ntchito pomanga zinthu zomanga monga konkriti, mavwende atsopano, matope ena, etc., kusunga madzi. Kuphatikiza pa kukonza madzi kusungirako madzi, hydroxethyl cellulose amathanso kuchepetsa kukonza ndikutseguka kwa Stucco kapena Mastic. Amachepetsa khungu, lokhazikika ndi kusaka. Izi zitha kuwongolera magwiridwe antchito, sinthani bwino ntchito, kupatula nthawi, ndipo nthawi yomweyo imakulitsa kuchuluka kwa kuchuluka kwa Stucco, motero kupulumutsa zida zopangira.
