Hydroxypropyl methy cellose ndi carboxymethyl cellulose sodium imatha kusakanikirana

Hydroxypyl methy cellose (hpmc) ndi carboxymethyl cellulose sodium (cmc) Omwe amagwiritsidwa ntchito kawiri kawiri m'mafakitale osiyanasiyana chifukwa cha zinthu zapadera komanso zogwira ntchito zawo. Pomwe onse ali ndi ma poizoni okhazikika pa cellulose, amasiyanasiyana kapangidwe kake ndi katundu, zomwe zimawapangitsa kuti azigwiritsa ntchito njira zosiyanasiyana. Komabe, nthawi zina, amatha kusakanikirana kuti akwaniritse mawonekedwe kapena kupititsa patsogolo zinthu zina zomaliza.

Hydroxypropyl methy cellose (hpmc), imadziwikanso kuti hypromellose, ndi ma cellulose ether echirose elmer cellulose. Amapangidwa kudzera mu zomwe alkali amatenga cellulose yokhala ndi ma propylene oxide ndi methyl chloride. HPMC imagwiritsidwa ntchito kwambiri pa mankhwala opangira mankhwala, zida zomanga, zinthu zina, komanso zodzola zake zabwino zopangidwa ndi mafinya. HPMC imapezeka m'makalasi osiyanasiyana ndi kuchuluka kwa mafayilo osiyanasiyana, omwe amalola kuti azigwiritsa ntchito ntchito zosiyanasiyana.

Kumbali inayo, carboxymethyl cellulose sodium (cmc) ndi cellulose yosungunuka yamadzi yochokera ku cellulose yopezeka ndi sodium hydroxide ndi chlorooceic asidi. CMC imadziwika chifukwa cha kuchuluka kwake kosungika, kuthekera kwakukulitsa, kagwiritsidwe ka kamafilimu, komanso kukhazikika m'mikhalidwe yosiyanasiyana ya pH. Imapeza mapulogalamu mu zakudya, mankhwala odzola, zodzoladzola, nsalu, ndi kupanga pepala chifukwa cha kusintha kwake komanso kusagwirizana.

Pomwe HPMC ndi CMC imagawana zinthu zina monga kusungunuka madzi ndikutha kupanga mafilimu, zimawonetsanso mawonekedwe omwe amawapangitsa kukhala oyenera pazofunsira. Mwachitsanzo, HPMC imakondedwa mu mankhwala opangira mankhwala monga mapiritsi ndi makapisozi chifukwa cha zomwe amagwiritsa ntchito komanso kuphatikizidwa ndi zopanga zam'madzi. Kumbali inayi, CMC imagwiritsidwa ntchito popanga zakudya zomwe zimakhala ndi msuzi, mavalidwe, ndi zinthu zophika ngati wothandizira wokulirapo komanso wokhazikika.

Ngakhale anali osiyana, hpmc ndi masentimita amatha kusakanikirana pamodzi pamapangidwe ena kuti akwaniritse zoopsa kapena kupititsa patsogolo zinthu zina. Kufanana kwa HPMC ndi CMC kumatengera zinthu zingapo monga kapangidwe kake, kulemera kwa ma celecular, digiri yazolowa m'malo omaliza. Akasakanikirana pamodzi, HPMC ndi CMC imatha kuwonetsa bwino kwambiri, kumanga, ndi katundu wopanga mafilimu poyerekeza kugwiritsa ntchito polymer okha.

Kugwiritsa ntchito kamodzi kofananira kwa HPMC ndi CMC kukukula kwa mankhwala osokoneza bongo a hydrogel. Ma hydrogels ndi magawo atatu okhala ndi mawonekedwe omwe amatha kuyanjana ndikusunga madzi ambiri, ndikuwapangitsa kukhala oyenera kugwiritsa ntchito mankhwala osokoneza bongo. Pophatikiza hpmc ndi cmc mu ma ratios oyenerera, ofufuza amatha kugwirizanitsa katundu wa magetsi monga momwe mungakhalire, mphamvu zamakina, ndi mankhwala osokoneza bongo kuti mukwaniritse zofunika kuchita.

Kugwiritsanso ntchito kusakaniza HPMC ndi CMC kukukonzekera utoto wochokera m'madzi ndi zokutira. HPMC ndi CMC nthawi zambiri zimagwiritsidwa ntchito ngati thinkrifrif ndi phheology osinthira ma penti-zozikidwa pamadzi kuti mugwiritse ntchito katundu wawo, monga kuphwanya mphamvu, komanso kukana. Posintha kuchuluka kwa HPMC ku CMC, mapangidwe apakompyuta amatha kukwaniritsa ma vinya omwe mukufuna ndi mawonekedwe a penti ndikusungabe kukhazikika kwake ndikugwirira ntchito pakapita nthawi.

Kuphatikiza pa mankhwala ndi zokutira, zosakanizika kwa hpmc ndi cmc zimagwiritsidwanso ntchito makampani ogulitsa zakudya kuti athandize kupanga mawonekedwewo, kukhazikika, komanso pakamwa pazinthu zosiyanasiyana. Mwachitsanzo, hpmc ndi cmc nthawi zambiri zimawonjezeredwa ndi matalala ndi ayisikilimu monga okhazikika kuti aletse gawo latseke ndikusintha mawa. M'zinthu zophika, hpmc ndi cmc zitha kugwiritsidwa ntchito ngati mtanda wowongolera ufa kuti athandize kuyendetsa nthaka ndikuwonjezera moyo wa alumali.

Pomwe hydroxypypyl methyl cellulose (hpmc) ndi carboxymethyl cellulose cellsulose ndi ma cellulose opangidwa ndi ma cell, amatha kusakanikirana mosiyanasiyana kuti akwaniritse zomwe zimapangitsa kuti zitheke. Kufanana kwa HPMC ndi CMC kumatengera zinthu zosiyanasiyana monga kapangidwe kake, kulemera kwa matope, komanso zofuna za chinthu chomaliza. Mwa kusankha mosamala kuchuluka kwa hpmc ndi cmc, zopanga zimatha kugwirizanitsa katundu wawo kuti akwaniritse zofunika pa mankhwala, zokutira, zakudya zina, ndi mafakitale ena.
