Chofunika
Kufotokozera:Hydroxypropyl methyl cellulose is a propylene glycol ether of methylcellulose in which both hydroxypropyl and methyl groups are bound to the anhydrous glucose ring of cellulose by ether linkages. Hydroxypropyl mealose celluse imapangidwa kuchokera ku methyl cellulose pogwiritsa ntchito alkali ndi ma propylene oxide. Zotsatira zake ndi zosungunulira zamadzi zosungunuka za cellulose zomwe zimakhala ndi mitundu yonse ya methoxy ndi hydroxypyl. Mlingo wazolowa ndi 1.08 mpaka 1.83 ndi magulu a hydroxypyl monga gawo laling'ono. Yoyera mpaka yoyera-oyera ufa kapena granules. Sungunuka m'madzi ndi ena osungunuka. Zosatheka ku Mounol, yankho la madzimatul limakhala ndi ntchito yocheperako, ndikupanga filimu yopyapyala atayanika, ndipo imasinthasintha kuchokera ku Sol kupita ku gel osakira ndikutentha.
Gwiritsani Ntchito:Hydroxypylropyl ndi chingamu chomwe chimapangidwa ndi zomwe zimapangitsa kuti ma bulodi oxide ndi methyl chloride ndi alkali cellolise. Idzagwedezeka ngati kutentha kumachulukitsa potentha komanso pozizira kumadza. Kutentha kwa gel kumayambira kuyambira 60 ° C mpaka 90 ° C, ndikupanga zopindika ku Msushy gels. Amagwiritsidwa ntchito m'malo ophika mkate, zovala, zakudya zophika, ndi saladi kuvala zosakaniza za syneresis, kapangidwe kake, komanso kupereka mamasukiro otentha. Milingo yogwiritsa ntchito kuchokera ku 0,05 mpaka 1.0%.
Indications:Hydroxypypyl methylcellulose ndi gulu la mankhwalawa omwe amadziwika kuti ndi misozi yopanda zojambula. Amagwiritsidwa ntchito kuti athetseuma komanso kukwiya chifukwa cha kuchepa kwa misozi. Zimathandiza kupewa kuwonongeka kwa diso pamatenda ena. Hydroxypropyl methylcellulose imatha kugwiritsidwanso ntchito kuwononga magalasi olimba ndi maso owoneka. Kuphatikiza apo, itha kugwiritsidwa ntchito m'maso ena.
Mawu owonjezera
Hydroxypropyl methyl cellulose (hpmc)ndi wochokera ku cellulose, yomwe ndi polymer yachilengedwe yomwe ili m'makoma a cell a mbewu. HPMC imapangidwa kudzera mu njira yosinthira mankhwala yomwe imaphatikizapo kuchiritsa cellulose ndi ma propyl oxide ndi methyl chloride.
HPMC ndi ufa woyera, wopanda fungo womwe umasungunuka m'madzi ndikupanga gel gel gel utasungunuka. Ili ndi ntchito zingapo pamakampani osiyanasiyana chifukwa cha zovuta zake.
Nawa mawonekedwe ofunikira a HPMC:
Mchitumiki wa Kukula:HPMC ndi yogwira mtima kwambiri komanso ma vinyadi osintha. Imatha kuwonjezera mamasukidwe amamwa, kupangitsa kuti ikhale yothandiza pazinthu zosiyanasiyana zomwe zimafuna kusasinthika kapena kusinthika.
Katundu wopanga makanema:HPMC imatha kupanga filimu yochepetsetsa, yosinthika ikagwiritsidwa ntchito pamwamba. Katunduyu nthawi zambiri amagwiritsidwa ntchito mu zokutira, utoto, ndi mapulogalamu ena omwe amafuna chitetezo kapena chotchinga.
Kusunga kwamadzi:HPMC ili ndi madzi abwino osunga madzi, kulola kuti isunge chinyontho mu mapangidwe. Izi zimapangitsa kuti zizithandiza pantchito monga zinthu za simenti, komwe zimathandizira kutha komanso kuchepetsa shrinkage.
Emulsion Statefar:HPMC imatha kukhazikika m'mawu, kupewa kuyeretsa mafuta ndi madzi. Nthawi zambiri amagwiritsidwa ntchito popanga zodzola komanso zinthu zosamalira payekha kuti zizikhazikika komanso kusasinthika kwa mafuta, mafuta odzola, ndi emulsions ina.
Olamulidwa ndi katundu:HPMC imatha kuwongolera kutulutsidwa kwa zosakaniza zogwira, makamaka m'makampani opanga mankhwala. Itha kupanga gel onrix yomwe imachepetsa kumasulidwa kwa mankhwalawa, kumapangitsa kuti atulutsidwe nthawi yayitali.
Osakhala ochezeka komanso ochezeka:HPMC imawonedwa kuti igwiritsidwe ntchito pamapulogalamu osiyanasiyana. Sikuti siabwaloti, biodeggradglen, ndipo samakhala pachiwopsezo cha thanzi la anthu kapena chilengedwe.
Ponseponse, HPMC imasinthasintha ndipo imagwiritsidwa ntchito mosiyanasiyana m'mafakitale monga mankhwala opangira mafakitale, zomanga, chakudya, kusamalira payekha, zopereka, ndi ulimi. Kutha kwake kusintha ma Isccect, kusunga chinyontho, kukhazikika kwa mapangidwe, kusuta kwa ulamuliro kumapangitsa kuti ikhale yowonjezera mtengo.
Karata yanchito
Hydroxypropyl me cellose (hpmc) ndi hydrocoolloolloid omwe achokera ku cellulose yochokera ku cellulose, polymer achilengedwe omwe amapezeka m'makoma a cell a mbewu. HPMC imagwiritsidwa ntchito poyerekeza ndi mafakitale osiyanasiyana chifukwa cha zovuta zake.
Nazi ntchito zodziwika bwino za HPMC:
Makampani opanga mankhwala: HPMC imagwiritsidwa ntchito kwambiri makampani opanga mankhwala ngati mankhwala ophatikizira. Amagwiritsidwa ntchito pa piritsi ngati chofunda, filler, ndi kuwonongeka. HPMC imatha kusintha kusungunuka ndi bioavailability kwa mankhwalawa popereka katundu woponderezedwa.
Makampani omanga: HPMC imagwiritsidwa ntchito pomanga mafakitale omanga ngati thiccener, wosunga madzi, ndi binder. Zimawonjezeredwa ndi zinthu zophatikizira za sile monga mataunje, groutso, pulasitala, ndi matope kuti athetse kuvuta, kusungidwa kwamadzi, komanso kutsatira.
Makampani Ogulitsa Chakudya:HPMC imagwiritsidwa ntchito ngati chowonjezera mu malonda azakudya pomwe zimagwira ngati chitsime, kukhazikika, ndi emulsifier. Imagwiritsidwa ntchito muzopanga monga mavalidwe saladi, ndowe, kudzazidwa, ndi ayisikilimu kuti musinthe mawonekedwe, mafakisoni, komanso kukhazikika.
Zogulitsa Zaumwini:HPMC imagwiritsidwa ntchito pazinthu zaumwini monga zonona, zotupa, ndi shampoos ngati thiccener komanso kusinthika kosatha. Imapereka kusasinthika kosalala ndi kolona yofananira ku zinthu izi ndikuwonjezera kukhazikika kwawo.
Utoto ndi zokutira:HPMC imawonjezeredwa ndi zokutira zochokera m'madzi ndikukutira kuti azitha kukulitsa makulidwe awo, pewani kusamba, komanso kupititsa patsogolo. Imagwiranso ntchito ngati chokhazikika komanso chowongolera choyenda ndi chowongolera utoto.
Makampani opanga zaulimi:HPMC imagwiritsidwa ntchito pakugwirira ntchito zaulimi ndi wothandizira makanema mu sprays ndi zokutira. Zimakhala bwino pakutsatira mankhwala ophera tizilombo ndi feteleza kuti azikhala pamalo ophuka, akulimbika mphamvu yawo.
Makampani opanga malemba:HPMC imagwiritsidwa ntchito posindikiza mawonekedwe ndi kukonza njira ngati thicker yosindikiza pastes. Zimathandizira kuwongolera mapangidwe a phazi losindikiza ndikusintha mawonekedwe ndi kukomoka zipatso.
Awa ndi zitsanzo zochepa chabe za ntchito zambiri za hydroxypropyl methy celluse. Kusintha kwake, kukhazikika, komanso kusakhalana kwa poizoni kumapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
