Kusanthula mozama kachitidwe kakusunga madzi ka hydroxypropyl methylcellulose (HPMC)

dziwitsani:

Hydroxypropylmethylcellulose (HPMC) ndi mankhwala ambiri omwe amagwiritsidwa ntchito kwambiri m'mafakitale angapo chifukwa cha zopindulitsa zake zosiyanasiyana. Ndiwochokera ku cellulose, yomwe imapezeka posintha ma cellulose ndi propylene oxide ndi methyl chloride. HPMC imagwiritsidwa ntchito kwambiri m'mafakitale opanga mankhwala, chakudya, zomangamanga ndi zodzikongoletsera chifukwa cha malo ake abwino osungira madzi. Pepalali likupereka kuwunika mozama momwe HPMC imasungira madzi.

Kusunga madzi kwa HPMC:

The madzi posungira katundu HPMC ndi chimodzi mwa zifukwa zofunika kwambiri ntchito yake ponseponse m'mafakitale angapo. HPMC ali mkulu mphamvu posungira madzi chifukwa hydrophilic chikhalidwe. Imayamwa madzi ndikutupa kuwirikiza kangapo kukula kwake koyambirira, ndikupangitsa kukhala chosungira bwino kwambiri chamadzi. The madzi posungira katundu HPMC zimadalira zinthu zingapo monga mlingo wa m'malo, mamasukidwe akayendedwe a HPMC yankho, ndi mtundu wa zosungunulira ntchito.

Digiri ya m'malo:

Digiri ya m'malo (DS) ya HPMC ndi chinthu chofunikira chomwe chimakhudza kasungidwe ka madzi. DS ya HPMC imatanthawuza kuchuluka kwa magulu a hydroxyl osinthidwa ndi magulu a hydroxypropyl ndi methyl mu molekyulu ya cellulose. HPMC yokhala ndi digiri yapamwamba yolowa m'malo imakhala ndi mphamvu yosungira madzi kuposa HPMC yokhala ndi m'malo ochepa. Ma DS apamwamba a HPMC amawonjezera hydrophilicity ya molekyulu, zomwe zimapangitsa kuti madzi azikhala bwino.

Viscosity ya HPMC solution:

Kukhuthala kwa njira ya HPMC ndi chinthu china chomwe chimakhudza kasungidwe ka madzi ka HPMC. Kukhuthala kwa njira ya HPMC kumawonjezeka ndi kuchuluka kwa ndende ya HPMC mu zosungunulira. Chifukwa cha kukhalapo kwa mamolekyu ambiri a HPMC mu zosungunulira, kukwezera kukhuthala kwa njira ya HPMC kumapangitsa kuti madzi asungidwe bwino. High viscosity HPMC mayankho amapanga mawonekedwe ngati gel osakaniza kuti amakola mamolekyu amadzi ndikuwaletsa kuti asatuluke.

Mtundu wosungunulira wogwiritsidwa ntchito:

Mtundu wa zosungunulira zomwe zimagwiritsidwa ntchito pokonzekera yankho la HPMC zingakhudzenso zomwe zimasunga madzi. HPMC ndi sungunuka m'madzi ndi zosungunulira zosiyanasiyana organic, monga alcohols, esters, ndi ketoni. Zosungunulira zomwe zimagwiritsidwa ntchito pokonzekera yankho la HPMC zimatha kukhudza kutupa kwa molekyulu. HPMC imatupa kwambiri m'madzi ndipo imamwa madzi ambiri kuposa HPMC mu zosungunulira za organic. Poyerekeza ndi organic zosungunulira njira, HPMC ali bwino madzi posungira katundu mu amadzimadzi mayankho.

Kugwiritsa ntchito HPMC m'mafakitale osiyanasiyana:

Chifukwa cha malo ake abwino osungira madzi, HPMC imagwiritsidwa ntchito kwambiri m'mafakitale angapo monga mankhwala, chakudya, zomangamanga ndi zodzoladzola.

Makampani opanga mankhwala:

M'makampani opanga mankhwala, HPMC imagwiritsidwa ntchito ngati binder, disintegrant and coating agent. Amagwiritsidwa ntchito ngati chomangira pokonzekera mapiritsi kuti agwirizanitse zosakaniza pamodzi. Monga disintegrant, HPMC imathandiza kuthyola piritsilo kukhala tinthu ting'onoting'ono m'mimba, zomwe zimathandizira kuyamwa kwa mankhwala. HPMC imagwiritsidwa ntchito ngati zokutira kuteteza mankhwalawa ku chinyezi komanso kuwongolera kutulutsidwa kwa mankhwala.

makampani azakudya:

M'makampani azakudya, HPMC imagwiritsidwa ntchito ngati emulsifier, stabilizer ndi thickener. Amagwiritsidwa ntchito popangira mafuta ndi zakumwa zamadzimadzi, kukhazikika kwa zakudya, ndikulimbitsa ma sauces ndi gravies. HPMC imagwiritsidwanso ntchito ngati chodzaza kuwonjezera zakudya zambiri.

Makampani omanga:

M'makampani omanga, HPMC imagwiritsidwa ntchito kwambiri pazinthu zopangira simenti monga matope ndi konkriti. Amagwiritsidwa ntchito ngati chosungira madzi kuti asatuluke m'madzi osakaniza a simenti. HPMC imathanso kupititsa patsogolo kusakanikirana kwa simenti ndikuchepetsa kuwonongeka kwa zinthuzo.

Makampani opanga zodzoladzola:

M'makampani opanga zodzikongoletsera, HPMC imagwiritsidwa ntchito ngati thickener, emulsifier and conditioning agent. Amagwiritsidwa ntchito kulimbitsa mafuta odzola ndi zonona, emulsify mafuta ndi zopangira madzi, komanso tsitsi.

Pomaliza:

Pomaliza, katundu wosungira madzi wa HPMC ndi imodzi mwazinthu zofunika kwambiri komanso zopindulitsa. HPMC ili ndi mphamvu yosungira madzi chifukwa cha chikhalidwe chake cha hydrophilic, chomwe chimawathandiza kuti azitha kuyamwa ndi kusunga madzi ndikuletsa kuti asatuluke. Mlingo wolowa m'malo, kukhuthala kwa yankho ndi mtundu wa zosungunulira zomwe zimagwiritsidwa ntchito ndizofunikira zomwe zimakhudza magwiridwe antchito a HPMC posungira madzi. HPMC chimagwiritsidwa ntchito m'mafakitale osiyanasiyana monga mankhwala, chakudya, zomangamanga ndi zodzoladzola chifukwa katundu wake kwambiri madzi posungira.
