MukasankhaHydroxypropyl Methylcellulose (HPMC)Kuwunika momwe madzi amasungidwira ndi chizindikiro chofunikira kwambiri, makamaka pakugwiritsa ntchito m'magawo omanga, mankhwala, zodzoladzola, ndi zina zotero. Kusunga madzi kumakhudza mwachindunji magwiridwe antchito ake mu kapangidwe kake, monga kumatira, kusinthasintha komanso kukhazikika.
1. Kapangidwe ka mamolekyulu ndi kulemera kwa mamolekyulu
Kulemera kwa mamolekyulu a AnxinCel®HPMC ndi kapangidwe kake ka mamolekyulu zimakhudza mwachindunji momwe amasungira madzi. Kawirikawiri, kulemera kwa mamolekyulu a HPMC kukakhala kwakukulu, kumasunga madzi bwino. HPMC yokhala ndi kulemera kwakukulu kwa mamolekyulu imakhala ndi kapangidwe kautali ka unyolo, komwe kamatha kuyamwa madzi ambiri ndikupanga kapangidwe kokhazikika ka gel.
HPMC yolemera kwambiri: Ili ndi kusungunuka kochepa m'madzi, koma imatha kusunga madzi bwino, ndipo ndi yoyenera kugwiritsidwa ntchito ndi zinthu zomwe zimafunika kusunga madzi ambiri, monga matope omangira, zokutira, ndi zina zotero.
Kulemera kochepa kwa mamolekyulu HPMC: Kusunga madzi molakwika, koma kusayenda bwino kwa madzi, koyenera kupanga zinthu zomwe zimafuna kuuma mwachangu kapena kuumitsa mwachangu.
2. Kuchuluka kwa hydroxypropyl
Kuchuluka kwa hydroxypropyl kumatanthauza kuchuluka kwa magulu a hydroxypropyl m'mamolekyu a HPMC, omwe nthawi zambiri amafotokozedwa ngati kuchuluka kwa mass percentage. Kuchuluka kwa hydroxypropyl kumakhudza kusungunuka, kukhuthala ndi kusunga madzi kwa HPMC.
HPMC yokhala ndi hydroxypropyl yambiri: imatha kusungunuka bwino m'madzi ndikuwonjezera madzi, kotero imakhala ndi madzi okwanira ndipo ndi yoyenera kugwiritsidwa ntchito m'malo okhala ndi chinyezi chambiri.
HPMC ili ndi hydroxypropyl yochepa: kusungunuka kochepa, koma ikhoza kukhala ndi kukhuthala kwakukulu, komwe kuli koyenera kwambiri pazinthu zina monga zokutira zokhuthala.
3. Kusungunuka
Kusungunuka kwa HPMC ndi chimodzi mwazinthu zofunika kwambiri poyesa kusunga madzi ake. Kusungunuka bwino kumathandiza kuti imwazike mofanana m'madzi, motero imakhala ndi mphamvu yabwino yosunga madzi.
Kusungunuka kwa madzi ofunda: Ma HPMC ambiri amasungunuka mosavuta m'madzi ofunda. HPMC yosungunuka imatha kupanga yankho la colloidal, lomwe limathandiza kuti likhale lonyowa mu simenti ndipo limaletsa madziwo kuti asatuluke msanga.
Kusungunuka kwa madzi ozizira: Pazinthu zomwe ziyenera kugwiritsidwa ntchito m'malo otentha pang'ono, HPMC yokhala ndi kusungunuka kwa madzi ozizira bwino ndiyo yoyenera. Mtundu uwu wa HPMC ukhoza kusungunuka mwachangu kutentha kwa chipinda kapena kutentha kochepa kuti zitsimikizire kuti madzi amasungidwa panthawi yomanga.
4. Kugawa kukula kwa tinthu
Kukula kwa tinthu ta HPMC kumakhudza mwachindunji kuchuluka kwa kusungunuka kwake ndi momwe madzi amagwirira ntchito. HPMC yokhala ndi tinthu tating'onoting'ono imasungunuka mwachangu ndipo imatha kutulutsa madzi mwachangu mu dongosolo, zomwe zimapangitsa kuti madzi ake asungidwe bwino. Ngakhale kuti HPMC yokhala ndi tinthu tating'onoting'ono timasungunuka pang'onopang'ono, imatha kupanga madzi okhazikika mu dongosolo, kotero kuti kusunga madzi kumakhala kolimba.
Tinthu tating'onoting'ono ta HPMC: Ndi yoyenera kugwiritsidwa ntchito zomwe zimafuna kusungunuka mwachangu, zimatha kutulutsa madzi mwachangu, ndipo ndi yoyenera zinthu monga matope osakanikirana ndi zomatira zomwe zimafuna madzi ambiri oyamba.
Tinthu tating'onoting'ono ta HPMC: Ndi toyenera kwambiri pazochitika zomwe zimafuna kuti madzi asungidwe kwa nthawi yayitali, monga matope a simenti omwe amakhala nthawi yayitali, zomangira mu zipangizo zomangira, ndi zina zotero.
5. Kuchuluka kwa chinyezi
Kuchuluka kwa chinyezi mu HPMC kudzakhudzanso momwe imasungira madzi. Kuchuluka kwa chinyezi kungapangitse HPMC kusintha magwiridwe ake panthawi yosungira ndi kugwiritsa ntchito. Chifukwa chake, HPMC youma nthawi zambiri imakhala ndi nthawi yayitali yosungira komanso magwiridwe antchito okhazikika. Mukasankha, samalani ndi kuchuluka kwa chinyezi chake kuti mupewe kuchuluka kwa chinyezi komwe kungakhudze momwe imagwiritsidwira ntchito.
6. Kukana kutentha
Kusunga madzi kwa HPMC kumagwirizananso kwambiri ndi kukana kutentha kwake. Ntchito zina zingafunike kuti HPMC ikhale ndi madzi okwanira kutentha kwambiri. Mwachitsanzo, zokutira zomangamanga zingafunike kugwiritsidwa ntchito kutentha kwambiri panthawi yomanga. Kusankha HPMC yokhala ndi kukana kutentha kwambiri kungatsimikizire kuti madzi amasungidwa bwino panthawi yomanga ndikuletsa kuti zinthuzo ziume mofulumira kwambiri.
7. Kukhazikika
Kukhazikika kwa HPMC kudzakhudzanso kusunga madzi ake pansi pa pH ndi kutentha kosiyanasiyana. HPMC yokhazikika imatha kusunga madzi kwa nthawi yayitali m'malo osiyanasiyana, makamaka m'malo amphamvu a alkaline kapena acidic monga simenti kapena gypsum. Ndikofunikira kusankha HPMC yokhala ndi kukhazikika kwamphamvu. Ngati kukhazikika kwa mankhwala a HPMC kuli koipa, kusunga madzi kwake kungachepe pakapita nthawi, zomwe zingakhudze magwiridwe antchito omaliza.
8. Zowonjezera ndi mankhwala pamwamba
Zinthu zina za HPMC zimawonjezera zinthu zina zapadera kapena zowonjezera pakupanga kuti ziwongolere kusunga madzi. Mwachitsanzo, powonjezera ma polima ena kapena ma colloid, mphamvu yosungira madzi ya HPMC ikhoza kuwonjezeredwa. Kuphatikiza apo, zinthu zina zimawonjezera kusinthasintha kwawo powonjezera zinthu zoletsa kuyika, zomwe zimapangitsa HPMC kukhala yosavuta kugwiritsa ntchito.
9. Njira zoyesera
Posankha HPMC, njira zina zoyesera zingagwiritsidwe ntchito poyesa kusunga madzi m'thupi. Mwachitsanzo:
Kuyesa kuyamwa madzi: Dziwani kuchuluka kwa madzi omwe HPMC ingathe kuyamwa pakapita nthawi inayake.
Kuyesa mphamvu yosungira madzi: Yesani mphamvu ya AnxinCel®HPMC yosungira madzi posakaniza pogwiritsa ntchito njira yopangira zinthu.
Kuzindikira kukhuthala: Kukhuthala kumakhudza mwachindunji madzi ake. Kusunga madzi kwake kumayesedwa ndi kukhuthala. HPMC yokhala ndi kukhuthala kwakukulu nthawi zambiri imakhala ndi kusungira madzi bwino.
Mukasankha choyeneraHPMC, ndikofunikira kuganizira zinthu zingapo mozama monga kulemera kwa mamolekyulu, digiri ya hydroxypropyl, kusungunuka, kugawa kwa tinthu tating'onoting'ono, kukana kutentha, kukhazikika, ndi zina zotero. Malinga ndi zosowa zosiyanasiyana za ntchito zenizeni, sankhani mtundu woyenera wa chinthu cha HPMC kuti muwonetsetse kuti magwiridwe ake pakusunga madzi akukwaniritsa zofunikira. Makamaka m'mafakitale omanga ndi opanga mankhwala, kusunga madzi kwa HPMC sikungokhudza momwe chimangidwira, komanso kungakhudze mtundu womaliza wa chinthucho, kotero chiyenera kusankhidwa mosamala kwambiri.
