Low-replacement Hydroxypropyl Methylcellulose (HPMC) ndi mtundu wa cellulose yochokera ku cellulose yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza mankhwala, zomangamanga, chakudya, ndi zodzola.Amachokera ku cellulose, yomwe ndi polima yachilengedwe yomwe imapezeka muzomera.HPMC imasinthidwa kudzera muzochita zamakina kuti ipititse patsogolo mawonekedwe ake pazinthu zina.HPMC yolowa m'malo yochepa nthawi zambiri imakhala ndi DS yotsika poyerekeza ndi HPMC wamba, zomwe zimapangitsa kuti pakhale mawonekedwe osiyanasiyana komanso magwiridwe antchito osiyanasiyana.
Mawonekedwe a Low-Replacement HPMC:
Chilengedwe cha Hydrophilic: Monga zotengera zina za cellulose, HPMC yotsika m'malo mwake ndi hydrophilic, kutanthauza kuti ili ndi mgwirizano wamadzi.Katunduyu amapangitsa kuti ikhale yoyenera kugwiritsa ntchito komwe kusungirako chinyezi, kukhuthala, kapena kupanga mafilimu kumafunikira.
Kukhazikika kwa Matenthedwe: HPMC imawonetsa kukhazikika kwamafuta, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'mapangidwe omwe amakonzedwa kapena kukhudzidwa ndi kutentha kokwera.
Kutha Kupanga Mafilimu: HPMC yotsika pang'ono imatha kupanga mafilimu owonekera komanso osinthika akauma, zomwe zimapangitsa kuti zikhale zothandiza m'mafakitale osiyanasiyana, kuphatikizapo mankhwala ndi zakudya, zopangira mapiritsi kapena zopangira zopangira.
Kukula ndi Kusintha kwa Rheology: HPMC ndi njira yolimbikitsira ndipo imatha kusintha machitidwe amadzimadzi.Mu mawonekedwe otsika-m'malo, amapereka zolimbitsa mamasukidwe kuwongola, kulola kulamulira yeniyeni pa otaya katundu wa formulations.
Kugwirizana kwa Chemical: Zimagwirizana ndi zina zambiri zomwe zimagwiritsidwa ntchito popanga, kuphatikizapo mchere, shuga, surfactants, ndi organic solvents.Kusinthasintha kumeneku kumathandizira kuti igwiritsidwe ntchito kwambiri m'mafakitale osiyanasiyana.
Nature Non-Ionic: Low-placement HPMC si-ionic, kutanthauza kuti ilibe mphamvu yamagetsi yothetsera.Katunduyu amalola kuti azigwirizana ndi mitundu yambiri yamankhwala ena ndipo amachepetsa chiwopsezo cha kuyanjana komwe kungakhudze kukhazikika kapena magwiridwe antchito a mapangidwe.
Biodegradability: Popeza imachokera ku cellulose, HPMC imatha kuwonongeka pansi pamikhalidwe yoyenera, yomwe ndi yofunika kwambiri pakugwiritsa ntchito zinthu zachilengedwe.
Mapulogalamu a Low-Replacement HPMC:
Zamankhwala:
Kupaka Mapiritsi: HPMC yotsika m'malo mwake ingagwiritsidwe ntchito kupanga zokutira yunifolomu ndi zoteteza pamapiritsi, kupereka kumasulidwa kolamulidwa kapena kubisala kukoma.
Mapangidwe Otulutsidwa Oyendetsedwa: Amagwiritsidwa ntchito m'makina a matrix kuti atulutse mosalekeza kapena mosasunthika kwa zinthu zomwe zimagwira ntchito pamankhwala.
Ophthalmic Solutions: HPMC imagwiritsidwa ntchito m'madontho a m'maso ndi mafuta odzola chifukwa cha zomatira zake komanso kugwirizana ndi minyewa yamaso.
Zomangamanga:
Zomatira za matailosi: HPMC imagwira ntchito ngati chowonjezera komanso chosungira madzi muzomatira zamatayilo, kuwongolera magwiridwe antchito ndi zomatira.
Mitondo Yopangidwa ndi Simenti: Imakulitsa kugwirira ntchito, kusunga madzi, ndi kumamatira mumatope opangidwa ndi simenti, monga ma renders, pulasitala, ndi ma grouts.
Zipangizo za Gypsum: HPMC yolowa m'malo yochepa imapangitsa kuti zinthu zopangidwa ndi gypsum zikhale zolimba komanso zogwira ntchito ngati zophatikizika ndi pulasitala pakhoma.
Chakudya ndi Zakumwa:
Emulsions ndi Kuyimitsidwa: HPMC imakhazikika emulsions ndi kuyimitsidwa, kuteteza kupatukana kwa gawo ndikuwongolera kapangidwe kake ndi pakamwa pazakudya.
Zophika Zophika: Zimawonjezera kukhuthala kwa mtanda, mawonekedwe ake, komanso moyo wa alumali muzophika monga buledi, makeke, ndi makeke.
Zamkaka: HPMC itha kugwiritsidwa ntchito pazakudya zamkaka monga yoghurt ndi ayisikilimu kuti mukhale okhazikika komanso mawonekedwe.
Zodzisamalira Pawekha ndi Zodzoladzola:
Zinthu Zosamalira Khungu: HPMC imagwiritsidwa ntchito muzopaka, mafuta odzola, ndi ma gels monga thickener ndi stabilizer, kupereka zofunika maonekedwe ndi rheology.
Zopangira Tsitsi: Zimathandizira kukhuthala komanso kuyimitsa mawonekedwe a shampoos, zowongolera, ndi masitayelo.
Mapangidwe apamutu: HPMC imaphatikizidwa m'mapangidwe apamutu monga mafuta odzola ndi ma gelisi pakupanga mafilimu ndi kunyowetsa.
Paints ndi Zopaka:
Latex Paints: HPMC imagwira ntchito ngati thickener ndi stabilizer mu madzi opangidwa ndi latex utoto, kukonza brushability, spatter resistance, ndi kukhulupirika filimu.
Zovala Zapadera: Zimagwiritsidwa ntchito muzovala zapadera monga zophimba zotsutsana ndi graffiti ndi zokutira zosagwira moto chifukwa cha kupanga mafilimu ndi chitetezo.
Mapulogalamu Ena:
Zomatira: HPMC yosinthira pang'ono imathandizira kukhuthala, kugwirira ntchito, ndi kumamatira kwa zomatira, kuphatikiza phala lapamwamba, zomatira zamatabwa, ndi zosindikizira.
Kusindikiza Zovala: Zimagwiritsidwa ntchito posindikiza nsalu kuti ziwongolere kukhuthala ndikuwongolera matanthauzidwe osindikiza ndi zokolola zamitundu.
Pomaliza:
Low-replacement Hydroxypropyl Methylcellulose (HPMC) ndi chochokera ku cellulose yosunthika yomwe imagwiritsidwa ntchito mosiyanasiyana pamankhwala, zomangamanga, chakudya, zodzoladzola, ndi mafakitale ena.Makhalidwe ake apadera, kuphatikizapo hydrophilicity, luso lopanga mafilimu, ndi chikhalidwe chosakhala cha ionic, zimapangitsa kuti zikhale zofunikira kwambiri pakupanga zosiyanasiyana.Kaya monga chotchingira piritsi, chokhuthala muzakudya, kapena rheology modifier muzomangamanga, HPMC yotsika pang'ono imathandizira kuti pakhale magwiridwe antchito, kukhazikika, ndi magwiridwe antchito amitundu yambiri.Kuphatikiza apo, kuwonongeka kwake kwachilengedwe kumawonjezera chidwi chake pantchito zosamala zachilengedwe.
