Kodi hpmc yoyatsira moto?

Hydroxypropyl methylcellulose (hpmc) ndi polymer polymer omwe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana kuphatikiza mankhwala opangidwa, chakudya, zomangamanga. Gawo lofunikira pazinthu zilizonse, makamaka lomwe limagwiritsidwa ntchito mu magwiridwe angapo, ndi kusokonekera kwake. Kuchita zinthu kumatanthauza kuthekera kwa chinthu kuti muchotse ndikuzisunga kuti ziwotchedwa pansi pa zinthu zina. Pankhani ya HPMC, nthawi zambiri imaganiziridwa kuti sizachikhalidwe kapena zimakhala ndi zowoneka bwino kwambiri. Komabe, ndikofunikira kudziwa zambiri izi mwatsatanetsatane kuti mumvetsetse zinthu zomwe zimapangitsa kuti ndikhale yopanda tanthauzo, machitidwe ake mosiyanasiyana komanso malingaliro aliwonse okhudzana ndi kugwiritsa ntchito kwake.

Kapangidwe ka 1.Chemical:
HPMC ndi polder postmer yopangidwa ndi celluluse, polymer yachilengedwe imapezeka mu makhola a cell. Hydroxypyl ndi methyl amayambitsidwa kudzera pakusintha kwamankhwala kuti muwonjezere madzi osungunuka ndi zinthu zina za cellulose. Maseloni pawokha siyakayaka kwambiri, ndipo sizikudziwika kuti ngati mabungwe a mankhwala awa amawonjezera zinthu zowoneka bwino. Kapangidwe ka mankhwala kwa HPMC kumawonetsa kuti kumakhala koyipa kwambiri komwe kumalumikizidwa ndi mankhwala opangira nyama.

2.
TGA ndi njira yomwe imagwiritsidwa ntchito pophunzira kukhazikika kwa matenthedwe ndi kuwonongeka kwa zida. Kafukufuku wa HPMC pogwiritsa ntchito TGA awonetsa kuti nthawi zambiri imadumphadumpha musanafike pamalopo osawoneka bwino. Zochita zowonongeka nthawi zambiri zimakhala zamadzi, mpweya woipa, ndi zina zosasinthika.

3.. Kutentha kutentha:
Kutentha kowonongeka ndi kutentha kochepa kwambiri komwe chinthu kumatha kuyatsa ndikuchirikiza kuyamwa. HPMC ili ndi kutentha kwambiri ndipo sikungatheke. Kutentha kwenikweni kumatha kusiyanasiyana kutengera kalasi yakeyo ndi kapangidwe ka HPMC.

4. Kuchepetsa Index (Loi):
Loi ndi muyeso wa zinthu zakuthupi, zomwe zimayesedwa ngati mpweya wocheperako wofunikira kuti athandizire kuyaka. Zikhulupiriro zapamwamba za Loi zimawonetsa kuchepa kwamphamvu. HPMC nthawi zambiri imakhala ndi loi wapamwamba, kuwonetsa kuti kuyaka kwake kumafuna mpweya wambiri.

5. Ntchito zofunikira:
HPMC imagwiritsidwa ntchito m'makampani opanga mankhwala, komwe miyezo yokhazikika ndiyovuta. Kuwonongeka kwake kochepa kumapangitsa kuti ikhale chisankho choyamba pazinthu zomwe chitetezo chamoto chimadera nkhawa. Kuphatikiza apo, HPMC imagwiritsidwa ntchito pomanga monga matope a simenti, pomwe zomwe sizimayamwa ndi mwayi.

6. Kusamala:
Pomwe hpmc payokha sizayaka kwambiri, mawonekedwe athunthu ndipo zowonjezera zilizonse ziyenera kuganiziridwa. Zowonjezera zina zimatha kukhala ndi mawonekedwe osiyanasiyana odzikongoletsa. Zochita zoyenera komanso zosungira ziyenera kutsatiridwa kuti zitsimikizidwe kuti ndi chitetezo chantchito komanso kupewa ngozi mwangozi.

7. Malangizo ndi miyezo:
Mabungwe osiyanasiyana oyang'anira, monga FDA (Chakudya ndi mankhwala osokoneza bongo) ndi mabungwe ena amtundu wa mayiko, ali ndi malangizo okhudzana ndi zinthu zomwe zimagwiritsidwa ntchito mu mapulogalamu osiyanasiyana. Malamulowa nthawi zambiri amaphatikizapo malingaliro achitetezo a moto. Kutsatira malamulowa kumatsimikizira kuti zinthu zomwe zili ndi HPMC zimakwaniritsa miyezo yapadera.

Hpmc nthawi zambiri zimaganiziridwa kuti sizabwino kapena zimakhala ndi zowoneka bwino kwambiri. Kapangidwe kake, kutentha kwakukulu ndi zinthu zina zamafuta zimathandizira kuti aziteteza m'njira zosiyanasiyana. Komabe, mawonekedwe athunthu ndipo zowonjezera zilizonse zomwe zilipo ziyenera kuonedwa ngati malangizo ndi malamulo otetezeka nthawi zonse kuti mutsimikizire kugwiritsa ntchito bwino komanso kugwiritsa ntchito bwino mafakitale osiyanasiyana.
