Kodi mamasukidwe a hydroxypypyll methylcelulose?

Hydroxypypyl nothycellulose (hpmc) ndi yofinya, nthumwi ndi kanema wakale zakale zomwe zimagwiritsidwa ntchito mu mankhwala, chakudya, zodzikongoletsera komanso zopangira mafakitale. Chidwi chake ndi chimodzi mwazinthu zofunika zomwe zimakhudza momwe amagwirira ntchito, zomwe nthawi zambiri zimasiyana malinga ndi zinthu monga njira yothetsera mavuto, kutentha komanso kutentha kwa HPMC.

Mtengo wa Viscc wa HPMC amatanthauza madzi osintha m'njira zina m'mikhalidwe ina, yomwe nthawi zambiri imafotokozedwa mu MPPI (Masekondi a Millipascal). Pakusintha mu HPMC, ndende yodziwika ndi 2% kapena 4% yankho, ndipo kutentha kwa muyeso nthawi zambiri ndi 20 ° C kapena 25 ° C kapena 25 ° C. Kutengera mtundu ndi chinthu, mamasuwa a HPMC amatha kukhala ndi makhadi okwana mazana angapo ku Rop ku Mafumu ocheperako.

Zotsatirazi ndi zinthu zazikulu zomwe zimakhudza mafayilo a HPMC:

Kulemera kwa maselo: Kukulira kwakukulu kwa HPMC, kukweza ma viscy. HPMC yokhala ndi kulemera kwambiri kumatha kupanga kuyanjana kwambiri pa yankho, motero kumawonetsa kukweza kwambiri.

Hydroxypyl ndi methyl polowerera: Kukwera kwambiri kwa hydroxypropyl (-oh) ndi methyl (-ch₃) Kuchuluka kwa hydroxypropyll kumatha kusintha solubility ya HPMC, pomwe methylation imathandizira ma visni.

Njira Yothetsera: Kutenga kwa HPMC yankho mwachindunji kumakhudzanso mamasuki. Kukula kwakukulu, mafayilo akulu. Nthawi zambiri, zothetsera mavuto pakati pa 2% ndi 5% ndizofala kwambiri, ndipo mafayilo othetsera mavuto ambiri azikhala apamwamba.

Zosungunulira: HPMC imasungunuka bwino m'madzi, kotero ma viscCy imangoyesedwa chifukwa cha mayankho am'madzi. Komabe, mitundu yosiyanasiyana ya ma sol sol imathanso imakhudzanso kususuka komanso mafayilo.

Kutentha: Kutentha kumakhala ndi mphamvu kwambiri pakukweza kwa HPMC. Nthawi zambiri, kuchuluka kwa kutentha kumabweretsa kuchepa kwa kusintha kwa ma visct chifukwa kutentha kwambiri kumathandizira kuyenda kwa moleccular ndikuwonjezera madzi othetsera vutoli.

Maviyo a HPMC nthawi zambiri amagwiritsidwa ntchito m'minda yotsatirayi:

Gawo la mankhwala: Imagwiritsidwa ntchito ngati mankhwala omasulidwa ndi mankhwala osokoneza bongo, piritsi la tebulo, ndi gawo la zipolopolo. Itha kuonetsetsa kumasulidwa kwa mankhwalawa mwa kuwongolera mafayilo.

Makampani ogulitsa zakudya: ogwiritsidwa ntchito ngati chulukidwe, imatha kukonza bwino kukoma ndi mawonekedwe a ayisikilimu, odzola, maswiti, ndi zina.

Makampani omanga: Kugwiritsa ntchito ngati thickiner ndi wogulitsa madzi pakupanga zinthu zomanga monga simenti ndikuwongolera kusintha madzi ndi magwiridwe antchito.

Makampani opanga zodzikongoletsera: ogwiritsidwa ntchito muzogulitsa monga zonona, zoyeretsa za nkhope, mithunzi yamaso, etc. Kupereka mamasukidwe abwino komanso kukhazikika.

Mukamasankha zopangidwa zabwino za HPMC, ndikofunikira kuti timvetsetse mawonekedwe ake, makamaka zofuna zamadzi ndi kukhazikika pamapulogalamu osiyanasiyana. Ngati pali chofunikira kwambiri kuti muwone phindu lina la HPMC inayake, mutha kutanthauza zofunikira pazomwe zimapanga kapena kuziyesa ndi chida choyezera.
