HPMC (hydroxypropopalsel mathylcellse) he wai wai wai-wai nui i hoʻohana nuiʻia ma ka lāʻau lapaʻau, meaʻai,ʻai, nā hana, nā mea'ē aʻe a me nāʻoihana'ē aʻe. Ua loaʻaʻo HPMC kahi DEMU-synthetic cedit i loaʻaʻia e ka hoʻololiʻana o ka chemikina o ka cellulose maoli, a hoʻohana pinepineʻia e like me ka skickener, scabiliier
Nā mea pilikino o HPMC
ʻOi aku ka paʻakikī o ka HPMC o ka HPMC no ka meaʻaʻole eʻikeʻia kona wahi e like me ka mea e like me nā mea maʻamau crystalline maʻamau. Ua hoʻopilikiaʻia kona wahi mening me Molecular, Molecular a me ke kiʻekiʻe o ka hoʻololiʻana i nā hui hydrocypopyl a me nā hui uila e like me ka huahana hpmc. ʻO ka maʻamau,ʻo ia kahi polymer wai,ʻaʻole i loaʻa ka HPMC a me nā mea e hoʻomaʻemaʻeʻia a me nā mea hoʻonaninani i loko o kekahi mau mahana.
Malting point
ʻO keʻano o ka hanaʻana o ka hopohopo o ka hopohopo Mai ka palapala kākau, hiki keʻikeʻia e like me ka laulā o ka hpmc ma waena o 200°C a me 300°C, akāʻaʻole e hōʻikeʻia kēiaʻano i keʻano o ka Mengling Living i nā huahana HPMC āpau. ʻO nāʻano likeʻole o nā huahana HPMC e loaʻa paha i nā wahi'ē aʻe e like me nā mea e like me nā mea e like me keʻano o ka moddroxlation).
ʻO ka molena molela haʻahaʻa haʻahaʻa HPMC: E hoʻoheheʻeʻia a iʻole nā soltens ma nā haʻahaʻa haʻahaʻa, a hoʻomaka paha e hoʻomaka i ka pyrolyze a iʻole e hoʻomaka i ka pyrolyze°C.
ʻO ka molecular High Light Mopmc: HPMC POLYSMS me nā kaupaona kiʻekiʻe e koi ai i nā kaulahao kiʻekiʻe, a hoʻomaka pinepine ma waena o 250°C a me 300°C.
Nā mea e hoʻopilikia ai i keʻano me ka hpmc
Molecular paona ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa e pili ana i ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa,ʻoiai ke kiʻekiʻe o ke kaupaona kiʻekiʻe e alakaʻi i ke kiʻekiʻe kiʻekiʻe.
ʻO ke kiʻekiʻe o ke hoʻololi: ke kiʻekiʻe o ka hydroxyprocklation (ʻo ia keʻano o ka hoʻohuiʻana o ka mydroxyproxt i ka mollule) o ka molmc Maʻamau, kiʻekiʻe kiʻekiʻe ke kiʻekiʻe o ke kahe koko i ka maʻalahi o HPMC a hōʻemi i kānaʻano meʻeʻana.
ʻO nā meaʻona nui: he mea e like me ka wai wai-wai, ua hoʻopilikiaʻia ka manaʻo o ka HPMC o kāna mau wahi ākea. ʻO HPMC me kahiʻike nui kiʻekiʻe e hiki i keʻano he hydration a iʻole ka hoʻokaʻawaleʻana i ka hoʻokaʻawaleʻana, e hopena ana i kahi loli ma keʻano o keʻano o keʻano o keʻano o ke aniani.
ʻO ke kūpaʻa a me ka decomposing o ka hpmc
ʻOiaiʻaʻole loaʻa kahi HPMC i kahi manawa paʻaʻole,ʻo kona paʻaʻana i ka hana i keʻano hana nui. Wahi a ka nānāʻana o Thermogravimetric (TGA) i kaʻikepili, hoʻomakaʻo HPMC e hōʻole i ka hoʻohemoʻana i ka mahana o 250°C i ka 300°C. E pili ana i ka mahana Decompos kiko'ī ma ke kaupaonaʻana o ke molena, kiʻekiʻe o ka subsity a me nā mea pilikino a me nā mea hoʻonaninani'ē aʻe o HPMC.
ʻO ka mālamaʻana i nā noi o HPMC
I nā noi,ʻo ka manaʻo Melking a me ka haunaele a me ke kūpaʻaʻana o ka hpmc he mea nui loa. ʻO keʻano, i loko o kaʻoihana hale kūʻai,ʻo HPMC maʻamau hoʻohana pinepineʻia e like me kahi mea no ka capsules, nā mea lawe kiʻi kiʻi, a me nā lawe kiʻi no nā lāʻau lapaʻau i hoʻokuʻuʻia. I kēia mau noi, pono ke kūpaʻa o ka germal e hoʻokō i nā koi e hoʻokō nei, a me ka hoʻomaopopoʻana i keʻano o ka HPMC a me ka Melting point o ke kaʻina hana.
Ma ka hale kūkulu kūkulu, ke hopohopo pinepine neiʻo Freffcelcc®hpmc e like me ka poʻe ulaula ma ka maloʻo maloʻo, nā lole a me nā mea hana. I kēia mau noi,ʻo ka paʻaʻana o ka gental o HPMC e pono ai e lilo i loko o kahi ākea e hōʻoia aiʻaʻole ia e hōʻole i ke kūkuluʻana.
Hpmc, ma kahiʻano polymer,ʻaʻohe mea i paʻa i ka pihi paʻa, akā e hōʻike ana i nā hiʻohiʻona nui a me nā hiʻohiʻona pyolysis i loko o kekahi mauʻano ma waena o kekahi mau kūlana. ʻO keʻano o keʻano o keʻano ma waena o keʻano he 200°C a me 300°C, a me ke kumu e like me ke aniani e like me ka mea nui e like me ke kaumaha molena, ke kiʻekiʻe o ka hydroxtopy, a me nā manaʻo o ka hpmc. Ma nāʻano hana noi likeʻole,ʻike i kēia mau kumulāʻau o nā kumulāʻau no kona hoʻomākaukauʻana a me ka hoʻohanaʻana.
