Mmepe na Ngwa nke Cellulose Ether

Cellulose ethers enweela mmepe dị ukwuu wee chọta ngwa ngwa n'ofe ụlọ ọrụ dị iche iche n'ihi ihe ha pụrụ iche na ọdịdị dị iche iche.Nke a bụ nkọwapụta nke mmepe na ntinye nke cellulose ethers:

1. Mmepe akụkọ ihe mere eme: Mmepe nke cellulose ethers malitere na njedebe narị afọ nke 19, na nchọpụta nke usoro iji gbanwee mkpụrụ ndụ cellulose n'ụzọ kemịkal.Mgbalị ndị mbụ lekwasịrị anya na usoro ntọhapụ iji webata otu hydroxyalkyl, dị ka hydroxypropyl na hydroxyethyl, n'ime ọkpụkpụ azụ cellulose.
2. Mgbanwe kemịkalụ: A na-emepụta ethers cellulose site na mgbanwe kemịkalụ nke cellulose, nke bụ isi site na etherification ma ọ bụ mmeghachi omume esterification.Etherification na-agụnye dochie otu hydroxyl nke cellulose na otu ether, ebe esterification na-eji otu ester dochie ha.Mgbanwe ndị a na-enye ihe dị iche iche na cellulose ethers, dị ka solubility na mmiri ma ọ bụ ihe mgbaze organic, ike imepụta ihe nkiri, na njikwa viscosity.
3. Ụdị cellulose ethers: cellulose ethers nkịtị gụnyere methyl cellulose (MC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), na hydroxypropyl methyl cellulose (HPMC).Ụdị ọ bụla nwere ihe pụrụ iche ma dị mma maka ngwa ngwa.
4. Ngwa na-ewu ihe: A na-eji ethers cellulose eme ihe n'ọtụtụ ebe na ụlọ ọrụ mmepụta ihe dị ka ihe mgbakwunye na ihe simenti, dị ka ngwa agha, grouts, na ngwaahịa gypsum.Ha na-eme ka arụ ọrụ dị mma, njide mmiri, adhesion, na n'ozuzu arụmọrụ nke ihe ndị a.HPMC, ọkachasị, a na-arụ ọrụ nke ukwuu na nrapado tile, ihe nrụnye, na ogige na-ebuli onwe ya.
5. Ngwa dị na Pharmaceuticals: Cellulose ethers na-arụ ọrụ dị oke mkpa na nhazi ọgwụ dịka ndị na-ekekọta, ndị na-ekesa, ndị na-eme ihe nkiri, na ndị na-emegharị viscosity.A na-ejikarị ha eme ihe na mkpuchi mbadamba nkume, usoro ntọhapụ a na-achịkwa, nkwusioru, na ngwọta anya n'ihi na ha biocompatibility, nkwụsi ike, na profaịlụ nchekwa.
6. Ngwa dị na nri na nlekọta onwe onye: N'ụlọ ọrụ nri, a na-eji cellulose ethers eme ihe dị ka ndị na-esi ísì ụtọ, ihe nkwụnye na emulsifiers n'ọtụtụ ngwaahịa, gụnyere sauces, uwe, ngwaahịa mmiri ara ehi, na ngwaahịa esi nri.N'ime ngwaahịa nlekọta onwe onye, ​​a na-ahụ ha na ntacha eze, ncha ntutu, lotions, na ihe ịchọ mma maka ihe na-eme ka ha sie ike na mmiri.
7. Ihe gbasara gburugburu ebe obibi: A na-ewerekarị cellulose ethers dị ka ihe nchekwa na gburugburu ebe obibi.Ha bụ ihe na-emebi emebi, na-emegharịghachi, na ndị na-adịghị egbu egbu, na-eme ka ha bụrụ ihe ndị ọzọ mara mma na polymer synthetic n'ọtụtụ ngwa.
8. Nnyocha na ihe ọhụrụ na-aga n'ihu: Nchọpụta na cellulose ethers na-aga n'ihu, na-elekwasị anya na ịmepụta ihe ọhụrụ na-emepụta ihe na-eme ka ọ dịkwuo mma, dị ka mmetụta okpomọkụ, mkpali na-anabataghachi, na bioactivity.Na mgbakwunye, a na-eme mbọ iji kwalite usoro mmepụta, melite nkwado, na ịchọpụta ngwa ọhụrụ na mpaghara na-apụta.

cellulose ethers na-anọchi anya klaasị polymers nwere ọtụtụ ngwa n'ofe ụlọ ọrụ.Emebela mmepe na ntinye ha site na nyocha na-aga n'ihu, ọganihu teknụzụ, na mkpa maka ihe na-adịgide adịgide ma dị irè na mpaghara dị iche iche.
