Ihe ndị na-emetụta arụmọrụ nke Cellulose Ether

Arụ ọrụ nke cellulose ethers, dị ka hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), na carboxymethyl cellulose (CMC), na ngwa dị iche iche na-emetụta ọtụtụ ihe.Ịghọta ihe ndị a dị oké mkpa maka ịkwalite arụmọrụ cellulose ethers na nhazi ndị a kapịrị ọnụ.Nke a bụ ụfọdụ isi ihe na-emetụta arụmọrụ cellulose ethers:

1. Ọdịdị kemịkalụ: Ọdịdị kemịkal nke cellulose ethers, gụnyere paramita dị ka ogo nnọchi anya (DS), ịdị arọ molekụla, na ụdị ether dị iche iche (dịka, hydroxypropyl, hydroxyethyl, carboxymethyl), na-emetụta njirimara na arụmọrụ ha nke ukwuu.DS dị elu na ịdị arọ molekụla n'ozuzu na-eduga na njigide mmiri ka mma, viscosity, na ike imepụta ihe nkiri.
2. Usoro onunu ogwu: Ọnụ ọgụgụ nke cellulose ether agbakwunyere na nhazi na-arụ ọrụ dị oke mkpa n'ịchọpụta ọrụ ya.Ekwesịrị ikpebi ọkwa usoro ọgwụgwọ kachasị mma dabere na ihe achọrọ nke ngwa ahụ, na-atụle ihe ndị dị ka viscosity chọrọ, njide mmiri, nrapado, na arụ ọrụ.
3. Oke urughuru nha na nkesa: The urughuru size na nkesa nke cellulose ethers emetụta ha dispersibility na uniformity n'ime usoro.Ihe ndị a chụsasịrị nke ọma na-eme ka hydration dị mma na mmekọrịta ya na ihe ndị ọzọ, na-eduga na arụmọrụ ka mma.
4. Usoro ngwakọta: Usoro ngwakọta a na-eji n'oge nkwadebe nke usoro nwere cellulose ethers na-emetụta mgbasa ha na hydration.Usoro ngwakọta kwesịrị ekwesị na-eme ka nkesa otu polymer dị n'ime usoro ahụ, na-eme ka ọ dị irè n'inye ihe ndị a chọrọ.
5. Okpomọkụ na iru mmiri: Ọnọdụ gburugburu ebe obibi, dị ka okpomọkụ na iru mmiri, nwere ike imetụta arụmọrụ cellulose ethers.Okpomọkụ dị elu nwere ike mee ka ọ̀tụ̀tụ̀ mmiri na-ekpo ọkụ na-agbaze ngwa ngwa, ebe okpomọkụ dị ala nwere ike belata usoro ndị a.Ọkwa iru mmiri nwekwara ike imetụta ikike njide mmiri na ịrụ ọrụ nke ethers cellulose.
6. pH na ike ionic: pH na ike ionic nke nhazi nwere ike imetụta solubility na nkwụsi ike nke cellulose ethers.Ha nwekwara ike imetụta mmekọrịta dị n'etiti cellulose ethers na ihe ndị ọzọ, dị ka ciment, aggregates, na mgbakwunye, na-eduga ná mgbanwe na arụmọrụ.
7. Ndakọrịta kemịkalụ: Cellulose ethers kwesịrị ikwekọ na ihe ndị ọzọ dị na nhazi ahụ, dị ka ciment, aggregates, admixtures, na mgbakwunye.Enweghị ndakọrịta ma ọ bụ mmekọrịta ya na ihe ndị ọzọ nwere ike imetụta arụmọrụ yana njirimara nke ngwaahịa ikpeazụ.
8. Ọnọdụ Ngwọta: N'ime ngwa ebe achọrọ ọgwụgwọ, dị ka ihe sitere na ciment, ọnọdụ ọgwụgwọ (dịka ọmụmaatụ, oge ọgwụgwọ, okpomọkụ, iru mmiri) nwere ike imetụta hydration na mmepe nke ike.Ngwọta nke ọma na-eme ka arụmọrụ cellulose ethers dị mma na ngwaahịa a gwọrọ.
9. Ọnọdụ Nchekwa: Ọnọdụ nchekwa kwesịrị ekwesị, gụnyere okpomọkụ, iru mmiri, na ikpughe na ìhè, dị mkpa maka ịnọgide na-enwe ogo na arụmọrụ nke ethers cellulose.Nchekwa na-ezighị ezi nwere ike iduga nbibi, nkwụsị nke ịdị irè, na mgbanwe nke ihe onwunwe.

Site n'ịtụle ihe ndị a na ịkwalite usoro mmepụta ihe, arụmọrụ nke cellulose ethers nwere ike ime ka ọ dịkwuo ngwa ngwa n'ime ụlọ ọrụ dịka ihe owuwu, ụlọ ọgwụ, nri, nlekọta onwe onye, ​​​​na ndị ọzọ.
