Kedu ihe bụ HEMC?

Hydroxyethyl Methylcellulose (HEMC) bụ ihe nrụpụta cellulose ether nke a na-ejikarị dị ka ihe na-eme ka ọ sie ike, stabilizer, na mgbakwunye mmiri na ụlọ ọrụ dị iche iche, karịsịa na ihe owuwu, ọgwụ na ngwaahịa nlekọta onwe onye. Dị ka Hydroxypropyl Methylcellulose (HPMC), HEMC na-arụ ọrụ site n'ịgwọ cellulose na ethylene oxide na methyl chloride, na-eme ka ngwakọta nwere ma hydroxyethyl na methyl otu jikọtara na ọkpụkpụ azụ cellulose.

HEMC na-ekerịta ọtụtụ akụrụngwa na HPMC, gụnyere:

1. Njide mmiri: HEMC nwere ikike ịmịnye na idobe mmiri, na-eme ka ọ baa uru na ihe ndị dị na cimenti dị ka ngwa agha na tile adhesives iji gbochie ihicha oge na-arụ ọrụ.
2. Thickening: Ọ nwere ike ịbawanye viscosity nke usoro mmiri mmiri, nke bara uru na ngwa ndị dị ka agba, mkpuchi, na ngwaahịa nlekọta onwe onye iji nweta nkwekọ achọrọ.
3. Nkwụsi ike: HEMC na-enyere aka ịkwado emulsions na nkwusioru, na-egbochi nkewa nke oge na ịnọgide na-enwe otu ụdị ngwaahịa.
4. Nhazi ihe nkiri: Dị ka HPMC, HEMC nwere ike ịmepụta ihe nkiri dị mkpa mgbe etinyere ya n'elu, na-enye nchebe ma na-eme ka adhesion dịkwuo elu.
5. Ngwongwo na-eme ka ọ dị mma: Ọ nwere ike imeziwanye njirimara eruba nke usoro nhazi, na-eme ka nhazi na ngwa ngwa.

A na-ahọrọ HEMC karịa HPMC na ụfọdụ ngwa n'ihi obere viscosity ya na mma solubility na mmiri oyi. Agbanyeghị, nhọrọ n'etiti HEMC na HPMC dabere n'ụdị chọrọ nhazi yana njirisi arụmọrụ.

Na nchịkọta, HEMC bụ ihe na-emepụta cellulose ether dị iche iche nke nwere ọtụtụ ngwa dị iche iche na ụlọ ọrụ dị iche iche, ebe a na-eji ihe onwunwe ya dị ka ihe na-esi ísì ụtọ, ihe nkwụsịtụ, na onye na-ejigide mmiri.
