Gịnị bụ oke ojiji nke hydroxyethyl cellulose?

Hydroxyethyl Cellulose (HEC) bụ ihe a na-ejikarị eme ihe, emulsifier na stabilizer, nke a na-ejikarị eme ihe na mkpuchi, ihe ịchọ mma, ihe ncha, ihe ụlọ na ubi ndị ọzọ. A na-ekpebikarị oke ojiji ya dabere na ọnọdụ ngwa akọwapụtara yana chọrọ nhazi.

1. Ụlọ ọrụ mkpuchi
N'ime ihe mkpuchi mmiri, hydroxyethyl cellulose na-ejikarị eme ihe dị ka onye na-ekpo ọkụ na nkwụsịtụ iji nyere aka dozie viscosity na rheology nke mkpuchi. Ọtụtụ mgbe, oke ojiji bụ 0.1% ruo 2.0% (oke nha). Usoro a kapịrị ọnụ na-adabere n'ụdị mkpuchi, ihe ndị rheological chọrọ na nchikota nke ihe ndị ọzọ.

2. Ihe ịchọ mma na ngwaahịa nlekọta onwe onye
N'ihe ịchọ mma, a na-eji hydroxyethyl cellulose mee ihe dị ka onye na-agba ume na stabilizer iji nyere aka melite nhazi na ngwa ngwa nke ngwaahịa. Oke ojiji a na-ejikarị bụ 0.1% ruo 1.0%. Dịka ọmụmaatụ, na ncha ntutu, ihe nhicha ihu, ude mmiri na gel, HEC nwere ike inye ezigbo aka na nkwụsi ike.

3. Cleaners na detergents
Na ndị na-ehicha mmiri mmiri, a na-eji hydroxyethyl cellulose mee ihe iji dozie viscosity na nkwusioru nke ngwaahịa ahụ ma gbochie mmiri ozuzo nke ihe siri ike. Oke ojiji na-abụkarị 0.2% ruo 1.0%. Ọnụ ego HEC ejiri mee ihe dị iche iche nke ngwaahịa nhicha nwere ike ịdị iche.

4. Ihe owuwu ụlọ
N'ime ihe owuwu ụlọ, dị ka ciment slurry, gypsum, tile adhesives, etc., hydroxyethyl cellulose na-eji dị ka mmiri na-ejigide mmiri na thickener. Ọtụtụ mgbe, oke ojiji bụ 0.1% ruo 0.5%. HEC nwere ike imeziwanye arụmọrụ ihe owuwu nke ihe ahụ, gbatịa oge ọrụ, ma melite ihe onwunwe mgbochi.

5. Ngwa ndị ọzọ
A na-ejikwa hydroxyethyl cellulose eme ihe na mpaghara ndị ọzọ, dị ka nri na ọgwụ. A na-edozi oke ojiji dị ka ngwa achọrọ si dị. Dịka ọmụmaatụ, na ụlọ ọrụ nri, HEC nwere ike iji mee ihe dị ka onye na-agba ume, stabilizer na emulsifier, na ojiji ya na-adịkarị ala.

Mkpachapụ anya
Mgbe ị na-eji hydroxyethyl cellulose, ị kwesịrị ịṅa ntị na isi ihe ndị a:

Usoro mgbasa: A na-emetụta solubility nke HEC site na okpomọkụ, uru pH na ọnọdụ mkpali. Ọ na-adịkarị mkpa iji nwayọọ tinye ya na mmiri ma kpalie ya nke ọma.
Ndakọrịta usoro: Ngwakọta usoro dị iche iche nwere ike imetụta arụmọrụ nke HEC, yabụ achọrọ nnwale ndakọrịta n'oge usoro mmepe nhazi.
Njikwa viscosity: Dị ka mkpa nke ngwaahịa ikpeazụ si dị, họrọ ụdị HEC kwesịrị ekwesị na usoro ọgwụgwọ iji nweta viscosity achọrọ.
Oke ojiji nke hydroxyethyl cellulose bụ ihe ngbanwe na-agbanwe agbanwe nke achọrọ ka emezi ya dabere na ngwa na usoro akọwapụtara. Ịghọta arụmọrụ nke HEC na ngwa dị iche iche nwere ike inyere aka ịkwalite arụmọrụ ngwaahịa na ịdị mma.
