Hydroxyethyl cellulose nke anọ

Quaternized hydroxyethyl cellulose (QHEC) bụ ụdị hydroxyethyl cellulose (HEC) gbanwetụrụ nke ejirila ngwakọta ammonium quternary meghachi omume. Ngbanwe a na-agbanwe ihe onwunwe nke HEC ma na-ebute polymer cationic nke nwere ọtụtụ ngwa ngwa, gụnyere na ngwaahịa nlekọta onwe onye, ​​textiles, na mkpuchi akwụkwọ.

Ntughari nke HEC na-agụnye mgbakwunye nke ammonium quaternary na molecule HEC, nke na-ewebata ụgwọ dị mma n'ime polymer. Ngwakọta ammonium quaternary a na-ejikarị eme ihe maka ebumnuche a bụ 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC). Ngwakọta a na-emeghachi omume na ndị otu hydroxyl na molekul HEC, na-ebute molekul QHEC nke ọma.

Otu n'ime ngwa HEC bụ isi bụ na ngwaahịa nlekọta onwe onye, ​​​​dị ka shampoos, conditioners, na ngwaahịa nhazi ntutu. HEC na-enye ihe ndozi dị mma ma na-ewepụ ntutu isi, na-eme ka ọ dị mfe ịgbakọ na ịke. A na-ejikwa HEC dị ka onye na-agbapụta agba na rheology modifier na ngwaahịa ndị a, na-enye udidi mara mma ma na-eme ka arụmọrụ ya dịkwuo elu.

N'ime ngwa textile, a na-eji HEC mee ihe dị ka ihe na-eme ka owu na eriri ndị ọzọ dị n'okike. HEC nwere ike imeziwanye nkwụsi ike na nkwụsị nke abrasion nke ákwà, na-eme ka ha dịkwuo ogologo ma dị mfe ijikwa n'oge usoro mmepụta ihe. HEC nwekwara ike imeziwanye nchikota nke akwa na ihe ndị ọzọ na-emecha na akwa ákwà, na-eme ka agba na-egbuke egbuke ma na-asachapụ ngwa ngwa.

A na-ejikwa HEC na mkpuchi akwụkwọ iji meziwanye nguzogide mmiri na mbipụta akwụkwọ. HEC nwere ike imeziwanye ihe mkpuchi mkpuchi ma belata ntinye mmiri na ink n'ime eriri akwụkwọ, na-eme ka mbipụta dị nkọ ma dị egwu. HEC nwekwara ike inye ọmarịcha elu dị mma na gloss na akwụkwọ, na-eme ka ọdịdị ya dịkwuo mma na ihe ọkụkụ.

Otu n'ime uru dị mkpa nke HEC bụ ọdịdị cationic ya, nke na-eme ka ọ dị irè na nhazi nke nwere ihe ndị na-emepụta anionic. A na-ejikarị surfactants anionic na ngwaahịa nlekọta onwe onye, ​​​​ma ha nwere ike imekọrịta ihe na ndị na-abụghị ionic thickeners, dị ka HEC, ma belata irè ha. HEC, ịbụ cationic, nwere ike ịmepụta mmekọrịta siri ike nke electrostatic na anionic surfactants, na-ebute mmụba na nkwụsi ike ka mma.

Uru ọzọ nke HEC bụ ndakọrịta ya na ọtụtụ ihe ndị ọzọ. Enwere ike iji HEC na ihe ndị ọzọ cationic, anionic, na ndị na-abụghị ionic na-emetụtaghị arụmọrụ ya. Nke a na-eme ka ọ bụrụ ihe dị iche iche nwere ike iji mee ihe n'ọtụtụ nhazi na ngwa.

HEC dị na ọkwa dị iche iche na viscosities, dabere na ngwa ngwa na nhazi chọrọ. A na-enyekarị ya dị ka ntụ ntụ nke enwere ike ịgbasa ngwa ngwa na mmiri ma ọ bụ ihe mgbaze ndị ọzọ. Enwere ike ịnye QHEC dị ka ngwaahịa na-anọpụ iche ma ọ bụ na-ewepụ onwe ya, nke na-ewepụ mkpa maka usoro nkwụsịtụ ọzọ n'oge usoro nhazi.

Na nchịkọta, quaternized hydroxyethyl cellulose bụ ụdị hydroxyethyl cellulose gbanwetụrụ nke ejirila ammonium quaternary meghachi omume. HEC bụ polymer cationic nke nwere ọtụtụ ngwa, gụnyere na ngwaahịa nlekọta onwe onye, ​​akwa akwa, na mkpuchi akwụkwọ. HEC na-enye ihe ndozi dị mma na ihe na-eme ka ọ dịkwuo mma, na-eme ka arụ ọrụ nke anionic surfactants dịkwuo mma, yana dakọtara na ọtụtụ ihe ndị ọzọ. Ntughari na arụmọrụ nke HEC na-eme ka ọ bụrụ ihe bara uru na nhazi na ngwa dị iche iche.
