Ngwa nke Hydroxyethyl Cellulose na mkpuchi
Hydroxyethyl cellulose (HEC)bụ polymer vasatail nke a na-ejikarị n'ọtụtụ ụlọ ọrụ dị iche iche n'ihi njiri mara mma ya, nkwụsi ike, na imepụta ihe nkiri. N'ebe a na-ekpuchi mkpuchi, HEC na-arụ ọrụ dị mkpa n'ịkwalite viscosity, na-emeziwanye ihe rheological, na inye ihe nkiri dị elu.
Okwu mmalite:
Hydroxyethyl cellulose (HEC) bụ ihe na-abụghị ionic, mmiri-soluble polymer nke sitere na cellulose site na mgbanwe kemịkalụ. A na-ejikarị ya eme ihe na ụlọ ọrụ dị iche iche dị ka ọgwụ ọgwụ, nlekọta onwe onye, ihe owuwu, na mkpuchi n'ihi ihe pụrụ iche ya. N'ebe mkpuchi mkpuchi, HEC na-arụ ọrụ dị iche iche, gụnyere ịgba, ịkwado, na inye ihe ndị na-emepụta ihe nkiri. Isiokwu a na-elekwasị anya na ngwa nke HEC na mkpuchi ma nyochaa mmetụta ya na arụmọrụ mkpuchi.
Ngwa nke HEC na mkpuchi:
Ihe na-eme mkpọtụ:
HEC na-eje ozi dị ka ihe na-arụ ọrụ nke ọma na-emepụta ihe na mkpuchi mkpuchi. Site n'ịbawanye viscosity nke ngwọta mkpuchi, HEC na-eme ka nkwụsi ike nke pigmenti na ihe mgbakwunye, na-egbochi nhazi ma ọ bụ syneresis n'oge nchekwa na ngwa. Enwere ike imezi viscosity nke mkpuchi ahụ site n'ịgbanwe ntinye nke HEC, na-enye ohere maka nhazi ahaziri iji mezuo ihe achọrọ ngwa ngwa. Ọzọkwa, HEC na-enye omume pseudoplastic, nke pụtara na ọ na-egosiputa viscosity belatara n'okpuru shear, na-eme ka ngwa ngwa dị mfe na nhazi nke mkpuchi.
Mgbanwe Rheology:
Na mgbakwunye na ndim, HEC na-arụ ọrụ dị ka rheology modifier na mkpuchi mkpuchi. Ọ na-emetụta omume mgbaba nke mkpuchi ahụ, na-emeziwanye ngwa ngwa ya dị ka brushability, sprayability, na roller-coatability. HEC na-enye omume na-akpachapụ anya na mkpuchi ahụ, na-enye ohere maka ngwa dị nro ka ọ na-ejigide viscosity mgbe ewepụrụ ike ịkwa ahụ. Ngwongwo a bara uru karịsịa n'ibelata mgbụsị akwụkwọ mgbe a na-eji mmiri na-efesa na ịhụ na mkpuchi otu n'ime ihe ndị nwere profaịlụ elu dị iche iche.
Onye bụbu ihe nkiri:
HEC na-enye aka n'ịmepụta ihe nkiri na-aga n'ihu na nke edo n'elu ala. Ka ihe mkpuchi ahụ na-akpọnwụ, mkpụrụ ndụ HEC na-ejikọta ọnụ iji mepụta usoro ihe nkiri na-ejikọta ọnụ, na-enye ezigbo mmachi na mkpụrụ ahụ ma na-eme ka ọ dịkwuo ogologo oge nke mkpuchi ahụ. Ihe na-emepụta ihe nkiri nke HEC dị oké mkpa iji nweta njirimara mkpuchi chọrọ dị ka ike, mgbanwe, na nkwụsị ihu igwe. Ọzọkwa, ihe nkiri HEC na-egosipụta ezigbo mmiri na-eguzogide mmiri, na-eme ka ọ dị mma maka mkpuchi mkpuchi na-ekpuchi mmiri ma ọ bụ nnukwu iru mmiri.
Mmetụta HEC na arụmọrụ mkpuchi:
Njikwa viscosity:
HEC na-eme ka njikwa ziri ezi na-achịkwa viscosity nke mkpuchi, na-eme ka usoro kachasị mma na njirimara ọkwa. Nlekọta viscosity kwesịrị ekwesị na-egbochi okwu ndị dị ka ịsagharị, ntapu, ma ọ bụ mkpuchi na-enweghị isi n'oge ngwa, na-eduga n'ịdị mma mkpuchi na mma. Ọzọkwa, omume na-akpụ akpụ nke HEC na-eme ka ngwa ngwa dị mfe na-enweghị imebi arụmọrụ mkpuchi.
Ọkwa na Nguzogide Sag:
Njirimara rheological nke HEC nyere na-enye aka na ọkwa dị mma na nguzogide sag nke mkpuchi. N'oge ntinye akwụkwọ, HEC na-ebelata ọchịchọ nke mkpuchi na-emepụta akara nchara ma ọ bụ ihe nrịbama, na-eme ka ọ dị mma ma dị mma. Na mgbakwunye, HEC na-akwalite omume thixotropic nke mkpuchi, na-egbochi ịsa mmiri ma ọ bụ ntapu n'elu elu kwụ ọtọ, si otú a na-emeziwanye ngwa ngwa yana ibelata mkpofu ihe.
Adhesion:
HEC na-eme ka adhesion nke mkpuchi na ihe dị iche iche dị iche iche, gụnyere ọla, osisi, plastik, na ihe. Ihe na-emepụta ihe nkiri nke HEC na-eme ka njikọ siri ike n'etiti mkpuchi na mkpụrụ ahụ, na-eme ka adhesion na ogologo oge dịkwuo elu. Nke a dị mkpa karịsịa na mkpuchi mpụta nke ekpughere na ọnọdụ gburugburu ebe obibi siri ike, ebe adhesion na-arụ ọrụ dị oke mkpa iji gbochie ọdịda mkpuchi dị ka peeling ma ọ bụ delamination.
Ọganihu na teknụzụ HEC:
Ọganiihu na nso nso a naHECnkà na ụzụ emewo ka e nwee mmepụta nke ihe mmepụta HEC gbanwetụrụ na njirimara arụmọrụ emelitere. Mgbanwe ndị a gụnyere mgbanwe dị na ịdị arọ molekụla, ogo ngbanwe, na nhazi kemịkalụ, na-enye ohere maka azịza ahaziri iji zute ihe achọrọ ngwa ngwa. Ọzọkwa, resea
Mgbalị rch lekwasịrị anya n'ịkwalite nkwado gburugburu ebe obibi nke usoro mmepụta HEC, na-eduga na mpụta nke HEC dabeere na bio nke sitere na isi mmalite ndị a na-emegharịgharị dị ka cellulose sitere na biomass osisi.
Ọnọdụ na-apụta na ngwa HEC na mkpuchi:
Usoro dị mma gburugburu ebe obibi:
Site n'ịgbasi ike na nkwado na ụkpụrụ gburugburu ebe obibi, a na-enwewanye ọchịchọ maka nhazi mkpuchi nke na-eji ihe mgbakwunye eco-friendly dị ka HEC.
