Ngwa ụlọ ọrụ akọwapụtara nke HEC na mpaghara mkpuchi

HEC (hydroxyethyl cellulose)a na-eji ya eme ihe n'ọtụtụ ebe na mkpuchi n'ihi na ọ na-eme ka ọ dị mma, na-emepụta ihe nkiri, moisturizing na dispersing properties.

1. Ọkpụkpụ
A na-ejikarị HEC eme ihe dị ka ihe mkpuchi maka mmiri na-ekpuchi mmiri, nke nwere ike ịbawanye viscosity nke mkpuchi nke ọma ma mee ka mkpuchi dị mfe ijikwa n'oge usoro mkpuchi. N'ihi na HEC bụ mmiri soluble, ọ nwere ike inye mmetụta dị oke mkpa na ntinye dị ala, na-enyere mkpuchi ahụ aka ịnọgide na-enwe ihe ndị dị mma nke rheological. Nke a dị mkpa karịsịa maka ngwa ndị dị ka spraying na brushing iji gbochie agba ka ọ ghara ịda mbà n'oge ngwa.

2. Mepụta ihe nkiri mkpuchi edo
HEC nwere ọmarịcha ihe na-emepụta ihe nkiri ma nwee ike ịmepụta ihe nkiri mkpuchi edo na nke dị nro n'oge usoro ihicha. Njirimara a na-eme ka HEC na-ejikarị eme ihe na mkpuchi mmiri, dị ka mgbidi mgbidi na mkpuchi osisi. HEC na-enyere aka melite adhesion na mmiri na-eguzogide ihe nkiri mkpuchi, si otú ahụ na-eme ka ịdịte aka na ihe nchebe nke mkpuchi ahụ dịkwuo mma.

3. Njirimara moisturize
N'oge usoro ihicha nke agba,HECnwere ike ijigide mmiri dị na agba nke ọma, si otú a na-ezere mgbawa na peeling nke ihicha ngwa ngwa kpatara. Ngwongwo a na-ekpo ọkụ dị mkpa karịsịa maka mkpuchi mmiri na-adabere na mmiri n'ihi na ọ na-agbatị oge oghere nke mkpuchi ahụ, na-enye onye na-achọ ihe oge iji tinye.

4. Mma rheological Njirimara
HEC nwere ike melite rheological Njirimara nke mkpuchi ka ha na-egosipụta dị iche iche viscosities n'okpuru dị iche iche shiee ọnọdụ. N'okpuru ọnọdụ dị ala, HEC na-enye nnukwu viscosity iji nọgide na-enwe nkwụsi ike mkpuchi, ebe n'okpuru ọnọdụ dị elu, viscosity na-ebelata iji kwado mkpuchi. Ngwongwo a na-akpụ akpụ na-eme ka agba ahụ dịkwuo mmiri n'oge ịgbasa na mkpuchi mpịakọta, na-eme ka ọ dị mfe iji nweta ọbụna mkpuchi.

5. na-ekesa
HEC na-arụkwa ọrụ dị ka onye na-ekesa iji nyere aka gbasaa pigmenti na ihe mkpuchi na mkpuchi. Site n'ịbawanye mgbasa nke pigmenti na ihe ndị na-emepụta ihe na mkpuchi, HEC nwere ike imeziwanye agba agba na-ezochi ike nke mkpuchi. Nke a dị oke mkpa n'ịmepụta ngwaahịa agba dị elu, karịsịa na ngwa agba nke chọrọ otu agba na nnukwu gloss.

6. Njirimara nchedo gburugburu ebe obibi
Ka iwu gburugburu ebe obibi na-esiwanye ike, ọchịchọ nke mkpuchi mmiri na-anọgide na-abawanye. Dị ka polymer sitere n'okike, ihe ndị na-emepụta HEC na-emegharị na gburugburu ebe obibi, ọ pụkwara ibelata ntọhapụ nke ogige organic na-agbanwe agbanwe (VOC) mgbe ejiri ya na mkpuchi, na-agbaso ihe nchebe gburugburu ebe obibi nke ụlọ ọrụ mkpuchi nke oge a.

7. Ihe atụ ngwa
N'ime ngwa bara uru,HECa na-eji ya eme ihe n'ọtụtụ ebe na mkpuchi ụlọ, mkpuchi ụlọ ọrụ, mkpuchi osisi, mkpuchi ụgbọ ala na mpaghara ndị ọzọ. Dịka ọmụmaatụ, na mkpuchi ihe owuwu ụlọ, HEC nwere ike imeziwanye ihe mgbochi na ihu igwe nke mkpuchi; na mkpuchi osisi, HEC nwere ike imeziwanye gloss ma na-eyi nguzogide ihe nkiri mkpuchi.

Ngwa nke HEC na ụlọ ọrụ mkpuchi na-egosipụta n'ụzọ zuru ezu njirimara anụ ahụ na kemịkal ya dị mma. Dị ka a thickener, film mbụ na dispersant, HEC nwere ike budata melite arụmọrụ na àgwà nke coatings. Ka ụlọ ọrụ mkpuchi na-aga n'ihu na-agbaso nchebe gburugburu ebe obibi na ịrụ ọrụ dị elu, a na-atụ anya na ahịa ahịa maka HEC ga-anọgide na-eto eto. Site na nyocha miri emi na ntinye ngwa ngwa na HEC, ndị na-emepụta mkpuchi nwere ike ịmepụta ngwaahịa ndị ọzọ na-asọmpi na ahịa.
