Mmetụta Hydroxyethyl Cellulose na mkpuchi mmiri

Hydroxyethyl cellulose (HEC)bụ ihe mgbakwunye a na-ejikarị eme ihe na mkpuchi mmiri n'ihi ngbanwe ya na ịdị irè ya n'ịkwalite ihe dị iche iche.

1. Ngbanwe Rheology:

A na-ejikarị HEC arụ ọrụ dị ka ihe mgbanwe rheology na mkpuchi mmiri. Site n'ịgbanwe ntinye nke HEC, ọ ga-ekwe omume ịchịkwa viscosity na omume na-asọ oyi nke ihe mkpuchi. Nke a dị mkpa maka ngwa dị ka brushability, sprayability, na mkpuchi mkpuchi. HEC na-enye omume pseudoplastic na mkpuchi, nke pụtara na viscosity na-ebelata n'okpuru shear, na-eme ka ngwa ngwa, na-ejigide nguzogide sag dị mma ozugbo ewepụrụ ike ịkpụ.

2. Thixotropy:

Thixotropy bụ ihe ọzọ dị mkpa na mkpuchi mkpuchi, na-ezo aka na omume ngbanwe nke shear thinning. HEC na-enye ihe ndị dị na thixotropic na mkpuchi mmiri, na-enye ha ohere ka ha dị nro n'okpuru mmetụta nke shear n'oge a na-etinye ya, na-eme ka ọ gbasaa nke ọma, wee na-agbatị n'elu guzoro ọtọ, nke na-egbochi nkwụsị na ntanye n'elu elu.

3. Nkwụsi ike:

Nkwụsi ike bụ akụkụ dị oke mkpa nke mkpuchi mmiri, n'ihi na ha ga-anọgide na-adị n'otu n'oge nchekwa na ngwa. HEC na-enye aka na nkwụsi ike nke mkpuchi site na igbochi nhazi pigmenti na nkewa nke oge. Mmetụta ya siri ike na-enyere aka kwụsịtụ ihe ndị siri ike n'otu oge na matrix mkpuchi, na-eme ka arụmọrụ na-agbanwe agbanwe n'oge.

4. Nhazi ihe nkiri:

HEC nwere ike imetụta usoro mmepụta ihe nkiri na mkpuchi mmiri. Ọ na-arụ ọrụ dị ka ihe enyemaka na-emepụta ihe nkiri, na-eme ka nchịkọta nke ihe ndị dị na polymer dị mma n'oge ihicha. Nke a na-eme ka e guzobe ihe nkiri na-aga n'ihu, nke nwere otu ihe na-eme ka ọ dịkwuo mma na ntinye. Ọzọkwa, HEC nwere ike ibelata ọchịchọ nke mkpuchi ịgbawa ma ọ bụ ọnya mgbe akpọnwụsịrị site n'ịkwalite imepụta ihe nkiri kwesịrị ekwesị.

5. Njide mmiri:

Ihe mkpuchi mmiri na-enwekarị ihe ndị na-agbanwe agbanwe nke na-ekpochapụ n'oge ihicha, na-eduga n'ibelata na ntụpọ nwere ike na ihe nkiri mkpuchi. HEC na-enyere aka idowe mmiri n'ime ihe mkpuchi mkpuchi, na-ebelata usoro ihicha na ịkwalite evaporation otu. Nke a na-akwalite iguzosi ike n'ezi ihe nkiri, na-ebelata mbelata, ma na-ebelata ohere nke ntụpọ dị ka pinholes ma ọ bụ cratering.

6. Adhesion na Njikọta:

Adhesion na njikọta bụ ihe dị mkpa maka ịrụ ọrụ nke mkpuchi. HEC na-eme ka adhesion dịkwuo mma site n'ịkwalite wetting kwesịrị ekwesị na ịgbasa n'elu ala, na-eme ka mmekọrịta chiri anya n'etiti mkpuchi na mkpụrụ. Ọzọkwa, mmetụta ya siri ike na-eme ka njikọ dị n'ime matrix mkpuchi, na-eme ka ihe ndị na-emepụta ihe dị mma dị ka ike nkwụsị na nkwụsị abrasion.

7. ndakọrịta:

HEC na-egosipụta ezigbo ndakọrịta na ụdị mkpuchi mkpuchi dị iche iche, gụnyere acrylics, epoxies, polyurethanes, na alkyds. Enwere ike itinye ya n'ụzọ dị mfe n'ime mkpuchi mmiri na-enweghị ịkpata nkewa nke oge ma ọ bụ nsogbu ndakọrịta. Ngbanwe a na-eme ka HEC bụrụ nhọrọ kachasị mma maka ndị na-emepụta ihe na-achọ ịkwalite arụmọrụ nke mkpuchi ha.

8. Uru gburugburu:

A na-akwado mkpuchi mkpuchi mmiri maka mmetụta gburugburu ebe obibi ha dị ala ma e jiri ya tụnyere ihe ndị ọzọ dabere na mgbaze. HEC na-enye aka n'ịkwado gburugburu ebe obibi site n'ime ka ịmepụta ihe mkpuchi na-ebelata ọkwa nke ogige organic na-agbanwe agbanwe (VOCs). Nke a na-enyere ndị na-emepụta ihe mkpuchi aka irube isi n'usoro iwu ma mezuo ọchịchọ ndị ahịa maka ngwaahịa enyi na enyi.

hydroxyethyl cellulosena-enye ọtụtụ uru na mkpuchi mmiri, gụnyere mgbanwe rheology, thixotropy, nkwụsi ike, nhazi ihe nkiri, njide mmiri, nchikota, njikọta, ndakọrịta, na nkwado gburugburu ebe obibi. Ngwongwo ya dị iche iche na-eme ka ọ bụrụ ihe mgbakwunye bara uru maka imezu njirimara arụmọrụ achọrọ na mkpuchi mmiri n'ofe ngwa dị iche iche.
