Ihe mkpuchi mkpuchi mmiri na-ebufe mmiri Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose(HEC) bụ polymer soluble mmiri nke sitere na cellulose, polymer eke dị na osisi. A na-ejikarị ya eme ihe dị ka ihe na-eme ka ọkpụkpụ na-ekpuchi mmiri na-ekpuchi mmiri n'ihi njirimara rheological ya, nkwụsi ike, na ndakọrịta na usoro mmiri. Nke a bụ ilebakwu anya na HEC dị ka ihe na-eme ka ọ dị arọ na mkpuchi mmiri:

Ọrụ na Njirimara:

  1. Thickening: HEC dị irè nke ukwuu n'ịbawanye viscosity nke ngwọta mmiri, gụnyere mkpuchi mmiri. Site n'ịbawanye viscosity, HEC na-eme ka nhazi na nhazi ọkwa nke mkpuchi, na-eme ka ngwa ngwa ha dịkwuo mma, ma na-egbochi nkwụsị ma ọ bụ ntapu.
  2. Omume na-eme ka ọ dị nro: HEC na-egosipụta àgwà na-egbuke egbuke, nke pụtara na viscosity ya na-ebelata n'okpuru nrụgide siri ike (dịka, n'oge ngwa), na-enye ohere maka ngwa dị mfe na ịgbasa mkpuchi. Mgbe e wepụrụ ihe nkedo, viscosity na-agbake ngwa ngwa, na-ejigide ọkpụrụkpụ na nkwụsi ike nke mkpuchi ahụ chọrọ.
  3. Nkwụsi ike: HEC na-enye nkwụsi ike na mkpuchi mmiri na-ekpuchi mmiri site na igbochi nhazi nke pigmenti na ihe ndị ọzọ siri ike. Ọ na-enyere aka ịnọgide na-enwe otu mgbasa nke irighiri ihe n'oge usoro mkpuchi, na-eme ka arụmọrụ na ọdịdị na-agbanwe agbanwe.
  4. Ndakọrịta: HEC dakọtara na ụdị ihe mkpuchi dị iche iche, gụnyere pigmenti, ihe nchacha, ihe nkedo, na ihe mgbakwunye. Ọ naghị emetụta arụmọrụ ma ọ bụ akụrụngwa nke ihe ndị ọzọ na nhazi ahụ.
  5. Njide mmiri: HEC nwere ike imeziwanye ihe njigide mmiri nke mkpuchi, na-ebelata ọnụ ọgụgụ nke evaporation mmiri n'oge ngwa na ọgwụgwọ. Nke a nwere ike ịgbatị oge ọrụ nke mkpuchi ma welie adhesion na mkpụrụ.
  6. Nhazi ihe nkiri: HEC na-enye aka n'ịmepụta otu ihe nkiri na-aga n'ihu na-aga n'ihu n'elu ala ka mkpuchi na-akpọnwụ. Ọ na-enyere aka melite ịdịte aka, adhesion, na akụrụngwa nke ihe nkiri mkpuchi a mịrị amị.

Ngwa:

  1. Ihe mkpuchi ihe owuwu: A na-eji HEC eme ihe n'ọtụtụ ebe na agba mmiri na ihe mkpuchi ụlọ iji chịkwaa viscosity, melite ngwa ngwa, na ịkwalite mmepụta ihe nkiri. Ọ dị mma maka iji ya mee ihe n'ime ime na n'èzí, gụnyere primers, emulsion paints, textured coatings, na ịchọ mma.
  2. Ihe mkpuchi ụlọ ọrụ: A na-eji HEC na mkpuchi ụlọ ọrụ dị iche iche, dị ka mkpuchi ụgbọ ala, mkpuchi osisi, mkpuchi ígwè, na mkpuchi nchebe. Ọ na-enyere aka nweta ihe ndị a chọrọ rheological, ọkpụrụkpụ ihe nkiri, na ọdịdị elu na ngwa ndị a.
  3. Kemịkalụ ihe owuwu: A na-arụ ọrụ HEC na kemịkalụ ihe owuwu, gụnyere mkpuchi mkpuchi mmiri, ihe mkpuchi, adhesives, na grouts tile. Ọ na-enye ndim na nkwụsi ike na usoro ndị a, na-eme ka arụmọrụ na ịrụ ọrụ dịkwuo mma.
  4. Mkpuchi akwụkwọ: N'ime mkpuchi akwụkwọ na ọgwụgwọ elu, a na-eji HEC na-eme ka ihe ndị na-emepụta ihe na-emepụta ihe na-eme ka ọ dịkwuo mma, na-eme ka mma ebipụta, na ịbawanye nkwụsị ink n'elu akwụkwọ.
  5. Ihe mkpuchi akwa: A na-eji HEC eme ihe na akwa akwa akwa ma mechaa na-enye ike, nkwụsị mmiri, na iguzogide wrinkle na akwa akwa. Ọ na-enyere aka ịchịkwa viscosity nke usoro mkpuchi ma hụ na ngwa otu n'ime mkpụrụ akwa akwa.

hydroxyethyl cellulose (HEC) na-eje ozi dị ka onye na-emepụta ihe na-emepụta ihe na-arụ ọrụ nke ọma na mkpuchi mmiri na-ebufe mmiri, na-enye njikwa viscosity, nkwụsi ike, njide mmiri, na ihe mmepụta ihe nkiri dị mkpa iji nweta ọrụ mkpuchi na ọdịdị dị mkpa.
