Hydroxyethyl cellulose (HEC) bụ ihe mgbakwunye a na-ejikarị na ụlọ ọrụ na-egwupụta mmanụ, ebe ọ na-arụ ọrụ dị iche iche na nhazi mmiri mmiri. Usoro ndị a, nke a makwaara dị ka apịtị igwu mmiri, na-ekere òkè dị oke mkpa n'ịkwado usoro ịkụ ihe site na ime ka mmiri dị jụụ na ịgbanye mmanụ a na-egwupụta ihe, na-ebu mkpụkpụ n'elu elu, na-eme ka ọ kwụsie ike na olulu mmiri. Nke a bụ nkọwa nke ngwa, ọrụ, na ntụle nke HEC na mkpọpu mmanụ:

1. Okwu Mmalite nke Hydroxyethyl Cellulose (HEC) na mmanụ ụgbọala

1.1 Nkọwa na isi mmalite

Hydroxyethyl cellulose bụ polima cellulose gbanwetụrụ site na iji ethylene oxide meghachi omume cellulose. A na-enwetakarị ya site na osisi pulp ma ọ bụ owu ma na-edozi ya iji mepụta ihe na-esi na mmiri na-agbaze, viscosifying ihe.

1.2 Onye nnọchi anya Viscosifying na mmiri mmiri

A na-eji HEC na-egwupụta mmiri iji dozie ma jikwaa viscosity ha. Nke a dị oke mkpa maka idowe nrụgide hydraulic dị mkpa n'ime olulu mmiri na ịhụ na ebuga osisi nke ọma na-aga n'elu.

2. Ọrụ nke Hydroxyethyl Cellulose n'ime mmiri na-egwupụta mmanụ

2.1 Njikwa viscosity

HEC na-arụ ọrụ dị ka rheology modifier, na-enye njikwa viscosity nke mmiri mmiri na-egwupụta ihe. Ikike imezi viscosity dị oke mkpa maka imeziwanye ihe na-asọpụta nke mmiri n'okpuru ọnọdụ mkpọpu dị iche iche.

2.2 Nkwụsị mbelata

N'ebe a na-egwupụta ihe, a na-emepụta osisi nkume, ọ dịkwa mkpa ka a kwụsịtụ osisi ndị a n'ime mmiri na-egwupụta ihe iji mee ka ha wepụ ya na olulu mmiri. HEC na-enyere aka ịnọgide na-enwe nkwusioru siri ike nke cuttings.

2.3 Nhicha oghere

Nhicha oghere dị mma dị mkpa maka usoro mkpọpu mmiri. HEC na-enye aka n'ikike nke mmiri na-ebu na ibufe mbepụ n'elu, na-egbochi nchịkọta n'ime olulu mmiri ma na-akwalite ọrụ ịkụ ala nke ọma.

2.4 Okpomọkụ kwụsie ike

HEC na-egosipụta nkwụsi ike nke okpomọkụ dị mma, na-eme ka ọ dị mma maka iji mmiri na-egwupụta mmiri nke nwere ike izute ọnọdụ okpomọkụ dị iche iche n'oge usoro nhazi.

3. Ngwa dị na mmiri mmiri na-egwupụta mmanụ

3.1 Mmiri mmiri na-egwu mmiri

A na-ejikarị HEC eme ihe na mmiri mmiri na-egwupụta mmiri, na-enye njikwa viscosity, nkwụsị nkwụsị, na nkwụsi ike. Ọ na-eme ka arụ ọrụ zuru oke nke apịtị na-adabere na mmiri na gburugburu ebe igwu mmiri dị iche iche.

3.2 Mgbochi Shale

HEC nwere ike inye aka na mgbochi shale site na ịmepụta ihe mgbochi na mgbidi olulu mmiri. Nke a na-enyere aka igbochi ọzịza na mgbakasị nke usoro shale, na-ejigide nkwụsi ike nke ọma.

3.3 Njikwa okirikiri furu efu

N'ịrụ ọrụ ịkụgharị ebe mmiri na-efunahụ na nhazi ahụ bụ nchegbu, HEC nwere ike ịgụnye na nhazi ahụ iji nyere aka ịchịkwa mgbasa ozi na-efunahụ, hụ na mmiri mmiri na-agbapụta na-anọgide na olulu mmiri.

4. Ntụle na ịkpachara anya

4.1 itinye uche

Ekwesịrị iji nlezianya chịkwaa nleba anya nke HEC n'ime mmiri na-egwupụta mmiri iji nweta akụrụngwa rheological chọrọ na-enweghị ime ka oke oke ma ọ bụ na-emetụta njirimara mmiri ndị ọzọ.

4.2 ndakọrịta

Ndakọrịta na ihe mgbakwunye mmiri na-egwupụta ihe ndị ọzọ dị oke mkpa. Ekwesịrị iji nlezianya tụlee usoro ahụ dum iji gbochie okwu ndị dị ka flocculation ma ọ bụ belata irè.

4.3 Njikwa nzacha mmiri

Ọ bụ ezie na HEC nwere ike inye aka na njikwa nkwụsị nke mmiri, ihe mgbakwunye ndị ọzọ nwekwara ike ịdị mkpa iji dozie nsogbu ụkọ mmiri dị iche iche ma nọgide na-achịkwa nchịkwa.

5. Nkwubi okwu

Hydroxyethyl cellulose na-arụ ọrụ dị oke mkpa n'ịrụ ọrụ ngwu mmanụ site n'itinye aka na ịdị irè na nkwụsi ike nke mmiri mmiri. Dị ka onye na-ahụ maka viscosifying, ọ na-enyere aka ịchịkwa ihe ndị na-emepụta mmiri, kwụsịtụ igbutu, na ịnọgide na-enwe nkwụsi ike nke ọma. Ndị na-emepụta ihe kwesịrị iji nlezianya tụlee ntinye uche, ndakọrịta, na nhazi n'ozuzu iji hụ na HEC na-eme ka uru ya dịkwuo elu na ngwa ntinye mmanụ.
