Polyanionic Cellulose (PAC)

Polyanionic cellulose (PAC) bụ polymer soluble mmiri nke sitere na cellulose, ihe na-eme n'okike dị na osisi. A na-eji PAC eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ịkụ ala mmanụ, n'ihi njirimara ya pụrụ iche na ntụgharị ya. N'ihe gbasara mkpọpu mmanụ, PAC na-arụ ọtụtụ ọrụ dị mkpa n'ịgba mmiri:

1. Viscosification: A na-ejikarị PAC mee ihe dị ka viscosifier na mmiri mmiri na-egwupụta mmiri. Ọ na-enyere aka ịbawanye viscosity nke mmiri mmiri ahụ, na-eme ka ike ya kwụsịtụ na ibufe mkpuru osisi na ihe ndị ọzọ siri ike n'elu. Nke a na-enyere aka n'ịkwado nkwụsi ike nke olulu mmiri yana igbochi ọdịda oghere.
2. Njikwa Mfu mmiri mmiri: PAC na-etolite achicha nzacha dị gịrịgịrị, nke na-adịghị agwụ agwụ na mgbidi nke olulu mmiri, na-ebelata mfu nke mmiri mmiri n'ime nhazi gburugburu. Nke a na-enyere aka ịnọgide na-eguzosi ike n'ezi ihe nke ọma, na-egbochi mmebi nguzobe, ma na-akwalite ịrụ ọrụ nke mkpọpu ihe.
3. Mgbanwe nke Rheology: PAC na-emetụta omume ịgbasa na njirimara rheological nke mmiri olulu mmiri, na-ebuli nkwusioru nke ihe siri ike na ibelata nhazi. Nke a na-eme ka a mata ịrụ ọrụ nke mmiri na-egwupụta ihe n'okpuru ọnọdụ ala dị iche iche.
4. Nhicha oghere: Site n'ịbawanye viscosity na ibu ikike nke mmiri mmiri na-egwupụta ihe, PAC na-eme ka arụmọrụ dị ọcha nke oghere dị mma, na-eme ka mwepụ nke mkpọpu na ihe mkpofu si na olulu mmiri.
5. Okpomọkụ na salinity kwụsie ike: PAC na-egosipụta oke okpomọkụ na nnabata nnu, na-edobe viscosity ya na njirimara arụmọrụ ya n'ọtụtụ ọnọdụ okpomọkụ na salinities zutere na ọrụ mkpọpu.
6. Enyi na gburugburu ebe obibi: PAC sitere na isi mmalite ihe ọkụkụ na-emegharịgharị ma bụrụkwa ihe na-emebi emebi, na-eme ka ọ bụrụ enyi na gburugburu ebe obibi yana dabara adaba maka iji na mpaghara ebe a na-egwupụta ihe na-emetụta gburugburu ebe obibi.

PAC dị n'ọkwa dị iche iche na nkọwapụta ahaziri dabere n'ihe achọrọ mmiri mmiri na ọnọdụ arụ ọrụ. Usoro njikwa mma na-eme ka nkwekọ na nrube isi n'ụkpụrụ ụlọ ọrụ, gụnyere nkọwapụta API (American Petroleum Institute) maka mgbakwunye mmiri mmiri.

Na nchịkọta, polyanionic cellulose (PAC) bụ ihe mgbakwunye dị mkpa na mmiri mmiri na-egwupụta mmiri maka nchọpụta mmanụ na gas, na-enye viscosification, njikwa ọnwụ mmiri, mgbanwe rheology na ihe ndị ọzọ dị mkpa na-enye aka na-arụ ọrụ nke ọma na nke ọma.
