Polyanionic cellulose (PAC) bụ ether cellulose ether nke nwere ike ime mmiri nke a kwadebere site na mgbanwe kemịkalụ nke cellulose eke. Ọ bụ cellulose ether dị mkpa na-edozi mmiri. A na-ejikarị ya eme ihe dị ka nnu sodium ya, a na-ejikwa ya na-egwupụta mmanụ, karịsịa olulu mmiri nnu na igwu mmanụ n'ụsọ oké osimiri.

PAC-Ngwa na mmanụ ala

1. Ọrụ nke PAC na CMC na mmanụ mmanụ bụ ndị a:
- Apịtị nwere PAC na CMC nwere ike ime ka mgbidi nke ọma na-eme ka achicha dị nro na nke siri ike na-eme ka ọ dị ala ma belata mmiri ozuzo;
- Mgbe agbakwunyere PAC na CMC n'ime apịtị ahụ, onye na-egwupụta ihe nwere ike nweta ike mbido mbụ dị ala, mee ka apịtị dị mfe ịhapụ gas a na-etinye n'ime ya, ma tụfuo ngwa ngwa n'ime olulu apịtị;

2. PAC na CMC nwere ndị a magburu onwe arụmọrụ na oilfield ngwa:
- ogo dị elu nke nnọchi, ezigbo edo edo edo edo, viscosity dị elu na obere usoro onunu ogwu, na-emeziwanye arụmọrụ apịtị nke ọma;
- Ezigbo nguzogide mmiri, nguzogide nnu na nguzogide alkali, dabara maka mmiri ọhụrụ, mmiri mmiri na apịtị mmiri brine jupụtara;
- Achịcha apịtị akpụpụtara dị mma ma kwụsie ike, nke nwere ike mee ka usoro ala dị nro kwụsie ike nke ọma ma gbochie mgbidi ogwe osisi;
- Ọ dabara maka sistemụ apịtị nwere njikwa ọdịnaya siri ike yana oke dịgasị iche iche.
3. Ngwa njirimara nke PAC na CMC na mkpọpu mmanụ:
- Ọ nwere ikike nchịkwa mmiri dị elu, karịsịa ihe na-ebelata mmiri mmiri na-arụ ọrụ nke ọma. Na obere usoro onunu ogwu, ọ nwere ike ịchịkwa mmiri na-efunahụ na ọkwa dị elu na-enweghị emetụta ihe ndị ọzọ nke apịtị;

- Ọ nwere ike ịchịkwa rheology nke apịtị ma nwee ezigbo thixotropy. Ọ dị mma maka apịtị mmiri ọ bụla na mmiri ọhụrụ, mmiri mmiri na brine jupụtara;
- Tụkwasị na nke ahụ, a na-eji PAC dị ka mmiri simenti iji gbochie mmiri ịbanye na pores na mgbaji;
- Igwe mmiri nzacha nke a kwadebere na PAC nwere ezigbo nguzogide 2% KCl (ọ ga-agbakwunye ya mgbe ị na-akwadebe mmiri mmiri nzacha), ezigbo solubility, iji dị mma, enwere ike ịkwadebe ya na saịtị, ngwa ngwa gel na-akpụ ọsọ na ájá siri ike na-ebu ikike.
