Polyanionic cellulose

Polyanionic cellulose

Polyanionic cellulose (PAC) bụ ihe nrụpụta cellulose na-agbaze mmiri nke na-ahụta ebe niile na ngwa ụlọ ọrụ dị iche iche, ọkachasị na ụlọ ọrụ na-egwupụta mmanụ na gas. Nke a bụ nkọwa nke cellulose polyanionic:

1. Ihe mejupụtara: Polyanionic cellulose sitere na cellulose, polymer eke dị na osisi, site na mgbanwe kemịkalụ. A na-ewebata otu Carboxymethyl n'ime ọkpụkpụ azụ cellulose, na-enye ya ihe onwunwe anionic (na-adịghị mma).

2. Ọrụ:

  • Viscosifier: A na-ejikarị PAC mee ihe dị ka viscosifier na mmiri mmiri na-egwupụta mmiri. Ọ na-enye viscosity na mmiri mmiri ahụ, na-eme ka ike ya kwụsịtụ ma bufee osisi ndị a gbapụrụ agbapu n'elu.
  • Njikwa mkpofu mmiri mmiri: PAC na-etolite achicha nzacha dị gịrịgịrị, nke na-agaghị emebi emebi na mgbidi olulu mmiri, na-ebelata mfu mmiri n'ime nhazi yana idowe nkwụsi ike nke ọma.
  • Rheology Modifier: PAC na-emetụta omume na-asọpụta na ihe njiri mara nke ịkwọ ụgbọ mmiri, na-eme ka nkwusioru nke ihe ndị siri ike na-ebelata ma na-ebelata nhazi.

3. Ngwa:

  • Ngwunye mmanụ na gas: PAC bụ ihe mgbakwunye dị mkpa na mmiri mgbapu mmiri na-eji na nyocha na mmepụta mmanụ na gas. Ọ na-enyere aka ịchịkwa viscosity, mfu mmiri mmiri, na rheology, na-ahụ na arụmọrụ mkpọpu nke ọma na nkwụsi ike nke ọma.
  • Mwube: A na-eji PAC dị ka ihe na-ebu ibu na ihe na-ejigide mmiri n'ụdị cementitious dị ka grouts, slurries, na ngwa agha eji eme ngwa ihe owuwu.
  • Ọgwụ: N'ime usoro ọgwụ, PAC na-eje ozi dị ka onye na-ekekọta, na-agbasasị, na onye na-achịkwa ntọhapụ n'ụdị mbadamba na capsule.

4. Ngwongwo:

  • Mmiri Solubility: PAC na-agbaze ngwa ngwa n'ime mmiri, na-enye ohere maka ntinye dị mfe n'ime sistemu mmiri na-enweghị mkpa maka ihe mgbaze ma ọ bụ ndị na-ekesa.
  • Nkwụsi ike dị elu: PAC na-egosipụta nkwụsi ike dị elu nke okpomọkụ na kemịkalụ, na-ejigide njirimara arụmọrụ ya n'elu oke okpomọkụ na ọnọdụ pH.
  • Ntachi obi nnu: PAC na-egosipụta ezigbo ndakọrịta na ọkwa dị elu nke nnu na brines a na-ezutekarị na gburugburu ebe mmanụ.
  • Biodegradability: PAC sitere na isi mmalite sitere na osisi a na-emegharịgharị ma bụrụ ihe na-emebi emebi, na-eme ka ọ bụrụ enyi na gburugburu ebe obibi.

5. Ogo na nkọwapụta:

  • Ngwaahịa PAC dị n'ọkwa dị iche iche na nkọwapụta ahaziri maka ngwa dị iche iche yana chọrọ ịrụ 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 bụ ihe mgbakwunye na-arụ ọrụ nke ọma na viscosifying, njikwa ọnwụ mmiri, na akụrụngwa rheological, na-eme ka ọ dị mkpa maka ngwa ụlọ ọrụ dị iche iche, karịsịa na ụlọ ọrụ na-egwupụta mmanụ na gas. Ntụkwasị obi ya, arụmọrụ ya na ndakọrịta gburugburu ebe obibi na-enye aka n'iji ya eme ihe na gburugburu ebe mgbapu ihe ịma aka.
