Poly Anionic cellulose, PAC-LV, PAC-HV

Poly anionic cellulose (PAC) bụ polymer soluble mmiri nke ewepụtara na cellulose ma gbanwee ya na otu carboxymethyl. A na-eji ya eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere igwu mmanụ, ihe owuwu, ọgwụ na nri. PAC dị na ọkwa viscosity dị iche iche, yana PAC-LV (Low viscosity) na PAC-HV (High Viscosity) bụ ụdị abụọ a na-ahụkarị. Nke a bụ ndakpọ nke ọ bụla:

1. Poly anionic Cellulose (PAC):
   • PAC bụ ihe nrụpụta cellulose nke na-enye akụrụngwa rheological na ngwọta mmiri.
   • A na-eji ya dị ka viscosifier, onye na-ahụ maka njikwa ihe na-efu mmiri, na rheology modifier n'ọtụtụ ngwa.
   • PAC na-arụ ọrụ nke ọma n'ịchịkwa akụrụngwa mmiri dị ka viscosity, nkwusioru nke ihe siri ike, na mfu mmiri, na-eme ka ọ baa uru na usoro mmepụta ihe dị iche iche.
2. PAC-LV (Viscosity dị ala):
   • PAC-LV bụ ọkwa nke cellulose polyanionic nwere obere viscosity.
   • A na-ejikarị ya mgbe achọrọ viscosity na-agafeghị oke na njikwa mfu mmiri na ngwa dị ka mkpọpu mmanụ, ihe owuwu, na ọgwụ.
   • PAC-LV na-enye viscosification na njikwa njikwa mmiri mmiri ka ọ na-ejigide viscosity dị ala ma e jiri ya tụnyere PAC-HV.
3. PAC-HV (Elu viscosity):
   • PAC-HV bụ ọkwa nke cellulose polyanionic nwere nnukwu viscosity.
   • A na-eji ya eme ihe mgbe achọrọ nnukwu viscosity na njikwa mfu mmiri dị mma, ọkachasị na-achọ ngwa dị ka mkpọ mmanụ na gas.
   • PAC-HV na-arụ ọrụ nke ọma n'ịkwado nkwụsi ike nke olulu mmiri, na-ebu ikike maka igbutu olulu, na ịchịkwa mfu mmiri na ọnọdụ mgbapu mmiri siri ike.

Ngwa:

• Ngwunye mmanụ na gas: Ma PAC-LV na PAC-HV bụ ihe mgbakwunye dị mkpa na mmiri mmiri na-egwupụta mmiri, na-enye aka na njikwa viscosity, njikwa mfu mmiri, na mgbanwe rheology.
• Ihe owuwu: Enwere ike iji PAC-LV dị ka onye na-ebu ibu na onye na-ejigide mmiri n'ụdị cementitious dị ka grouts, slurries, na ngwa agha ndị a na-eji eme ihe na-ewu ụlọ.
• Pharmaceuticals: PAC-LV na PAC-HV nwere ike na-eje ozi dị ka ihe na-ekekọta, disintegrants, na ndị na-achịkwa-wepụta na mbadamba na capsule formulations na ọgwụ.
• Ụlọ ọrụ nri: A na-eji PAC eme ihe dị ka ihe na-agbapụta, stabilizer, na emulsifier na ngwaahịa nri, na-enye udidi na imeziwanye nkwụsi ike ndụ.

Na nchịkọta, polyanionic cellulose na ma obere viscosity (PAC-LV) na elu viscosity (PAC-HV) akara ule na-arụ ọrụ dị mkpa na ụlọ ọrụ dị iche iche, na-enye njikwa rheological, ngbanwe viscosity, na njikwa ọnwụ mmiri nke ahaziri maka ngwa achọrọ.
