Polyanionic cellulose, PAC HV & LV
Polyanionic cellulose (PAC) bụ polymer bara ụba ejiri rụọ ọrụ dị iche iche, gụnyere mkpọ mmanụ, ọgwụ, ihe owuwu, na nri. PAC dị na akara ule viscosity dị iche iche, gụnyere viscosity dị elu (HV) na viscosity dị ala (LV), nke ọ bụla nwere ngwa na akụrụngwa:
- Polyanionic Cellulose (PAC):
- PAC bụ mkpụrụ ndụ cellulose nwere soluble mmiri sitere na cellulose eke sitere na mgbanwe kemịkalụ, nke na-abụkarị site na iwebata otu carboxymethyl n'ime ọkpụkpụ azụ cellulose.
- A na-eji ya eme ihe n'ọtụtụ ebe dị ka onye na-agbanwe rheology, viscosifier, na onye na-ahụ maka njikwa ọnwụ mmiri na sistemu mmiri.
- PAC na-akwalite akụrụngwa mmiri dị ka viscosity, nkwusioru nke ihe siri ike, na njikwa mfu mmiri na ngwa dị iche iche.
- PAC HV (Elu viscosity):
- PAC HV bụ ọkwa nke cellulose polyanionic nwere nnukwu viscosity.
- A na-eji ya na-egwupụta mmiri mmiri maka nchọpụta mmanụ na gas iji nye nnukwu viscosity na njikwa mfu mmiri dị mma.
- PAC HV bara uru karịsịa n'ọnọdụ mgbapu mmiri na-ama aka ebe idowe nkwụsi ike nke olulu mmiri na ibu ikike nke mkpọpu mkpọpu dị oke mkpa.
- PAC LV (Obere viscosity):
- PAC LV bụ ọkwa nke cellulose polyanionic nwere obere viscosity.
- A na-ejikwa ya na-egwupụta mmiri mana a na-ahọrọ ya mgbe achọrọ obere viscosity na njikwa mfu mmiri.
- PAC LV na-enye viscosification na njikwa njikwa mmiri mmiri ka ọ na-ejigide viscosity dị ala ma e jiri ya tụnyere PAC HV.
Ngwa:
- Ngwunye mmanụ na gas: PAC HV na LV 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 cimentious dị ka grouts, slurries, na mortars eji eme ngwa ihe owuwu.
- Pharmaceuticals: Ma PAC HV na LV nwere ike na-eje ozi dị ka ndị na-ekekọta, disintegrants, na ndị ọrụ mwepụta na-achịkwa na mbadamba na capsule usoro na ọgwụ.
Na nchịkọta, polyanionic cellulose (PAC) na ma elu viscosity (PAC HV) na obere viscosity (PAC LV) akara ule na-arụ ọrụ dị oke mkpa na ụlọ ọrụ dị iche iche, gụnyere ịkụ ala mmanụ, ihe owuwu, na ọgwụ, na-enye njikwa rheological, mgbanwe viscosity, na mmiri mmiri. Njirimara njikwa ọnwụ. Nhọrọ nke ọkwa PAC dabere na ngwa achọrọ na njirimara arụmọrụ achọrọ.
