Polyanionic cellulose LV HV

Polyanionic cellulose (PAC) ndi polima yosungunuka m'madzi yomwe imachokera ku cellulose. Amagwiritsidwa ntchito kwambiri m'makampani amafuta ndi gasi ngati chowonjezera chamadzimadzi, komwe amagwiritsidwa ntchito kuwongolera kutayika kwamadzimadzi, kukulitsa kukhuthala, ndikuwongolera kuletsa kwa shale. PAC imapezeka m'makalasi osiyanasiyana, ndi magawo osiyanasiyana olowa m'malo ndi kulemera kwa maselo. Magiredi awiri odziwika a PAC ndi low viscosity (LV) ndi high viscosity (HV) PAC.

PAC LV ali ndi otsika maselo kulemera ndi otsika digiri m'malo. Amagwiritsidwa ntchito ngati njira yowongolera kusefera komanso ngati rheology modifier mumadzi akubowola. LV-PAC ili ndi kusungunuka kwabwino m'madzi ndipo imagwira ntchito motsika kwambiri. Amagwiritsidwanso ntchito ngati viscosifier mu slurries simenti komanso ngati stabilizer mu emulsions.

PAC HV, kumbali ina, ili ndi kulemera kwakukulu kwa mamolekyu ndi malo apamwamba kuposa LV-PAC. Amagwiritsidwa ntchito ngati viscosifier woyambira komanso wowongolera kutaya kwamadzi mumadzi akubowola. HV-PAC itha kugwiritsidwanso ntchito ngati viscosifier yachiwiri kuphatikiza ma polima ena. Ili ndi kulolerana kwakukulu kwa mchere ndi kutentha, ndipo imakhala yogwira mtima kwambiri.

Onse LV-PAC ndi HV-PAC ndi polyanionic, kutanthauza kuti ali ndi mlandu wolakwika. Mlanduwu umawapangitsa kukhala ogwira mtima pakuwongolera kutayika kwamadzimadzi popanga keke yosefera pachitsime. Mlandu wolakwika umawapangitsanso kuti azitha kuletsa shale hydration ndi kubalalitsidwa. PAC imathanso kupititsa patsogolo kukhazikika kwabwino poletsa kusamuka kwa chindapusa ndi tinthu tadongo.

Pomaliza, polyanionic cellulose (PAC) ndi polima yosunthika yomwe imagwiritsidwa ntchito m'makampani amafuta ndi gasi ngati chowonjezera chamadzimadzi. LV-PAC ndi HV-PAC ndi magulu awiri wamba a PAC omwe amagwiritsidwa ntchito pazolinga zosiyanasiyana. LV-PAC imagwiritsidwa ntchito ngati chowongolera kusefera komanso ngati rheology modifier, pomwe HV-PAC imagwiritsidwa ntchito ngati chowonera chachikulu komanso chowongolera kutaya kwamadzi. Magiredi onse a PAC ndi a polyanionic komanso othandiza pakuwongolera kutayika kwamadzimadzi komanso kuletsa ma shale hydration ndi kubalalitsidwa.
