Polyanionic cellulose LV HV

ʻO ka polyanionic cellulose (PAC) he polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose. Hoʻohana nui ʻia ia i ka ʻoihana aila a me ke kinoea ma ke ʻano he mea hoʻohui wai drilling, kahi e hoʻohana ʻia ai e kāohi i ka nalowale o ka wai, hoʻonui i ka viscosity, a hoʻomaikaʻi i ka pale shale. Loaʻa ka PAC i nā māka like ʻole, me nā pae like ʻole o ka hoʻololi ʻana a me ke kaumaha molekala. ʻElua mau māka maʻamau o ka PAC he haʻahaʻa viscosity (LV) a me ka viscosity kiʻekiʻe (HV) PAC.

He haʻahaʻa koʻikoʻi ko PAC LV a he haʻahaʻa haʻahaʻa o ka hoʻololi. Hoʻohana ʻia ia ma ke ʻano he mea hoʻoponopono filtration a ma ke ʻano he rheology modifier i nā wai wili. Loaʻa i ka LV-PAC ka solubility maikaʻi i ka wai a maikaʻi hoʻi i nā haʻahaʻa haʻahaʻa. Hoʻohana ʻia ia ma ke ʻano he viscosifier i nā slurries sima a me kahi stabilizer i nā emulsions.

ʻO ka PAC HV, ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka nui o ke kaumaha molecular a me kahi kiʻekiʻe o ka hoʻololi ʻana ma mua o LV-PAC. Hoʻohana ʻia ʻo ia ma ke ʻano he viscosifier mua a me ka mea hoʻokele hoʻoheheʻe wai i ka wai wili. Hiki ke hoʻohana ʻia ka HV-PAC ma ke ʻano he viscosifier lua i hui pū ʻia me nā polymers ʻē aʻe. Loaʻa iā ia kahi ʻae kiʻekiʻe no ka paʻakai a me ka mahana, a maikaʻi i nā kiʻekiʻe kiʻekiʻe.

ʻO ka LV-PAC a me ka HV-PAC he polyanionic, ʻo ia hoʻi ke lawe nei lākou i ka uku ʻino. Hoʻoikaika kēia uku iā lākou i ke kāohi ʻana i ka nalowale o ka wai ma ka hana ʻana i kahi keke kānana ma ka luawai. ʻO ka hoʻopiʻi maikaʻi ʻole e hana maikaʻi iā lākou i ka pale ʻana i ka shale hydration a me ka hoʻopuehu ʻana. Hiki i ka PAC ke hoʻomaikaʻi i ke kūpaʻa o ka luawai ma ka pale ʻana i ka neʻe ʻana o nā uku a me nā ʻāpana pālolo.

I ka hopena, polyanionic cellulose (PAC) he polymer versatile i hoʻohana ʻia i ka ʻoihana aila a me ke kinoea ma ke ʻano he mea hoʻohui wai wili. ʻO LV-PAC a me HV-PAC ʻelua mau māka maʻamau o PAC i hoʻohana ʻia no nā kumu like ʻole. Hoʻohana ʻia ʻo LV-PAC ma ke ʻano he mea hoʻoponopono kānana a ma ke ʻano he rheology modifier, ʻoiai ʻo HV-PAC e hoʻohana ʻia ma ke ʻano he viscosifier mua a me ka mea hoʻokele wai. ʻO nā papa ʻelua o ka PAC he polyanionic a maikaʻi i ka mālama ʻana i ka nalowale o ka wai a me ka pale ʻana i ka shale hydration a me ka hoʻopuehu.
