Polyanionic Cellulose High Viscosity (PAC HV)

ʻO ke kiʻekiʻe viscosity polyanionic cellulose (PAC-HV) kahi ʻano o ka cellulose derivative i hoʻohana nui ʻia ma ke ʻano he viscosifier a me ka hoʻoheheʻe ʻana i ka wai hoʻohui i nā ʻoihana like ʻole, ʻoi loa i ka wili a me ka hoʻopiha wai no ka ʻimi ʻaila a me ke kinoea. Eia kahi hiʻohiʻona o PAC-HV:

1. Hoʻohui: Loaʻa ka PAC-HV mai ka cellulose maoli ma o ka hoʻololi kemika e hoʻokomo i nā hui carboxymethyl a hoʻonui i kona solubility i ka wai. ʻO ke kiʻekiʻe o ka hoʻololi a me ke kaumaha molekala e hoʻoholo i ka viscosity a me nā hiʻohiʻona hana o PAC-HV.

2. Hana pono:

• Viscosifier: Hāʻawi ʻo PAC-HV i ka viscosity kiʻekiʻe i nā hoʻonā wai, e hana maikaʻi ia no ka hoʻomoʻa ʻana i nā wai wili a hoʻomaikaʻi i ko lākou hiki ke lawe no nā ʻoki ʻoki.
• Ka Mana Pohō Wai: Hoʻokumu ʻo PAC-HV i keke kānana lahilahi a impermeable ma ka paia luawai, e hōʻemi ana i ka lilo ʻana o ka wai i loko o ka hoʻokumu ʻana a mālama i ka paʻa o ka luawai.
• Hoʻololi Rheology: Hoʻololi ka PAC-HV i ka ʻano kahe a me nā waiwai rheological o nā wai wili, hoʻonui i ka hoʻokuʻu ʻana o nā mea paʻa a me ka hoʻohaʻahaʻa ʻana.

3. Nā noi:

• ʻO ka ʻaila ʻaila a me ke kinoea: Hoʻohana nui ʻia ka PAC-HV i nā wai hoʻoheheʻe wai no ka hana ʻana ma uka a me waho. Kōkua ia i ka mālama ʻana i ke kūpaʻa o ka wellbore, pale i ka pōʻino o ka hoʻokumu ʻana, a hoʻomaʻamaʻa i ka hana wili ʻana.
• Hana ʻia: Hoʻohana ʻia ʻo PAC-HV ma ke ʻano he mea mānoanoa a me ka mālama ʻana i ka wai i nā ʻano hana cementitious e like me nā grouts, slurries, a me nā morta i hoʻohana ʻia i nā noi kūkulu.
• ʻO nā lāʻau lapaʻau: Ma nā hana lāʻau lapaʻau, lawelawe ʻo PAC-HV ma ke ʻano he mea hoʻopaʻa, disintegrant, a me ka hoʻokuʻu hoʻokuʻu ʻia ʻana i ka papa papa a me ka capsule formulations.

4. Waiwai:

• Kiʻekiʻe Viscosity: Hōʻike ka PAC-HV i ka viscosity kiʻekiʻe i ka hopena, e hāʻawi ana i nā waiwai mānoanoa maikaʻi loa ma nā haʻahaʻa haʻahaʻa.
• Hiki ke hoʻoheheʻe wai: Hiki ke hoʻoheheʻe ʻia ka PAC-HV i ka wai, e ʻae ai i ka hoʻohui maʻalahi i loko o nā ʻōnaehana wai me ka ʻole o nā mea hoʻoheheʻe hou a i ʻole nā ​​mea hoʻopuehu.
• Thermal Stability: Mālama ʻo PAC-HV i kona viscosity a me nā hiʻohiʻona hana ma luna o kahi ākea o nā mahana i ʻike ʻia ma ka wili a me nā noi ʻoihana ʻē aʻe.
• ʻO ka hoʻomanawanui ʻana o ka paʻakai: Hōʻike ka PAC-HV i ka hoʻohālikelike maikaʻi me nā pae kiʻekiʻe o nā paʻakai a me nā brines e ʻike pinepine ʻia ma nā wahi ʻaila.

5. Ka maikaʻi a me nā kikoʻī:

• Loaʻa nā huahana PAC-HV i nā māka like ʻole a me nā kikoʻī i kūpono i nā noi kikoʻī a me nā koi hana.
• Hoʻopaʻa ʻia nā hana hoʻomalu maikaʻi i ka kūlike a me ka hoʻokō ʻana i nā kūlana ʻoihana, me nā kikoʻī API (American Petroleum Institute) no ka wili ʻana i nā mea hoʻohui wai.

I ka hōʻuluʻulu ʻana, ʻo ka PAC-HV kahi mea hoʻohui like ʻole me ka viscosity kiʻekiʻe, ka mālama ʻana i ka wai, a me nā waiwai rheological, e pono ai no nā noi ʻoihana like ʻole, ʻoi loa i ka hana ʻaila a me ke kinoea. ʻO kona hilinaʻi, hana, a me ka launa pū ʻana me nā mea hoʻohui ʻē aʻe e hāʻawi i kāna hoʻohana ākea i nā kaiapuni wili paʻakikī.
