ʻO ka Hydroxyethyl Cellulose (HEC) he polymer hiki ke hoʻohana nui ʻia i ka ʻaila ʻaila. ʻO kāna mau waiwai kino a me kemika e hāʻawi iā ia i nā pono he nui i kēia kahua.
1. Hoʻomaikaʻi i nā waiwai rheological
He mau waiwai mānoanoa ka Hydroxyethyl cellulose a hiki ke hoʻonui nui i ka viscosity o ka wai wili. He mea koʻikoʻi kēia waiwai i ka wā o ka wili ʻana, no ka mea hiki i nā wai hoʻoheheʻe kiʻekiʻe ke hoʻopaneʻe maikaʻi i nā ʻoki drill a pale iā lākou mai ka waiho ʻana ma lalo o ka luawai a i ʻole ma ka pā paipu, a laila e hoʻomaikaʻi ai i ka maikaʻi a me ka palekana. ʻO ke ʻano pseudoplastic o nā haʻina HEC ka hopena i ka haʻahaʻa haʻahaʻa i ka nui o ka shear rate (e like me kahi kokoke i ka drill bit), ka mea e hōʻemi ai i ka friction a me ka pumping power, a me ka viscosity kiʻekiʻe ma nā haʻahaʻa shear rates (e like me kahi kokoke i ka pā punawai), e kōkua ana no ka lawe ʻana. a me ka hoʻopaneʻe ʻana i nā ʻoki wili.
2. ʻO ka hydration a me ka mālama wai
Loaʻa i ka Hydroxyethyl cellulose nā waiwai hydration maikaʻi loa a hiki ke hoʻoheheʻe koke i ka wai a hana i kahi hopena kūlike. Hoʻomaʻamaʻa kēia hana i ka hoʻomākaukau wikiwiki a me ka hoʻoponopono ʻana i nā hoʻoheheʻe wai ʻana ma ka pūnaewele, e hoʻonui ana i ka maʻalahi o ka hana. Eia kekahi, loaʻa iā HEC nā waiwai paʻa wai ikaika, hiki ke hōʻemi i ka evaporation a me ka nalowale o ka wai i nā wai wili a mālama i ka paʻa a me ka maikaʻi o nā wai wili. ʻOi aku ka nui o ka wela a me ke kaomi kiʻekiʻe, ʻoi aku ka nui o kāna mau waiwai paʻa wai.
3. Kānana kānana
I ka wā o ka wili ʻana, ʻo ka lilo ʻana o ka wai o ka wai wili he mea koʻikoʻi. ʻO ka nui o ka hoʻoheheʻe ʻana e alakaʻi i ka hoʻonui ʻana i ka mānoanoa o ke keke lepo, kahi e alakaʻi ai i nā pilikia e like me ka paʻa ʻole o ka paia a me ka leakage. Hiki i ka Hydroxyethyl cellulose ke hoʻemi pono i ka nalowale o ka wai o ka wai wili, hana i kahi keke kānana paʻa, hoʻemi i ka hopena o ka leakage a hāʻule o ka pā luawai, a hoʻomaikaʻi i ka paʻa o ka pā punawai. Eia kekahi, hiki i ka HEC ke mālama i ka hana paʻa ma lalo o nā ʻano pH like ʻole a me nā kūlana hoʻokele electrolyte a hoʻololi i nā kūlana geological paʻakikī.
4. Pili kaiaola
Ke piʻi nei ka paʻakikī o ka hoʻoponopono ʻana i ke kaiapuni, ke piʻi nui nei ka koi no nā wai drilling friendly. Ma ke ʻano he cellulose derivative, hydroxyethyl cellulose he biodegradability maikaʻi a he liʻiliʻi ka hopena i ke kaiapuni. Hoʻohālikelike ʻia me kekahi mau polymers synthetic, ʻo ka hoʻohana ʻana i ka HEC e hōʻemi i nā hoʻokuʻu ʻino a kōkua i ka hoʻokō ʻana i nā pahuhopu wili ʻōmaʻomaʻo. Eia kekahi, ʻo ke ʻano non-toxic a me ka ʻino ʻole o HEC e hōʻemi ana i nā pilikia i ke olakino o ka mea hoʻohana.
5. Hoʻokele waiwai
ʻOiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ka hydroxyethyl cellulose, ʻo kāna hana maikaʻi loa i ka wā hoʻohana hiki ke hōʻemi nui i ke kumukūʻai holoʻokoʻa i ke kaʻina hana wili. ʻO ka mea mua, ʻo ka mānoanoa a me ka mālama wai ʻana o HEC e hōʻemi i ka nui o ka wai wili a me nā kumu waiwai. ʻO ka lua, ʻo ke kūpaʻa a me ka hilinaʻi o HEC e hōʻemi i ka hopena o ka hāʻule ʻana o lalo o ka honua a me nā pani ʻole i hoʻolālā ʻia, e hōʻemi ana i nā kumukūʻai mālama a hoʻoponopono. ʻO ka mea hope loa, hoʻemi ka waiwai o ka HEC i ka hoʻolilo ʻana i ka ʻōpala a me ka mālama kaiapuni.
6. Hoʻohālikelike a me Versatility
Hiki i ka Hydroxyethyl cellulose ke kūpaʻa kemika maikaʻi a me ka laulā ākea, a hiki ke kūpono me nā ʻano mea hoʻohui like ʻole a me nā ʻōnaehana wai wili e hana i kahi ʻōnaehana composite me nā hana kikoʻī. No ka laʻana, hiki ke hoʻohana pū ʻia ʻo HEC me nā anti-collapse agents, anti-leak agents a me lubricants e hoʻomaikaʻi i ka hana piha o nā wai wili a hoʻokō i nā kūlana geological like ʻole a me nā pono wili. Eia kekahi, hiki ke hoʻohana ʻia ʻo HEC i nā kemika ʻaila ʻē aʻe e like me ka wai hoʻopiha a me nā wai fracturing, e hōʻike ana i kona versatility.
He waiwai nui ka Hydroxyethyl cellulose i ka hoʻoheheʻe ʻana i ka aila, ʻike nui ʻia i ka hoʻomaikaʻi ʻana i nā waiwai rheological, ka hoʻonui ʻana i ka hydration a me ka paʻa wai paʻa, ka hoʻomalu pono ʻana i ka nui o ka kānana, ʻo ia ka launa ʻana, ka waiwai a me ka multifunctional. ʻO kēia mau mea maikaʻi e hoʻolilo iā HEC i mea koʻikoʻi a koʻikoʻi hoʻi i ke kaʻina hana wili ʻaila, e kōkua ana i ka hoʻokō ʻana i nā hana wili maikaʻi, palekana a me ke kaiapuni. Me ka hoʻomau mau ʻana o ka ʻenehana a me ka hohonu o ka noi, e ʻoi aku ka laulā o ka noi ʻana o ka hydroxyethyl cellulose i ka ʻaila ʻaila.
