Hoʻopilikia ʻia ka cellulose ether e nā kumukūʻai pulupulu ulu
ʻO nā mea waiwai nui no ka cellulose ethers nā huahana mahiʻai a me nā ululāʻau, me ka pulupulu hoʻomaʻemaʻe, a me nā huahana kemika, me ka propylene oxide.ʻO ka mea maka o ka pulupulu i hoʻomaʻemaʻe ʻia ʻo ia ka pulupulu pōkole cashmere, a ʻo ka pulupulu pōkole cashmere i hana nui ʻia ma Shandong, Xinjiang, Hebei a me Jiangsu.ʻO ke kumu o ka hulu pulupulu he nui loa a lawa ka lako.
ʻO ka pulupulu ka hapa nui o ka hoʻokele waiwai o ka mahiʻai waiwai, a ua hoʻopili ʻia kona kumukūʻai e nā kūlana kūlohelohe a me nā lako a me nā koi honua.Pēlā nō, hoʻopilikia ʻia ka propylene oxide, chloromethane a me nā huahana kemika e nā kumukūʻai aila honua.Ma muli o ka helu ʻana o ka waiwai maka no ka hapa nui o ke kumukūʻai o ka cellulose ether, ʻo ka loli o ke kumu kūʻai waiwai e pili pono i ke kumukūʻai kūʻai o cellulose ether.
I mea e hoʻokō ai i ke koʻikoʻi o ke kumukūʻai, hoʻololi pinepine nā mea hana cellulose ether i ke kaomi i ka ʻoihana o lalo, akā pili ka hopena hoʻololi i ka paʻakikī o nā huahana ʻenehana, ʻokoʻa huahana a me ke kiʻekiʻe o ke kumukūʻai huahana a me ka waiwai hoʻohui.ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o nā ʻoihana me nā pale ʻenehana kiʻekiʻe, nā ʻāpana huahana waiwai a me ka waiwai hoʻohui kiʻekiʻe a e mālama i kahi pae waiwai nui.A i ʻole, pono nā ʻoihana e kū i ke koʻikoʻi o ke kumukūʻai.Eia kekahi, inā ʻaʻole paʻa ka kaiapuni o waho a he nui ka nui o ka fluctuations o ka huahana, ʻoi aku ka makemake o nā ʻoihana maka mua e koho i nā mea kūʻai aku i lalo me ka nui o ka hana a me ka ikaika holoʻokoʻa ikaika, i mea e hōʻoia ai i nā pono waiwai kūpono a hoʻemi i nā pilikia.No laila, kaupalena kēia i ka hoʻomohala ʻana o nā ʻoihana cellulose ether liʻiliʻi i kekahi ʻano.
ʻO ka cellulose ether kahi ʻano mea i loaʻa i ka polymer maoli, nona ka emulsification a me nā ʻano hoʻomaha.I nā ʻano like ʻole, ʻo ka hydroxypropyl methyl cellulose ether ʻo ia ka HPMC ka hua kiʻekiʻe loa, ʻo ia ka mea i hoʻohana nui ʻia, e piʻi wikiwiki ana kāna hana.
Me ka holomua o ka ʻepekema a me ka ʻenehana, ke ulu nei ka mākeke noi i lalo, a ke manaʻo ʻia nei ka hoʻonui ʻana o ka noi i lalo, a ke hoʻomau nei ka noi o lalo i ka ulu paʻa.Ma ka hale kūʻai o lalo o ka cellulose ether, nā mea kūkulu hale, ka ʻaila ʻaila, nā meaʻai a me nā māla ʻē aʻe e noho i kahi kūlana nui.I waena o lākou, ʻo ka ʻāpana mea kūkulu hale ka mākeke kūʻai nui loa, ʻoi aku ma mua o 30%.
ʻO ka ʻoihana kūkulu hale ka ʻoihana hoʻohana nui loa o nā huahana HPMC
I ka ʻoihana kūkulu, hoʻokani nā huahana HPMC i kahi paʻa koʻikoʻi, paʻa wai a me nā hopena ʻē aʻe.Ma hope o ka hoʻohui ʻana i kahi liʻiliʻi o ka HPMC me ka mortar sima, hiki ke hoʻonui ʻia ka viscosity, tensile a me ka ikaika shear o ka mortar sima, mortar a me ka binder, i mea e hoʻomaikaʻi ai i ka hana o nā mea kūkulu hale, e hoʻomaikaʻi i ka maikaʻi o ke kūkulu ʻana a me ka hana mechanical.Eia kekahi, he mea hoʻopaneʻe koʻikoʻi ka HPMC no ka hana ʻana a me ka lawe ʻana i ka pāpaʻi pāʻoihana, e hana ana i kahi kuleana i ka laka wai a me ka hoʻonui ʻana i nā waiwai rheological.I kēia manawa, ʻo HPMC ka huahana cellulose ether koʻikoʻi i hoʻohana ʻia i ke kūkulu ʻana i nā mea hoʻopaʻa.
ʻO ka ʻoihana kūkulu hale ka ʻoihana kia nui o ko kākou hoʻokele waiwai.Hōʻike ka ʻikepili i ka piʻi ʻana o ka hale kūkulu hale mai 7.08 biliona mau mika square i 2010 a i 14.42 biliona mau mika square ma 2019, e hoʻoikaika ikaika ana i ka ulu ʻana o ka mākeke cellulose ether.
Ua piʻi aʻe ka boom holoʻokoʻa o ka ʻoihana waiwai, a ua piʻi ka wahi o ke kūkulu ʻana a me ke kūʻai ʻana i kēlā me kēia makahiki.Hōʻike ka ʻikepili lehulehu i ka makahiki 2020, ke hoʻomau nei ka emi ʻana o kēlā me kēia makahiki i ka wahi kūkulu hou o nā hale noho hale kūʻai, ma lalo o 1.87% makahiki ma ka makahiki, 2021 e manaʻo ʻia e hoʻomau i ka hana hoʻoponopono.I nā mahina mua ʻelua o kēia makahiki, ua piʻi hou ka piʻi o ka ulu ʻana o nā hale noho hale kūʻai i 104.9%, he hoʻonui hanohano.

Hoʻopili nui ʻia ka mākeke ʻoihana ʻenehana drilling e nā hoʻopukapuka E&P o ka honua, me ka 40% o ka waihona ʻimi ʻimi honua i hoʻolaʻa ʻia i nā lawelawe ʻenehana drilling.
I ka wā o ka ʻaila ʻaila a me ka hana ʻana, he mea koʻikoʻi nā wai wili i ka lawe ʻana a me ka hoʻokuʻu ʻana i nā ʻāpana, ka hoʻoikaika ʻana i nā paia o ka lua a me ke kaupaona ʻana i ke kaomi hoʻokumu ʻana, ka hoʻoluʻu a me ka lubricating i ka bit, a me ka hoʻoili ʻana i nā mana hydrodynamic.No laila, i ka hana ʻaila ʻaila, he mea nui e mālama i ka haʻahaʻa kūpono, viscosity, fluidity a me nā hōʻailona ʻē aʻe o ka wai wili.Hiki i ka polyanionic cellulose, a i ʻole PAC, ke mānoanoa, lubricate i nā ʻāpana, a hoʻololi i nā mana hydrodynamic.Ma muli o nā kūlana geological paʻakikī o ka wahi mālama aila a me ka paʻakikī o ka ʻeli ʻana, aia ka nui o ka noi hoʻohana PAC.

Hoʻohana nui ʻia nā ethers cellulose non-ionic i ka ʻoihana lāʻau lapaʻau e like me nā mea hoʻohui lāʻau, e like me nā mānoanoa, dispersants, emulsifiers a me nā mea hana kiʻiʻoniʻoni.Hoʻohana ʻia ia no ka uhi kiʻiʻoniʻoni a me ka hoʻopili ʻana i nā papa lāʻau lapaʻau, a hiki ke hoʻohana ʻia i ka hoʻokuʻu ʻana, ka hoʻomākaukau ʻana i nā maka, nā papa lana a pēlā aku.Ma muli o nā koi koʻikoʻi e pili ana i ka maʻemaʻe a me ka viscosity o nā huahana cellulose ether lāʻau lapaʻau, paʻakikī ke kaʻina hana a ʻoi aku ka paʻakikī o nā kaʻina holoi.Ke hoʻohālikelike ʻia me nā huahana cellulose ether ʻē aʻe, ʻoi aku ka haʻahaʻa o ka hōʻiliʻili ʻana, ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana, akā ʻoi aku ka kiʻekiʻe o ka waiwai i hoʻohui ʻia.Hoʻohana nui ʻia nā excipients lāʻau lapaʻau i ka hoʻomākaukau lāʻau kemika, lāʻau lapaʻau patent Kina, nā huahana biochemical a me nā huahana lāʻau ʻē aʻe.
