ʻO ka cellulose ether kahi ʻano mea i loaʻa i ka polymer maoli, nona nā ʻano o ka emulsification a me ka hoʻokuʻu.Ma waena o nā ʻano he nui, ʻo HPMC ka mea me ka mea kiʻekiʻe loa a me ka hoʻohana nui ʻia, a ke piʻi wikiwiki nei kāna huahana.
I nā makahiki i hala iho nei, mahalo i ka ulu ʻana o ka hoʻokele waiwai o ka ʻāina, ua hoʻonui ʻia ka hana o ka cellulose ether i koʻu ʻāina i kēlā me kēia makahiki.I ka manawa like, me ka hoʻomohala ʻana o ka ʻepekema kūloko a me ka ʻenehana, nā cellulose ethers kiʻekiʻe i koi mua ʻia i ka nui o ka lawe ʻana mai i kēia manawa, a ke hoʻomau nei ka piʻi ʻana o ka nui o nā cellulose ethers home.Hōʻike ka ʻikepili mai Ianuali a Nowemapa 2020, ua hōʻea ka cellulose ether o Kina i 64,806 tons, kahi hoʻonui makahiki o 14.2%, ʻoi aku ka kiʻekiʻe ma mua o ka nui o ka lawe ʻana no ka makahiki 2019.
Hoʻopili ʻia ka cellulose ether e nā kumukūʻai pulupulu ulu：
ʻO nā mea waiwai nui o ka cellulose ether e pili ana i 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 hoʻomaʻemaʻe ʻia he pulupulu linters.ʻO koʻu ʻāina ka nui o ka hana pulupulu, a ʻo nā wahi hana o nā linters pulupulu ka mea nui ma Shandong, Xinjiang, Hebei, Jiangsu a me nā wahi ʻē aʻe.He nui loa ka pulupulu a me ka lako.
Noho ka pulupulu i ka hapa nui o ka hoʻokele waiwai mahiʻai, a ua hoʻopilikia ʻia kona kumukūʻai e nā ʻano he nui e like me nā kūlana kūlohelohe a me nā lako a me nā koi honua.Pēlā nō, hoʻopilikia ʻia nā huahana kemika e like me propylene oxide a me methyl chloride e nā kumukūʻai aila ʻaila honua.Ma muli o ka helu ʻana o nā kumu waiwai no ka hapa nui o ke kumu kūʻai o cellulose ether, ʻo ka fluctuations o nā kumukūʻai kumu waiwai e pili pono i ke kumukūʻai kūʻai o cellulose ether.
I ka pane ʻana i ke koʻikoʻi o ke kumukūʻai, hoʻololi pinepine nā mea hana cellulose ether i ke kaomi i nā ʻoihana o lalo, akā pili ka hopena o ka hoʻololi ʻana e ka paʻakikī o nā huahana ʻenehana, nā ʻokoʻa huahana a me nā kumu kūʻai i hoʻohui ʻia.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 nā ʻoihana i kahi pae paʻa o ka loaʻa kālā;a i ʻole, pono nā ʻoihana e kū i ke koʻikoʻi o ke kumukūʻai.Eia kekahi, inā ʻaʻole paʻa ke kaiapuni o waho a he nui ka nui o ka fluctuations o nā huahana, ʻoi aku ka makemake o nā ʻoihana o ka upstream raw material e koho i nā mea kūʻai aku i lalo me ka nui o ka hana a me ka ikaika piha ikaika e hōʻoia i ka pono o ka hoʻokele waiwai a hōʻemi i nā pilikia.No laila, kaupalena kēia i ka hoʻomohala ʻana o nā ʻoihana cellulose ether liʻiliʻi i kekahi ʻano.
Hoʻolālā Makeke i lalo：
Me ka holomua mau o ka ʻepekema a me ka ʻenehana, e ulu ka mākeke koi i lalo.I ka manawa like, manaʻo ʻia ka hoʻonui ʻia ʻana o nā noi i lalo, a e hoʻomau ka noi ʻana i lalo i ka ulu mau.Ma ka hale kūʻai o lalo o ka cellulose ether, nā mea kūkulu hale, ka ʻimi 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 mea kūʻai nui loa o nā huahana HPMC：
Ma ka ʻoihana kūkulu hale, he kuleana koʻikoʻi nā huahana HPMC i ka hoʻopaʻa ʻana a me ka mālama ʻana i ka wai.Ma hope o ka hui ʻana i kahi liʻiliʻi o ka HPMC me ka mortar sima, hiki iā ia ke hoʻonui i ka viscosity, tensile a me ka ikaika shear o ka mortar sima, mortar, binder, etc., no laila e hoʻomaikaʻi ai i ka hana o nā mea kūkulu hale, hoʻomaikaʻi i ka maikaʻi o ke kūkulu ʻana a me ka pono hana mechanical.Eia kekahi, he mea hoʻopaneʻe koʻikoʻi ka HPMC no ka hana ʻana a me ka lawe ʻana i ka pāpaʻi pāʻoihana, hiki ke hoʻopaʻa i ka wai a hoʻonui i ka rheology o ke koki.I kēia manawa, ʻo HPMC ka huahana cellulose ether nui i hoʻohana ʻia i ke kūkulu ʻana i nā mea hoʻopaʻa.
ʻO ka ʻoihana kūkulu hale he ʻoihana kia nui o koʻu ʻāina.Hōʻike ka ʻikepili i ka piʻi ʻana o ke kūkulu hale kūkulu hale mai 7.08 biliona mau mika square i 2010 a i 14.42 biliona mau mika square ma 2019, ka mea i hoʻoikaika ikaika i ka ulu ʻana o ka mākeke cellulose ether.
Ua piʻi hou ka pōmaikaʻi holoʻokoʻa o ka ʻoihana waiwai, a ua hoʻonui ʻia ke kūkulu hale a me nā wahi kūʻai aku i kēlā me kēia makahiki.Hōʻike ka ʻikepili lehulehu i ka makahiki 2020, ʻo ka emi ʻana o kēlā me kēia makahiki i ka makahiki i ke kūkulu hou ʻana o nā hale noho hale kūʻai ua hōʻemi ʻia, a ʻo ka emi ʻana o ka makahiki ma ka makahiki he 1.87%.I ka makahiki 2021, manaʻo ʻia e hoʻomau ka hoʻihoʻi hou ʻana.Mai Ianuali a Pepeluali i kēia makahiki, ua piʻi hou ka ulu ʻana o ka wahi kūʻai o nā hale kūʻai hale a me nā hale noho i 104,9%, he piʻi nui.
Ka ʻaila ʻaila:
Hoʻopili nui ʻia ka mākeke ʻoihana ʻenehana drilling e ka ʻimi honua a me ka hoʻomohala hoʻomohala ʻana, me ka 40% o ka waihona ʻimi honua i hoʻolaʻa ʻia i nā lawelawe ʻenehana drilling.
I ka wā o ka ʻaila ʻaila, he hana koʻikoʻi ka wai wili i ka lawe ʻana a me ka hoʻokuʻu ʻana i nā ʻokiʻoki, ka hoʻoikaika ʻana i nā paia puka a me ke kaupaona ʻana i ke kaomi ʻana, ka hoʻoluʻu a me ka lubricating drill bits, a me ka hoʻouna ʻana i ka ikaika hydrodynamic.No laila, i ka hana ʻaila ʻaila, he mea nui ka mālama ʻana i ka haʻahaʻa kūpono, viscosity, fluidity a me nā mea hōʻailona ʻē aʻe o ka wai drilling.Hiki i ka polyanionic cellulose, PAC, ke mānoanoa, lubricate i ka drill bit, a hoʻoili i ka ikaika hydrodynamic.Ma muli o nā kūlana geological paʻakikī i ka wahi e mālama ai i ka aila a me ka paʻakikī o ka wili ʻana, aia kahi koi nui no PAC.
ʻoihana lako lāʻau lapaʻau:
Nonionic cellulose ethers ua hoʻohana nui ʻia i ka ʻoihana lāʻau lapaʻau e like me nā mea hoʻohui lāʻau e like me nā thickeners, 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 no ka hoʻokuʻu ʻana, ka hoʻomākaukau ophthalmic, nā papa lana, a me nā mea ʻē aʻe. paʻakikī a ʻoi aku ka nui o nā kaʻina holoi holoi.Ke hoʻohālikelike ʻia me nā helu ʻē aʻe o nā huahana cellulose ether, ʻoi aku ka haʻahaʻa o ka hōʻiliʻili ʻana a ʻoi aku ka kiʻekiʻe o ke kumukūʻai hana, akā ʻoi aku ka kiʻekiʻe o ka waiwai hoʻohui o ka huahana.Hoʻohana nui ʻia nā excipients lāʻau lapaʻau i nā huahana hoʻomākaukau e like me ka hoʻomākaukau kemika, nā lāʻau patent Kina a me nā huahana biochemical.
Ma muli o ka hoʻomaka ʻana o ka ʻoihana mea hoʻolaʻa lāʻau lapaʻau o koʻu ʻāina, haʻahaʻa ka pae hoʻomohala holoʻokoʻa o kēia manawa, a pono e hoʻomaikaʻi hou ʻia ka ʻenehana ʻoihana.I loko o ka waiwai hoʻopuka o nā hoʻomākaukau lāʻau lapaʻau home, ʻo ka waiwai hoʻopuka o nā lole lāʻau lapaʻau kūloko e pili ana i kahi haʻahaʻa haʻahaʻa o 2% a 3%, ʻoi aku ka haʻahaʻa ma mua o ka hapa o nā mea hoʻohana lāʻau lapaʻau haole, ʻo ia ka 15%.Hiki ke ʻike ʻia he nui ka lumi no ka hoʻomohala ʻana i nā excipients pharmaceutical home., Manaʻo ia e hoʻoulu maikaʻi i ka ulu ʻana o ka mākeke cellulose ether pili.
Mai ka hiʻohiʻona o ka home cellulose ether production, ʻo Shandong Head ka mea hana nui loa, ʻo ia ka 12.5% o ka nui o ka mana hana, a ukali ʻia e Shandong RUITAI, Shandong YITENG, North TIANPU Chemical a me nā ʻoihana ʻē aʻe.Ma ke ʻano holoʻokoʻa, paʻakikī ka hoʻokūkū ma ka ʻoihana, a ke manaʻo ʻia nei e piʻi hou ka manaʻo.
