ʻO kahi hoʻolauna pōkole o cellulose ether

ʻO ka cellulose ether he cellulose maoli (ka pulupulu hoʻomaʻemaʻe a me ka pulp lāʻau, a me nā mea ʻē aʻe) ma ke ʻano he kumu waiwai, ma hope o ka etherification o nā ʻano derivatives, ʻo ia ka cellulose macromolecule hydroxyl hydrogen e ka hui ether i hoʻololi ʻia ma hope o ka hoʻokumu ʻia ʻana o nā huahana, ʻo ia ka derivatives downstream. o ka cellulose.Hiki ke hoʻoheheʻe ʻia ka cellulose i ka wai, hoʻoheheʻe i ka hopena alkali a me ka mea hoʻoheheʻe organik ma hope o ka etherification, a loaʻa iā ia nā waiwai thermoplastic.ʻO keʻano o ka cellulose ether, hoʻohana nuiʻia i ke kūkuluʻana, ka sima, ka uhiʻana, ka lāʻau lapaʻau, ka meaʻai, kaʻaila, ka lāʻau kemika, textile, pepa a me nā mea uila a me nāʻoihana'ē aʻe.E like me ka helu o ka substituents hiki ke maheleia i hookahi etera a huikau etera, e like me ka ionization hiki ke maheleia i ionic cellulose etera a me ka non-ionic cellulose etera.I kēia manawa, ʻo ka ionic cellulose ether ionic product production kaʻina hana, maʻalahi ke hana a me ke kumu kūʻai haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa, hoʻohana nui ʻia i nā mea hoʻohui meaʻai, textile additives, lāʻau kemika a me nā māla ʻē aʻe, ʻo ia ka huahana hana nui ma ka mākeke.

I kēia manawa, ʻo CMC, HPMC, MC, HEC a me nā mea ʻē aʻe, ʻo CMC ka mea nui loa, e helu ana no ka hapalua o ka puka honua, ʻoiai ʻo HPMC a me MC e pili ana i ka 33% o ka noi honua. Aia ʻo HEC ma kahi o 13% o ka mākeke honua.ʻO ka hoʻohana hope loa o ka carboxymethyl cellulose (CMC) he mea hoʻomaʻemaʻe, e helu ana ma kahi o 22% o ka noi o ka mākeke o lalo, a ʻo nā huahana ʻē aʻe e hoʻohana nui ʻia i nā mea kūkulu hale, nā meaʻai a me nā lāʻau lapaʻau.

Ii.Hoʻohana i lalo

I ka wā ma mua, ma muli o ka palena o ka hoʻomohala ʻana o ka cellulose ether i kēlā me kēia lā, nā lāʻau lapaʻau, nā meaʻai, nā uhi a me nā ʻāina ʻē aʻe ma Kina, ʻo ke koi ʻana no ka cellulose ether ma Kina e hoʻopaʻa nui ʻia i ke kahua o nā mea kūkulu hale, a hiki i kēia lā, ka hale. Noho mau ka ʻoihana waiwai i ka 33% o ka noi no cellulose ether ma Kina.A e like me ka cellulose ether o Kina i ke kula o nā mea kūkulu hale ua lilo i saturated, i nā kemika i kēlā me kēia lā, lāʻau lapaʻau, meaʻai, uhi a me nā ʻano ʻē aʻe o ka noi e ulu wikiwiki nei me ka hoʻomohala ʻana o ka ʻenehana noi.No ka laʻana, i nā makahiki i hala iho nei, ʻo ka mea kanu capsule me ka cellulose ether ka mea kumu nui, a me nā huahana e puka mai ana i hana ʻia i ka ʻiʻo artificial me ka cellulose ether he ākea ka makemake a me ka ulu ulu.

Ma ke kahua o nā mea kūkulu hale, no ka laʻana, cellulose ether me ka mānoanoa, ka paʻa ʻana o ka wai, ka condensation lohi a me nā ʻano maikaʻi ʻē aʻe, no laila ua hoʻohana nui ʻia nā mea kūkulu hale cellulose ether e hoʻomaikaʻi ai i ka hana o nā huahana hale me ka mortar mākaukau (me ka pulu. i hui ʻia a me ka maloʻo maloʻo maloʻo), PVC resin manufacturing, latex paint, putty, etc. a ke piʻi aʻe nei nā koi kaiapuni o nā mea kūʻai aku no nā mea kūkulu hale, e alakaʻi ana i ka koi no ka non-ionic cellulose ether ma ke kahua o nā mea kūkulu hale.I ka manawa o ka 13th Five-Year Plan, ua hoʻolalelale ʻo Kina i ka hoʻoponopono hou ʻana i nā wahi ʻōpala a me nā hale ʻino i loko o nā kūlanakauhale, a hoʻoikaika i ke kūkulu ʻana i nā ʻoihana kūlanakauhale, me ka wikiwiki o ka hoʻoponopono ʻana i nā wahi a me nā kauhale o nā kūlanakauhale, a me ka hoʻolaha ʻana i ka hoʻoponopono piha nā wahi noho kahiko a me ka hoʻoponopono hou ʻana i nā hale ʻeleʻele a me nā hale noho piha ʻole.I ka hapa mua o 2021, ua hoʻomaka ʻia ka 755.15 miliona square square o nā wahi noho, ʻoi aku ka 5.5 pakeneka.ʻO 364.81 miliona mau mika square ka hoʻopau ʻia o ka hale, ʻoi aku ka 25.7%.ʻO ka hoʻihoʻi hou ʻana o ka wahi i hoʻopau ʻia o ka waiwai paʻa e alakaʻi i ka koi kūpono i ke kahua o nā mea kūkulu hale cellulose ether.

3. Ke kumu hoʻokūkū makeke

China mea he global cellulose etera hana 'āina, i keia manawa o ka hale hale hale papa cellulose etera ua basically loaa localization, Anxin Chemistry alakai 'oihana i loko o ke kula o cellulose etera, 'ē aʻe nui hale hana pū kekahi me Kima Chemical etc. Coating pae, pharmaceutical. ʻO ka meaʻai cellulose ether ka nui o ka United States Dow, Ashland, Japan shinetsu, South Korea Lotte a me nā monopoly haole.A ʻo kekahiKemika Anxinʻoi aku ma mua o ʻumi kaukani mau ʻoihana, nā kaukani o ka non-ionic cellulose ether nā ʻoihana liʻiliʻi liʻiliʻi, ʻo ka hapa nui o kēia mau ʻoihana liʻiliʻi e hana i nā mea hana hale kumu hoʻohālike maʻamau cellulose ether, a ʻaʻohe ikaika e hana i nā meaʻai kiʻekiʻe a me nā huahana lāʻau.

ʻEhā, ke kūlana hoʻokomo a me ka hoʻoiho cellulose ether

I ka makahiki 2020, ma muli o ka maʻi maʻi ʻē aʻe i alakaʻi ai i ka emi ʻana o ka mana hana o nā ʻoihana ʻē aʻe, ua hōʻike ʻo Kina cellulose ether exports i ka ulu wikiwiki ʻana, i ka makahiki 2020 e hoʻokō i ka lawe ʻana i ka cellulose ether 77,272 tons.ʻOiai ke ulu wikiwiki nei ka nui o ka cellulose ether ma Kina, ua hoʻokumu nui ʻia nā huahana e hoʻokuʻu aku i nā mea kūkulu hale cellulose ether, ʻoiai ka liʻiliʻi o ka nui o ka lāʻau lapaʻau a me ka cellulose ether e ʻai ʻia, a he haʻahaʻa ka waiwai hoʻohui o nā huahana export.I kēia manawa, ʻehā ka nui o ka nui o ka cellulose ether ma Kina i ka nui o ka lawe ʻana mai, akā ʻoi aku ka liʻiliʻi o ka nui o ka lawe ʻana ma mua o ʻelua mau manawa i ka nui o ka lawe ʻana mai.Ma ke kahua o nā huahana kiʻekiʻe o ka home cellulose ether export substitution kaʻina he wahi nui no ka hoʻomohala ʻana.
