1. Hoʻopuka pōkole o Cellulose Etera
ʻO ka cellulose ether kahi huaʻōlelo maʻamau no nā ʻano derivatives i loaʻa mai ka cellulose maoli (ka pulupulu i hoʻomaʻemaʻe ʻia a me ka pulp lāʻau, a me nā mea ʻē aʻe.) ʻO ka huahana hopena he derivative downstream o cellulose. Ma hope o ka etherification, hiki ke hoʻoheheʻe ʻia ka cellulose i ka wai, hoʻoheheʻe i ka hopena alkali a me ka mea hoʻoheheʻe organik, a loaʻa iā ia ka thermos plasticity. Nui nā ʻano cellulose ethers, i hoʻohana nui ʻia i ke kūkulu ʻana, sima, pena, lāʻau lapaʻau, meaʻai, petroleum, kemika i kēlā me kēia lā, textile, papermaking a me nā mea uila a me nā ʻoihana ʻē aʻe. E like me ka helu o nā substituents, hiki ke hoʻokaʻawale ʻia i hoʻokahi etera a hui pū ʻia, a e like me ka ionization, hiki ke hoʻokaʻawale ʻia i ka ionic cellulose ether a me ka non-ionic cellulose ether. I kēia manawa, loaʻa i nā huahana ionic cellulose ether ionic ka ʻenehana hana oʻo, hoʻomākaukau maʻalahi, haʻahaʻa haʻahaʻa ke kumu kūʻai, a haʻahaʻa haʻahaʻa haʻahaʻa. Hoʻohana nui ʻia lākou i nā mea hoʻohui meaʻai, nā mea kōkua textile, nā kemika i kēlā me kēia lā a me nā māla ʻē aʻe, a ʻo ia nā huahana nui i ka mākeke. huahana.
2. ʻO ka hoʻohana nui a me ka hana o ka cellulose ether
I kēia manawa, ʻo CMC, HPMC, MC, HEC, a me nā mea ʻē aʻe, ʻo CMC ka mea nui loa, ʻo ia ka hapalua o ka puka honua, ʻoiai ʻo HPMC a me MC e pili ana i ka 33% o ka honua. koi, a he helu HEC ma kahi o 30% o ka noi honua. 13% o ka mākeke. ʻO ka hoʻohana hope loa o ka carboxymethyl cellulose (CMC) he mea hoʻomaʻemaʻe, e helu ana ma kahi o 22% o ka noi ʻana o ka mākeke o lalo, a ʻo nā huahana ʻē aʻe e hoʻohana nui ʻia i nā kahua o nā mea kūkulu hale, nā meaʻai a me nā lāʻau lapaʻau.
Hoʻokaʻawale ʻia ka Global Cellulose Ether Demand ma ka huahana
3. Nā noi lalo
I ka wā ma mua, ma muli o ka liʻiliʻi o ka hoʻomohala ʻana o ka noi o koʻu ʻāina no ka cellulose ether i loko o ke kahua o nā kemika o kēlā me kēia lā, ka lāʻau lapaʻau, ka meaʻai, ka uhi ʻana, a me nā mea ʻē aʻe, ʻo ke koi no ka cellulose ether i koʻu ʻāina i hoʻopaʻa nui ʻia i ke kahua o nā mea kūkulu hale. A hiki i kēia lā, ʻoi aku ka nui o ka ʻoihana hana hale no 33% o ka noi cellulose ether o koʻu ʻāina. %. ʻO ke koi no ka cellulose ether o koʻu ʻāina ma ke kahua o nā mea kūkulu hale ua lilo i saturated, a ʻo ke koi ʻana i nā ʻoihana o kēlā me kēia lā, nā lāʻau lapaʻau, nā meaʻai, nā uhi, a me nā mea ʻē aʻe ke ulu wikiwiki nei me ka ulu ʻana o ka ʻenehana noi. No ka laʻana, i nā makahiki i hala iho nei, kanu nā capsules me ka cellulose ether ma ke ʻano he kumu maka, a me ka ʻiʻo artificial, kahi huahana e kū nei me ka cellulose ether, loaʻa nā manaʻo ākea ākea a me kahi lumi no ka ulu ʻana.
ʻO ka hapa o nā māhele mākeke o lalo o ka cellulose ether ma koʻu ʻāina
ʻO ka lawe ʻana i ke kahua o nā mea kūkulu hale ma ke ʻano he laʻana, he mau waiwai maikaʻi loa ka cellulose ether e like me ka mānoanoa, ka paʻa ʻana o ka wai, a me ka lohi. No laila, hoʻohana nui ʻia nā mea hana hale cellulose ether e hoʻomaikaʻi i ka hana ʻana o ka mīkini paʻa i hoʻomākaukau ʻia (me ka mortar wet-mixed and dry-mixed mortar), PVC resin, etc., latex paint, putty, etc., me ka hana o huahana mea hale. Mahalo i ka hoʻomaikaʻi ʻana o ka pae urbanization o koʻu ʻāina, ka wikiwiki o ka ulu ʻana o ka ʻoihana hale, ka hoʻomau mau ʻana o ke kiʻekiʻe o ka mīkini hana kūkulu, a me ka hoʻonui ʻana i nā koi o ka mālama ʻana i ka nohona o nā mea kūʻai aku no nā mea kūkulu hale ua hoʻoikaika i ka noi no ka non-ionic cellulose ethers. ma ke kahua o na mea kukulu hale. I loko o ka 13th Five-Year Plan, ua wikiwiki koʻu ʻāina i ka hoʻoponopono hou ʻana i nā hale kaona a me nā hale ʻinoʻino, a ua hoʻoikaika i ke kūkulu ʻana i nā ʻoihana kūlanakauhale, me ka wikiwiki o ka hoʻololi ʻana o nā shantytowns concentrated a me nā kauhale kūlanakauhale, me ka hoʻolaha ʻana i ka hoʻoponopono piha ʻana o nā hale noho kahiko, nā hale kahiko ʻinoʻino a me nā hoʻonohonoho piha ʻole. I ka hapa mua o 2021, ʻo 755.15 miliona mau mika square ka nui o nā hale noho hale hou, he piʻi o 5.5%. ʻO 364.81 miliona mau mika square ka hoʻopau ʻana o ka hale, kahi piʻi o 25.7%. ʻO ka hoʻihoʻi ʻana o ka wahi i hoʻopau ʻia o ka waiwai e hoʻokau i ka koi pili i ke kahua o nā mea kūkulu hale cellulose ether.
4. Ke kumu hoʻokūkū makeke
ʻO koʻu ʻāina kahi mea hana nui o ka cellulose ether ma ka honua. I kēia manawa, ua hoʻonohonoho pono ʻia ka hale hale hale cellulose ether. ʻO Shandong HEAD ka ʻoihana alakaʻi i ke kula o ka cellulose ether ma Kina. ʻO nā mea hana nui ʻē aʻe ʻo Shandong RUITAI, Shandong HEAD, North TIANPU Chemical, YICHENG Cellulose, a me nā mea ʻē aʻe. Coating-grade, pharmaceutical and food-grade cellulose ethers i kēia manawa i monopoli ʻia e nā hui haole e like me Dow, Ashland, Shin-Etsu, a me Lotte . Ma waho aʻe o Shandong HEAD a me nā hui'ē aʻe me ka nui o ka nui o 10,000 tons, he nui nā mea hana liʻiliʻi o ka non-ionic cellulose ethers me ka mana o 1,000 tons. ʻO nā meaʻai kiʻekiʻe a me nā huahana lāʻau lapaʻau.
5. Ka lawe ʻana a me ka lawe ʻana aku i ka cellulose ether
I ka makahiki 2020, ma muli o ka emi ʻana o ka mana hana o nā hui ʻē aʻe ma muli o ka maʻi maʻi ma waho, ua hōʻike ka nui o ka hoʻokuʻu ʻana o cellulose ether i koʻu ʻāina i ka ulu wikiwiki. I ka makahiki 2020, hiki i ka lawe ʻana aku i ka cellulose ether i 77,272 tons. ʻOiai ua ulu wikiwiki ka nui o ka hoʻokuʻu aku o ka cellulose ether o koʻu ʻāina, ke kūkulu nui nei nā huahana i waho i ka cellulose ether, ʻoiai he liʻiliʻi loa ka nui o ka lawe ʻana i ka lāʻau lapaʻau a me ka meaʻai cellulose ether, a he haʻahaʻa ka waiwai hoʻohui o nā huahana hoʻoiho. I kēia manawa, ʻehā ka nui o ka nui o ka cellulose ether o koʻu ʻāina i ka nui o ka lawe ʻana mai, akā ʻoi aku ka liʻiliʻi o ke kumu kūʻai aku ma mua o ka pālua o ka waiwai lawe mai. Ma ke kahua o nā huahana kiʻekiʻe, ʻo ke kaʻina hana hoʻololi i waho o ka cellulose ether home ka nui o ka lumi no ka hoʻomohala ʻana.
