He aha ka mea e ulu ai ka mākeke o ka ʻoihana cellulose ether o Kina i 2022?

Wahi a ka "China Cellulose Ether Industry Research and Investment Forecast Report (2022 Edition)" i hoʻokuʻu ʻia e Li mu Information Consulting, ʻo ka cellulose ka mea nui o nā paia o nā mea kanu a me ka polysaccharide i hoʻolaha nui ʻia a nui loa.ʻOi aku ia ma mua o 50% o ke kalapona o ke aupuni mea kanu.Ma waena o lākou, kokoke i ka 100% ka helu cellulose o ka pulupulu, ʻo ia ke kumu cellulose kūlohelohe maoli.I ka lāʻau maʻamau, helu ʻia ka cellulose no 40-50%, a aia he 10-30% hemicellulose a me 20-30% lignin.

ʻO ka ʻoihana cellulose ether ʻē aʻe he ʻano oʻo, a ua monopoli ʻia e nā ʻoihana nui e like me Dow Chemical, Ashland, a me Shin-Etsu.He 360,000 tons ka nui o ka cellulose ether production o nā hui ʻē aʻe, a ʻo Shin-Etsu o Iapana a me Dow o ʻAmelika Hui Pū ʻIa he 100,000 tons, Ashland 80,000 tons, a me Lotte ma luna o 40,000 tons (kūʻai iā Samsung. ʻO nā ʻoihana e pili ana), ʻo nā mea hana ʻehā kiʻekiʻe ʻO ka hiki ke hoʻonui ʻia ma mua o 90% (koe ka mana hana o Kina).Hāʻawi ʻia kahi helu liʻiliʻi o ka lāʻau lapaʻau, nā huahana meaʻai a me nā cellulose ethers hale kiʻekiʻe e pono ai ma koʻu ʻāina e nā hui haole kaulana.

I kēia manawa, ʻo ka hapa nui o ka mana hana o nā mea hale maʻamau-grade cellulose ethers i hoʻonui ʻia ma Kina ua hoʻoikaika i ka hoʻokūkū o nā huahana haʻahaʻa haʻahaʻa haʻahaʻa, ʻoiai nā lāʻau lapaʻau a me nā huahana meaʻai me nā pale ʻenehana kiʻekiʻe ka papa pōkole. ʻoihana cellulose ether o koʻu ʻāina.

Ua hoʻomaikaʻi maikaʻi ʻia ka maikaʻi a me ka hana o ka carboxymethyl cellulose a me kāna mau huahana paʻakai ma koʻu ʻāina i nā makahiki i hala iho nei, a ua hoʻonui ʻia ka nui o ka lawe ʻana i kēlā me kēia makahiki.Ua hilinaʻi nui ʻia ka makemake o ka mākeke ma nā ʻāina ʻē, a ua piha ka mākeke.ʻO ka lumi no ka uluʻana o ka wā e hiki mai ana he palena iki.

Nonionic cellulose ethers, me ka hydroxyethyl, propyl, methylcellulose a me kā lākou derivatives, loaʻa nā manaʻo kūʻai maikaʻi i ka wā e hiki mai ana, ʻoi aku hoʻi i nā noi kiʻekiʻe, aia nō kahi wahi hoʻomohala mākeke nui.E like me ka lāʻau lapaʻau, ka pena kiʻekiʻe, nā seramika kiʻekiʻe, a me nā mea ʻē aʻe e pono e lawe ʻia mai.Aia nō ka nui o ka lumi no ka hoʻomaikaʻi ʻana i ke kiʻekiʻe o ka ʻenehana hana a me ka noiʻi a me ka hoʻomohala ʻana, a aia kekahi mau manawa hoʻolimalima nui.

I kēia manawa, haʻahaʻa ke kiʻekiʻe o nā lako mīkini no ka hoʻomaʻemaʻe ʻana i ka home, ka mea e kaohi nui i ka hoʻomohala ʻana i ka ʻoihana.ʻO ka haumia nui o ka huahana he sodium chloride.I ka wā ma mua, ua hoʻohana nui ʻia nā centrifuges ʻekolu wāwae i koʻu ʻāina, a ʻo ke kaʻina hana hoʻomaʻemaʻe he hana intermittent, ʻo ia ka hana-koʻikoʻi, ka ikehu a me ka waiwai.He paʻakikī hoʻi ka maikaʻi o ka huahana.ʻO ka hapa nui o nā laina hana hou i lawe mai i nā mea hana ʻē aʻe e hoʻomaikaʻi ai i ka pae o ka lako, akā aia nō kahi āpau ma waena o ka automation o ka laina hana holoʻokoʻa a me nā ʻāina ʻē.Hiki i ka hoʻomohala ʻana o ka ʻoihana ke noʻonoʻo i ka hui pū ʻana o nā lako ʻē aʻe a me nā lako hale, a me nā lako lawe mai i nā loulou kī e hoʻomaikaʻi i ka automation o ka laina hana.Ke hoʻohālikelike ʻia me nā huahana ionic, ʻoi aku ka kiʻekiʻe o nā ethers cellulose non-ionic, a he mea koʻikoʻi ia e uhaki i nā pale ʻenehana i ka ʻenehana hana a me ka hoʻonui noi.
