ʻO ka sodium hiki ke hoʻoheheʻe ʻia i ka waicarboxymethyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose a me ka aila-soluble ethyl cellulose ua hoʻohana ʻia e like me nā Adhesives, disintegrants, hoʻomau a hoʻokuʻu ʻia nā mea hoʻokuʻu ʻia no ka hoʻomākaukau waha, ka uhi ʻana i nā mea hana kiʻiʻoniʻoni, nā mea capsule a me nā mea hoʻopaneʻe i hoʻohana ʻia i ka excipient agents. Ke nānā nei i ka honua, ua ʻike kekahi mau hui multinational haole (Shin-Etsu Japan, Dow Wolfe a me Ashland Cross Dragon) i ka mākeke nui o ka lāʻau cellulose e hiki mai ana ma Kina, ma ka hoʻonui ʻana i ka hana a i ʻole ka hui ʻana, a ua hoʻonui i kā lākou hana ma kēia kahua. hookomo noi iloko. Ua hoʻolaha ʻo Dow Wolfe e hoʻoikaika ʻo ia i ka hoʻokumu ʻana, nā mea hoʻohui a me nā koi o ka mākeke hoʻomākaukau lāʻau lapaʻau Kina, a ʻo kāna noiʻi noiʻi e hoʻoikaika pū e hoʻokokoke i ka mākeke. Ua hoʻokumu ʻo Dow Chemical Wolff Cellulose Division a me Colorcon Corporation o ʻAmelika Hui Pū ʻIa i kahi hui hoʻokuʻu hoʻokuʻu hoʻokuʻu ʻia ma ka pae honua, me ka ʻoi aku o 1,200 mau limahana ma 9 mau kūlanakauhale, 15 waiwai waiwai a me 6 mau hui GMP, kahi nui o nā loea noiʻi noiʻi lawelawe i nā mea kūʻai aku ma kahi o 160 mau ʻāina. Aia ʻo Ashland i nā kumu hana ma Beijing, Tianjin, Shanghai, Nanjing, Changzhou, Kunshan a me Jiangmen, a ua hoʻokomo i ʻekolu mau kikowaena noiʻi ʻenehana ma Shanghai a me Nanjing.
Wahi a nā helu helu mai ka pūnaewele o China Cellulose Association, i ka makahiki 2017, ʻo ka hana home o cellulose ether he 373,000 tons, a ʻo ka nui o ke kūʻai aku he 360,000 tons. Ma 2017, ʻo ka nui kūʻai maoli o ka ionic CMC he 234,000 tons, kahi hoʻonui o 18.61% makahiki-ma-makahiki, a me ka nui o ke kūʻai aku o ka non-ionic.CMChe 126,000 tons, he piʻi o 8.2% makahiki ma ka makahiki. Ma waho aʻe o ka HPMC (mea hana hale hale), nā huahana non-ionic, HPMC (ka lāʻau lapaʻau),HPMC(ka meaʻai),HEC, HPC, MC, HEMC, a me nā mea ʻē aʻe ua hoʻopiʻi i ke ʻano a ua hoʻomau ka hoʻonui ʻana i kā lākou hana a me nā kūʻai. Ua ulu wikiwiki ka home cellulose ether no nā makahiki he ʻumi, a ua lilo kāna huahana i mea mua ma ka honua. Eia naʻe, hoʻohana nui ʻia nā huahana o ka hapa nui o nā ʻoihana cellulose ether ma waena a me nā haʻahaʻa haʻahaʻa o ka ʻoihana, a ʻaʻole kiʻekiʻe ka waiwai hoʻohui.
I kēia manawa, ʻo ka hapa nui o nā ʻoihana cellulose ether home i ka wā koʻikoʻi o ka hoʻololi a me ka hoʻomaikaʻi ʻana. Pono lākou e hoʻonui i ka noiʻi a me ka hoʻomohala ʻana i nā huahana, hoʻomau i ka hoʻonui ʻana i nā ʻano huahana, hoʻohana piha iā Kina, ka mākeke nui loa o ka honua, a hoʻonui i ka hoʻoikaika ʻana e hoʻomohala i nā mākeke ʻē aʻe, i hiki i nā ʻoihana ke hoʻopau koke i ka hoʻololi ʻana a me ka hoʻomaikaʻi ʻana, komo i ke kahua waena a kiʻekiʻe o ka ʻoihana, a hoʻokō i ka ulu maikaʻi a me ka ʻōmaʻomaʻo.
