Cellulose Etera (HPMC,MC,HEC,EC,HPC,CMC,PAC)

ʻO nā cellulose ethers kahi hui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose, kahi polymer kūlohelohe i loaʻa i loko o nā paia o nā mea kanu. Hoʻohana nui ʻia lākou i nā ʻoihana like ʻole no kā lākou mānoanoa, hoʻokūpaʻa, hana kiʻiʻoniʻoni, a me nā waiwai mālama wai. Eia kahi ʻike pōkole o kekahi mau ʻano maʻamau o ka cellulose ethers:

1. ʻO Hydroxypropyl Methylcellulose (HPMC): ʻO ka HPMC he cellulose ether maʻamau i hoʻohana nui ʻia i ke kūkulu ʻana, nā lāʻau lapaʻau, mālama pilikino, a me nā ʻoihana meaʻai. Ua ʻike ʻia no kona paʻa ʻana i ka wai maikaʻi, mānoanoa, a me nā waiwai hana kiʻiʻoniʻoni. Hoʻohana mau ʻia ka HPMC ma ke ʻano he mānoanoa, binder, a me rheology modifier i loko o ka mortar, tile adhesives, pharmaceutical tablets, cosmetics, a me nā huahana meaʻai.
2. Methylcellulose (MC): Ua like ka MC me HPMC akā he haʻahaʻa haʻahaʻa o ka hoʻololi ʻana me nā hui methyl. Hoʻohana ʻia ia i nā noi kahi e koi ʻia ai ka paʻa ʻana o ka wai haʻahaʻa a me ka viscosity, e like me ka hoʻomākaukau ʻana i ka lāʻau lapaʻau, nā hopena ophthalmic, a ma ke ʻano he mānoanoa i nā huahana meaʻai.
3. ʻO Hydroxyethyl Cellulose (HEC): ʻO HEC kekahi mea i hoʻohana nui ʻia i ka cellulose ether i ʻike ʻia no kona paʻa wai maikaʻi a me nā waiwai mānoanoa. Hoʻohana maʻamau ia i nā mea hana e like me nā pena, nā uhi, a me nā mea hoʻopili, a me nā huahana mālama pilikino e like me nā shampoos, lotions, a me nā ʻaila.
4. Ethyl Cellulose (EC): EC he cellulose ether i hoʻololi ʻia me nā hui ethyl. Hoʻohana nui ʻia ia i nā lāʻau lapaʻau, nā uhi, a me nā noi kūikawā kahi e pono ai kāna hana kiʻiʻoniʻoni, pale, a me nā waiwai hoʻokuʻu hoʻomau. Hoʻohana pinepine ʻia ʻo EC ma ke ʻano he mea uhi no nā papa a me nā pellets i nā ʻano lāʻau lapaʻau.
5. Hydroxypropyl Cellulose (HPC): He cellulose ether ka HPC i hoʻololi ʻia me nā hui hydroxypropyl. Hoʻohana maʻamau ia ma ke ʻano he mānoanoa, binder, a me ka mea hana kiʻiʻoniʻoni i nā lāʻau lapaʻau, nā huahana mālama pilikino, a me nā noi meaʻai. Hāʻawi ʻo HPC i ka solubility maikaʻi loa, ka mana viscosity, a me ka paʻa i nā hoʻonā wai.
6. ʻO Carboxymethyl Cellulose (CMC): ʻO CMC kahi wai-soluble cellulose ether i loaʻa mai ka cellulose e ka carboxymethylation. Hoʻohana nui ʻia ia e like me ka mānoanoa, stabilizer, a me ka mea hoʻopaʻa i nā huahana meaʻai, nā lāʻau lapaʻau, nā huahana mālama pilikino, a me nā noi ʻoihana. Hoʻokumu ʻo CMC i nā ʻoluʻolu maʻemaʻe, viscous a hoʻohana pinepine ʻia ma ke ʻano he mea mānoanoa i nā kīʻaha, nā lole, a me nā hoʻokuʻu waha.
7. Polyanionic Cellulose (PAC): ʻO ka PAC he cellulose ether i hoʻololi ʻia me nā hui anionic, maʻamau ka carboxymethyl a i ʻole nā ​​hui phosphonate. Hoʻohana mua ʻia ʻo ia ma ke ʻano he mea hoʻohui i ka hoʻoheheʻe ʻana i ka wai no ka ʻimi ʻaila a me ke kinoea. Kōkua ʻo PAC e hōʻemi i ka nalowale o ka wai, hoʻomaikaʻi i ka viscosity, a hoʻopaʻa i ka lepo wili ma lalo o nā kūlana kiʻekiʻe a me ke kaomi kiʻekiʻe.

Hāʻawi kēia mau cellulose ethers i kahi ākea o nā hana a me nā noi ma waena o nā ʻoihana like ʻole, e hāʻawi ana i ka hana, kūpaʻa, a me ka maikaʻi o nā huahana he nui a me nā hana.
