Cellulose ethersHe ʻohana ia o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose, he polymer maoli i loaʻa i loko o nā paia cell o nā mea kanu. Hoʻokō ʻia ke ʻano kemika o cellulose ethers ma o ka hoʻololi kemika o cellulose ma o ka hoʻokomo ʻana i nā hui ether like ʻole. ʻO nā eter cellulose maʻamau ka Hydroxyethyl Cellulose (HEC), Hydroxypropyl Methylcellulose (HPMC), Methyl Cellulose (MC), Carboxymethyl Cellulose (CMC), a me nā mea ʻē aʻe. ʻO nā hana kemika o kēia mau cellulose ethers penei:

1. Hydroxyethyl Cellulose (HEC):
   • Hoʻokomo ʻia nā pūʻulu hydroxyethyl i loko o ka hale cellulose.
   • Hoʻolālā Kemika: [Cellulose] – [O-CH2-CH2-OH]
2. Hydroxypropyl Methylcellulose (HPMC):
   • Hoʻokomo ʻia nā hui hydroxypropyl a me methyl i loko o ka hale cellulose.
   • Hoʻolālā Kemika: [Cellulose] – [O-CH2-CHOH-CH3] a me [O-CH3]
3. Methyl Cellulose (MC):
   • Hoʻokomo ʻia nā pūʻulu methyl i loko o ka hale cellulose.
   • Hoʻolālā Kemika: [Cellulose] – [O-CH3]
4. Carboxymethyl Cellulose (CMC):
   • Hoʻokomo ʻia nā hui Carboxymethyl i loko o ka hale cellulose.
   • Hoʻolālā Kemika: [Cellulose] – [O-CH2-COOH]

Hiki ke ʻokoʻa ke ʻano kemika pololei ma muli o ke ʻano o ka hoʻololi ʻana (DS) a me nā mea ʻē aʻe e pili ana i ke kaʻina hana. ʻO ka hoʻokomo ʻana o kēia mau pūʻulu ether e hāʻawi i nā waiwai kikoʻī i kēlā me kēia cellulose ether, e like me ka hoʻoheheʻe wai, hiki ke mānoanoa, hiki ke hana kiʻiʻoniʻoni, a me nā mea hou aku.

ʻO nā mea hana o cellulose ethers e komo pū me nā hui honua a me nā ʻāpana. ʻO kekahi mau mea hana koʻikoʻi i ka ʻoihana cellulose ethers penei:

1. Kima Chemical:
   • ʻO Kima Chemical kahi hui kemika cellulose ether multinational e hana ana i nā huahana kemika like ʻole, me ka cellulose ethers.
2. Shin-Etsu:
   • ʻIke ʻia ʻo Shin-Etsu, i hoʻokumu ʻia ma Iapana, no ka hana ʻana i nā huahana kemika like ʻole, me nā derivatives cellulose.
3. Ashland Inc.:
   • ʻO Ashland kahi hui kemika kūikawā honua e hana ana i nā cellulose ethers ma waena o nā huahana ʻē aʻe.
4. CP Kelco:
   • ʻO CP Kelco kahi mea hana nui honua o nā hydrocolloids kūikawā, me ka cellulose ethers.
5. AkzoNobel:
   • He hui multinational ʻo AkzoNobel e hana ana i nā ʻano kemika kūikawā, me ka cellulose ethers.
6. Nouryon (AkzoNobel Specialty Chemicals mamua):
   • He mea hana nui ʻo Nouryon i nā mea kemika kūikawā, a ke hoʻomau nei ʻo ia i ka hoʻoilina o AkzoNobel Specialty Chemicals.

He kūlana koʻikoʻi kēia mau ʻoihana i ka mākeke cellulose ethers a hāʻawi i kahi ʻano o nā māka a me nā ʻano like ʻole e hoʻokō i nā pono ʻenehana a me nā ʻoihana. Ke hoʻohana nei i nā cellulose ethers, he mea koʻikoʻi ia e nānā i nā palapala huahana kikoʻī i hāʻawi ʻia e ka mea hana no ka ʻike kikoʻī e pili ana i nā waiwai, nā pae hoʻohana i ʻōlelo ʻia, a me nā kikoʻī ʻenehana ʻē aʻe.
