Nā ʻano o ka cellulose ether
ʻO nā cellulose ethers kahi hui like ʻole o nā derivatives i loaʻa ma ka hoʻololi ʻana i ka cellulose kūlohelohe maoli, ka mea nui o nā paia o nā mea kanu. Hoʻoholo ʻia ke ʻano kikoʻī o ka cellulose ether e ke ʻano o nā hoʻololi kemika i hoʻokomo ʻia i ka iwi kuamoʻo cellulose. Eia kekahi mau ʻano maʻamau o ka cellulose ethers, kēlā me kēia me kāna mau waiwai kūʻokoʻa a me nā noi.
- Methyl Cellulose (MC):
- Hoʻololi Kemika: Hoʻokomo i nā hui methyl ma luna o ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki i ka wai.
- Hoʻohana ʻia i loko o nā mea hana (motar, adhesives), nā meaʻai, a me nā lāʻau lapaʻau (pale papa).
- Hydroxyethyl Cellulose (HEC):
- Hoʻololi Kemika: Hoʻokomo i nā hui hydroxyethyl ma ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki ke hoʻoheheʻe ʻia i ka wai.
- Hoʻohana maʻamau i nā mea hoʻonaninani, nā huahana mālama pilikino, nā pena, a me nā lāʻau lapaʻau.
- Hydroxypropyl Methyl Cellulose (HPMC):
- Hoʻololi Kemika: Hoʻokomo i nā hui hydroxypropyl a me methyl ma luna o ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki i ka wai.
- Hoʻohana nui ʻia i nā mea hana (motars, coatings), pharmaceuticals, a me nā huahana meaʻai.
- Carboxymethyl Cellulose (CMC):
- Hoʻololi Kemika: Hoʻokomo i nā hui carboxymethyl ma luna o ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki i ka wai.
- Hoʻohana ʻia e like me ka mānoanoa a me ka stabilizer i nā huahana meaʻai, lāʻau lapaʻau, textiles, a me nā wai wili.
- Hydroxypropyl Cellulose (HPC):
- Hoʻololi Kemika: Hoʻokomo i nā hui hydroxypropyl ma luna o ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki i ka wai.
- Hoʻohana maʻamau i nā lāʻau lapaʻau ma ke ʻano he mea hoʻopaʻa, mea hana kiʻiʻoniʻoni, a me ka mānoanoa.
- Ethyl Cellulose (EC):
- Hoʻololi Kemika: Hoʻokomo i nā hui ethyl ma luna o ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki ʻole i ka wai.
- Hoʻohana ʻia i loko o nā uhi, nā kiʻiʻoniʻoni, a me nā ʻano lāʻau lapaʻau hoʻokuʻu ʻia.
- Hydroxyethyl Methyl Cellulose (HEMC):
- Hoʻololi Kemika: Hoʻokomo i nā hui hydroxyethyl a me methyl ma ka iwi kuamoʻo cellulose.
- Nā waiwai a me nā noi:
- Hiki i ka wai.
- Hoʻohana maʻamau i nā mea hana (motar, grouts), pena, a me nā mea hoʻonaninani.
Ua koho ʻia kēia mau ʻano cellulose ethers e pili ana i kā lākou mau waiwai kikoʻī a me nā hana e pono ai no nā noi like ʻole. Hoʻoholo ka hoʻololi kemika i ka solubility, viscosity, a me nā hiʻohiʻona hana ʻē aʻe o kēlā me kēia cellulose ether, e hana ana i nā mea hoʻohui like ʻole i nā ʻoihana e like me ke kūkulu ʻana, nā lāʻau lapaʻau, nā meaʻai, nā mea hoʻonaninani, a me nā mea hou aku.
