ʻO wai ka mea hana i ka hydroxyethylcellulose?

ʻO ka Hydroxyethylcellulose (HEC) he polymer synthetic i hoʻohana ʻia i nā ʻoihana like ʻole no nā kumu like ʻole. ʻO ia ka polymer non-ionic, wai-soluble i loaʻa mai ka cellulose, a hoʻohana ʻia ma ke ʻano he mānoanoa, emulsifier, stabilizer, a me ka mea hoʻomaha.

Hana ʻia ʻo HEC e nā ʻoihana like ʻole, me Dow Chemical, BASF, Ashland, AkzoNobel, a me Clariant. ʻO Dow Chemical kekahi o nā mea hana nui loa o HEC, a hoʻopuka i nā māka like ʻole o HEC, me ka Dowfax a me Natrosol brand. Hoʻokumu ʻo BASF i ka brand Cellosize o HEC, ʻoiai ʻo Ashland e hana i ka brand Aqualon. Hoʻokumu ʻo AkzoNobel i nā hōʻailona Aqualon a me Aquasol o HEC, a ʻo Clariant e hana i ka brand Mowiol.

Hāʻawi kēlā me kēia ʻoihana i nā ʻano helu like ʻole o HEC, he ʻokoʻa i ke ʻano o ke kaumaha molecular, viscosity, a me nā waiwai ʻē aʻe. Hiki ke paona molecular o HEC mai ka 100,000 a 1,000,000, a hiki i ka viscosity mai 1 a 10,000 cps. ʻOkoʻa nā māka o HEC i hana ʻia e kēlā me kēia hui ma ke ʻano o ko lākou solubility, kūpaʻa, a me ka launa pū me nā mea ʻē aʻe.

Ma waho aʻe o nā mea hana nui o HEC, aia kekahi mau ʻoihana liʻiliʻi e hana i ka HEC. ʻO kēia mau hui ʻo Lubrizol, aKima Kima. Hāʻawi kēlā me kēia ʻoihana i nā ʻano helu like ʻole o HEC, ʻokoʻa i nā ʻōlelo o kā lākou waiwai.

Ma keʻano holoʻokoʻa, aia nā ʻoihana like ʻole e hana ana i ka HEC, a ʻo kēlā me kēia hui e hana i nā ʻano helu like ʻole o HEC. ʻOkoʻa nā māka o HEC i hana ʻia e kēlā me kēia hui ma ke ʻano o ko lākou kaumaha molecular, viscosity, solubility, stability, a me ka launa pū me nā mea ʻē aʻe.
