Hydroxyethyl cellulose (HEC)he ma, he kowhai marama ranei, he hongi, he kikokore, he paura totoka ranei, he mea whakarite ma te tauhohenga whakaetere o te cellulose alkaline me te ethylene oxide (te chlorohydrin ranei).Ko nga etera cellulose wairewa nonionic.I tua atu i te matotoru, te whakatarewa, te here, te maanu, te hanga kiriata, te marara, te pupuri wai me te whakarato colloid tiaki, kei a ia nga ahuatanga e whai ake nei:
1. He wairewa te HEC i roto i te wai wera, te wai matao ranei, te teitei o te wera, te koropupuke ranei me te kore ua, na reira he maha nga ahuatanga o te whakarewatanga me te pokey, me te waiariki kore;
2. Karekau he katote, ka taea te noho tahi me te tini o etahi atu polymers wairewa-wairewa, surfactants, me nga tai.He pai rawa atu te whakamaarata colloidal mo nga otinga electrolyte teitei;
3. Ko te kaha o te pupuri i te wai e rua ake te teitei o te methyl cellulose, a he pai ake te whakahaere o te rere.
4. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea kino rawa atu, engari ko te kaha o te colloid tiaki te kaha.Na te mea he pai nga ahuatanga o te matotoru, te aukati, te whakamarara, te whakaemulsifying, te piri, te hanga kiriata, te tiaki i te makuku me te whakarato colloid tiaki, kua whakamahia nuitia te HEC i roto i te torotoro hinu, te paninga, te hanga, te rongoa, te kai, te kakano, te pepa me te polymer Polymerization. me etahi atu mara.
Whakatupato:
I te mea he paura, he totoka ranei te cellulose hydroxyethyl cellulose, he ngawari ki te hapai me te memeha i roto i te wai mena ka arohia nga mea e whai ake nei.te
1. I mua, i muri i te taapiri i te hydroxyethyl cellulose, me whakaoho tonu kia tino marama, kia marama te otinga.te
2. Me ata tatari ki roto i te taika ranu, kaua e whakauru tika i te nui o te hydroxyethyl cellulose, te hydroxyethyl cellulose ranei kua hanga kapia me nga poi ki roto i te tank whakaranu.te
3. Ko te pāmahana wai me te uara PH i roto i te wai he tino hononga ki te whakakorenga o te hydroxyethyl cellulose, no reira me aro nui.te
4. Kaua e taapiri etahi matū kawakore ki te ranunga i mua i te whakamahanatanga o te paura hydroxyethyl cellulose i roto i te wai.Ko te whakanui ake i te uara PH i muri i te whakamahana ka awhina i te memeha.te
5. I te mea e taea ana, taapirihia he kaihoko anti-fungal i te wa e taea ai.te
6. I te wa e whakamahi ana i te hydroxyethyl cellulose teitei, ko te kukū o te waipiro whaea kia kaua e teitei ake i te 2.5-3%, mena ka uaua te hapai i te waipiro whaea.Ko te hydroxyethyl cellulose i muri mai i te rongoa he mea ngawari ki te hanga kapia, awheawhe ranei, kare ano hoki e hanga i nga colloid porowhita korekore i muri i te taapiri wai.
