Ko te HPMC he Hydroxypropyl methyl cellulose ether me HEC he hydroxyethyl cellulose ether.
Hydroxypropyl methyl cellulose (HPMC) whakataki:
1, ahumahi hanga: rite te wai me te parahu slurry māngai pupuri wai, retarder ki te hanga slurry papu.I roto i te raima, te gypsum, te paura putty me etahi atu mea hanga whare hei whakapiri, te whakapai ake i te daub me te whakaroa i te wa mahi.Ka whakamahia mo te whakapiri i te taera karaima, te mapere, te whakapaipai kirihou, te whakapiri i te kaihoko whakapakari, ka taea tonu te whakaiti i te inenga ciment.HPMCKo te mahi pupuri wai e hanga ana i te slurry i muri i te tono karekau e tika ki te maroke tere me te kapiti, ka whakarei ake i te kaha i muri i te whakapakeke.
2, hanga uku: whakamahia whānuitia hei whakapiri i roto i te hanga hua uku.
3, ahumahi whakakikorua: i roto i te ahumahi paninga rite te thickener, dispersant me stabilizer, i roto i te wai whakarewa organic ranei i te wairewa pai.Hei tango peita.
4, waituhi tā: i roto i te ahumahi mangumangu rite te thickener, dispersant me stabilizer, i roto i te wai whakarewa organic ranei i te wairewa pai.
5, kirihou: mo te hanga i te kaihoko tuku, ngawari, whakahinuhinu, etc.
6, PVC: Ko te hanga PVC hei dispersant, whakatārewatanga polymerization faaineineraa o pvc pŭpŭ tauturu matua.7, Ētahi atu: Kei te whakamahia whānuitia tenei hua i roto i te hiako, ahumahi hua pepa, hua me te tiaki huawhenua me te ahumahi pueru.
Hydroxyethyl cellulose (HEC) whakataki:
HEC Hydroxyethyl cellulose, hei ahua o te surfactant nonionic, haunga te matotoru, te maanu, te maanu, me te hanga kiriata, te marara, te wai, me te whakarato i te colloid whakamarumaru, kei a ia ano nga ahuatanga e whai ake nei:
1, HEC wairewa i roto i te wai wera, te wai matao ranei, te wera, te koropupuputanga ranei ehara i te ua, he maha nga ahuatanga o te whakarewatanga me te pokey, me te waiariki kore;
2, ka taea e ona katote-kore te noho tahi me te tini o etahi atu polymers wairewa-wairewa, surfactants, tote, he pai rawa atu te whakamaarata colloidal kei roto i te kukū teitei o te otinga electrolyte;
3, ko te kaha pupuri wai he rua teitei ake i te methyl cellulose, me te pai o te rere o te rere, 4, HEC te kaha whakamararatanga i whakaritea ki te methyl cellulose me te hydroxypropyl methyl cellulose dispersion te tino kino, engari ko te kaha o te tiaki colloidal ko te kaha rawa atu.
Te Whakamahinga: I te nuinga o te waa ka whakamahia hei maataki whakamaahuru, hei maataki whakamarumaru, hei whakapiri, hei whakapumau me te taapiri hei whakarite i te emulsion, te tiēre, te hinu, te hinu, te kaihoko horoi kanohi, te suppository me te papa, ka whakamahia ano hei kiri hydrophilic, rauemi angaahi, te whakarite i te momo anga koiwi te whakarite, ka taea hoki te whakamahi hei whakapumau i te kai.
