Whakaahuatanga Hua:
Ko te Hydroxyethyl cellulose (HEC) he ma, he kowhai marama ranei, he hongi, he paura kore paitini. He mea whakarite mai i te cellulose taketake me te ethylene oxide (he chloroethane ranei) ma te whakaeterera. He ether cellulose wairewa-kore. Na te mea he pai nga ahuatanga o te HEC cellulose o te matotoru, te aukati, te whakamararatanga, te emulsification, te adhesion, te hanga kiriata, te whakamarumaru o te makuku, me te whakamarumaru o nga colloids, ka whakamahia nuitia i roto i te tangohanga hinu, te paninga, te hanga, te rongoa me te kai, te kakano, te hanga pepa, me te etahi atu mara.
Taupānga:
1. Ka taea te whakakore i te paura Hydroxyethyl cellulose i roto i te wai wera me te wai matao, a ka kore e heke i te wera, i te kohua ranei. Na tera, he whanuitanga o te whakarewatanga me nga ahuatanga pokey me te kore-thermogelability.
2. Ka taea e HEC te noho tahi me etahi atu polymers wairewa-wai, surfactants, me nga tai. Ko te HEC he kaitototo koroua tino pai kei roto nga otinga dielectric kukū teitei.
3. Ko te kaha o te pupuri i te wai e rua ake te teitei o te methylcellulose, a he pai te whakahaere o te rere.
4. Ka whakaritea ki te methylcellulose me te hydroxypropylmethylcellulose, kei a HEC te kaha o te kaha o te colloid tiaki.
Ahumahi Hangahanga: Ka taea te whakamahi HEC hei kaihoko pupuri makuku me te aukati i te waahi ciment.
Ahumahi Keri Hinu: Ka taea te whakamahi hei kaitao me te kaihoko sima mo te wai mahi o te puna hinu. Ko te wai keri me te HEC ka taea te whakapai ake i te pumau o te keri i runga i tana mahi iti totoka.
Ahumahi Whakakikorua: Ka taea e te HEC te whai waahi ki te whakapakeke, te whakaemulsifying, te whakamarara, te whakapumau me te pupuri wai mo nga rawa taherapa. Kei te tohuhia e te paanga nui o te matotoru, te hora pai o te tae, te hanga kiriata, me te pumau o te rokiroki.
Pepa me te Waituhi: Ka taea te whakamahi hei kaihoko rahi i runga i te pepa me te pepa pepa, hei whakamatao me te kaitarai mo nga waituhi wai.
Nga matū o ia ra: Ko te HEC he kaihoko hanga kiriata whai hua, te whakapiri, te whakamaroke, te whakapumau me te whakamarara i roto i nga shampoos, nga makawe makawe, me nga mea whakapaipai.
Mōkī: 25 kgs / peeke ranei rite tono koe.
