I roto i ngā mea whakapaipai, he maha ngā matū kore tae, kore kakara, engari he iti noa ngā matū kore paitini. I tēnei rā, ka whakamōhio atu ahau ki a koutou, te hydroxyethyl cellulose, he mea tino kitea i roto i te maha o ngā mea whakapaipai, i ngā mea rānei e hiahiatia ana i ia rā.
Te Pūtau Hidroksietirīri【Te Pūtau Hidroksietirīri】
E mōhiotia ana ko (HEC) he mā, he kōwhai mā, he kore kakara, he kore paitini te muka, he paura rānei. Nā te mea he pai ngā āhuatanga o te HEC ki te whakamātotoru, ki te whakatārewatanga, ki te horapa, ki te whakaemulsifying, ki te here, ki te hanga kiriata, ki te tiaki i te makuku me te whakarato colloid tiaki, kua whānuitia te whakamahinga i roto i ngā mahi hauora me te whakapaipai.
Ngā Āhuatanga o te Hua
1. Ka wairewa te HEC i roto i te wai wera, i te wai matao rānei, ā, kāore e pupū ake i te pāmahana tiketike, i te wai kohua rānei, nā reira he whānuitia ngā āhuatanga wairewa me te matotoru, tae atu ki te kore-werawera o te wai whakapūkara;
2. Ka taea e te mea kore-ionic te noho tahi me te whānuitanga o ngā polymer wairewa-wai, ngā surfactants me ngā tote, ā, he mea whakamātotoru colloidal pai rawa atu kei roto ngā otinga dielectric kukū-teitei;
3. E rua ngā teitei ake o te kaha pupuri wai i tō te methyl cellulose, ā, he pai ake te whakahaere rere;
4. Ki te whakaritea ki te methyl cellulose me te hydroxypropyl methyl cellulose kua mōhiotia, ko te kaha marara o HEC te mea kino rawa atu, engari ko te colloid tiaki te mea tino kaha.
tūranga i roto i ngā mea whakapaipai
He rerekē te taumaha ngota o ngā mea whakapaipai, te matotoru o ngā matū taiao, ngā matū horihori me ētahi atu huānga, nō reira me tāpiri he matū whakarewa kia pai ai te mahi a ngā kai katoa. He tino whai wāhi ngā āhuatanga wairewa me te matotoru o te hydroxyethyl cellulose, ā, ka mau tonu te taurite, kia mau tonu ai te āhua taketake o ngā mea whakapaipai i ngā wā makariri me te wera. Hei tāpiri, he āhuatanga whakamakuku tōna, ā, he mea noa i roto i ngā mea whakapaipai o ngā hua whakamakuku. Ina koa, ko ngā kopare, ko ngā toner, me ētahi atu mea ka tāpirihia tata katoa.
pānga taha
Ko te Hydroxyethyl cellulose e whakamahia ana i roto i ngā mea whakapaipai, kāore he paitini ina whakamahia ana ngā whakangawari, ngā whakamātotoru, me ētahi atu. Ā, e kiia ana ko ia te hua haumaru taiao Nama 1 e EWG.
