Ko ngā āhuatanga matua o te hydroxyethyl cellulose he wairewa i roto i te wai matao me te wai wera, ā, kāore he āhuatanga whakapūpū. He whānuitia te whānuitanga o ngā nekehanga whakakapinga, te wairewatanga me te matotoru. Ka taea e te otinga hydroxyethyl cellulose te hanga i tētahi kiriata mārama, ā, he āhuatanga o te momo kore-ionic kāore e taunekeneke ki ngā ion, ā, he pai te hototahitanga.
①Te wairewatanga pāmahana teitei me te wai: Ki te whakatauritea ki te methyl cellulose (MC), ka wairewa noa i te wai matao, ka taea te wairewa i te hydroxyethyl cellulose ki te wai wera, ki te wai matao rānei. He whānuitia ngā āhuatanga wairewatanga me te matotoru, ā, kāore e wera te wai.
②Ātete tote: Nā tōna momo kore-ionic, ka taea te noho tahi me ētahi atu polymer wairewa-wai, surfactants me ngā tote i roto i te whānuitanga. Nō reira, ki te whakaritea ki te ionic carboxymethyl cellulose (CMC), he pai ake te ātete tote o te hydroxyethyl cellulose.
③Te pupuri wai, te whakataurite, te hanga kiriata: ko tōna kaha pupuri wai he rua te nui atu i te methyl cellulose, he pai te whakahaere rere me te hanga kiriata pai, te whakaiti i te ngaronga wai, te whakauru, te ira tiaki colloid.
Te whakamahinga o te hydroxyethyl cellulose
Ko te Hydroxyethyl cellulose he hua cellulose ether wairewa-kore-ionic, e whakamahia whānuitia ana i roto i ngā paninga whare, te hinu, te polymerization polymer, te rongoā, te whakamahinga o ia rā, te pepa me te mangumangu, ngā papanga, ngā uku, te hanga, te ahuwhenua me ētahi atu ahumahi. Kei a ia ngā mahi hei whakamātotoru, hei hono, hei whakaemulsifying, hei whakamarara me te whakaū, ā, ka taea te pupuri i te wai, te hanga i te kiriata me te whakarato i te pānga colloid tiaki. He ngāwari te wairewa i roto i te wai matao me te wai wera, ā, ka taea te whakarato i te otinga me te whānuitanga o te matotoru. Ko tētahi o ngā cellulose ethers tere ake.
1 peita rapa
Ko te Hydroxyethyl cellulose te mea whakamātotoru e whakamahia whānuitia ana i roto i ngā paninga rapa. Haunga te whakamātotoru i ngā paninga rapa, ka taea hoki e ia te whakaemulsify, te horapa, te whakau me te pupuri i te wai. He āhuatanga whakamiharo tōna pānga whakamātotoru, te whanaketanga tae pai, te āhuatanga hanga kiriata me te pumau rokiroki. Ko te Hydroxyethyl cellulose he mea hanga mai i te cellulose kore-ionic ka taea te whakamahi i roto i te whānuitanga pH whānui. He pai te hototahi ki ētahi atu rauemi o te wāhanga (pēnei i ngā tae, ngā tāpiringa, ngā whakakī me ngā tote). He pai te rheology o ngā paninga kua whakamātotoruhia ki te hydroxyethyl cellulose i ngā tere kutikuti rerekē, ā, he rūpahu. Ka taea te whakamahi i ngā tikanga hanga pēnei i te paraihe, te paninga roera, me te rehu. He pai te hanganga, kāore e ngawari ki te maturuturu, te totohu me te tauhiuhi, ā, he pai te whakataurite.
2 Te Whakapūhuitanga
Ko ngā mahi a te Hydroxyethyl cellulose he whakamarara, he whakaemulsifying, he whakatarewa me te whakau i roto i ngā wāhanga polymerization, copolymerization rānei o ngā kapia hangai, ā, ka taea te whakamahi hei colloid tiaki. Ko tōna āhuatanga he kaha te whakamarara, he "kiriata" angiangi o ngā matūriki, he rahi matūriki pai, he āhua matūriki ōrite, he momo wetewete, he pai te rere, he mārama te hua, ā, he ngāwari te tukatuka. Nā te mea ka taea te rewa i te hydroxyethyl cellulose ki te wai matao me te wai wera, ā, kāore he ira pāmahana whakapūmau, he pai ake mō ngā tauhohenga polymerization rerekē.
Ko ngā āhuatanga ā-tinana nui hei tirotiro i te kounga o te mea whakamarara ko te kukū o te mata (te āputa rānei), te kaha o te āputa me te pāmahana whakapūkara o tōna wairewa. He pai ēnei āhuatanga o te hydroxyethyl cellulose mō te whakapūkara, te whakapūkara rānei o ngā kapia hangai.
He pai te hototahitanga o te Hydroxyethyl Cellulose me ētahi atu cellulose ethers wairewa-wai me te PVA. Ka taea e te pūnaha hiato kua hangaia te whiwhi i te pānga whānui o te ako mai i ngā kaha o tētahi ki tētahi me te whakakī i ngā ngoikoretanga o tētahi. Ehara i te mea he kounga pai anake ngā hua kapia hiato, engari he whakaiti hoki i te ngaronga rauemi.
3 te keri hinu
I roto i te keri me te whakaputa hinu, ko te hydroxyethyl cellulose matotoru-teitei te nuinga e whakamahia ana hei whakakīkī mō ngā wai whakaoti me ngā wai whakaoti. Ko te hydroxyethyl cellulose matotoru-iti e whakamahia ana hei whakaiti i te ngaronga wai. I roto i ngā paru maha e hiahiatia ana mō te keri, te whakaoti, te whakapiri me te pakaru, ka whakamahia te hydroxyethyl cellulose hei whakamātotoru hei whiwhi i te rere pai me te pumau o te paru. I te wā keri, ka taea e ia te whakapai ake i te kaha kawe onepu o te paru me te whakaroa i te roa o te mahi o te mata keri. I roto i ngā wai whakaoti wāhanga totoka iti me ngā wai whakapiri, ko ngā āhuatanga whakaiti wai pai o te hydroxyethyl cellulose ka ārai i te nui o te wai kei uru ki te paparanga hinu mai i te paru, ā, ka taea hoki te whakapai ake i te kaha whakaputa o te paparanga hinu.
4 Matū o ia rā
He mea hanga kiriata, he mea here, he mea whakamaroke, he mea whakaū me te mea whakamarara te Hydroxyethylcellulose i roto i ngā shampoos, i ngā rehu makawe, i ngā mea whakakore, i ngā mea whakangawari me ngā mea whakapaipai; i roto i ngā paura hopi horoi, he mea rewa anō hoki te paru.
