HEC kounga whakapaipai
Ko te Hydroxyethyl cellulose, e kiia nei ko te HEC, he mā, he kōwhai mārama rānei te āhua o te muka totoka, te paura totoka rānei, kāore he paitini, kāore he reka, nō te cellulose etera kore-ionic. He ngāwari te wairewa o te Hydroxyethyl cellulose ki te wai, ka taea te wairewa i te wai matao me te wai wera, kāore he āhuatanga kirikiri o te wai, he pai te piri, he ātete wera, kāore e wairewa i roto i ngā whakarewa waro whānui. Ko te Hydroxyethyl cellulose he cellulose etera wairewa nui, tuarua ki te carboxymethyl cellulose me te hydroxypropyl methyl cellulose i te mākete o te ao.
Whakapaipai tohuHe mea hanga kiriata, he mea piri, he mea whakamaroke, he mea whakaū, he mea whakamarara hoki te HEC Hydroxyethyl cellulose i roto i te hopi horoi makawe, i ngā rehu makawe, i te mea whakakore makawe, i te tiaki makawe me ngā mea whakapaipai. Kei roto i te paura horoi he momo mea whakatau paru; ko te hopi horoi kei roto ko te hydroxyethyl cellulose, he āhuatanga mārama o te whakapai ake i te maeneene me te whakapūmau i te papanga.
Whakapaipai tohuKo te tikanga whakarite HEC Hydroxyethyl cellulose ko te whakauru i te penupenu rakau, te huruhuru miro me te hauwai konutai, kia puta ai te hua o te cellulose alkali hei rauemi mata. I muri i te pakaru ki roto i te ipu tauhohenga, i raro i ngā tikanga korehau i roto i te hauota, ka honoa ki te wai mata epoxy ethane, ka tāpirihia te etanoru, te waikawa acetic, te glyoxal, te horoi, te whakakore me te tauhohenga hononga whakawhiti o te koroheketanga. Hei whakamutunga, ka whakaritea te hua kua oti mā te horoi, te whakamaroke me te whakamaroke.
Whakapaipai tohuKo te HEC Hydroxyethyl cellulose me ōna āhuatanga whakamātotoru, here, whakaemulsion, whakatārewatanga, hanga kiriata, pupuri wai, ārai-waikura, pumau me ētahi atu āhuatanga, ka taea te whakamahi whānuitia i roto i te wai keri hinu o te kaihoko whakamātotoru, te kaiwhakamarara, te whakamātotoru peita me ngā hua waituhi, te whakapūmau, te kapia, te hanga kirihou o te kaiwhakamarara, te kaihoko rahi kakahu, ngā rauemi hanga pēnei i te sima me te gypsum here, te whakamātotoru, te kaihoko pupuri wai, te kaihoko whakatārewatanga me te surfactant mō ngā hua matū o ia rā, te kaihoko tuku pumau mō te mara rongoā, te paninga kiriata mō te papa, te aukati mō ngā rauemi angaanga, te piripiri me te whakapūmau mō te ahumahi hiko, me ētahi atu.
I te mākete o Haina, ko te whakamahinga o te hydroxyethyl cellulose e aro nui ana ki ngā paninga, ngā matū o ia rā, te hinu me ētahi atu ahumahi, ā, he iti iho i ētahi atu mara. Hei tāpiri, ko te whakaputanga o te hydroxyethyl cellulose i Haina he hua iti te utu, ā, ko tōna whakamahinga e aro nui ana ki ngā paninga iti te utu me ngā hua matū o ia rā. I te mākete utu nui, he iti te maha o ngā umanga e tika ana i Haina, kāore i te rawaka te putanga, ā, he nui te whakawhirinakitanga ki waho. Nā te whakahoutanga o te taha tuku me ngā kaupapa here tiaki taiao, kei te whakatikatika tonu, kei te whakapai ake hoki te hanganga ahumahi hydroxyethyl cellulose o Haina, ā, ka haere tonu te tere o te rohe o te mākete utu nui ki te whakapai ake i ngā rā kei te heke mai.

HECKo te Hydroxyethyl cellulose tētahi hua nui o te cellulose ether, e tuatoru ana i roto i te hanga me te hoko o te ao. He cellulose kore-ionic wairewa-wai, ka taea te whakamahi whānui i roto i te hinu, te peita, te waituhi tā, te kakahu, ngā rauemi hanga, ngā matū o ia rā, te rongoā, te hikohiko me ētahi atu ahumahi, me te whānuitanga o te whanaketanga mākete. Nā te tono, kei te piki haere te putanga o te hydroxyethyl cellulose i Haina. Nā te whakapai ake i te kai me te whakakaha ake i ngā kaupapa here tiaki taiao, kei te whanake te ahumahi ki te taumata teitei. Ko ngā pakihi kāore e taea te pupuri i te tere o te whanaketanga ā muri ake nei ka āta whakakorea.
Ko te Hydroxyethyl cellulose i roto i ngā mea whakapaipai, ngā hua tiaki kiri, ko te mahi matua o te whakangawari makawe, te kaihanga kiriata, te whakaū emulsifying, te piripiri, ko te take mōrearea ko 1, he haumaru, ka taea te okioki māia ki te whakamahi, mō ngā wahine hapu te tikanga kāore he pānga, kāore he hydroxyethyl cellulose e puta ai te hakihaki.
Ko te Hydroxyethyl cellulose he piripiri polymer hangai e whakamahia ana i roto i ngā mea whakapaipai hei whakangawari kiri, hei kaihanga kiriata me te antioxidant.
Ngā take hei aro atu i te wā e whakamahia anawhakapaipaitohu HECte hauwaitoiretiri pūtau:
1. I mua atu, ā, i muri i te tāpiritanga o te HEC hydroxyethyl cellulose kounga whakapaipai, me whakaoho tonu kia mārama rawa te otinga.
2. Tātarihia tekounga whakapaipai HECTāpirihia mārire te hydroxyethyl cellulose ki roto i te tāke whakaranu. Kaua e tāpirihia i roto i te rahinga nui, kaua hoki e tāpiri tika ki roto i te tāke whakaranu.
3. Te wairewatanga owhakapaipaitohuHECHe mārama te hononga o te hydroxyethyl cellulose ki te pāmahana wai me te uara PH, nō reira me aro nui ki tēnei.
4. Kaua rawa e tāpirihia he matū kawakore ki te ranunga i mua i te whakamataotanga o te paura hydroxyethyl cellulose ki te wai. Mā te whakanui ake i te uara PH i muri i te whakamahana ka āwhina i te memeha.
5. Ki te taea, tāpirihia te aukati harore i te wā e taea ai.
6. Ina whakamahia te HEC hydroxyethyl cellulose kounga whakapaipai matotoru teitei, kaua te kukū o te wai whaea e neke ake i te 2.5-3%, ki te kore ka uaua te whakahaere i te wai whaea. Ko te hydroxyethyl cellulose i muri i te maimoatanga he uaua ki te hanga i ngā puranga, i ngā porowhita rānei, ā, e kore hoki e hanga i ngā porowhita kore-rewa i muri i te tāpiri wai.
