He wairewa te cellulose ether?

Ko nga ethers cellulose he wairewa ki te wai, koinei tetahi o o raatau ahuatanga matua.Ko te memeha wai o te cellulose ethers he hua o nga whakarereketanga matū i mahia ki te polymer cellulose taiao.Ko nga ether cellulose noa, penei i te Methyl Cellulose (MC), Hydroxyethyl Cellulose (HEC), Hydroxypropyl Methyl Cellulose (HPMC), me te Carboxymethyl Cellulose (CMC), e whakaatu ana i nga nekehanga rereke o te whakarewatanga i runga i o raatau hanganga matū motuhake.

Anei he tirohanga poto mo te memehatanga wai o etahi ether cellulose noa:

1. Methyl Cellulose (MC):
   • Ka whakarewahia te Methyl cellulose ki te wai matao, ka hanga he otinga maamaa.Ko te whakarewatanga ka awehia e te tohu o te methylation, me nga nekehanga teitei o te whakakapinga ka heke iho te wairewa.
2. Hydroxyethyl Cellulose (HEC):
   • He tino wairewa te Hydroxyethyl cellulose ki te wai wera me te wai matao.Ko tona memehatanga karekau e pa ki te pāmahana.
3. Hydroxypropyl Methyl Cellulose (HPMC):
   • He wairewa te HPMC ki te wai matao, ka piki ake te wairewa ki te teitei ake o te pāmahana.Ma tenei ka taea e koe te whakahaere i te ahua o te wairewa.
4. Carboxymethyl Cellulose (CMC):
   • Ko te Carboxymethyl cellulose he memeha noa ki te wai matao.Ka hangaia he otinga maamaa, he maamaa me te pai o te pumau.

Ko te wairewa o te cellulose ethers he taonga nui e whai waahi ana ki te whakamahi whanui i roto i nga momo tono puta noa i nga umanga.I roto i nga wairewa wai, ka taea e enei polymers te whakahaere i nga tukanga penei i te whakamakuku, te pupuhi, me te hanga kiriata, ka whai hua i roto i nga hanganga penei i te whakapiri, te paninga, te rongoa, me nga hua kai.

He mea nui kia mohiohia ahakoa ka whakarewahia te cellulose ethers ki te wai, ko nga tikanga motuhake o te whakarewatanga (pēnei i te pāmahana me te kukū) ka rereke i runga i te momo o te cellulose ether me tona tohu whakakapinga.Ka whakaarohia e nga Kaihanga me nga kaiwhakatakoto tikanga enei ahuatanga i te wa e hoahoa ana i nga hua me nga hanganga.
