CMC Carboxymethyl Cellulose

Whakaahuatanga Poto:

CAS: 9004-32-4

Ko te Carboxymethyl Cellulose(CMC) he waerau wairewa wairewa i ahu mai i te polymer tino nui o te ao – miro cellulose. Kei te mohiotia ano he kapia cellulose, a ko tana tote konutai he huanga nui o te cellulose.Ko nga roopu carboxymethyl kua herea (-CH2-COOH) i te taha o te mekameka waerau ka whakarewa te cellulose ki te wai.Ka rewa, ka piki ake te viscosity o te wairewa wai, te aukati me te whakaehunga, a, i te kukū teitei ake, ka tukuna he pseudo-plasticity, thixotropy ranei.Hei polyelectrolyte taiao, ka tukuna e te CMC he utu mata ki nga matūriki koretake ka taea te whakamahi ki te whakapai ake i te pumau o nga colloids wai me nga ra, ki te whakakorikori ranei.Ka whakaratohia e ia nga ahuatanga pai o te matotoru, te pupuri wai, te hanga kiriata, te rheology me te whakahinuhinu, e whakamahia nuitia ana i roto i nga kai, nga hua tiaki whaiaro, nga peita ahumahi, nga karaera, te keri hinu, nga taonga hanga etc.

Tohu Hua

Ko te Carboxymethyl cellulose (CMC) he waerau wairewa-wai-wairewa i riro mai i te cellulose.He pai rawa atu te matotoru, te whakauru, me te pupuri i te wai, ka whakamahia i roto i te whānuitanga o nga tono tae atu ki nga kai me nga taapiri whangai, nga mea whakapaipai, te whakamaroke me te herea nga apiha, nga here, nga taonga tango wai, me nga kaihoko pupuri wai.I te mea i ahu mai te rauemi mai i te cellulose taiao, ka whakaatuhia te koiora o te koiora ka taea te tahuna i muri i te whakamahinga, he mea tino pai te taiao.

Wairewa o Carboxymethyl Cellulose(CMC)

Ko te Carboxymethyl Cellulose(CMC) he matū hydrophilic māori, ā, ka marara nga matūriki konutai carboxymethyl cellulose ki te wai, ka pupuhi tonu ka memeha.
1. I raro i te ahua o te whakakorikori, ko te taapiri i te konutai cmc kia tere te whakakore.
2. I raro i te ahua o te whakamahana, ko te taapiri i te konutai cmc marara ka taea te whakanui ake i te tere rewa, engari ko te pāmahana whakamahana e kore e teitei rawa, e tika ana i roto i te 50-60°C.
3. Mena ka whakamahia ma te whakakotahi ki etahi atu mea, tuatahi whakaranuhia nga totoka katahi ka memeha, a ma tenei ara, ka taea hoki te whakakaha ake i te tere rewa.
Tāpirihia he momo whakarewa pararopi e kore e whakarewahia ki te konutai cmc engari ka whakarewahia ki te wai penei i te waiwaro me te glycerin katahi ka memeha, no reira ka tere te tere o te otinga.
