Hydroxyethyl Cellulose (HEC)
Hydroxyethyl Cellulose(HEC)
CAS:9004-62-0
Hydroxyethyl Cellulose(HEC) he wai-wairewa cellulose ether nonionic, whakamahia rite thickener, colloid tiaki, kaihoko pupuri wai me te rheology whakarerekē i roto i tono rerekē pērā i peita wai-wai, rauemi hanga, matū mara hinu me ngā hua tiaki whaiaro.Na ki ona āhuatanga makehe, pērā i te pokey tiketike, memehatanga i roto i te wai wera me te matao, me te pūmautanga matū me te ahumahi hua, HEC he maha nga hua.
Ka whakahiatotia te HEC ma te whakauru i nga roopu hydroxyethyl (-CH₂CH₂OH) ki roto i te mekameka polymer cellulose na roto i te tauhohenga etherification. Ko tenei whakarerekētanga ka whakapai ake i te wairewatanga o te wai, te kaha o te matotoru, me te hototahi ki nga hanganga rereke.

Painga Matua:
1. Pai Te Pupuri Wai: Ka awhina i te whakamaroketanga o mua i roto i nga hua me nga mea whakapaipai.
2. Pumau Puta i te Awhe pH whanui: Ka whai hua tonu i roto i nga taiao waikawa, koretake, kawakore.
3. Kore-Ionic me te Hototahi: He pai te mahi me nga matū rereke, tae atu ki te tote, te surfactants, me etahi atu waerau.
4. Whakanuia te Mahinga Hua: Ka whakapai ake i te matotoru, te whakapiri, te hanga kiriata, me nga ahuatanga whakaehunga.
5. He pai ki te taiao me te whakaheke koiora: I ahu mai i te cellulose, karekau he paitini a HEC me te pirau.
6.Whakapai ake i te Rheology me te Rere Ahuatanga: Ka taea te whakahaere i te viscosity, te aukati i te pupuhi, te sagging, me te wehenga wahanga.
Tapeke:
Ko te Hua HEC kei roto i te peeke pepa e toru nga paparanga me te peeke polyethylene o roto kua whakapakarihia, ko te taumaha kupenga he 25kg mo ia peeke.
Rokiroki:
Puritia i roto i te whare putunga maroke maroke, mawehe atu i te makuku, te ra, te ahi, te ua.
