Ko wai te kaihanga o te hydroxyethylcellulose?

Ko te Hydroxyethylcellulose (HEC) he polymer waihanga e whakamahia ana i roto i nga momo ahumahi mo nga kaupapa rereke. He polymer kore-ionic, he wai-wairewa i ahu mai i te cellulose, a ka whakamahia hei kaihoko whakamatao, hei whakaemi, hei whakapumau, hei kaiwhakarewa.

He mea hanga a HEC e nga momo kamupene, tae atu ki a Dow Chemical, BASF, Ashland, AkzoNobel, me Clariant. Ko Dow Chemical tetahi o nga kaihanga nui rawa atu o HEC, me te whakaputa i nga momo tohu HEC, tae atu ki nga tohu Dowfax me Natrosol. Ka hangaia e te BASF te tohu Cellosize o HEC, ko Ashland te tohu Aqualon. Ka hangaia e AkzoNobel nga tohu Aqualon me Aquasol o HEC, a na Clariant te tohu Mowiol.

Ka whakaputahia e ia kamupene he momo reanga HEC, he rereke i runga i te taumaha o te ngota, te pokey me etahi atu taonga. Ko te taumaha ngota o te HEC ka taea mai i te 100,000 ki te 1,000,000, me te viscosity ka taea mai i te 1 ki te 10,000 cps. He rereke ano nga tohu o te HEC i hangaia e ia kamupene i runga i te whakarewatanga, te pumau, me te hototahi ki etahi atu kai.

I tua atu i nga kaihanga nui o HEC, he maha ano nga kamupene iti e whakaputa ana i te HEC. Ko enei kamupene ko Lubrizol, meKima Chemical. Ka whakaputahia e ia kamupene he momo reanga HEC, he rereke i runga i o raatau rawa.

I roto i te katoa, he maha nga kamupene e whakaputa ana i te HEC, a, ka mahia e ia kamupene nga momo tohu HEC. He rereke nga tohu o te HEC e mahia ana e ia kamupene i runga i te taumaha o te ngota, te pokey, te whakarewatanga, te pumau, me te hototahi ki etahi atu kai.
