Ko te cellulose Hydroxyethyl kounga tiketike mo te umanga whakakikorua

Whakaahuatanga Poto:

1. Ko te ahua o te HEC Hydroxyethyl cellulose kaore he reka, kaore he kakara me te kore paitini-ma ki te paura kowhai kowhai iti.

2. Ko te etion cellulose nonionic. Ko te HEC he mahi whakatipu, hanga whare, whakaweto, marara, whakapumau me te tiaki wai. Ka rewa noa i roto i te wai makariri me te wai wera hei whakarato i te whanui o te pokey pokepoke, te hanga kiriata me te whakaputa i te awangawanga colloid.

3. Ko te HEC he matotoru o te hiko hiko nui. Ko tona kaha pupuri i te wai e rua atu i te MC. He pai te whakaritenga o te rere.olmer.

Kupu Whakataki Poto:

1. Ko te ahua o te HEC Hydroxyethyl cellulose kaore he reka, kaore he kakara me te kore paitini-ma ki te paura kowhai kowhai iti.

2. Ko te etion cellulose nonionic. Ko te HEC he mahi whakatipu, hanga whare, whakaweto, marara, whakapumau me te tiaki wai. Ka rewa noa i roto i te wai makariri me te wai wera hei whakarato i te whanui o te pokey pokepoke, te hanga kiriata me te whakaputa i te awangawanga colloid.

3. Ko te HEC he matotoru o te hiko hiko nui. Ko tona kaha pupuri i te wai e rua atu i te MC. He pai ona whakaritenga rerenga.

4. Ko te peita emulsion pai e hiahia ana ki te rheology peita motuhake hei whakarite i te ahiahi pai me te whakakore i nga ara paraihe i te mata o te kiriata peita maroke. Ko te rheology e pa ana ki te rahi me te tohatoha o nga pounamu emulsion, engari ko te rahi me te tohatoha he paanga ki te punaha whakaoho me te hangarau polymerization i whakamahia i roto i te polymerization.

5. Ko te polymerization na te whakamahi i te HEC hei colloids paruru ka whakaputa i te kounga emulsion rite, kaore he rereketanga i roto i nga waahanga rereke o te emulsion: i tenei wa ka taea te whakahaere i te rahi o te emulion granule i roto i te waahanga whaiti ka waiho nga granules hei mea tino nui mo te polymerization emulsion.

6. Ko nga polymerization emulsion e whakamahia ana i te HEC hei colloid tiaki

Ko te acetate vinilate me etahi atu monopole copolymerizing pēnei i te acrylic tesin, butadiene resin para-butadiene resin ethylene etc.

7. Methyl acrylic resin me etahi atu monomer coplymerizing penei i te acrylate, butadiene me etahi atu Styrene-acrylate copolymer, styrene-butadlene copy mer, vinyl chloride-acrylate copplymer, acrylonitrile- butadiene copolmer.

Tono:

1. Ko te HEC te mea whakaranu e whakamahia nuitia ana i te peita Latex.

2. Hei taapiri i te peita Latex, kei a ia te mahi hei whakakoi i te marara, kia pumau me te pupuri i te wai Ko ona ahuatanga he tino painga o te whakakoi, me te ahua o te hu pai, te hanga kiriata me te pumau.

3. Ko te HEC he etion cellulose nonionic ka taea te whakamahi i te whānuitanga o te PH. He pai te hototahi me etahi atu taonga, peera i te karakara, te awhina, te whakakii me te tote, te pai o te mahi me te papatairite. Ehara i te mea ngawari ki te turuturu i te pupuhi me te marara. 

Mahinga Matua:

➢ Te marara ngawari, ka rewa ki te wai matao, kaore he puranga

➢ Te aukati marara tino

➢ Te whakaaetanga tae pai me te whanaketanga

➢ Pūmautanga pai

➢ Pai pūmautanga koiora. kaore he ngaronga viscosity
