Ngwa nke Hydroxyethylcellulose

Hydroxyethylcellulosea na-akpọ HEC na ụlọ ọrụ ahụ, na n'ozuzu nwere ngwa ise.

1. Maka agba mmiri latex:

Dị ka colloid nchebe, a pụrụ iji hydroxyethylcellulose mee ihe na vinyl acetate emulsion polymerization iji meziwanye nkwụsi ike nke usoro polymerization n'ọtụtụ pH ụkpụrụ. N'imepụta ngwaahịa emechara, a na-eji ihe mgbakwunye dị ka pigmenti na ihe ndị na-ejuputa na-agbasa n'otu n'otu, kwụsie ike ma na-enye mmetụta na-abawanye ụba. Enwere ike iji ya dị ka onye na-ekesa maka polymers nkwusioru dị ka styrene, acrylate, na propylene. A na-eji agba latex eme ihe nwere ike imeziwanye mkpụkọ na nhazi ọkwa.

2. Ịgbapu mmanụ:

A na-eji HEC eme ihe dị ka ihe na-eme ka ọkpụkpụ dị iche iche chọrọ maka ịkụ ala, nhazi nke ọma, ọrụ ciment na-agbaji, ka ụrọ ahụ wee nweta ezigbo mmiri na nkwụsi ike. Meziwanye ikike ibu apịtị n'oge a na-egwupụta mmiri, ma gbochie nnukwu mmiri ịbanye n'ime akwa mmanụ site na apịtị ahụ, na-eme ka ikike mmepụta nke oyi akwa mmanụ guzosie ike.

3. Maka ihe owuwu ụlọ na ihe eji ewu ụlọ:

N'ihi ikike njigide mmiri ya siri ike, HEC bụ ihe na-arụ ọrụ nke ọma na ihe nkedo maka slurry ciment na ngwa agha. Enwere ike ịgwakọta ya n'ime ngwa agha iji meziwanye mmiri na ịrụ ọrụ ihe owuwu, ma nwee ike ịgbatị oge evaporation nke mmiri, melite ike mbụ nke ihe ma zere mgbawa. Ọ nwere ike imeziwanye njide mmiri ya na ike njikọta mgbe ejiri ya mee plasta, plasta bonding, na plasta putty.

4. A na-eji ncha eze:

N'ihi nguzogide nnu siri ike na nguzogide acid, HEC nwere ike hụ na nkwụsi ike nke ntanye eze. Na mgbakwunye, ncha eze adịghị mfe nkụ n'ihi njigide mmiri siri ike na ikike emulsifying.

5. Ejiri ink dabere na mmiri:

HEC nwere ike ime ka ink akọrọ ngwa ngwa na enweghị ike ime ya.
