Ndeipi basa rehec mupende latex pendi


Nguva yekutumira: Feb-07-2023

HEC ine basa rekukora uye kuvandudza simba rekusimba remachira mumapende e latex.

HEC (Hydroxyethyl cellulose) ipolmer inonyungudika nemvura ine yakanaka viscosity kugadziriswa, inonyungudika mumvura uye organic solvents, uye inogona kugadzira emulsions yakagadzikana mumvura.Iyo ine yakanakisa halogen kuramba, kupisa uye alkali kuramba, uye yakanyanya kugadzikana kwemakemikari.HEC inoshandiswa kuvandudza viscosity yependi yelatex, kudzikamisa zvimiro zvefomula, kudzivirira kusangana kwependi yelatex, kunatsiridza kunamatira, kusimba kwesimba, kuchinjika uye kupfeka kuramba kweiyo firimu yekupfeka, inova chikamu chehunyanzvi chekuvandudza yemhando yepamusoro latex pendi.

Basa guru reHEC nderekuvandudza ma mechanical properties yejasi.Inogona zvakare kushandiswa senge anti-sedimentation agent, preservative kana anti-viscosity agent.Pasina HEC kusungirirwa, inogona kunyatsowedzera viscoelasticity yekuputira, kuwedzera simba rekusimba uye kushanduka kwekuvhara, uye kubvisa shrinkage uye kuputika kwefirimu.

Hydroxyethyl cellulose inopa yakanakisa yekubatisa zvivakwa zve latex coating, kunyanya yakakwirira PVA machira.Kana iyo yekupfeka yakakora, flocculation haizoitike.

Hydroxyethyl cellulose ine yakakwira thickening maitiro.Inogona kuderedza dosi, kuvandudza hupfumi hwefomula, uye kugadzirisa kukwesha kuramba kwejasi.

Iyo aqueous solution yehydroxyethyl cellulose haisi yeNewtonian, uye zvinhu zvemushonga zvinonzi thixotropy.

Mune iyo static state, iyo yekubikira system inoramba yakakora uye yakavhurika mushure mekunge chigadzirwa chanyungudika zvachose.

Mune yakadururwa mamiriro, sisitimu inochengetedza mwero dhigirii ye viscosity, ichiita kuti chigadzirwa ive nemhando yepamusoro yemvura, uye haina kupfava.

Mune brashi uye roll coating, chigadzirwa chiri nyore kupararira pane substrate.Yakanakira kuvaka.Panguva imwecheteyo, ine yakanaka splash kuramba.Kana iyo yekuputira yapedzwa, iyo viscosity yehurongwa inodzoserwa pakarepo, uye iyo yekupfeka inokurumidza kuburitsa kuyerera kwakaturika.
