Ethyl Hydroxyethyl Cellulose (EHEC) muPepa Coating Colors

Ethyl hydroxyethyl cellulose (EHEC) i polymer inonyungudika mumvura iyo inowanzoshandiswa muindasitiri yemapepa seyamuro yekuchengetedza uye yekudhonza mvura. Iyo inowanzowedzerwa kune pulp panguva yekugadzira mapepa ekuvandudza kuchengetwa kwemafirita uye mafibhi uye kuwedzera madhiri emvura. EHEC inogonawo kushandiswa mumapepa ekuputira mavara ekuvandudza kushanda kwekuputira uye kuwedzera kunaka kwechigadzirwa chekupedzisira.

Mapepa ekuputira mavara magadzirirwo anoiswa pabepa kuti avandudze nzvimbo dzayo dzepamusoro, sekupenya, kutsvedzerera, kupenya, uye kudhinda. Kupfeka mavara kunowanzo kuve nemusanganiswa wepigment, mabhainda, mafirita, uye ekuwedzera anoparadzirwa mumvura kuita slurry. Iyo slurry inozoiswa pabepa uchishandisa nzira dzakasiyana dzekupfekedza, senge blade coating, rod coating, kana air banga.

EHEC inowanzoshandiswa sebhainda mumapepa ekuputira mavara kuti avandudze kunamatira kune pepa uye kuwedzera simba ravo uye kusimba. Iyo inoshandiswawo seyakakora yekuvandudza viscosity uye kugadzikana kweiyo coating color, iyo inogona kubatsira kuderedza kuitika kwekuremara senge mitsetse, pinholes, uye coating voids. EHEC inogonawo kuvandudza kupenya uye kutsetseka kwepepa rakaputirwa pamusoro, izvo zvinogona kuwedzera kudhinda uye kukwezva kwekuona kwechigadzirwa chekupedzisira.

Imwe yemabhenefiti akakosha ekushandisa EHEC mumapepa ekuputira mavara ndiko kugona kwayo kuumba yakasimba, inochinjika firimu inokwanisa kutsungirira kushushikana kwekugadzira mapepa uye kuomarara kwekubata, kutumira, uye kuchengetedza. EHEC inogonawo kuvandudza kudzivirira kwemvura uye inki yekupinza zvinhu zvejasi, izvo zvinogona kuvandudza kunaka uye kusimba kwechifananidzo chakadhindwa.

Imwe mukana wekushandisa EHEC mumapepa ekuputira mavara ndeyekuenderana kwayo nezvimwe zvinoshandiswa zvinowanzoshandiswa mukuputira maumbirwo. EHEC inogona kuiswa nyore nyore mukugadzira mavara ekugadzira pasina kukanganisa kushanda kwezvimwe zvinhu zvakadai se pigment, fillers, uye dispersants. EHEC inogonawo kushandiswa pamwe chete nemamwe mabhaidha, akadai se styrene-butadiene latex (SBL) uye polyvinyl doro (PVOH), kuwedzera kushanda kwejasi.

ethyl hydroxyethyl cellulose (EHEC) i polymer inoshanda zvakasiyana-siyana inogona kushandiswa mumapepa ekuputira mavara kuvandudza mashandiro avo uye kuwedzera kunaka kwechigadzirwa chekupedzisira. EHEC inogona kuvandudza kunamatira, kusimba, uye kusimba kwejasi, pamwe nekupenya, kutsvedzerera, uye kudhinda kwepepa rakaputirwa pamusoro. Kupindirana kwayo nezvimwe zvinoshandiswa zvinowanzoshandiswa mukugadzira zvipfeko zvinoita kuti ive sarudzo inokwezva kune vanogadzira mapepa vanotarisa kuvandudza kushanda kwemavara avo ekuputira.
