Defoamerndi chinthu chokhala ndi kutsika kwapansi komanso ntchito zapamwamba zomwe zimatha kuletsa kapena kuthetsa thovu mu dongosolo. Popanga mafakitale, zithovu zambiri zovulaza zidzapangidwa, zomwe zimalepheretsa kwambiri kupita patsogolo kwa kupanga. Panthawi imeneyi, m'pofunika kuwonjezera antifoaming agents kuchotsa thovu zovulaza izi.Defoameramagwiritsidwa ntchito kwambiri ndipo angagwiritsidwe ntchito kuthetsa thovu zoipa popanga latex, nsalu sizing, zokutira, petrochemicals, papermaking, mafakitale kuyeretsa, ndi mafakitale ena.
M'malo ogwiritsira ntchitodefoamer, makasitomala ambiri adzakumana ndi vuto kutidefoamerayenera kuchepetsedwa, ndipo thickener ayenera kugwiritsidwa ntchito kupatulira. Kotero, ndi mtundu wanji wa thickener womwe ndiyenera kusankha mudefoamer?
1. Thickeners ndi kukhazikika bwino ayenera kusankhidwa. Ma thickeners ena amakhala ndi kukhuthala kwabwino panthawiyo. Komabe, idzasungunuka pakapita nthawi. Zotsatira zake, madzi adzakhala madzi ndipo emulsion adzakhala emulsion, zomwe nthawi zambiri timazitcha layering kapena demulsification, zomwe zidzakhudza kwambiri khalidwe ladefoamer.
2. Kusankha chokhuthala chosavuta kugwiritsa ntchito, zokhuthala zina ndizovuta kwambiri kugwiritsa ntchito. Iyenera kuwonjezeredwa kumadzi mu kuchuluka kwake ndikusungunuka kwa nthawi yayitali isanagwiritsidwe ntchito. kutaya nthawi. Ena amagwiritsa ntchito chophatikizira chothamanga kwambiri kuti asonkhezere kwa nthawi yayitali kuti azitha kukhuthala bwino, ndipo zokometsera zina za ufa sizikugwedezeka bwino. Padzakhala clumping chodabwitsa, zomwe zidzakhudza kwambiri mankhwala khalidwe. Choncho, ndi bwino kusankha thickener yosavuta kugwiritsa ntchito ndipo mwamsanga amasungunula ndi thickens.
3. Kusankha chowonjezera chokhala ndi khalidwe lokhazikika, zowonjezera zina zimakhala zosakhazikika, ndipo mtanda ukhoza kukhuthala bwino. Gulu likhoza kukhala losiyana kwambiri, ndipo ubwino wa mankhwalawo umakhudzidwa kwambiri ukagwiritsidwa ntchito.
4. Kusankha thickener ndi mtengo wotsika mtengo, thickeners ena ndi otsika mtengo kwambiri, koma ndalama anawonjezera ndi lalikulu, ndipo mtengo ntchito ndi mkulu. Ma thickeners ena ndi okwera mtengo, koma ndalama zowonjezera ndizochepa ndipo zotsatira zake ndi zabwino. M'malo mwake, mtengo wogwiritsira ntchito watsika kwambiri.
5. Palibe thickener yabwino, yokha yoyenera kwambiri. Kusankha thickener yoyenera kwambiri, zotsatira zabwino, zotsika mtengo kwambiri, ndi zokometsera zokometsera kwambiri pazake, m'pofunika kuyesa pang'ono ndi wogwiritsa ntchito musanatsimikizire.
6. Osasankha okwera mtengo kwambiri kapena otsika mtengo, sankhani chokhuthala choyenera kwambiri kuti chithandizire kukulitsa madzi athu.defoamer, potero kukonza bata, maonekedwe ndi khalidwe ladefoamer.
