Njira yogwiritsira ntchito defoamer kupanga mapepala

Popanga mafakitale, zithovu zambiri zovulaza zidzapangidwa, ndipo defoamer iyenera kuwonjezeredwa. Amagwiritsidwa ntchito kwambiri pochotsa thovu loyipa lomwe limapangidwa popanga latex, kukula kwa nsalu, kuwira kwa chakudya, biomedicine, zokutira, petrochemical, kupanga mapepala, kuyeretsa mafakitale ndi mafakitale ena.Emulsion ya siliconedefoamer ntchito chidziwitso: musanagwiritse ntchito kapena sampuli muyenera kusonkhezera emulsion. Emulsion yamafuta m'madzi imatha kuchepetsedwa mosasamala, koma nthawi yomweyo, kukhazikika kwa emulsion kudzachepanso kwambiri, monga stratification. Mukathira, chonde onjezerani madzi ku defoamer ndikuyambitsa pang'onopang'ono. Popeza emulsion imakhala yokhazikika pakukhazikika kwake koyambirira, emulsion yochepetsedwa iyenera kugwiritsidwa ntchito pakanthawi kochepa. Ma emulsion amakhudzidwa ndi chisanu komanso kutentha pamwamba pa 40 ° C. Dzitetezeni ku chisanu! Mafuta odzola omwe aundana amatha kuchotsedwa mosamala ku chisanu, koma ayenera kuyesedwa musanagwiritse ntchito. Oscillations wamphamvu kapena kumeta amphamvu (monga ntchito makina mpope, homogenizer, etc.) kapena oyambitsa kwa nthawi yaitali adzawononga bata la emulsion. Kuchulukitsa mamasukidwe akayendedwe a emulsion kapena kuwonjezera thickener akhoza kusintha bata la emulsion.

① Itha kuchepetsedwa ndi madzi oyera 1-3 nthawi kugwera mu dziwe lotayirira, bokosi lalitali, mauna ophatikizira ndi magawo ena kuwira; ② Kuchuluka kwa thovu la 0.01% -0.2%; ③ mankhwala ayenera kuchepetsedwa posachedwapa mu nthawi yochepa.

Mu mphero ya zamkati, defoamer nthawi zambiri amawonjezedwa mu gawo lopaka utoto ndi kutsuka, ndipo nthawi zambiri amawonjezedwa mu makina ochapira a zamkati, thickener ndi zamkati thanki. The defoamer mu pepalakupanga gawonthawi zambiri amawonjezeredwa ku bokosi lamakina otaya makina, dziwe la zamkati, zokutira ndi makina osindikizira.

Nthawi zambiri zimakhala zotsika mtengo kugwiritsa ntchito zida ziwiri zofowoka kuposa kugwiritsa ntchito chotsitsa chimodzi chochulukirapo, chomwe chimawonjezeredwa padera pamalo otalikirana. Mwachitsanzo, defoamer imodzi imawonjezedwa kutsogolo kwa womenya ndipo ina imawonjezedwa mu bokosi loyenda.
