Zomwe zimagwiritsidwa ntchito nthawi zambiri zimatha kugawidwa mu silicon (resin), ma surfactants, alkane ndi mafuta amchere molingana ndi magawo osiyanasiyana.
1, kalasi ya silicon (resin).
Silicone defoaming wothandizira amadziwikanso kuti emulsion mtundu defoaming wothandizira.Njira yogwiritsira ntchito ndikupangira silicone ndi emulsifying agent (surfactant) ndikumwaza m'madzi ndikuwonjezera kumadzi onyansa.Silika ufa ndi mtundu wina wa silicon defoamer ndi zotsatira zabwinoko defoaming.
2, kalasi ya surfactant
Mtundu wa defoaming wothandizila ndi emulsifier kwenikweni, ntchito dispersive kanthu padziko yogwira wothandizila ndicho, kupanga zinthu zomwe zimapanga thovu amakhala khola emulsification boma dispersing mu madzi, kupewa kupanga thovu potero.
3. Paraffin
Paraffin paraffin defoaming wothandizira amapangidwa ndi parafini paraffin sera kapena otumphukira ake emulsified ndi omwazika ndi emulsifying wothandizila.Ntchito yake ikufanana ndi emulsified defoaming agent ya surfactant.
4. Mafuta amchere
Mafuta amchere ndiye chotsitsa kwambiri.Kuti apititse patsogolo zotsatira, nthawi zina wothira zitsulo sopo, silikoni mafuta, pakachitsulo woipa ndi zinthu zina ntchito pamodzi.Kuphatikiza apo, kuti mafuta amchere azikhala osavuta kufalikira pamwamba pamadzi otulutsa thovu, kapena kupanga sopo wachitsulo wogawanika mumafuta amchere, nthawi zina amathanso kuwonjezera ma surfactants osiyanasiyana.
Ubwino ndi kuipa kwa mitundu yosiyanasiyana ya defoaming agents
Maminolo mafuta, amide, mowa otsika, mafuta asidi ndi mafuta asidi ester, phosphate ester ndi zina organic defoaming wothandizila kafukufuku ndi ntchito kale, ndi m'badwo woyamba wa defoaming wothandizira, ali ndi ubwino wopeza mosavuta zipangizo, mkulu chilengedwe ntchito. , mtengo wotsika wopanga;Zoyipa zake zagona pakuchepetsa kutulutsa thovu, kukhazikika kwamphamvu komanso kugwiritsa ntchito mwankhanza.
Polyether antifoaming agent ndi m'badwo wachiwiri wa antifoaming wothandizira, makamaka kuphatikiza polyether yowongoka, mowa kapena ammonia monga poyambira poyambira, zotumphukira za polyether zomwe zimatsimikiziridwa ndi gulu lachitatu.Polyether defoaming wothandizila ndi mwayi waukulu kwambiri amphamvu thovu chopinga luso, Komanso, pali poliyesidetsa defoaming wothandizila ndi kukana kutentha, kukana asidi amphamvu ndi zamchere ndi ntchito zina zabwino kwambiri;Zoyipa zake ndizochepa chifukwa cha kutentha, malo ocheperako omwe amagwiritsidwa ntchito, luso lotulutsa thovu komanso kusweka kwamadzi otsika.
Silicone defoaming wothandizira (m'badwo wachitatu wa defoaming wothandizila) ali ndi mphamvu yotsitsa thovu, amatha kutulutsa thovu mwachangu, kusinthasintha pang'ono, kusakhala ndi poizoni ku chilengedwe, kusakhala ndi mphamvu zolimbitsa thupi, kugwiritsa ntchito mosiyanasiyana ndi zabwino zina, kotero ili ndi chiyembekezo chogwiritsa ntchito komanso chachikulu. kuthekera kwa msika, koma ntchito yotsutsa thovu ndiyosauka.
Polyether yosinthidwa polysiloxane defoaming wothandizira ali ndi ubwino wa polyether defoaming agent ndi silikoni defoaming wothandizira pa nthawi yomweyo, amene ndi njira chitukuko cha defoaming wothandizira.Nthawi zina itha kugwiritsidwanso ntchito molingana ndi kusungunuka kwake, koma pakali pano pali mitundu yochepa ya zinthu zofooketsa, zomwe zikadali mu gawo la kafukufuku ndi chitukuko, ndipo mtengo wake ndi wokwera.
