Kev txiav txim siab rau kev siv Defoamers

(1) Muaj peev xwm defoaming; zoo ua npuas ncauj tshem tawm nrog me me npaum li cas;
(2) Muaj qhov nro qis dua li qhov system raug defoamed;
(3) Tsis cuam tshuam rau cov khoom tseem ceeb ntawm qhov system raug defoamed tom qab ntxiv;
(4) Insoluble nyob rau hauv lub cev defoamed thiab tsis yooj yim solubilized los ntawm surfactants nyob rau hauv lub system;
(5) Qhov sib npaug ntawm qhov sib npaug zoo;
(6) Chemically ruaj khov; tsis hnov ​​​​mob los yog degrade nyob rau hauv nruab nrab yog defoamed;
(7) Zoo diffusivity thiab permeability; pom qhov zoo sib kis coefficient nyob rau hauv qhov nruab nrab foaming thiab kis tau sai heev nyob rau hauv lub npuas nto;
(8) Ua haujlwm kub zoo; tsis poob kev ua haujlwm ntawm qhov kub thiab txias;
(9) Cov roj zoo solubility thiab permeability;
(10) Kev nyab xeeb siab ntawm lub cev hauv lub cev raug defoamed; tus defoamer nws tus kheej tsis yog - tshuaj lom lossis tsis muaj tshuaj lom;
(11) Tsawg Tshuaj Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), thiab Total Oxygen Demand (TOD);
(12) Kev ruaj ntseg zoo;
(13) Ntev- cov nyhuv defoaming ntev (qee qhov defoamers ua sai sai tab sis poob kev ua haujlwm dhau sijhawm);
(14) Tus nqi qis;
(15) Tsis ua kom lub ntsej muag viscosity ntawm surfactant aqueous daws.
