Indlela yokusebenzisa i-defoamer yokwenza iphepha

Kwinkqubo yokuveliswa kwamashishini, amagwebu amaninzi ayingozi aya kuveliswa, kwaye i-defoamer kufuneka yongezwe. Isetyenziselwa kakhulu ukususa amagwebu anobungozi avelisiweyo kwinkqubo yokuvelisa i-latex, ubungakanani belaphu, ukuvutshelwa kokutya, i-biomedicine, i-coating, i-petrochemical, ukwenza iphepha, ukucocwa kwemizi-mveliso kunye namanye amashishini.I-silicone emulsioninqaku lokusetyenziswa kwe-defoamer: ngaphambi kokusetyenziswa okanye isampuli kufuneka uvuselele ngokupheleleyo i-emulsion. I-emulsion ye-oyile emanzini inokuhlanjululwa ngokungaqhelekanga, kodwa kwangaxeshanye, ukuzinza kwe-emulsion kuya kuncipha ngokukhawuleza, njenge-stratification. Xa uhlambulula, nceda wongeze amanzi kwi-defoamer kwaye uqhube ngokukhawuleza. Ekubeni i-emulsion iyona nto izinzile ekugxininiseni kwayo kwasekuqaleni, i-emulsion ehlanjululweyo kufuneka isetyenziswe ngexesha elifutshane. Ii-emulsions zibuthathaka kwaye zisengozini kwiqabaka kunye namaqondo obushushu angaphezu kwama-40°C. Khusela kwiqabaka! Izinto zokuthambisa ezikhenkcezisiweyo zinokususwa ngononophelo kwiqabaka, kodwa kufuneka zivavanywe phambi kokuba ziphinde zisetyenziswe. I-oscillations enamandla okanye ukucheba okuqinileyo (njengokusebenzisa ipompo yomatshini, i-homogenizer, njl.) okanye ukuvuselela ixesha elide kuya kutshabalalisa ukuzinza kwe-emulsion. Ukwandisa i-viscosity ye-emulsion okanye ukongeza i-thickener kunokuphucula ukuzinza kwe-emulsion.

① Inokuhlanjululwa ngamanzi acocekileyo amaxesha angama-1-3 ehla kwi-slurry pool, ibhokisi ephezulu, i-mesh trough kunye nezinye iindawo zamaqamza; ② Isixa senkqubo yogwebu lwe-0.01% -0.2%; ③ imveliso kufuneka ixutywe ngokukhawuleza ngexesha elifutshane.

Kwi-pulp mill, i-defoamer yongezwa ngokubanzi kwi-bleaching kunye necandelo lokuhlamba, kwaye ngokubanzi yongezwa kumatshini wokuhlamba we-pulp, i-thickener kunye ne-pulp tank. I-defoamer ephepheniicandelo lokwenzaiyongezwa ngokubanzi kwibhokisi yokuhamba yomatshini wephepha, idili yepulp, icoating kunye nesaying press.

Ngokuqhelekileyo kubiza kakhulu ukusebenzisa ii-defoamant ezimbini kunokusebenzisa inani eliphezulu le-defoamant enye, eyongezwe ngokwahlukileyo kwiindawo ezikude. Ngokomzekelo, enye i-defoamer yongezwa phambi kokubetha kwaye enye yongezwa kwibhokisi yokuhamba.
