Indlela yokusebenzisa i-defoamer ekwenzeni iphepha

Enqubweni yokukhiqizwa kwezimboni, kuzokhiqizwa amagwebu amaningi ayingozi, futhi i-defoamer idinga ukwengezwa. Isetshenziswa kabanzi ukususa igwebu eliyingozi elikhiqizwe ohlelweni lokukhiqiza i-latex, ukulinganisa kwezindwangu, ukuvutshelwa kokudla, i-biomedicine, i-coating, i-petrochemical, ukwenza iphepha, ukuhlanza izimboni nezinye izimboni.I-emulsion ye-siliconeInothi lokusebenzisa i-defoamer: ngaphambi kokusetshenziswa noma isampula kudingeka uvuselele ngokugcwele i-emulsion. I-emulsion yamafutha emanzini ingahlanjululwa ngokuzenzakalelayo, kodwa ngesikhathi esifanayo, ukuzinza kwe-emulsion kuzokwehla kakhulu, njenge-stratification. Lapho uhlanza, sicela ungeze amanzi ku-defoamer bese ugovuza kancane. Njengoba i-emulsion izinzile kangcono ekugxilweni kwayo kwasekuqaleni, i-emulsion ehlanjululwe kufanele isetshenziswe phakathi nesikhathi esifushane. Ama-emulsions ayazwela futhi asengozini yesithwathwa namazinga okushisa angaphezu kuka-40°C. Vikela eqhweni! Izinto zokugcoba eziqandisiwe zingasuswa ngokucophelela kuqhwa, kodwa kufanele zihlolwe ngaphambi kokuqhubeka zisetshenziswa. Ama-oscillations aqinile noma ukugunda okuqinile (njengokusebenzisa ipompo yemishini, i-homogenizer, njll.) noma ukugqugquzela isikhathi eside kuzobhubhisa ukuzinza kwe-emulsion. Ukwandisa i-viscosity ye-emulsion noma ukwengeza i-thickener kungathuthukisa ukuzinza kwe-emulsion.

① Ingahlanjululwa ngamanzi ahlanzekile izikhathi ezingu-1-3 ku-slurry pool, ibhokisi eliphezulu, i-mesh trough nezinye izingxenye zebhamuza; ② Inani lesistimu yokukhihliza amagwebu engu-0.01% -0.2%; ③ umkhiqizo kufanele uhlanjululwe ngokushesha ngangokunokwenzeka esikhathini esifushane.

Emshinini wokugaywa, i-defoamer ivamise ukungezwa engxenyeni yokuhlanza neyokugeza, futhi ngokuvamile yengezwa emshinini wokuwasha u-pulp, i-thickener kanye ne-pulp tank. I-defoamer ephepheniisigaba sokwenzangokuvamile yengezwa ebhokisini lokugeleza lomshini wephepha, i-pulp pool, umshini wokugcoba nokulinganisa.

Ngokuvamile kubiza kakhulu ukusebenzisa ama-defoamant amabili kunokusebenzisa inani eliphakeme le-defoamant eyodwa, engezwe ngokuhlukana ezindaweni eziqhelelene. Isibonelo, i-defoamer eyodwa yengezwa phambi kwe-beater futhi enye yengezwe ebhokisini lokugeleza.
