Kukho iintlobo ezininziDefoamerskwaye zisetyenziswa ngokubanzi.Inkqubo "yokucinywa kwe-foam" kunye "ne-foam breaking" ye-defoamer kukuba: xa i-defoamer yongezwa kwisistim, iamolekyu zayo zisasazwa ngokungaqhelekanga kumphezulu wolwelo, zivimbela ukubunjwa kwefilimu e-elastic, oko kukuthi, ukuphelisa. isizukulwana sogwebu.Xa inkqubo ivelisa inani elikhulu le-foam, yongeza i-defoamer, iimolekyuli zayo zisasazeka ngokukhawuleza kumphezulu we-foam, zisasazeka ngokukhawuleza, zenze ifilimu encinci kakhulu, isasazeke ngakumbi, ingene kwaye ihlasele kwiileya, ngaloo ndlela ithatha indawo yodonga oluncinci. yefilimu ye-foam yokuqala.Ngenxa yoxinzelelo oluphantsi komhlaba, iqukuqela ukuya kulwelo olunoxinzelelo oluphezulu oluvelisa amagwebu, ukuze iimolekyuli ze-defoamer ezinoxinzelelo oluphantsi komhlaba ziqhubeke nokusasazeka kwaye zingene phakathi kwe-interface yolwelo lwegesi, okwenza udonga lwefilimu lube mncinci ngokukhawuleza, kwaye i-foam nayo ichaphazeleka kwindawo ejikelezileyo.Uluhlu lwefilimu olunoxinzelelo oluphezulu ludonsa ngamandla, ukwenzela ukuba uxinzelelo olujikeleze i-foam lungenakulinganiswa, olukhokelela "ekuqhekekeni kwe-foam".Iimolekyuli ze-defoamer ezingaxutywanga kwinkqubo ziya kungena kwakhona kwindawo enye ifilimu ye-foam, kwaye njalo, yonke i-foam iya kutshatyalaliswa ngokupheleleyo.
Indlela yokukhetha echanekileyoI-Antifoam
Ukuveliswa kunye nokwakhiwa kweengubo kuya kuvelisa ama-bubbles ukuya kumaqondo ahlukeneyo.Isizukulwana samaqamza sithintela inkqubela phambili egudileyo yokuvelisa kunye nokwakhiwa, kwaye kwangaxeshanye izisa iziphene kwifilimu yokwambathisa egqityiweyo.Ukukhethwa ngokuchanekileyo kwe-defoamer efanelekileyo kunokuqinisekisa inkqubela phambili eqhelekileyo yokuvelisa i-coating kunye nokwakhiwa.
Umsebenzi we-defoamer: ukutshabalalisa ifilimu ye-liquid ebusweni be-bubble, ukuthintela ukubunjwa kwe-bubble kunye nokukhuthaza ukuwa kwebhola.I-defoamer isetyenziselwa amaqamza amakhulu, kwaye i-microfoam kufuneka isetyenziswe kunye ne-degassing kunye ne-defoaming.
Iimpawu ze-Defoamer: I-defoamer ayinyibiliki phakathi, kodwa inokungena kwaye isasazeke phakathi ngendlela ye-microdroplets.Ubukhulu obusebenzayo be-microdroplets ye-defoamer ilingana nobukhulu bodonga lwe-foam.
Ukuqulunqwa kwe-Defoamer:Defoamerskwiingubo zokwakha ezisekelwe emanzini zihlulwe zibe zi-non-silicon kunye ne-silicon-containing types.NgokwesiqheloDefoamerszenziwe ngala malungu alandelayo:
Into esebenzayo: Isebenza njenge arhente yokwaphula ugwebu kunye nokukhupha ugwebu kunye noxinzelelo olusezantsi.Abameli babandakanya i-oyile yezilwanyana kunye nemifuno, i-silica ye-hydrophobic, i-alcohols ephezulu, njl.
I-arhente yokusabalalisa: I-emulsifier yokumanzisa ukuqinisekisa ukuba i-micro-droplets ekhuphayo isasazeka kwaye idibanise ifilimu ye-bubble kwaye isasazeke.Kukho non(octyl) phenol polyoxyethylene ether, isepha ityuwa njalo njalo.
Umthwali: Inceda into esebenzayo ukuba idibane nenkqubo yogwebu, kwaye kulula ukusasazeka kwinkqubo yogwebu.Ukudibanisa ezi zimbini, inoxinzelelo oluphantsi komhlaba, inceda ukucinezela amagwebu, kwaye inokunciphisa iindleko.
Iimeko ezimbini kufuneka zifezekiswe ukukhupha ugwebu: into yokungena: E=γ1+γ12-γ3 > 0, ukuqinisekisa ukuba i-defoamer ingena eludongeni lwe-foam;i-spreading factor S=γ1-v12-γ3 >0, ukuqinisekisa ukuba amathontsi e-defoamer Ukusasazwa kusasazeka kwimidiya yogwebu.
