Malunga neeDefoamers (i-Antifoam)

Kukho iintlobo ezininzi zeIzihlazokwaye zisetyenziswa kakhulu. Inkqubo "yokucinezela i-foam" kunye "nokuqhekeka kwe-foam" ye-defoamer yile: xa i-defoamer yongezwa kwinkqubo, iimolekyuli zayo zisasazwa ngokungacwangciswanga phezu kolwelo, zithintela ukwenziwa kwefilimu elastiki, oko kukuthi, ukuphelisa ukuveliswa kwe-foam. Xa inkqubo ivelisa inani elikhulu le-foam, yongeza i-defoamer, iimolekyuli zayo zisasazeka ngokukhawuleza phezu kolwelo, zisasazeke ngokukhawuleza, zenze umaleko omncinci kakhulu wefilimu ephindwe kabini, zisasazeke ngakumbi, zingene, kwaye zingene kwiileya, ngaloo ndlela zithatha indawo yodonga olubhityileyo lwefilimu yokuqala ye-foam. Ngenxa yoxinzelelo lwayo oluphantsi lomphezulu, igeleza iye kulwelo olunoxinzelelo oluphezulu lomphezulu oluvelisa i-foam, ukuze iimolekyuli ze-defoamer ezinoxinzelelo oluphantsi lomphezulu ziqhubeke nokusasaza kwaye zingene phakathi kojongano lwegesi nolwelo, zenze udonga lwefilimu lube mncinci ngokukhawuleza, kwaye i-foam nayo ichaphazeleka ngumphezulu ojikelezileyo. Umaleko wefilimu onoxinzelelo oluphezulu utsala ngamandla, ukuze uxinzelelo olujikeleze i-foam lungalingani, nto leyo ekhokelela "ekuqhekekeni kwe-foam". Iimolekyuli ze-defoamer ezinganyibilikiyo kwinkqubo ziya kuphinda zingene kumphezulu wenye ifilimu ye-foam, kwaye yonke i-foam iya kutshatyalaliswa ngokupheleleyo.

Indlela yokukhetha echanekileyoI-Antifoam

Ukuveliswa nokwakhiwa kweengubo kuya kuvelisa iibhola ngokwamanqanaba ahlukeneyo. Ukuveliswa kweebhola kuthintela inkqubela phambili ethe tye yemveliso nokwakhiwa, kwaye kwangaxeshanye kuzisa iziphene kwifilimu yokugquma egqityiweyo. Ukukhethwa ngokuchanekileyo kwesixhobo sokucoca esifanelekileyo kunokuqinisekisa inkqubela phambili eqhelekileyo yemveliso nokwakhiwa kweengubo.

Umsebenzi we-defoamer: ukutshabalalisa ifilimu engamanzi kumphezulu we-bubble, ukuthintela ukwakheka kwe-bubble kwaye ukhuthaze ukudilika kwe-bubble. I-defoamer isetyenziselwa amaqamza amakhulu, kwaye i-microfoam kufuneka isetyenziswe kunye ne-degassing kunye ne-defoaming.

Iimpawu ze-defoamer: I-defoamer ayinyibiliki kwi-medium, kodwa ingangena ize isasazeke kwi-medium ngohlobo lwamaconsi amancinci. Ububanzi obusebenzayo be-defoamer microdroplets bulingana nobukhulu bodonga lwe-foam.

Ukwakheka kwe-Defoamer:IzihlazoIingubo zokwakha ezisekelwe emanzini zahlulwe zibe ziintlobo ezingezizo iisilicon kunye neentlobo eziqulethe isilicon.Izihlazozenziwe ngezi zinto zilandelayo:

Isithako esisebenzayo: Sisebenza njengesixhobo sokuqhekeza igwebu kunye nokususa ivumba elibi elinoxinzelelo oluphantsi lomphezulu. Abameli baquka iioyile zezilwanyana kunye nemifuno, i-silica ephobisayo, ii-alcohols eziphezulu, njl.

Isixhobo sokusasaza: I-emulsifier emanzisayo ukuqinisekisa ukuba amathontsi amancinci asusa ifoam asasazeka aze adibane nefilimu yamaqamza aze asasazeke. Kukho i-non(octyl) phenol polyoxyethylene ether, ityuwa yesepha njalo njalo.

Umthwali: Inceda into esebenzayo ukuba idibane nenkqubo yokwenza amagwebu, kwaye kulula ukuyisasaza kwinkqubo yokwenza amagwebu. Xa idibene nezi zimbini, inoxinzelelo oluphantsi lomphezulu, inceda ekucinezeleni amagwebu, kwaye inokunciphisa iindleko.

Kufuneka kuhlangatyezwane neemeko ezimbini zokucoca i-defoam: i-penetration factor: E=γ1+γ12-γ3 > 0, ukuqinisekisa ukuba i-defoam ingena eludongeni lwe-foam; i-spreading factor S=γ1-v12-γ3 >0, ukuqinisekisa ukuba i-defoam drops isasazeka kwi-foam media.
