V. Organic Silicon Antifoamer
Polydimethylsiloxasane, eyaziwa nangokuthi i-abicone oil, yingxenye eyinhloko ye-silicone defoamer. Uma kuqhathaniswa namanzi kanye namafutha ajwayelekile, ukungezwani kwalo okungaphezulu kuncane, okulungele womabili uhlelo lwamagwebu olususelwa emanzini kanye nohlelo olususelwa ku-Foaming. I-Silicone Oil inomsebenzi ophakeme, i-solubity ephansi, izakhiwo zamakhemikhali ezinzile, uhla lwesicelo sokukhanya, ukuguquguquka okuphansi, okungekho emthethweni, kanye nekhono elivelele. Ukungahambi kahle kungukusebenza kokuvinjwa kobuhlungu kwe-foam.
1. I-antifoomer eqinile
I-antifoomer eqinile inezimpawu zokuqina okuhle, inqubo elula, ukuthutha okulula nokusetshenziswa okulula. Ilungele zombili isigaba se-oyili kanye nesigaba samanzi, kanye nohlobo oluphakathi lokuhlakazeka luyavelele. Isetshenziswa kabanzi emkhakheni we-foam ephansi noma i-non foam upofaza.
2. Emulsion antifoamer
Amafutha e-silicone e-emulsion defolsoamer anokuxineka okukhulu, futhi i-emulsation coffifflication inkulu kakhulu. Lapho i-emulsifier ikhethiwe ingasebenzi, izodala ukuthi umenzeli we-desouming abekwe futhi i-metamorphic ngesikhathi esifushane. Ukuqina kwe-emulsion kubaluleke kakhulu kwikhwalithi ye-ejenti yokungcolisa. Ngakho-ke, ukulungiswa kwe-emulsion uhlobo lwe-silicone defoiser kugxile ekukhetheni kwe-emulsifier. Ngasikhathi sinye, i-emulsion defosaamer inomthamo omkhulu ku-silicone defosage ngezimpawu zentengo ephansi, isilinganiso esibanzi sohlelo lokusebenza, umphumela osobala wokungcolisa, njalonjalo. Ngentuthuko yobuchwepheshe bokwakhiwa, i-emulsion defoamer izokhula kakhulu.
3. Isixazululo Antifoamer
Kuyisisombululo esenziwe ngokuqeda u-abicone uwoyela ku-solvent. Isimiso saso sokungcolisa ukuthi izakhi zikawoyela we-abicone zithwalwa nge-solvent futhi zihlakazeke ngesisombululo se-foaming. Kule nqubo, uwoyela we-silicone uzokhuza kancane kancane kumaconsi ukuqeda ukungcolisa. U-Silicone uwoyela uncibilike kuhlelo olungalungile lwe-organic solution system, njenge-polychlorohoethane, i-toluene, njll.
4. I-Olif Antifoomer
Ingxenye eyinhloko ye-DeCoamer kawoyela yi-dimethyl abicone uwoyela. Amafutha e-silicone ahlanzekile ahlanzekile awunawo umphumela wokungcolisa futhi kudingeka ahluzwe. Ukungezwani komhlaba we-silicone ofihliwe kuncipha ngokushesha, futhi inani elincane lingafinyelela ukuqhekeka kwegwebu eliqinile nokuvinjwa. Lapho uwoyela we-silicone uxutshwe nengxenye ethile yabasizi be-silica abaphathwa ngayo, kungakhiwa i-decoamer ehlanganisiwe kawoyela. I-Silicon Dioxide isetshenziswa njenge-filler, ngoba inani elikhulu lamaqembu e-hydroxyl ebusweni bayo lingathuthukisa amandla asabalalisa amafutha e-silicone ohlelweni lwe-fooming, futhi kusobala ukuthi luthuthukise impahla ye-silicone defolsor.
Ngenxa yokuthi i-ailcone oil i-lipophilic, i-silicone defouamer inomthelela omuhle kakhulu wokungcolisa kusisombululo esinyibilikayo. Kodwa-ke, lawa maphuzu kufanele anake lapho usebenzisa i-silicone defoimer:
● Ukubonakala okuphansi kwe-silicone defomer inomphumela omuhle wokungcolisa, kepha ukuphikelela kwawo kumpofu; I-viscosity ephezulu i-silicone defomer iye yehlisa umthelela omubi kodwa ukuphikelela okuhle.
● Uma i-viscosity yesisombululo se-Foaming iphansi, kungcono ukukhetha i-silicone defouamer nge-viscosity ephezulu. Ngokuphambene nalokho, ukukhuphuka kwesixazululo se-Foaming kuyinto, kungcono ukukhetha i-silicone defouamer nge-viscosity ephansi.
● Isisindo samangqamuzana se-sillicone defomer sinethonya elithile emphumeleni waso osombukayo.
● I-desoamer enesisindo esiphansi samangqamuzana kulula isabalalisa futhi ichithe, kepha ukuntuleka kokuphikelela. Ngokuphambene nalokho, ukusebenza kwe-defouming kwesisindo esiphakeme se-molecular defoamer kumpofu, futhi kunzima ukuhlukunyezwa, kepha i-solubility ayimpofu futhi ukuqina kuhle.
