V. Isithambisi seSilicon esingokwemvelo
I-Polydimethylsiloxane, ekwaziwa ngokuba yi-oyile ye-silicone, yeyona nto iphambili kwi-silicone defoamer. Xa ithelekiswa namanzi kunye ne-oyile eqhelekileyo, uxinzelelo lwayo lomphezulu luncinci, nto leyo efanelekileyo kwinkqubo yokufutha esekwe emanzini kunye nenkqubo yokufutha esekwe kwi-oyile. I-oyile ye-silicone inomsebenzi ophezulu, ukunyibilika okuphantsi, iipropati zeekhemikhali ezizinzileyo, uluhlu lokusetyenziswa olukhanyayo, ukungazinzi okuphantsi, ukungabi natyhefu, kunye nokukwazi ukufutha okubonakalayo. Ingxaki kukungasebenzi kakuhle kokuthintela i-foam.

1. Isithinteli sokugqwala esiqinileyo
I-Solid Antifoamer ineempawu zokuzinza okuhle, inkqubo elula, ukuthuthwa okulula kunye nokusetyenziswa okulula. Ifanelekile kuzo zombini isigaba seoyile kunye nesigaba samanzi, kwaye uhlobo lokusasazwa okuphakathi nalo luyabonakala. Isetyenziswa kakhulu kwicandelo le-low foam okanye i-non foam washing powder.

2. Isithinteli sokugqwala i-Emulsion
Ioyile ye-silicone kwi-emulsion defoamer inoxinzelelo olukhulu, kwaye i-emulsification coefficient inkulu kakhulu. Nje ukuba i-emulsifier ikhethwe ngendlela engafanelekanga, iya kubangela ukuba i-defoaming agent ibe namaleya kwaye itshintshe ngexesha elifutshane. Uzinzo lwe-emulsion lubaluleke kakhulu kumgangatho we-defoaming agent. Ke ngoko, ukulungiswa kwe-emulsion type silicone defoamer kugxile ekukhetheni i-emulsifier. Kwangaxeshanye, i-emulsion defoamer inomlinganiselo omkhulu kwi-silicone defoamer eneempawu zexabiso eliphantsi, ububanzi besicelo, isiphumo esicacileyo se-defoaming, njl. Ngokuqhubeka kwetekhnoloji yokwenza, i-emulsion defoamer iya kukhula kakhulu.

3. Isisombululo se-Antifoamer
Sisisombululo esenziwe ngokunyibilikisa ioyile ye-silicone kwi-solvent. Umgaqo wayo wokunyibilikisa ioyile ye-silicone kukuba izinto zeoyile ye-silicone zithwalwa yi-solvent kwaye zisasazwe kwisisombululo se-foam. Kule nkqubo, ioyile ye-silicone iya kujika kancinci ibe ngamathontsi ukuze igqibezele ukunyibilikisa ioyile. Ioyile ye-silicone enyibilikiswe kwinkqubo yesisombululo se-organic esingengomanzi, njenge-polychloroethane, i-toluene, njl.njl., ingasetyenziswa njengesisombululo seoyile sokunyibilikisa ioyile.

4. Isithinteli seoyile
Eyona nto iphambili kwi-oil defoamer yi-dimethyl silicone oil. I-oil ye-dimethyl silicone ecocekileyo ayinayo impembelelo yokuxovula kwaye kufuneka ixovuleke. Uxinzelelo lomphezulu we-emulsified silicone luyancipha ngokukhawuleza, kwaye inani elincinci linokwenza ukuqhekeka kwe-foam okunamandla kunye nokuthintela. Xa i-oil ye-silicone ixutywe nenxalenye ethile ye-silica assistants ephathwa nge-hydrophobically, i-oil compound defoamer inokwenziwa. I-Silicon dioxide isetyenziswa njengesizalisi, kuba inani elikhulu lamaqela e-hydroxyl kumphezulu wayo linokunyusa amandla okusasazeka kwe-oil ye-silicone kwinkqubo yokuxovula, lonyuse uzinzo lwe-emulsion, kwaye ngokucacileyo liphucule ipropathi yokuxovula ye-silicone defoamer.

Ngenxa yokuba ioyile ye-silicone ithambile, i-silicone defoamer inefuthe elihle kakhulu lokuthomalalisa isicombululo esinyibilikayo kwioyile. Nangona kunjalo, la manqaku kufuneka aqwalaselwe xa usebenzisa i-silicone defoamer:

● I-silicone defoamer ene-viscosity ephantsi inesiphumo esihle sokucoca, kodwa ayinamandla; i-silicone defoamer ene-viscosity ephezulu inesiphumo sokucoca kancinci kodwa inamandla amahle.
● Ukuba i-viscosity yesisombululo se-foam iphantsi, kungcono ukhethe i-silicone defoamer ene-viscosity ephezulu. Ngokwahlukileyo koko, xa i-viscosity yesisombululo se-foam iphezulu, kungcono ukhethe i-silicone defoamer ene-viscosity ephantsi.
● Ubunzima bemolekyuli ye-silicone defoamer enamafutha bunempembelelo ethile kwisiphumo sayo sokuxovula.
● I-defoamer enobunzima obuphantsi beemolekyuli kulula ukuyisasaza nokuyinyibilikisa, kodwa ayinayo inzondelelo. Ngokwahlukileyo koko, ukusebenza kwe-defoamer enobunzima beemolekyuli eziphezulu akukuhle, kwaye i-emulsification inzima, kodwa ukunyibilika kwayo akukuhle kwaye ukuqina kwayo kulungile.
