V. I-Organic Silicon Antifoamer
I-Polydimedliloxine, ebizwa ngokuba yi-silicone oyile, yeyona nto iphambili kwi-Silicone Defoamer. Xa kuthelekiswa namanzi kunye neoyile eqhelekileyo, uxinzelelo lomphezulu lwayo luncinci, olufanelekileyo kulo lonke inkqubo esekwe emanzini kunye nenkqubo esekwe kwioyile. Ioyile yeSilicone inomsebenzi ophakamileyo, ukulinganisa okusezantsi, iipropathi zeekhemikhali ezizinzileyo, uluhlu lwesicelo lokukhanya, ukungcungcutheka okuphantsi, ukungabinatyhefu, kunye nobuchule obunetyhefu, kwaye ongenabungozi obuthathaka. Ukungaqiniseki kuyinto engalunganga yokuthintela i-foam.
I-1. I-antifoamer eqinileyo
I-antifoamer eqinileyo ineempawu zokuzinza ezifanelekileyo, inkqubo elula, iyothutho elula kunye nokusetyenziswa ngokulula. Ilungele zombini isigaba se-oyile kunye nesigaba samanzi, kwaye uhlobo lokusasazeka okuphakathi lubalasele. Isetyenziswe ngokubanzi kwintsimi ye-foam ephantsi okanye i-fing fikeng powder.
I-2. I-Emoulsion Antifoamer
Ioyile yesilika e-Emoulsion Defoamer inexinzelelo olukhulu, kwaye i-Emoulsisotion ikhulu kakhulu. Nje ukuba i-Emolsifier ikhethiwe ngokungaphazanyiswa, iya kubangela iarhente yokufaka i-DAFIng kwaye igcinwe i-metamorphic ngexesha elifutshane. Uzinzo lwe-Emoulsion lubaluleke kakhulu kumgangatho wearhente yokuphosa. Ke ngoko, ukulungiswa kwe-Emoul Spicone Defoamer igxile ekukhetheni i-Emoulsifier. Kwangelo xesha, i-Emoulsion Defoamer ineyona mitha inkulu eSilicone Defoamer ngeempawu zexabiso eliphantsi, umxholo wesicelo, njalo njalo. Ngenkqubela phambili yetekhnoloji yokuqulunqwa, uDulsion Defomer uya kuphuhlisa kakhulu.
3. Isisombululo se-antifoamer
Sisisombululo esenziwe ngeoyile ye-silicone kwi-solvent. Umgaqo wayo odangazelayo kukuba izinto zeoyile ze-silicone zezoli ziqhutywa yi-Solvent kwaye zisasazeke kwisisombululo sokukhala. Kule nkqubo, ioyile ye-silicone iya kuthi iveze ngokuthe ngcembe kumathontsi ukugqibezela ukudimaza. Ioyile ye-Silicone inyibilikisiwe kwinkqubo engaqhelekanga ye-alcychloc, enjenge-polyctchloethane, i-toluene, njl njl.
4. I-Antifoamer
Eyona nto iphambili kwi-oyile ye-oili ooli yi-dimthyl asilicone oli. I-DIMETHYL Silicone oli ayinasiphumo esibi kwaye kufuneka ikhutshelwe. Uxinzelelo lomphezulu we-silicone incipha ngokukhawuleza, kwaye isixa esincinci sinokufumana i-foam eyomeleleyo kunye ne-infinit. Xa ioyile ye-silicone ixutywe nenqanaba elithile lokuncedisa nge-hydrophoves, i-damomer yeoyile ingenziwa. I-Silicon Dioxide isetyenziswa njenge-fililler, kuba inani elikhulu lamaqela alo lwe-hydroxyl kumphezulu wayo unokuphucula amandla okusasaza kweoyile ye-silsicon, kunye nokuyiphucula ipropathi yokufaka i-silicone defoamer.
Kuba ioyile yesilika yi-lipophilic, i-silicone defomer inefuthe elibonakalayo elihle kakhulu kwisisombululo seoyile. Nangona kunjalo, la manqaku kufuneka anikelwe ingqalelo xa usebenzisa i-silicone defoamer:
● I-vifosity ephantsi uDesicone Defoamer unefuthe lokufaka idayala, kodwa ukuzingisa kwawo lihlwempu; I-vifosity ye-visicone defomer inefuthe elidimayo elicothayo kodwa ukuzingisa okuhle.
. Ngokuchasene noko, ukuphakama kwe-viscofity yesisombululo se-fiam, kungcono ukukhetha i-Silicone Defoamer nge-viscofity esezantsi.
● Ubunzima be-molecular silicone defoamer inefuthe elithile kwisiphumo sayo esidalayo.
● UDefoamer onesisindo esiphantsi semolekyuli kulula ukusasaza nokunyibilikisa, kodwa ukungazi. Ngokwahlukileyo koko, ukusebenza okungafanelekanga kwemolekyuli ephezulu yemolekyuli i-Defoamer ihlwempu, kwaye i-erulsation inzima, kodwa i-smobility ihlwempuzekile kwaye isiqu silungile.
