Kwishishini, ukuba ingxaki ye-foam ayithathi indlela echanekileyo, kuya kuba nzima kakhulu ukujongana nayo, ngoko unokuzama.iarhente yokukhupha amagwebuukwenzela ukungcolisa amagwebu, ayisiyiyo nje into eyenziwayo elula, kodwa nesiphumo siyabonakala.Okulandelayo, makhe sembe nzuluI-Silicone Defoamersukubona ukuba zingaphi iinkcukacha ozityesheleyo.
Ngethuba lokuveliswa kunye nokusetyenziswa kweengubo, iingxaki ze-foam zihlala zivela.Ukuba izabelo azipheliswanga ngexesha, ukuchithwa kwe-coating kuya kuchaphazeleka, kubangele iziphene zomhlaba, ukungalingani, kunye nokuqhekeka ngexesha lokubunjwa kwefilimu, ekugqibeleni kuya kubangela ukunyuka kweendleko zokuvelisa., ngoko ke kufuneka sisebenzise indlela eyongayo ukusombulula le ngxaki ukuze sifumane kwakhona ilahleko.
Kukho iintlobo ezininzi ze-defoamers, ezibandakanya i-oyile ye-mineral, i-silicone, kunye ne-polyether, njl., ezineenzuzo ezininzi ezifana noku-emulsification, ukusabalalisa lula, ukuguquguquka okunamandla, ukukhupha amagwebu kakuhle, kunye nokunyanzeliswa kwe-foam ehlala ixesha elide.Yonke enye, ayiyi kuchaphazela iipropati zokwenza ifilimu emva kokusetyenziswa, kwaye ayiyi kubangela iziphene ebusweni bepeyinti, ngakumbi kwiinkqubo zepeyinti zamanzi.
Isixa se-ejenti yokucoca i-ejenti encinci kakhulu, kuphela iwaka ukuya kwamawaka amathathu angafikelela kwisiphumo esicacileyo sokukhupha amagwebu, ngoko ke isetyenziswa ngokubanzi kwiingubo ezisekelwe emanzini, i-inki, i-inks, i-varnishes, i-oyile yesikhumba, i-papermaking, i-coating, i-laminating glue, i-latex. ipeyinti, izinto zokuncamathelisa kunye nezinye iindawo.
Okwangoku, kwingxaki yogwebu, ezi ndlela zintathu zilandelayo ziqhele ukusetyenziselwa ukukhupha amagwebu.
1. Indlela yokukhupha amagwebu ngoomatshini
I-Mechanical defoaming isetyenziswa ngokuqhelekileyo kwiimeko apho ukufudumala kuyadingeka ukuba kubangele ukuwohloka kwemveliso kunye nokuhlukana kwe-foam, njengokutshintsha koxinzelelo olukhawulezayo, ukuhlukana kwe-centrifugal yezisombululo kunye ne-foam, ukutshiza iinkqubo ze-foam ngomoya oxinyiweyo, ukuhluzwa kwe-ultrasonic, njl.
2. Indlela yokukhupha amagwebu ngokwasemzimbeni
Ngokuqhelekileyo, ukukhupha amagwebu ngokwasemzimbeni kwamkela indlela yokutshintsha ubushushu ukuba bube bugwebu kunye nokucinezela amagwebu.Njengoko iqondo lokushisa linyuka, i-viscosity yesisombululo iyancipha kwaye i-solvent iyancipha, ibangele ukuba i-foam iwa.Xa izinga lokushisa liyancipha, i-elasticity surface ye-foam iyancipha, kwaye ukushisa okuphantsi kubangela i-icing, ephazamisa isakhiwo se-foam kwaye ibangele ukuba i-foam iqhume.
3. Indlela yokukhupha amagwebu ngemichiza
Indlela yokukhupha amagwebu emichiza ixhomekeke ikakhulu ekongezweni kwe-silicone defoaming agent, eyona ndlela ifanelekileyo nesebenzayo yokukhupha amagwebu kunye ne-antifoaming phakathi kweendlela ezintathu.Ikakhulu ixhomekeke ekutshintsheni ixabiso le-pH, ukugalela ityuwa ngaphandle, kunye nokutshintsha ukusabela kweekhemikhali zogwebu.Umgaqo-siseko kukuba emva kokuba i-agent ye-defoaming yongezwa kwi-agent ye-defoaming, i-athomu ze-defoaming ziya kusasazwa ngokungaqhelekanga kumphezulu wolwelo, zisasazeke ngokukhawuleza, kwaye zenze ifilimu encinci ye-double-layer, eya kuthi isasazeke ngakumbi, ingene, kwaye zihlasele ngokwamaleko, ngokuthe ngcembe Buyisela udonga olucekethekileyo lwegwebu lokuqala, luthintele ukubunjwa kwefilimu elastiki, lutshabalalise amandla okuziphilisa ogwebu, kwaye wenze ugwebu lugqabhuke.
Ngokweemeko ezahlukeneyo kunye neemfuno ezahlukeneyo zokukhupha amagwebu, khetha indlela yokukhupha amagwebu kunye nearhente yokukhupha amagwebu ekufaneleyo.Singakunika eyona defoamer ifanelekileyo kuwe, wamkelekile ukuthenga.
