Kwishishini, ukuba ingxaki ye-foam ayithathi indlela echanekileyo, kuya kuba nzima kakhulu ukujongana nayo, ngoko unokuzama.iarhente yokukhupha amagwebuukwenzela ukungcolisa amagwebu, ayisiyiyo kuphela intsebenzo 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 arhente defoam lincinci kakhulu, kuphela iwaka ukuya kwamawaka amathathu angafikelela isiphumo defoaming ezicacileyo, ngoko ke isetyenziswa ngokubanzi kwiingubo ezisekelwe emanzini, ii-inki, i-inki, ivanishi, iioli zesikhumba, i-papermaking, i-coating , i-laminating glue, ipeyinti ye-latex, i-adhesives 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 amaqondo obushushu abe yi-defoam 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. Ubukhulu becala kuxhomekeke ekutshintsheni ixabiso le-pH, ukutyiwa kwetyuwa, kunye nokutshintsha ukusabela kweekhemikhali zogwebu. Umgaqo-siseko kukuba emva kokuba i-arhente yokukhupha amagwebu yongezwa kwi-arhente yokukhupha ugwebu, iimolekyuli ezikhupha amagwebu ziya kusasazwa ngokungenamkhethe kumphezulu wolwelo, zisasazwe ngokukhawuleza, kwaye zenze ifilim ebhityileyo enamaleko amabini, eya kuthi isasazeke ngakumbi, ingene, ihlasele ngokwamaleko, ngokuthe ngcembe Buyisela udonga olucekethekileyo lwegwebu lokuqala, luthintele ukubunjwa kwegwebu elinogwebu, luthintele ukubunjwa kwegwebu elinogwebu, lithintele ukubunjwa kwegwebu elinogwebu. gqabhuka.
Ngokweemeko ezahlukeneyo kunye neemfuno ezahlukeneyo zokukhupha amagwebu, khetha indlela yokukhupha amagwebu kunye nearhente yokukhupha amagwebu ekufaneleyo. Singakunika eyona defoamer ifanelekileyo kuwe, wamkelekile ukuthenga.
