Monileni apo! Pakuŵa wakupeleka emulsifier, nkhupokera mafumbo ghanandi sonosono apa ghakukhwaskana na usange emulsifiers yingagwiliskirika nchito mu kuwotcha fluxes. Ntheura, nkhaghanaghana kuti nisambirepo chomene pa nkhani iyi na kugaŵana maghanoghano ghane.
Chakwamba, tiyeni tidumbiskane ivyo vikupangika na emulsifiers. Emulsifiers ni vinthu ivyo vikovwira kusakanizga maji ghaŵiri ghambura kusazganako, nga ni mafuta na maji, mwa kuchepeska mphindano pakati pa vinthu ivi. Ŵanthu ŵakuvigwiliskira ntchito chomene mu mafakitale ghakupambanapambana, kufuma ku vyakurya na vyakujitozga m'paka ku penti na vyakuvwara. Kweni kasi vingagwiliskirika nchito pa kuwotcha?
Chabwino, zgoro lafupi ndakuti enya, emulsifiers ingagwiriskikiya nchitu mu fluxes zakuwotcha. Kweni, nchakukhumbikwa kupulikiska ivyo vikukhumbikwa na masuzgo ghakugwiriskira ncito emulsifiers mu pulogiramu iyi.
Chimoza mwa vitumbiko vikuru vya kugwiliskira ntchito emulsifiers mu welding fluxes nchakuti vingawovwira kuti flux yiŵe yakunyoweska na kuthandazgika makora. Ici cikung’anamura kuti flux yingabenekelera makora pa cisulo ico cikupangika, ndipo ici cingapangiska kuti cisulo ciŵe ciwemi. Emulsifiers zingawovwiraso kuti flux yileke kuŵa na viscosity, ndipo yikuŵa yipusu kuŵika na kuwoneseska kuti yikuchimbira mwakuyana pa chisulo.
Uwemi unyake wa kugwiliskira nchito emulsifiers mu kuwotcha fluxes ngwakuti vingawovwira kuti flux yiŵe yakukhora. Kanandi mu vyakuwotchera vikuŵa na vinthu vyakupambanapambana, ndipo vinthu ivyo vikupangiska kuti vinthu ivi vileke kupatukana panji kukhazikika para nyengo yajumphapo. Ici cingapangiska kuti maji ghalutilire kuŵa ghakuyana waka ndiposo ghakugwira nchito makora nyengo yose iyo ŵakuwotcha.
Ndipouli, paliso masuzgo ghanyake agho ghakukhwaskana na kugwiliskira nchito vyakupangira emulsifiers mu vyakuwotcha. Chimoza mwa masuzgo ghakuru nchakuti emulsifiers yingaŵa yakukhwaskika na kutentha kwakukwana. Kuwotcha kukusazgapo kutentha chomene, ndipo usange emulsifier yikunangika panji kuvunda pa kutentha uku, yingakhwaska umo flux yikugwilira ntchito. Kusazgirapo apa, vinyake ivyo vikupangika na emulsifiers vingacita vinthu na vinyake ivyo vili mu flux, ivyo vingapangiskaso kuti viŵe na suzgo la kugwira nchito.
Kuti muthereske masuzgo agha, nchakuzirwa comene kusankha emulsifier yiwemi yakugwiriskira ncito pa mulimo wa kuwotcha. Pali mitundu yakupambanapambana ya emulsifiers iyo yikusangika, ndipo chilichose chili na katundu wake wapadera na mikhaliro yake. Vinyake vyakupangika na emulsifiers vikuŵa vyakwenelera chomene kugwiliskira ntchito pa nyengo yakutentha chomene, apo vinyake vikovwira chomene pakunozga na kuthandazga. Nchakuzirwaso kughanaghanira umo emulsifier yikukolerana na vinyake ivyo vili mu flux.
Padera pa kusankha emulsifier yiwemi, nchakuzirwaso kugwiliskira nchito unandi wakwenelera. Emulsifier yinandi yingapangiska kuti paŵe masuzgo nga ni thovu panji viscosity yinandi, apo yichoko chomene yingapereka yayi vitumbiko ivyo mukukhumba. Nchakuzirwa kulondezga ivyo ŵakupanga ŵakuyowoya na kuyezga kuti ŵamanye unandi wa emulsifier uwo ungaŵapo pa ntchito yakuwotcha.
Sono, tiyeni tidumbiskane za viyelezgero vinyake vyakukhwaskana na emulsifiers ivyo vingagwiliskirika nchito mu kuwotcha fluxes. Mtundu umoza wakumanyikwa wa emulsifier uwo ukugwiriskirika nchito mu kuwotcha fluxes ni non - emulsifiers ya ionic. Non-ionic emulsifiers kanandi ŵakupangika kufuma ku kusazgako mafuta na moŵa, ndipo ŵakumanyikwa chifukwa cha kukhazikika kwawo makora na kukolerana na vinthu vinyake. Iwo ŵangawovwira kuti katundu wa flux waŵe wakunyoweska na kuthandazgika makora, ndiposo kuti waŵe wakukhora.
Mtundu unyake wa emulsifier uwo ungagwiliskirika nchito pa kuwotcha fluxes ni anionic emulsifiers. Anionic emulsifiers kanandi ŵakupangika kufuma ku kusazgako mafuta na sulfates, ndipo ŵakumanyikwa chifukwa cha nkhongono zawo zakusazgako. Iwo ŵangawovwira kuti flux yiŵe yakukhora ndiposo kuti vinthu ivyo vikusazgapo vileke kugaŵikana.
Padera pa mitundu iyi ya emulsifiers, paliso mitundu yinyake ya vyakusazgapo ivyo vingagwiliskirika nchito mu welding fluxes kuti viŵe vyakunozga. Mwaciyelezgero, mu ma flux ghanyake ghangaŵa na vinthu ivyo vikupangiska kuti cisulo cileke kuŵa na oxidation para cikuwotcha, panji vinthu ivyo vikupangiska kuti cisulo cileke kuvunda para ŵaciwotcha.
Ntheura, kuti tidumure, emulsifiers zingagwiliskirika nchito mu welding fluxes, kweni nchakuzirwa kusankha emulsifier yakukwana ya nchito yinyake na kugwiliskira nchito ndalama zakwenelera. Pakuchita nthena, mungaŵa na mwaŵi wa kunyoweska na kuthandazga katundu wa flux, ndiposo kukhazikika kwake, uko kungapangiska kuti weld yiŵe yiwemi.
Usange mukukhumba kumanya vinandi vyakukhwaskana na emulsifiers vyakupangika na welding fluxes panji usange mukukhumba munthu wakugomezgeka uyo wakupeleka emulsifier, khalani ŵakufwatuka kuniphalira. Niŵenge wakukondwa kudumbiskana namwe ivyo mukukhumba na kumuwovwirani kusanga emulsifier yakukwana yakugwiriskira ncito. Mungawonaso .4-mayesodfgsdfgkuti mumanye vinandi pa vinthu ivyo vikukhwaskana navyo.
