Hav nyob ntawd! Raws li tus neeg muag khoom emulsifier, Kuv tau txais ntau cov lus nug tsis ntev los no txog seb emulsifiers puas tuaj yeem siv rau hauv vuam fluxes. Yog li, kuv xav tias kuv yuav nkag siab tob rau hauv lub ncauj lus no thiab qhia kuv cov kev xav.
Ua ntej tshaj, cia peb tham txog dab tsi emulsifiers yog. Emulsifiers yog cov khoom uas pab sib tov ob qho dej tsis sib xws, zoo li roj thiab dej, los ntawm kev txo qhov nro ntawm lawv. Lawv feem ntau siv nyob rau hauv ntau yam kev lag luam, los ntawm cov khoom noj thiab tshuaj pleev ib ce mus rau xim thiab coatings. Tab sis lawv puas tuaj yeem siv rau hauv vuam fluxes?
Zoo, cov lus teb luv luv yog yog, emulsifiers tuaj yeem siv rau hauv vuam fluxes. Txawm li cas los xij, nws tseem ceeb heev kom nkag siab txog cov cai tshwj xeeb thiab cov teeb meem ntawm kev siv emulsifiers hauv daim ntawv thov no.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv emulsifiers hauv vuam fluxes yog tias lawv tuaj yeem pab txhim kho cov ntub dej thiab sib kis ntawm cov flux. Qhov no txhais tau hais tias cov flux tuaj yeem npog qhov saum npoo ntawm cov hlau tau zoo dua, uas tuaj yeem ua rau cov vuam zoo dua. Emulsifiers tseem tuaj yeem pab txo cov viscosity ntawm flux, ua kom yooj yim rau kev thov thiab xyuas kom meej tias nws ntws sib npaug ntawm cov hlau.
Lwm qhov zoo ntawm kev siv emulsifiers hauv vuam flux yog tias lawv tuaj yeem pab txhim kho qhov ruaj khov ntawm cov flux. Welding fluxes feem ntau muaj ntau yam khoom xyaw, thiab emulsifiers tuaj yeem pab khaws cov khoom xyaw no los ntawm kev sib cais los yog tawm hauv lub sijhawm. Qhov no tuaj yeem ua kom ntseeg tau tias cov flux tseem zoo ib yam thiab siv tau thoob plaws hauv cov txheej txheem vuam.
Txawm li cas los xij, kuj tseem muaj qee qhov teeb meem cuam tshuam nrog kev siv emulsifiers hauv vuam fluxes. Ib qho ntawm cov teeb meem tseem ceeb yog cov emulsifiers tuaj yeem nkag siab rau qhov kub thiab txias. Vuam cuam tshuam nrog kub kub, thiab yog tias lub emulsifier tawg los yog decomposes ntawm qhov kub thiab txias, nws tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov flux. Tsis tas li ntawd, qee cov emulsifiers yuav hnov mob nrog lwm cov khoom xyaw hauv cov flux, uas tuaj yeem ua rau muaj teeb meem kev ua haujlwm.
Yuav kom kov yeej cov kev cov nyom no, nws yog ib qho tseem ceeb uas yuav tau xaiv txoj cai emulsifier rau daim ntawv thov vuam tshwj xeeb. Muaj ntau ntau hom emulsifiers muaj, txhua tus muaj nws tus kheej cov khoom thiab cov yam ntxwv. Qee cov emulsifiers zoo dua rau siab - daim ntawv thov kub, thaum lwm tus muaj txiaj ntsig zoo ntawm kev txhim kho ntub dej thiab sib kis. Nws tseem yog ib qho tseem ceeb uas yuav tau xav txog kev sib raug zoo ntawm emulsifier nrog rau lwm cov khoom xyaw hauv cov flux.
Ntxiv nrog rau kev xaiv cov emulsifier txoj cai, nws tseem ceeb heev uas yuav tsum siv cov nyiaj kom raug. Cov emulsifier ntau dhau tuaj yeem ua rau muaj teeb meem xws li foaming lossis viscosity ntau dhau, thaum me me yuav tsis muab cov txiaj ntsig xav tau. Nws yog ib qho tseem ceeb uas yuav tau ua raws li cov chaw tsim khoom cov lus pom zoo thiab ua qhov kev ntsuam xyuas los txiav txim siab qhov zoo ntawm emulsifier rau daim ntawv thov vuam tshwj xeeb.
Tam sim no, cia peb tham txog qee qhov piv txwv tshwj xeeb ntawm emulsifiers uas tuaj yeem siv rau hauv vuam fluxes. Ib hom emulsifier siv hauv vuam fluxes tsis yog -ionic emulsifiers. Tsis yog -ionic emulsifiers feem ntau yog tsim los ntawm kev sib xyaw ntawm fatty acids thiab cawv, thiab lawv paub txog lawv txoj kev ruaj ntseg zoo thiab sib haum nrog lwm cov khoom xyaw. Lawv tuaj yeem pab txhim kho cov ntub dej thiab nthuav tawm cov khoom ntawm cov flux, nrog rau nws txoj kev ruaj ntseg.
Lwm hom emulsifier uas tuaj yeem siv rau hauv vuam fluxes yog anionic emulsifiers. Anionic emulsifiers feem ntau yog tsim los ntawm kev sib xyaw ntawm fatty acids thiab sulfates, thiab lawv paub txog lawv cov khoom muaj zog emulsifying. Lawv tuaj yeem pab txhim kho kev ruaj ntseg ntawm cov flux thiab tiv thaiv kev sib cais ntawm cov khoom xyaw.
Ntxiv nrog rau cov hom emulsifiers no, kuj tseem muaj lwm hom tshuaj ntxiv uas tuaj yeem siv rau hauv vuam fluxes los txhim kho lawv cov kev ua tau zoo. Piv txwv li, qee qhov fluxes yuav muaj cov tshuaj antioxidants los tiv thaiv oxidation ntawm cov hlau thaum lub sij hawm vuam, los yog corrosion inhibitors los tiv thaiv cov hlau los ntawm corrosion tom qab vuam.
Yog li, txhawm rau suav nws, emulsifiers tuaj yeem siv rau hauv vuam fluxes, tab sis nws yog ib qho tseem ceeb uas yuav tau xaiv cov emulsifier txoj cai rau daim ntawv thov tshwj xeeb thiab siv cov nyiaj raug. Los ntawm kev ua li ntawd, koj tuaj yeem txhim kho qhov ntub dej thiab nthuav tawm cov khoom ntawm cov flux, nrog rau nws qhov kev ruaj ntseg, uas tuaj yeem ua rau zoo dua weld zoo.
Yog tias koj xav paub ntau ntxiv txog emulsifiers rau vuam fluxes lossis yog tias koj tab tom nrhiav tus neeg muag khoom emulsifier txhim khu kev qha, thov hu rau kuv. Kuv yuav zoo siab los tham txog koj cov kev xav tau tshwj xeeb thiab pab koj nrhiav qhov zoo emulsifier rau koj daim ntawv thov. Koj tuaj yeem tshawb xyuas4-testsdfgsdfg uakom paub ntau ntxiv txog cov khoom muaj feem xyuam.
