Kev txiav txim siab los ntawm tus yam ntxwv ntawm tus neeg saib xyuas, cov neeg feem ntau xaiv trichlorotrifluoroethane (CFC-113) thiab methyl chloroform ua cov khoom tseem ceeb ntawm tus neeg saib xyuas.CFC-113 muaj qhov zoo ntawm kev ua haujlwm siab degreasing, muaj zog dissolving lub zog ntawm flux residue, tsis yog- toxic, non-flammable thiab non-explosive, yooj yim rau evaporate, tsis muaj corrosion ntawm Cheebtsam thiab PCBs, thiab ruaj khov kev ua tau zoo.Tau ntev, nws tau raug suav hais tias yog cov kuab tshuaj zoo tshaj plaws rau kev ntxuav tom qab muag ntawm cov khoom siv hauv Circuit Court board.
Txawm li cas los xij, nyob rau xyoo tas los no, nws tau pom tias CFC-113 muaj kev puas tsuaj rau cov txheej txheem ozone nyob rau hauv qhov siab.Txhawm rau kom tsis txhob muaj kev puas tsuaj ntawm lub ntiaj teb ib puag ncig, cov kev hloov pauv rau CFC tau tsim, uas feem ntau yog peb hom hauv qab no.
1. Txhim kho CFC.Cov kuab tshuaj no yog nyob rau hauv chlorofluorocarbon molecule qhia hydrogen atoms los txhawb nws muaj peev xwm nyob rau hauv cov huab cua nyob rau hauv lub ceev ntawm decomposition, kom txo tau kev puas tsuaj rau lub ozone txheej, raws li kev kwv yees, tsuas yog hais txog 1/10 ntawm CFC, qhov no CFC lwm txoj kev tov nrog HCFC.
2. semi-aqueous tu hnyav.Cov yam ntxwv los ntawm ob qho tib si muaj peev xwm yaj rosin, tab sis kuj yaj hauv dej, feem ntau yog cov kuab tshuaj terpene thiab hydrocarbon sib tov ntawm cov kuab tshuaj.Terpene cov kuab tshuaj yog tsim los ntawm hydrocarbons thiab organic acids, nws tuaj yeem ua biodegradable, yuav tsis rhuav tshem cov txheej txheej ozone, tsis muaj tshuaj lom, tsis muaj corrosive, flux residues muaj peev xwm yaj.Hydrocarbon sib tov cov kuab tshuaj feem ntau yog tsim los ntawm hydrocarbon sib tov thiab muaj cov polar thiab tsis-polar Cheebtsam, txhim kho muaj peev xwm yaj ntau yam kuab paug.Semi-aqueous cleaners yog tam sim no dav suav hais tias yog qhov pheej hmoo tshaj lwm cov kuab tshuaj.
3. Aqueous cleaners.Nws muaj pes tsawg leeg yog cov polar dej-raws li inorganic tshuaj, feem ntau yog siv saponifier thiab vuam seem "saponification cov tshuaj tiv thaiv" los tsim cov dej-soluble fatty acid ntsev, thiab tom qab ntawd yaug nrog dej deionised.Cov khoom siv tu no yog lwm txoj hauv kev zoo rau CFC cov kuab tshuaj ntxuav, feem ntau yog siv rau kev tu cov khoom siv tsawg.
Tam sim no, tus neeg saib xyuas kev ntxuav yog txuas ntxiv mus rau qhov tsis muaj tshuaj lom, tsis rhuav tshem cov txheej txheem atmospheric ozone, tsis muaj kev puas tsuaj rau ib puag ncig ntuj, yuav tsis tsim kev phom sij tshiab, tuaj yeem ntxuav tau zoo nyob rau hauv cov kev taw qhia ntawm high-density SMA. .
Zhejiang NeoDen Technology Co., LTD., nrhiav tau nyob rau hauv 2010, yog ib tug kws chaw tsim tshuaj paus tshwj xeeb nyob rau hauv SMT xaiv thiab qhov chaw tshuab, reflow cub, stencil printing tshuab, SMT ntau lawm kab thiab lwm yam SMT khoom.Peb muaj peb tus kheej R & D pab neeg thiab tus kheej lub Hoobkas, ua kom zoo dua ntawm peb tus kheej nplua nuj kev paub R & D, kev cob qhia zoo, tau txais lub koob npe nrov los ntawm cov neeg siv khoom thoob ntiaj teb.
Hauv kaum xyoo no, peb tus kheej tsim NeoDen4, NeoDen IN6, NeoDen K1830, NeoDen FP2636 thiab lwm yam khoom siv SMT, uas muag zoo thoob plaws ntiaj teb.Txog tam sim no, peb tau muag ntau dua 10,000pcs tshuab thiab xa tawm mus rau ntau dua 130 lub teb chaws thoob ntiaj teb, tsim kom muaj lub koob npe nrov hauv kev ua lag luam.Hauv peb lub ntiaj teb Ecosystem, peb koom tes nrog peb tus khub zoo tshaj plaws los xa cov kev pab cuam muag khoom ntau dua, kev ua haujlwm siab thiab kev txhawb nqa zoo.
