Kodi Makhalidwe a PCB Oyeretsa Ndi Chiyani?

Poganizira za mawonekedwe a woyeretsa, anthu nthawi zambiri amasankha trichlorotrifluoroethane (CFC-113) ndi methyl chloroform ngati chinthu chachikulu choyeretsera. chapoizoni, chosayaka ndi chosaphulika, chosavuta kusungunuka, chosawonongeka kwa zigawo ndi ma PCB, komanso kugwira ntchito mokhazikika.Kwa nthawi yayitali, yakhala ikuwoneka ngati yosungunulira yabwino yoyeretsera pambuyo pa solder ya zigawo zosindikizidwa zama board.

Komabe, m’zaka zaposachedwapa, kwapezedwa kuti CFC-113 ili ndi chiyambukiro chowononga pa ozone layer pamalo okwera.Pofuna kupewa kuwononga chilengedwe cha dziko lapansi, apangidwa zoloŵa m’malo mwa CFC, zomwe makamaka zili mitundu itatu yotsatirayi.

1. CFC yabwino.zosungunulira ili mu molekyulu chlorofluorocarbon anayambitsa maatomu wa haidrojeni kulimbikitsa ake akhoza kukhala mu mlengalenga mu liwiro la kuwonongeka, kuchepetsa kuwonongeka kwa ozoni wosanjikiza, malinga ndi kuyerekezera, kokha za 1/10 CFC, izi CFC njira njira ndi Mtengo wa HCFC.

2. theka-amadzimadzi kuyeretsa zosungunulira.Wodziwika ndi mphamvu zonse kupasuka rosin, komanso kusungunuka m'madzi, makamaka terpene solvents ndi hydrocarbon osakaniza zosungunulira.Zosungunulira za Terpene zimapangidwa makamaka ndi ma hydrocarbon ndi ma organic acid, zimatha kukhala zowonongeka, sizingawononge ozoni wosanjikiza, zotsalira zopanda poizoni, zosawononga, zotsalira za flux zimatha kusungunuka.Zosungunulira zosakaniza za hydrocarbon zimapangidwa makamaka ndi zosakaniza za hydrocarbon ndipo zimakhala ndi polar komanso zomwe sizikhala ndi polar, zomwe zimapangitsa kuti zitha kusungunula zoipitsa zosiyanasiyana.Zotsukira zosungunulira zokhala ndi madzi ochepa tsopano zimawonedwa mofala ngati zosungunulira zina zodalirika kwambiri.

3. Oyeretsa amadzimadzi.Mapangidwe ake ndi zinthu za polar zochokera m'madzi, zomwe nthawi zambiri amagwiritsa ntchito saponifier ndi zotsalira zowotcherera "saponification reaction" kuti apange mchere wamafuta osungunuka m'madzi, kenako amatsukidwa ndi madzi opanda pake.Zinthu zotsukirazi ndi njira ina yabwino yoyeretsera zosungunulira za CFC, zomwe zimagwiritsidwa ntchito kwambiri poyeretsa chigawo chochepa kwambiri.

Pakali pano, wothandizira oyeretsa akupitirizabe kukhala opanda poizoni, sawononga ozoni wosanjikiza mumlengalenga, sakhala ndi zotsatira zowononga zachilengedwe, sangabweretse zoopsa zatsopano, akhoza kutsukidwa bwino potsata SMA yapamwamba kwambiri. .

Zhejiang NeoDen Technology Co., LTD., yomwe idakhazikitsidwa mu 2010, ndi katswiri wopanga makina opangira ma SMT ndi malo, uvuni wa reflow, makina osindikizira a stencil, chingwe chopangira SMT ndi Zida zina za SMT.Tili ndi gulu lathu la R & D ndi fakitale yathu, kugwiritsa ntchito mwayi wathu olemera odziwa R&D, kupanga ophunzitsidwa bwino, adapambana mbiri yabwino kuchokera kwamakasitomala padziko lonse lapansi.

M'zaka khumizi, tidapanga NeoDen4, NeoDen IN6, NeoDen K1830, NeoDen FP2636 ndi zinthu zina za SMT, zomwe zidagulitsidwa padziko lonse lapansi.Pakadali pano, tagulitsa makina opitilira 10,000pcs ndikutumiza kumayiko opitilira 130 padziko lonse lapansi, ndikukhazikitsa mbiri yabwino pamsika.Mu Ecosystem yathu yapadziko lonse lapansi, timagwirizana ndi bwenzi lathu lapamtima kuti tipereke ntchito yotseka kwambiri yotsatsa, ukadaulo wapamwamba komanso chithandizo chaukadaulo chaluso.
