Tichifunga kubva kune hunhu hwemugadziri wekuchenesa, vanhu vanowanzo sarudza trichlorotrifluoroethane (CFC-113) uye methyl chloroform sechinhu chikuru chemugadziri wekuchenesa.CFC-113 ine zvakanakira zvekudzikisa zvakanyanya, simba rekunyungudika rakasimba rekuyerera kwasara, kwete- ine chepfu, isingabatike uye isingaputike, iri nyore kufefetedza, hapana kuora kwezvikamu uye maPCB, uye kushanda kwakagadzikana.Kwenguva yakareba, yave ichionekwa seyakanakisa solvent ye post-solder yekuchenesa yeakadhindwa yedunhu bhodhi zvikamu.
Zvisinei, mumakore achangopfuura, zvakaonekwa kuti CFC-113 ine simba rinoparadza pa ozone layer munzvimbo yakakwirira.Kuitira kudzivisa kuparadzwa kwemhoteredzo yapasi, zvinotsiva CFC zvakakudziridzwa, izvo zviri zvikurukuru marudzi matatu anotevera.
1. CFC yakavandudzwa.inonyungudutsa iri mu chlorofluorocarbon molecule yakaunza maatomu ehydrogen kusimudzira ayo anogona kunge ari mumhepo mukumhanya kwekuora, kuderedza kukuvadzwa kwe ozone layer, maererano nekufungidzira, ingangoita 1/10 yeCFC, iyi CFC imwe mhinduro ine HCFC.
2. semi-aqueous yekuchenesa solvent.Inoratidzwa nekugona kunyungudutsa rosin, asi zvakare yakanyungudika mumvura, kunyanya terpene solvents uye hydrocarbon musanganiswa wezvinonyungudutsa.Terpene solvents inonyanya kuumbwa ne hydrocarbons uye organic acids, inogona kuve biodegradable, haizoparadzi iyo ozone layer, isiri-chepfu, isina-kuora, inoyerera masara ane kugona kwakanaka kwekunyungudika.Hydrocarbon musanganiswa zvinonyungudutsa zvinonyanya kuumbwa nemusanganiswa wehydrocarbon uye zvine polar uye zvisiri-polar zvikamu, zvichivandudza kugona kwekunyungudutsa kwakasiyana kwezvinosvibisa.Semi-aqueous cleaners iye zvino ave kuonekwa nevakawanda seanonyanya kuvimbisa mamwe masolvents.
3. Aqueous cleaners.Kuumbwa kwayo i polar mvura-based inorganic substances, kazhinji inoshandisa saponifier uye welding residu "saponification reaction" kugadzira mvura-inonyungudika mafuta acid munyu, uye wozosukwa nemvura yakasvibiswa.Iyi yekuchenesa zvinhu inzira inoshanda kune CFC solvent yekuchenesa, inonyanya kushandiswa kudzika-density chikamu chekuchenesa.
Parizvino, mumiriri wekuchenesa ari kuenderera mberi kune asiri-chepfu, haaparadze iyo ozone layer, haina mhedzisiro inoparadza pane yakasikwa nharaunda, haizobudisi njodzi nyowani, inogona kunyatsocheneswa munzira yekumusoro-density SMA. .
Zhejiang NeoDen Technology Co., LTD., yakavambwa muna 2010, inyanzvi inogadzira nyanzvi muSMT pick and place machine, reflow oven, stencil printing machine, SMT production line nezvimwe Zvigadzirwa zveSMT.Isu tine yedu R & D timu uye fekitori pachedu, tichitora mukana weiyo yedu yakapfuma ine ruzivo R&D, yakanyatso dzidziswa kugadzirwa, yakawana mukurumbira mukuru kubva kune vatengi pasi rese.
Mumakore gumi aya, takazvimiririra takagadzira NeoDen4, NeoDen IN6, NeoDen K1830, NeoDen FP2636 uye zvimwe zvigadzirwa zveSMT, izvo zvakatengeswa zvakanaka pasi rese.Kusvika pari zvino, tatengesa michina inodarika zviuru gumi nekutengesa kunze kwenyika dzinopfuura zana nemakumi matatu pasirese, tichigadzira mukurumbira wakanaka pamusika.Mune yedu Ecosystem yepasi rose, isu tinodyidzana nemumwe wedu wepamoyo kuendesa sevhisi inovhara yekutengesa, yepamusoro hunyanzvi uye inoshanda tekinoroji rutsigiro.
