Nokuba sifuna ukuphuhlisa izinto zokuncamathelisa okanye ukuthenga izinto zokuncamathelisa, sihlala sibona ukuba ezinye izinto zokuncamathelisa ziya kuba nesatifikethi se-ROHS, isatifikethi se-NFS, kunye nokuqhuba kobushushu kwezinto zokuncamathelisa, ukuqhuba kobushushu, njl.njl., ezi zimele ntoni? Dibana nazo nge-siway engezantsi!
Yintoni i-ROHS?
I-ROHS ngumgangatho onyanzelekileyo ophuhliswe ngumthetho we-European Union, igama layo elipheleleyo yi-Directive on theUkuthintelwa kwezinto ezinobungozi kwizixhobo ze-elektroniki nezombane. Lo mgangatho uza kuqaliswa ngokusesikweni ngomhla woku-1 kweyeKhala ngo-2006, osetyenziswa kakhulu ukulawula imigangatho yezinto kunye neenkqubo zeemveliso ze-elektroniki nezombane, ukuze kube lula ngakumbi kwimpilo yabantu kunye nokukhuselwa kokusingqongileyo. Injongo yomgangatho kukususa i-lead, i-mercury, i-cadmium, i-hexvalent chromium, i-polybrominated biphenyls kunye ne-polybrominated biphenyl ethers kwiimveliso zeemoto neze-elektroniki, kwaye kugxilwe kumxholo we-lead akufuneki udlule kwi-1%.
Yintoni i-NSF? Yintoni i-FDA? Yintoni umahluko phakathi kwazo?
1. I-NSF sisifinyezo sesiNgesi seNational Health Foundation yase-United States, esiyintlangano engenzi nzuzo yomntu wesithathu. Isekelwe kwimigangatho yesizwe yase-United States, ngokuphuhliswa kwemigangatho, uvavanyo nokuqinisekiswa, ulawulo lwesatifikethi kunye namaxwebhu ophicotho-zincwadi, imfundo noqeqesho, uphando kunye nezinye iindlela zokuqinisekisa nokulawula iimveliso kunye nobuchwepheshe obunxulumene nempilo yoluntu kunye nokusingqongileyo.
2. Ngokuphathelele isiqinisekiso se-NSF, iNational Health Foundation (NSF) asiyoarhente karhulumente, kodwa yintlangano yenkonzo yabucala engenzi nzuzo. Injongo yayo kukuphucula umgangatho wobomi bempilo yoluntu. I-NSF yenziwe ziingcali zempilo yoluntu kunye nococeko, kuquka iiarhente zikarhulumente, iiyunivesithi, amashishini kunye namaqela abathengi. Umsebenzi wayo ugxile ekumiseni imigangatho yophuhliso kunye nolawulo lwazo zonke iimveliso ezinefuthe kucoceko, impilo yoluntu, njl. I-NSF inelebhu ebanzi evavanya zonke iimveliso ezivavanyiweyo ukuba ziyahambelana nemigangatho yokuhlolwa. Bonke abavelisi abathatha inxaxheba ngokuzithandela abaphumelela kuvavanyo lwe-NSF banokuncamathisela ilebheli ye-NSF kwimveliso kunye noncwadi malunga nemveliso ukubonisa isiqinisekiso.
3, iinkampani eziqinisekisiweyo ze-NSF, oko kukuthi, iinkampani ze-NSF, ezifana nezixhobo zasekhaya, amayeza, ukutya, impilo, imfundo njalo njalo. Le mveliso inxulumene nodidi olufanayo. I-United States Food and Drug Administration (FDA) yenye yee-arhente eziphezulu ezisekwe ngurhulumente wase-United States ngaphakathi kwiSebe lezeMpilo kunye neeNkonzo zoLuntu (DHHS) kunye neSebe lezeMpilo yoLuntu (PHS). Umbutho wesatifikethi se-NSF ngumbutho wesatifikethi samazwe ngamazwe ongenzi nzuzo, unembali yeminyaka engama-50, ikakhulu ubandakanyeka kwimigangatho yempilo yoluntu kunye nokhuseleko kunye nomsebenzi wokuqinisekiswa kwemveliso yokutya, uninzi lwemigangatho yayo yeshishini ihlonitshwa kakhulu kwihlabathi liphela, kwaye e-United States ithathwa njengomgangatho. Ngumgangatho weshishini onegunya ngakumbi kunesatifikethi se-FDA se-US Food and Drug Administration.
Yintoni i-SGS? Luthini ulwalamano phakathi kwe-SGS kunye ne-ROHS?
I-SGS sisifinyezo se-Societe Generale de Surveillance SA, esiguqulelwa ngokuthi "iGeneral Notary Firm". Yasekwa ngo-1887, okwangoku yeyona nkampani inkulu nendala yabucala yehlabathi, inkampani yangaphandle ebandakanyeka kumgangatho wemveliso kunye novavanyo lobuchwephesha. Inekomkhulu eGeneva, inamasebe angama-251 kwihlabathi liphela. I-ROHS ngumyalelo we-EU, i-SGS ingenza uvavanyo lokuqinisekiswa kwemveliso kunye nokuqinisekiswa kwenkqubo ngokwe-ROHS Directive. Kodwa eneneni, ayingongxelo ye-SGS kuphela eyamkelweyo, kukho nezinye ii-arhente zovavanyo zamaqela esithathu, ezifana ne-ITS njalo njalo.
Yintoni i-thermal conductivity?
Ukuqhuba kobushushu kubhekisa kwiimeko zokudlulisa ubushushu ezizinzileyo, izinto ezinobukhulu obuyi-1m, umahluko wobushushu kumacala omabini omphezulu yi-1 degree (K,°C), kwiyure e-1, kumgama we-1 square metres yokudlulisa ubushushu, iyunithi yi-watt/meter · degree (W/(m·K), apho i-K inokutshintshwa yi-℃).
Ulawulo lobushushu lunxulumene nolwakhiwo, uxinano, umxholo wokufuma, ubushushu kunye nezinye izinto zezinto. Izinto ezinesakhiwo esingaguqukiyo kunye noxinano oluphantsi zine-conductivity ephantsi yobushushu. Xa umxholo wokufuma kunye nobushushu bezinto ziphantsi, ulungelelwaniso lobushushu luncinci.
Yintoni i-RTV?
I-RTV sisifinyezo segama elithi "Irabha yeSilicone eVulcanized yoBushushu beGumbi" ngesiNgesi, esibizwa ngokuba yi "rubber silicone evulcanized yobushushu begumbi" okanye "irabha yesilicone evuthwe kubushushu begumbi", oko kukuthi, le rabha yesilicone inokunyangeka kwiimeko zobushushu begumbi (izithinteli zokwenziwa ziirabha zesilicone ezivulcanized zobushushu obuphezulu). I-RTV antifouling flashover coating yamkelwa kakhulu ngabasebenzisi benkqubo yamandla ngenxa yesakhono sayo esinamandla sokulwa nokungcola kwe-flashover, inkqubo yokungabi nokugcinwa kunye nenkqubo elula yokugquma, kwaye iphuhliswe ngokukhawuleza.
Yintoni i-UL? Ngawaphi amabakala e-UL?
I-UL imfutshane kwi-Underwriter Laboratories Ins. UL Udidi lokutsha: Ukutsha I-UL94 grade yeyona migangatho yokutsha esetyenziswa kakhulu kwizixhobo zeplastiki. Isetyenziselwa ukuvavanya amandla ezinto zokutsha emva kokuba zitshisiwe. Ngokwesantya sokutsha, ixesha lokutsha, ukumelana nokuthontsiza kunye nokuba ithontsi liyatsha na kunokuba neendlela ezahlukeneyo zokuvavanya. Amaxabiso amaninzi anokufunyanwa kwisixhobo ngasinye esivavanywayo kuxhomekeke kumbala okanye ubukhulu. Xa izinto zemveliso zikhethiwe, i-UL grade yayo kufuneka ihlangabezane nenqanaba lokutsha elithintela ilangatye kwiindawo zeplastiki ukusuka kwi-HB, V-2, V-1 ukuya kwi-V-0: HB: elona nqanaba liphantsi lokutsha elithintela ilangatye kumgangatho we-UL94. Kwiisampuli ezinobukhulu obuyi-3 ukuya kwi-13 mm, izinga lokutsha lingaphantsi kwe-40 mm ngomzuzu; Kwiisampuli ezingaphantsi kwe-3 mm ubukhulu, izinga lokutsha lingaphantsi kwe-70 mm ngomzuzu; Okanye ukucima phambi kophawu lwe-100 mm.
V-2: Emva kovavanyo lokutsha lwemizuzwana eli-10 kwisampulu, ilangatye lingacinywa kwimizuzwana engama-60, kwaye ezinye izinto ezivuthayo zingawa.
V-1: Emva kovavanyo lokutsha lwemizuzwana eli-10 kwisampulu, ilangatye lingacinywa kwimizuzwana engama-60, kwaye akukho zinto zivuthayo ezinokuwa.
V-0: Emva kovavanyo lokutsha lwemizuzwana eli-10 kwisampulu, ilangatye lingacinywa kwimizuzwana engama-30, kwaye akukho zinto zivuthayo ezinokuwa.
Ezi zizinto ezixhaphakileyo malunga nezincamathelisi ezabelwana ngazo yiSiway, iShanghai Siway Building Materials Co., Limited yasekwa ngo-1984, Okwangoku, inesatifikethi senkqubo yomgangatho wehlabathi se-ISO9001:2015 kunye nesatifikethi solawulo lwenkqubo yokusingqongileyo se-ISO14001 kunye nezinye iziqinisekiso.
