Ingaba sifuna ukuphuhlisa i-adhesives okanye ukuthenga i-adhesives, sihlala sibona ukuba ezinye i-adhesives ziya kuba ne-ROHS certification, i-NFS certification, kunye ne-thermal conductivity ye-adhesives, i-thermal conductivity, njl., zimela ntoni ezi? Dibana nabo siway apha ngezantsi!
Yintoni iROHS?
I-ROHS ngumgangatho osisinyanzelo ophuhliswe ngumthetho we-European Union, igama layo elipheleleyo nguMyalelo weUkuthintelwa kwezinto ezinobungozi kwizixhobo zombane kunye nezombane. Umgangatho uya kuphunyezwa ngokusemthethweni ngomhla we-1 kaJulayi, i-2006, ikakhulu isetyenziselwa ukulawula izinto kunye nemigangatho yenkqubo yeemveliso ze-elektroniki kunye nombane, ukwenzela ukuba kusebenze ngakumbi kwimpilo yabantu kunye nokukhuselwa kokusingqongileyo. Injongo yomgangatho kukuphelisa ilothe, i-mercury, i-cadmium, i-hexvalent chromium, i-polybrominated biphenyls kunye ne-polybrominated biphenyl ethers kwiimveliso zemoto kunye ne-elektroniki, kunye nokugxila kumxholo welothe akufanele kudlule i-1%.
Yintoni i-NSF? Yintoni i-FDA? Yintoni umahluko phakathi kwabo?
1. I-NSF sisishunqulelo sesiNgesi seNational Health Foundation yase-United States, engumbutho wesithathu ongenzi nzuzo. Isekelwe kwimigangatho yesizwe yase-United States, ngophuhliso lwemigangatho, uvavanyo kunye nokuqinisekiswa, ulawulo lwesatifikethi kunye namaxwebhu ophicotho, imfundo kunye noqeqesho, uphando kunye nezinye iindlela zokuqinisekisa kunye nokulawula iimveliso kunye nobuchwepheshe obunxulumene nempilo yoluntu kunye nokusingqongileyo. .
2. Ngokumalunga nesiqinisekiso se-NSF, i-National Health Foundation (NSF) ayiyo-arhente karhulumente, kodwa ngumbutho wenkonzo yabucala engenzi nzuzo. Injongo yayo kukuphucula umgangatho wobomi bempilo yoluntu. I-NSF yenziwe ziingcali zempilo yoluntu kunye nococeko, kubandakanywa nee-arhente zikarhulumente, iiyunivesithi, ishishini kunye namaqela abathengi. Umsebenzi wayo ugxile ekumiseleni imigangatho yophuhliso kunye nolawulo kuzo zonke iimveliso ezinempembelelo kucoceko, impilo yoluntu, njl. Bonke abavelisi abathatha inxaxheba ngokuzithandela abaphumelele ukuhlolwa kwe-NSF banokuqhoboshela ileyibhile ye-NSF kwimveliso kunye noncwadi malunga nemveliso ukubonisa ukuqinisekiswa.
I-3, iinkampani eziqinisekisiweyo ze-NSF, oko kukuthi, iinkampani ze-NSF, ezifana nezixhobo zasekhaya, amayeza, ukutya, impilo, imfundo njalo njalo. Imveliso inxulumene nodidi olulinganayo. I-United States Food and Drug Administration (FDA) yenye yee-arhente ezilawulayo ezisekwe ngurhulumente waseUnited States ngaphakathi kweSebe lezeMpilo kunye neeNkonzo zoLuntu (DHHS) kunye neSebe lezeMpilo kaRhulumente (PHS). Umbutho woqinisekiso lwe-NSF ngumbutho wesithathu ongenzi nzuzo wesiqinisekiso sehlabathi, unembali yeminyaka engama-50, ebandakanyeka ikakhulu kwimpilo yoluntu kunye nokhuseleko kunye nemigangatho yezempilo kunye nomsebenzi wokuqinisekisa imveliso yokutya, uninzi lwemigangatho yoshishino ihlonitshwa ngokubanzi kwihlabathi, kwaye eUnited States ithathwa njengomgangatho. Ingumgangatho ogunyazisiweyo weshishini kunesiqinisekiso se-FDA soLawulo lokuTya kunye noLawulo lweziyobisi lwase-US.
Yintoni i-SGS? Yintoni ubudlelwane phakathi kwe-SGS kunye ne-ROHS?
I-SGS sisishunqulelo se-Societe Generale de Surveillance SA, eguqulelwe njenge "General Notary Firm". Yasekwa ngo-1887, ngoku iyeyona nkampani inkulu kunye neyona indala yehlabathi yabucala yeqela lesithathu ebandakanyeka kumgangatho wemveliso kunye novavanyo lobugcisa. Ikomkhulu eliseGeneva, inamasebe angama-251 kwihlabathi jikelele. I-ROHS ngumyalelo we-EU, i-SGS inokwenza uvavanyo lwesatifikethi semveliso kunye nesatifikethi senkqubo ngokoMyalelo we-ROHS. Kodwa eneneni, ayisiyiyo kuphela ingxelo ye-SGS eyaziwayo, kukho ezinye ii-arhente zovavanyo lomntu wesithathu, njenge-ITS njalo njalo.
Yintoni i-thermal conductivity?
I-Thermal conductivity ibhekiselele phantsi kweemeko ezizinzileyo zokudlulisa ubushushu, i-1m yempahla engqindilili, umahluko weqondo lobushushu kumacala omabini omhlaba yi-1 degree (K, °C), kwiyure enye, kwindawo ye-1 square metres yokudluliselwa kobushushu, iyunithi. yi watt/imitha · isidanga (W/(m·K), apho u-K unokutshintshwa ngu-℃).
I-Thermal conductivity ihambelana nesakhiwo sokubunjwa, ubuninzi, umxholo womswakama, ukushisa kunye nezinye izinto eziphathekayo. Izinto eziphathekayo ezinesakhiwo se-amorphous kunye noxinzelelo oluphantsi lune-conductivity ephantsi ye-thermal. Xa umswakama kunye nobushushu bezinto eziphathekayo ziphantsi, i-thermal conductivity incinci.
Yintoni i-RTV?
I-RTV sisishunqulelo se "Irabha yeSilicone eVulcanized yeGumbi" ngesiNgesi, ebizwa ngokuba "yirabha ye-silicone yobushushu begumbi" okanye "irabha ye-silicone yobushushu begumbi", oko kukuthi, le rabha ye-silicone inokunyangwa kwiimeko zobushushu begumbi (i-synthetic insulators ziphezulu. ubushushu berabha abicah ovulcanized). I-RTV antifouling flashover coating yamkelwe ngokubanzi ngabasebenzisi benkqubo yamandla ngenxa yesakhono sayo esomeleleyo sokuchasa i-flashover, ukugcinwa okungahlawulelwayo kunye nenkqubo elula yokugquma, kwaye iye yaphuhliswa ngokukhawuleza.
Yintoni i-UL? Ngawaphi amabakala anawo u-UL?
I-UL imfutshane kwi-Underwriter Laboratories Ins. IBanga lokutsha le-UL: Ukutsha Umgangatho we-UL94 ngowona mgangatho wokutsha osetyenziswa kakhulu kwizinto zeplastiki. Isetyenziselwa ukuvavanya amandla esixhobo sokufa emva kokutshiswa. Ngokwesantya esivuthayo, ixesha elivuthayo, ukuxhathisa i-drip kunye nokuba ithontsi liyatshisa ingaba neendlela ezahlukeneyo zokuvavanya. Amanani amaninzi anokufunyanwa kwisixhobo ngasinye phantsi kovavanyo ngokuxhomekeke kumbala okanye ubukhulu. Xa imveliso yemveliso ikhethiwe, ibakala layo le-UL kufuneka lihlangabezane nenqanaba lokubuyiswa komlilo leenxalenye zeplastiki ukusuka kwi-HB, V-2,V-1 ukuya kwi-V-0: HB: ibakala eliphantsi le-flame retardant kumgangatho we-UL94. Kwiisampuli ze-3 ukuya kwi-13 mm ubukhulu, izinga lokutsha lingaphantsi kwama-40 mm ngomzuzu; Kwiisampuli ezingaphantsi kwe-3 mm ubukhulu, izinga lokutshisa lingaphantsi kwama-70 mm ngomzuzu; Okanye ukucima phambi kophawu lwe-100 mm.
I-V-2: Emva kweemvavanyo ezimbini zokutsha ze-10-yesibini kwisampuli, ilangatye lingacinywa kwimizuzwana ye-60, kwaye ezinye izinto ezinokutsha zingawa.
I-V-1: Emva kweemvavanyo ezimbini zokutsha ze-10-yesibini kwisampuli, ilangatye lingacinywa kwimizuzwana ye-60, kwaye akukho zixhobo ezinokutsha ezinokuwa.
I-V-0: Emva kweemvavanyo ezimbini zokutsha ze-10-yesibini kwisampuli, ilangatye lingacinywa kwimizuzwana ye-30, kwaye akukho zixhobo ezinokutsha ezinokuwa.
La ngamanqaku olwazi oluqhelekileyo malunga nokunamathelisa okwabelwana ngawo yi-siway, i-Shanghai Siway Building Materials Co., i-Limited isekelwe kwi-1984, Okwangoku, ine-ISO9001: i-2015 isiqinisekiso senkqubo yomgangatho wehlabathi kunye ne-ISO14001 yolawulo lwenkqubo yendalo kunye nezinye iziqinisekiso.
