Chii chinonzi ROHS?
ROHS chiyero chinosungirwa chakagadzirwa neEuropean Union mutemo, zita rayo rakazara ndiro Directive paKudzorwa kweHazardous Substances mumagetsi nemagetsi midziyo. Iyo chiyero ichaitwa zviri pamutemo muna Chikunguru 1, 2006, inonyanya kushandiswa kudzora zvinhu uye kugadzirisa zviyero zvemagetsi nemagetsi zvigadzirwa, kuitira kuti zvive zvakanyanya kubatsira kune hutano hwevanhu uye kuchengetedzwa kwezvakatipoteredza. Chinangwa chechiyero ndechekubvisa lead, mercury, cadmium, hexvalent chromium, polybrominated biphenyls uye polybrominated biphenyl ethers mumotokari uye zvigadzirwa zvemagetsi, uye kutarisa pane zviri mutobvu hazvifanirwe kudarika 1%.
Chii chinonzi NSF? Chii chinonzi FDA? Ndeupi musiyano pakati pavo?
1. NSF ndicho chidimburidzo cheChirungu cheNational Health Foundation yekuUnited States, inova sangano rechitatu risingabatsiri. Izvo zvakavakirwa pamiyero yenyika yeUnited States, kuburikidza nekuvandudzwa kwemazinga, kuyedzwa uye kusimbiswa, manejimendi ezvitupa uye zvinyorwa zvekuongorora, dzidzo nekudzidziswa, tsvakiridzo uye dzimwe nzira dzekuona uye kutarisa zvigadzirwa uye matekinoroji ane chekuita nehutano hweveruzhinji uye nharaunda. .
2. Panyaya yekupihwa chitupa cheNSF, National Health Foundation (NSF) harisi sangano rehurumende, asi isangano rebasa rakazvimirira. Chinangwa chayo ndechekuvandudza mararamiro ehutano hweveruzhinji. NSF inoumbwa nenyanzvi dzehutano uye hutsanana, kusanganisira masangano ehurumende, mayunivhesiti, maindasitiri nemapoka evatengi. Basa rayo rinotarisa kumisa budiriro uye manejimendi ekutarisira zvigadzirwa zvese zvine chekuita nehutsanana, hutano hweveruzhinji, nezvimwewo. NSF ine rabhoritari yakazara inoedza zvese zvigadzirwa zvakaedzwa kuti zvitevedzerwe nekuongorora zviyero. Vese vagadziri vanozvipira vanopasa ongororo yeNSF vanogona kubatanidza iyo NSF label pachigadzirwa uye zvinyorwa nezve chigadzirwa kuratidza vimbiso.
3, NSF certified makambani, kureva, NSF makambani, akadai midziyo yemumba, mishonga, chikafu, hutano, dzidzo nezvimwe zvakadaro. Chigadzirwa chakabatana nechikamu chakaenzana. United States Chikafu neDrug Administration (FDA) nderimwe remasangano makuru akagadzwa nehurumende yeUnited States mukati meDhipatimendi reHutano neHuman Services (DHHS) uye Dhipatimendi rePublic Health (PHS). NSF certification body isangano risingabatsiri rechitatu bato repasirese certification sangano, rine nhoroondo yemakore makumi mashanu, rinonyanya kuita hutano hweveruzhinji nekuchengetedzeka uye hutano zviyero uye basa retifiketi yechigadzirwa chechikafu, mazhinji emaindasitiri ayo anoremekedzwa zvakanyanya munyika, uye muUnited States inoonekwa seyakajairwa. Iyo ine chiremera cheindasitiri chiyero kupfuura iyo FDA certification yeUS Food and Drug Administration.
Chii chinonzi SGS? Chii chiri hukama pakati peSGS neROHS?
SGS ndiyo chidimbu cheSociete Generale de Surveillance SA, yakashandurwa se "General Notary Firm". Yakavambwa muna 1887, parizvino ndiyo kambani hombe pasirese uye yekare yakazvimirira yechitatu-bato renyika dzakawanda iri kuita zvemhando yezvigadzirwa uye kuongororwa kwehunyanzvi.Musoro uri kuGeneva, une mapazi 251 pasi rose. ROHS ndiyo murairo weEU, SGS inogona kuyedza chigadzirwa chitupa uye system certification zvinoenderana neROHS Directive. Asi muchokwadi, kwete chete SGS chirevo chinozivikanwa, kune mamwe echitatu-bato rekuyedza masangano, akadai ITS uye zvichingodaro.
Chii chinonzi thermal conductivity?
Thermal conductivity inoreva pasi pemamiriro akagadzikana ekutamisa kupisa, 1m gobvu zvinhu, mutsauko wetembiricha pamativi ese epamusoro i1 dhigirii (K, ° C), muawa 1, kuburikidza nenzvimbo ye1 square mita yekupisa kupisa, iyo unit. is watt/metres · degree (W/(m·K), apo K inogona kutsiviwa ne℃).
Thermal conductivity inoenderana neyakaumbwa chimiro, density, hunyoro hwemukati, tembiricha uye zvimwe zvinhu zvezvinhu. Zvishandiso zvine amorphous chimiro uye yakaderera density ine yakaderera thermal conductivity. Kana hunyoro hwemukati uye tembiricha yezvinhu zvakaderera, iyo thermal conductivity idiki.
Chii chinonzi RTV?
RTV ndiyo chidimbu che "Room Temperature Vulcanized Silicone Rubber" muChirungu, inonzi "room tembiricha vulcanized silicone rubber" kana "tembiricha yekamuri yakarapwa silicone rabha", kureva kuti, iyi silicone rabha inogona kurapwa patembiricha yekamuri (synthetic insulators yakakwirira. tembiricha vulcanized silicone rabha). RTV antifouling flashover coating yakagamuchirwa zvakanyanya nevashandisi vemagetsi system kune yayo yakasimba ye-anti-fouling flashover kugona, kuchengetedza-yemahara uye yakapusa kurongedza maitiro, uye yakagadziridzwa nekukurumidza.
Chii chinonzi UL? Ndeapi mamakisi ane UL?
UL ipfupi kune Underwriter Laboratories Ins. UL Combustion Giredhi: Kupisa Iyo UL94 giredhi ndiyo inonyanya kushandiswa kupisa mwero wemidziyo yepurasitiki. Inoshandiswa kuongorora kugona kwechinhu kufa mushure mekupiswa. Zvinoenderana nekupisa kumhanya, kupisa nguva, kudonhedza kuramba uye kana kudonha kuri kupisa kunogona kuve nemhando dzakasiyana dzekuongorora nzira. Hunhu hwakawanda hunogona kuwanikwa kune chimwe nechimwe chiri pasi pekuyedzwa zvichienderana neruvara kana ukobvu. Kana zvinhu zvechigadzirwa zvasarudzwa, giredhi rayo reUL rinofanira kusangana negiredhi rinodzoreredza moto rezvikamu zvepurasitiki kubva kuHB, V-2,V-1 kuenda kuV-0: HB: giredhi yakaderera yemurazvo wemoto muUL94 standard. Kune sampuli 3 kusvika 13 mm gobvu, chiyero chekupisa chiri pasi pe40 mm paminiti; Kune sampuli isingasviki 3 mm gobvu, chiyero chekupisa chiri pasi pe70 mm paminiti; Kana kudzima pamberi pechiratidzo che 100 mm.
V-2: Mushure mekuedza kaviri kwegumi-sekondi pamuenzaniso, murazvo unogona kudzima mumasekonzi makumi matanhatu, uye zvimwe zvinopisa zvinogona kudonha.
V-1: Mushure mekuedza kaviri kwegumi-yechipiri pamuenzaniso, murazvo unogona kudzima mumasekonzi makumi matanhatu, uye hapana zvinopisa zvinogona kudonha.
V-0: Mushure mekuedza kaviri kwegumi-sekondi pamuenzaniso, murazvo unogona kudzima mumasekonzi makumi matatu, uye hapana zvinopisa zvinogona kudonha.
Aya ndiwo mapoinzi eruzivo rwakajairika nezve anonamira akagovaniswa neSiway, Shanghai Siway Building Materials Co., Limited yakavambwa muna 1984, Parizvino, ine ISO9001: 2015 yepasirese yemhando system certification uye ISO14001 yemamiriro ekunze system management certification uye zvimwe zvitupa.
