Twaba dushaka guteza imbere ibifatika cyangwa kugura ibifatika, mubisanzwe tubona ko ibifatika bimwe bizaba bifite icyemezo cya ROHS, icyemezo cya NFS, hamwe nubushyuhe bwumuriro bwibikoresho, ubushyuhe bwumuriro, nibindi, ibi byerekana iki? Basange hamwe na siway hepfo!
ROHS ni iki?
ROHS ni itegeko riteganijwe gutegurwa n’amategeko y’ubumwe bw’ibihugu by’Uburayi, izina ryayo ryuzuye ni Amabwiriza kuriKubuza ibintu bishobora guteza akaga ibikoresho bya elegitoroniki n'amashanyarazi. Ibipimo bizashyirwa mu bikorwa ku mugaragaro ku ya 1 Nyakanga 2006, ahanini bikoreshwa mu kugenzura ibipimo ngenderwaho n’ibikorwa by’ibikoresho bya elegitoroniki n’amashanyarazi, ku buryo byorohereza ubuzima bw’abantu no kurengera ibidukikije. Intego yibipimo ni ugukuraho isasu, mercure, kadmium, chromium ya hexvalent, biphenili polybromine na polybromine biphenyl ethers mu bicuruzwa bya moteri na elegitoronike, kandi kwibanda ku bikubiye mu isasu ntibigomba kurenga 1%.
NSF ni iki? FDA ni iki? Ni irihe tandukaniro riri hagati yabo?
1. NSF ni impfunyapfunyo y'Icyongereza ya National Health Foundation yo muri Amerika, akaba ari umuryango udaharanira inyungu. Ishingiye ku bipimo ngenderwaho by’igihugu cya Leta zunze ubumwe z’Amerika, binyuze mu guteza imbere ibipimo, gupima no kugenzura, gucunga ibyemezo n’inyandiko zubugenzuzi, uburezi n’amahugurwa, ubushakashatsi n’ubundi buryo bwo kureba no kugenzura ibicuruzwa n’ikoranabuhanga bijyanye n’ubuzima rusange n’ibidukikije; .
2. Kubijyanye nicyemezo cya NSF, Fondasiyo yigihugu yubuzima (NSF) ntabwo ari ikigo cya leta, ahubwo ni umuryango wigenga udaharanira inyungu. Intego yacyo ni ukuzamura imibereho yubuzima rusange. NSF igizwe ninzobere mu buzima n’isuku, harimo ibigo bya leta, kaminuza, inganda n’amatsinda y’abaguzi. Igikorwa cyacyo cyibanda ku gushyiraho amahame n’imicungire y’ibicuruzwa byose bigira ingaruka ku isuku, ubuzima rusange, n’ibindi. NSF ifite laboratoire yuzuye igerageza ibicuruzwa byose byapimwe kugirango byubahirize ibipimo byubugenzuzi. Abakora ibicuruzwa bose bitabiriye kubushake batsinze ubugenzuzi bwa NSF barashobora kugerekaho ikirango cya NSF kubicuruzwa nibitabo byerekeranye nibicuruzwa kugirango berekane ibyiringiro.
3, Ibigo byemewe na NSF, ni ukuvuga ibigo bya NSF, nk'ibikoresho byo mu rugo, ubuvuzi, ibiryo, ubuzima, uburezi n'ibindi. Ibicuruzwa bifitanye isano nicyiciro gihwanye. Ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) ni kimwe mu bigo nyobozi byashyizweho na guverinoma y’Amerika mu ishami ry’ubuzima n’ibikorwa bya muntu (DHHS) n’ishami ry’ubuzima rusange (PHS). Urwego rwemeza ibyemezo bya NSF ni umuryango udaharanira inyungu w’umuryango wa gatatu w’impamyabumenyi mpuzamahanga, ufite amateka y’imyaka 50, cyane cyane ukora ibikorwa by’ubuzima rusange n’umutekano n’ubuziranenge bw’ubuzima ndetse n’ibikorwa byo kwemeza ibicuruzwa, ibyinshi mu bipimo by’inganda byubahwa cyane ku isi, kandi muri Amerika bifatwa nkibisanzwe. Nibikorwa byemewe byinganda kuruta icyemezo cya FDA cyubuyobozi bushinzwe ibiryo n'ibiyobyabwenge muri Amerika.
SGS ni iki? Ni irihe sano riri hagati ya SGS na ROHS?
SGS ni impfunyapfunyo ya Societe Generale de Surveillance SA, bisobanurwa ngo "Noteri Firime". Yashinzwe mu 1887, kuri ubu ni isosiyete nini ku isi kandi ishaje cyane y’abikorera ku giti cyabo mu masosiyete mpuzamahanga y’ibihugu byinshi ikora ubuziranenge bw’ibicuruzwa n’isuzuma rya tekiniki. Iherereye i Geneve, ifite amashami 251 ku isi. ROHS nubuyobozi bwa EU, SGS irashobora gukora ibizamini byibicuruzwa no kwemeza sisitemu ukurikije amabwiriza ya ROHS. Ariko mubyukuri, ntabwo raporo ya SGS yonyine izwi, hariho izindi nzego zindi zipima, nka ITS nibindi.
Ubushyuhe bwumuriro ni ubuhe?
Ubushyuhe bwumuriro bivuga mubihe byimiterere yubushyuhe butajegajega, ibintu 1m byimbitse, itandukaniro ryubushyuhe kumpande zombi zubuso ni dogere 1 (K, ° C), mumasaha 1, unyuze mubuso bwa metero kare 1 yo kohereza ubushyuhe, igice ni watt / metero · dogere (W / (m · K), aho K ishobora gusimburwa na ℃).
Ubushyuhe bwumuriro bujyanye nuburyo bugizwe, ubwinshi, ibirimo ubuhehere, ubushyuhe nibindi bintu byibikoresho. Ibikoresho bifite imiterere ya amorphous nubucucike buke bifite ubushyuhe buke bwumuriro. Iyo ubuhehere nubushyuhe bwibikoresho biri hasi, ubushyuhe bwumuriro ni buto.
RTV ni iki?
RTV ni impfunyapfunyo ya "Icyumba cy'ubushyuhe bwa Vulcanized Silicone Rubber" mu Cyongereza, cyitwa "icyumba cy'ubushyuhe bwo mu cyumba cyitwa silicone rubber" cyangwa "ubushyuhe bwo mu cyumba bwakize silicone reberi", ni ukuvuga ko iyi reberi ya silicone ishobora gukira mu gihe cy'ubushyuhe bw'icyumba (insulator zikora neza ni nyinshi) ubushyuhe bwa volcanized silicone rubber). RTV irwanya antifouling flashover yakiriwe neza nabakoresha sisitemu yububasha kubera imbaraga zayo zikomeye zo kurwanya flashover, kubungabunga ibidukikije kandi byoroshye, kandi byatejwe imbere byihuse.
UL ni iki? Ni ibihe byiciro UL ifite?
UL ni ngufi kuri Laboratoire Yandika Ins. Icyiciro cya UL Gutwika Icyiciro: Flammability Icyiciro cya UL94 nicyo gikoreshwa cyane mu gutwika ibikoresho bya plastiki. Byakoreshejwe mugusuzuma ubushobozi bwibikoresho byo gupfa nyuma yo gutwikwa. Ukurikije umuvuduko wo gutwika, igihe cyo gutwika, kurwanya ibitonyanga no kumenya niba igitonyanga cyaka bishobora kugira uburyo butandukanye bwo gusuzuma. Indangagaciro nyinshi zirashobora kuboneka kuri buri kintu kiri munsi yikizamini bitewe nibara cyangwa ubunini. Iyo ibikoresho byibicuruzwa byatoranijwe, urwego rwa UL rugomba kuba rwujuje icyiciro cya flame retardant yibice bya plastike kuva HB, V-2, V-1 kugeza V-0: HB: icyiciro cyo hasi cya flame retardant murwego rwa UL94. Kuburugero rwa mm 3 kugeza kuri 13 z'ubugari, igipimo cyo gutwikwa kiri munsi ya mm 40 kumunota; Kuburugero ruri munsi ya mm 3 z'ubugari, igipimo cyo gutwika kiri munsi ya 70 mm kumunota; Cyangwa kuzimya imbere yikimenyetso cya mm 100.
V-2: Nyuma yikizamini cya kabiri cyamasegonda 10 kumasegonda, urumuri rushobora kuzimya mumasegonda 60, kandi umuriro ushobora kugwa.
V-1: Nyuma yikizamini cya kabiri cyamasegonda 10 kumasegonda, urumuri rushobora kuzimwa mumasegonda 60, kandi ntamuriro ushobora kugwa.
V-0: Nyuma yikizamini cya kabiri cyamasegonda 10 kumasegonda, urumuri rushobora kuzimya mumasegonda 30, kandi ntamuriro ushobora kugwa.
Izi nizo ngingo zisanzwe zerekeye ibijyanye n’ibiti bisangiwe na siway, Shanghai Siway Building Materials Co., Limited yashinzwe mu 1984, Kugeza ubu, ifite impamyabumenyi mpuzamahanga ya ISO9001: 2015 hamwe n’icyemezo cyo gucunga ibidukikije cya ISO14001 n’ibindi byemezo.
