Kaya tikufuna kupanga zomatira kapena kugula zomatira, nthawi zambiri timaona kuti zomatira zina zimakhala ndi satifiketi ya ROHS, satifiketi ya NFS, komanso mphamvu ya kutentha ya zomatira, mphamvu ya kutentha, ndi zina zotero, kodi izi zikuyimira chiyani? Dziwani izi ndi njira pansipa!
Kodi ROHS ndi chiyani?
ROHS ndi muyezo wofunikira womwe wapangidwa ndi malamulo a European Union, dzina lake lonse ndi Directive on theKuletsa Zinthu Zoopsa mu zipangizo zamagetsi ndi zamagetsiMuyezowu udzakhazikitsidwa mwalamulo pa Julayi 1, 2006, womwe umagwiritsidwa ntchito makamaka poyang'anira miyezo ya zinthu zamagetsi ndi zamagetsi, kuti ukhale wothandiza kwambiri pa thanzi la anthu komanso kuteteza chilengedwe. Cholinga cha muyezowu ndikuchotsa lead, mercury, cadmium, hexvalent chromium, polybrominated biphenyls ndi polybrominated biphenyl ethers muzinthu zamagalimoto ndi zamagetsi, ndipo kuyang'ana kwambiri kuchuluka kwa lead sikuyenera kupitirira 1%.
Kodi NSF ndi chiyani? Kodi FDA ndi chiyani? Kodi kusiyana kwake kuli kotani?
1. NSF ndi chidule cha Chingerezi cha National Health Foundation of the United States, chomwe ndi bungwe lopanda phindu lachitatu. Chimachokera ku miyezo ya dziko la United States, kudzera mukupanga miyezo, kuyesa ndi kutsimikizira, kuyang'anira zikalata zowunikira, maphunziro ndi maphunziro, kafukufuku ndi njira zina zowonetsetsa ndikuyang'anira zinthu ndi ukadaulo wokhudzana ndi thanzi la anthu komanso chilengedwe.
2. Ponena za satifiketi ya NSF, National Health Foundation (NSF) si bungwe la boma, koma bungwe lopanda phindu la anthu payekha. Cholinga chake ndikukweza moyo wa anthu onse. NSF imapangidwa ndi akatswiri azaumoyo ndi ukhondo, kuphatikizapo mabungwe aboma, mayunivesite, makampani ndi magulu ogula. Ntchito yake imayang'ana kwambiri pakukhazikitsa miyezo yopangira ndi kuyang'anira zinthu zonse zomwe zimakhudza ukhondo, thanzi la anthu, ndi zina zotero. NSF ili ndi labotale yonse yomwe imayesa zinthu zonse zomwe zayesedwa kuti zitsatire miyezo yowunikira. Opanga onse omwe achita nawo kafukufuku wa NSF akhoza kuyika chizindikiro cha NSF pa chinthucho ndi mabuku okhudza chinthucho kuti awonetse chitsimikizo.
3, makampani ovomerezeka a NSF, ndiko kuti, makampani a NSF, monga zipangizo zapakhomo, mankhwala, chakudya, thanzi, maphunziro ndi zina zotero. Chogulitsachi chikugwirizana ndi gulu lofananalo. United States Food and Drug Administration (FDA) ndi imodzi mwa mabungwe akuluakulu omwe akhazikitsidwa ndi boma la United States mkati mwa Dipatimenti ya Zaumoyo ndi Utumiki wa Anthu (DHHS) ndi Dipatimenti ya Zaumoyo wa Anthu (PHS). Bungwe lovomerezeka la NSF ndi bungwe lopanda phindu lapadziko lonse lapansi lopereka ziphaso, lomwe lili ndi mbiri ya zaka 50, makamaka lochita zinthu zokhudzana ndi thanzi la anthu onse komanso chitetezo ndi thanzi komanso ntchito yopereka ziphaso za zakudya, miyezo yake yambiri yamakampani imalemekezedwa kwambiri padziko lonse lapansi, ndipo ku United States imaonedwa ngati muyezo. Ndi muyezo wovomerezeka kwambiri wamakampani kuposa chiphaso cha FDA cha US Food and Drug Administration.
Kodi SGS ndi chiyani? Kodi pali ubale wotani pakati pa SGS ndi ROHS?
SGS ndi chidule cha Societe Generale de Surveillance SA, chomwe chimamasuliridwa kuti "General Notary Firm". Chinakhazikitsidwa mu 1887, pakadali pano ndi kampani yayikulu komanso yakale kwambiri padziko lonse lapansi yachinsinsi yachitatu yomwe imachita bwino kwambiri pakupanga zinthu komanso kuwunika ukadaulo. Likulu lake lili ku Geneva, ndipo lili ndi nthambi 251 padziko lonse lapansi. ROHS ndi malangizo a EU, SGS imatha kuyesa chitsimikizo cha zinthu ndi chitsimikizo cha makina malinga ndi ROHS Directive. Koma kwenikweni, si lipoti la SGS lokha lomwe limadziwika, palinso mabungwe ena oyesa achitatu, monga ITS ndi zina zotero.
Kodi kutentha kwa mpweya ndi chiyani?
Kutumiza kutentha kumatanthauza kuti kutentha kumayenda bwino, ndipo kumakhala kolimba ngati 1m, kusiyana kwa kutentha mbali zonse ziwiri za pamwamba ndi 1 digiri (K,°C), mu ola limodzi, kudutsa m'dera la 1 sqm ya kutentha, chipangizocho ndi watt/mita · digiri (W/(m·K), pomwe K ikhoza kusinthidwa ndi ℃).
Kuchuluka kwa kutentha kumakhudzana ndi kapangidwe kake, kuchuluka kwa zinthu, kuchuluka kwa chinyezi, kutentha ndi zina zomwe zili mu chipangizocho. Zipangizo zomwe zili ndi kapangidwe kake kopanda mawonekedwe komanso kuchuluka kochepa zimakhala ndi kutentha kochepa. Pamene chinyezi ndi kutentha kwa chipangizocho kuli kochepa, kutentha kumakhala kochepa.
Kodi RTV ndi chiyani?
RTV ndi chidule cha "Room Temperature Vulcanized Silicone Rubber" mu Chingerezi, chomwe chimatchedwa "room temperature vulcanized silicone rubber" kapena "room temperature cured silicone rubber", kutanthauza kuti, silicone rabara iyi imatha kuchiritsidwa kutentha kwa chipinda (zotchingira zopangidwa ndi silicone rabara yotenthetsera kwambiri). RTV antifouling flashover coating yalandiridwa kwambiri ndi ogwiritsa ntchito magetsi chifukwa cha mphamvu zake zolimba zotsutsana ndi fouling flashover, zopanda kukonza komanso njira yosavuta yophikira, ndipo yapangidwa mwachangu.
Kodi UL ndi chiyani? Kodi UL ili ndi magiredi otani?
UL ndi chidule cha Underwriter Laboratories Ins. UL Kuyaka kwa Galimoto: Kuyaka Giredi ya UL94 ndiyo muyezo woyaka kwambiri wa zinthu zapulasitiki. Umagwiritsidwa ntchito poyesa kuthekera kwa chinthu kufa chikayatsidwa. Malinga ndi liwiro loyaka, nthawi yoyaka, kukana kwa madontho a madzi komanso ngati dontho likuyaka kungakhale ndi njira zosiyanasiyana zowunikira. Mitengo yambiri ingapezeke pa chinthu chilichonse chomwe chikuyesedwa kutengera mtundu kapena makulidwe. Zinthu za chinthu zikasankhidwa, giredi yake ya UL iyenera kukwaniritsa giredi yoyaka ya zinthu zapulasitiki kuyambira HB, V-2, V-1 mpaka V-0: HB: giredi yotsika kwambiri yoyaka ya moto mu muyezo wa UL94. Pa zitsanzo za makulidwe a 3 mpaka 13 mm, kuchuluka kwa kuyaka ndi kochepera 40 mm pamphindi; Pa zitsanzo zosakwana 3 mm makulidwe, kuchuluka kwa kuyaka ndi kochepera 70 mm pamphindi; Kapena kuzimitsa patsogolo pa chizindikiro cha 100 mm.
V-2: Pambuyo pa mayeso awiri oyatsa moto a masekondi 10 pa chitsanzocho, lawilo likhoza kuzimitsidwa mu masekondi 60, ndipo zina zoyaka moto zimatha kugwa.
V-1: Pambuyo pa mayeso awiri oyatsa moto a masekondi 10 pa chitsanzocho, lawilo likhoza kuzimitsidwa mu masekondi 60, ndipo palibe zoyatsira moto zomwe zingagwe.
V-0: Pambuyo pa mayeso awiri oyatsa moto a masekondi 10 pa chitsanzocho, lawilo likhoza kuzimitsidwa mu masekondi 30, ndipo palibe zoyatsira moto zomwe zingagwe.
Izi ndi mfundo zomwe anthu ambiri amadziwa zokhudza zomatira zomwe zimagawidwa ndi siway, Shanghai Siway Building Materials Co., Limited idakhazikitsidwa mu 1984, Pakadali pano, ili ndi satifiketi ya ISO9001:2015 yapadziko lonse lapansi komanso satifiketi yoyang'anira kayendetsedwe ka chilengedwe cha ISO14001 ndi ziphaso zina.
