Kungakhathaliseki ukuthi sifuna ukuthuthukisa izinti noma ukuthenga izinti, sivame ukubona ukuthi ezinye izinti zizoba nesitifiketi se-ROHS, isitifiketi se-NFS, kanye nokuqhuba ukushisa kwezinti, ukuqhuba ukushisa, njll., lokhu kumelelani? Hlangana nazo nge-siway ngezansi!
Iyini i-ROHS?
I-ROHS iyindinganiso ephoqelekile ethuthukiswe ngumthetho we-European Union, igama layo eliphelele yi-Directive on theUkuvinjelwa Kwezinto Eziyingozi Emishinini Kagesi Nasezimotweni. Le nqubo izoqala ukusebenza ngokusemthethweni mhla lu-1 kuNtulikazi 2006, ikakhulukazi esetshenziselwa ukulawula izindinganiso zezinto zokwakha kanye nezinqubo zemikhiqizo kagesi neye-elekthronikhi, ukuze ibe ngcono kakhulu empilweni yabantu kanye nokuvikelwa kwemvelo. Inhloso yale nqubo ukususa i-lead, i-mercury, i-cadmium, i-hexvalent chromium, i-polybrominated biphenyls kanye ne-polybrominated biphenyl ethers emikhiqizweni yezimoto neye-elekthronikhi, futhi ukugxila kokuqukethwe kwe-lead akufanele kudlule u-1%.
Iyini i-NSF? Iyini i-FDA? Uyini umehluko phakathi kwabo?
1. I-NSF yisifinyezo sesiNgisi se-National Health Foundation yase-United States, okuyinhlangano engenzi nzuzo yangaphandle. Isekelwe ezindinganisweni zikazwelonke zase-United States, ngokuthuthukiswa kwezindinganiso, ukuhlolwa nokuqinisekiswa, ukuphathwa kwezitifiketi kanye nemibhalo yokuhlola, imfundo nokuqeqeshwa, ucwaningo kanye nezinye izindlela zokuqinisekisa nokuphatha imikhiqizo kanye nobuchwepheshe obuhlobene nempilo yomphakathi kanye nemvelo.
2. Ngokuphathelene nesitifiketi se-NSF, i-National Health Foundation (NSF) akuyona inhlangano kahulumeni, kodwa inhlangano yezinsizakalo ezizimele engenzi nzuzo. Inhloso yayo ukuthuthukisa ikhwalithi yokuphila kwempilo yomphakathi. I-NSF yakhiwe ochwepheshe bezempilo yomphakathi kanye nokuhlanzeka, okuhlanganisa izinhlangano zikahulumeni, amanyuvesi, imboni kanye namaqembu abathengi. Umsebenzi wayo ugxile ekubekeni amazinga okuthuthukiswa nokuphathwa kwayo yonke imikhiqizo enomthelela ekuhlanzekeni, empilweni yomphakathi, njll. I-NSF inelabhorethri ephelele ehlola yonke imikhiqizo ehlolwe ukuthi iyahambisana yini nezindinganiso zokuhlola. Bonke abakhiqizi abahlanganyela ngokuzithandela abadlula ekuhlolweni kwe-NSF banganamathisela ilebula le-NSF kumkhiqizo kanye nezincwadi mayelana nomkhiqizo ukuze babonise isiqinisekiso.
3, izinkampani eziqinisekiswe yi-NSF, okungukuthi, izinkampani ze-NSF, njengezinto zasekhaya, imithi, ukudla, impilo, imfundo njalo njalo. Lo mkhiqizo uhlobene nesigaba esifanayo. I-United States Food and Drug Administration (FDA) ingenye yezikhungo eziphezulu ezisungulwe uhulumeni wase-United States ngaphakathi koMnyango Wezempilo Nezinsizakalo Zabantu (DHHS) kanye noMnyango Wezempilo Yomphakathi (PHS). Inhlangano yezitifiketi ze-NSF iyinhlangano yezitifiketi yamazwe ngamazwe engenzi nzuzo, inomlando weminyaka engama-50, ehileleke kakhulu ezindinganisweni zempilo yomphakathi kanye nokuphepha kanye nomsebenzi wokuqinisekiswa komkhiqizo wokudla, amazinga ayo amaningi embonini ahlonishwa kakhulu emhlabeni, futhi e-United States ibhekwa njengendinganiso. Kuyindinganiso yezimboni enegunya kakhulu kunesitifiketi se-FDA se-US Food and Drug Administration.
Iyini i-SGS? Buyini ubudlelwano phakathi kwe-SGS ne-ROHS?
I-SGS yisifinyezo se-Societe Generale de Surveillance SA, esihunyushwa ngokuthi "i-General Notary Firm". Yasungulwa ngo-1887, okwamanje iyinkampani enkulu kunazo zonke futhi endala kunazo zonke emhlabeni ezimele yangaphandle ehileleke kwikhwalithi yomkhiqizo kanye nokuhlolwa kobuchwepheshe. Inehhovisi layo elikhulu eGeneva, inamagatsha angu-251 emhlabeni jikelele. I-ROHS iyisiqondiso se-EU, i-SGS ingenza ukuhlolwa kokuqinisekiswa komkhiqizo kanye nokuqinisekiswa kohlelo ngokusho kwe-ROHS Directive. Kodwa empeleni, akuwona umbiko we-SGS kuphela oqashelwa, kunezinye izikhungo zokuhlola ezivela eceleni, njenge-ITS njalo njalo.
Kuyini ukuhanjiswa kwe-thermal?
Ukushisa okushisayo kubhekisela ngaphansi kwezimo zokudlulisa ukushisa ezizinzile, izinto eziwugqinsi oluyi-1m, umehluko wokushisa ezinhlangothini zombili zobuso yi-1 degree (K,°C), ngehora eli-1, endaweni engamamitha-skwele angu-1 okudlulisa ukushisa, iyunithi iyi-watt/meter · degree (W/(m·K), lapho i-K ingashintshwa khona yi-℃).
Ukuqhuba kwe-thermal kuhlobene nesakhiwo sokwakheka, ubuningi, okuqukethwe umswakama, izinga lokushisa kanye nezinye izinto zezinto. Izinto ezinesakhiwo esingaguquki kanye nobuningi obuphansi zine-thermal conductivity ephansi. Uma okuqukethwe umswakama kanye nezinga lokushisa kwezinto kuphansi, ukuqhubela kwe-thermal kuncane.
Kuyini i-RTV?
I-RTV isifinyezo se-"Room Temperature Vulcanized Silicone Rubber" ngesiNgisi, esibizwa ngokuthi "i-room temperature vulcanized silicone rubber" noma "i-room temperature cured silicone rubber", okungukuthi, le silicone rubber ingelapheka ezimweni zokushisa kwegumbi (izivikelo zokwenziwa ziyi-high temperature vulcanized silicone rubber). I-RTV antifouling flashover coating yamukelwe kabanzi ngabasebenzisi besistimu yamandla ngenxa yekhono layo eliqinile lokulwa nokungcola kwe-flashover, inqubo yokulungisa nokugqoka elula, futhi ithuthukiswe ngokushesha.
Iyini i-UL? Yimaphi amamaki i-UL enawo?
I-UL ifushaniswa ne-Underwriter Laboratories Ins. I-UL Combustion Grade: Ukuvutha Ibanga le-UL94 liyindinganiso yokuvutha esetshenziswa kakhulu ezintweni zepulasitiki. Lisetshenziselwa ukuhlola ikhono lento yokufa ngemva kokushiswa. Ngokwejubane lokusha, isikhathi sokusha, ukumelana nokuconsa kanye nokuthi ukuwa kuyasha yini kungaba nezindlela ezahlukene zokuhlola. Amanani amaningi angatholakala ngento ngayinye evivinywayo kuye ngombala noma ukujiya. Lapho izinto zomkhiqizo zikhethiwe, izinga layo le-UL kufanele lihlangabezane nezinga lokucisha umlilo lezingxenye zepulasitiki kusukela ku-HB, V-2, V-1 kuya ku-V-0: HB: izinga eliphansi kakhulu lokucisha umlilo ezingeni le-UL94. Kumasampula angu-3 kuya ku-13 mm ubukhulu, izinga lokusha lingaphansi kuka-40 mm ngomzuzu; Kumasampula angaphansi kuka-3 mm ubukhulu, izinga lokusha lingaphansi kuka-70 mm ngomzuzu; Noma ukucima phambi kophawu lwe-100 mm.
V-2: Ngemva kokuhlolwa kokusha kwemizuzwana eyi-10 kusampula, ilangabi lingacinywa ngemizuzwana engama-60, futhi ezinye izinto ezivuthayo zingawa.
V-1: Ngemva kokuhlolwa kokusha kwemizuzwana eyi-10 kusampula, ilangabi lingacinywa ngemizuzwana engama-60, futhi akukho zinto ezivuthayo ezingawa.
V-0: Ngemva kokuhlolwa kokusha kwemizuzwana eyi-10 kusampula, ilangabi lingacinywa ngemizuzwana engama-30, futhi akukho zinto ezivuthayo ezingawa.
Lawa amaphuzu olwazi oluvamile mayelana nezinamathelisi ezabiwe yi-siway, i-Shanghai Siway Building Materials Co., Limited yasungulwa ngo-1984, Njengamanje, inesitifiketi se-ISO9001:2015 sekhwalithi yomhlaba wonke kanye nesitifiketi sokuphathwa kwesistimu yezemvelo se-ISO14001 kanye nezinye izitifiketi.
