Kungakhathaliseki ukuthi sifuna ukuthuthukisa ama-adhesives noma ukuthenga izinto zokunamathisela, sivame ukubona ukuthi ezinye izinto zokunamathisela zizoba nesitifiketi se-ROHS, isitifiketi se-NFS, kanye nokuhamba okushisayo kwe-adhesives, ukuqhutshwa kwe-thermal, njll., yini lokhu okumelela? Hlangana nabo ngezansi!
Iyini i-ROHS?
I-ROHS iyindinganiso eyisibopho eyakhiwe umthetho we-European Union, igama layo eligcwele liyiSiqondiso kuUkukhawulelwa Kwezinto Eziyingozi kumishini kagesi nekagesi. Izinga lizosetshenziswa ngokusemthethweni ngoJulayi 1, 2006, ikakhulukazi elisetshenziselwa ukulawula izinto kanye nezinqubo zezindinganiso zemikhiqizo ye-elekthronikhi kanye nekagesi, ukuze ilungele impilo yabantu kanye nokuvikelwa kwemvelo. Inhloso yaleli zinga ukuqeda umthofu, i-mercury, i-cadmium, i-hexvalent chromium, ama-biphenyl ane-polybrominated nama-biphenyl ether e-polybrominated emikhiqizweni yezimoto neyogesi, futhi kugxilwe kokuqukethwe komthofu akufanele kudlule u-1%.
Yini i-NSF? Yini i-FDA? Uyini umehluko phakathi kwabo?
1. I-NSF isifinyezo sesiNgisi se-National Health Foundation yase-United States, okuyinhlangano yezinkampani zangaphandle engenzi nzuzo. Kusekelwe ezimisweni kazwelonke zase-United States, ngokuthuthukiswa kwamazinga, ukuhlola nokuqinisekisa, ukuphathwa kwezitifiketi kanye nemibhalo yocwaningomabhuku, imfundo nokuqeqeshwa, ucwaningo nezinye izindlela zokuqinisekisa nokwengamela imikhiqizo nobuchwepheshe obuhlobene nempilo yomphakathi kanye nemvelo. .
2. Mayelana nesitifiketi se-NSF, i-National Health Foundation (NSF) ayiyona i-ejensi kahulumeni, kodwa inhlangano yezinkonzo ezizimele engenzi nzuzo. Inhloso yawo ukwenza ngcono izinga lempilo yezempilo yomphakathi. I-NSF yakhiwe ngochwepheshe bezempilo yomphakathi kanye nenhlanzeko, okuhlanganisa izinhlangano zikahulumeni, amanyuvesi, izimboni kanye namaqembu abathengi. Umsebenzi wayo ugxile ekubekeni izindinganiso zokuthuthukiswa kanye nokuphatha kuyo yonke imikhiqizo enomthelela kwenhlanzeko, impilo yomphakathi, njll. I-NSF inelabhorethri ebanzi ehlola yonke imikhiqizo ehlolelwe ukuhambisana nezindinganiso zokuhlola. Bonke abakhiqizi ababamba iqhaza ngokuzithandela abaphumelele ukuhlolwa kwe-NSF banganamathisela ilebula ye-NSF emkhiqizweni kanye nemibhalo emayelana nomkhiqizo ukukhombisa isiqiniseko.
3, izinkampani eziqinisekisiwe ze-NSF, okungukuthi, izinkampani ze-NSF, ezifana nempahla yasendlini, imithi, ukudla, ezempilo, imfundo nokunye. Umkhiqizo uhlobene nesigaba esilinganayo. I-United States Food and Drug Administration (FDA) ingesinye sezikhungo eziphezulu ezisungulwe uhulumeni wase-United States ngaphakathi koMnyango Wezempilo Nezinsizakalo Zabantu (DHHS) kanye Nomnyango Wezempilo Yomphakathi (PHS). Inhlangano yezitifiketi ze-NSF iyinhlangano engenzi nzuzo yokuqinisekisa izitifiketi zomhlaba wonke ezivela eceleni, inomlando weminyaka engama-50, ibambe iqhaza kakhulu kumazinga ezempilo yomphakathi kanye nokuphepha kanye nezempilo kanye nomsebenzi wokunikeza isitifiketi somkhiqizo wokudla, izindinganiso zayo eziningi zemboni zihlonishwa kakhulu emhlabeni, futhi e-United States kuthathwa njengokujwayelekile. Kuyindinganiso yomkhakha egunyazwe kakhulu kunesitifiketi se-FDA se-US Food and Drug Administration.
Yini i-SGS? Buyini ubudlelwano phakathi kwe-SGS ne-ROHS?
I-SGS isifinyezo se-Societe Generale de Surveillance SA, esihunyushwe ngokuthi "General Notary Firm". Yasungulwa ngo-1887, njengamanje iyinkampani ezimele enkulu kunazo zonke emhlabeni futhi endala kunazo zonke emhlabeni wonke ezibandakanya ikhwalithi yomkhiqizo kanye nokuhlolwa kobuchwepheshe.Ikomkhulu e-Geneva, inamagatsha angama-251 emhlabeni jikelele. I-ROHS iyisiyalelo se-EU, i-SGS ingenza ukuhlolwa komkhiqizo kanye nesitifiketi sohlelo ngokuya nge-ROHS Directive. Kodwa empeleni, akuwona kuphela umbiko we-SGS owaziwayo, akhona amanye ama-ejensi okuhlola ezinkampani zangaphandle, njenge-ITS nokunye.
Yiziphi conductivity ezishisayo?
I-Thermal conductivity ibhekisela ngaphansi kwezimo ezizinzile zokudlulisa ukushisa, impahla engu-1m obukhulu, umehluko wezinga lokushisa ezinhlangothini zombili zomhlaba yi-1 degree (K, °C), ngehora elingu-1, endaweni eyi-1 square metres yokudlulisa ukushisa, iyunithi. i-watt/imitha · degree (W/(m·K), lapho u-K engashintshwa ngo-℃).
I-Thermal conductivity ihlobene nesakhiwo sokubunjwa, ukuminyana, okuqukethwe komswakama, izinga lokushisa nezinye izici zezinto ezibonakalayo. Izinto ezinesakhiwo se-amorphous kanye ne-low density zine-conductivity ephansi yokushisa. Lapho umswakama kanye nokushisa kwempahla kuphansi, ukuqhutshwa kwe-thermal kuncane.
Iyini i-RTV?
I-RTV isifinyezo se-"Room Temperature Vulcanized Silicone Rubber" ngesiNgisi, esibizwa ngokuthi "irabha ye-silicone yegumbi lokushisa elivundisiwe" noma "irabha ye-silicone yerabha ephulukisiwe", okungukuthi, le rabha ye-silicone ingelapheka ezimweni zokushisa zekamelo (izivikeli zokwenziwa ziphezulu. Irabha ye-silicone ye-vulcanized vulcanized). I-RTV antifouling flashover coating yamukelwe kabanzi ngabasebenzisi besistimu yamandla ngenxa yekhono layo eliqinile le-flashover yokulwa nokungcola, inqubo yokunakekela engagcini futhi elula yokuhlanganisa, futhi ithuthukiswe ngokushesha.
Yini i-UL? I-UL inamaphi amamaki?
I-UL imfushane yokuthi i-Underwriter Laboratories Ins. I-UL Combustion Grade: Ukuvutha Ibanga le-UL94 liyindinganiso esetshenziswa kakhulu yokuvutha kwezinto zepulasitiki. Isetshenziselwa ukuhlola ikhono lempahla yokufa ngemva kokushiswa. Ngokusho kwejubane elivuthayo, isikhathi esivuthayo, ukumelana nokuvuza nokuthi ngabe ukudonsa kuyavutha kungaba nezindlela ezihlukahlukene zokuhlola. Amanani amaningi angatholwa kunto ngayinye ehlolwayo kuye ngombala noma ukujiya. Uma impahla yomkhiqizo ikhethiwe, ibanga layo le-UL kufanele lihlangabezane nebanga elibushelelezi ilangabi lezingxenye zepulasitiki ukusuka ku-HB, V-2,V-1 ukuya ku-V-0: HB: ibanga eliphansi kakhulu le-flame retardant kuzinga le-UL94. Kumasampuli 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 cisha phambi kophawu lwe-100 mm.
I-V-2: Ngemva kokuhlolwa kokuvutha kwemizuzwana eyi-10 kusampula, ilangabi lingacisha kumasekhondi angu-60, futhi ezinye izinto ezivuthayo zingawa.
I-V-1: Ngemva kokuhlolwa kokuvutha kwemizuzwana eyi-10 kusampula, ilangabi lingacisha kumasekhondi angu-60, futhi azikho izinto ezivuthayo ezingawa.
I-V-0: Ngemva kokuhlolwa kokuvutha kwemizuzwana eyi-10 kusampula, ilangabi lingacisha kumasekhondi angu-30, futhi azikho izinto ezivuthayo ezingawa.
Lawa amaphuzu olwazi olujwayelekile mayelana nezinamatheliso ezabiwe yi-siway, i-Shanghai Siway Building Materials Co., Limited yasungulwa ngo-1984, Njengamanje, ine-ISO9001: isitifiketi sohlelo lwekhwalithi yamazwe ngamazwe ka-2015 kanye nesitifiketi sokuphathwa kwesistimu yezemvelo ye-ISO14001 nezinye izitifiketi.
