Inā makemake mākou e hoʻomohala i nā adhesives a kūʻai paha i nā mea hoʻopili, ʻike pinepine mākou e loaʻa i kekahi mau adhesives ka hōʻoia ROHS, ka palapala NFS, a me ka conductivity thermal o nā adhesives, thermal conductivity, etc., he aha kēia mau mea? E hālāwai me lākou me ka siway ma lalo!
He aha ka ROHS?
ʻO ka ROHS kahi maʻamau i hoʻomohala ʻia e ke kānāwai o ka European Union, ʻo kona inoa piha ka Directive on theKaohi ʻana i nā mea ʻino i nā mea uila a me nā lako uila. E hoʻokō ʻia ka maʻamau ma Iulai 1, 2006, i hoʻohana nui ʻia no ka hoʻoponopono ʻana i nā ʻano mea a me nā kaʻina hana o nā huahana uila a me ka uila, i ʻoi aku ka maikaʻi o ke olakino kanaka a me ka palekana o ke kaiapuni. ʻO ke kumu o ka maʻamau ka hoʻopau ʻana i ke alakaʻi, mercury, cadmium, hexvalent chromium, polybrominated biphenyls a me polybrominated biphenyl ethers i loko o nā mīkini a me nā huahana uila, a ʻo ka nānā ʻana i ka ʻike o ke alakaʻi ʻaʻole pono ma mua o 1%.
He aha ka NSF? He aha ka FDA? He aha ka ʻokoʻa ma waena o lākou?
1. ʻO ka NSF ka pōkole Pelekania o ka National Health Foundation o ʻAmelika Hui Pū ʻIa, ʻo ia ka hui ʻekolu ʻaʻohe waiwai. Hoʻokumu ʻia ia ma nā kūlana aupuni o ʻAmelika Hui Pū ʻIa, ma o ka hoʻomohala ʻana i nā kūlana, hoʻāʻo a hōʻoia, hoʻokele palapala a me nā palapala loiloi, hoʻonaʻauao a hoʻomaʻamaʻa, noiʻi a me nā ʻano ʻē aʻe e hōʻoia a nānā i nā huahana a me nā ʻenehana e pili ana i ke olakino lehulehu a me ke kaiapuni. .
2. E pili ana i ka palapala hōʻoia NSF, ʻaʻole ʻo ka National Health Foundation (NSF) kahi hui aupuni, akā he hui lawelawe pilikino ʻole. ʻO kāna kumu e hoʻomaikaʻi ai i ka maikaʻi o ke ola o ke olakino lehulehu. Hoʻokumu ʻia ka NSF me nā loea olakino a me ka maʻemaʻe, me nā hui aupuni, nā kulanui, nā ʻoihana a me nā hui mea kūʻai aku. Hoʻokumu kāna hana i ka hoʻonohonoho ʻana i nā kūlana hoʻomohala a me ka hoʻokele ʻana no nā huahana āpau e pili ana i ka hoʻomaʻemaʻe, ke olakino lehulehu, a pēlā aku. Hiki i nā mea hana a pau i komo i ka nānā ʻana i ka NSF ke hoʻopili i ka lepili NSF ma ka huahana a me nā palapala e pili ana i ka huahana e hōʻike i ka hōʻoia.
3, NSF i hōʻoia ʻia nā hui, ʻo ia hoʻi, nā hui NSF, e like me nā mea hana hale, lāʻau lapaʻau, meaʻai, olakino, hoʻonaʻauao a pēlā aku. Pili ka huahana i ka māhele like. ʻO ka United States Food and Drug Administration (FDA) kekahi o nā keʻena hoʻokō i hoʻokumu ʻia e ke aupuni o ʻAmelika Hui Pū ʻIa i loko o ke Keʻena ʻOihana Ola a me nā lawelawe kanaka (DHHS) a me ke Keʻena ʻOihana Ola (PHS). ʻO ke kino hōʻoia NSF he hui hōʻoiaʻiʻo honua ʻekolu ʻaoʻao, he 50 mau makahiki, e hana nui ana i ka olakino olakino a me ka palekana a me nā kūlana olakino a me ka hana hōʻoia huahana meaʻai, mahalo nui ʻia ka nui o kāna mau ʻoihana ma ka honua, a ma ʻAmelika Hui Pū ʻIa ua manaʻo ʻia ʻo ia ka maʻamau. He kūlana ʻoihana ʻoi aku ka mana ma mua o ka hōʻoia FDA o ka US Food and Drug Administration.
He aha ka SGS? He aha ka pilina ma waena o SGS a me ROHS?
ʻO SGS ka pōkole o Societe Generale de Surveillance SA, unuhi ʻia ʻo "General Notary Firm". Hoʻokumu ʻia i ka makahiki 1887, ʻo ia ka honua nui loa a me ka mea kahiko pilikino kolu o ka hui multinational i hana i ka maikaʻi o ka huahana a me ka loiloi ʻenehana. ʻO ROHS ka kuhikuhi EU, hiki iā SGS ke hana i ka hōʻoia ʻana i ka huahana a me ka hōʻoia ʻōnaehana e like me ka ROHS Directive. Akā ʻo ka ʻoiaʻiʻo, ʻaʻole ʻike wale ʻia ka hōʻike SGS, aia kekahi mau keʻena hoʻāʻo ʻekolu ʻaoʻao, e like me ITS a pēlā aku.
He aha ke ano o ka thermal conductivity?
Hōʻike ka hoʻoili wela ma lalo o nā kūlana hoʻololi wela paʻa, 1m mānoanoa mea, ʻo ka ʻokoʻa wela ma nā ʻaoʻao ʻelua o ka ʻili he 1 degere (K, °C), i ka hola 1, ma o kahi o 1 mau mika square o ka hoʻoili wela, ka ʻāpana. he watt/mika · degere (W/(m·K), kahi hiki ke pani ʻia ke K e ℃).
Hoʻopili ʻia ka conductivity thermal i ke ʻano o ka haku mele ʻana, ka nui, ka maʻemaʻe, ka mahana a me nā mea ʻē aʻe o ka mea. ʻO nā mea me ka hoʻolālā amorphous a me ka haʻahaʻa haʻahaʻa he haʻahaʻa haʻahaʻa haʻahaʻa. I ka haʻahaʻa o ka makū a me ka mahana o ka mea, liʻiliʻi ka conductivity thermal.
He aha ka RTV?
ʻO RTV ka pōkole o "Room Temperature Vulcanized Silicone Rubber" ma ka ʻōlelo Pelekania, i kapa ʻia ʻo "room temperature vulcanized silicone rubber" a i ʻole "room temperature cured silicone rubber", ʻo ia hoʻi, hiki ke ho'ōla ʻia kēia silicone rubber ma nā kūlana wela o ka lumi (he kiʻekiʻe nā insulators synthetic. ka wela silikoni vulcanized). RTV antifouling flashover coating ua hoʻokipa nui ʻia e nā mea hoʻohana ʻōnaehana mana no kona ikaika anti-fouling flashover hiki, mālama ʻole a maʻalahi ke kaʻina hana, a ua hoʻomohala wikiwiki ʻia.
He aha ka UL? He aha nā māka i loaʻa iā UL?
He pōkole ka UL no Underwriter Laboratories Ins. UL Combustion Grade: Flammability ʻO ka UL94 grade ka mea i hoʻohana nui ʻia ka maʻamau flammability no nā mea plastic. Hoʻohana ʻia ia e loiloi i ka hiki ke make o kahi mea ma hope o ka hoʻā ʻia ʻana. E like me ka wikiwiki o ka puhi ʻana, ka manawa wela, ke kūpaʻa ʻana a inā paha e ʻā ana ka hāʻule hiki ke loaʻa i nā ʻano loiloi like ʻole. Hiki ke loaʻa nā waiwai he nui no kēlā me kēia mea ma lalo o ka hoʻāʻo ʻana ma muli o ke kala a i ʻole ka mānoanoa. Ke koho ʻia ka mea o ka huahana, pono kona māka UL e kūpono i ka pae ʻana o ka lapalapa ahi o nā ʻāpana plastik mai HB, V-2, V-1 a i V-0: HB: ka papa haʻahaʻa haʻahaʻa haʻahaʻa ma ka maʻamau UL94. No nā laʻana 3 a 13 mm mānoanoa, ʻoi aku ka liʻiliʻi o ka puhi ahi ma mua o 40 mm i kēlā me kēia minuke; No nā laʻana ma lalo o 3 mm mānoanoa, ʻoi aku ka nui o ke ahi ma lalo o 70 mm i kēlā me kēia minuke; A i ʻole e kinai i mua o ka hōʻailona 100 mm.
V-2: Ma hope o ʻelua mau hoʻāʻo puhi ahi he 10 kekona ma ka laʻana, hiki ke pio ka lapalapa i 60 kekona, a hāʻule kekahi mau mea puhi.
V-1: Ma hope o ʻelua mau hoʻāʻo puhi ahi he 10-kekona ma ka laʻana, hiki ke pio ka lapalapa i 60 kekona, ʻaʻole hiki ke hāʻule nā mea puhi.
V-0: Ma hope o ʻelua mau hoʻāʻo puhi ahi he 10 kekona ma ka laʻana, hiki ke pio ka lapalapa i 30 kekona, ʻaʻole hiki ke hāʻule nā mea puhi.
ʻO kēia nā wahi ʻike maʻamau e pili ana i nā adhesives i hoʻokaʻawale ʻia e siway, Shanghai Siway Building Materials Co., Limited i hoʻokumu ʻia ma 1984, I kēia manawa, loaʻa iā ia ka ISO9001: 2015 hōʻoia ʻōnaehana maikaʻi honua a me ka ISO14001 hōʻoia hoʻokele ʻōnaehana ʻōnaehana a me nā palapala ʻē aʻe.
