Pono ka hapa nui o nā ʻenekini uila e kūʻai aku i ka papa mehao hao, a he mea ʻawaʻawa paha ka ipu hao?
1. He mea make anei ka ipu hao me ka hao?
Ke hoʻopiʻi nei kekahi mau mea hoʻohana pūnaewele no ka hoʻohana ʻana i ka tin solder a puni ka makahiki ma ka hale hana PCB.Ua manaʻo ʻo ia ua hoʻomaka ʻo ia e hōʻoluʻolu, a ua ʻōhū iki kona ʻōpū.He lāʻau make kepau?
ʻO ka mea ʻoiaʻiʻo, pili nō hoʻi ia i ka uea solder i hoʻohana ʻia no ke kūʻai ʻana me ka hao hao hao ke alakaʻi ʻole a ʻaʻole ma ka hana, a pono e nānā mau ke alakaʻi koko.Inā ʻaʻole i ʻoi aku ma mua o ka maʻamau, ʻaʻohe pilikia iki.He mea ʻawaʻawa paha ka ipu hao?
ʻO ka ʻōlelo maʻamau, inā mālama ʻia ka pale a me ke kūʻai ʻana i nā mea maka e like me nā kūlana ʻāina, ʻaʻole e hoʻopōʻino nui ʻia ka tin soldering.I kēia manawa, hoʻohana ʻia nā huahana alakaʻi ʻole.
He mea ʻawaʻawa ke kēpau.ʻO ka ʻai nui ʻana e ke kino o ke kanaka ke kumu o ka make kepau.Hiki ke hoʻopili ʻia ka ʻai haʻahaʻa haʻahaʻa i ka naʻauao kanaka, ka ʻōnaehana nerve a me ka ʻōnaehana hānau.ʻO ka huila o ka tin a me ke kēpau ka mea hoʻohana maʻamau.Loaʻa iā ia ka conductivity metala maikaʻi a me ka helu heheʻe haʻahaʻa.No laila, ua hoʻohana ʻia i ka ʻenehana welding no ka manawa lōʻihi.No loko mai o ke kēpau kona mea make.Hiki ke alakaʻi maʻalahi i ka uahi kēpau i hana ʻia e ka ipu hao.
Hiki i ke kēpau metala ke hana i nā pūhui kepau, i helu ʻia a pau he mau mea ʻino.I loko o ke kino o ke kanaka, e hoʻopilikia ke kēpau i ka ʻōnaehana ʻōhua waena a me ka puʻupaʻa.Ua hōʻoia ʻia ka ʻona o ke kaiapuni o ke alakaʻi i kekahi mau meaola.Ua hiki i ka 10 μG / dL a i ʻole ka nui o ke alakaʻi koko e hoʻopuka i nā hopena biochemical koʻikoʻi.Inā hōʻike ʻia no ka manawa lōʻihi, ʻoi aku ka nui o ke kahe o ke alakaʻi koko ma mua o 60 ~ 70 μG / dl e hōʻeha i ka lāʻau make.
He mea make ke kepau.ʻAʻole liʻiliʻi ka hopena o ka pā hao i ke kino.ʻO nā metala maʻamau e make inā nui loa.I ka wā e hoʻoheheʻe ʻia ai ke kī, aia ka uahi, aia kahi mea ʻino i ke kino.I ka hana ʻana, ʻoi aku ka maikaʻi o ka ʻaʻahu ʻana i ka maka, akā e mau ana kekahi hopena.ʻOiaʻiʻo, inā hiki iā ʻoe ke hoʻohana i ka uea solder lead-free, e ʻoi aku ka palekana ma mua o nā mea me ke kēpau.
2、 He mea ʻawaʻawa paha ka solder me ke kēpau?
ʻO ka mea i hoʻohana ʻia no ka hoʻoheheʻe ʻana i ke kini me ka hao hao ʻeleʻele ʻo ia ka uea solder.ʻOiai ʻo kāna mea nui he tin, aia kekahi mau metala ʻē aʻe.Hoʻokaʻawale ʻia ʻo ia i ke alakaʻi a me ke alakaʻi ʻole (ʻo ia ke ʻano palekana kaiapuni).Me ka hoʻokomo ʻana o ka EU ROHS maʻamau, ʻoi aku ka nui o nā hale hana wiliwili PCB e koho i ke alakaʻi-ʻole a me ke kaiapuni.Ke hoʻololi mālie ʻia nei ka uea solder kepau, ʻaʻole ia e pili i ke kaiapuni a ʻaʻole hiki ke lawe ʻia aku.ʻO ka pākuʻi solder manuahi ʻole ke alakaʻi, ka uea kepau-ʻole a me ka pahu pahu kepau ʻole nā huahana nui ma ka mākeke i kēia manawa.
No ka ma'alahi'ana: he mea 'awa'awa ka ipu hao i ho'ohana 'ia ma muli o kona wahi hehe'e ha'aha'a, he 60% ke kēpau a me ka 40% tin.ʻO ka hapa nui o ka ipu hao ma ka mākeke he hakahaka a loaʻa ka rosin, no laila ua manaʻo ʻia e hoʻoheheʻe ʻia ke kinoea āu i ʻōlelo ai i ka wā e heheʻe ai ka rosin i loko o ka ipu hao i ka wā wili.ʻO ke kinoea hoʻoheheʻe ʻia mai ka rosin he mea ʻawaʻawa hoʻi.Honi kino keia kinoea.
ʻO ka uwahi kepau ke kumu nui o ka pōʻino o ka pā.ʻO ke kēpau hoʻoheheʻe ʻole ʻia kekahi nui o ke kēpau.ʻO ka palena o ka uahi kēpau ma gbz2-2002 he haʻahaʻa loa a ʻona, no laila pono e pale ʻia.Ma muli o ka pōʻino o ke kaʻina hana welding i ke kino kanaka a me ke kaiapuni, ma ʻEulopa, ua hoʻokō ʻia ka pale o nā limahana welding a me ka pale o ke kaiapuni ma ke ʻano o ke kānāwai.ʻAʻole ʻae ʻia ka welding me ka ʻole o nā hana pale.I ka maʻamau ISO14000, aia nā ʻōlelo aʻoaʻo e pili ana i ka mālama ʻana a me ka pale ʻana i ka pollution i hana ʻia i nā loulou hana.
Aia ke kēpau i loko o ka tin.I ka wā ma mua, aia ke kēpau i ka uwea solder.Hoʻokaʻawale ʻia ʻo Solder ma ke ʻano he pou pōʻino ʻoihana (ma ka helu aupuni o nā maʻi ʻoihana);I kēia manawa, hoʻohana kā mākou ʻoihana maʻamau i ka uea solder me ke alakaʻi ʻole.ʻO ka mea nui ʻo ka tin, a ʻo ke kikowaena o ka maʻi a me ka pale ʻana i ke tin dioxide;ʻAʻole ia i loko o ka papa inoa o nā maʻi ʻoihana.
ʻO ka ʻōlelo maʻamau, ʻaʻole ʻoi aku ka nui o ka uahi alakaʻi ma ke kaʻina alakaʻi ʻole ma mua o ka maʻamau, akā aia kekahi mau pōʻino ʻē aʻe i ka pā hao.No ka laʻana, he mau pōʻino ko ka soldering flux (rosin substances), pono e ʻike ʻia e like me ke kūlana kikoʻī.Hiki i nā limahana ke nānā maʻamau i ka ʻike a me ka ʻāpana o ka tin i puʻunaue ʻia, i hiki ke kākau maikaʻi ʻia a koi i ka ʻoihana e hoʻoponopono (hiki iā lākou ke hāʻawi i nā manaʻo i ka hui kalepa kūloko o ka hale hana).Inā loaʻa i ke kēpau ke kēpau, pono ia e pōʻino i kou olakino.I ka wā lōʻihi, hōʻiliʻili lākou i loko o ke kino a hoʻopilikia nui i ka ʻōnaehana pale o ka ʻōnaehana nerve.
Lead free solder wire is environmentally friendly, but lead-free solder wire is also harmful to human body.ʻAʻole alakaʻi ʻole ke alakaʻi haʻahaʻa o ka uea solder lead-free.Ke hoʻohālikelike ʻia me ka uea solder kepau, ʻoi aku ka liʻiliʻi o ka pollution i ke kaiapuni a me ke kino o ke kanaka ma mua o ka uea solder kepau.ʻO ke kinoea i hana ʻia i ka wākūʻai ʻanahe mea ʻawaʻawa, me ka aila rosin, zinc chloride a me nā mahu kinoea ʻē aʻe.
3、 Pehea e pale ai i ka hao hao a me ka uea solder mai ka make
ʻO ka mea mua, pono nā hale hana PCB e hoʻohana i ka RoHS tin uea i ka wā e kūʻai ai i nā ʻāpana me ka hao soldering uila, a hana i kahi hana maikaʻi o ka pale ʻana: no ka laʻana, ʻaʻahu i nā mīkina lima, masks a i ʻole ke kinoea masks, e hoʻolohe i ka ventilation i ka wahi hana, loaʻa kahi exhaust maikaʻi. ʻōnaehana, e hoʻolohe i ka hoʻomaʻemaʻe ʻana ma hope o ka hana, a hiki i ka inu waiu ke pale aku i ka ʻawaʻawa o ke kēpau i ka tin soldering.
1. No ka hoʻomaha no kekahi manawa: maʻamau, pono ʻoe e hoʻomaha ma kahi o 15 mau minuke no hoʻokahi hola e hoʻopau i ka luhi, no ka mea ʻoi aku ka maikaʻi o ke kū'ē ʻana ke luhi ʻoe.
2. E hoʻemi i ka uahi a inu i ka wai, hiki ke hoʻopau i ka hapa nui o nā mea ʻino i komo i ka lā.
3. E inu i ka mung bean soup a i ʻole ka wai meli ma mua o ka moe ʻana, hiki ke hōʻemi i ke ahi a kōkua i kou ʻano, a hiki i ka mung beans a me ka meli ke hoʻopau i ka nui o ke kēpau a me ka radiation.
4. E pale i ka radiation a ho'āʻo e pale i ke kali ʻana i nā kelepona paʻalima.
5. Hiki iā ʻoe ke hoʻomālamalama i ka hao hao a hoʻāʻo e hoʻohana i ke poʻo welding PPD.Ma kēia ala, i ka hiki ʻana o ka mahana, hiki iā ʻoe ke hoʻohana i ka ʻaila welding liʻiliʻi a me ka rosin e hōʻemi i ka pōʻino i kou kino,
6. I ka wā e puhi ai ka ʻaila a me ka uahi, e hoʻāʻo e palaki i ka lewa me kou poʻo ma ka ʻaoʻao, a e hoʻāʻo e paʻa i kou hanu ke palaki ʻoe i ka wai.
7. E hoʻemi i ka wai Tianna, e hoʻohana i ka waiʻona hou aʻe, a e palaki hou me ka waiʻona no kekahi manawa.Ua aneane like ka hopena.
8. Holoi i kou mau lima.
9. E auau ma mua o ka moe.E ho'āʻo e moe a ala aʻe i ke kakahiaka nui e hōʻoia i ka hiamoe kūpono.I ka wā e hiamoe maikaʻi ai ʻoe, hiki ke hoʻokuʻu ʻia nā haumia me kou kino.
10. E hana me nā maka.
