Ko te rerekētanga i waenganui i HASL me HASL mata-free

wā: 2018-08-13

Ko tētahi o nga tukanga nuitia whakamahia hoki he mata maimoatanga o papa PCB: HASL, ka karanga hoki "whakaōritenga hau wera", i te mea he tukanga nui i roto i te hanga o te papa iahiko PCB. Ko te whakapiringa matua o papa iahiko PCB he HASL mata-free. E rua ngā momo o te mata-rehu tine, e hoki nuitia whakamahia. Kei te whakamahia whānuitia ratou i roto i ngā kaiwhakanao poari ara iahiko. Ko te kounga o te rehu tine tika pānga te kounga o kiritaki muri \ 'fehokotaki'anga, na kua meinga rehu tine te arotahi o te mana kounga mō kaiwhakanao poari ara iahiko. , i raro ki te whakauru i te āhuatanga, me te pā ana mōhiotanga taketake o te PCB momo rehu tine.

1.āhuatanga maimoatanga rehu tine mata PCB:

Riringi tine i roto i te poari PCB ara iahiko ko te tukanga tino whakamahia nuitia. Ko atu mahi tenei ahua o te tukanga. He mahi fehokotaki'anga pai, pai pānga anti-hāora, a ko ngā utu te utu. E hoki e rua ngā momo o te mata, me te mata-free rerekētanga i roto i te PCB poari ara iahiko:

2.maimoatanga mata PCB momo rehu tine:

 tuatahi, mata-free HASL. HASL Lead-free ko he tukanga taiao. Ko reira tino kino ki te tinana tangata. Ko reira ano hoki he tukanga taunaki i tenei wā. Te ihirangi mata i roto i te mata-free tine he kore neke atu i 0.5, me te HASL mata-free he ira whakakoero teitei, kia e he u te tahi tūhoto. roto i te ngako, mata tine i ringihia me tine te rehu mata-free ko te tukanga. Anake ko rerekē te viivii ore o te mata. Lead-free tine ko te taiao ake taiao me te haumaru hoki te tinana tangata, a ko reira ano hoki te au whanaketanga i roto i te heke mai. E tūtohu ana kia whakamahi koe i reira. Kua whakaurua nga āhuatanga me tōnounoú o nga momo e rua o te tukanga hasl me mata-free hasl. I roto ia ratou, He ngāwari ki te whakamahi hasl, engari ko te reira haumaru, taiao, me te kino ki te tinana tangata. Na reira, e tūtohu ana ki te whakamahi i mata-free hasl, kore-paitini, me te mahaki, Ko hoki te tukanga maimoatanga mata taunaki tēnei wā.

    tuarua, HASL. tikanga te tine mata-riringi pera-ka karanga e rite tine te rite ki te tetahi ōwehenga. ka whakanui i Lead te mahi o te waea tine i roto i te tukanga fehokotaki'anga. Ko te pai atu i te waea tine mata-free waea Lead-tine, engari he paitini mata, me te kua arahina. he kino ki te tangata Lead; Ko raro atu i mata-free ārahi pāmahana eutectic. Tüturu, tei reira ki runga ki te hanganga o te koranu mata-free. Ko te eutectic rite SNAGCU ko 217 degrees, me te pāmahana whakapiringa he eutectic pāmahana me 30 ki 50 degrees. Tei te reira i runga i te whakatikatikanga tūturu. Ko te eutectic nekehanga 183 degrees. Lead i roto i aunoa kaha, wherikotanga, etc. Ko te pai atu i mata-free. Therefore, e kore te mea te reira taiao ki te whai ārahi tine, a i reira ko tetahi rerekētanga ki te tiaki taiao i parauhia e te ao. Therefore, whanau arahNa reira rehu tine i.

    Na me pehea ki te wehewehe i waenganui i ārahi me te maimoatanga mata mata-free, Ko te kuware tenei, tango i te wahi o te pepa ma ki ata horoia te papa, te tūnga o te tine, ki te he te reira pango, reira he mata tine rehu, kahore pango he kahore tine i ringihia Lead.
