Yini okufanele inake i-PCB enezingqimba eziningi?

Ubukhulu obuphelele nenani lezendlalelo zebhodi lezendlalelo eziningi ze-PCB kunqunyelwe izici zebhodi le-PCB. Amabhodi akhethekile anqunyelwe ukushuba kwebhodi okunganikezwa, ngakho umklami kufanele acabangele izici zebhodi zenqubo yokuklama ye-PCB kanye nemikhawulo yobuchwepheshe bokucubungula i-PCB.

Izinyathelo zokuqapha zenqubo yokuhlanganisa izendlalelo eziningi

I-Laminating iyinqubo yokuhlanganisa ungqimba ngalunye lwebhodi lesifunda libe lilonke. Yonke inqubo ihlanganisa ukucindezela kokuqabula, ukucindezela okugcwele kanye nokucindezela okubandayo. Ngesikhathi sesiteji sokucindezela ukuqabula, i-resin ingena endaweni ebophayo futhi igcwalise izikhala kulayini, bese ingena ngokucindezela okugcwele ukuze ibophe zonke izikhala. Okubizwa ngokuthi ukucindezela okubandayo ukupholisa ibhodi lesifunda ngokushesha futhi ugcine usayizi uzinzile.

Inqubo ye-Laminating idinga ukunaka izinto, okokuqala ekwakhiweni, kufanele ihlangabezane nezidingo zebhodi elingaphakathi elingaphakathi, ikakhulukazi ukushuba, usayizi womumo, imbobo yokubeka, njll., Idinga ukuklanywa ngokuhambisana nezidingo ezithile, izidingo zebhodi elingaphakathi elingaphakathi alikho elivulekile, elifushane, elivulekile, alikho i-oxidation, alikho ifilimu esele.

Okwesibili, lapho u-laminating amabhodi we-multilayer, amabhodi angaphakathi angaphakathi adinga ukuphathwa. Inqubo yokwelapha ihlanganisa ukwelashwa kwe-black oxidation kanye nokwelashwa kwe-Browning. Ukwelashwa kwe-oxidation ukwenza ifilimu ye-oxide emnyama ecwecweni lethusi elingaphakathi, futhi ukwelashwa okunsundu kuwukwenza ifilimu ephilayo kucwecwe lwethusi lwangaphakathi.

Okokugcina, lapho i-laminating, sidinga ukunaka izindaba ezintathu: izinga lokushisa, ingcindezi kanye nesikhathi. Izinga lokushisa ngokuyinhloko libhekisela ekuncibilikeni kwezinga lokushisa kanye nezinga lokushisa le-resin, izinga lokushisa elimisiwe le-hot plate, izinga lokushisa langempela lezinto kanye nokushintsha kwezinga lokushisa. Le mingcele idinga ukunakwa. Ngokuqondene nokucindezela, umgomo oyisisekelo uwukugcwalisa umgodi we-interlayer nge-resin ukuze ukhiphe amagesi e-interlayer kanye nokuguquguquka. Imingcele yesikhathi ilawulwa ikakhulukazi isikhathi sokucindezela, isikhathi sokushisa nesikhathi sejeli.
