Iingubo zePCB (iBhodi yeSekethe eShicileleyo) zidlala indima ebalulekileyo ekukhuseleni iisekethe kwiindawo ezirhabaxa zangaphandle. Nangona kunjalo, kwezinye iimeko, kusenokuba yimfuneko ukususa i-PCB yokwambathisa ngeenjongo zokulungisa okanye uhlengahlengiso. Kwesi sikhokelo sibanzi, siza kukuhamba ngamanyathelo okukhupha ngokukhuselekileyo nangempumelelo iiyaleko zePCB. Ngobuchule obufanelekileyo kunye nezixhobo, unokususa ngempumelelo i-coating ngaphandle kokubangela nawuphi na umonakalo kwisekethe ethambileyo.
1. Qonda ukutyabeka kwePCB
Phambi kokuntywila kwinkqubo yokususa, kufanelekile ukuqonda iintlobo zeengubo zePCB onokuthi udibane nazo. Iingubo eziqhelekileyo ziquka i-acrylic, i-epoxy, i-polyurethane, i-silicone, kunye ne-parylene. Uhlobo ngalunye luneempawu zalo kwaye lufuna iindlela ezithile zokususa. Ngaphambi kokuqala inkqubo yokususa, kubalulekile ukuchonga i-coating esetyenziswe kwi-PCB ukuqinisekisa ukuba indlela efanelekileyo iyasetyenziswa.
2. ImiGaqo yoKhuseleko
Ukhuseleko kufuneka lube yeyona nto iphambili yakho xa usebenza ngeengubo zePCB. Qinisekisa ukuba unxibe iiglavu, iiglavu, kunye nemaski yokuphefumla ukuze uzikhusele kumsi wekhemikhali. Kwakhona, sebenza kwindawo engena umoya ukuze unciphise ukuchanabeka kwizinto eziyingozi. Gcina isicima-mlilo sikufutshane kwaye ulandele zonke izikhokelo zokhuseleko kunye nemiyalelo enikezwe ngumenzi wepeyinti.
3. Khetha isixhobo esifanelekileyo
Ukususa ngokufanelekileyo ukutyabeka kwePCB, udinga iseti ekhethekileyo yezixhobo. Oku kunokubandakanya izikhululo zokuvuselela umoya oshushu, imipu yokutshisa, iintsimbi zokuthambisa, iimela ezichanekileyo, kunye nezisombululo zokucoca iPCB. Ukukhethwa kwesixhobo kuxhomekeke kuhlobo lwengubo kunye nobukhulu bendawo ofuna ukuyisusa.
4. Inkqubo yokucima inyathelo ngenyathelo
- Inyathelo loku-1: Lungisa iPCB ngokususa naziphi na iinxalenye, izihlanganisi okanye iingcingo ezinokuthintela inkqubo yokususwa kokugquma.
- Inyathelo lesi-2: Khangela uhlobo lokwaleka. Iingubo ze-Acrylic kunye ne-epoxy zihlala zithanjiswa kwaye zisuswe ngokusebenzisa umpu wokushisa okanye isikhululo sokuvuselela umoya oshushu. I-silicone okanye i-parylene coatings, ngakolunye uhlangothi, inokufuna i-strippers yeekhemikhali okanye i-solvents ekhethekileyo.
- Inyathelo lesi-3: Fudumeza ngokucokisekileyo i-coat usebenzisa indlela efanelekileyo, uqinisekisa ukuba awugqithisi okanye uwonakalise i-PCB.
Inyathelo lesi-4: Usebenzisa imela echanekileyo okanye esinye isixhobo esifanelekileyo, cofa ngononophelo isambatho esithambileyo. Qaphela ukuba ungonakalisi ukujikeleza okungaphantsi.
- Inyathelo lesi-5: Emva kokususa ubuninzi bokugquma, sebenzisa isisombululo sokucoca i-PCB ukususa nayiphi na intsalela okanye intsalela yentsalela.
- Inyathelo lesi-6: Hlanza i-PCB ngokucokisekileyo nge-isopropanol okanye amanzi adibeneyo ukususa nayiphi na intsalela yesisombululo sokucoca.
- INYATHELO LESI-7: Vumela iPCB yome ngokupheleleyo phambi kokudibanisa kwakhona okanye ukwenza nawuphi na omnye umsebenzi.
5. Izilumkiso emva kokususwa
Emva kokususwa ngempumelelo kwe-PCB yokwaleka, kubalulekile ukuhlola ibhodi kuwo nawuphi na umonakalo onokwenzeka. Khangela nayiphi na imikhondo ephakanyisiweyo okanye eyonakeleyo, i-vias eyaphukileyo, okanye izinto ezonakeleyo. Ukuba kukho nayiphi na imiba efunyenweyo, kufuneka ilungiswe ngaphambi kokuba kuqhutyekwe nomsebenzi owongezelelweyo.
Ukususa ukutyabeka kwe-PCB kufuna umonde, ukuchaneka kunye nezixhobo ezifanelekileyo. Ngokulandela inyathelo ngenyathelo inkqubo echazwe kwesi sikhokelo, ungasusa ngokukhuselekileyo nangempumelelo iingubo zokwaleka kwiiPCBs. Khumbula ukuba uqaphele, ulandele izikhokelo zokhuseleko, kwaye uthathe amanyathelo ayimfuneko emva kokuchithwa kokuqinisekisa ukunyaniseka kwesekethe. Ukususwa kokwaleka okuvuyisayo!
