Ezomkhosi kunye nokuhamba ngenqwelomoya PCB zihlala zixhomekeke kwiimeko ezibi zokusingqongileyo, kubandakanya amaqondo obushushu aphezulu / anyukayo, ukufuma okugqithileyo kunye nokufuma. Ngapha koko, bahlala bevezwa ziikhemikhali ezirhabaxa, izisombululo zehydrocarbon, uthuli kunye nezinye izinto ezingcolisayo. Yi-PCB kuphela eqokelelwe kwizinto ezisemgangathweni ophezulu ezenziweyo kusetyenziswa iindlela ezichanekileyo zokuvelisa ezinokumelana neemeko ezinzima kwizicelo zasemkhosini nakwi-aerospace.

Uyila njani i-PCBS yomkhosi kunye neyokuhamba ngenqwelomoya

Xa kuthelekiswa neebhodi eziqhelekileyo, ii-PCBS zithetha ukuba ukusetyenziswa kwezomkhosi kunye ne-aerospace kufuna ukuqhubekeka okukhethekileyo kuyilo, ukwenziwa kunye nendibano.

Xa kuhlanganiswa i-PCBS yesicelo somkhosi kunye nokuhamba ngenqwelomoya, amanqaku ongezelelweyo kufuneka abandakanywe. Ezinye zezi zibandakanya:

L Sebenzisa ubushushu obuchithayo xa kufanelekile.

L Yongeza ukhuselo olongezelelekileyo kunye nomhlaba kwintambo ebalulekileyo.

L Coat PCBS enomgangatho ophezulu wokutshiza i-acrylic ukukhusela kwiindawo ezinobungozi.

Sebenzisa izinto ezinokubalula emkhosini endaweni yezinto zorhwebo.

L Sebenzisa iindlela zokuphelisa ezifanelekileyo.

L Khetha ngononophelo izinto kunye nezinto ezinokumelana namaqondo obushushu aphezulu. Oku kubandakanya iPyralux AP, i-epoxy laminates (umzekelo i-FR408) kunye nezinto ezahlukeneyo zentsimbi.

L Sebenzisa izixhobo zokugqiba ezinokuthenjwa ukomeleza ukhuseleko kwiimeko ezinzima. Ezona zinto zixhaphakileyo zokuhombisa zisetyenziswa kwindibano ye-PCB yomkhosi kunye nokuhamba ngenqwelomoya kubandakanya:

L Imveliso ye-PCBS yomkhosi kunye neyokuhamba ngenqwelomoya ehambelana nemil-PRF-31032, MIL-PRF-50884 kunye neMIL-PRF-55110 imigangatho.

L Nceda uqinisekise amandla okugoba, amandla ebhondi, ububanzi bocingo, ubukhulu, isisombululo, ubukhulu bezinto zokukhusela kunye ne-dielectric ngaphambi kokuthunyelwa. Qiniseka ukuba ukulungele ukuzisebenzisa kwimeko zorhwebo ezirhabaxa.

Ukugcina umgangatho kunye nokuzinza kubaluleke kakhulu xa kuyilwa ibala lezomkhosi kunye neebanga le-PCBS. Ukungaphumeleli kwe-PCB kunokuchaphazela ngokubonakalayo ukusebenza kwesicelo kwaye ngenxa yoko impumelelo yomsebenzi wonke.
