Kuyerekeza Zigawo za Granite ndi Chitsulo mu Mapulogalamu Obowola a PCB.

 

Pakupanga bolodi losindikizidwa (PCB), kulondola ndi kulimba ndikofunikira kwambiri. Mbali yofunika kwambiri pa ndondomekoyi ndi kusindikiza PCB, ndipo kusankha zinthu zomwe zasindikizidwa kungakhudze kwambiri ubwino ndi magwiridwe antchito a chipangizocho. Zipangizo ziwiri zomwe zimagwiritsidwa ntchito kwambiri pankhaniyi ndi granite ndi chitsulo, chilichonse chili ndi ubwino ndi zovuta zake.

Zigawo za granite zimadziwika chifukwa cha kukhazikika kwawo komanso kulimba kwawo. Kuchuluka kwa miyala yachilengedwe kumapereka maziko olimba omwe amachepetsa kugwedezeka panthawi yoponda, motero kumawonjezera kulondola ndikuchepetsa kuwonongeka kwa zida zoponda. Kukhazikika kumeneku ndikothandiza makamaka pakugwiritsa ntchito mwachangu kwambiri, komwe ngakhale kusuntha pang'ono kungayambitse kusakhazikika bwino komanso zolakwika. Kuphatikiza apo, granite imalimbana ndi kutentha kwambiri, zomwe zimapangitsa kuti kutentha kugwire ntchito bwino pa kutentha kosiyanasiyana, zomwe ndizofunikira kwambiri m'malo omwe kutentha kumakhala kovuta kupanga.

Koma zigawo zachitsulo, zimakondedwa chifukwa cha mphamvu ndi kulimba kwawo. Zigawo zachitsulo sizimaphwanyika mosavuta kuposa granite, zomwe zimapangitsa kuti zikhale zosankha zodalirika zopangira zinthu zambiri. Kuphatikiza apo, zigawo zachitsulo zimatha kupangidwa mosavuta ndikusinthidwa kuti zikwaniritse zofunikira zinazake, zomwe zimapangitsa kuti mapangidwe azikhala osinthasintha omwe granite sangagwirizane nawo. Komabe, zigawo zachitsulo zimatha kuchita dzimbiri komanso dzimbiri, zomwe zingakhale zovuta kwambiri m'malo omwe ali ndi chinyezi kapena mankhwala.

Poyerekeza momwe granite ndi chitsulo zimagwirira ntchito popaka ma PCB stamping, chisankho chomaliza chimadalira zosowa zenizeni za njira yopangira. Pa ntchito zomwe kulondola ndi kukhazikika ndizofunikira kwambiri, granite ikhoza kukhala chisankho chabwino kwambiri. Mosiyana ndi zimenezi, pa ntchito zomwe zimafuna kulimba komanso kusinthasintha, chitsulo chingakhale chopindulitsa kwambiri. Kumvetsetsa makhalidwe apadera a chinthu chilichonse ndikofunikira kwa opanga omwe akufuna kukonza njira zawo zopangira PCB.
