Momwe Mabedi a Granite Amathandizira Kukhazikika mu Makina Okhomerera a PCB?

 

Pakupanga makina osindikizira (PCB), kulondola komanso kukhazikika ndikofunikira. Bedi la granite ndi chimodzi mwazinthu zofunika kwambiri zomwe zimathandizira kwambiri magwiridwe antchito a makina okhomerera a PCB. Kugwiritsa ntchito miyala ya granite m'makinawa sikungochitika chabe; ndi kusankha njira ndi ubwino ambiri.

Granite imadziwika chifukwa cha kuuma kwake kwakukulu komanso kachulukidwe, zomwe ndizofunikira kwambiri pakusunga bata panthawi yokhomerera. Pamene PCB kukhomerera makina akugwira ntchito, ndi pansi pa mphamvu zosiyanasiyana ndi kugwedera. Mabedi a makina a granite amayamwa bwino kugwedezeka uku, kuchepetsa kusuntha komwe kungapangitse kuti nkhonya ikhale yolakwika. Kukhazikika kumeneku kumatsimikizira kulumikizidwa bwino kwa mabowo a nkhonya, zomwe ndizofunikira kwambiri pakugwira ntchito komaliza kwa PCB.

Kuonjezera apo, bedi la granite limagonjetsedwa ndi kuwonjezereka kwa kutentha. Izi ndizofunikira kwambiri m'malo omwe amasinthasintha pafupipafupi. Mosiyana ndi zipangizo zina zomwe zingakule kapena kugwirizanitsa ndi kusintha kwa kutentha, granite imasunga miyeso yake, kuonetsetsa kuti ikugwira ntchito nthawi yayitali. Kukhazikika kumeneku ndikofunikira pakupanga kwamphamvu kwambiri, chifukwa ngakhale kupatuka pang'ono kumatha kuyambitsa zovuta zazikulu.

Kuphatikiza apo, bedi la granite ndi losavuta kukonza ndikuyeretsa. Malo ake opanda porous amalepheretsa kudzikundikira kwa fumbi ndi zinyalala zomwe zingakhudze ntchito ya makina. Mlingo uwu waukhondo umangowonjezera moyo wa makinawo, komanso umathandizira kuti ma PCB apangidwe bwino.

Mwachidule, kuphatikiza bedi la granite mu makina okhomera a PCB ndikusintha masewera. Bedi la granite limawonjezera kulondola komanso kuchita bwino kwa njira yopangira PCB popereka kukhazikika kwapamwamba, kukana kukulitsa kwamafuta komanso kukonza kosavuta. Kufunika kwazinthu zatsopanozi sikunganenedwe mopambanitsa pomwe makampaniwa akupitilizabe kusinthika, ndikupanga granite kukhala chinthu chofunikira kwambiri pakupanga kwamakono kwa PCB.
