I-Evolution of PCBs: Ukusuka Ekuqalweni Kuya Enhliziyweni Yobuchwepheshe Banamuhla

Amabhodi Esifunda Aphrintiwe (ama-PCB) asehambe ibanga elide kusukela ekuqaleni kwawo kwekhulu lama-20, avela ngokusungula izinto ezintsha kanye nentuthuko yezobuchwepheshe ewalolonge abe yitshe legumbi lomhlaba wanamuhla wedijithali. Umlando wama-PCB uxhumene kakhulu nezikhathi ezibalulekile emlandweni, ikakhulukazi iMpi Yezwe II kanye nentuthuko yezimboni yangemva kwempi, kanye nentuthuko esheshayo kwezogesi engxenyeni yokugcina yekhulu lama-20. Ake sijule ngokuthi ama-PCB avele kanjani kusukela esidingweni sangesikhathi sempi ukuya engxenyeni ebalulekile kubuchwepheshe besimanje.

Izindlela Ezintsha Zokuqala kanye ne-Wartime Catalyst: 1900-1950

Umqondo wesekethe ephrintiwe uhlehlela emuva ekuqaleni kwawo-1900, nomsebenzi wokuphayona owenziwa abasunguli abafana no-Albert Hanson no-Charles Ducas, abahlola umqondo wamakhondatha ayisicaba ezindaweni ezifaka i-insulating. Ngo-1903, u-Hanson wenza isiphakamiso sendlela yokuqala yamasekhethi anezingqimba eziningi zamasistimu ocingo, kuyilapho ilungelo lobunikazi likaDucas ngo-1927 lalihlanganisa indlela yokunyathelisa amasekhethi kagesi kusetshenziswa uyinki oqhubayo, ebeka isiteji sentuthuko yesikhathi esizayo. Kodwa-ke, le mibono emisha yakuqala yayiyithiyori futhi ayizange yamukelwe kabanzi.

Impumelelo eyashintsha ngempela ama-PCB aba ubuchwepheshe obusebenzayo yenzeka phakathi neMpi Yezwe II, sibonga u-Paul Eisler, unjiniyela wase-Austria. Ebalekela ukushushiswa kwamaNazi, u-Eisler waletha ubuchwepheshe bakhe e-UK, lapho athuthukisa khona i-PCB yokuqala esebenza ngokugcwele ekuqaleni kwawo-1940. Ukuqamba okusha kuka-Eisler kwakuhilela ukuphrinta isekethe ye-foil yethusi kusisekelo esiqiniswe yingilazi esinga-conductive, okwanciphisa kakhulu ubukhulu nobunkimbinkimbi bezintambo kumishini kagesi.

Phakathi nempi, amasosha aseMelika naseBrithani asheshe abona amandla alobu buchwepheshe ukuze busetshenziswe ezinhlelweni ezibucayi zokuxhumana nezikhali. Ama-PCB anikeze amandla ukukhiqizwa okukhulu kwezinto ezinokwethenjelwa, ezilinganiselwe zemisakazo yezempi, ama-proximity fuse, namasistimu e-radar.
