Netsika, vanhu vanowanzo shandisa bakelite, magetsi, nayiloni, mapurasitiki, rabha, ceramic nezvimwe zvinhu zvinodzivirira kupisa semidziyo yemagetsi inonzi matrix pamwe chete inonzi bakelite electrical appliances. Ndiyo connector yemagetsi inodiwa pakati pemudziyo nemagetsi, kana kuti switch inovhura nekuvhara circuit. Midziyo yeBakelite inonyanya kusanganisira chibatiso chemarambi, wire box, switch, plug, socket nezvimwewo. Kugadzirwa kwerudzi urwu rweZvibato zvepani zveBakelite yakakura, kushandiswa kwakasiyana-siyana, ndiyo inonyanya kushandiswa mumhuri yemidziyo yemagetsi yemumba.
Mavambo ezvinhu zvebhakelite
Zvinobuda mumiti mimwe zvinowanzogadzira maresini, asi amber idura remaresini, uye shellac, kunyange zvazvo ichionekwawo semaresini, idura rinobudiswa nezvipembenene zveshellac pamiti. Pendi yeShellac, yakagadzirwa neshellac, pakutanga yaingoshandiswa sechinochengetedza huni, asi nekugadzirwa kwemamota emagetsi yakava pendi yekutanga inochengetedza huni. Zvisinei, muzana remakore rechi20, magetsi akanga asisagone kuwanikwa nezvigadzirwa zvechisikigo, zvichiita kuti patsvagwe dzimwe nzira itsva uye dzakachipa.
Muzana remakore rechi19, nyanzvi yemakemikari yekuGermany A. Bayer yakatanga kuona kuti phenol ne formaldehyde zvinogona kuumba bundu rakatsvuka kana kuti gunk kana zvapiswa pasi pemamiriro eacidic, asi kuedza uku kwakamiswa nekuti zvaisagona kucheneswa nenzira dzechinyakare.
Muzana remakore rechi20,Baekelandnevabatsiri vake vakaitawo tsvakurudzo iyi, pakutanga vaine tariro yekugadzira pendi inodziisa kupisa panzvimbo pemaresini echisikigo. Mushure memakore matatu ekushanda nesimba, pakupedzisira muzhizha ra1907, havana kungogadzira pendi inodziisa kupisa chete, asiwo vakagadzira purasitiki chaiyo yakagadzirwa, Bakelite. Inozivikanwa sebakelite.
Rimwe zuva mumwedzi wakatevera, nyanzvi yemakemikari yekuGermany Beyer, achiita bvunzo dze phenol ne formaldehyde muflask, akawana kuti chinhu chinonamira chakanga chaumbwa mukati.
Mushure memakore akawanda ekuedza, zvakazoonekwa kuti zvaimbove "zvinonetsa" zvava "kufadza". Phenolic hainyure mvura, kupisa hakuchinji, ine simba remakanika. Zviri nyore kugadzirisa, asi inewo insulation yakanaka, iyo iri kungobuda muindasitiri yemagetsi. Ichi chigadzirwa chikuru. Saka, inoshandiswa zvakanyanya mukugadzira mabhureki emagetsi, maswichi emwenje, zvibatiso zvemarambi, nharembozha nezvimwe zvemagetsi, izvo zvakazotumidzwa zita rekuti bakelite. Zvisinei, tinoda kuizivisa kuti inoshandiswa muindasitiri yemidziyo yekubikira, zvichiita kuti ivemibato yepani,mibato yehariTine mhando dzakasiyana dzemibato yekubikira yakagadzirwa neBakelite.
