Mwachikhalidwe, anthu nthawi zambiri amagwiritsa ntchito bakelite, magetsi, nayiloni, pulasitiki, rabala, ceramic ndi zinthu zina zotetezera kutentha monga zida zamagetsi za matrix zomwe zimatchedwa zida zamagetsi za bakelite. Ndi cholumikizira chamagetsi chofunikira kwambiri pakati pa chipangizocho ndi magetsi, kapena switch yomwe imatsegula ndikutseka dera. Zipangizo za Bakelite zimaphatikizapo chogwirira nyali, bokosi la waya, switch, pulagi, soketi ndi zina zotero. Kupanga kwamtunduwuZogwirira za pani za Bakelite ndi yayikulu, kugwiritsa ntchito zinthu zosiyanasiyana, ndiye komwe kumagwiritsidwa ntchito kwambiri m'banja la zipangizo zamagetsi zapakhomo.
Chiyambi cha zinthu za bakelite
Kutuluka kwa madzi m'mitengo ina nthawi zambiri kumapanga utomoni, koma amber ndi chotsalira cha utomoni, ndipo shellac, ngakhale kuti imaonedwanso ngati utomoni, ndi malo osungidwa ndi tizilombo ta shellac pamitengo. Utoto wa shellac, wopangidwa kuchokera ku shellac, poyamba unkagwiritsidwa ntchito ngati chosungira matabwa, koma ndi kupangidwa kwa magalimoto amagetsi, utoto woyamba woteteza kutentha unagwiritsidwa ntchito. Komabe, m'zaka za m'ma 1900, magetsi sanathenso kupezeka ndi zinthu zachilengedwe, zomwe zinayambitsa kufunafuna njira zina zatsopano komanso zotsika mtengo.
M'zaka za m'ma 1800, katswiri wa zamankhwala wa ku Germany A. Bayer adapeza koyamba kuti phenol ndi formaldehyde zimatha kupanga msanga chotupa chofiirira kapena chofiirira zikatenthedwa pansi pa acidity, koma kuyesaku kunayimitsidwa chifukwa sikungathe kuyeretsedwa ndi njira zakale.
Mu zaka za m'ma 1900,Baekelandndipo omuthandiza ake nawonso adachita kafukufukuyu, poyamba ndi chiyembekezo chopanga utoto woteteza kutentha m'malo mwa utomoni wachilengedwe. Pambuyo pa zaka zitatu akugwira ntchito mwakhama, pomaliza pake m'chilimwe cha 1907, sanangopanga utoto woteteza kutentha, komanso anapanga pulasitiki yeniyeni yopangidwa, Bakelite. Imadziwika kuti bakelite.
Tsiku lina m'chaka chotsatira, katswiri wa zamankhwala wa ku Germany, Beyer, poyesa phenol ndi formaldehyde mu botolo, adapeza kuti chinthu chomata chinapangidwa mkati mwake.
Pambuyo pa zaka zambiri zoyesera, zapezeka kuti zomwe zinali "zokhumudwitsa" tsopano "zosangalatsa kwambiri". Phenolic simatuluka madzi, kutentha sikusinthasintha, ili ndi mphamvu inayake yamakina. Ndi yosavuta kuikonza, komanso ili ndi kutchinjiriza kwabwino, komwe kukubwera kumene kumakampani amagetsi. Ndi chinthu chachikulu kwambiri. Chifukwa chake, imagwiritsidwa ntchito kwambiri popanga mabuleki amagetsi, ma switch amagetsi, zogwirira nyali, mafoni ndi zina zamagetsi, zomwe zidatchedwa bakelite. Komabe, tikufuna kuyambitsa kuti imagwiritsidwa ntchito mumakampani ophikira mbale, zomwe zimapangitsa kuti ikhale ngatizogwirira za pani,zogwirira za mphikaTili ndi mitundu yosiyanasiyana ya zogwirira zophikira zopangidwa ndi Bakelite.
