Kugwiritsa ntchito bakelite

Pulasitiki ya phenolic, yomwe imadziwika kuti ufa wa bakelite, inapangidwa mu 1872 ndipo inayikidwa m'mafakitale ku 1909. Ndilo pulasitiki yakale kwambiri padziko lonse lapansi, dzina la pulasitiki lochokera ku phenolic resin, ndi imodzi mwa mapulasitiki ofunika kwambiri a thermosetting.Nthawi zambiri, imatha kugawidwa m'mapulasitiki osapangidwa ndi phenolic ndi mapulasitiki a phenolic laminated.Mapulasitiki osapangidwa ndi laminated phenolic amatha kugawidwa m'mapulasitiki opangidwa ndi phenolic ndi mapulasitiki oponderezedwa a phenolic.Amagwiritsidwa ntchito kwambiri ngati zida zotchinjiriza zamagetsi, zida za mipando, zofunikira za tsiku ndi tsiku, ntchito zamanja, mongachipolopolo chophika mpunga, bakelite chogwirira, kusintha Chalk, etc. Komanso, pali asbestos phenolic mapulasitiki makamaka ntchito asidi kukana, zomatira TACHIMATA pepala ndi nsalu kutchinjiriza, phenolic thovu mapulasitiki ndi uchi mapulasitiki kutchinjiriza matenthedwe ndi kutchinjiriza phokoso, etc.

Phenolic laminated pulasitiki imapangidwa ndi ma sheet filler ophatikizidwa ndi phenolic resin solution, yomwe imatha kupangidwa kukhala mbiri ndi mbale zosiyanasiyana.Malinga ndi zodzaza zosiyanasiyana zomwe zimagwiritsidwa ntchito, pali mapepala, nsalu, nkhuni, asibesitosi, nsalu zamagalasi ndi mapulasitiki ena opangidwa ndi laminated.Nsalu ndi magalasi mapulasitiki a phenolic laminated amakhala ndi makina abwino kwambiri, kukana mafuta ndi zinthu zina za dielectric.Amagwiritsidwa ntchito popanga magiya, zipolopolo zonyamula, mawilo owongolera, magiya opanda phokoso, ma bere, zida zamagetsi zamagetsi ndi zida zamagetsi zamagetsi.Mapulasitiki opangidwa ndi matabwa ndi oyenera kunyamula ndi magiya pansi pa zokometsera zamadzi ndi kuziziritsa.Nsalu ya asibesitosi yopangidwa ndi laminated pulasitiki imagwiritsidwa ntchito makamaka pazigawo zomwe zimagwira ntchito kutentha kwambiri.

Phenolic fiber yooneka ngati psinjika pulasitiki imatha kutenthedwa ndikuwumbidwa m'magawo osiyanasiyana amagetsi ndi magetsi, okhala ndi magetsi abwino kwambiri, kukana kutentha, kukana madzi komanso kukana kuvala.Ikhoza kupanga ma coil racks osiyanasiyana, terminal box, nyumba za zida zamagetsi, masamba amakupiza, zomangira pampu za asidi, magiya, makamera, ndi zina zambiri.
