Kutulutsa thovu kwa Fluorocarbon resins

DuPont yapanga ukadaulo wovomerezeka pakuphatikiza ndi kukonza utomoni wa thovu la fluoropolymer.Njira ya thovu imaphatikizapo kubayidwa kosalekeza kwa gasi monga nayitrogeni mwachindunji mu chotulukapo chodzaza ndi utomoni wosungunuka.Chomangira chopangidwa mwapadera cha extruder screw chimagwiritsidwa ntchito kupanga chosakaniza cha gasi wa polima wokhala ndi phukusi la inert nucleating lomwe lili mu utomoni kuti zithandizire kulimbikitsa kukula kwa maselo.Zithovu za 60% voids zawonetsedwa pogwiritsa ntchito njirayi.

Mapulogalamu a Melt Processable Perfluorinated Resins

FEP ndi PFA perfluorinated resins imakhala ndi viscosity yosungunuka yokwanira kuti isungunuke muzitsulo zosungunuka.Kuphatikiza apo, FEP ndi PFA ndizoyenera kuchita thovu lakunja kwinaku akusunga zinthu zawo zotsika kwambiri za dielectric komanso zotsika, zonse zofunika pazingwe zopotoka komanso zolumikizira chingwe cha coaxial.

Zingwe za data zimagwiritsidwa ntchito pofalitsa ma siginecha apakompyuta m'makonzedwe osiyanasiyana ndi ntchito.Zofunikira zamagetsi zomwe zimafunikira pazingwezi zimaphatikizapo kutsika kwa dielectric ndi kutsika kwapang'onopang'ono.Zinthu izi zitha kupitilizidwa ndi kutulutsa thovu pa insulation.Kutengera utomoni womwe umagwiritsidwa ntchito, zingwe zokhala ndi thovu zimalola kuti chingwe chichepetse, kuchepetsa kulemera kwa chinthu chomaliza, komanso kutumiza ma siginecha amagetsi apamwamba kwambiri pa liwiro lalikulu.

Zingwe za thovu zopangidwa kuchokera ku DuPont fluoropolymer resins zatchuka kwambiri pakupanga makompyuta ndi kukhazikitsa makina apakompyuta.Zingwe zopangidwa ndi FEP kapena PFA zimakhala ndi moto wochepa komanso utsi wochepa.Zingwezi zimatha kuyenda kudzera m'ma plenum ndi njira zina zoyendetsera mpweya, zomwe zimachepetsa kufunika koyika njira yamagetsi yokwera mtengo.

Kapangidwe ndi Katundu wa Fluoropolymers

Kupezeka kwa PTFE ndi DuPont kunachitika m'zaka za m'ma 1930, koma panthawiyo, utomoni watsopano wa perfluorinated sungathe kusungunuka.Kafukufuku wowonjezereka wa DuPont pakusintha kamangidwe ka ma polima adapangitsa kuti pakhale ma fluoropolymer angapo osungunuka osungunuka monga FEP, PFA, ndi ETFE, kulimbitsa DuPont ngati mtsogoleri wapadziko lonse pa kafukufuku wa fluoropolymer.

Kutha kusungunula ma polima awa, kuphatikizidwa ndi mawonekedwe monga kutsika kwa dielectric mosakhazikika komanso kutsika pang'ono kumapangitsa FEP ndi PFA kukhala yoyenera kugwiritsa ntchito waya ndi chingwe.
