Mbiri yachitukuko cha epoxy glass fiber drawing rod ingafune kuyang’ana izi.

Epoxy galasi CHIKWANGWANI kujambula ndodo amapangidwa ndi ulusi wamphamvu kwambiri wa aramid ndi ulusi wagalasi womwe umayikidwa ndi epoxy resin matrix ndi kutentha kwambiri kwa pultrusion. Ili ndi mawonekedwe amphamvu kwambiri, kukana kwamphamvu kwambiri, kukana kwa asidi ndi alkali, kukana kwa dzimbiri ndi zina zabwino kwambiri zokana kutentha. Zamgululi ndi oyenera zomera electrolytic zotayidwa, zomera zitsulo, mkulu-kutentha zitsulo zipangizo, UHV zida zamagetsi, minda Azamlengalenga, thiransifoma, capacitors, riyakitala, masiwichi mkulu-voltage ndi zina mkulu-voteji zipangizo zamagetsi.

Kumayambiriro kwa 1872, katswiri wa zamankhwala wa ku Germany A.Bayer anapeza kuti phenol ndi formaldehyde zimatha kupanga mwamsanga zofiira zofiira-bulauni kapena zinthu zowoneka bwino zikatenthedwa ndi acidic, koma kuyesako kunayimitsidwa chifukwa sakanatha kuyeretsedwa ndi njira zakale. Pambuyo pa zaka za m’ma 20, phenol yapezedwa mochuluka kuchokera ku phula la malasha, ndipo formaldehyde imapangidwanso mochuluka monga chosungira. Choncho, zimene mankhwala awiriwa ndi wokongola kwambiri. Tikukhulupirira kuti zinthu zothandiza zitha kupangidwa, ngakhale kuti anthu ambiri agwiritsa ntchito ndalama zambiri. , Koma palibe m’modzi wa iwo amene adapeza zotsatira zomwe zikuyembekezeka.

Mu 1904, Baekeland ndi omuthandizira ake adachitanso kafukufukuyu. Cholinga choyamba chinali kupanga vanishi woteteza m’malo mwa utomoni wachilengedwe. Pambuyo pa zaka zitatu zogwira ntchito mwakhama, pamapeto pake m’chilimwe cha 1907, varnishi yotetezera yokha inapangidwa. Komanso kupanga weniweni kupanga zinthu pulasitiki – Bakelite, odziwika bwino “bakelite”, “bakelite” kapena phenolic utomoni.

Bakelite atatuluka, opanga adazindikira posakhalitsa kuti sangangopanga zinthu zosiyanasiyana zotchinjiriza magetsi, komanso kupanga zofunikira zatsiku ndi tsiku. Edison (T. Edison) ankakonda kupanga zolemba, ndipo posakhalitsa analengeza mu malonda: Zapanga zikwi za zinthu ndi Bakelite. Zogulitsa zotere, kotero kupangidwa kwa Baekeland kudatamandidwa ngati “alchemy” yazaka za zana la 20.

Katswiri wa zamankhwala wa ku Germany Beyer nayenso anathandiza kwambiri pakugwiritsa ntchito bakelite.

Tsiku lina mu 1905, katswiri wa zamankhwala wa ku Germany Beyer anayesa phenol ndi formaldehyde mu botolo, ndipo anapeza kuti mu botolo munapanga chinthu chomata. Anachitsuka ndi madzi ndipo sanathe kuchitsuka. M’malo mwake, adagwiritsa ntchito mafuta, mowa ndi mankhwala ena achilengedwe. Zosungunulira, sizikugwirabe ntchito. Izi zinapangitsa kuti ubongo wa Beyere ukhale wovuta. Pambuyo pake, iye anayesa zonse zimene akanatha kuti achotse “chokwiyitsa” chimenechi. Beyere anapumira mtima n’kukaponya m’mbiya ya zinyalala. mkati.

Patangopita masiku ochepa, Beyere anali atatsala pang’ono kutaya zomwe zili m’nkhokwe ya zinyalala. Panthawiyi, adawonanso chidutswacho. Pamwamba pake panali posalala komanso chonyezimira, komanso kuwala kokongola. Beyere adachitulutsa mwachidwi. Atawotchedwa pamoto, sichinafewenso, chinagwa pansi, sichinasweka, chinachiwona ndi macheka, chinadulidwa bwino, ndipo Beyer wanzeru nthawi yomweyo anaganiza kuti ichi chikhoza kukhala chinthu chabwino kwambiri chatsopano. .
