Fotokozani kusiyana pakati pa epoxy glass fiber board ndi PTFE board mwatsatanetsatane

Lero, Ndikufuna kugawana nanu kusiyana pakati pa epoxy glass fiber board ndi PTFE board, ndiye tiyeni tiwone pamodzi.

Choyamba, tiyenera kudziwa zomwe epoxy glass fiber board ndi PTFE board ndi.

PTFE mbale anawagawa m’magulu awiri: mbale kuumbidwa ndi anatembenuza mbale. Ma mbale opangidwawo amapangidwa ndi utomoni wa polytetrafluoroethylene pomanga kutentha kwa firiji, kenako amawotcha ndikukhazikika. Bolodi yotembenuza imapangidwa ndi utomoni wa PTFE pokanikiza, kupukuta, ndi kusenda. Pali mitundu iwiri ya mbale PTFE: mbale kuumbidwa ndi anatembenuza mbale. Mambale opangidwa amapangidwa ndi utomoni wa polytetrafluoroethylene powaumba pa kutentha kwa firiji, kenako amawotcha ndikukhazikika. Bolodi yotembenuza imapangidwa ndi utomoni wa PTFE pokanikiza, kupukuta, ndi kusenda. High kutentha kukana mpaka 250 ℃, otsika kutentha kukana -196 ℃, kukana dzimbiri, kukana nyengo, kondomu mkulu, sanali adhesion ndi makhalidwe ena. Kupatula chitsulo chosungunula cha alkali, mbale ya PTFE simawononga konse ndi ma reagents amankhwala. Mwachitsanzo, mu sulfuric acid, nitric acid, hydrochloric acid, kapena ngakhale yophika mu aqua regia, kulemera kwake ndi ntchito zake sizisintha, ndipo pafupifupi insoluble mu zosungunulira zonse.

Epoxy galasi CHIKWANGWANI bolodi amatchedwanso epoxy galasi CHIKWANGWANI bolodi, epoxy phenolic laminated galasi nsalu bolodi, epoxy utomoni amatanthauza organic polima pawiri munali magulu awiri kapena kuposa epoxy mu molekyulu. Wachibale maselo misa wa si mkulu. Mapangidwe a maselo a epoxy resin amadziwika ndi gulu logwira ntchito la epoxy mu unyolo wa maselo. Gulu la epoxy likhoza kupezeka kumapeto, pakati kapena mumayendedwe ozungulira a unyolo wa maselo. Chifukwa mamolekyuwa ali ndi magulu a epoxy omwe amagwira ntchito, amatha kukumana ndi mitundu yosiyanasiyana ya machiritso kuti apange ma polima osasungunuka komanso osasunthika okhala ndi maukonde anjira zitatu.

Ndiye pali kusiyana kotani pakati pa epoxy glass fiber board ndi PTFE board?

Gulu la PTFE limapangidwa ndi utomoni wa polytetrafluoroethylene kudzera munjira yapadera monga kuumba, kuthamanga kwa hydraulic, kutembenuka, etc. Ntchito yake imatha kupirira kutentha kwa madigiri 260. Gulu la epoxy glass fiber board limapangidwa ndi ulusi wagalasi womwe umayikidwa ndi guluu wa epoxy resin ndi wochiritsa. , Kutentha kwa kutentha kumakhala pafupifupi madigiri 100, bolodi la PTFE limatha kupirira asidi ndi alkali iliyonse, ndipo epoxy imawopa asidi amphamvu. Kuchokera pamalingaliro amagulu apulasitiki, akale ndi a pulasitiki ya thermoplastic, ndipo yotsirizirayi ndi ya pulasitiki ya thermosetting. The epoxy glass fiber board ili ndi mphamvu zambiri kutentha.
