Ukuchaneka kunye nolwalathiso lwe-Mold yeeMveliso ze-PTFE
Intshayelelo: Ngokubanzi, ukuchaneka kwemveliso ye-PTFE akulula ukuyilawula kuba i-coefficient yayo yokwandiswa komgca iphezulu kuneentsimbi, kwaye iqondo layo lokutshintsha umthamo lijikeleze ubushushu begumbi kubangela utshintsho lwevolumu malunga ne-1 ukuya kwi-2%.Ngaphezu koko, i-PTFE enezindonga ezincinci ...Funda ngokugqithisileyo -
Inkqubo yeMveliso ye-PTFE
I-Tetrafluoroethylene yaqala ukulungiswa ngo-1933. I-synthesis yorhwebo yangoku isekelwe kwi-fluorspar, i-sulfuric acid kunye ne-chloroform.Inkqubo yeMveliso eyiSiseko ye-PTFE Polymer: Ukwenziwa kwe-PTFE Polymer/Resin ngokwesiseko kuqhutywa ngokwezigaba ezibini.Okokuqala, i-TFE Monomer isetyenziswa ngokubanzi...Funda ngokugqithisileyo -
Ukukhutshwa kweepolymers
I-Extrusion yinkqubo yokwenziwa kweemveliso ezinde zecandelo elinqamlezayo (iintonga, amashiti, imibhobho, iifilim, ukugquma ngocingo) ukunyanzela ukuthambisa ipolymer ngokufa ngokuvula.Izinto zePolymer ngendlela yeepellets zityiswa kwi-extruder nge-hopper.Isixhobo si...Funda ngokugqithisileyo -
Ipolymer adsorption
I-Adsorption kukunamathela kwee-ion okanye iamolekyu kumphezulu wesinye isigaba.I-Adsorption ingenzeka nge-physisorption kunye ne-chemisorption.Iiyoni kunye neemolekyuli zinokubhengeza kwiintlobo ezininzi zemigangatho ebandakanya umphezulu wepolymer.Ipolymer yimolekyuli enkulu eyenziwe ngamasuntswana aphinda-phindayo adityaniswe kunye...Funda ngokugqithisileyo -
Polycarbonates (PC) vs Polymer PTFE/FEP Machining
I-Polycarbonates (i-PC) liqela leepolima ze-thermoplastic eziqukethe amaqela e-carbonate kwizakhiwo zabo zemichiza.Iipolycarbonates ezisetyenziswa kubunjineli zinamandla, izixhobo eziqinileyo, kwaye amanye amabakala abonakala elubala.Zisebenza ngokulula, zibunjwe, kwaye zenziwe nge-thermoform.Ngenxa yezi zinto...Funda ngokugqithisileyo -
Ukusetyenzwa kunye nokwenza izixhobo zePTFE
I-PTFE yaziwa ngozinzo kunye nokumelana neekhemikhali ezininzi.… Oku kuyenza ibe yimathiriyeli eguquguqukayo kakhulu, kwaye siyayibumba, sibumba kunye namalungu omatshini kule mathiriyeli.Ngokubanzi, i-PTFE icutshungulwa ibe ziimilo ezigqityiweyo ngoxinzelelo okanye ubuchule bokubumba i-iso-static.Inkqubo ye-PTFE...Funda ngokugqithisileyo
