Intonga ye-PTFEIimpawu:Uluhlu lobushushu bokusetyenziswa lubanzi kakhulu (Celsius ukusuka - 200 degrees ukuya +260 degrees);I-Anti-majority chemical substance's corrosiveness, ngaphandle kwe-fluorides kunye ne-alkalinity moltenmetal; Iimpawu ezigqwesileyo zoomatshini, ukumelana nokwaluphala; Ukumelana nedangatye okugqwesileyo (Iyavumelana ne-ASTM-D635 kunye nenqanaba lovavanyo le-D470), emoyeni ukuba ilawulwe njengesixhobo esinedangatye; Iphantsi kakhulu ukufunxwa kwamanzi……
I-PTFE-polytetrafluoroethylene yafunyanwa nguGqr. Roy Plunkett weDuPont Research Laboratory ngoAprili 6, 1938. I-PTFE yoqobo yaphuhliswa ngakumbi nguDupont yaza yakhutshwa njengemveliso ngo-1945.
Imveliso imelana kakhulu nokonakala kweekhemikhali kwaye inokumelana namaqondo obushushu angaphezu kwama-500 ° C. Enye yezinto zasekhaya zokuqala ze-PTFE yi-“PTFE coated frying pan”.Nangona imbiza isebenza kakuhle kakhulu, yahlukile kwiintonga ze-PTFE kunye neepleyiti esizinikezelayo.Ifafazwe malunga nokwaleka okumnyama, iintonga ezisulungekileyo ze-PTFE kunye neeshiti kwi-PTFE yebha engqukuva ipakethe yevalve yomphunga imhlophe qhwa usetyenziswa njani na kwimizi-mveliso ye-PTFE iintonga zeplastiki zokusebenzisa ii-PTFE iigaskets ze-PTFE kunye nokupakishwa komphunga.
Ngenxa yokuba i-PTFE inobushushu obuphezulu kunye nokumelana neekhemikhali, idla ngokusetyenziselwa usetyenziso lwevalvu.Ukusuka kumphunga olula / iivalvu zamanzi ashushu ukuya kwiqondo lobushushu eliphezulu, ulwelo oluphathwayo kumashishini e-caustic iivalvu zekhemikhali.Esi sixhobo si-semi-rigid ukuya kwiplastiki eqinileyo kwaye inokwenziwa lula - enye yezona zilula ukusebenzisa iplastiki.Intonga ye-PTFE inokwenziwa ngoomatshini ekunyamezelweni okusondele kakhulu kwiintonga ezininzi zedayamitha ezincinci ezinobubanzi be +.002 “/ — .00”.Ukumelana nemichiza yenye yezinto eziphambili ezinxulumene nezixhobo.Kwiiflakes okanye iiflakes, i-PTFE isetyenziswa njengesixhobo se-gasket kubushushu obuphezulu kunye neeflange ezixhathisa iikhemikhali kunye netywina.
