Kukho iindidi ezimbini zeIipleyiti ze-PTFE: ukubumba kunye nokutyibilika / ukujika.Ipleyiti yokubumba yenziwe nge-polytetrafluoroethylene resin ngokubumba kwiqondo lokushisa, kwaye emva koko i-sintered kwaye ipholile.Ipleyiti yokujika yenziwe nge-PTFE resin ngokucinezela, ukucofa, kunye nokuxobula.

Ipleyiti ye-PTFE ineyona ndlela ibalaseleyo yokuxhathisa ibrasion phakathi kwazo zonke iiplastiki zobunjineli kwaye yeyona itsala amehlo.Ukuphakama kobunzima bemolekyuli, kokukhona i-material engagugiyo, nangaphezulu kwemathiriyeli yentsimbi (efana ne-carbon steel, stainless steel, bronze, njl.njl.).Ngokomzekelo, iipayipi ze-UHMW-pe zinobomi benkonzo ye-4-6 amaxesha eemibhobho zetsimbi phantsi kweemeko ze-corrosion enamandla kunye nokugqoka okuphezulu, kunye nokusebenza kakuhle kokuhanjiswa kwanda ngama-20%.Ibonisa ngokupheleleyo ukongama "kokulondolozwa kwamandla, ukukhuselwa kwendalo, uqoqosho, kunye nokusebenza okuphezulu".
Zeziphi izinto eziluncedo kwipleyiti ye-PTFE?
Ukumelana nobushushu obuphezulu– Ubushushu bokusebenza bunokufikelela kwi-250℃.
Ukumelana nobushushu obuphantsi-Inokuqina kakuhle koomatshini;nokuba iqondo lobushushu liyehla ukuya ku -196℃, inokugcina ubude obuyi-5%.
Ukumelana nokubola- I-inert kuninzi lweekhemikhali kunye ne-solvents, kwaye inokumelana ne-acids eqinile kunye ne-alkalis, amanzi kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.
Ukumelana nemozulu-Inobomi bobudala obuhle phakathi kweeplastiki.
Ukuthambisa okuphezulu-I-coefficient ephantsi ye-friction phakathi kwezinto eziqinileyo.
Ukunganamatheli– Yeyona nto incinci yoxinzelelo kumphezulu phakathi kwezinto eziqinileyo kwaye ayibambeleli kuyo nayiphi na into.I-coefficient ye-friction ye-mechanical properties incinci kakhulu, kuphela i-1/5 ye-polyethylene, eyona nto ibalulekileyo kwi-perfluorocarbon surface.Ukongeza, ngenxa yokuba i-fluorine-carbon chain intermolecular forces iphantsi kakhulu, i-PTFE ayincangathi.
Ayinatyhefu-Ngokungasebenzi komzimba, ukufakelwa kwexesha elide kwemithambo yegazi eyenziweyo kunye namalungu emzimbeni ngaphandle kokuphendula kakubi.
Uluhlu lwesicelo se-PTFE plate lulandelayo:
1. Isebenzisa iimpawu ze-friction coefficient ephantsi, isetyenziselwa ukombiwa kwe-oyile kwi-offshore iderrick slide veneer, i-dock slide veneer, isango lomlambo isango le-slide veneer, ibhulorho ye-telescopic yokuxhasa isilayidi veneer, izixhobo ezahlukeneyo zoomatshini, oomatshini abadikayo, igrinder, iplaner sliding guideer. , njl.
2. Ukusebenzisa iipropathi zayo ezingeyontonga, isetyenziswa kwishishini leswekile, kwishishini lempahla, ukutya, kunye nebhanti yokuhambisa yokubhaka icuba, ukuprinta, kunye neshishini lokudaya i-anti-sticking anti-corrosion coating layer ye-roller ezahlukeneyo zesikhokelo, njl.
3. Ukusetyenziswa kweenjini ze-dielectric zisebenza kakuhle kakhulu kwaye zisetyenziselwa izikhululo zamandla ezishisayo, iiseli ze-electrolytic, izindandatho zokutywina, iisekethe eziprintiweyo kwizixhobo ze-elektroniki kunye namashishini ekhompyutheni yekhompyutha, i-copper-clad substrates, i-cutting-edge eyahlukeneyo kunye nezixhobo ezikhethekileyo.
4. Ukuthatha ithuba lokuzinza kwayo kakuhle kwikhemikhali, ingasetyenziselwa ikakhulu kwi-gaskets, linings, i-valve discs, kunye ne-diaphragms yeevalvu ezinkulu kwi-petroleum, ikhemikhali, kunye namashishini ekhemikhali, kunye ne-linings yemikhumbi eyahlukeneyo yokusabela, iitanki zokugcina. , kunye neenqaba zokusabela, ipleyiti yokuhambisa, njl.
Ukusetyenziswa kwepleyiti yePTFE elungisiweyo
Ipleyiti yePTFE elungisiweyoyimathiriyeli ekhethwayo yolwembu olungagugiyo, ngoko ke zithini iindawo zesicelo sepleyiti yePTFE elungisiweyo?
Njengezinto zokutywina, iipleyiti ze-PTFE ezilungisiweyo zisetyenziswa kakhulu koomatshini, i-petrochemical, izithuthi, i-textile, kunye namashishini okwakha.Ngokutsho irhasi ekhethiweyo permeability ipleyiti PTFE emva unyango, ingasetyenziswa njengento yokwahlula ngokukhetha ukungena igesi okanye ulwelo, ingakumbi ukuhluza ulwelo ezonakalisayo.Kwiminyaka yakutshanje, ipleyiti ye-PTFE elungisiweyo isetyenziswe njengelungu lokwenziwa, kwaye iya kusetyenziswa kwiinkalo ezahlukeneyo kwixesha elizayo, elinethemba lophuhliso oluhle.
