Kutheni ibizwa ngokuba ityhubhu ye-ptfe?Ibizwa njani ptfe ityhubhu?
ityhubhu yePolytetrafluoroethylene ikwabizwa ngokubaPTFE ityhubhu, eyaziwa ngokuba yi "Plastic King", yipolymer ephezulu yemolekyuli elungiselelwe yi-polymerizing tetrafluoroethylene njenge-monomer.I-waxy emhlophe, i-translucent, ubushushu obugqwesileyo kunye nokumelana nokubanda, ingasetyenziswa ixesha elide kwi-180≥260ºC.Lo mbandela awunayo nayiphi na i-pigments okanye i-additives, ineempawu zokuchasana ne-asidi, i-alkali, kunye neentlobo ezahlukeneyo ze-solvents eziphilayo, kwaye ziphantse zinganyibiliki kuzo zonke izinyibilikisi.Kwangaxeshanye, i-PTFE ineempawu zokunganyangeki kobushushu obuphezulu, kwaye i-friction coefficient iphantsi kakhulu, ngoko ingasetyenziselwa ukuthambisa kwaye ibe luyilo olufanelekileyo lokucocwa lula komgangatho wangaphakathi wemibhobho yamanzi.
Indlela yokuvelisa:
Izinto ezikrwada ze-PTFE ityhubhu ngumgubo kwaye zinokubunjwa ngokucinezelwa okanye ukuqhutyelwa kwe-extrusion
Uhlobo lwetyhubhu:
I-1.I-tubing egudileyo yenziwa kwi-virgin 100% ye-PTFE resin ngaphandle kwe-pigment okanye isongezo.Ifanelekile ukusetyenziswa kwi-Aero space & Technology Technology, i-Electronics, i-Components & Insulators, i-Chemical & Pharmaceutical Manufacturing, ukuCwangciswa kokutya, iSayensi yokusiNgqongileyo, iSampulu yoMoya, iZixhobo zokuThuthwa kwe-Fluid kunye neNkqubo yokuLungisa amanzi.I-Anti-static (iKhathoni) okanye iinguqulelo zemibala yazo zonke iityhubhu ziyafumaneka.
I-2.I-tubing edibeneyo yenziwe kwi-virgin 100% ye-PTFE resin ngaphandle kwe-pigment okanye i-additive.Ibonisa ukuguquguquka okugqwesileyo kunye nokuchasana kwe-kink yokusebenza okuphezulu kwizicelo apho i-radius egobileyo egobileyo, ukunyuka koxinzelelo okanye ukuxhathisa kuyadingeka.Ityhubhu edityanisiweyo inokufunyanwa ngamaflare, iiflange, iicuffs, okanye indibaniselwano yeSisombululo seTubing esingaphezulu kwesinye.Iinguqulelo ze-Anti-static (carbon) zazo zonke iityhubhu ziyafumaneka.
I-3.I-Capillary tubing Iimpawu zokushisa kunye nokuxhatshazwa kwe-corrosion yeetyhubhu ze-capillary zisetyenziswe ngokubanzi kumashishini okumelana ne-corrosion, njengeshishini lemichiza, i-pickling, i-electroplating, iyeza, i-anodizing kunye namanye amashishini.Ityhubhu ye-capillary ubukhulu becala inokumelana nokugqwesa okugqwesileyo, ukunganyangeki kakuhle, ukumelana nokuguga okuhle, ukusebenza kakuhle kokuhambisa ubushushu, ukuchasana okuncinci, ubungakanani obuncinci, ubunzima bokukhanya kunye nesakhiwo esibambeneyo.
Iipropati kunye nozinzo:
I-1.Ukumelana nokushisa okuphezulu, okungenakunyibilika kuyo nayiphi na i-solvents.Inokumelana nobushushu obuphezulu ukuya kuma-300℃ ngexesha elifutshane, kwaye ingasetyenziswa ngokuqhubekayo phakathi kwe-240℃ ~ 260℃, kwaye inozinzo olumangalisayo lobushushu.Ukongeza kokuphendula ngesinyithi esinyibilikisiweyo se-alkali, ayigqwaliswanga nayiphi na into, nokuba ibiliswe kwi-hydrofluoric acid, i-aqua regia okanye i-fuming sulfuric acid, i-sodium hydroxide, ayiyi kutshintsha.
I-2.Ukumelana nokushisa okuphantsi, ukuqina kakuhle komatshini kwiqondo lokushisa eliphantsi, nokuba iqondo lokushisa liyehla ukuya kwi -196 ℃ ngaphandle kwe-embrittlement, inokugcina i-5% elongation.
I-3.I-Corrosion resistance, i-inert kuninzi lweekhemikhali kunye ne-solvents, echasene ne-acids eqinile kunye ne-alkalis, amanzi kunye neentlobo ezahlukeneyo ze-solvents eziphilayo, kwaye inokukhusela iinxalenye kulo naluphi na uhlobo lokubola kweekhemikhali.
I-4.I-Anti-aging, phantsi komthwalo ophezulu, ineenzuzo ezimbini zokuxhatshazwa kokugqoka kunye nokungabambeleli.Inobomi bobudala obuhle kwiiplastiki.
I-5.I-lubrication ephezulu, eyona nto iphantsi kwe-friction coefficient phakathi kwezinto eziqinileyo.I-coefficient ye-friction iyatshintsha xa umthwalo uhambisa, kodwa ixabiso liphakathi kwe-0.05-0.15 kuphela.
6. Ukungancamathiseli, okuyiyona nto inoxinzelelo oluncinci lomphezulu phakathi kwezinto eziqinileyo, kwaye ayibambeleli kuyo nayiphi na into.Phantse zonke izinto aziyi kunamathela kuyo.Iifilimu ezibhityileyo kakhulu zikwabonisa iipropathi ezintle ezingabambekiyo.
7.Imhlophe, ayinavumba, ayinancasa, ayinatyhefu, kwaye inert ngokwasemzimbeni.Njengomthambo wegazi owenziweyo kunye nelungu elifakwe emzimbeni ixesha elide, alinakho ukusabela okubi.
8.Ubunzima bokukhanya kunye nokuguquguquka okunamandla.Inokunciphisa kakhulu amandla okusebenza komsebenzisi.
I-9.Iinzuzo ezipheleleyo zale mveliso, ukwenzela ukuba ubomi benkonzo bube ngaphezu kweentlobo ezikhoyo ezahlukeneyo ze-hose ye-steam, ukusetyenziswa kwexesha elide akufuneki ukuba kuthathelwe indawo, ukunciphisa kakhulu iindleko zokusetyenziswa, ukuphucula ukusetyenziswa kakuhle, uqoqosho kunye nokusebenza.
