Umgangatho ophezulu wentsimbi ye-PTFE yofakelo lwemibhobho enemigca

Izixhobo zombhobho owenziwe ngeTeflon ziyintsimbi ye-PTFE yodidi lwemibhobho edityanisiweyo, enokumelana ne-asidi eyomeleleyo kunye nealkali.
Intshayelelo yombhobho: I-PTFE efakwe kwimibhobho yokufakelwa kwe-anti-corrosion emva kweminyaka yokusetyenziswa kokwenene, ichaphazela ngqo ubomi bayo benkonzo kunye nezinto ezizinzileyo zokusebenza zibubushushu, uxinzelelo, imidiya, njl., izinto ezigqwesileyo kunye nenkqubo yokuvelisa inqanaba eliphezulu lokuqinisekisa umgangatho weemveliso ze-PTFE ezinemigca.
Iimbonakalo
1. Ubushushu obuphezulu kwimithombo yeendaba eyomeleleyo, inokuhlangabezana nokusetyenziswa koluhlu lweqondo lobushushu -60 degrees ~ 200 degrees, kolu luhlu lweqondo lobushushu linokudibana nayo yonke imidiya yeekhemikhali.
2. Ukuxhatshazwa kwe-vacuum kungasetyenziselwa phantsi kweemeko ze-vacuum, kwimveliso yeekhemikhali, ngokuphindaphindiweyo ngenxa yokupholisa, ukukhutshwa kwe-longitudinal, i-valve yepompo ayihambelani nokusebenza kwemeko ebangelwa yi-vacuum state yendawo.
3. Ukuxhatshazwa koxinzelelo oluphezulu ekusetyenzisweni kweqondo lokushisa, kunokumelana ne-3MPA yokusetyenziswa koxinzelelo
4. Ukusetyenziswa kwe-Anti-permeation ye-resin ye-PTFE egqwesileyo, ngokusebenzisa inkqubo ye-lining ephezulu ibe yi-high density, ubukhulu obaneleyo be-PTFE ye-lining layer, ukwenzela ukuba imveliso ibe ne-anti-permeability ephezulu.
5. Inkqubo yonke yokubumba kunye ne-sintering ye-lining isombulula ingxaki yokwandiswa okushushu kunye nokubandayo kwentsimbi kunye ne-fluorine, okwenza ukuba kufezekiseke ukwandiswa kwe-synchronous
6. Imilinganiselo esemgangathweni iyamkelwa, ngokukodwa kwimibhobho kunye nezixhobo ezisetyenziselwa kwiipayipi zekhemikhali, ezitshintshisana kakhulu kwaye zibonelela ngokulula okukhulu kokufakela kunye neendawo zokuncedisa.
Iinzuzo zokunqanda ukubola:
1. Ukumelana nobushushu obuphezulu {sebenzisa ubushushu be-260 degrees.
2. I-asidi eyomeleleyo kunye nokumelana ne-alkali (pH 1 ~ 14)
3. Ukubambelela okugqwesileyo {uxinzelelo olubi lunokufikelela kwi-0.09MPa, umphumo we-vacuum.
4. Ubomi benkonzo ende {Phantsi kweemeko eziqhelekileyo zingasetyenziselwa iminyaka eyi-8 ukuya kwe-10, kwaye ixesha lewaranti lithenjiswe ngokubanzi ukuba libe ngunyaka we-1.
5. Ukuchasana okunamandla ekungeneni {hydrofluoric acid.Irhasi yeklorini.I-Bromofluoric acid kunye nezinye iigesi zinokuxhathisa okulungileyo ekungeneni
Ukusebenza:
Ukusebenza: umsebenzi ophakathi -100℃~-250℃
Uxinzelelo oluphakathi lokusebenza: uxinzelelo oluhle: -2.5MPa, ukuxhathisa uxinzelelo olubi kwiqondo lokushisa 70KPa
Ukumelana nokubola: insimbi ye-polytetrafluoroethylene yeklasi yofakelo lwemibhobho edibeneyo, ukongeza kwi-lithium yesinyithi etyhidiweyo, i-potassium, i-sodium, i-chlorine trifluoride, i-oxygen trifluoride kubushushu obuphezulu, izinga lokuhamba okuphezulu kwe-fluorine yolwelo, inokuxhathisa phantse yonke imithombo yeendaba zemichiza, kubandakanywa ne-nitric acid kunye I-aqua regia corrosion, inokusebenza kwi-230 ℃ - 250 ℃ yobushushu ixesha elide.Iklasi ye-Steel polyvinylidene fluoride okanye enye i-vinylidene fluoride class composite tube, ukuya kwi-halogen, i-halogenated hydrocarbons, i-oxidants eyomeleleyo, i-asidi ebilayo, i-alkali, iindidi ze-solvents eziphilayo zinokuxhathisa okulungileyo kokuhlwa, kodwa kungekhona ukuvutha kwe-asidi ye-sulfuric, i-acid eshushu ye-sulfuric kunye ne-nitric acid, I-90 ℃ ngaphezu kwe-ketone, i-ester, i-amine kunye nobushushu obuphezulu be-agent corrosion.
Izinto eziluncedo:
Ukumelana nobushushu obuphezulu - sebenzisa ubushushu bokusebenza ukuya kuthi ga kwi-250 ℃.
Ukumelana nokushisa okuphantsi - ukuqina okulungileyo komatshini;nokuba iqondo lokushisa liyehla ukuya kwi-196 ° C, ubude bunokugcinwa kwi-5%.
Ukumelana ne-Corrosion - inert kuninzi lweekhemikhali kunye ne-solvents, ukumelana ne-acids eqinile kunye ne-alkalis, amanzi kunye neentlobo ezahlukeneyo ze-solvents eziphilayo.
Ukumelana nemozulu - inobomi bokuguga obungcono kunayo nayiphi na iplastiki.
I-lubricious ephezulu - i-coefficient ephantsi ye-friction yayo nayiphi na into eqinileyo.
I-Non-adhesive - ine-tension yomhlaba ephantsi kwayo nayiphi na into eqinileyo kwaye ayihambelani nayo nayiphi na into.
Ayinatyhefu - ayinayo ityhefu kwizinto eziphilayo
Ukusetyenziswa kwemveliso:
Steel lined PTFE izicelo zofakelo lombhobho: zilungele iigesi ezigqwalisayo kakhulu kunye nolwelo kumaqondo obushushu aphezulu, ezinye iindidi zentsimbi-yeplastiki imibhobho composite kunye nemibhobho yentsimbi ayifanelekanga ukuthutha eendaba, intsimbi PTFE composite.Umbhobho odibeneyo uyasebenza, insimbi ye-polyvinylidene fluoride iklasi yombhobho edibeneyo ilungele ukuthuthwa kweendaba ezidliwayo kwiqondo lokushisa elisebenzayo -40 ℃ ~ +150 ℃.
Intsimbi efakwe kwi-PTFE yofakelo lwemibhobho ehlanganisiweyo, kusetyenziswa inkqubo yokwenyani eqinileyo, ukumelana noxinzelelo olubi kunye ne-vacuum, ukubumba ngaphandle kwemithungo, kucaba kwaye kuqinile, akukho mphezulu weconcave.Indibaniselwano ayiwi.Isetyenziswa kakhulu kumandla ombane, ishishini lemichiza, iimveliso zepetrochemical, ukukhuselwa kwendalo kunye namanye amashishini.
