Ikhwalithi ephezulu yensimbi ye-PTFE yokufakwa kwamapayipi anemigqa

Ukufakwa kwamapayipi afakwe ulayini we-Teflon kuwuhlobo lwensimbi eyinhlanganisela ye-PTFE yokufakwa kwamapayipi, engamelana ne-asidi eqinile ne-alkali.
Isingeniso sepayipi: Ukufakwa kwamapayipi okulwa nokugqwala kwe-PTFE ngemuva kweminyaka yokusetshenziswa kwangempela, kuthinta ngqo impilo yayo yesevisi kanye nezici zokusebenza ezizinzile izinga lokushisa, ingcindezi, imidiya, njll., izinto ezinhle kakhulu kanye nenqubo yokukhiqiza ethuthukisiwe isiqinisekiso sekhwalithi yemikhiqizo efakwe umugqa ye-PTFE.
Izici
1. Izinga lokushisa eliphezulu emithonjeni eqinile egqwalayo, lingahlangabezana nokusetshenziswa kwezinga lokushisa -60 degrees ~ 200 degrees, kuleli banga lokushisa lingahlangabezana nayo yonke imidiya yamakhemikhali
2. Ukumelana ne-vacuum kungasetshenziswa ngaphansi kwezimo ze-vacuum, ekukhiqizeni amakhemikhali, ngokuvamile ngenxa yokupholisa, ukukhishwa kwe-longitudinal, i-valve yepompo ayivumelaniswa nokusebenza kwesimo esibangelwa isimo se-vacuum sendawo.
3. Ukumelana nokucindezela okuphezulu ekusetshenzisweni kwebanga lokushisa, kungamelana no-3MPA wokusetshenziswa kwengcindezi
4. Ukusetshenziswa kwe-Anti-permeation kwe-resin ye-PTFE enhle kakhulu, ngenqubo ye-lining ethuthukisiwe ibe ukuminyana okuphezulu, ukushuba okwanele kwesendlalelo se-PTFE, ukuze umkhiqizo ube nokuphikisana okuphezulu.
5. Inqubo yonke yokubumba kanye ne-sintering ye-lining ixazulula inkinga yokwanda okushisayo nokubandayo kwensimbi ne-fluorine, okwenza kufinyelele ukunwetshwa okuvumelanayo.
6. Ubukhulu obujwayelekile buyamukelwa, ikakhulukazi amapayipi nokufakwa okusetshenziselwa amapayipi amakhemikhali, aguquguqukayo kakhulu futhi anikeze ukukhululeka okukhulu kokufakwa kanye nezingxenye ezisele.
Izinzuzo ze-anti-corrosion:
1. Ukumelana nezinga lokushisa eliphezulu {sebenzisa izinga lokushisa elingu-260 degrees.
2. I-asidi eqinile kanye nokumelana ne-alkali (pH 1~14)
3. Ukunamathela okuhle kakhulu {ingcindezi engalungile ingafinyelela ku-0.09MPa, umphumela we-vacuum.
4. Impilo ende yesevisi {Ngaphansi kwezimo ezijwayelekile ingasetshenziswa iminyaka engu-8 kuya kwengu-10, futhi isikhathi sewaranti ngokuvamile sithenjiswa ukuthi singunyaka ongu-1.
5. Ukumelana okuqinile nokungena {hydrofluoric acid. Igesi ye-chlorine. I-Bromofluoric acid namanye amagesi anokumelana okuhle nokungena
Ukusebenza:
Ukusebenza: umsebenzi ophakathi -100℃~-250℃
Ingcindezi yokusebenza emaphakathi: ingcindezi enhle: -2.5MPa, ukumelana nengcindezi engafanele ekamelweni lokushisa 70KPa
Ukumelana nokugqwala: ukufakwa kwepayipi eliyinhlanganisela yensimbi ye-polytetrafluoroethylene, ngaphezu kwensimbi encibilikisiwe ye-lithium, i-potassium, i-sodium, i-chlorine trifluoride, i-oxygen trifluoride emazingeni okushisa aphezulu, izinga lokugeleza okuphezulu kwe-fluorine ewuketshezi, ingamelana cishe nayo yonke imidiya yamakhemikhali, kufaka phakathi ukugqwala kwe-nitric acid ne-aqua regia corrosion, ingasebenza ku-2 ℃ 2 ℃ 2 ℃ ℃ 2 ℃ ℃ isikhathi. Ikilasi lensimbi le-polyvinylidene fluoride noma elinye ishubhu eliyinhlanganisela yekilasi le-vinylidene fluoride, kuya ku-halogen, ama-halogenated hydrocarbons, ama-oxidants aqinile, i-asidi ebilayo, i-alkali, izinhlobonhlobo zezinyibilikisi eziphilayo zinokumelana nokugqwala okuhle, kodwa hhayi ukufutheka kwe-sulfuric acid, kugxilwe sulfuric acid eshisayo kanye ne-nitric acid, i-aminetone ℃ ngaphezu kwe-90 sulfuric acid, i-aminetone ℃ ngaphezu kwe-90 ℃ ukugqwala kwe-agent.
Izinzuzo:
Ukumelana nokushisa okuphezulu - sebenzisa izinga lokushisa elisebenzayo elifika ku-250 ℃.
Ukumelana nokushisa okuphansi - ukuqina okuhle kwemishini; ngisho noma izinga lokushisa lehla liye ku-196 ° C, ukuphakama kungagcinwa ku-5%.
Ukumelana nokugqwala - ukungena kumakhemikhali amaningi nezincibilikisi, amelana nama-asidi aqinile nama-alkali, amanzi kanye nezincibilikisi ezihlukahlukene eziphilayo.
Ukumelana nesimo sezulu - kunempilo engcono kakhulu yokuguga kunanoma iyiphi ipulasitiki.
I-lubricious kakhulu - i-coefficient ephansi yokungqubuzana kwanoma iyiphi into eqinile.
Okunganamatheli - kunokuqina okuphansi komhlaba kwanoma iyiphi into eqinile futhi akunamatheli kunoma iyiphi into.
Non-toxic - non-toxic ezilwaneni
Ukusetshenziswa komkhiqizo:
Steel lined PTFE ipayipi nokufakwa izicelo: ezifanele amagesi egqwala kakhulu kanye noketshezi emazingeni okushisa aphezulu, ezinye izinhlobo steel-plastic esiyinhlanganisela amapayipi namapayipi ensimbi akufanelekile ukuthutha abezindaba, steel PTFE esiyinhlanganisela. Amapayipi ahlanganisiwe ayasebenza, ipayipi lensimbi le-polyvinylidene fluoride class composite lifanele ukuthuthwa kwemidiya egqwalayo ezingeni lokushisa elisebenzayo elingu -40 ℃ ~ +150 ℃.
Ukufakwa kwepayipi eliyinhlanganisela ye-PTFE okufakwe ulayini wensimbi, kusetshenziswa inqubo eyiqiniso yolayini obuqinile, imelana nengcindezi engemihle kanye ne-vacuum, ukubumba ngaphandle kwemithungo, okuyisicaba futhi okuqinile, akukho ndawo eqondile. Inhlanganisela ayiwi. Isetshenziswa kakhulu emandleni kagesi, embonini yamakhemikhali, emikhiqizweni ye-petrochemical, ukuvikelwa kwemvelo nezinye izimboni.
