Chii chinonzi ptfe lined hose | BESTEFLON

Mumakore achangopfuura, polytetrafluoroethylene (Teflon) rudzi rwezvigadzirwa zvinodzivirira kusvibiswa uye zvinodzivirira kusvibiswa kwemagetsi emagetsi neindasitiri yepetrochemical. Zvisinei, matambudziko anotevera anofanira kutariswa zvakanyanya kanaPTFE yakaputirwapombitambo yacho yakasungirirwa, zvikasadaro hupenyu hwebasa uye kuchengetedzeka kwepombi yePTFE zvichakanganiswa.

1. Pakuchenesa chigadziko chekubatanidza, zvinorambidzwa zvachose kukuvadza simbi yesimbi. Zvinorambidzwa kurova arc pasimbi yesimbi panguva yekusanganisa.

2. Muchikamu che fillet weld, kureba kwe fillet weld kunofanira kupfuura 5mm, kona yeprojekti inofanira kuva yakakura kupfuura kana yakaenzana ne3mm, uye kona yemukati inofanira kuva yakakura kupfuura kana yakaenzana ne10mm.

3. Pakusanganisa goko repombi yakapetwa nePTFE, zviri nani kushandisa nzira yekusanganisa mativi maviri. Izvi zvinoda hunyanzvi hwevashandi vedu, weld inofanira kunge yakati sandara (yakapfava kana yakapfava), isina maburi, welding seam uye slag inclusion phenomenon, uye kukwirira kweweld hakufanirwe kupfuura 2mm. Mushure mekusanganisa, spatter inokonzerwa nekusanganisa inofanira kubviswa zvachose.

4. Kubatanidza kunoenderera mberi kunofanirwa kushandiswa mukusanganisa pombi yePTFE, uye musono wekunamatira haufanirwe kuva nemakatsemuka kana kuchekwa kusingagumi. Kutsvaga Kwakafanana:Hosipa yePTFE yakarukwa, Hosipaipi yakakombama yePTFE

Polytetrafluoroethylene (PTFE) ndeimwe yemazita anonyanya kushandiswa epolytetrafluoroethylene. Hosipaipi yePTFE inoshandiswa muhosipaipi yesimbi isingatsvi, saka hupenyu hwehosipaipi hwakareba kupfuura hosipaipi yerabha kana hosipaipi yerabha yakaputirwa nesimbi isingatsvi. Ine mabhenefiti akawanda kupfuura zvigadzirwa zverabha.

Kirasi I: PTFE yakatwasuka mapaipi uye pombi fittings

Inowanzozivikanwa sepaipi ye liner yakavhurika. Mukuita uku, PTFE inoshandiswa kutenderedza bhaa. Yakakodzera mapaipi ekufambisa ane kumanikidzwa kwakajairika uye akanaka (senge mapaipi matatu ekurapa marara, nezvimwewo), uye haifanirwe kushandiswa papaipi ine mutoro (senge pombi inopinza nekubuda uye mapaipi anogona kuburitsa kumanikidzwa kwakaipa nekudonha kana kutonhodza kamwe kamwe).

Dhayamita dhayamita: dn25-500mm

Tembiricha yebasa: - 40-180oc

Kumanikidzwa kwebasa: 1.6Mpa

Kirasi II: PTFE tight lined straight pipe uye pombi fittings

Inozivikanwa sepombi yesimbi yakaputirwa nesimbi.

Maitiro ekugadzira: Chekutanga, zvidimbu zvakati wandei zvefirimu rePTFE zvinoputirwa pachiumbwa, wobva waya yesimbi (Ø 0.5-1mm) inoputirwa nespiral pafirimu rePTFE, uye zvidimbu zvakati wandei zvefirimu rakatetepa rePTFE zvinoputirwa kunze kwewaya yesimbi, uye pakupedzisira zvinoputirwa muchoto kuti zviumbwe. Rusvingo rwemukati rwepombi yakagadzirwa nePTFE rwakagadzirwa nenzira iyi rwakatsetseka, uye rusvingo rwekunze rwakagadzirwa nespiral corrugated nekuda kwehuwandu uye simba re elastic rewaya yesimbi.

Nzvimbo iri pakati pemadziro ekunze epaipi yakafukidzwa nePTFE nemadziro emukati epaipi yesimbi inozadzwa neresin (isina mweya wakasara). Resin yekuzadza inogona kusungirirwa zvakasimba papombi yesimbi. Panguva imwe chete, inogona kuputirwa zvakasimba pamadziro ekunze ePTFE liner. Mushure mekugadzika kweresin yakazadzwa, ripple yespiral inoumbwa iyo inovharwa neripple yekunze yemadziro eriner. Chimiro ichi chakafanana nekusanganiswa kwenati nebhoti. Kune rumwe rutivi, inogona kudzikamisa uye kutsiva kuwedzera kwekupisa uye kutonhora kwePTFE lining; kune rumwe rutivi, kuomarara kwewaya yesimbi kunogona kuvandudza zvakanyanya kuramba kwePTFE lining.

Dhayamita yekutsanangurwa: dn25-200 mm

Kushanda tembiricha: - 50-180oc

Kushanda kumanikidzwa: 0.5-1.6mpa

Rudzi rwechitatu: PTFE push (presseze) pombi yakanyatsoiswa pombi yakatwasuka

Inozivikanwa se "push (squeeze) lined straight pipe", inoshandiswa zvakanyanya munyika dzakabudirira muma1990.

Maitiro ekugadzira: Chekutanga, upfu hwePTFE hunopinzwa hunoshandiswa kusunda (kuburitsa) pombi, uye wobva wamanikidzwa kupinda mupombi yesimbi isina musono (dhayamita yekunze ye liner yakakura zvishoma kupfuura dhayamita yemukati yepombi yesimbi ne 1.5-2mm) kuti igadzire jira rakamanikana risina musono. Kuti ibvise kumanikidzwa, inoiswa muchoto yodziiswa kusvika 180oC kuti igadziriswe tembiricha nguva dzose, kuitira kuti ikwanise kushandiswa mutembiricha iri pasi pe 180oC. Panguva imwe chete, sunda (dzvinya) shaft yepombi

Simba rekudhonza riri nani pane repaipi rinopinza tambo. Paipi iyi inodzivirira zvakakwana kumanikidzwa kwakanaka uye kusina kunaka.

Musiyano uripo pakati pePTFE lining nerabha lining

Kuisa tetrafluoroethylene mumupendero kunoshandiswa nekudzivirira ngura kwefluorine, kudzivirira kupisa kwakanyanya, kudzivirira acid nealkali zvakanyanya, kunamira kwakanaka, kugara kwenguva refu uye kudzivirira kupinda kwakasimba. Kupfapfaidza tetrafluoroethylene yese ibasa repamusoro-soro, maitiro ayo anofamba sei? 1. Usati wapfapfaidza, pamusoro payo panofanira kupiswa nejecha uye kupwanywa, uye jira reprimer rakakosha rinopfapfaidzwa. 2. Ipapo upfu hwefluoroplastic hunochajwa nemidziyo yemagetsi ine voltage yakawanda, uye hunonamirwa zvakaenzana pamusoro pechinhu chebasa pasi pesimba remagetsi. 3. Mushure mekubheka pakupisa kwakanyanya, zvidimbu zveclinker zvinonyunguduka kuita jira rekudzivirira rakakora, iro rakabatanidzwa zvakasimba pamusoro pechinhu chebasa. Semuenzaniso, firimu rekufukidza rine ukobvu hwe1 mm rinofanirawo kupfapfaidzwa uye kubikwa kakawanda ka5-6. Kazhinji, ukobvu hwepamusoro hunogona kupfapfaidzwa kusvika 2mm. PTFE lining itekinoroji inoshandiswa zvakanyanya pari zvino. Inoshandisa zvizere fluorine inodzivirira ngura, kuchena kwakanyanya, kuchena, kusanamatira, kusanyorova, kuzvizora, kusapfeka, kupisa kwakanyanya uye kwakaderera, kuputira, nezvimwewo. Mukugadzira, voltage yayo nemagetsi zvinogara zvichigadziriswa kuti zvienderane nemamiriro akakodzera kuti zviwane mhedzisiro yekuputira. Rubber lining inonziwo rubber lining. Inofanira kunamira ndiro yerabha yakagadzirwa pamusoro pesimbi nechinamira kuti iparadzanise ngura kubva kusimbi matrix nechinangwa chekudzivirira. Rabha yechisikigo uye rabha yekugadzira zvinoshandiswa pakuisana. Rubber yakawanda inoshandiswa mukuisana kwemidziyo yemakemikari irabha yechisikigo. Chikamu chikuru cherabha yechisikigo ipolymer yeisoprene, iyo inoputirwa nekuwedzera sarufa. Rabha yakaputirwa ine simba rekupisa uye simba remakanika. Inogona kukamurwa kuita rabha yakapfava, rabha yakaoma uye rabha yakaoma mhando nhatu. Rabha yakaoma ine simba rekudzivirira ngura, kuramba kukwegura uye simba rakasimba rekubatanidza nesimbi. Rabha yakapfava ine simba rekudzivirira kutonhora, kuramba kupisa uye kuramba kukanganiswa, uye ine simba rakati; rabha yakaoma iri pakati pezviviri. Pamusoro pema oxidants akasimba uye zvimwe zvinonyungudutsa, rabha rakaoma rinogona kuramba ngura yema inorganic acids akawanda, organic acids, alkalis, munyu uye alcohols. Nokudaro, rabha rakaoma rinoshandiswa sechinhu chikuru chinodzivirira ngura chisiri chesimbi. Rabha rakavhurika rinogona kukamurwa kuita rabha rakavhurika, rabha rinopisa rinodziya nemhepo yakajairika, rabha rakavhurika uye rabha rakavhurika rechisikigo. Rabha rakavhurika rinoshandiswa mumidziyo mikuru yekubika.
