Qhov zoo ntawm 0-Nplhaib BOX
Thaum qee qhov ntawm 0-ntiv nplhaib ploj lawm, thiab qhov ntsuas qhov ntsuas tau paub thaum cov khoom tsis muaj, 0-ntiv nplhaib cov khoom siv qhov ntev vim tias lawv muab cov kev xaiv ntawm cov sib txuas thiab O-ring qhov ntau thiab tsawg rau kev siv sib txawv.
Cov khoom siv 0-ntiv nplhaib yog ua los ntawm cov khoom siv zoo thiab ruaj khov nitrile roj hmab 0-ings. Cov rings tau zoo nyob rau hauv lub thawv kom ruaj ntseg cia.
Cov khoom siv 0-ntiv nplhaib yog cov qauv kev lag luam, thiab lawv muaj cov npog sab nraud, uas muaj cov ntsiab lus ntawm qhov ntau, thiab qhov ntau thiab tsawg ntawm tag nrho 0-ntiv nplhaib ntsaws ruaj ruaj hauv txhua qhov chaw.
0-ntiv nplhaib cov khoom siv tau muab rau hauv cov roj hmab nitrile vim tias feem ntau cov neeg siv khoom siv hauv cov dej ntsev, cov ozone pab lawv tawm tsam NBR. Yog li ntawd, Viton thiab NBR oring lub thawv tau siv tes hauv tes los rhuav tshem cov nitrile hardness.
Viton oring lub thawv yog qhov tseem ceeb hauv kev kho faucets vim yog NBR, thiab cov khoom siv ntiv nplhaib ft sib txawv li qub ua rau tshwj xeeb tshaj yog cov qauv nrov.
Lub nplhaib 0-ntiv nplhaib muaj txiaj ntsig zoo hauv kev txo nqi txij nkawm nrog rau cov neeg ua haujlwm sib dhos los ntawm kev tshem tawm qhov kev kwv yees hauv kev xaiv lub sijhawm txuag no.
0-ntiv nplhaib muab kev yooj yim thiab siv tau yooj yim, yog li ua rau lawv zoo tagnrho rau kev thov thiab khaws cia.
Paub meej
Lub nplhaib sealing (ptfe coated nplhaib) muab cov elasticity thiab sealing zog ntawm cov roj hmab nrog cov tshuaj tiv thaiv ntawm Teflon. Nws yog ua los ntawm silicone lossis Viton roj hmab (fluororubber) cov tub ntxhais sab hauv thiab nyias nyias Teflon FeP (polyperfluorinated ethylene propylene) los yog Teflon Pfa (soluble polytetrafluoron) coated ua ke, cov roj hmab TEflon lub nplhaib no muab kev sib khi zoo heev.
Roj hmab O-ring yooj yim hnav, tshuaj tiv thaiv corrosion thiab roj permeability tsis zoo, ntshiab O-ring hardness yog siab dua los tiv thaiv compression tab sis tsis zoo elasticity. Teflon FeP / TeFLon PFA O-rings muaj kev sib raug zoo thiab tshuaj lom neeg ruaj khov (tshwj tsis yog tawm tsam los ntawm alkali hlau, fluorine thiab qee qhov halides ntawm qhov kub thiab txias) thiab muaj elasticity zoo nyob ze cov roj hmab O-rings, FeP / TeFLon pFA muaj cov coefficient tsawg heev. Kev sib txhuam (tsuas yog 0.1 txog 0.2) thiab ua haujlwm zoo heev rau cov pa permeability, uas ua rau lub nplhaib coated seals haum rau kev siv hnyav. Yog li ntawd, ptfe coated O-ring, es tsis txhob kim PERfluorinated roj hmab O-ring.
Muaj nuj nqi
Kev sib koom ua ke pub dawb thiab tsis sib xws ntawm teFLon FEP / TEFLon PFA txheej thiab cov roj hmab sab hauv cov tub ntxhais ua rau tag nrho lub nplhaib sib khi kom muaj kev sib khi zoo ib yam, elastic thiab compression ntawm txhua qhov taw tes ntawm lub nplhaib sib khi, tuaj yeem rov ua dua nyob rau hauv qhov kev txiav txim ntawm kev nruam. siab. Nrog rau qhov nce ntawm nruab nrab siab, lub nplhaib sealing yog compressed tag nrho. Lub nplhaib sealing zoo li cov kua viscosity siab, thiab lub siab ua haujlwm ntawm nws tau xa mus rau txhua qhov kev qhia yam tsis muaj kev txo qis.
Khoom siv
Teflon FEP thiab Teflon PFA yog qhov tseem ceeb zoo sib xws, tab sis teflon PFA muaj qhov kub zoo dua li Teflon FEP
Khoom txheej nplhaib sealing nplhaib yog *, ntau daim ntawv thov thiab zoo li qub foob thiab dynamic foob. Hollow silicone roj hmab coated nplhaib sealing nplhaib hlau txoj kab uas hla yog feem ntau loj, siv nyob rau hauv zoo li qub foob, nws hardness thiab compression kuj yog qis dua cov khoom tseem ceeb coated nplhaib sealing nplhaib.
Compression
Qhov muaj nyob ntawm feP txheej txheej ua rau lub nplhaib sealing muaj qhov ua tau zoo ntawm cov tawv tawv thiab brittleness tsis kam, thiab cov tub ntxhais sab hauv ua los ntawm silicone roj hmab los yog Viton roj hmab ua rau lub nplhaib sealing tseem tuav tau zoo elasticity nyob rau hauv qhov kub ntawm 205 ℃. Kev sib piv ntawm kev sib piv ntawm kalrez roj hmab (perfluoroether roj hmab), Viton roj hmab thiab feP coated nplhaib nyob rau hauv lub compression ntaus ntawv yog qhia nyob rau hauv daim duab: Kev ntsuam xyuas pom tau hais tias lub cev muaj zog ntawm silicone roj hmab los yog Viton roj hmab thiab Teflon FeP / TeFLon cov tshuaj muaj pes tsawg leeg. PFA tau muab tso ua ke los tsim lub nplhaib foob lub nplhaib, uas muaj kev sib zog zoo thaum tuav cov khoom siv roj hmab. Lub nplhaib coated seals yog tsim los nrog kev tswj xyuas nruj los ntawm kev siv cov txheej txheem tshwj xeeb uas Teflon FeP polymer yog coated tag nrho hauv cov roj hmab hauv cov tub ntxhais thiab O-ring yog ua raws li tus qauv yuav tsum tau ua. Cov ntaub ntawv siv tau qhia tias peb muaj kev cog lus zoo rau peb cov khoom siv cladding, uas yog raws li kev soj ntsuam kev ua tau zoo thiab kev tswj xyuas nruj kom ntseeg tau tias cov neeg siv khoom txaus siab thiab kev nyab xeeb ntawm cov khoom. Piv nrog rau lwm yam roj hmab los yog ntshiab TEflon o-ring, lub nplhaib sealing muaj kev sib khi tsis sib haum thiab lub neej ntev, tshwj xeeb tshaj yog hauv cov xov xwm hnyav.
Chemical Corrosion Resistance
Teflon FEP / Teflon PFA yog ib feem ntawm lub nplhaib cladding. Nws muaj kev tiv thaiv zoo heev rau tshuaj yaig. Ntawm qhov kev pabcuam kub ib txwm, Teflon FeP / Teflon PFA raug tawm tsam los ntawm ob peb cov tshuaj, thiab tsuas yog cov tshuaj tsis sib xws tau teev tseg ntawm no. Piv txwv li, qee cov hlau muaj zog hauv paus, fluorine thiab qee cov halides tsis sib haum nrog Teflon FeP / Teflon PFA.
Thaum raug Teflon FeP (pom zoo txwv kub: 204 ℃ / 400F) / Teflon PFA (pom zoo txwv kub: 260 ℃ / 500F), qee cov tshuaj nyob rau hauv siab concentrations yuav hnov mob nrog nws. Thaum kub siab, Teflon FeP / Teflon PFA yog corroded los ntawm cov organic tebchaw uas muaj 80% NaOH thiab KOH, hlau hydrides xws li boric acid (B2 H6), txhuas chloride, ammonia (NH3) thiab ib co amino acids (NH2) thiab imino (R. = NH). Hauv 80f ntau, cov tshuaj tiv thaiv oxidation ntev ntawm 70% nitric acid kuj tuaj yeem yog 80f.
Yog tias siv rau hauv cov xwm txheej no, cov khoom yuav raug kuaj tshwj xeeb. Ntxiv nrog rau cov tshuaj hais, lub nplhaib txheej yog feem ntau chemically inert rau lwm yam tshuaj.

Cov lus qhia rau kev txhim kho ntawm sealing nplhaib ntawm npog nplhaib
1, kev teeb tsa lossis los ntawm lub nplhaib sib khi ntawm lub nplhaib npog qhov yuav tsum tau ua kom du, tsis muaj burr, zawj thiab lub kaum ntse ntse, qhov profile ntawm lub qhov sab hauv yuav tsum ncav cuag 20 milliinches, ncej profile yuav tsum ncav cuag 10 milliinches.
2. Siv cov roj huv huv los yog roj pleev kom lub ntsej muag ntawm lub nplhaib sib khi thiab nws qhov sib cuag nrog cov khoom siv.
3. Yog tias lub nplhaib sib khi ntawm lub nplhaib npog yog qhov nyuaj rau nruab rau ntawm tus ncej, nws tuaj yeem muab tso rau hauv dej kub rau ob peb feeb kom nws nthuav dav. Lub softened thiab nthuav O-ring yog yooj yim rau nruab. Nruab lub O-ring thaum nws kub thiab rov qab mus rau nws qhov loj me thaum nws txias.
4. Tsis txhob khoov lub o-ring ntawm lub nplhaib cladding hnyav heev, txwv tsis pub nws yuav ua rau wrinkling ntawm teflon thiab cuam tshuam rau kev siv.
Qhov xav tau compression ntawm lub nplhaib sealing yog raws li hauv qab no
Static foob: 15% -20%
Dynamic foob: 10% -12%
Pneumatic mob: 7% -8%
Hla ntu
O-shaped seem coated nplhaib sealing nplhaib yog cov khoom lag luam, tau kawg, kuj tuaj yeem ua rau square thiab rectangular seem coated nplhaib sealing nplhaib, lub nplhaib sealing no yog siv rau qhov loj sealing nto thiab tuaj yeem tiv taus lub siab zoo, thiab nws qhov loj me me. tuaj yeem ua tiav nrog o-shaped seem coated nplhaib sealing nplhaib tib yam, tab sis nws yuav tsum tau qis qis dua.
O-section coated ring seals muaj ntau heev, square lossis rectangular seem coated nplhaib seals feem ntau yog siv rau qee lub sijhawm tshwj xeeb, thov hu rau peb lub tuam txhab lossis cov neeg xa khoom ua ntej xaj thiab sab laj.
Lub kaum sab xis ntawm lub nplhaib coated sealing nplhaib yog tsim los ua raws li qhov nominal aperture ntawm qhov kawg npog sealing nto, lub sealing gasket no hu ua coated rectangular sealing nplhaib, txheej txheej coated nrog teFLon FEP / PFA txawv specifications thiab diameters ntawm lub coated. rectangular sealing nplhaib loj series thiab lub nplhaib coated kuj ua tiav.
