"Peb lub siab" kev ua yeeb yam dhau ntawm NBR **

HNBR (Hydrogenated Nitrile Roj Hmab) yog ib qho kev hloov kho ntawm cov roj hmab nitrile (NPR). Los ntawm hydrogenation cov txheej txheem, nws qhov kub tsis kam, tshaj tawm tsis kam thiab kev laus kuj yog kev txhim kho zoo heev:

✅ Kub Kub Kuj: {{{}} degree ~ {{} degree (txog 200 degree rau 120 degree txwv ntawm NBR

✅ Kev Ntsuas Siab Tshaj: Zoo li qub qis dua lossis sib npaug rau 40mpa, dynamic ntim tsawg dua lossis sib npaug, haum rau cov haujlwm ua haujlwm siab

✅ tiv taus cov roj muaj zog, acid thiab alkali resistant, xws li cov ntxhiab tsw hydrocarbons, ketones), lub neej ntev yog 3 ~ 5 zaug ntawm NBR

✅ anti-nkees: COMPRESSION deformation tus nqi<15% (70℃×22h), long-term elastic sealing

Scenario-raws li kev mob mob kis pom tseeb **:

Q1: Yuav ua li cas xaiv HNBR thiab Fluororubber (FKM) sealing gaskets hauv cov mateholes?

A1:

Hnbr Zoo: Tiv thaiv kom kub ntawm 180 degree + siab siab ntawm 40mpa, compression teeb<15% (20% for FKM), cost only 60% of FKM, suitable for pressurized scenes with oil/water as the main medium (such as reactor in refinery).

FKM cov txiaj ntsig: resistant rau ultra-siab kub ntawm 25MPA), haum rau muaj kev sib tw zoo nkauj thiab muaj kev sib npaug nrog cov khoom siv tshuaj lom neeg).

Cov ntaub ntawv txhawb: kev sib piv ntawm cov dej hiav txwv ethylene qhia tias lub neej ntawm Hnbr hauv Ul 150 Qib Kub dua tias ntawm FKM (Source: Seem thev naus laus zis xov xwm kaw lus 2024).

Cov Ntsiab Lus: HNBR VS FKM, xaiv ntawm nias cov khoom siv Manhole Sealing

Q2: Npaum li cas ntawm HNBr gasket ntawm tus manhole guhole cuam tshuam rau kev sib khi ua tau zoo? **

A2:

Qhov zoo tshaj compression tus nqi: 15% ~ 20% (raws li ASME PCC {2}} qauv). Tsawg dhau yuav ua rau tsis txaus ntseeg, thiab siab dhau yuav ua rau tsis ua hauj lwm.

Kev Ntsuas Txoj Kev: Siv micrometer ntsuas ntsuas cov tuab ua ntej thiab tom qab compression. Piv txwv li, ib daim ntaub qhwv tuab 5 hli yog tsim nyog thaum compressed rau 4. 0 ~ 4.25mm.

Cov ntaub ntawv: Lub hoobkas muaj tshuaj tsis muaj zog vim muaj kev tsis muaj menyuam yaus ntawm tsuas yog 10% (siv los ntawm cov ncej qub thall). Tom qab hloov kho, lub hanbr pad tsis muaj teeb meem rau 3 xyoos.

Cov Lus Qhia Kev: Muab cov qauv Compression "Compression xam: Cail

Q3: Dab tsi yog qhov sib txawv ntawm API 6A ntawv pov thawj HNBR pob thiab cov ntaub qhwv zoo tib yam? **

A3:

Daim ntawv pov thawj yuav tsum muaj: hla API 6A Annex F ({}}}}}} mppe cov cuab yeej thiab cov khoom siv siab.

Kev ntsuas cov ntaub ntawv: tus nqi to ntawm ib qho API 6A gasket yog tsawg dua {}}}}}. {Degree ntawm 150 degree thiab 35mpa.

Yuav cov lus qhia: Cov qauv uas tau ntawv kawm tau rau cov roj thiab roj) lossis FDA (zaub mov) muaj rau lwm cov lag luam.

Q4: Yuav ua li cas tiv thaiv cov HNBR ncoo los ntawm kev ntxuav kom deb li thaum hloov nws lub siab? **

A4:

Peb-kauj ruam txoj haujlwm:

Txo cov siab kom tsawg dua lossis sib npaug nrog 1.6mpa thiab siv lub clamp tshwj xeeb los txhim kho lub manhole npog;

Digen lub bolts diagonally (1/4 tig txhua lub sijhawm) kom tso cov kev ntxhov siab uas muaj kev ntxhov siab;

Tso cov cuab yeej ua ke tawm ntawm cov cuab yeej ua kom cais cov flange kom tsis txhob ua kom muaj kev sib tsoo ntawm cov nplaim khi ncaj qha.

Q5: Dab tsi "15% compression teeb tus nqi" ntawm HNBR PUAJ txhais li cas? **

A5:

Lus Txhais: Tom qab compression ntawm 70 degree rov qab tus nqi yog ntau dua los yog sib npaug rau 85% (tus nqi me dua, qhov zoo dua).

Kev sib piv: NBR ncoo deformation tus nqi> 30% (loses elasticity tom qab hardening), silicone ncoo> 25% (tsis yog roj resistant).

Kev cuam tshuam lifespan: Rau txhua 5% nce rau hauv deformation tus nqi, cov nyiaj tau luv los ntawm 40%. Piv txwv li: Lub zog hluav taws xob cog siv HNBR cov ntaub qhwv nrog tus nqi deform yog li 12%, thiab lub sijhawm ntsuas yog 18 lub hlis).

Q6: Qhov kev txiav txim yam tsawg kawg nkaus rau customized tshwj xeeb zoo li tus txiv neej HNBR siab lub manhole pob khoom?

A6: Raws li qhov loj me ntawm cov ntawv sau thiab cov ntaub ntawv siv rau lub tshuab.

Q7: Ntev npaum li cas tau Hann tuaj yeem siv hauv cov kua ammonia xov? **

A7:

Cov ntaub ntawv ntsuas: Dhau ISO 1817 Kua Ammonia kev ntsuam xyuas (70 Degree × 168h), hloov pauv mus rau 3%, hardness hloov ± 5 ntug dej A.

Kev twv ua neej: Nruam kev sib cuag nrog kua ammonia ({}}}} {1 ~ 36 lub hlis hloov pauv).

Cov Lus Ceeb Toom Txaus Siab: Nws raug nquahu kom ua kev tiv thaiv kev hloov pauv txhua 18 lub hlis. Cov "kua ammonia khoom ntim cov khoom txij nkawm kev voj voog" yog muab.

Q8: Dab tsi yog torque zightening txheem txheem txheem rau hanbr pads rau cov manicurized? **

A8:

Tus Qauv Siv: Raws li ASME B16.5 Flange Torque rooj, lub zog ntawm HNBr Gaskets xav tau 15% siab dua li ntawm NBR GASKETS (vim yog lub siab tawv ntawm cov khoom siv).

Piv txwv li: DN200 PN16 Flange, pom zoo lub zog 450 n· m (tighten txawv kab ntsig peb zaug, nce los ntawm 30% txhua lub sijhawm).

TUAM Cov lus pom zoo: Siv cov Dital Serene Wrench kom tsis txhob muaj ntau nrawm thiab ua rau lub gasket rau nyem cov qauv: CDI 300NT · m).

Q9: Tau HNBR cov ntaub qhwv tau siv rau hauv cov pa nyem tua hauv lub tshuab nqus tsev? **

A9:

Muaj feem xyuam mob: nqus tsev kawm ntawv tsawg dua lossis sib npaug ntawm {{0mpa (kub siab dua lossis sib npaug, nruab nrab dawb ntawm kev pom impurities.

Cov qauv tsim tshwj xeeb: peb lub tshuab nqus tsev zoo li cas rau lub ntsej muag zoo li no ** (1.5mm tuab) los tiv thaiv kev sib tsoo hauv lub siab tsis zoo, thiab dhau mus iso 28769 lub tshuab nqus xau (toleage tus nqi<1×10⁻⁶ Pa·m³/s).

Q10: Yuav ua li cas txheeb xyuas qhov tseeb ntawm HNBR cov ntaub ntawv tshaj tawm los ntawm kev ceeb toom thib peb?

A10:

Yuav tsum kuaj xyuas qhov ntsuas:

① Infrared Spectrum (IR): HNBR cov xeeb ceem peaks yog ntawm 2920cm⁻¹ (ch₂), 1630cm⁻¹ (c {m residue<1%);

② Noney viscosity (ml 1+4 100 degree): 45 ~ 65 (siab dhau yog kev rov qab siv roj hmab);

Density: 1.03 ~ 1.08G / cm³ (NPRR≈1.2, FKM≈1.8).

Kev soj ntsuam tswv yim: SGS, TÜV thiab lwm cov tsev qhia.
