EPDM vs. Silicone: Xaiv txoj cai Gasket rau Dej Systems

 

EPDM (Ethylene Propylene Diene Monomer) yog ib qho saturated copolymer elastomer nrog cov qauv molecular ruaj khov, tsim rau kev laus sab nraum zoov, dej raus dej thiab qhov chaw ib puag ncig tiv thaiv. Muaj-qib EPDM tau txais peroxide vulcanization los txo cov txheej txheem compression thiab txhim kho hydrolysis stability nyob rau hauv kev sib cuag dej tas li.

Silicone (VMQ) yog ib qho hluavtaws siloxane -raws li elastomer. Nws nta zoo thermal stability thiab qis - qhov kub thiab txias yooj yim tab sis nqa lub zog tensile qis dua thiab ua rau tsis zoo dua li EPDM. Tus qauv silicone gaskets siv rau qhov zoo li qub, qis-kev sib txhuam dej sib khi qhov xwm txheej yam tsis muaj kev siv tshuab ntau zaus lossis kev caij tsheb kauj vab.

 

 

Tag nrho cov npe tsis tau raug kuaj raws li cov txheej txheem dej kev ua haujlwm: 0-16 bar ua haujlwm siab, 23℃ambient kub hauv qab, 720-teev dej tsis tu ncua. Dimensional stability, mechanical retention thiab aging resistance data ncaj qha qhia gasket specification rau cov kav dej, dej hauv nroog thiab cov dej hauv dej.

 

 

 

Peroxide-vulcanized EPDM yog cov kav dej hauv nroog, cov dej ntws tawm thiab cov kav dej kub sib khi vim nws cov dej- tshwj xeeb lub cev ruaj khov. Nws cov pob txha pob txha saturated polymer tiv thaiv hydrolysis thiab oxidative aging nyob rau hauv ntev - kev pab cuam submerged.

Tsawg Dej Swelling Deformation: EPDM tuav ntim ntim o Tsawg dua lossis sib npaug li 2.5% tom qab 30-hnub puv dej raus dej. Nws tsis txhob muaj gasket bulging, flange extrusion gap blockage thiab bolt torque tsis ua hauj lwm ntau nyob rau hauv cov kav dej kav dej.

Superior Steam Aging Performance: EPDM khaws elasticity thiab cov qauv kev ncaj ncees nyob rau hauv 134℃saturated steam cycling. Nws yog thawj qhov kev xaiv elastomer rau siab -kub kub boilers thiab sterilization dej circuits.

High Mechanical Fatigue Resistance: Nrog lub zog tensile siab tshaj 20 MPa thiab qis compression teeb, EPDM tiv taus cov dej siab hloov pauv txhua hnub (0-16 bar) thiab cov kav dej micro- hloov pauv yam tsis muaj deformation mus tas li.

Certified haus dej nyab xeeb: Kev cai tsim EPDM gaskets dhau NSF 61 thiab WRAS cov qauv, tso tawm tsis muaj cov dej tsis huv hauv cov dej sib kis.

 

 

Silicone VMQ gaskets pab niche siab -kub thiab ultra- qis- qhov kub thiab txias dej sealing scenarios qhov twg EPDM kub ciam teb tsis tuaj yeem npog. Nws cov qauv siloxane molecular muab cov thermal stability thiab lom neeg inertness.

Ultra-Wide Temperature Adaptability: Silicone tseem hloov tau los ntawm -60℃dej khov ib puag ncig mus rau 200℃high-temperature water equipment. Nws tsis txhob nkim cracking nyob rau hauv cryogenic tej yam kev mob thiab thermal aging nyob rau hauv huab cua kub.

Khoom noj khoom haus-Qib Inert Surface: Txheem silicone gaskets tsis muaj - tshuaj lom, tsw -dawb thiab tsis yog - nag lossis daus. Lawv siv rau cov khoom siv dej haus, cov tshuab ntxuav dej thiab khoom noj khoom haus -qib cov tshuab ua dej.

Tsawg Hysteresis Performance: Silicone tuav ruaj khov elastic rov qab nyob rau hauv qis - zaus compression zoo li qub. Nws muab kev sib khi zoo sib xws rau cov flange tsis tu ncua thiab qis -load dej sealing qauv.

 

 

Cov khoom siv tsis sib haum ua rau maj mam to, gasket bulging thiab ua tsis tiav ntxov hauv dej ua haujlwm. Pawg tsim thiab kev yuav khoom yuav tsum ua raws li qhov xwm txheej- raws li txoj cai xaiv.

Xaiv EPDM Rau: Cov kav dej hauv nroog, cov dej kub ntws, cov khoom siv dej sib xyaw, cov chaw dej tawm sab nraum zoov, cov twj tso kua dej twj tso kua mis sealing, thiab ntev - lub sijhawm ua haujlwm tsis tu ncua.

Xaiv Silicone Rau: Ultra-qis-kub cov kav dej khov, siab- cov khoom siv dej zoo li qub siab tshaj 140 degree, zaub mov- qib cov dej ntim dej, cov khoom siv kho dej huv, thiab qis- voj voog zoo li qub sealing qauv.

Kev xaiv yuam kev: Siv silicone rau dynamic dej kev sib txhuam scenarios ua rau sai sai nto abrasion thiab to. Siv EPDM rau ultra-siab- kub zoo li dej siab tshaj 140℃ua rau kom ceev thermal aging thiab nce compression set.

 

 

Kev xa tawm tsis raug cai tshem tawm cov kev ua haujlwm tsis sib xws thiab ntawm -qhov chaw haum tsis ua haujlwm thaum lub sijhawm ntau thiab OEM kev yuav khoom:

1. Kev ua haujlwm nruab nrab: kais dej, circulating industrial dej los yog siab -kub chav dej

2. Nruam thiab siab kawg ua haujlwm kub

3. Kev ua haujlwm ruaj khov thiab siab hloov pauv ntau yam

4. Sealing type: Static flange sealing lossis dynamic cyclic sealing

5. Daim ntawv pov thawj yuav tsum tau: NSF 61, WRAS lossis zaub mov- ntawv pov thawj qib

6. Qib Hardness: Standard Shore A 60/70/80 rau dej sib txuam

7. Ib puag ncig kev pabcuam: Kev teeb tsa hauv tsev ruaj khov lossis huab cua sab nraum zoov- ua haujlwm raug

 

 

EPDM yog qhov siab -kev ntseeg siab, tus nqi- ua haujlwm zoo rau cov dej hauv nroog thiab kev lag luam feem ntau sealing, xa cov dej tsis tshua muaj o, tsis tshua muaj compression teeb thiab kev ua haujlwm zoo heev. Silicone lub hom phiaj siab heev - qhov kub thiab huv - qib dej zoo li qub qhov twg EPDM kev ua tau zoo ciam teb yog txwv. Kev xaiv gasket yuav tsum ua qhov tseem ceeb ntawm kev ua haujlwm kub, cov khoom siv thauj khoom thiab cov ntawv pov thawj es tsis yog hloov khoom siv thoob ntiaj teb. ruaj khov batch vulcanization zoo ua kom ntev -lub sij hawm dej kaw lus sealing kev nyab xeeb.
