Thaum tshav kub kub Resistance Brown FKM Viton Fluorine Rubber Sealing O-Nplhaib

Raw Material Formulation thiab Sourcing

Kev ua tau zoo ntawm fluorocarbon O- nplhaib yog qhov kev txiav txim siab los ntawm nws cov polymer muaj pes tsawg leeg. Peb cov xim av FKM O-rings yog tsim los siv high-purity fluoroelastomer puag polymers, feem ntau tsim nrog cov ntsiab lus fluorine ntawm kwv yees li 66% mus rau 68%. Cov qauv molecular tshwj xeeb no muab cov khoom siv nrog nws qhov kev tiv thaiv rau thermal degradation thiab tshuaj tua kab mob.

Peb muab peb cov khoom nyoos los ntawm cov chaw muag khoom thoob ntiaj teb uas tau lees paub los ua kom cov khoom sib xws - mus rau - batch sib xws. Raws li cov kev xav tau ntawm kev ua haujlwm tshwj xeeb, peb tuaj yeem muab tus qauv A FKM rau cov roj thiab roj ua haujlwm, lossis siab dua - fluorine Hom B thiab Hom F cov tshuaj tiv thaiv kom muaj zog tiv taus cov tshuaj tsw qab hnyav thiab cov kua qaub ib puag ncig. Rau cov ntawv thov uas xav tau kev txhim kho qis - qhov kub thiab txias, cov qauv GFLT tshwj xeeb muaj. Tag nrho cov ntaub ntawv raug muab sib xyaw nrog cov neeg ua haujlwm kho kom raug thiab cov muab tub lim kom ua tiav lub hom phiaj lub cev, thiab peb ua kom ua raws li RoHS cov qauv los lav qhov tsis muaj cov tshuaj phom sij txwv.

Manufacturing Precision thiab Quality Assurance

Peb cov txheej txheem tsim khoom siv cov txheej txheem compression molding siab tshaj plaws rau qhov siab -kub curing xav tau ntawm FKM. Precision- cov pwm tshuab ua kom ntseeg tau tias O- cov nplhaib ua tau raws li qhov ntsuas qhov ntev, feem ntau ua raws li AS568, ISO, lossis JIS cov qauv. Tus ntoo khaub lig-linking ceev tau tiav thaum lub sij hawm molding thiab tom ntej ncej- cov txheej txheem kho yog qhov tseem ceeb; nws ncaj qha cuam tshuam rau O-ring's compression teeb thiab ntev- lub sij hawm sealing kev ntseeg siab nyob rau hauv tas li thermal stress.

Kev tswj xyuas zoo yog kev koom ua ke rau hauv peb cov kab ntau lawm. Peb ua cov kev ntsuam xyuas lub cev tag nrho ntawm txhua qhov ntau lawm, txheeb xyuas qhov tsis xws li Shore A hardness (tus qauv ntawm 70, 75, lossis 90), tensile lub zog (10-16 MPa), thiab elongation ntawm tawg (150-300%). Compression set test yog ua nyob rau ntawm qhov kub siab (xws li, 200℃rau 70 teev) kom paub meej tias cov khoom khaws nws elastic rov qab. Kev tshuaj xyuas qhov ntev yog ua los ntawm kev siv cov khoom sib piv kho qhov muag thiab kev sib koom tes ntsuas cov tshuab kom paub meej qhov tseeb ntawm geometric, uas yog qhov tseem ceeb rau kev tiv thaiv kom tsis txhob muaj kev sib tsoo hauv cov ntawv thov kev sib khi zoo thiab zoo li qub.

Functional Performance thiab Application Suitability

Lub luag haujlwm tseem ceeb ntawm peb cov xim av FKM O-rings yog lawv qhov tshwj xeeb thermal stability. Cov ntsaws ruaj ruaj no yog tsim los rau kev ua haujlwm tas mus li ntawm qhov kub txog li +200 degree, nrog rau qee cov qib tshwj xeeb muaj peev xwm tiv taus qhov cuam tshuam tas mus li mus txog +240℃thiab tsis sib haum xeeb nce mus txog +280℃. Qhov kev tiv thaiv thermal no tseem ceeb tshaj li tus qauv NBR lossis EPDM elastomers.

Chemically, cov ntsiab lus fluorine siab muab kev tiv thaiv zoo rau ntau yam roj av- raws li cov kua dej, suav nrog cov roj ntxhia, cov roj ntsha hluavtaws, roj av (xws li ethanol blends), diesel, thiab aviation fuels. Cov khoom siv kuj qhia tau tias muaj zog tiv thaiv ozone, UV hluav taws xob, thiab kev laus hauv huab cua, ua kom lub neej ua haujlwm ntev nyob rau sab nraum zoov lossis ib puag ncig hnyav. Tsis tas li ntawd, FKM nthuav tawm cov pa roj tsawg tsawg, ua rau nws tsim nyog rau lub tshuab nqus tsev thiab roj-cov khoom siv.

Nws yog ib qho tseem ceeb kom nco ntsoov cov kev txwv kev ua haujlwm ntawm FKM kom paub meej tias daim ntawv thov raug. Cov O-rings no tsis pom zoo siv nrog cov dej kub, chav dej, lossis ethylene glycol brakes, qhov twg EPDM feem ntau tsim nyog. Tsis tas li ntawd, FKM nthuav tawm cov kev tiv thaiv tsis zoo rau qis -molecular- hnyav ketones thiab esters, uas tuaj yeem ua rau o thiab degradation. Peb qhia cov neeg siv los txheeb xyuas cov tshuaj sib raug zoo raws li cov kua dej tshwj xeeb, qhov kub thiab txias, thiab lub sijhawm raug xa tawm ua ntej xa mus.

OEM Engineering Support

Peb muab kev txhawb nqa dav dav los pab cov neeg siv khoom hauv kev xaiv cov khoom siv thiab foob tsim. Peb pab neeg ua haujlwm engineering tuaj yeem ntsuas qhov kev ua haujlwm tshwj xeeb - suav nrog cov kua dej tawm, lub voj voog kub, thiab cov xwm txheej siab - kom pom zoo FKM qib zoo thiab cov qauv sib xyaw. Nrog rau hauv - lub tsev cuab yeej thiab cov peev txheej tsim tau yooj yim, peb ua raws li kev tsim qauv thiab siab - ntim khoom, kom ntseeg tau tias peb cov O-rings xa cov kev ua tau zoo sib xws, txhim khu kev qha hauv cov ntawv thov tseem ceeb.
