FPM Extrusion Round Foob

FPM raug xaiv rau nws cov tshuaj lom neeg ruaj khov thiab thermal resilience. Lub hauv paus polymer muab kev tiv thaiv rau ntau hom kua dej, suav nrog aliphatic hydrocarbons, cov kuab tshuaj tsw qab, thiab cov roj ntxhia. Hauv peb qhov chaw tsim khoom, peb siv cov FPM cov ntsiab lus tshwj xeeb kom haum rau qhov chaw ua haujlwm. Rau cov qauv siv, cov khoom tuav elasticity nyob rau hauv qhov kub ntawm -20℃rau +200℃. Rau cov kev cai tshwj xeeb, xws li raug rau cov chav lossis qhov chaw uas muaj qhov kub thiab txias, cov qauv hloov kho muaj. Lub compound yog sib xyaw ua ke los xyuas kom meej qhov sib txawv ntawm cov curatives thiab fillers, uas ncaj qha cuam tshuam rau qhov kawg foob lub compression teeb thiab tensile lub zog.

Tsis zoo li molded seals, extruded round seals yog tsim los ntawm cov txheej txheem nruam vulcanization. Raw FPM compound raug yuam los ntawm qhov tseeb tuag kom ua tiav lub hom phiaj hla -sectional txoj kab uas hla. Txoj kev no tso cai rau kev tsim cov khoom siv ntev ntev, uas tuaj yeem txiav mus rau qhov ntev tshwj xeeb lossis muab rau hauv cov yob ntau rau kev ua teb.

Dimensional kam rau ua yog nruj me ntsis saib xyuas thaum extrusion. Peb tuav tswj nruj ntawm txoj kab uas hla sab nraud (OD) thiab sab hauv txoj kab uas hla (ID) kom ntseeg tau tias muaj kev sib raug zoo nrog cov qauv caj pas. Tom qab-extrusion, cov khoom tau dhau los ua lub voj voog thib ob hauv qhov cub convection. Cov ntawv tshaj tawm no -kev kho cov kauj ruam yog qhov tseem ceeb los ua kom tiav tus ntoo khaub lig- txuas cov tshuaj tiv thaiv, tshem tawm cov khoom lag luam tsis zoo, thiab ua kom lub cev ruaj khov ntawm elastomer. Yog tias tsis muaj kev tshaj tawm txaus- kho, cov ntsaws ruaj ruaj yuav muaj kev cuam tshuam ntau dhau los yog tawm hauv lub tshuab nqus tsev lossis siab - cov ntawv siv cua sov.

Quality Assurance and Testing Protocols
Txhua pawg tsim khoom tau dhau mus kuaj nruj ua ntej tso tawm. Peb tsis cia siab rau cov ntaub ntawv xa khoom; Hloov chaw, peb txheeb xyuas cov khoom vaj khoom tsev hauv -tsev. Standard xeem muaj xws li:

Hardness:Ntsuas hauv Shore A kom paub meej tias qhov sib xws.

Tensile Strength & Elongation ntawm Break:Txhawm rau ntsuam xyuas mechanical durability.

Compression Set:Ntsuam xyuas tom qab 22 teev ntawm qhov kub siab los kwv yees ntev - lub sij hawm sealing quab yuam tuav.

Dej Resistance:Cov qauv yog immersed nyob rau hauv cov roj siv thiab cov kua qaub los ntsuas qhov ntim hloov thiab hardness hloov.

Kev kuaj pom pom kuj tseem ua los txheeb xyuas qhov tsis xws luag xws li porosity, khawb, lossis cov kab ntws uas tuaj yeem cuam tshuam kev sib khi. Thaum extruded seals ib txwm ua kom pom qhov sib txawv ntawm qhov sib txawv piv rau kev txhaj tshuaj- cov khoom molded, peb xyuas kom meej qhov zoo ntawm qhov chaw ua tau raws li cov qauv kev ua haujlwm rau kev siv dynamic thiab zoo li qub.

FPM extrusion round seals yog tsim rau siv nyob rau hauv hydraulic thooj voos kheej kheej, automotive roj systems, chemical processing equipment, thiab aerospace fluid tuav. Txawm li cas los xij, daim ntawv thov tsim nyog yuav tsum ua raws li kev txwv engineering. FPM feem ntau tsis pom zoo siv nrog cov dej kub, chav dej (tshwj tsis yog tsim tshwj xeeb), lossis qee yam amines thiab ketones.

Thaum txhim kho extruded seals, nws yog ib qho tseem ceeb uas yuav tsum tau them nyiaj rau cov kab sib koom ua ke yog tias lub foob tau txuas rau ntawm -site. Rau kev siv dynamic, deg roughness ntawm mating hardware yuav tsum tau khaws cia ntawm Ra 0.2 thiab Ra 0.8 µm kom tsis txhob hnav abrasive. Lubrication tau tshaj FPM yuav tsum tau siv thaum lub sij hawm sib dhos kom tsis txhob qhuav - pib puas.
