CZPT plastic Acetal Trackwheel
POM&lparPolyformaldehyde&rpar is a engineering plastics of non-facet-chain&comma high density&comma higher crystalline and linear polymer&comma which is praised “CZPT Metal”&comma and has thorough outstanding performances&comma such as&colon Dress in-resistance&comma high hardness&comma anti-impregnant&comma great rigidity &lparTensile modulus of elasticity&rpar&comma chemical balance&comma isolation resistance and dimensional stability&interval POM has broadly utilized in Car industries&comma digital and electrical goods&comma commodity&comma pipeline & fittings&comma actual equipment and so on&comma which can be alternatively of the bronze&comma Zinc&comma tin and other metals&time period
Other than POM-H is often copolymerized with ethylene oxide with each other&comma in order to avoid the melting of POM materials in the large temperature&interval POM-H has the far better performances than POM-C in its large crystalline&comma mechanical strength and rigidity&interval And POM-C has the better performances than POM-H in its minimal melting stage&comma temperature balance&comma fluxion attribute and machining capability&period
Father much more&comma POM-H&plusPTFE&comma which is manufactured from the Delrin POM Resin that maxed Teflon fiber symmetrically&comma has the low co-effective of frication&comma excellent lubrication&comma dress in-resistance&comma non-creepage resistance&interval
Car industries&colon POM has a big application in car industries&comma because the mechanical elements created by POM&comma which has the positive aspects of substantial mechanical strength&comma higher hardness&comma excellent put on-resistance&comma minimal co-productive of friction&comma simple to preserve&comma lowering expense and so on&comma can be utilized in cars as an alternative of coppery fifty percent stalk and earth equipment&period It not only saving copper resources&comma but also improving provider lifestyle&period At the engine gas program&comma factors for hose valves and situation protect of radiator&comma cooling fluid’s standby circumstance&comma drinking water valve&comma oil box’ protect&comma pump impeller&comma shell of gasification machine and accelerator pedal and so on&period
Digital and electrical CZPT&colon Since of its decrease electricity consuming&comma large dielectric strength and insulation resistance and electronic arc resistance&comma POM has commonly applied in digital and electric powered CZPT&comma this kind of as&colon Shell of digital spanner&comma shell of electronic scissors&comma shell of coal drilling equipment&comma take care of of swap&comma elements also for telephone&comma wi-fi recorder&comma video clip tape recorder&comma television&comma pc&comma electrograph&comma calculagraph&comma bracket of recorder tape and so on&interval
Agricultural device&colon Component of manual sprayer&comma joint and transport component of seeder&comma components of milk machine&comma shell of irrigation and drainage&comma valve&comma joint and bush of water and so on&time period
Other discipline&colon
Pharmacy & packing Device&colon Transporting screw&comma planet gear&comma equipment bar&comma chain wheel and cushion bar and so on&period
CZPT industries&colon H2o faucet&comma window body&comma wash pot&comma water tank&comma pulley for portiere&comma shell of water meter and tie-in of drinking water pipe&interval
