Iko kuoma, kuoma uye kusimba kwePTFE zvinhu, zvishoma.Simba rayo rekusimba i21-28 MPa, kukotama simba i11-14 MPa uye kureba i250% -300%.Icharemara pasi pekunetseka kwenguva refu uye inowanzo kwira kana yaremerwa.Iwo ari pamusoro pekuita maitiro ePTFE, anotungamira kune yakasarudzika maitiro maitiro kana uchishandisaPTFE firimu skiving muchinakucheka.
1. Masimba madiki ekucheka.Nekuda kwekuoma, simba, uye kuoma kwePTFE kuve kwakaderera, pasi pemamiriro akafanana ekucheka, iyo huru yekucheka simba rekucheka 45 simbi ndeye 14-20 nguva iyo ye.film skivingPTFE zvinhu.
2. PTFE firimu rine diki kupisa conductivity, chete 0.27W/MK-1, pamwe chete yakaderera kupisa-rinodzivirira tembiricha, ayo yakakwirira kupisa-kupisa tembiricha chete 250 ℃.Kana iyo firimu skiving volume yakakura kwazvo, kukurumidza kucheka kwakakwira, uye tembiricha yekucheka yeworkpiece ichakwira, iyo inopfavisa iyo PTFE zvinhu, uye kunyange kunyungudika, coking, uye "sticky banga" chiitiko.Pamberi pekucheka, iyo isina chinhu inorapwa nemamiriro ekuita 30-50 madhigirii Celsius pamusoro pekushisa kwekushanda uye nguva yekurapa ye24h kana kupfuura, kudzikamisa kurongeka kweiyo firimu skiving process.
3. Teflon ine coefficient yakakura yekuwedzera kwekushisa.Naizvozvo, PTFE zvinhu mufirimu skiving process inoburitsa huwandu hukuru hwekupisa nekuda kwekukweshana, nyore-ku-turusi, uye workpiece yemuno kupisa.Izvi zvinotungamira kune elastic deformation yePTFE workpiece nekuda kwekupisa, izvo zvinozopedzisira zvakanganisa kunaka kwepamusoro uye dimensional kurongeka kwePTFE workpiece.
4. Kuenzaniswa nezvinhu zvesimbi, modulus ye elasticity yePTFE yakaderera zvikuru.Kana iyo yekucheka chikafu chakanyanya kana kukurumidza kukurumidza, iyo yakakura kugadzirisa friction uye simba rinoiswa kune workpiece nechishandiso chinoshanda pamwechete.Mhedzisiro ndeye deformation yakakura yePTFE workpiece, iyo inokanganisa machining kurongeka kwePTFE workpiece.
5 Kuti mvura yekucheka firimu ishande nemazvo, zvinotevera zvakakosha zvinofanirwa kucherechedzwa: kushandiswa kwemvura yakapfava, kugara uchitarisa kutarisa, kugara uchiwedzera biocides, kucheneswa kwematurusi emuchina, kubviswa kwedhaka uye chiyero, kusanganiswa kwemvura yekucheka.
