PTFE Yakavharidzirwa o-mhetemao-mhete anosanganisira isina musono uye yunifomu PTFE FEP/PFA encapsulation/jaketi iyo inovhara zvachose chinhu chakakosha Viton® fluoroelastomer (inowanikwawo musilicone).Iko kusanganiswa kwezvikamu izvi kunogadzira o-mhete inenge iine makemikari inert uye compression set inopokana kuti ishandiswe munzvimbo dzakaoma dzekusunga.Yakavharidzirwa o-mhete inoderedza nguva yekudzikira uye nekudaro inowedzera pundutso pese painoparadza mvura nemagasi zvinokonzeresa kutadza kusimbiso nguva isati yakwana.
Iyo PTFE inopa isina tsvimbo pamusoro pekucheneswa kuri nyore kwezvinhu zve viscous.Mao-ringing aya ane low coefficient of friction ye .2 pasimbi uye o-ringing pamusoro ari self lubricating.Iyo PTFE encapsulation inoita kuti o-mhete ive nehutsanana nekubvisa kusvibiswa kwemvura nema elastomers.Iwo ma-o-mhete anogona sterilzable uye autoclavable, FDA inoenderana, USP Kirasi VI inoenderana, NSF kutevedzera kunowanikwa kune chaiwo maapplication.
Encapsulated o-mhete dzakanyatsogadzirirwa kugadzirisa dambudziko rekuisa chisimbiso chemakemikari ane hutsinye uye kupisa kwakanyanya.Yakavharidzirwa o-mhete ine yakasimba kana buri elastomeric core yakavharidzirwa muPTFE FEP kana PFA sheath.Iyo elastomeric musimboti inogona kunge iri fluorocarbon kana silicon rabha.Solid core yakavharidzirwa o-mhete inowanzo shandiswa mune static application.Hollow Silicone core yakavharidzirwa o-mhete inowanzoshandiswa mumashandisirwo apo simba rekuisa chisimbiso rinodiwa sezvakaita semi dynamic application.Iyo yakavharidzirwa o-ring inopa mhinduro inoshanda kune akawanda akaoma maapplication.Iyo PTFE FEP kana PFA encapsulation inobata chisimbiso uye elastomeric musimboti inosimbisa kunoenderana kudzvanywa pachisimbiso.Mhedzisiro ndeyekumanikidza kwekuvhara kwese, kunowedzera nekumanikidza kwepakati.Iyo yakavharidzirwa o-ring inoita semvura inopenya kwazvo, chero kumanikidza kunoitwa pachisimbiso kunofambiswa munzira dzese.Kunyanya kupisa tembiricha yeFEP i205°C (400°F) uye yePFA 260°C (500°F).
