PTFE Raina Whakarahi Rubber Hangarau Hononga
Whakaahuatanga
Ko nga hononga roha rapa o te PTFE he ahuatanga o te whakaheke wiri, te aukati i te waikura, te waikawa me te aukati alkali, te aukati teitei o te pāmahana, te ngawari me te aukati, te nuinga e whakamahia ana mo te hurihanga paipa, te whakarereketanga o te rahi me te hononga wahi wiri, ka taea te whakamahi hei tuku me te whakaheke wai. paipa mo te peihana, te hangarau matū, te waikura, nga taputapu motuka waka, me etahi atu whakamahinga motuhake.
He poto te PTFE mo te Polytetrafluoroethylene, e mohiotia ana ko Teflon, 4F.PTFE he pai pūmautanga matū me te waikura ātete, te reira tetahi o te rauemi waikura ātete pai i roto i te ao, haunga konutai konutai me te fluorine wai, PTFE he ātete ki matū katoa, whakamahia whānuitia i roto i te taiao ha'iriiri katoa.I tua atu, he pai nga taonga hiri, he taonga whakahinuhinu teitei, he taonga whakamaarama hiko, he pai te pakeke o te koroheketanga, he parenga pāmahana (ka roa te mahi i waenga i te -180 ℃ ki te 250 ℃).
Ko nga waahanga hua o nga hononga roha rapa PTFE raina:
Te ātete ki te pāmahana teitei: te pāmahana mahi ki te 250 ℃.
He iti te parenga o te pāmahana: he pai te kaha o te miihini, ahakoa ka heke te pāmahana ki te -196 ℃, ka taea e ia te pupuri i te 5% elongation.
Te aukati waikura: te aukati ki te nuinga o nga matū.
