Ndezvipi zvinhu zvekuvhara mavharuvhu zvinowanzo shandiswa?

Kune mhando dzakawanda dzemavharuvhu, asi basa rekutanga rakafanana, kureva kubatanidza kana kudzima kuyerera kwepakati. Saka, dambudziko rekuvharwa kwevharuvhu rakakurumbira zvikuru.

Kuti vharuvhu ikwanise kudzima kuyerera kwepakati pasina kubuda kwemvura, zvakakosha kuve nechokwadi chekuti chisimbiso chevharuvhu hachina kukanganiswa. Pane zvikonzero zvakawanda zvekubuda kwevharuvhu, zvinosanganisira dhizaini isina musoro yekuvaka, nzvimbo isina kugadzikana yekubatanidza, zvikamu zvekusunga zvisina kurongeka, kusabatana zvakanaka pakati pemuviri wevharuvhu nebhoneti, nezvimwewo. Matambudziko ese aya anogona kukonzera kusavhara zvakanaka kwevharuvhu. Saka, zvichikonzera dambudziko rekubuda kwemvura. Naizvozvo, tekinoroji yekuvhara mavharuvhu itekinoroji yakakosha ine chekuita nekushanda kwevharuvhu uye mhando, uye inoda tsvakiridzo yakadzama uye yakarongeka.

Zvinhu zvinowanzoshandiswa zvekuvhara mavharuvhu zvinosanganisira mhando dzinotevera:

1. NBR

Kudzivirira mafuta zvakanyanya, kunodzivirira kupera zvakanyanya, kunodzivirira kupisa zvakanaka, kunamatira kwakasimba. Zvakashata zvacho zvinosanganisira kudzivirira kupisa kwakaderera, kudzivirira ozone zvishoma, hunyanzvi hwemagetsi husina kunaka, uye kusimba kwakaderera zvishoma.

2. EPDM

Chinhu chinonyanya kukosha cheEPDM ndechekudzivirira kwayo oxidation, ozone resistance uye corrosion. Sezvo EPDM iri yemhuri yepolyolefin, ine hunhu hwakanaka hwe vulcanization.

3. PTFE

PTFE ine simba guru rekudzivirira makemikari, inodzivirira mafuta mazhinji uye zvinonyungudutsa (kunze kwemaketone nemaesters), inodzivirira mamiriro ekunze akanaka uye inodzivirira ozone, asi inodzivirira kutonhora zvakanyanya.

4. Simbi yakakandwa

Cherechedza: Simbi inoshandiswa pakupisa kwemvura, gasi nemafuta.≤100°C uye kumanikidzwa kwezita rekuti≤1.6mpa.

5. Chibage chakavakirwa panickel

Cherechedza: Ma alloys akagadzirwa ne nickel anoshandiswa pamapaipi ane tembiricha ye -70~150°C uye PN yekumanikidzwa kweinjiniya≤20.5mpa.

6. Chiumbwa chemhangura

Chishongo chemhangura chinodzivirira kupera simba uye chakakodzera mapaipi emvura neutsi ane tembiricha≤200℃uye kumanikidzwa kwezita rekuti PN≤1.6mpa.
