Parizvino, zvinhu zvepombi zvinoshandiswa mumotokari zvinogona kukamurwa muzvikamu zvitatu: pombi yenylon, pombi yerabha uye pombi yesimbi.Machubhu anowanzo shandiswa naironi anonyanya PA6, PA11 uye PA12.Zvinhu zvitatu izvi zvakabatanidzwa zvinonzi aliphatic Pa. PA6 uye PA12 ndeye ring kuvhura polymerization uye PA11 ndeye condensation polymerization.
1. Zvakanakirapombi yenaironindeaya anotevera: ▼ yakanakisa mafuta kuramba (peturu, dhiziri), mafuta ekuzora uye girizi, uye makemikari kuramba.▼ yakaderera tembiricha inokanganisa kuramba: PA11 inogona kumira yakadzika tembiricha maitiro e - 50 ℃ uye PA12 inogona kumira yakadzika tembiricha maitiro e - 40 ℃.▼ yakafara application tembiricha renji: tembiricha yekushandisa yePA11 iri - 40 ~ 125 ℃, uye chinzvimbo chePA12 chiri - 40 ~ 105 ℃.Mushure mebvunzo yekuchembera pa125 ℃, 1000h, 150 ℃ uye 16h, PA11 pombi ine yakanaka yakaderera-tembiricha maitiro ekuita.▼ kushorwa neokisijeni uye zinc munyu corrosion: kupikisa 50% zinc chloride mhinduro kune anopfuura 200H.▼ inopikisa bhatiri acid uye ozone.▼ chinhu chekuzvizora chega chine vibration kuramba, kupfeka kuramba, kuneta kuramba uye yakaderera friction coefficient.▼ UV kuramba uye kuchembera kwemuchadenga: kupikisa kweUV kwemavara echisikigo PA11 kunogona kushandiswa kwemakore 2.3-7.6 zvichienderana nematunhu akasiyana;Iyo anti ultraviolet kugona kwepa11 dema yakawedzera kakapetwa kana mushure mekuwedzera anti ultraviolet inonwisa.
Magadzirirwo epombi naironi ndeiyi: ① extrusion maitiro ② kugadzira maitiro ③ musangano maitiro ④ yekuona maitiro.Kazhinji,pombi yenaironiine mabhenefiti makuru mukuita kana ichienzaniswa nepiipi yesimbi, nepo iri nani mumakemikari ekuora kwekudzivirira uye kupfeka kuramba kana zvichienzaniswapombi yesimbi isina tsvina, iyo inoita basa guru mukuderedza huremu hwemotokari uye mutengo wekugadzira.
2. Kune dzakawandarubber hosezvimiro zvemotokari, uye zvimiro zvekutanga zvinosanganisira zvakajairika mhando, yakasimbiswa mhando uye yakavharwa mhando.
Chimiro cherabha hose parizvino, anonyanya kushandiswa erabha pombi zvinhu pamusika FKM, NBR, Cr, CSM uye eco: ▼ tembiricha yebasa yeFKM (fluororubber) i20 ~ 250 ℃, inonyanya kushandiswa O- rin'i, chisimbiso chemafuta, musara wemukati wehose yemafutanezvimwe zvigadzirwa zvekuvharisa.▼ tembiricha yebasa yeNBR (nitrile rubber) ndeye 30 ~ 100 ℃, iyo inonyanya kushandiswa kune rabha hose, yekuisa chisimbiso mhete uye chisimbiso chemafuta.▼ tembiricha yebasa yeCr (chloroprene rubber) ndeye 45 ~ 100 ℃, inonyanya kushandiswa tepi, hose, wire coating, rubber plate gasket 'guruva chivharo, etc. ~ 120 ℃, iyo inonyanya kushandiswa matai, tepi, spark plug sheath, waya, magetsi emagetsi, O-mhete, musuwo uye mahwindo ekuvhara machira, nezvimwewo ▼ tembiricha yebasa re eco (Chloroether rabha) i40 ~ 140 ℃, iyo inonyanya kushandiswa kupisa mhete, diaphragm, shock pad, rabha hose, nezvimwe.
3. Serudzi rwepombi yakaoma,pombi yesimbiine zvakanakira uremu hunorema, mutengo wakakwira uye kutsemuka kuri nyore.Naizvozvo, akawanda uye akawanda emotokari mabhizinesi anosarudza kurega kushandiswa kwesimbi pombi.Parizvino, simbi yealuminium pombi inonyanya kukodzera kumhepo inogadzirisa hurongwa.Nekudaro, kusimba kwekusimba, kuputika kumanikidza uye kuramba kuchembera kwepombi dzesimbi zviri nani pane izvo zvepombi dzenaironi nemapombi erabha.
