Nzira dzakasiyana-siyana dzekuziva rabha

1. Kuramba bvunzo yekuwedzera huremu hwepakati

Chigadzirwa chapera chinogona kutorwa sechiyereso, kunyikwa mune imwe kana akawanda akasarudzwa, kuyerwa mushure mekupisa kwakati uye nguva yakati, uye mhando yezvinhu zvinogona kufungidzirwa zvichienderana nekuchinja kwehuremu uye kuchinja kwekuomarara.

Semuenzaniso, kunyudzwa mumafuta e100 degrees kwemaawa makumi maviri nemana, NBR, fluorine rabha, ECO, CR ine shanduko diki muhunhu nekuomarara, nepo NR, EPDM, SBR inopfuura kaviri muhuremu uye inochinja zvakanyanya mukuomarara, uye kuwedzera kwehuwandu kuri pachena.

2. Muedzo wekukwegura kwemhepo inopisa

Tora mienzaniso kubva kuzvigadzirwa zvapera, uzviise mubhokisi rekukwegura kwezuva rimwe chete, uye tarisa chiitiko ichi mushure mekukwegura. Kukwegura zvishoma nezvishoma kunogona kuwedzerwa zvishoma nezvishoma. Semuenzaniso, CR, NR, uye SBR zvichave zvisina kusimba pa150 degrees, nepo NBR EPDM ichiri isina kusimba. Kana tembiricha yakwira kusvika 180 degrees, NBR yakajairika ichave isina kusimba; uye HNBR ichave isina kusimbawo pa230 degrees, uye fluorine rabha nesilicone zvichiri ne elasticity yakanaka.

3. Nzira yekupisa

Tora chidimbu chidiki wochipisa mumhepo. cherechedza chiitiko ichi.

Kazhinji, rabha yefluorine, CR, CSM haina moto, uye kunyangwe murazvo uri kutsva, diki zvikuru pane NR neEPDM. Ehe, kana tikanyatsoongorora, mamiriro ekutsva, ruvara, uye hwema zvinotipawo ruzivo rwakawanda. Semuenzaniso, kana NBR/PVC ikasanganiswa neglue, kana paine chinobva moto, moto unopfachukira uye unoita semvura. Zvinofanira kucherechedzwa kuti dzimwe nguva glue inodzivirira moto asi isina halogen inozvidzimawo yoga kubva mumoto, izvo zvinofanira kufungidzirwa nedzimwe nzira.

4. Kuyera simba renyika rakaita segiravhiti

Shandisa chikero chemagetsi kana chiyero chekuongorora, chakarurama kusvika 0.01 gram, pamwe negirazi remvura nebvudzi.

Kazhinji, rabha yefluorine ine simba guru rekukura, riri pamusoro pe1.8, uye zvigadzirwa zvakawanda zveCR ECO zvine huwandu hwakakura huri pamusoro pe1.3. Maglue aya anogona kufungwa nezvawo.

5. Nzira yekupisa yakaderera

Tora sampuro kubva muchigadzirwa chapera woshandisa aizi yakaoma nedoro kuti ugadzire nzvimbo yakakodzera yekupisa. Nyika sampuro munzvimbo ine tembiricha yakaderera kwemaminitsi 2-5, inzwa kupfava nekuoma kwayo patembiricha yakasarudzwa. Semuenzaniso, pa-40 degrees, silica gel nefluorine rabha zvakafanana zvinoenzaniswa, uye silica gel inonyorova.
