Njira zingapo zodziwika bwino

1. Kukaniza kwa kulemera kwapakatikati

Chotsirizidwa chimatha kusungidwa, kunyowa mu media umodzi kapena zingapo zosankhidwa, kulemera kwakanthawi, ndipo mtundu wa zinthu zitha kuphatikizidwa molingana ndi kuchuluka kwa kulemera komanso kuwuma kolimba mtima.

For example, immersed in 100 degree oil for 24 hours, NBR, fluorine rubber, ECO, CR has a small change in quality and hardness, while NR, EPDM, SBR more than doubles in weight and changes in hardness greatly, and the volume expansion is obvious.

2. Kuyesa kwa Otentha

Tengani zitsanzo kuchokera ku zinthu zomalizidwazo, ayikeni m'bokosi lokalamba tsiku lina, ndipo saona zodabwitsazi. Kukalamba pang'onopang'ono kumatha kukulira pang'onopang'ono. Mwachitsanzo, Kh, ndi SBRS ikhala yopanda madigiri 150, pomwe NBR EPDM idakali yodziwika bwino. Kutentha kukakwera madigiri 180, anthu wamba Nbr. Ndipo Hnbr idzakhala yopanda malire pa madigiri 230, ndipo silika wa fluorine ndi silika.

3. Njira yoyaka

Tengani zitsanzo zochepa ndikuzitentha mlengalenga. Onani Zochitikazo.

Nthawi zambiri, phraphi ya fluorine, cr, csm ndi opanda moto, ndipo ngakhale ngati lawi likuyaka, ndizocheperako kuposa Elder ndi Epdm. Zachidziwikire, ngati tikuyang'ana kwambiri, mkhalidwe wa kuyamwa, mtundu, ndi kununkhira kumatipatsanso zambiri. Mwachitsanzo, pomwe NBR / PVC imaphatikizidwa ndi guluu, pomwe pali gwero la moto, moto umasilira ndipo akuwoneka ngati madzi. Dziwani kuti nthawi zina guluu ukulu wodziletsa udzadzigwetsanso kumoto, womwe uyenera kusokonezedwanso ndi njira zina.

4. Kuyeta mphamvu yokoka

Gwiritsani ntchito sikelo yamagetsi kapena kusanthula bwino, zolondola ku 0,0 grim, kuphatikiza kapu yamadzi ndi tsitsi.

Nthawi zambiri, mphira wa fluorine uli ndi mphamvu yayikulu kwambiri yokoka, pamwamba pa 1.8, ndipo ambiri a zinthu zambiri, ali ndi gawo lalikulu pamwambapa 1.3. Mabatani awa atha kuganiziridwa.

5. Njira yotentha yotsika

Tengani zitsanzo kuchokera ku chinthu chomalizidwa ndikugwiritsa ntchito ayezi wouma komanso mowa kuti mupange malo oyenera a Crooligenic. Zilowerere chitsanzo chochepa kwambiri kwa mphindi 2-5, mukumva kufewa komanso kuuma pa kutentha kosankhidwa. Mwachitsanzo, madigiri a -40, kutentha kwambiri ndi mafuta kukana mafuta silika gel osakaniza, ndipo silika gel osalala.
