Ua ntej txau, qhov saum npoo ntawm cov kav hlau ductileyuav tsum qhuav thiab tsis muaj xeb, cov khoom me me uas txuas nrog, roj, thiab lwm yam khoom txawv teb chaws. Tsis zoo li cov kav dej SML, cov kav dej hlau ductile tsis xav tau kev kho ua ntej xuab zeb vim yog cov khoom siv ntawm cov khoom siv. Cov kav dej hlau ductile, los ntawm cov txheej txheem spheroidization uas faib cov graphite hauv cov duab kheej kheej, muaj cov khoom siv kho tshuab zoo heev, nrog lub zog tensile tshaj 420 MPa thiab elongation ntawm 7% thiab 10%, zoo dua li cov kav dej hlau cam khwb cia. Cov qauv no muab kev tiv thaiv corrosion zoo dua, tshwj xeeb tshaj yog tom qab siv cov txheej zinc (> 130 g / m²) thiab cov tshuaj epoxy resin tiav, tsim kom muaj lub kaw lus tiv thaiv ob npaug uas tshem tawm qhov xav tau sandblasting.
Lub qhov (socket) ntawm cov yeeb nkab hlau ductile yog coated nrog zinc tsuag thiab asphalt, thiab yuav tsum dhau daim ntawv pov thawj tsis muaj tshuaj lom. Cov qauv tiv thaiv tag nrho ntawm cov yeeb nkab yog ib txheej galvanized nrog ib txheej tiav, raws li nram no:
- Txheej Zinc: Cov lus qhia dav dav yog 130g / m² thiab 200g / m², nrog rau cov ntsiab lus zinc ntawm 99.9%. Cov txheej txheem zinc-aluminium alloy muab kev ua haujlwm ruaj khov dua thiab kev tiv thaiv xeb zoo dua, nrog rau qhov hnyav txheej txog li 400g / m².
Lus Cim: Cov txheej zinc tuab cuam tshuam rau tus nqi; cov txheej zinc tuab dua ua rau tus nqi nce thiab txhim kho kev tiv thaiv xeb.
- Cov txheej txheem tiav: Feem ntau suav nrog asphalt thiab cov khoom siv hluavtaws.
Feem ntau, cov xim pleev asphalt tuab li ntawm 70µm (feem ntau cov xim pleev asphalt yog qhia los ntawm qhov tuab es tsis yog qhov hnyav ib cheeb tsam).
Cov hom tshuaj pleev xim rau sab saud uas siv ntau yog PU (polyurethane) thiab PE (polyethylene).
SML yeeb nkab hlau cam khwb cia, yeeb nkab hlau ductile txheej, yeeb nkab hlau ductile txheej cement, PU txheej ductile yeeb nkab hlau, qhov (socket) ductile yeeb nkab hlau
