DuctileHlau cam khwb ciaCov yeeb nkab (DCIP) yog ib hom khoom siv uas muaj zog thiab siv tau ntau yamyeeb nkabSiv dav hauv cov dej thiab cov dej khib nyiab. Nws yog ua los ntawm cov hlau ductile, ib yam khoom uas paub txog nws lub zog, kev ruaj khov, thiab kev ywj pheej piv rau cov hlau cam khwb cia ib txwm muaj. Hom yeeb nkab no muab cov txiaj ntsig ntawm kev tiv thaiv xeb ntawm cov hlau cam khwb cia nrog kev txhim kho lub zog tensile thiab kev ywj pheej, ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov haujlwm tsim kho vaj tse niaj hnub.

Cov Nta Tseem Ceeb:

1. Cov Khoom Siv Muaj pes tsawg leeg:

• Cov hlau cam khwb cia uas ductile yog tsim los ntawm kev ntxiv magnesium rau cov hlau uas yaj, uas hloov cov qauv graphite mus rau hauv daim ntawv kheej kheej (nodular).
• Qhov kev hloov pauv ntawm cov qauv no ua rau cov khoom siv kho tshuab zoo dua.

2. Lub zog thiab kev ywj pheej:

• Cov kav dej hlau uas ua los ntawm cov hlau nplaum zoo tuaj yeem tiv taus cov kev nyuaj siab sab hauv thiab sab nraud thiab tsis tshua muaj kev tawg thaum muaj kev thauj khoom vim lawv yooj ywm.

3. Kev Tiv Thaiv Kev Xeb:

• Feem ntau coated nrog cov ntaub ntawv xws li cement mortar, epoxy, lossis polyethylene kom tiv taus corrosion thiab xyuas kom meej lub neej ntev, tshwj xeeb tshaj yog nyob rau hauv cov av hnyav.

4. Cov Ntawv Thov Dav Dav:

• Feem ntau siv rau kev faib dej, cov kav dej phwj tuaj, cov kav roj, thiab kev thauj mus los ntawm cov kua dej hauv kev lag luam.

5. Hom Sib Koom Tes:

• Muaj ntau yam kev xaiv sib koom ua ke, suav nrog cov pob qij txha thawb-rau, cov pob qij txha kho tshuab, thiab cov pob qij txha flanged, uas ua rau yooj yim rau kev teeb tsa thiab hloov kho rau ntau lub tshuab sib txawv.

6. Lub neej ntev:

• Nrog kev teeb tsa thiab kev txij nkawm kom zoo, cov hlau cam khwb cia ductileCov kav dej tuaj yeem kav ntev tshaj 100 xyoo, ua rau lawv yog qhov kev xaiv pheej yig rau cov haujlwm mus sij hawm ntev.
