Nws raug nquahu kom siv cov ntaub ntawv peb no rau cov rooj sab nraum zoov thiab cov rooj zaum sab nraum zoov. Koj tsis tas yuav txhawj txog cua thiab hnub nyob rau hauv kev siv sab nraum zoov.
1 txhuas rooj tog.
Cov ncej dav dav yog aluminoy alloy, tsim nyog xaiv cov txheej txheem txhuas alloy uas cov khoom siv dej tsis zoo rau cov nag los nag rau cov nag.
2 Rattan rooj tog.
Qhov tseeb cov rooj tog zaum tseem ceeb yog lub luag haujlwm rau cov khoom lag luam tawm suab, cov khoom siv raw yog qhov tsawg. Yog li sab nraum zoov tsim nyog xaiv PE cov pas nrig, du thiab huab cua tsis kam, ove {{
3 Nrum Cov Rooj Tog Zaum.
Nws tau muab faib ua xuab zeb moul pwm casting thiab tuag casting. Xuab zeb casting muaj qhov sib luag saum npoo av, muaj lub zog tsawg thiab hardness. Tuag cov khoom lag luam casting muaj qhov chaw siab siab, tsis muaj porosage thiab shrinkage tsis xws luag, du saum npoo, lub zog yog 25 ~ 30% ntawm cov xuab zeb nrum aluminium. Yog li cov neeg tau txais kev pab yog nyob rau hauv cov rooj tog zaum uas siv sab nraum zoov, tau zoo dua xaiv lub rooj tog sib tw uas tuag casting cov ntaub ntawv.
