Lub zog siab thiab kev ncaj ncees ntawm cov hlau, nrog rau nws lub peev xwm los tiv thaiv huab cua, txo qhov kev pheej hmoo ntawm kev xau lossis kev ua tsis tiav uas tuaj yeem ua rau tawg lossis tso tawm cov khoom phom sij. Los ntawm kev siv cov hlab ntsha uas tsim nyog thiab ua raws li cov txheej txheem nruj thiab tshuaj xyuas, kev lag luam tuaj yeem tswj tau qhov chaw ua haujlwm nyab xeeb thiab tiv thaiv kev puas tsuaj.
Q: Dab tsi yog cov khoom siv tshaj plaws hauv cov hlab ntsha siab?
A: carbon hlau
Cov pa roj carbon steel feem ntau yog siv los ua cov khoom siv rau cov hlab ntsha siab, thiab yog vim li cas. Nws tiv taus melting, tawg, thiab lwm yam kev puas tsuaj. Cov pa roj carbon steel tiv thaiv kev poob siab thiab kev co thiab muaj lub zog tensile siab.
Q: Kuv yuav xaiv cov khoom siv lub nkoj siab li cas?
A: Cov qib stainless hlau muaj qhov zoo tshaj plaws corrosion-cov khoom tiv taus thiab tiv taus ntau yam tshuaj. Nws yog kev lag luam thiab zoo tagnrho rau kev siv nyob rau hauv qhov kub thiab txias. Titanium ntau yam khoom ua rau nws tsim nyog siv rau hauv lub nkoj siab.
