Kev sib tw thiab kev daws teeb meem rau Wood Railway Sleepers
- Organic Material Vulnerability
Ntoo, yog cov organic, muaj kev cuam tshuam rau kev lwj thiab degradation los ntawm kab tsuag thiab kab mob, ua rau lub neej luv luv rau cov ntoo railway sleepers.
- Anticorrosive kho
Anticorrosive kev kho mob tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm cov ntoo pw tsaug zog, nrog lub sijhawm ntsuas ntawm 13 txog 19 xyoo tom qab kho. Txawm li cas los xij, nce kev thauj mus los, nrawm, thiab thauj khoom tuaj yeem txo qhov no mus rau 8 txog 10 xyoo.
- Tshuaj kho mob
Cov tshuaj siv tshuaj xws li thee tar thiab creosote nyob rau hauv cov roj preservatives feem ntau yog siv los kho cov ntoo pw tsaug zog, nrog sib tov sib piv ntawm 1: 1. Creosote ua raws li cov tshuaj toxicant, thaum thee tar tsim ib txheej tiv thaiv.
