High Quality Ntim Timber Packing LVL

LVL (ntoo feem ntau) muaj qhov txiaj ntsig zoo dua cov tswv cuab steel thaum raug rau qhov chaw corrosive. Cov ntoo thiab cov khoom ntoo muaj peev xwm tiv taus cov kua qaub me me thiab tiv taus ntau dua rau degradation.

Tus cwj pwm ntawm LVL nyob rau hauv ib puag ncig tshuaj yog nyob ntawm ntau yam, suav nrog PH thiab kub. Ntoo tseem ceeb teb los ntawm qhov o, zoo ib yam li cov lus teb ya raws, los yog los ntawm cov tshuaj degradation. Kev puas tsuaj vim o yog qhov tseem ceeb thim rov qab, tab sis tshuaj lom neeg degradation ua rau tawg ntawm cov qauv ntoo thiab tsis yog rov qab.

Cov neeg sawv cev qeb S suav nrog cawv thiab lwm yam tshuaj tiv thaiv kab mob. Cov neeg ua hauj lwm no swell ntoo qhuav ua rau lub zog (thiab khov kho) poob proportional rau qhov o

Cov nyhuv ntawm cov tshuaj ntawm cov ntoo feem ntau yuav phem zuj zus los ntawm kev nthuav tawm lub sijhawm, qhov kub thiab txias, pH siab heev thiab tshuaj lom neeg concentration. Ntoo feem ntau muaj qhov tsis kam tiv thaiv alkalis ntau dua li cov kua qaub. Softwoods (xws li LVL) feem ntau muaj kev tiv thaiv zoo rau cov kua qaub dua li cov ntoo tawv.
