Poplar Pine khoom OSB board rau kev tsim kho

OSB yog Oriented strand board, yog kev kho dua tshiab ntawm cov khoom siv particleboard, nws cov khoom siv kho tshuab nrog kev taw qhia, durability, noo noo tsis kam, thiab seem stability dua li cov particleboard zoo tib yam.Nrog rau me me expansion coefficient, tsis muaj distortion, zoo stability, uniform khoom thiab ntsia thawv tuav. kev ua haujlwm siab.

Oriented strand board (OSB), tseem hu ua flakeboard, sterling board thiab qab los noj mov nyob rau hauv Askiv Askiv, yog ib hom engineered ntoo zoo li particle board, tsim los ntawm kev ntxiv cov nplaum thiab ces compressing txheej ntawm ntoo strands (flakes) nyob rau hauv cov kev taw qhia. Nws tau tsim los ntawm Armin Elmendorf hauv California hauv xyoo 1963.

Qhov zoo

1) Kev tsim kho nruj thiab lub zog siab;

2) Tsawg kawg twisting, delamination lossis warping;

3) Cov ntaub ntawv pov thawj dej, zoo ib yam thaum raug rau hauv ib puag ncig ntuj lossis ntub dej;

4) Tsawg formaldehyde emission;

5) Zoo nailing zog, yooj yim rau sawn, nailed, drilled, grooved, planed, ntaub ntawv los yog polished;

7) Zoo kub thiab suab resistant, yooj yim rau coated;

8) Nco ntsoov OSB3 yog siv rau ntawm lub ru tsev tiaj tus, ib yam khoom zoo dua li cov qauv chipboard lossis particleboard.

OSB yog dav siv los ua vaj huam sib luag ntoo rau hauv pem teb (suav nrog subfloors thiab underlays), phab ntsa thiab qab nthab. Nws yog siv rau sab hauv fittings, rooj tog zaum, shuttering thiab ntim thiab kuj nyob rau hauv lub tsim ntawm I-joists, qhov twg nws tsim lub web los yog kev txhawb nqa ntawm ob flanges ntawm cov khoom ntoo. OSB tau raug siv tsis yog rau nws cov khoom siv xwb tab sis kuj rau nws cov txiaj ntsig zoo nkauj, nrog qee tus neeg tsim qauv siv nws los ua cov qauv tsim sab hauv.
