Pulogalamu ya OSB
Oriented strand board (OSB) ndi mtundu wa matabwa opangidwa ngati tinthu tating'onoting'ono, opangidwa powonjezera zomatira kenako ndikumangirira zigawo zamitengo yamitengo (flakes) molunjika.
OSB ndi chinthu chomwe chili ndi makina abwino omwe amawapangitsa kukhala oyenera kugwiritsa ntchito zonyamula katundu pomanga.Tsopano ndiyotchuka kwambiri kuposa plywood, ikulamulira 66% ya msika wamapangidwe.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ngati zokhotakhota m'makoma, pansi, ndi padenga.Kwa kunja kwa khoma ntchito, mapanelo zilipo ndi kuwala-chotchinga wosanjikiza laminated mbali imodzi;izi zimathandizira kuyika ndikuwonjezera magwiridwe antchito a envelopu yomanga.
Mankhwala a phenol-formaldehyde amaonedwa kuti alibe zoopsa.Mitundu yatsopano ya OSB imagwiritsa ntchito utomoni wa isocyanate womwe ulibe formaldehyde ndipo umawonedwa ngati wosasunthika ukachiritsidwa.Magulu ochita zamalonda amatsimikizira kuti mpweya wa formaldehyde wochokera ku North America OSB "ndiwopanda pake kapena kulibe".
Ubwino wa OSB board
1) Kumanga kolimba komanso mphamvu yayikulu
2) Pang'ono kupotoza, decontamination kapena warping
3) Palibe chovunda kapena chowola, cholimba motsutsana ndi dzimbiri ndi moto
4) Chitsimikizo cha madzi, chokhazikika chikawonekera mu chilengedwe kapena chonyowa
5) Kutulutsa kochepa kwa formaldehyde
6) Mphamvu yabwino yokhomerera, yosavuta kuchekedwa, kukhomeredwa, kubowola, kupukuta, kukulunga, kupakidwa kapena kupukutidwa.
7) Kutentha kwabwino komanso kusamva mawu, kosavuta kutikita
