Plywood ndeye matatu-layer kana akawanda-layer board-senge zvinhu izvo zvinogadzirwa nezvikamu zvehuni zvinopepetwa kuita maveneers kana kuchekwa muhuni dzakatetepa, wozonamirwa nemanamira.Kazhinji, mavheti ane nhamba-asinganzwisisike anoshandiswa, uye ari pedyo akaturikidzana evhavha anoshandiswa.Iyo fiber nzira dzakanamirwa perpendicular kune mumwe nemumwe.
Plywood ndechimwe chezvinhu zvinowanzo shandiswa kugadzira fenicha, uye ndeimwe yemabhodhi makuru matatu emapuranga-akavakirwa mapaneru.Inogona zvakare kushandiswa kune ndege, ngarava, zvitima, mota, zvivakwa uye mabhokisi ekurongedza.Boka remavheiri rinowanzounganidzwa uye rinonamirwa pamwe chete maererano negwara rehuni tsanga yezvikamu zviri pedyo perpendicular kune imwe neimwe.Kazhinji, iyo yepamusoro bhodhi uye yemukati layer bhodhi inorongedzerwa symmetrically pamativi ese epakati layer kana musimboti.Iyo slab yakagadzirwa neveneer mushure mekunamatira ndeye criss-yakayambuka maererano nekutungamira kwehuni yehuni, uye inomanikidzwa pasi pekupisa kana kusapisa.Huwandu hwemitsara kazhinji inhamba isinganzwisisike, uye mashoma ane kunyange manhamba.Musiyano wezvinhu zvemuviri uye zvemakina mune yakatwasuka uye yakachinjika nzira idiki.Mhando dzinowanzo shandiswa dzeplywood ndeye matatu-ply board, mashanu-ply board zvichingodaro.Plywood inogona kuvandudza kushandiswa kwehuni uye inzira huru yekuchengetedza huni.
Kuti uvandudze maitiro anisotropic ehuni hwechisikigo zvakanyanya sezvinobvira, kuitira kuti zvinhu zveplywood zvive yunifomu uye chimiro chigadzikane, chimiro cheplywood yakawanda chinofanira kuenderana nemitemo miviri inokosha: imwe inoenderana;imwe yacho ndeyokuti mafiibhi ezvikamu zviri pedyo zveveneer ari perpendicular kune mumwe nemumwe.Nheyo yekufananidza ndeyekuda kuti mavheji pamativi ese epakati pepuranga symmetrical yeplywood inofanirwa kuve yakaenzana kune mumwe nemumwe zvisinei nemhando yehuni, ukobvu hwevheji, huwandu hwezvikamu, kutungamira kwehuni. fiber, uye hunyoro hwemukati.Mune plywood imwechete, mavheji emhando imwe chete uye ukobvu anogona kushandiswa, kana mavheti emhando dzakasiyana uye ukobvu anogona kushandiswa;zvisinei, chero maviri akaturikidzana evhavha ane symmetric kune imwe neimwe kumativi ese e symmetrical yepakati ndege inofanira kuva nemhando imwechete uye ukobvu.Kumeso uye kumashure zvikwangwani hazvibvumirwi kuva zvemhando imwe chete yemiti.
Kuita kuti chimiro cheplywood chisangane nepamusoro pemitemo miviri inokosha panguva imwe chete, nhamba yezvikamu zvayo inofanira kunge isinganzwisisiki.Nokudaro, plywood inowanzoitwa muzvikamu zvisinganzwisisiki-nhamba dzakadai sezvikamu zvitatu, zvishanu zvishanu, uye zvinomwe.Mazita ega ega mapuranga eplywood ndeaya: iyo yekumusoro veneer inonzi iyo yepamusoro bhodhi, mukati memukati inonzi core board;bhodhi repamberi rinonzi bhodhi, uye bhodhi rekumashure rinonzi bhodhi rekumashure;mu core board, iyo fiber direction inofanana nebhodhi Inonzi refu core board kana medium board.Paunenge uchigadzira cavity deck slabs, kumberi uye kumashure mapaneru anofanirwa kutarisana zvakasimba kunze.
