Takagadzirawo fenicha yakagadzirwa nezvimwe zvinhu kunze kwematanda, zvinosanganisira plywood nemapuranga eminwe, asi iye zvino tinongogadzira plywood tichishandisa zvinotevera: E0, E1, uye E2 zvose zvinoreva mazinga ezvakatipoteredza ane mazinga mashoma ekusunungurwa kwe formaldehyde.E2（≤ 5.0mg/L), E1 (≤1.5mg/L), E0 (≤0.5mg/L)
E1 chinhu chakakosha chinodiwa chekutengesa plywood kusangana nemamiriro ekugara.Nekuwedzera kuri kuda kwezvigadzirwa,
Solid wood multi-layer boards plywood iri kuwedzera kuwedzera mazinga ekuchengetedza kwezvakatipoteredza kusvika kuE0.
Nzira yekusiyanisa kunaka kweplywood, inogona kusiyaniswa kubva pane zvinotevera pfungwa:
Kutanga, simba rekubatanidza rakanaka;Chero mhando yebhodhi yekunamatira simba iri nani, zvinoreva kuti simba rekunamatira ndiro rinodiwa.Chekutanga, tarisa kana paine zviri pachena zviri kuitika zvakatenderedza uye kana paine mabubble pamusoro.Kechipiri, nekusundidzira nemaoko uye nekudzvanya iyo clamp, unonzwa chero ruzha.Ehe, kana paine ruzha, zvinogona kunge zvisiri hazvo nekuda kwehurombo hwekunamatira kunaka.Zvinogona kunge zvichikonzerwa nehollow core kana zvinhu zvisina kunaka zvakashandiswa kune core board, asi zvese zvinoratidza kuti mhando haina kunaka.
Chechipiri, flatness yakanaka;Kubva panguva ino, zvinogona kuonekwa kuti zvinhu zvemukati zvebhodhi zvinoshandiswa.Patinenge tichitarisa pabhodhi, tinoibata nemaoko edu kuti tinzwe kana pane kusaenzana.Kana paine, inoratidza mapoinzi maviri: ingave iyo nzvimbo haina kunyatso kucheneswa, kana bhodhi repakati rakagadzirwa nezvinhu zvisina kunaka, izvo zvakapatsanurwa.
Chechitatu, Iyo yakakura bhodhi, zviri nyore kuona.Semuyenzaniso, 18cm multi-layer plywood inogadzirwa nekutsikirira 11 layers yecore board.Kana chidimbu chega chega chakagadzirwa nezvinhu zvose, zvidimbu zvakanyatsojeka uye hapazovi nechiitiko chezvikamu zvakapindirana.Kana zvinhu zvisina kushandiswa zvakanaka uye kune zvakawanda zvakapwanyika zvinhu, nekuda kwekumanikidzwa, zvidimbu zvichapindirana uye zvinoumba kusaenzana kwepamusoro.
Chechina, bhodhi rakanaka harina kukanganisa;Dhigirii re deformation rinonyanya kuenderana nehunhu hwehuni pachayo, hunyoro hwayo, uye mamiriro ekunze.Chatinokwanisa kudzora hunyoro.Tinogonawo kusarudza huni ine zvishoma deformation.
Chechishanu, kana ukobvu huri mukati mechiyero chechiyero;Kazhinji kutaura, ukobvu hwemapuranga akanaka huri mukati mehuwandu hwemitemo yenyika.
Pamberi pechigunwe bhodhi chakafanana neiyo yakawanda-layer plywood.Finger board ibhodhi rinogadzirwa nekunamira tsvina inenge yasara mushure mekugadzira huni mbishi, uye multi-layer board ibhodhi rinocheka bhodhi rekutanga kuita zvidimbu zvitete rozoabatanidza pamwechete.Mitengo yezviviri zvakafanana, asi nekuda kwekushayikwa kwekuiswa mubhodhi remunwe, inonyanya kukonzeresa deformation kana ichienzaniswa neakawanda-layer plywood.
Iko kushanda kwemunwe mahwendefa ejoint haina kuwanda seaya emulti layer plates.Semuyenzaniso, kana zvimwe zvikamu zvakarebesa zvichishandiswa nemaplateti ezvigunwe zvakabatanidzwa, simba ravo rekutakura mutoro harina kunaka sere multi layer plywood, uye rinowanzo putika pasi peimwe dhigirii rekunze kwesimba.Mabhodhi eminwe anowanzo shandiswa kugadzira mapaneru emagonhi makuru nemasherufu.Uye aya akawanda-layer plywood anogona zvakare kugadzirwa, saka isu hatiwanzo shandisa zvigunwe zvekubatanidza mabhodhi izvozvi.
