Re boetse re entse thepa ea ka tlung e entsoeng ka thepa e 'ngoe ntle le likutu, ho kenyeletsoa plywood le liboto tsa menoana, empa hona joale re etsa plywood feela ka lisebelisoa tse latelang: E0, E1, le E2 kaofela li bua ka litekanyetso tsa tikoloho tse nang le maemo a fokolang a tokollo ea formaldehyde.E2（≤ 5.0mg/L), E1 (≤1.5mg/L), E0 (≤0.5mg/L)
E1 ke tlhokahalo ea mantlha ea plywood ea khoebo ho fihlela maemo a bophelo.Ka tlhokahalo e ntseng e eketseha ea lihlahisoa,
Mapolanka a tiileng a mapolanka a plywood a ntse a eketsa boemo ba ts'ireletso ea tikoloho ho E0.
Mokhoa oa ho khetholla boleng ba plywood, e ka khetholloa ho lintlha tse latelang:
Taba ea pele, matla a tlamahano a molemo;Mofuta ofe kapa ofe oa matla a ho khomarela boto o molemo, ho bolelang hore matla a ho khomarela ke ntho e hlokahalang.Taba ea pele, hlokomela hore na ho na le liketsahalo tse hlakileng tsa lera ho pota-pota le hore na ho na le li-bubble holim'a metsi.Taba ea bobeli, ka ho sututsa le ho tobetsa clamp, na u utloa lerata.Ha e le hantle, haeba ho na le lerata, e ka 'na ea se ke ea e-ba ka lebaka la boleng bo tlaase ba sekhomaretsi.E ka 'na ea e-ba ka lebaka la motheo o se nang letho kapa lisebelisoa tse fokolang tse sebelisetsoang boto ea mantlha, empa tsohle li bontša hore boleng ha bo botle.
Ea bobeli, flatness e ntle;Ho tloha ntlheng ena, ho ka bonoa hore thepa ea ka hare ea boto e sebelisoa.Ha re shebile boto, re e tšoara ka matsoho ho utloa hore na ho na le ho se lekane.Haeba ho na le leha e le efe, e bontša lintlha tse peli: ebang bokaholimo ha bo na lehlabathe hantle, kapa boto ea mantlha e entsoe ka lisebelisoa tse futsanehileng, tse batlang li arohane.
Taba ea boraro, ha boto e le botenya, ho ba bonolo ho e bona.Mohlala, plywood ea 18cm ea li-multilayer e entsoe ka ho tobetsa likarolo tse 11 tsa boto ea mantlha.Haeba lera le leng le le leng le entsoe ka thepa e feletseng, lihlopha li hlakile haholo 'me ho ke ke ha e-ba le ketsahalo ea lihlopha tse pota-potileng.Haeba lisebelisoa li sa sebelisoe hantle 'me ho na le lisebelisoa tse ngata tse pshatlehileng, ka lebaka la khatello, lihlopha li tla kopana 'me li thehe ho se lekane ha holimo.
Ea bone, boto e ntle ha e le hantle ha e holofatse;Tekanyo ea deformation e amana haholo-holo le thepa ea sebele ea lehong ka boeona, mongobo oa lona le boemo ba leholimo.Seo re ka se laolang ke mongobo.Hape re ka khetha lehong le nang le deformation e fokolang.
Ea bohlano, hore na botenya bo ka har'a moeli o tloaelehileng;Ka kakaretso, botenya ba liboto tse ntle bo ka har'a mefuta e mengata ea maemo a naha.
Karolo e ka pele ea boto ea menoana e tšoana le ea plywood ea li-multi-layer.Boto ea menoana ke boto e entsoeng ka ho kopanya litšila tse setseng ka mor'a ho lokisa lehong le tala, 'me boto e nang le mefuta e mengata ke lepolanka le sehang boto ea pele ea lepolanka likotoana tse tšesaane ebe e li kopanya.Litheko tsa tsena tse peli li tšoana, empa ka lebaka la khaello ea lera ka boto ea menoana, e na le tšekamelo ea ho senyeha ha e bapisoa le plywood ea li-multi-layer.
Ho sebetsa ha lipoleiti tsa manonyeletso a menoana ha hoa pharalla joalo ka lipoleiti tse ngata.Ka mohlala, haeba likarolo tse ling tse telele li sebelisoa ka lipoleiti tse kopantsoeng tsa menoana, matla a tsona a ho jara moroalo ha a tšoane le a multi layer plywood, 'me a atisa ho petsoha tlas'a tekanyo e itseng ea matla a ka ntle.Hangata liboto tsa menoana li sebelisoa ho etsa liphanele tse kholo tsa mamati le lishelefo.'Me li-plywood tsena tse nang le li-multi-layer le tsona li ka etsoa, ka hona ha se hangata re sebelisang liboto tse kopantsoeng tsa menoana hona joale.
