Plywood is a typical artificial board. It is called plywood abroad, also called multi-layer board. It has a typical odd-numbered layered structure. Each layer is superimposed perpendicular to each other.

This unique processing method creates structures that balance strength, stability and economy. Plywood does not constantly shrink and expand, deforming like solid wood. Plywood is generally from 3 to 17 layers. Generally speaking, the more layers of the same material, the better the plywood.

The quality of plywood depends on the material. Some are cork, such as pine, poplar, etc. The price of hardwood is higher than that of cork. There are also positive and negative differences between plywood, and the front is generally measured according to flatness and smoothness. There is also a side view of whether the layers are symmetrical, flat, and whether there are holes.

Plywood is a board that woodworking enthusiasts like very much, especially high-grade imported boards, which are called marine boards in the industry. In fact, in recent years, the production process of domestic plywood has been greatly improved, and the processed plywood is no worse than imported plywood, whether it is environmental protection or quality. aspect. The formaldehyde content of the glue used has reached and exceeded the European standard

Theknoloji ea ho lokisa plywood:

Ts'ebetsong ea tlhahiso, ho rema lifate, ho ebola, ho omella, ho tšoara, ho hatisa ho chesang, ho fokotsa moeli, ho senya lehlabathe ho ama tšenyo. Tšenyo ke mesaletsa ea ts'ebetso (material) le ho fokotseha (ho se be le 'mele). Ho senyeha ha lehong ho amana le thepa, litlhaloso tsa log, bokhoni ba lisebelisoa, theknoloji le tlhahiso ea tlhahiso.

1) Ho tlosoa ha li-log:

Hangata bolelele ba lintlha tse tsoang kantle ho naha bo feta 6 metres. Ho khaola ho ea ka theknoloji ho hlokehang bolelele le boleng. The ho itšeha bolelele e lokela ho ba sehlahisoa bolelele eketsa mesaletsa. Ka mohlala, sehlahisoa ke 1220mm * 2440mm, bolelele ba ho itšeha hangata ke 2600mm kapa 1300mm. bolelele ba log, camber le demerit li ama tlhahiso ea plywood ka kotloloho. Mesala ke likotoana tse nyane tsa lehong, li-truncations, sawdust, tec. Karo-karolelano ea tšenyo ea li-log ke 3% -10%.

2) Ho hloekisa Veneer:

Peeling ke mokhoa o tsebahalang haholo oa ho etsa plywood. Botenya ba mokokotlo oa mokokotlo bo ka ba 0.6mm, botenya ba mantlha le botenya bo ka bang 1.8mm.

3) Ho omisa:

Veneer e mongobo. e lokela ho omisoa ho ea ka tlhokahalo ea theknoloji. Ka mor'a ho omisa, e tla fokotseha. Dimension e tla ba nyane. Bolelele ba Veneer, bophara, botenya bo tla fokotseha. Ho senyeha ho amana le thepa ea lehong, mongobo o nang le, botenya ba veneer. Ho senyeha ha sekhahla ke 4% -10%.

1.Steel Tube drying (The most economic type dryer,but capacity is less)

2.Solid hot platen press drier ( If your board is not flat you can choose hot platen solid press dryer.)

3.Core Veneer Continuous roller dryer ( If your capacity is bigger than 50cbm per day, you can choose roller dryer. )

4) Ho sebetsana le Veneer:

Ho sebetsana ho kenyelletsa ho itšeha, ho kopanya veneer le ho lokisa. Khaola zonal veneer ka veneer e khethehileng kapa boholo bo nepahetseng bo ka kopanngoang. Narrow zonal veneer e ka kopanngoa hore e be veneer e le 'ngoe. Veneer e nang le demerit e ka lokisoa hore e tšoanelehe. Tšenyo karolong ena e amanang le thepa ea log, boleng ba veneer e peeled, boleng bo omisitsoeng, le tsebo ea ts'ebetso ea basebetsi. Karolelano ea litšila ke 4% -16%. Karo-karolelano ea ho senyeha ha plywood ea ho kenya lihlahisoa tsa veneer ke 2% -11%.

Mohatsela o batang mochine oa motheo bakeng sa semela sa plywood. Mochine ona o boetse o bitsoa pre-press. Veneer ka mor'a hore e khomaretsoe le ho kopana, pele e tla thehoa ka paneng e se nang letho ka mochine oa khatiso o batang. Joale e tla fetisetsoa ka forklift mochine oa khatiso o chesang.

6) Tobetsa e chesang:

Veneer e khomaretsoe ebe e phutheloa, ebe e khomarela tlas'a mocheso o behiloeng le khatello ka mochine o chesang. Ha mocheso oa veneer le mongobo o nang le liphetoho, veneer e tla fokotseha. Ho senyeha ho amana le mocheso, khatello, nako ea khatiso e chesang, thepa ea lehong, mongobo o nang le, tekanyo ea litšila ke 3% -8%

7) Ho fokotsa moeli:

Ho fokotsa moeli oa plywood flank ho tloha mochine oa khatiso o chesang ho ea ho boto ea plywood e tšoanelehang. Mesala e amanang le mesaletsa ea ts'ebetso le boholo ba sehlahisoa. Tlhahiso e kholoanyane, tšenyo e nyane. Karolelano ea litšila ke 6% -9%

8) Sanding

Sanding plywood bokaholimo ho etsa hore e be ntle. Tšenyo ke phofo. Boleng ba Veneer bo botle, lehlabathe le fokola. Karolelano ea litšila ke 2% -6%
