Kumaha plywood dijieun? Naon ari lapis?

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

Kumaha carana ngadamel triplek?
Plywood making Plywood processing technology:

Téknologi ngolah triplek:

Dina prosés ngahasilkeun, motong log, peeling, garing, penanganan, pencét panas, ujung trimming, Sanding mangaruhan wastage nu. Wastage nyaéta sésa-sésa ngolah (materiality) jeung nyusut (immateriality). Wastage kai aya hubunganana sareng bahan, spésifikasi log, kamampuan alat, téknologi sareng spésifikasi produksi.

1) Log debarking:

Log debarker:

Biasana panjang log impor langkung ti 6 méter. Motong nurutkeun téhnologi diperlukeun panjang sarta kualitas. Panjang motong kedah panjang produk nambahkeun sésa-sésa. Contona, produk 1220mm * 2440mm, motong panjangna biasana 2600mm atanapi 1300mm. panjang log, camber na demerit mangaruhan kaluaran triplek langsung. Sésa-sésa potongan kai leutik, truncations, sawdust, tec. Babandingan runtah motong log nyaéta 3% -10%.

2) Veneer peeling:

Peeling mangrupikeun prosés ngahasilkeun lapis anu paling populér. Balik ketebalan veneer nyaeta ngeunaan 0.6mm, inti veneer sarta ketebalan veneer puseur nyaeta ngeunaan 1.8mm.

3) Pengeringan:

Veneer téh beueus. eta kudu garing nurutkeun sarat téhnologi. Sanggeus garing, éta bakal ngaleutikan. Dimensi bakal jadi leutik. Panjang veneer, lebar, ketebalan bakal ngaleutikan. Ngaleutikan wastes patali jeung bahan kai, Uap ngandung, ketebalan veneer. Ngaleutikan wastes nyaéta 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) Penanganan Veneer:

Penanganan kaasup motong, nempatkeun veneer babarengan jeung mending. Potong veneer zonal kana spésifikasi veneer atawa ukuran ditangtoskeun nu bisa nunda babarengan. Veneer zonal sempit tiasa dihijikeun kana hiji veneer. Veneer kalayan demerit tiasa dilereskeun janten mumpuni. Wastage dina bagian ieu patali jeung bahan log, kualitas veneer peeled, kualitas garing, sarta skill operasi worker. Babandingan runtah nyaéta 4% -16%. Impor veneer processing ratio wastage triplek nyaeta 2% -11%.

Veneer ngumpul garis atawa leungeun ngumpul

5) Pencét tiis:

The tiis pencét mesin dasar pikeun pabrik lapis. mesin ieu disebut oge pre-pencét. The veneer sanggeus glued tur ngumpul, mimitina eta bakal kabentuk dina panle kosong ku pencét tiis. Teras éta bakal ditransfer ku forklift ka pencét panas.

6) Pencét panas:

Veneer jadi glued jeung tumpuk, teras lem babarengan dina suhu set jeung tekanan ku pencét panas. Salaku suhu veneer sarta Uap ngandung parobahan, veneer bakal ngaleutikan. Ngaleutikan wastes patali jeung suhu, tekanan, waktu pencét panas, bahan kai, Uap ngandung, ratio wastage nyaeta 3% -8%

7) Pemotongan tepi:

Trimming ujung flank triplek ti pencét panas kana papan lapis mumpuni. Tetep aya hubunganana sareng sésa-sésa prosés sareng dimensi produk. Produksi leuwih badag, wastes leuwih leutik. Babandingan runtah nyaéta 6%-9%

8) Ngamplas

Sanding permukaan triplek sangkan eta alus. Runtah nyaéta bubuk. Kualitas Veneer alus, sanding kirang. Babandingan runtah nyaéta 2%-6%

9) Gudang:

Lapis dibungkus dina palletize atanapi di bulk

(10) Laminating with veneer, melamine paper, membrane paper etc.
