Substrate thlan & Surface buatsaih dan
Technology wood veneer siamnaah chuan substrate buatsaih hi foundation pawimawh tak a ni a, chu chuan bonding strength, surface appearance, leh overall product performance te direct-in a nghawng a ni. Engineered veneer materials hi a tlangpuiin a hring (0.10mm–0.50mm) a nih avangin, uluk taka enkawl loh chuan lamination hnuah substrate chhiatna eng pawh a lang thei.
He thuziak hian veneering process hmasa ber: substrate thlan leh surface buatsaih dan a tarlang a ni.
1. Substrate thlan dan tur tehfung
Substrate thlan dik hian structural stability leh bonding rintlakna a tichiang a ni.
1.1 Bonding chakna mamawh
Substrate hian national bonding strength standard a tlin tur a ni a, a shear strength tlem ber chu7 MPa a ni.
A zalen tur a ni:
Delamination tih a ni
Blistering a awm
Edge tihchhiat a ni
Cracks emaw warping na tak emaw a awm thei
Board chunglam chu a hrual a, a inmil tur a ni a, bawlhhlawh, oil stain, glue mark, leh deep scratches awm lovin.
1.2 Tui awm zat control
Substrate moisture content hi a tlangpuiin a hnuaiah hian control tur a ni14%.
Moisture tam lutuk hian hot pressing laiin localized bubbling a thlen thei a, adhesion quality a nghawng thei bawk.
1.3 Thickness tuar theihna
Thickness deviation chu a tam lo tur a ni±1%uniform pressing leh veneer bonding a awm theih nan.
1.4 Thil chhiatna enkawl dan
Substrates rawng danglamna nasa tak nei, knot clusters, emaw surface defect dang nei tan chuan batch-based classification leh treatment hi product appearance mumal tak vawng reng turin a tha.
2. Substrate Sanding tih a ni
Veneering hmain substrate thlan bikte chu surface sanding (single-side sanding) an nei a, chu chuan:
Uniform thickness a ni
Surface flatness tihchangtlun
Adhesive bonding performance tihchangtlun a ni
Thickness tolerance hi a chhungah control tur a ni±0.10 mm a nisanding hnuah.
Sanding dust leh thing chi hrang hrang zawng zawng chu a hnuaia process step hmain uluk taka paih vek tur a ni.
3. Substrate chunglam enkawl dan
Technology veneer sheet hi natural wood emaw fast{0}}growing species atanga slicing process hmanga siam a ni. An structure te tak te avang hian substrate defect te chu tha takin an thup thei lo.
Substrate chunglam chu uluk taka enkawl a nih loh chuan:
A rawng hrang hrang
Knot pattern hrang hrang a awm
Surface a famkim lohna
hot pressing hnuah a lang thei a, product grade leh surface aesthetics pahnih a nghawng tha lo hle.
Chuvangin, substrate surface treatment hi premium veneer performance neih theihna tura hmalakna pawimawh tak a ni.
3.1 Substrate hman dan tlangpui
Entirna:
1220mm × 2440mm × 3mm poplar plywood a ni a, natural knot features a awm bawk.
3.2 Veneer Sheet chungchang sawifiahna
Entirna:
Engineered veneer sheet lian leh te: 2500mm × 640mm × 0.50mm a ni.
3.3 Thing Filler hman dan (Base Treatment) 1.1.
Wood filler (wood putty emaw base leveling compound tia hriat bawk) hi surface imperfections thup nan leh bonding performance tichak turin an hmang thin.
Function hrang hrangte chu:
Substrate chhiatna thup
Surface smoothness tihchangtlun
Structural stability tihpun
Overall finishing quality tihchangtlun
Mixing ratio tlangpui chu:
Yellow component 1 part : Var component 2 parts a awm bawk
A man zat tur zat: 5.5 RMB/kg.
3.4 Thil hmanrua siam dan
Base treatment hmanna atan hian roller coating machine pathum- awlsam zawk hman a ni tlangpui.
Key configuration-ah hian:
Roller chunglam: Rubber khauh tak (HB40–50), a sei zawng chu. 210mm vel a ni
Middle roller: Stainless steel (chrome-plated), a sei zawng chu. 120mm vel a ni
Roller hnuai lam: Stainless steel (chrome-plated), a sei zawng chu. 210mm vel a ni
Machine hi threaded embossing roller tel lovin a thawk a, coating pawh a smooth leh even a tichiang a ni.

3.5.1 Machine siam dan tur
Coating machine chu start la, wood filler buatsaih chu upper rollers inkar groove-ah hnawih rawh.
Rotation speed rawtna chu:60–80 r/min a ni.
3.5.2 Coating Control dan tur
Substrate sir khatah filler layer te tak te leh uniform tak hmangin hnawih la.
Dilna rate rawtna chu:
