Abiɛsa Layer Density Board Composite ma Ɔpon Frame

Nneɛma abiɛsa-layer density board composite yɛ nhyehyɛe, multi-layer ade a wɔayɛ no pɔtee ama apon frame yɛ. Ɛka mfasoɔ a ɛwɔ density boards so (sɛ nhwɛsoɔ no, ɛgyina pintinn, mfiri a ɛtumi yɛ adwuma) bom berɛ a ɛdi anohyetoɔ a ɛwɔ single-layer boards mu (sɛ nhwɛsoɔ no, nsuo a ɛko tia a ɛnyɛ papa, ahoɔden a ɛnnɔɔso) ho dwuma. Ase hɔ no yɛ ne layer nhyehyɛe, ne su titiriw, ɔkwan a wɔfa so yɛ, mfaso a ɛwɔ so wɔ dwumadie mu, ne nsusuiɛ a wɔakyekyɛ mu kɔ akyiri.

1. Core Layer Nhyehyɛe

Nneɛma a wɔabom ayɛ no yɛ nneɛma abiɛsa a ɛyɛ adwuma, na emu biara di dwuma soronko wɔ ɔpon no nnua no adwumayɛ mu. Wɔde ntama a ɛyɛ den-ahoɔden kɛse, nsu-a ɛko tia (sɛ nhwɛso no, melamine urea-formaldehyde resin, polyurethane adhesive) na ɛkyekyere ntoatoaso no de hwɛ hu sɛ ntama no ntam ayɛ biako.

2. Su Titiriw a Ɛwɔ Hɔ

Wɔayɛ saa ade a wɔabom ayɛ yi sɛnea ɛbɛyɛ a ɛne ahwehwɛde a emu yɛ den a ɛwɔ ɔpon ntama a wɔde di dwuma mu no hyia, na ɛwɔ su ahorow a ɛda nsow a edidi so yi:

Exceptional Dimensional Stability: Nneɛma abiɛsa-layer nhyehyɛe no ma "stress balance"-rigid surface layer ne flexible core layer no siw wɔn ho wɔn ho thermal expansion/contraction ano. Eyi ma twitwiw, mpaapaemu, anaa twitwiw so nyɛ kɛse, mpo wɔ mmeae a ɛhɔ hyew sakra (sɛ nhwɛso no, ɛbɛn mframa a wɔde yɛ ɔhyew) anaasɛ nsu a ɛyɛ nwini (sɛ nhwɛso no, aguaree, adididan).

High Machinability: Layers nyinaa (HDF, MDF, LDF) yɛ pɛ wɔ texture mu (abɔde mu nnua nhama anaa aburow sintɔ biara nni mu). Eyi ma ɛyɛ mmerɛw sɛ wobetu (ma hinge ntokuru), ɔkwan a wɔfa so (ma lock notches), na wotwitwa, na ɛma wohu sɛ ɛne apon nhaban ne afasu hyia pɛpɛɛpɛ.

Adwumayɛ pa a ɛwɔ soro: HDF soro a ɛwɔ soro no wɔ porosity a ɛba fam na ɛyɛ mmerɛw, na ɛma ɛyɛ nea eye ma bonding decorative nneɛma (sɛ nhwɛso no, nnua veneer, PVC film, paint). Ɛsan nso kura nneɛma a wɔde kyekyere nneɛma (nkuruwankuruwa, nnadewa) yiye, na ɛmma hinge anaa ɔpon a wɔde gyina hɔ no ntumi nkɔ baabiara bere a bere kɔ so no.

Ka-Ntu mpɔn: Sɛ wɔde toto nnua a ɛyɛ den anaa HDF apon a ɛyɛ ma ho a, abiɛsa{1}}layer composite no brɛ nneɛma ho ka ase (denam LDF/MDF a wɔde di dwuma wɔ mu layers mu) bere a ɛkura adwumayɛ a wɔde toto ho no mu. Ɛtew nneɛma a wɔsɛe no so nso, efisɛ nhyehyɛe a ɛyɛ pɛ no ma ntwitwiridii a asɛe no so tew.

Nneɛma a Atwa Yɛn Ho Ahyia a Wɔahyɛ So: Density board dodow no ara a ɛwɔ composite no mu no de formaldehyde-formaldehyde a enni mu anaasɛ ɛba fam-formaldehyde adhesives (a ɛne gyinapɛn te sɛ E0, CARB Phase 2 hyia) di dwuma, na ɛma ɛfata sɛ wɔde di dwuma wɔ dan mu (sɛ nhwɛso no, atrae, adwumayɛbea apon) a ɛnyɛ akwahosan ho asiane biara.

3. Nneɛma a Wɔyɛ

Nneɛma abiɛsa-layer density board composite a wɔyɛ ma apon nnua no di adwumayɛ nhyehyɛe a wɔahyɛ da ayɛ, a ɛyɛ adwuma ankasa akyi de hwɛ hu sɛ ɛyɛ pɛpɛɛpɛ:

Nneɛma a Wɔde Siesie:

Twitwa HDF (anim), MDF (core), ne LDF (akyi) mu yɛ no panels a ne kɛse te sɛ nea ɛho hia (a ɛne ɔpon no frame nsusuwii hyia).

Sand wɔ layer biara ani na yi burrs na hwɛ hu sɛ ɛyɛ tratraa (ɛho hia ma tight interlayer bonding).

Nneɛma a Wɔde Kata Ntama So:

Fa ade a ɛyɛ pɛ a ɛyɛ nwini-a ɛko tia ade a wɔde kata so no gu bonding surfaces a ɛwɔ core (MDF) ne back (LDF) layers no so. Wɔhwɛ dodow a wɔde nkata so no so na wɔakwati sɛ ɛbɛtwetwe dodo (a ebetumi ama ayɛ warping) anaasɛ ɛnyɛ nea ɛdɔɔso (a ɛde delamination ba).

Layer Lamination: Ɔde ne nsa kyerɛɛ ne so.

Stack layers no nnidiso nnidiso: Surface HDF → Core MDF → Back LDF (anaasɛ reverse ma abien-afã a wɔde di dwuma).

Mia nnua a wɔaboaboa ano no wɔ afiri a wɔde tintim nneɛma a ɛyɛ hyew mu: fa nhyɛso (10–15 MPa) ne ɔhyew (120–150℃) gu so simma 5–10 na ama ade a wɔde nkata so no ayɛ aduru na abɔ ntoatoaso no mu ayɛ no kyerɛwpon a ɛyɛ den biako.

Post-Nneɛma a Wɔde Di Dwuma:

Twitwa laminated board no ma ɛnyɛ ɔpon no nnua kɛse pɛpɛɛpɛ (sɛ nhwɛso no, 80mm trɛw ma standard interior door frames).

Fa CNC mfiri fa kwan anaa mill grooves (ma apon ano nsɔano) ne ntokuru (ma hinges/locks) denam CNC mfiri so ma ɛyɛ pɛpɛɛpɛ.

Anhwea anoano ne ne soro bio de siesie wo ho ma afɛfɛde a wɔde wie (sɛ nhwɛso no, mfoniniyɛ, veneering).

Nhwehwɛmu a Wɔyɛe wɔ Nneɛma a Ɛyɛ Paara Mu:

Hwɛ sɛ delamination (peeling between layers), warping (maximum deviation Ennu anaasɛ ɛne 1mm/m yɛ pɛ), ne ɔfasuo so sintɔ (scratches, bubbles). Ntaaboo a wɔfata nkutoo na wɔkɔ so yɛ ɔpon no nnua a wɔboaboa ano.
