PVC pon so panel extrusion afiri line .

Nnwinnade titiriw a wɔde yɛ PVC WPC Hollow Door panels.

Saa ɔpon ano aduru yi yɛ ade a agye din yiye a wɔde yɛ apon a ɛwɔ dan mu ne apon a wɔde fa nnipa mu wɔ mprempren gua so, a nea ɛda nsow ne:

·Substrate: PVC (polyvinyl chloride) ne WPC (nnua plastic a wɔabom ayɛ), a ɛka bom yɛ plastic a ɛma nsu ntumi nkɔ mu ne nnua a wɔde yɛ powder no a wɔde afra.

·Nhyehyɛe: Hollow multi chamber structure, a ɛma ahoɔden bere a ɛyɛ hare na ɛma nnyigyei pa insulation ne thermal insulation effects.

·Surface: Mpɛn pii no wɔde PVC film kata so, ɛwɔ nneɛma a ɛyɛ fɛ a wɔde siesie nneɛma te sɛ nnua a wɔde ayɛ ne kɔla.

Sɛ wɔyɛ apon a ɛte saa a, ɛhwehwɛ sɛ wɔyɛ nhama a edi mũ, sen sɛ wɔde afiri biako bɛyɛ. Wɔfrɛ nnwinnade no nyinaa "PVC foam board/hollow door panel production line".

A standard PVC WPC hollow door panel production line titiriw ne afã horow a edidi so yi:

1. Nneɛma a wɔde frafra nneɛma mu .

Eyi ne adeyɛ no fã a edi kan, a ɛho hia kɛse.

·High speed hot mix machine: PVC resin, nnua powder, calcium powder, stabilizer, foaming agent, modifier ne nneɛma afoforo a wɔde yɛ raw no ka ho sɛnea formula ratio no te, wɔde afrafra ne plasticized wɔ high-speed rotation ne frictional heat generation ase, sɛnea ɛbɛyɛ a nneɛma ahorow a wɔde ka ho no betumi akɔ mu koraa akɔhyɛ resin no mu.

·Cold mixer: Nya nneɛma a ɛkorɔn-temperature nneɛma fi ɔhyew mixer, ntɛm ma wɔn ho dwo wɔn ma ɛyɛ hyew pɔtee (mpɛn pii no 40-50℃) denam nsu a ɛma onwini so, siw agglomeration ne premature plasticization ano, na ɛma ɛyɛ mmerɛw sɛ wɔde bɛkɔ akyiri na wɔakora so.

·Adwumayɛ: Nneɛma a wɔde yɛ no pɛpɛɛpɛ ne sɛnea ɛyɛ den no ne fapem a wɔde hwɛ hu sɛ ade a etwa to no yɛ papa.

2. Extrusion nhyehyɛe .

Nneɛma a wɔyɛ no mu ade titiriw ne sɛ wobewie nsakrae a efi nneɛma a wɔde yɛ nneɛma mu kɔ profile ahorow mu no.

·Conical twin-Screw extruder: Eyi ne host a wɔtaa de di dwuma sen biara. Nhama abien a ɛka bom no dannan ne ho wɔ toa no mu, de kɔ, mia so, nwene, ɛma ɛyɛ plastic, na ɛma powder a wɔde afra no yɛ pɛ.

·Advantages: mixing effect pa, low shear heat, a ɛfata ma processing heat sensitive PVC nneɛma, ahoɔden a ɛba fam koraa a wɔde di dwuma.

·Mold (ano nsusuwso): Eyi ne mfiridwuma mu ade titiriw, a ɛkyerɛ mmeamudua-afã no nsusuwii ne ne nhyehyɛe. Door panel mold a ɛyɛ tokuru no yɛ nea ɛyɛ den yiye, na ɛwɔ akwan pii ne core molds mu ma ɛyɛ multi chamber hollow structure a etwa to. Nkuku no nhyehyɛe ne sɛnea wɔyɛ no pɛpɛɛpɛ no na ɛkyerɛ sɛnea ade no te tẽẽ.

3. Standardized Cooling System .

Fa-temperature molten profile a ɛkorɔn no yɛ den fi nkuku no mu kɔ ne nsusuwii a etwa to no mu.

·Vacuum shaping table: a ɛyɛ vacuum a wɔde yɛ nsuo a ɛwɔ nsuo a wɔde yɛ nsuo a ɛwɔ nsuo mu no dodoɔ (mpɛn pii no 3-4). Sɛ profile no fa nsu a ɛwɔ mu no mu a, wɔde vacuum adsorption bata nsusuwii nsusuwso no ho denneennen, na ɛma ɛyɛ nwini ntɛmntɛm na ɛyɛ den denam nsu a ɛma onwini a ɛredi akɔneaba so.

·Eyi yɛ anammɔn titiriw a ɛbɛma woanya nsusuwii a ɛyɛ pɛpɛɛpɛ ne soro a ɛyɛ mmerɛw.

4. Traction afiri .

Fa nhyɛso a ɛyɛ den na ɛkɔ so ma de twe profile no fi nkuku no mu wɔ ahoɔhare a ɛyɛ pɛ mu, hwɛ hu sɛ nneɛma a wɔyɛ no kɔ so na ɛma nsɛm no nsusuwii gyina pintinn.

·Crawler trakta ne nea ɛtaa ba, a ɛde nsɛm abien a ɛwɔ soro ne ase di dwuma de kyere nsɛm ma ɛtwetwe.

5. Afiri a wɔde twa ade .

Twe profile ahorow no ankasa sɛnea wɔahyɛ no tenten (mpɛn pii no, ɔpon no kɛse a ɛyɛ gyinapɛn, te sɛ mita 2.1, mita 2.4).

·Planetary saw/circular saw: saw blade no ne profile no hyia bere koro mu ma wotwa, na nea wotwa no yɛ petee na ɛyɛ mmerɛw.

6. Flip Rack/Stacker Krane .

Ɔgye apon a wɔatwa no ara kwa na ɛboaboa ano fɛfɛɛfɛ ma ɛyɛ mmerɛw sɛ wobedi ho dwuma na wɔde ahyɛ mu.

Nneɛma a wɔde gyina so a wopɛ (a ɛma nneɛma a ɛwɔ soro no yɛ kɛse) .

Wɔ apon a wɔde kata so a ɛhwehwɛ sɛ wɔde nneɛma gu so no, ɛsɛ sɛ nhama a wɔde yɛ nneɛma no nso de nnwinnade a edidi so yi ka ho:

7. Online laminating afiri .

Afei extrusion of the profile ne ansa nahyɛn shaping stage no, PVC decorative film no abɔ profile no ani denam ɔhyew ne nhyɛso kɛse so.

·Advantages: Sini no wɔ adhesion a emu yɛ den wɔ substrate no ho, enhia sɛ wɔde petepete akyi, nsusuwso a ɛyɛ nokware, na wobetumi awie no prɛko pɛ.

Raw Material Formula → High-Speed ​​Hot Mixing → Cooling → Silo Storage → Conical twin-Screw extruder extrusion → Molding through mold → (optional: online film coating) → vacuum on cooling shaping → track traction
