2. Nhyehyɛe a wɔyɛ na ɛma onwini .

Eyi ne ade titiriw a ɛbɛma wɔahu sɛnea board no yɛ petee na ne soro yɛ fɛ.

·Mmiɛnsa roll kalenda:

·Function: Eyi ne ade titiriw a ɛyɛ mprɛte a ɛyɛ den no. Ntɛmntɛm a efi nkuku no mu ba no hyɛn ɔkwan a ɛda nhama abiɛsa no ntam no mu ntɛm ara, wɔbobɔw, ɛyɛ nwini, na ɛyɛ sɛnea ɛte, na enya ɔfasu a ɛhyerɛn.

·Nhyehyɛe: mpɛn pii no ɛyɛ rollers abiɛsa: atifi, mfinimfini, ne ase. Roller no mu yɛ spiral flow channel abien, a wɔde ngo a ɛyɛ hyew daa ahyɛ mu ma ma ɛyɛ hyew pɛpɛɛpɛ.

·Roller nhyehyɛe: Ɛwɔ hɔ a ɛteɛ, ɛkɔ soro, ne 45℃angled ahorow. 45℃oblique angle no na ɛtaa ba efisɛ ɛma ɛyɛ mmerɛw sɛ abɔde mu ntrɛwmu a ɛwɔ melt no mu no yɛ mmerɛw na ɛtew emu adwennwen so.

·Medium height compensation: Esiane sɛ roller no asɛe kakra wɔ nhyɛso ase nti, wɔtaa yam roller a ɛwɔ ase no ma ɛyɛ "medium height" (convexity) pɔtee bi de tua deformation no so ka na ɛhwɛ ma krataa a wɔabobɔw no mu yɛ pɛ.

·Roll gap adjustment: Roll gap biara betumi ayɛ nea ɛde ne ho wɔ anyinam ahoɔden anaa hydraulically mu ma ɛne krataa no mu duru ahorow hyia.

·Nneɛma a wɔde fa nneɛma so a ɛyɛ nwini:

·Function: kɔ akyiri ma cool a wɔadi kan ayɛ no mmobɔwee board abiɛsa kosi dan mu hyew.

·Nhyehyɛe: a ɛyɛ akuw pii (mpɛn pii no, du du pii) a ɛyɛ passive anaasɛ actively driven rollers. Nhyɛso a ɛboa a ɛboa ma board no ntumi nkyinkyin.

·Ɔkwan a wɔfa so yɛ nwini: abɔde mu onwini anaasɛ mframa a ɛma onwini ka ho.

3. traction ne cutting nhyehyɛe .

·Traction afiri: .

·Function: Fa traction a ɛyɛ den ma de kyerɛ board no kwan yiye fi rollers abiɛsa no mu ne cooling frame no mu. Mpɛn pii no, ɛyɛ rɔba anaa silicone rollers abien anaa nea ɛboro saa, na wobetumi de mframa abɔ soro roller no akɔ fam.

·Automatic cutting/stacking afiri:

·Tytracking type cutting saw: bere a wɔretwitwa no, saw pon no di dwuma bere koro mu di board no kankyee akyi, ɛsan kɔ ne mfitiase gyinabea bere a wɔatwa awie no, na etumi twa ne tenten a ɛyɛ pintinn a wɔatwa no yiye.

·Stacker crane: automatically nya boards a wɔatwa na ɛboaboa ano fɛfɛɛfɛ. Automated stacking ho hia kɛse ma board ahorow a emu yɛ duru.

4. Nhyehyɛe a ɛboa .

·Adidi nhyehyɛe: vacuum suction afiri, a ɛde nneɛma a wɔde yɛ nneɛma fi silo no mu kɔ extruder hopper no mu.

·Mixing Machine: Sɛ ɛho hia sɛ wɔde kɔla masterbatch anaa nneɛma foforo ka ho a, ɛsɛ sɛ wodi kan fra afiri a wɔde fra nneɛma pɛpɛɛpɛ.

·Hydraulic System: Ɛma tumi ma screen changers, mold adjustments, ne nea ɛkeka ho.

·Ɔhyew sohwɛ nhyehyɛe: ɛma ɔhyew ne onwini a ɛyɛ pɛpɛɛpɛ ma extruders, nkuku, ne rollers abiɛsa (oil temperature afiri, nsu hyew afiri).

·Electrical control system: centralized control system a egyina PLC ne touch screen so, a ɛka motor drives nyinaa bom, ɔhyew sohwɛ, parameter nhyehyɛe, ne mfomso a wohu.

·PP (polypropylene): .

·Crystalline nneɛma no wɔ onwini a ɛtwetwe no kɛse.

·Process key: Mmiɛnsa roll temperature control ho hia paa. Ɛnsɛ sɛ roller no hyew no ba fam dodo, anyɛ saa a board no bɛyɛ brittle esiane crystallization a ɛrekɔ so ntɛmntɛm nti, na emu adwennwen no bɛyɛ kɛse, na ɛbɛma ayɛ mmerɛw sɛ ɛbɛkyinkyin wɔ akyiri yi fã no mu. Mpɛn pii no, ɛho hia sɛ wɔde roller hyew a ɛkɔ soro (te sɛ 80-100℃C) na ama onwini a ɛyɛ mmerɛw no ayɛ mmerɛw.

·Surface treatment: PP board no ani nyɛ non{0}}polar. Sɛ ɛho hia sɛ wotintim anaasɛ ɛkyekyere a, wobetumi de corona aduru a wɔde sa yare no ahyɛ baabi a wɔyɛ no akyi.

·PE (Polyethylene): .

·Ne titiriw HDPE, a crystallinity a ɛkorɔn ne melt viscosity a ɛkorɔn.

·Process key: Ɛte sɛ PP no, ɛsɛ sɛ wɔde adwene si onwini nhyehyɛe no so na amma wankyinkyin. Ɔhyew a wɔde yɛ adwuma no trɛw.

·ABS (Acrylonitrile Butadiene Styrene Copolymer):

·Amorphous nneɛma no yɛ nea ɛyɛ mmerɛw kɛse wɔ ɔhyew ho, ɛyɛ mmerɛw sɛ ɛbɛsɛe na ayɛ kɔkɔɔ.

·Ɔkwan a wɔfa so yɛ adwuma no:

·Processing temperature: Di ɔhyew a ɛwɔ ɔfã biara mu no so pɛpɛɛpɛ na amma ɔhyew antra mu. Ɛsɛ sɛ screw design kwati shear heat a ɛboro so.

·Cooling: sɛ amorphous plastic no, ABS wɔ cooling shrinkage rate a ɛba fam sen PP/PE, nanso ɛhwehwɛ sɛ rollers abiɛsa no yɛ mmerɛw yiye na ama wɔanya gloss surface a ɛkorɔn.

·Drying: Ɛsɛ sɛ wodi kan ma ABS raw materials no we yiye! Mpɛn pii no, ɛsɛ sɛ wɔma ɛyow wɔ 80-85℃C mu nnɔnhwerew 3-4 anaa nea ɛboro saa, anyɛ saa a kyerɛwpon no bɛma ahurututu anaa nsu agyiraehyɛde aba.

Nneɛma a wɔde yɛ adwuma → Drying (ABS hia) → Extruder plasticization → Filter ne screen changer → gear pump stabilization (optional) → Mold forming → abiɛsa roll calendering ne shaping → onwini ne conveying → awie → stacking → stacking → stacking

Sɛ ɛho hia sɛ wususuw ho sɛ wobɛtɔ nnwinnade a ɛte saa anaasɛ woasusuw ho a, ɛsɛ sɛ wohwɛ yiye:

1. Nneɛma a wɔyɛ ne board no ho nsɛm: Kyerɛkyerɛ mu pefee sɛ ne tɛtrɛtɛ a ɛsen biara/anyɛ yiye koraa no, ne kɛse, ne ne botae a wɔde yɛ adwuma (kg/h) a ɛwɔ board ahorow a wɔhwehwɛ no mu.

.

3. Control Level: Dodow a automation dodow kɔ soro no, dodow no ara na ɛyɛ mmerɛw sɛ wɔbɛyɛ adwuma no, na dodow no ara na ade no yɛ nea ɛyɛ den (te sɛ automatic thickness measurement feedback system).

4. Ɔyɛfoɔ Osuahu: Fa wɔn a wɔde nneɛma ma a wɔn PP/PE/ABS mprɛte a ɛyɛ den di nkonim no di kan.
