Ole auala ole fa'akalena o le fola o le PVC o se fa'agasologa lelei ma fa'aauau pea le gaosiga, lea e sili ona talafeagai mo le gaosiga o pepa fa'apipi'i tutusa ma fa'afefeteina (e pei o fola fa'atosina fa'apisinisi). O lona autu o le fa'apipi'iina lea o le PVC liusuavai i totonu o se fa'amea manifinifi toniga e ala i le kalena tele-roll, ona fa'amalieina lea e fa'atusa. O lo'o taua i lalo la'asaga fa'apitoa ma 'autū fa'atonu fa'apitoa:
I. Fa'asologa o Kalender
Fa'ameamea Mu'a'ai > Fa'afefiloi vevela maualuga, fa'afefiloi ma le malulu, fa'afefiloi totonu ma palasitika, fa'afefiloi matala ma fafaga.
Fa'atala fa'akalena, fa'aulu/laminating, fa'alili ma fa'apena, teuteu ma fa'avili
II. La'asaga ma lea la'asaga Fa'atino Manatu Autu ma Parata Fa'ainisinia
1. Fa'ata'ita'iina o Mea Matagofie ma Fa'afefiloi
Fuafua Faatatau (Fa'aa'oa'oga): - PVC resin (ituaiga S-70) 100 vaega, - Plasticizer (DINP/si'osi'omaga ester ester) 40-60 vaega, - Calcium carbonate filler (1250 mesh) 50-80 vaega, - Fa'amautu vevela (calcium zinc composite) 3-5 vaega, - Lubricant-0 vaega, - Lubricant-0. (titanium dioxide / paʻu lanu inorganic) 2-10 vaega
Fa'agasologa Fa'afefiloi*:
Faʻafefiloi vevela: Faʻafefiloi maualuga (≥1000 rpm), vevela i le 120 ° C (10-15 minute) e faʻatagaina ai le PVC e faʻafefe le plasticizer; Fa'afefiloi malulu: Fa'amalo vave i lalo ole 40°C (ia puipuia fa'aputu), taimi fa'afefiloi malulu ≤ 8 minute.
2. Fa'apalapala ma Fafaga
- Fa'afefiloi Fa'alotoifale: Vevela 160-170°C, O'omi 12-15 MPa, Taimi 4-6 minute → Fa'atupuina o se pa'u pa'u tutusa;
Tatala Mixer: Lua-roll vevela 165±5°C, Roller Gap 3-5 mm → Otioti i fasi pepa mo le fafagaina pea i le kalena.
3. Fa'ato'a fa'ato'aga (Fa'agasolo Autu)
- Tekinolosi Autu:
- Fa'atatau o le Saosaoa o le Roller: 1#:2#:3#:4# = 1:1.1:1.05:1.0 (e taofia ai le faaputuputuina o mea);
- Taui Mid-Height: Roller 2 ua mamanuina ma le pale 0.02-0.05mm e faʻafefe ai le faʻaogaina o le vevela. 4. Togafitiga i luga ma Lamination
Embossing: Embossing roller (silicone / u'amea) vevela 140-150 ° C, mamafa 0.5-1.0 MPa, saoasaoa e fetaui ma le laina kalena;
Lamination Lapisi (Filifili): fala alava tioata / ie e le o lalagaina, mua'i fa'avevela (100°C), e fa'apalapala i le fa'afefeteina o le PVC i le roller #3 e fa'aleleia atili ai le mautu.
5. Fa'alili ma Fa'apena
Tolu-tulaga fa'amalo vevela vevela:
Fa'atonuga Fa'aletonu: Fa'alili fa'amalo 10-15 N/mm² (ia puipuia ai le fa'aitiitiga malulu ma fa'aletonu).
6. Teuga ma Ta'amilo
- Su'ega Mafiafia o le Laser Online: Fa'amatalaga lata mai e fa'afetaui ai le va o le ta'avale (sa'o ± 0.01mm);
- Otometi Tipi: Ma'a lapisi ≤ 20mm, toe fa'aaogaina ma pelleti mo le toe fa'aoga;
- Fa'aviliina: Ta'amilomilo le ogatotonu fa'alavelave, ta'amilosaga Φ800-1200mm. III. Faiga Faigata ma Fofo
1. Mafiafia lē tutusa. Mafua'aga: Fesuia'iga o le vevela o le taila > ±2°C. Fofo: Tapuni-Loop Suau'u vevela Pulea + Close-Drilled Roller Cooling.
2. Kesi i luga. Mafuaaga: Le lava Faafefiloi Degassing. Fofo: Fa'amama le mea fa'afefiloi totonu (-0.08 MPa).
3. Ta'eta'e pito. Mafua'aga: Fa'amalie tele/Teletete tele. Fofo: Fa'aiti'itia le Malosi Fa'alili i luma ma Fa'aopoopo se Sone Fa'alili lemu.
4. Oti Mamanu. Mafua'aga: Le lava Omiga Fa'a Ta'avale. Fofo: Faʻateleina le Faʻasaʻo o le Hydraulic i le 1.2 MPa ma faʻamama le Roller Surface.
IV. Faiga Fa'alelei ma Fa'aleleia Fa'atinoga
1. Suiga Fa'amautu Sa'o Ta'ita'i:
- Calcium-Zinc Composite Stabilizer + β-Diketone Synergist → Pasia EN 14372 Su'ega Femalagaa'i;
2. Plasticizer Fa'aSiosiomaga:
- DINP (Diisononyl Phthalate) → Cyclohexane 1,2-Dicarboxylate (Ecoflex®) Faʻaitiitia le Ecotoxicity.
3. Toe fa'aaogaina otaota:
- Tu'i fa'ameamea → Fa'afefiloi ma mea fou i le fua faatatau o le ≤30% → Fa'aaogaina i le gaosiga o fa'avae.
V. Calendering vs. Extrusion (Fa'atusa Fa'atatau)
Fauga o Oloa: Fa'ato'aga fola fa'a'ava'ava'ava'ava'a/Vaega fa'a-vaega tu'ufa'atasi, Fa'apipi'i fa'atasi fa'atasi (fa'a'ofu fa'a'ofuofu + fa'afu foam)
Va'aiga Mafiafia: 1.5-4.0mm (Sa'o ± 0.1mm), 3.0-8.0mm (Sa'o ± 0.3mm)
Fa'ai'uga o le Lau'ele'ele: I'ila maualuga/Ma'i sa'o le fa'ata'ita'iina (fa'ata'ita'i fa'ato'aga fa'ato'aga), Mate/Ala'a'ai.
Talosaga masani: Fa'ato'aga fola fa'ato'aga i falema'i ma fale su'esu'e, SPC feso'ota'i fola mo fale
Aotelega: O le aoga autu o le faiga fa'akalena o lo'o taoto i le "maualuga maualuga" ma le "maualuga maualuga"
- Fa'amanuiaga Fa'agasologa:
- Fa'atonuga o le vevela o le ta'avale → Fa'atasi o fesuiaiga o mafiafia <1.5%;
- Fa'amauina ma lamination i le laina → Ausia fa'aaliga vaaia ma'a/mea;
- Oloa talafeagai:
Fa'ato'aga fola PVC fa'atasi ma mana'oga mautu maualuga (e pei o le Tarkett Omnisports series);
- Fa'aleleia Filifiliga:
- Pulea Atamai: AI-powered dynamic roller gap adjustment (taimi moni manatu mafiafia);
- Malosiaga Toe Fa'aleleia: Fa'amalo vai fa'amama vevela e fa'aoga mo mea mata'utia fa'amea muamua (sefe 30% malosi).
> Faʻaaliga: I le gaosiga moni, e tatau ona fetuunaʻi le vevela o le kalena ma le saoasaoa o le taʻavale e tusa ai ma le fua faʻatatau (faʻamaufaʻailoga MFI = 3-8g / 10min) e aloese ai mai le faʻaleagaina (faʻailoga samasama ΔYI <2).
