The PVC mokatong calendering mokhoa ke tshebetso e sebetsang hantle le e tsoelang pele tlhahiso, e leng ka ho khetheha e loketseng bakeng sa tlhahiso ea homogeneous le permeable sebopeho maqephe (joaloka khoebo homogeneous permeable flooring). Moko oa eona ke ho etsa polasetiki ea PVC e qhibilihisitsoeng hore e be lesela le lesesaane le lekanang ka har'a calender ea li-roll tse ngata, ebe o e pholisa hore e bōpehe. Tse latelang ke mehato e ikhethileng le lintlha tsa bohlokoa tsa taolo ea tekheniki:
I. Mokhoa oa Khalendara
Raw Material Pretreatment > Ho kopanya ho chesang ka lebelo le phahameng, ho kopanya ho pholisa le ho bata, ho kopanya ka hare le polasetiki, ho kopanya ho bulehileng le ho fepa.
Kalendara ya meqolo e mene, embossing/laminating, phodiso le sebopeho, ho poma le ho tswedisa
II. Lintlha tsa Bohlokoa tsa Ts'ebetso ea Mohato ka Bohato le Liparamente tsa Tekheniki
1. Raw Material Pretreatment le Ho Kopanya
Foromo Sebopeho (Mohlala): - PVC resin (S-70 mofuta) 100 likarolo, - Plasticizer (DINP / tikoloho botsoalle ester) 40-60 likarolo, - Calcium carbonate filler (1250 mesh) 50-80 likarolo, - Mocheso stabilizer (calcium zinc composite, 5-1 karolo ea lubricant) - 3-5 likarolo tsa acid-1) - Pigment (titanium dioxide / inorganic color powder) likarolo tse 2-10
Mokhoa oa ho Kopanya*:
Ho kopanya ho chesang: Motsoako oa lebelo le phahameng (≥1000 rpm), mocheso ho 120 ° C (metsotso e 10-15) ho lumella PVC hore e amohele polasetiki; Ho kopanya ho batang: Ho pholile ka potlako ho ea ka tlase ho 40 ° C (ho thibela maqeba), nako ea ho kopanya e batang ≤ 8 metsotso.
2. Plasticizing le Feeding
- Motsoako oa ka hare: Mocheso oa 160-170 ° C, Khatello ea 12-15 MPa, Nako ea 4-6 metsotso → Ho theha boima ba rabara e homogeneous;
Open Mixer: Mocheso oa twin-roll 165±5°C, Roller Gap 3-5 mm → Khaola likotoana bakeng sa phepelo e tsoelang pele ho khalendara.
3. Four-roller Calender (Core Process)
- Mekhoa ea Bohlokoa:
- Roller Speed Ratio: 1#:2#:3#:4# = 1:1.1:1.05:1.0 (ho thibela ho bokella lintho);
- Matšeliso a Bophahamo ba Bohareng: Roller 2 e entsoe ka moqhaka oa 0.02-0.05mm ho felisa deformation ea ho kobeha ha mocheso. 4. Kalafo ea Bokaholimo le Lamination
Embossing: Embossing roller (silicone / tšepe) mocheso 140-150 ° C, khatello ea 0.5-1.0 MPa, lebelo le lumellanang le mohala oa calendering;
Substrate Lamination (Boikhethelo): Lesela la fiber ea khalase / lesela le sa lohiloeng, le chesitsoeng pele (100 ° C), le entsoe ka laminated le PVC e qhibilihisitsoeng ho rolara #3 ho matlafatsa botsitso ba dimensional.
5. Ho pholisa le ho Shaping
Mehato e meraro ea mocheso oa rolara:
Taolo ea tsitsipano: Ho tsitsinyeha ha moea 10-15 N/mm² (ho thibela ho honyela ha serame le ho senyeha).
6. Ho fokotsa le ho Felisa
- Tekanyo ea Botenya ba Laser Online: Maikutlo a nako ea sebele a fetola lekhalo la roller (ho nepahala ± 0.01mm);
- Ho itšeha ka mokhoa o iketsang: Bophara ba sekhechana ≤ 20mm, bo ntlafalitsoe hape le pelletized hore bo sebelisoe hape;
- Ho tsubella: Ho tsoelipana ha setsi sa tsitsipano kamehla, bophara ba moqolo Φ800-1200mm. III. Mathata a Ts'ebetso le Litharollo
1. Botenya bo sa Lekaneng. Sesosa: Ho Fetoha ha Mocheso oa Roller > ±2°C. Tharollo: Taolo ea Mocheso oa Mocheso oa Oli e Koetsoeng + e Koetsoeng ka Roller Cooling.
2. Khase ea Bokaholimo. Sesosa: Ho sa Lekane Ho Kopanya Ho Hlakola Gassing. Tharollo: Vacuum the Internal Mixer (-0.08 MPa).
3. Mapheo a Edge. Sesosa: Pholiso e Feteletseng / Tsietsi e Feteletseng. Tharollo: Fokotsa Matla a ho Pholisa ka Pele 'me u Ekelle Sebaka sa ho Pholisa butle.
4. Mohlala Shoa. Sesosa: Khatello e sa lekaneng ea Embossing Roller. Tharollo: Eketsa Khatello ea Hydraulic ho 1.2 MPa le ho Hloekisa Bokaholimo ba Roller.
IV. Mekhoa e Ntlafalitsoeng ke Tikoloho le Ts'ebetso
1. Phetisetso e sa Lefelloe ea Ketapele:
- Calcium-Zinc Composite Stabilizer + β-Diketone Synergist → E Feta Teko ea Phallo ea EN 14372;
2. Plasticizer e Sebeletsang Tikoloho:
- DINP (Diisononyl Phthalate) → Cyclohexane 1,2-Dicarboxylate (Ecoflex®) E Fokotsa Ecotoxicity.
3. Tšebeliso ea Matlakala:
- Likhechana tse pshatlang → Ho kopanya le lisebelisoa tse ncha ka karo-karolelano ea ≤30% → E sebelisoa tlhahiso ea lera la motheo.
V. Calendar vs. Extrusion (Application Comparison)
Sebopeho sa Sehlahisoa: Mekato e nang le perforated e nang le mefuta e mengata / Mehato e mengata e mengata, Multi-layer co-extrusion (lesela le sa tsitsang + lera la foam)
Botenya Range: 1.5-4.0mm (Ho nepahala ± 0.1mm), 3.0-8.0mm (Ho nepahala ± 0.3mm)
Qetello ea Bokaholimo: Ho benya ho phahameng / ho khabisoa ka mokhoa o nepahetseng (ho etsisa lijo-thollo tsa lehong), Sebopeho sa matte/Rough
Lits'ebetso tse Tloaelehileng: Mokato o nang le liphahlo tse nang le lipeo tse nang le lipetlele le lilaboratori, SPC e hokahaneng ea fuluru bakeng sa matlo.
Kakaretso: Boleng ba mantlha ba mokhoa oa calendering bo ho "ho nepahala ho phahameng" le "ho lumellana ho phahameng"
- Melemo ea Ts'ebetso:
- Taolo e nepahetseng ea mocheso oa rolara → Botenya bo fapaneng ba coefficient <1.5%;
- Embossing le lamination ka har'a mohala → Finyella litlamorao tsa ponahalo ea majoe / tšepe;
- Lihlahisoa tse sebetsang:
Phallo ea PVC e nang le perforated e nang le litlhoko tse phahameng tsa botsitso (joalo ka letoto la Tarkett Omnisports);
- Likhetho tsa ntlafatso:
- Taolo ea Bohlale: Phetoho ea lekhalo le matla la AI-powered dynamic roller (maikutlo a botenya ba nako ea nnete);
- Pholiso ea Matla: Mocheso oa litšila oa metsi o pholileng o sebelisoa bakeng sa ho futhumatsa thepa e tala (ho boloka matla a 30%).
> Tlhokomeliso: Ka tlhahiso ea sebele, mocheso oa calendering le lebelo la rolara li lokela ho fetoloa ho ea ka mokhoa oa metsi a metsi (melt index MFI = 3-8g / 10min) ho qoba ho senyeha (yellowing index ΔYI <2).
