Indlela ye-PVC ye-Calendering yaphansi iyinqubo yokukhiqiza ephumelelayo neqhubekayo, efaneleka ngokukhethekile ukukhiqizwa kwamashidi esakhiwo alinganayo futhi avumeleke (njenge-commercial homogeneous permeable flooring). Umongo wayo uwukwenza ipulasitiki ye-PVC encibilikisiwe ibe ungqimba oluncane olufana noluncane ngokusebenzisa i-multi-roll calender, bese uyipholisa ukuze ibumbe. Okulandelayo yizinyathelo ezithile kanye namaphoyinti okulawula ezobuchwepheshe abalulekile:
I. Inqubo Yekhalenda
I-Raw Material Pretreatment > Ukuxuba okushisayo okusheshisa kakhulu, ukuhlanganisa okupholisa nokubandayo, ukuxuba kwangaphakathi nokwenza ipulasitiki, ukuxuba okuvulekile kanye nokuphakela
I-4-roll calendering, i-embossing/laminating, ukupholisa nokubumba, ukunquma nokusonta
II. Isinyathelo ngesinyathelo Amaphuzu Abalulekile kanye Nemingcele Yezobuchwepheshe
1. I-Raw Material Pretreatment kanye Nokuxuba
Ukubunjwa Kwefomula (Isibonelo): - I-PVC resin (uhlobo lwe-S-70) izingxenye eziyi-100, - I-Plasticizer (DINP/i-ester enobungani bemvelo) izingxenye ezingama-40-60, - I-Calcium carbonate filler (1250 mesh) izingxenye ezingama-50-80, - I-Heat stabilizer (i-calcium zinc composite, i-calcium zinc composite, izingxenye ze-Lubricant 5-1) izingxenye ze-Lubricant 3-5) - I-pigment (i-titanium dioxide/impushana yombala wezinto ezingaphili) izingxenye ezi-2-10
Inqubo Yokuxuba*:
Ukuxuba okushisayo: I-mixer yesivinini esiphezulu (≥1000 rpm), ukushisa ku-120 ° C (imizuzu engu-10-15) ukuvumela i-PVC ukuba ibambe i-plasticizer; Ukuxuba Okubandayo: Kuphole ngokushesha kuze kube ngaphansi kuka-40°C (ukuvimbela izigaxa), isikhathi sokuxuba okubandayo ≤ amaminithi angu-8.
2. Ukwenza ipulasitiki kanye nokudla
- I-Mixer Yangaphakathi: Izinga lokushisa 160-170 ° C, Ingcindezi 12-15 MPa, Isikhathi 4-6 imizuzu → Ukwakha inqwaba yerabha elinganayo;
I-Mixer evuliwe: Izinga lokushisa le-Twin-roll 165±5°C, i-Roller Gap 3-5 mm → Sika ube yimicu ukuze uphakele ikhalenda.
3. Ikhalenda ye-Four-roller (Inqubo Eyinhloko)
- Amasu Abalulekile:
- I-Roller Speed Ratio: 1#:2#:3#:4# = 1:1.1:1.05:1.0 (ukuvimbela ukuqoqwa kwezinto);
- Isinxephezelo Sobude Obuphakathi: I-Roller 2 yakhelwe ngomqhele ongu-0.02-0.05mm ukuze isuse ukuguquguquka kokugoba okushisayo. 4. Ukwelashwa Okungaphezulu Nokucwecwa
I-Embossing: I-embossing roller (i-silicone / insimbi) izinga lokushisa elingu-140-150 ° C, ingcindezi engu-0.5-1.0 MPa, isivinini esihambisana nomugqa we-calendering;
I-Substrate Lamination (Ongakukhetha): Indwangu ye-fiber yengilazi/indwangu engalukiwe, eshiswe ngaphambilini (100°C), ifakwe i-PVC incibilika ku-roller #3 ukuze kuthuthukiswe ukuzinza kwe-dimensional.
5. Ukupholisa nokuBunjwa
Izinga lokushisa lerola lokupholisa lezigaba ezintathu:
Ukulawula Ukuqina: I-Winding tension 10-15 N/mm² (ukuvikela ukushwabana okubandayo nokuguqulwa).
6. Ukunquma kanye Nokusonga
- Isilinganiso Sokuqina Kwe-Laser Online: Impendulo yesikhathi sangempela ilungisa igebe le-roller (ukunemba ± 0.01mm);
- Ukunquma Okuzenzakalelayo: Ububanzi beScrap ≤ 20mm, bugaywe kabusha futhi bufakwe i-pelletized ukuze buphinde busetshenziswe;
- Ukusonteka: Ukusonteka kwesikhungo esicindezelayo njalo, ububanzi be-roll Φ800-1200mm. III. Ubunzima Benqubo Nezixazululo
1. Ubukhulu obungalingani. Imbangela: Ukushintshashintsha kwezinga lokushisa kwerola > ±2°C. Isixazululo: I-Closed-Loop Thermal Temperature Control + Ukupholisa Kwerola Evaliwe.
2. I-Surface Gas. Imbangela: Ukuxuba Ukukhipha Igazi Okungenele. Isixazululo: Vacuum i-Internal Mixer (-0.08 MPa).
3. Imifantu yoMphetho. Imbangela: Ukupholisa Okudlulele/Ukucindezeleka Okudlulele. Isixazululo: Yehlisa I-Front-End Cooling Intensity bese Wengeza Indawo Yokupholisa Enensayo.
4. Iphethini Die. Imbangela: Ingcindezi Yerola Ye-Embossing Enganele. Isixazululo: Nyusa i-Hydraulic Pressure ibe ngu-1.2 MPa futhi Hlanza i-Roller Surface.
IV. Izinqubo Ezithuthukisiwe Zemvelo Nezokusebenza
1. Ukushintshwa Kwesinzinzisi Esingenamthofu:
- I-Calcium-Zinc Composite Stabilizer + β-Diketone Synergist → Iphumelele Ukuhlolwa Kokufuduka kwe-EN 14372;
2. Ipulasitiki Enobungani Nemvelo:
- I-DINP (i-Diisononyl Phthalate) → I-Cyclohexane 1,2-Dicarboxylate (Ecoflex®) Yehlisa I-Ecotoxicity.
3. Ukugaywa kabusha kukadoti:
- Izinsalela ezichotshozwayo → Ukuhlanganisa nokokusebenza okusha ngesilinganiso esingu-≤30% → Kusetshenziswa ekukhiqizeni ungqimba oluyisisekelo.
V. Ikhalenda vs. I-Extrusion (Ukuqhathanisa Uhlelo Lokusebenza)
Ukwakheka Komkhiqizo: Iphansi elinezimbobo ezilinganayo/Inhlanganisela yezingqimba eziningi, Ukukhishwa okuhlangene kwezingqimba eziningi (ungqimba olumelana nokugqokwa + ungqimba lwegwebu)
Ibanga Lokuqina: 1.5-4.0mm (Ukunemba ±0.1mm), 3.0-8.0mm (Ukunemba ±0.3mm)
I-Surface Finish: I-gloss ephezulu/I-Precision embossing (ukulingiswa kwezinhlamvu zokhuni), ukuthungwa kwe-Matte/Rough
Izicelo Ezijwayelekile: I-Homogeneous perforated flooring ezibhedlela nasemalabhorethri, i-SPC interlocking flooring yezindlu
Isifinyezo: Inani eliwumongo lendlela yokuhlelwa kwekhalenda lisemandleni "ukunemba okuphezulu" kanye "nokuvumelana okuphezulu"
- Izinzuzo Zenqubo:
- Ukulawula izinga lokushisa kwerola elinembile → I-coefficient yokwehluka kokuqina <1.5%;
- In-line embossing kanye lamination → Zuza itshe/metal visual effects;
- Imikhiqizo Esebenzayo:
Iphansi le-PVC elinembobo elinganayo elinezidingo zokuzinza ezinobukhulu obuphakeme (njengochungechunge lwe-Tarkett Omnisports);
- Thuthukisa Izinketho:
- Ukulawula Okukhaliphile: Ukulungiswa kwegebe le-roller elinamandla le-AI (impendulo yokuqina kwesikhathi sangempela);
- Ukubuyisela Amandla: Ukushisa kwemfucuza yamanzi okupholisa kusetshenziswa ekushiseni kwempahla eluhlaza (konga amandla angama-30%).
> Qaphela: Ekukhiqizeni kwangempela, izinga lokushisa le-calendering kanye nesivinini se-roller kufanele kulungiswe ngokuvumelana nefomula ye-fluidity (inkomba ye-mellt MFI = 3-8g / 10min) ukugwema ukuwohloka (inkomba ephuzi ΔYI <2).
