Uburyo bwa PVC bwo kubara ni uburyo bwiza kandi bukomeza bwo gukora, bukwiranye cyane cyane no gukora impapuro zubatswe kandi zemewe (nk'ubucuruzi bwa homogeneous permeable etage). Intangiriro yacyo ni uguhindura PVC yashongeshejwe muburyo bumwe bworoshye unyuze kuri kalendari myinshi, hanyuma ukayikonjesha kugirango ube. Ibikurikira nintambwe zihariye ningingo zingenzi zo kugenzura tekinike:
I. Uburyo bwo gutanga amakuru
Kwirinda ibikoresho bito> Kwihuta kuvanga ubushyuhe, gukonjesha no kuvanga imbeho, kuvanga imbere no gukora plastike, kuvanga no kugaburira
Kuzenguruka inshuro enye, gushushanya / kumurika, gukonjesha no gushushanya, gutema no kuzunguruka
II. Intambwe ku yindi Gukora Ingingo z'ingenzi n'ibipimo bya tekiniki
1. Gutegura ibikoresho bito no kuvanga
Ibigize formulaire (Urugero): - PVC resin (ubwoko bwa S-70) ibice 100, - Plastiseri (DINP / ester yangiza ibidukikije) ibice 40-60, - Kalisiyumu ya karubone yuzuza (mesh 1250) ibice 50-80, - Ubushyuhe bwa stabilisateur (calcium zinc composite) ibice 3-5, - Lubricant (acide stearic) 0.5-1 igice, - Pigment
Uburyo bwo kuvanga *:
Kuvanga bishyushye: Kuvanga umuvuduko mwinshi (≥1000 rpm), ubushyuhe bugera kuri 120 ° C (iminota 10-15) kugirango PVC yinjize plastike; Kuvanga ubukonje: Byihuse bikonje munsi ya 40 ° C (kugirango wirinde ibibyimba), igihe cyo kuvanga imbeho ≤ iminota 8.
2. Gutera no kugaburira
- Imvange y'imbere: Ubushyuhe 160-170 ° C, Umuvuduko 12-15 MPa, Igihe iminota 4-6 → Gukora misa ya reberi imwe;
Gufungura kuvangavanga: Ubushyuhe bwa Twin-roll 165 ± 5 ° C, Roller Gap 3-5 mm → Kata mumirongo kugirango uhore ugaburira kalendari.
3. Calendering ya roller enye
- Ubuhanga bw'ingenzi:
- Ikigereranyo cyihuta cya Roller: 1 #: 2 #: 3 #: 4 # = 1: 1.1: 1.05: 1.0 (kugirango wirinde gukusanya ibintu);
- Indishyi zo hagati-Hejuru: Roller 2 yateguwe hamwe na 0.02-0.05mm ikamba kugirango igabanye ihindagurika ryumuriro. 4. Kuvura Ubuso no Kumurika
Gushushanya: Gushushanya roller (silicone / ibyuma) ubushyuhe 140-150 ° C, umuvuduko 0.5-1.0 MPa, umuvuduko uhuye numurongo wa kalendari;
Substrate Lamination (Bihitamo): Ikirahuri cya fibre mat / imyenda idoda, yashyutswe (100 ° C), yomekwa hamwe na PVC yashonga kuri roller # 3 kugirango iteze imbere urwego.
5. Gukonjesha no gushiraho
Ibyiciro bitatu byo gukonjesha ubushyuhe bwa roller:
Kugenzura Umujinya: Guhagarika impagarara 10-15 N / mm² (kugirango wirinde kugabanuka gukonje no guhinduka).
6. Gutema no Kuzunguruka
- Gupima Ubunini bwa Laser Kumurongo: Ibitekerezo-nyabyo bihindura icyuho cya roller (ubunyangamugayo ± 0.01mm);
- Gutunganya byikora: Ubugari bwakuweho ≤ 20mm, byongeye gukoreshwa no gutondekwa kugirango bikoreshwe;
- Guhinduranya: Guhorana impagarara zihoraho, kuzunguruka diameter Φ800-1200mm. III. Inzira Ingorane n'ibisubizo
1. Ubunini butaringaniye. Impamvu: Ihindagurika ry'ubushyuhe bwa Roller> ± 2 ° C. Igisubizo: Gufunga-Kuzenguruka Amavuta yubushyuhe bwo kugenzura Ubushyuhe + Gufunga-Gukonjesha Roller Cooling.
Gazi yo hejuru. Impamvu: Kuvangavanga bidahagije. Igisubizo: Vuga Vuga Imbere (-0.08 MPa).
3. Ibice byacitse. Impamvu: Ubukonje bukabije / Umujinya ukabije. Igisubizo: Mugabanye ubukonje bwimbere-Impera hanyuma wongereho akonje gahoro.
4. Icyitegererezo Gupfa. Impamvu: Umuvuduko udasanzwe wo gushushanya. Igisubizo: Ongera Umuvuduko wa Hydraulic kuri 1.2 MPa hanyuma Sukura Ubuso bwa Roller.
IV. Ibidukikije byangiza ibidukikije nibikorwa byazamuye inzira
1. Gusimbuza Ubusa-Gusimbuza Stabilisateur:
- Kalisiyumu-Zinc Igizwe na Stabilisateur + β-Diketone Synergist → Yatsinze EN 14372 Ikizamini cyo Kwimuka;
2. Ibidukikije byangiza ibidukikije:
- DINP (Diisononyl Phthalate) → Cyclohexane 1,2-Dicarboxylate (Ecoflex®) Igabanya Ecotoxicity.
3. Gutunganya imyanda:
- Kumenagura ibisigazwa → Kuvanga nibikoresho bishya ku kigereranyo cya ≤30% → Byakoreshejwe mubikorwa fatizo.
V. Calendering na Extrusion (Kugereranya gusaba)
Imiterere y'ibicuruzwa: Homogeneous perforated etage / Multi-layer compte, Multi-layer co-extrusion (layer-resistance layer + foam layer)
Urwego rwubunini: 1.5-4.0mm (Ukuri ± 0.1mm), 3.0-8.0mm (Ukuri ± 0.3mm)
Kurangiza Ubuso: Ububengerane buhebuje / Gushushanya neza (kwigana ingano y'ibiti), Matte / Imiterere idakabije
Ubusanzwe Porogaramu: Igorofa ya homogeneous igorofa mubitaro na laboratoire, SPC ihuza amagorofa kumazu
Incamake: Agaciro shingiro k'uburyo bwa kalendari iri muri "precision precision" na "guhuza cyane"
- Ibyiza byo gutunganya:
- Kugenzura ubushyuhe bwa roller neza → Coefficient ihindagurika yubushyuhe <1.5%;
- Kumurongo wo gushushanya no kumurika → Kugera kumabuye / ibyuma byerekana amashusho;
- Ibicuruzwa bikoreshwa:
Homogeneous perforated PVC hasi hamwe nibisabwa murwego rwo hejuru (nka Tarkett Omnisports ikurikirana);
- Kuzamura Amahitamo:
- Igenzura ryubwenge: AI ikoreshwa na dinamike ya roller itandukanya (ibitekerezo byukuri-byukuri);
- Kugarura ingufu: Ubushyuhe bwo gukonjesha amazi bukoreshwa mugushushanya ibikoresho bibisi (kuzigama ingufu 30%).
