Ko te tikanga whakamaarama o te papa PVC he mahinga pai me te mahi tonu, he mea tino pai mo te hanga i nga pepa hanganga riterite me te permeable (pēnei i te papa permeable arumoni). Ko tana kaupapa matua ko te whakaraerae i te PVC whakarewa ki roto i te paparanga angiangi kakahu ma te maramataka pukapuka-maha, ka whakamatao kia hanga. Ko nga waahanga e whai ake nei me nga waahanga whakahaere hangarau matua:
I. Tukanga Maramataka
Raw Material Pretreatment > Te whakakotahitanga wera tere, te whakamatao me te whakaranu makariri, te whakaranu o roto me te kirihou, te whakaranu tuwhera me te whangai
E wha-roera te maramataka, te whakaraerae, te whakamatao me te hanga, te kuti me te awhiowhio
II. Mahinga-ma-taahiraa Nga Tohu Matua me nga Tawhā Hangarau
1. Raw Material Pretreatment and Mixing
Hanganga Tātai (Tauira): - PVC resin (momo S-70) 100 nga wahanga, - Kaipara (DINP/ester taiao) 40-60 nga wahanga, - Whakakii konupora konupora (1250 mesh) 50-80 nga wahanga, - Te whakapumau wera (konupora konutea hiato) 3-5 nga wahanga, - Pikiwawawawawawawa whakakī (1250 mesh) 50-80 wahanga, - Whakapumau wera (konupora konupora hiato) 3-5 wahi, - Pikariki-waikawawawa (0) Waahanga Pipirika (0) (titanium dioxide/parakore paura tae) 2-10 wahi
Tukanga Ranu*:
Te whakaranu wera: Te tere tere tere (≥1000 rpm), te wera ki te 120 ° C (10-15 meneti) ki te tuku i te PVC ki te whakauru i te plasticizer; Whakaranu Matao: Tere whakamatao ki raro iho i te 40°C (ki te aukati i nga kapia), te wa whakaranu makariri ≤ 8 meneti.
2. Whakapaipai me te whangai
- Whakaranu Roto: Te Pawera 160-170°C, Peehanga 12-15 MPa, Wā 4-6 meneti → Te hanga papatipu rapa riterite;
Whakaranu Tuwhera: Maama-rua te pāmahana 165±5°C, Roera Gap 3-5 mm → Tapahia ki nga takai mo te whangai tonu ki te maramataka.
3. Maramataka wha-roera (Tukanga Matua)
- Tikanga Matua:
- Tauwehenga Tere Roera: 1#:2#:3#:4# = 1:1.1:1.05:1.0 (hei aukati i te whakaemi rauemi);
- Utu Waenganui-Teitei: Kua hangaia te Roera 2 me te karauna 0.02-0.05mm hei whakakore i te rerekeetanga o te piko o te waiariki. 4. Te maimoatanga Mata me te Lamination
Te Whakapaipai: Te roera embossing (silicone/steel) te pāmahana 140-150°C, te pehanga 0.5-1.0 MPa, te tere e rite ana ki te raina maramataka;
Rarangi Papa (Kōwhiringa): Ko te whariki muka karaihe/te papanga kore-whatu, kua whakawerahia (100°C), kua whakakikoruatia ki te rewa PVC i te roera #3 hei whakarei ake i te pumau o te ahu.
5. Te Matao me te Hanga
E toru-waahi te pāmahana roera whakamahana:
Te Mana Mana: Awhiowhio 10-15 N/mm² (hei aukati i te whakaheke matao me te paheketanga).
6. Te Kuti me te Awhiowhio
- Te Ine Matotoru Ipurangi Taiaho: Ko nga urupare-waahi ka whakatika i te waahi roera (tika ± 0.01mm);
- Te Kuti Aunoa: Ko te whanui parakore ≤ 20mm, te hangarua me te pelleti hei whakamahi ano;
- Awhiowhio: Awhiowhio tonu i te pokapu mahanga, te diameter o te pukapuka Φ800-1200mm. III. Tukatuka Nga uaua me nga otinga
1. Te Matotoru Korewari. Meinga: Hurirere Te Mamahana Roera > ±2°C. Rongoā: Katia-Loop Thermal Oil Temperature Control + Close-Drilled Roller Cooling.
2. Hau Mata. Take: He iti rawa te Whakaranutanga Whakarewa. Rongoā: Momoho te Whakaranu Roto (-0.08 MPa).
3. Kapiti Tapa. Te take: Te Matao o te Toka/Te Manawanui. Rongoa: Whakaitihia te Kaha Matao o Mua-Whakamutunga me te taapiri i tetahi Rohe whakamatao Puturi.
4. Tauira Mate. Take: He iti rawa te pehanga o te roera embossing. Rongoā: Whakanuia te Peehanga Hydraulic ki te 1.2 MPa me te Whakapai i te Mata Roera.
IV. Nga Tikanga Whakapai Taiao me te Mahinga Whakapai
1. Whakakapinga Whakapumau Lead-Free:
- Calcium-Zinc Composite Stabilizer + β-Diketone Synergist → Passes EN 14372 Migration Test;
2. Whakapaipai Taiao:
- DINP (Diisononyl Phthalate) → Cyclohexane 1,2-Dicarboxylate (Ecoflex®) Ka whakaiti i te Ecotoxicity.
3. Hangarua Parapara:
- Te kuru i nga kongakonga → Te whakakotahi me nga mea hou i te ōwehenga o ≤30% → Ka whakamahia ki te hanga paparanga turanga.
V. Maramataka vs. Tangohanga (Whakataurite Taupānga)
Hanganga Hua: Papanga puwau riterite/papa-maha-papa-maha, Whakapiringa-tahi-papa-maha (papa-atete kakahu + apa pahuka)
Awhe Matotoru: 1.5-4.0mm (Te tika ± 0.1mm), 3.0-8.0mm (Te tika ± 0.3mm)
Te Whakaoti Mata: He kanapa teitei/Pono te whakahiato (whakaritea i te witi rakau), te kakano Matte/Taara
Nga tono angamaheni: Ko nga papaa kowhatu riterite i roto i nga hohipera me nga taiwhanga, SPC papaa hono mo nga kaainga
Whakarāpopototanga: Ko te uara matua o te tikanga maramataka kei roto i te "tikanga teitei" me te "tino rite"
- Painga Tukatuka:
- Te mana o te pāmahana roera tika → Te whakarea rerekētanga mātotoru <1.5%;
- Raina-a-raina embossing and lamination → Tutuki te kohatu/whakarewa whakakitenga;
- Hua e tika ana:
Ko nga papaa PVC kowaowao riterite me nga whakaritenga pumau teitei (penei i te raupapa Tarkett Omnisports);
- Kōwhiringa Whakapai ake:
- Mana Maramarama: Ko te whakatikatika aputa roera hihiko a AI (he urupare te matotoru o te waa tuuturu);
- Whakaora Pungao: Ka whakamahia te wera para wai whakamahana mo te whakamahana i mua i nga rawa (e whakaora ana i te 30% te kaha).
> Note: I roto i te hanga tūturu, me whakarite te pāmahana calendering me te tere roera kia rite ki te rerenga o te tauira (whakarewa MFI taupū = 3-8g/10min) ki te karo i te paheketanga (taupū kōwhai ΔYI <2).
