Q: Yadda za a kauce wa burrs da shafi fatattaka lokacin yankan aluminum hada bangarori alucobond?
A: Maɓallin fasahar sarrafa kayan aiki da kayan aiki: • Zaɓin kayan aiki: ◦ Don gefen gaba na farantin: yi amfani da ruwan lu'u-lu'u (tare da aƙalla 120 hakora, yana juyawa a 3000 rpm) don yanke a kan gefen farantin; ◦ Don gefen baya na farantin karfe: canzawa zuwa babban madaidaicin karfe don hana kullun fata na aluminum. • Gudanar da tsari: ◦ Cire fim ɗin kariya kafin yanke (don kauce wa narkewa da danko); ◦ Yawan ciyarwa ≤ 2 m / min, yi amfani da sanyaya iska don rage lalacewar thermal. Lura: Babu shakka kar a yi amfani da abin yankan dabaran niƙa - tabbas zai haifar da carbonization na murfin PVDF.

Q: Ta yaya za a iya tabbatar da daidaiton machining na bangarori masu siffa (filaye masu lankwasa/kusurwoyi)?
A: Mataki na uku-madaidaicin tsari na tsari: 1. Digital modeling: ◦ Sami bayanan gine-gine ta hanyar 3D scanning → Ƙirƙirar lambar machining CNC (kuskure ≤ 0.1mm); 2. Ƙimar sarrafawa ta lamba: ◦ Surface: Mold forming ta amfani da Multi-point Vacuum thermoforming machine (mai tsanani zuwa 140 ℃ ± 5 ℃); ◦ Kusurwoyi: Yi amfani da injin lankwasawa na hydraulic (matsa lamba 80-100 ton) tare da mold polyurethane; 3. Rage damuwa: ◦ Bayan gyare-gyare, ci gaba da yawan zafin jiki na 25 ℃ na tsawon sa'o'i 24 don kawar da nakasar damuwa na ciki.

Q: Menene ƙayyadaddun fasaha don zurfin da matsayi na tsagi na gefen da aka yi amfani da su don ɓoye masu rataye?
A: Siga 1: Zurfin rami, buƙatun: ≤1 / 2 kauri na takardar aluminum (yawanci 0.3-0.5mm), kayan aikin dubawa: Laser kauri ma'auni. Siga 2: Ramin gefen nesa, buƙatu: ≥15mm (daga gefen farantin), kayan aikin dubawa: dijital vernier caliper. Siga 3: Ramin kasa fillet, buƙatun: R≥0.8mm (don hana damuwa damuwa), kayan aikin dubawa: radius gauge.Dole ne ya dace da ka'idodin aminci na hanyoyi uku, gargadi: wuce gona da iri na iya rage ƙarfin ƙarfin aluminum da 40%!

Tambaya: Me ya sa ya zama dole don ƙara ƙarfafawa a baya na manyan bangarori na filastik aluminum (≥3m)? Yaya ake yi?
A: Dalili: Don hana lalacewar yanayin girgizar da iska ta haifar da lalacewa (ƙimar karkatarwa dole ne ≤ L / 180). Tsarin ƙarfafawa: 1. Abu: Aluminum alloy T-dimbin keel (kauri ≥ 2.0 mm); 2. Adhesion: Aiwatar da mannen tsarin tsarin epoxy guda biyu (ƙarfin ƙarfi ≥ 8 MPa); Bayan latsawa, yi amfani da nauyin 0.5 kg / cm² don warkewa na sa'o'i 24; 3. Matsayi: Tazarar haƙarƙari ≤ 600 mm, nisa daga gefen ≤ 150 mm.

Tambaya: Yadda za a kare sassan da aka sarrafa don karko?
A: Magani masu mahimmanci guda uku: Tsarin kariya: 1. Edge sealing → Aiwatar ** Epoxy gefen sealant ** (ya rufe tushen aluminum, yana hana shigar da danshi) 2. Ƙarfafawar tsagi → allurar ** polyurethane elastomer ** (cika micro-cracks, haɓaka tsagi tauri) 3. Backside spraying spray chrome 3 ≥ 1000 hours) * Sharuɗɗan karɓa: gefen hatimi Layer kauri ≥ 0.2mm, babu wuraren da aka rasa / kumfa (wanda aka gano ta hanyar ganowar UV). ◦ CNC saurin tsagi: mita 30 a minti daya (kayan aikin hannu 3 mita a minti daya); • matakai na musamman: ◦ Perforation na bangarori masu watsa haske: yankan ruwa (rami diamita ≥3mm, density ≤15%); ◦ Tasiri mai kama da dutse: embossing surface + UV bugu (jin juriya na yanayi ≥8). An bayar da aikin samfurin kyauta → Tabbatar da dacewa da tsari!
