Kalkulator Litupan Salutan WFT/DFT

Kira balik ketebalan filem basah dan penggunaan bahan sebenar daripada sasaran ketebalan filem kering, pepejal isipadu, kadar kehilangan dan keluasan.

Switch between microns and mils while working through industrial salutan stages, including heavy-duty salutan jobs.

See DFT, WFT, theoretical litupan, and usage in one place
Menyokong mikron / mil dan m²/L / ft²/gal
Mengendalikan bahagian keluasan untuk lapisan jalur dan pembaikan setempat

Cara menggunakan

  1. Pilih sistem unit.
  2. Masukkan DFT sasaran, pepejal isipadu dan bilangan lapisan untuk setiap peringkat.
  3. Tambah area, loss rate, and area kongsi if needed.
  4. Review WFT, theoretical litupan, and actual usage.
  5. Salin the hasil or kongsi the semasa keadaan if needed.

Sampel

Two-stage heavy-duty salutan (metric)

Input Area 100 m², loss rate 10%, Primer: DFT 75 µm, volume solids 80%, 1 coat, area kongsi 100%, Topcoat: DFT 50 µm, volume solids 65%, 2 coats, area kongsi 100%

Output Primer WFT 93.75 µm, theoretical litupan 10.67 m²/L, usage 10.42 L. Topcoat WFT 76.92 µm, theoretical litupan 13.00 m²/L, usage 17.09 L. Total 27.51 L.

Partial salutan with stripe coat (imperial)

Input Area 10,000 ft², loss rate 10%, Stripe coat: DFT 3 mil, volume solids 80%, 1 coat, area kongsi 25%

Output WFT 3.75 mil, theoretical litupan 427.78 ft²/gal, effective litupan 385.00 ft²/gal, actual usage 6.49 gal.

Formulas

  • WFT = DFT ÷ solidsFraction
  • Theoretical litupan = 1000 ÷ WFT(µm)
  • Theoretical litupan = 1604.1666667 ÷ WFT(mil)
  • Penggunaan sebenar = Area × AreaShare × Coats × DFT ÷ (1000 × solidsFraction × (1 - lossRate))
  • Jumlah DFT peringkat = DFT × Coats

Glossary

DFT

Dry film thickness kiri after curing. This is the main figure used in specifications and inspection criteria.

WFT

Ketebalan filem basah sejurus selepas aplikasi. Hanya pepejal yang kekal selepas pengeringan.

Pepejal isipadu

The kongsi of volume that remains as film. Use volume solids for thickness conversion.

Theoretical litupan

A tiada-loss litupan anggaran derived from WFT.

Area kongsi

The kongsi of total area assigned to a stage, such as stripe coat or touch-up work.

Catatan

  • Kalkulator ini menggunakan pepejal isipadu, bukan pepejal berat.
  • Kadar kehilangan ialah model ringkas yang berbeza mengikut semburan berlebihan, bahan tertahan pada alat, baki dalam bekas dan keadaan tapak.
  • Area kongsi can be set per stage. It works well for stripe coat and touch-up work.
  • Penggunaan sebenar berbeza mengikut prosedur pengeluar, kaedah aplikasi, suhu, kelembapan dan keadaan substrat.

Soalan Lazim

Apakah perbezaan antara WFT dan DFT?

WFT is the film thickness kanan after application, while DFT is the film thickness kiri after drying. Volume solids are used to convert between them.

Adakah pepejal isipadu dan pepejal berat sama?

Tiada. Use volume solids for thickness conversion. If you only have weight solids, convert them separately first.

Apakah kadar kehilangan yang patut saya masukkan?

Use a nilai that matches the application method, geometry, and your medan experience. Higher overspray usually means a higher loss rate.

Bolehkah saya menggunakannya tanpa memasukkan keluasan?

Yes. Leave area blank if you only need the WFT and theoretical litupan calculation.

Bolehkah saya mencampurkan unit metrik dan imperial dalam satu pengiraan?

Tiada. Keep the entire calculation in one unit system at a masa.
