EVA Waterproof Board—Flexible EVA Impermeable Mapepala

1.Kuchita Kwapamwamba

EVA, chidule cha ethylene-vinyl acetate copolymer, ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri. Makhalidwe ake amaphatikiza kusinthasintha kwabwino, kukana kuvala, kukana kukhudzidwa, komanso kuchita bwino kosalowa madzi. Gulu la EVA lopanda madzi limawonetsa mphamvu zolimba ≥16 MPa ndi elongation ≥550%, zomwe zimatha kupirira zosiyanasiyana zachilengedwe.

2. Kusintha kwazinthu Zapamwamba

Gulu lathu la EVA lopanda madzi limapangidwa makamaka kuchokera ku polima wosinthika wa EVA wokhala ndi zosankha za makulidwe (0.8-2.0mm) ndi njira ya m'lifupi (1-4m), kutengera momwe mungagwiritsire ntchito, timapereka kukula ndi masinthidwe osiyanasiyana.

3. Yomanga-wokometsedwa unsembe

Bolodi lopanda madzi la EVA limatha kudulidwa mosavuta, kupangidwa ndi kutentha, ndikusinthidwa malinga ndi kapangidwe kake pomwe ikuwonetsa kukhazikitsa ndi kukonza kosavuta, ndikufulumizitsa nthawi yantchito. Chifukwa chake, bolodi lopanda madzi la EVA limatha kusinthika moyenera kuzinthu zovuta zomanga.
