Kutenga Mapepala

Mitundu ya plywood ndi makulidwe, zomwe tafotokoza m'nkhaniyi, zidzakuthandizani kusankha kusankha. Mwachitsanzo, chinthu chotsiriza chingasinthe mamita 3 mpaka 30. Ply imasiyanasiyana ndi ma unit 3 mpaka 21. Choncho, pa zinthu zomwe makulidwe ake ali mamita 27, chiwerengero cha zigawo chidzakhala 19, pamene 9 mm plywood chiwerengero cha zigawo chimasiyana mkati mwa 7.

Kusiyanitsa kumatha kumatha kusiyana ndi 0.4 mpaka 1, 2 millimeters. Chizindikirochi chikukula molingana ndi makulidwe a pepala. Sikofunikira kuti tifunikire, ngati palibe chifukwa chogwiritsira ntchito plywood yokongola kwambiri, zowonongeka sizikanakhala zomveka. Ndichifukwa chake musanayambe kupeza izo mukulimbikitsidwa kuti mudzidziwe nokha ndi chikhomo chomwe chinaperekedwa m'sitolo.
