Waa maxay sababta casters-ka polyurethane aysan u waarin marka ay ka tagaan waqti dheer

Badanaa macaamiishu waxay na waydiiyaan casters polyurethane oo la dhigo wakhti dheer, gabowga ayaa dhici doona, si sahlan loo jebin karo iyo ifafaale kale, dhab ahaantii, tani maaha dhibka caster, taas oo ah dhacdo caadi ah.

Marka hore, polyurethane caster sababaha gabowga
Sababaha gabowga ee poliurethane caster way kala duwan yihiin.

Marka labaad, saameynta gabowga ee caster-ka polyurethane
Polyurethane caster gabowga, sifooyinka jidheed iyo kiimikaad ayaa isbeddeli doona, oo u muuqda midab madow, dildilaaca dusha sare, hoos u dhaca qallafsanaanta, yaraynta barti. Iyadoo sii xumeynta heerka da'da, waxqabadka poliurethane casters ayaa si tartiib tartiib ah u lumin doona shaqada, ugu dambeyntiina u horseedda fashilka alaabta.
