Looxa dahaarka dab-demiska oo wax laga beddelay
Gudida dahaarka dab-demiska ee wax laga beddelay waa jiil cusub oo ah dahaarka kulaylka, dab-demiska iyo walxaha dahaarka dhawaaqa.Maaddadu waxay leedahay faa'iidooyinka caabbinta ololka wanaagsan, qiiqa qiiqa hooseeya, waxqabadka heerkulka sare ee xasilloon, kuleylka kulaylka, xakamaynta dhawaaqa, iyo adkeysiga xooggan.Maaddadu waxay si adag u xakameysaa nuxurka biyaha, maadada phenol, maadada aldehyde, dareeraha, xawaaraha daaweynta iyo tilmaamayaasha kale ee farsamada ee resin phenolic si loo gaaro horumar la taaban karo ee dabacsanaanta, adhesion, caabbinta kulaylka, caabbinta ablation, iwm. Noocyo cusub.Sifooyinkan xumbo phenolic waa hab wax ku ool ah oo lagu hagaajinayo badbaadada dabka ee derbiyada.Sidaa darteed, xumbo phenolic ayaa hadda ah sheyga ugu habboon ee ku habboon si loo xalliyo badbaadada dabka ee nidaamyada ilaalinta derbiga dibadda.
