Looxa dahaarka dab-demiska oo wax laga beddelay

Sharaxaad Gaaban:

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.Astaamahan 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 hababka ilaalinta derbiga dibadda.

Tilmaamaha Waxqabadka Alaabta

Guddiga dahaarka xumbo phenolic, noocan oo kale ah guddiga dahaarka xumbo phenolic ayaa la sheegay in ay si gaar ah u sixir, ma aha oo kaliya ka ciyaari kara doorka dahaarka, laakiin sidoo kale ka ciyaari kara doorka ka hortagga dabka.
Dhab ahaantii, guddiga dahaarka xumbo phenolic waa xumbo adag unug xiran oo laga sameeyay xabagta phenolic, ololka celisa, qiiqa joojiya, wakiilka daweynta, wakiilka xumbo, iyo waxyaabo kale oo lagu daro iyada oo loo marayo qaaciidada sayniska.Faa'iidada ugu caansan waa ilaalinta dabka iyo ilaalinta kulaylka

Boodhka-codsiga xumbada dahaarka ee phenolic

Maadaama ay labaduba yihiin xumbo polystyrene iyo xumbada polyurethane ay yihiin kuwo guban oo aan u adkaysan karin heerkulka sare, waxaa xaddiday waaxda dab-damiska ee wadamada warshadaha horumaray.Goobaha leh shuruudaha ilaalinta dabka ee adag, waaxyaha dawladdu waxay si cad u qeexeen in looxyada dahaarka ee phenolic kaliya la isticmaali karo.

Sidaa darteed, maaddada xumbo phenolic waa wax-qabad heersare ah oo ku habboon in loo isticmaalo xaaladaha deegaanka ee adag oo leh rajo horumarineed oo wanaagsan.Sida goobo-dhismeedyo dhismeed bir ah, goobo warshadeed oo waaweyn, guryo guurguura, bakhaarro qabow, goobo nadiif ah, dhismayaal lagu daro, guryo ku meel gaadh ah, goobo jimicsi, dukaanno waaweyn iyo dhismayaal kale oo u baahan ilaalinta dabka iyo dahaarka.
