Kiristaalo cad ama budo kiristaal cad, oo ku milma biyaha, khamriga iyo dareere kale oo dabiici ah. Xalkeeda biyaha waa asiidh.
1,2,3,4-Butanetetracarboxylic acid (BTCA) waa walax dhammaystiran oo aan lahayn formaldehyde oo waara (DP). Waxay leedahay firfircooni sare oo falcelin ah mana laha ur cuncun leh. Iyada oo ay farsamayso BTCA, dharka sida suufka iyo xariirta waxay gaari karaan sifooyin ay ka mid yihiin ka-hortagga joojinta, cadaadiska joogtada ah iyo ilaalinta qaabkooda waxayna leeyihiin adkeysi sare.
BTCA waxaa loo isticmaali karaa in lagu diyaariyo walxaha polyimide. Noocan walxaha ah wuxuu leeyahay iska caabin kulayl oo aad u fiican, iska caabin aashito, iska caabin hydrocarbon iyo sifooyin dahaadh koronto oo wanaagsan, waxaana loo isticmaali karaa in lagu diyaariyo walxo kala duwan oo polymer ah oo shaqeynaya, sida walxaha xasaasiga u ah sawir-qaadista, walxaha polymer-ka caafimaadka iyo walxaha xuubka polymer-ka ee shaqeynaya. Waxaa loo isticmaali karaa in lagu diyaariyo giraangiraha dahaarka korontada, dahaarka siligga iyo walxaha dahaarka korontada.
Bacda warqadda isku dhafan ee 25kg ah oo Polish ah - geed linen ah ama sida uu macaamiishu u baahdo.
Kaydinta:
Ku kaydi meel hadh leh oo hawo leh. Cimrigeedu waa 12 bilood. Wali waa la isticmaali karaa haddii ay kor u kacdo.
Gaadiidka:
Iska ilaali heerkulka sare iyo qorraxdu gubto inta lagu jiro gaadiidka.
