Nhanganyaya kune Polyamide Adhesives

Epoxy-zvinonamira zvepolyamide, zvakagadzirwa ne epoxy resins, zvine cheni dzekabhoni dzine fatty refu, zvichiita kuti pave nechigadzirwa chakaomarara asi chisiri{1}kupora. Ivo vane zvishoma kuomesesa kusanganisa zvinodiwa, hupenyu hurefu hwepoto, uye zviri nyore kushandisa. Zvinoratidza kunamira kwakasimba, zvichiratidza kushanda kwakanaka kwesimbi kune dzakawanda dzisiri-simbi. Chigadzirwa chakarapwa chine kushomeka kwakadzikira (kuderera kana kusatombo{{6}kusiri muchetura), zvichiita kuti inamire inoenderana nenharaunda. Kupisa kunogona kukurumidza kuporesa uye kuvandudza simba rezvisungo; kurapa pa 120 dhigirii kwemaminitsi makumi matatu zvakaenzana nemazuva manomwe patembiricha yekamuri. Zvisinei, kupikisa kwayo kupisa kwakaderera, nepamusoro pekushanda kwekushisa kwe60 degrees.

Yakaderera{{0}molecular-huremu hwepolyamide kurapa mishonga inogara ichivandudzwa, nemhando dzinosanganisira yakaderera-kuona, kuona, kukurumidza{{3}kupora, yakakwirira-kunamira, uye mvura-marudzi. Vamwe vanogona kuwana simba rekusvuura rinopfuura 10 kN/m kune epoxy adhesives, inodarika yakapetwa kashanu yeakajairika aliphatic amine kurapa maajenti.

Kunyange zvazvo epoxy-zvinonamira zvakaderera molecular weight polyamide zvine kusimba kwakanaka, kusimba kwebhondi yemasisitimu asina kuomesa zvinhu hakuna kukwirira. Semuenzaniso: 100 zvikamu (kuburikidza nekurema) kweE-51 epoxy resin, 50 zvikamu zve 651 polyamide, 50 zvikamu zvechiedza calcium carbonate, 2 zvikamu zveDMP-30, uye 1 chikamu cheKH-550. Kurapa pa 80℃kwemaawa matatu. Iyo tembiricha yekamuri yekugera simba resimbi yakasungwa ndeye 18.2 MPa.
