Izinkuni zepholiyofothi zepolyurethane D/DE
Izinto ezibalulekile
1、Ukubanjiwe kakhulu, ukuhlawulwa okuncane, ukuphila okuningi kwezinyanga;
2、Ubunzima 0.4～0.7g/c m³ okuyizinkuni ezibalekayo, ubukhulu bokuphila kwesikhathi esiself-skinning 4～6mm;
3, isimo sokwenziwa kuyisimo esihambisanayo, sisebenzisa ukubambisana + ukufakwa kwezinkuni zokufaka okukhethiwe.
