Uhlelo lwe-Quasi MDI-olunqanyuliwe
Isistimu ye-Quasi MDI-STIDANED PTMG
Ukufanisa
Isakhi:I-DY2513 iqukethe izakhi ze-ABC. Ingxenye A yi-polyol, b yi-polyurethane prepolymer ephethwe yi-isocynate, c yi-chain eyender.
Isimilo:Umkhiqizo wokugcina uthokozela amandla okumelana kahle alwa ne-anti anti, ukubuyela okuhle. Futhi ubulukhuni bungashintshwa ngesilinganiso esihlukile. Umbala ungashintshwa ngombala.
Isicelo:Lokhu kusetshenziswa kwasetshenziswa ukukhiqiza ama-polyurethane sieves, ama-pu roller, ukuhlanza izingulube (ama-disc) kanye nabanye abakwa-elastomer.

I-Quasi MDI-Shered Polyester System
Ukufanisa
Kusetshenziselwa ukukhiqiza ama-polyurethane sieves, ama-pu roller kanye nabanye abakwa-elastomer. Kufanele icutshungulwe ngumshini wokuphonsa amazinga okushisa maphakathi.
Umkhiqizo wokugcina uthokozela amandla okumelana kahle alwa ne-anti anti, ukubuyela okuhle. Futhi ubulukhuni bungashintshwa ngesilinganiso esihlukile. Umbala ungashintshwa ngombala.
Isicelo: Izimoto zezimoto, abahlanza amapayipi, njll.

Ukulawula okuzenzakalelayo
Ukukhiqizwa kulawulwa ngohlelo lwe-DCS, futhi ukupakisha ngomshini wokugcwalisa othomathikhi. Iphakheji yi-200KG / DRUM noma i-20kg / Drum.
