METHOD FOR APPLICATION OF COATING ONTO BODY ROTATING AROUND AXIS

FIELD: mechanical engineering; application of liquid onto surface. SUBSTANCE: method comes to application of polyurethane forming reaction mixture in the form of screw coils onto body by means of nozzle. Slot head is used as nozzle which is installed at an acute angle parallel to axis of rotation. R...

Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; application of liquid onto surface. SUBSTANCE: method comes to application of polyurethane forming reaction mixture in the form of screw coils onto body by means of nozzle. Slot head is used as nozzle which is installed at an acute angle parallel to axis of rotation. Relative movement between rotating body and slot head and reaction speed of reaction mixture are matched with peripheral speed of rotating body to make screw coils following each other overlap like scales and form gapless connection. EFFECT: increased economy. 6 cl, 4 dwgy
