摘要:
This coating device comprises: a rotatable coating bar (1) that is arranged inside a container (34) having a coating fluid inlet and an upper opening; a plurality of pairs of rotatable supports (2a, 2b) that are arranged intermittently along the longitudinal direction of the coating bar (1), and that support the coating bar (1) from below; and a weir (37) that is located close to the outer periphery of at least the support (2b). The positional relationship between the support (2b) and the weir (37) is determined such that, if a line that connects the shaft center (13b) of the support (2b) and a point (A) which is the end edge of the weir (37) and which is closest to the support (2b) is defined as a straight line (L1) and if a point where the straight line (L1) intersects with the outer periphery of the support (2b) is defined as an intersection point (B), a straight line (L2) that is perpendicular to the straight line (L1) and that passes through the midpoint of a line segment (AB) does not intersect with the coating bar (1). With this construction, it is possible to suppress ripples on the fluid level inside the container caused by an accompanying flow, and also prevent air bubbles from being entrained and accompanied at the coating section.
摘要:
The invention provides a method of applying a powder coating to a surface of objects (10), in particular heat sensitive objects. The method uses a coating powder which when heated to a first temperature (T1) assumes tacky properties, and when heated to a second temperature (T2) higher than the first temperature (T1) will cure. The method comprises applying heat to the surface of the object (10) so as to heat a first surface layer of the object to the first temperature (T1); applying the coating powder to the heated surface of the object (10); and applying heat to the surface of the object (10) so as to heat a second surface layer of the object (10) and the applied coating powder to the second temperature (T2). The method is particularly useful for powder coating objects (10) comprising heat sensitive materials such as wood, medium-density fibre board, gypsum and plastics.

The invention permits the production of bubble-free solder resist coatings on circuit boards with high and closely spaced conductor tracks by using a solvent-free photopolymeric lacquer which is heated to pouring consistency by passage over a heated roller with a doctor blade and under an infrared lamp and then poured in the form of a curtain over the cooled circuit boards.
摘要:
The present invention relates to coating compositions, processes for making them, and methods of application of the coating compositions. Further, the present invention relates to a process and apparatus for coating a metal substrate, for example an elongated metal tubular substrate such as a pipe. Most particularly, the coating can be used as an anti-corrosion coating on a pipe for use in oil, gas and water pipeline applications.

A procedure for the application of a seal (3) onto a surface of a device housing (1,2) for a motor vehicle, especially a motor vehicle door lock housing surface, comprising the following procedural steps: the surface is at least partially cleaned and/or micro structured by a heat source (4) restricted in area; and a sealant is applied to areas of the surface treated in such a way.
摘要:
Es sind eine Fügeflächenvorbehandlungsvorrichtung (20) und ein Fügeflächenvorbehandlungsverfahren bereitgestellt zur Vorbehandlung einer Fügefläche (TO) eines Bauteils (4), die zum Zusammenfügen zweier Bauteile (4,5) dient. Die Fügeflächenvorbehandlungsvorrichtung (20) hat eine Wärmequelle (28; 29; 22; 24) zur Erwärmung eines Teils (TO) einer Oberfläche eines ersten Bauteils (4), an welchem das erste Bauteil (4) an ein zweites Bauteil (5) gefügt werden soll, und eine Primerauftrageinrichtung (23) zum Auftrag eines Primers (P) auf einen von der Wärmequelle (28; 29; 22; 24) erwärmbaren Teil (TO) der Oberfläche des ersten Bauteils (4), wobei die Wärmequelle (28; 29; 22; 24) derart angeordnet ist, dass sie das erste Bauteil (4) vor und/oder nach dem Auftrag des Primers (P) erwärmen kann.
摘要:
Methods and associated compositions are described for applying onto a substrate a cured coating that includes at least one layer of a water-borne basecoat and one layer of clearcoat and that requires a maximum total curing time of less than about 45 minutes. Further described are methods and associated compositions for applying onto a substrate a cured coating that includes at least one layer of primer, at least one layer of a water-borne basecoat and at least one layer of clearcoat and that requires a maximum total curing time of less than about 65 minutes.
