The present disclosure is directed to a formulations of cements and methods for bonding dissimilar materials. The formulations and methods can bond a Non-polyvinyl chloride (PVC) containing first polyolefin that is amorphous or has low crystallinity to a second material that is a rigid material or a hard PVC. The methods and formulations can work by co-dissolution at an interface, or activation of a one of the materials prior to bonding.

A method for producing a decorative floor covering comprises digitally printing an adhesive on a printing substrate thus generating an adhesive layer forming an at least one-dimensionally patterned decorative motif. The adhesive is a radiation-curable composition, preferably essentially free from non-reactive solvents and/or from photoinitiator. The printing substrate includes one of a core structure and a wear layer. After the printing of the adhesive, the adhesive layer on the printing substrate is contacted with the other one of the core structure and the wear layer. The core structure and the wear layer are then attached to each other by electron-beam curing the adhesive layer between them.

The present invention relates to a method for evaluating an assembly by welding of parts made of thermoplastic materials, to a test piece and its associated uses, to an installation for implementing this method and to the associated welding system.

This invention discloses a production method of inflatable toy. The first step is to prepare hard PVC powder and soft PVC paste resin. The second step is injection moulding of embedded parts and grasp parts. The third step is preparation of slushing mold or rotational molding mold. The fourth step is shaping of soft PVC paste resin. The fifth step is cooling and demoulding and then air inflation for modeling. The sixth step is installation of grasp parts and inspection and testing of qualified products; in this invention, the secondary forming of hard PVC embedded parts made through injection moulding, are moulded in soft PVC rubber part itself through rotational molding or slush molding in the rotational molding mold or slush molding mold. And then, the grasp parts and embedded parts are firmly connected through buckle or screw. The design has solved the problem of location design of the circular handle, which is unable to be installed in parts other than the joint line through traditional PVC rotational molding mold or slush molding mold. It has perfectly realized the grasp function. In addition, the installation of formed ears or other injection-moulding parts guarantees no deformation of the parts, and this presents a good revivification of product design.

A method for bonding thermoplastic fiber-composite parts comprises providing surface texture on one or both parts being bonded, and/or providing both parts with engagement features. Such surface textures and engagement features have a specific geometry and fiber alignment that facilitate fibrous interlock between the two parts at a bonding interface via in-situ consolidation.

A vent structure for large volume liquid storage tanks having a double gooseneck shape with vent openings facing downward, formed as a single structure from a mold tool with multipart extractable cores for forming the structure from corrosive resistant materials without a need for substantial post machining.

A two-piece connection between a supply pipe from a source of water and a connection to a fire sprinkler with the connector having a first or rear section entirely above a ceiling and a second or front section connected to the first section with the connection entirely above a ceiling and the forward portion of second section connected to the fire sprinkler. The first connector section, located entirely above a ceiling, has a spherical male sidewall with a rounded leading edge and a rear portion of the second connector section has a spherical female interior surface.
