    摘要： A method of forming a polyurethane article wherein first and second components of a polyurethane system are sprayed into an unconfined space above a mold. The first and second components are sprayed together to mix initially in the space above the mold and then are deposited in the mold on an in-mold coating that was previously applied to the mold. The two components of the polyurethane system and in-mold coating are subsequently removed from the mold as a flexible polyurethane skin. The skin may then be placed in a second mold along with a reinforcement. Structural polyurethane foam may then be injected to the second mold where it bonds to the reinforcement and the skin to form a finished polyurethane article having a flexible skin adhered to its surface. A post-mix spray nozzle assembly is provided with a central nozzle forming a first hollow conical spray pattern and a coaxially aligned annular nozzle forming a second hollow conical spray pattern. The first and second hollow conical spray patterns intersect in space remote from the nozzle and form a hollow circular spray pattern.

    摘要翻译： 一种形成聚氨酯制品的方法，其中聚氨酯体系的第一和第二组分被喷射到模具上方的无侧限的空间中。 将第一和第二组分喷涂在一起，最初混合在模具上方的空间中，然后在模具中沉积在预先施加到模具上的模内涂层中。 随后将聚氨酯体系和模内涂层的两个组分作为柔性聚氨酯表面从模具中去除。 然后可以将皮肤与增强件一起放置在第二模具中。 然后将结构聚氨酯​​泡沫注入到第二模具中，其中它与增强物和皮肤结合，形成具有粘附在其表面上的柔性皮肤的成品聚氨酯制品。 后混合喷嘴组件设置有形成第一中空锥形喷雾图案的中心喷嘴和形成第二中空锥形喷雾图案的同轴对准的环形喷嘴。 第一和第二中空锥形喷雾图案在远离喷嘴的空间中相交并形成中空圆形喷雾图案。

    摘要： A fluid delivery system is provided as a modular system. The fluid delivery system provides a fluid to a robotic spray applicator system that may be used to spray a mold with a motor release compound or in-mold coating. The fluid to be dispensed is contained in the drum and is provided through a fluid circuit including a peristaltic pump, a filter and a heater. The fluid is pumped through the fluid circuit to an applicator that dispenses the fluid onto a mold. The system may also be used in conjunction with adhesives or other compositions that must be filtered, heated and provided to a spray applicator at a metered flow rate. The fluid delivery system may be used in conjunction with a robotic system. The displacement of the peristaltic pump may be controlled by a variable frequency drive or may be controlled by a programmable logic controller of the robotic system.

    摘要： A method of cooling a PVC dry blend powder in a vessel by spraying a liquified inert gas into the vessel such that the liquified inert gas contacts the powder. The PVC dry blend powder is made by mixing a powdered PVC resin with ingredients selected from the group consisting of plasticizers, stabilizers, and pigments in a mixing vessel by using a heating and mixing cycle followed by a liquified inert gas cooling cycle. The flow properties of PVC dry blend powder made by this method have an improved shelf life.
