    • PURPOSE: Provided are method for reforming thermoplastic thin sheet, its device and system. CONSTITUTION: A thermoplastic sheet, such as solid surface laminate material(SSL) is postformed to a substrate having a planar surface and an edge with a desired profile, by heating a portion of the thermoplastic sheet proximate to the edge. Adhesive attaches the thermoplastic sheet to the planar surface and edge of the substrate. The adhesive is solvent-based contact adhesives or water-based specialty adhesives. The composite formed by the attached thermoplastic sheet and substrate is used for counter-tops, vanity tops, bath and shower surfaces, furniture surfaces and the like. Heating of the portion of the thermoplastic sheet is by focused line heating, conventional heating and a heat shield, a combination of focused heating and conventional heating, or by just conventional heating. The heated portion of the thermoplastic sheet is preferably between about 275 (135) and 320 (160) degrees Fahrenheit ( DEG Celsius) before bending. An optional protective film may be placed over the front side portion of the thermoplastic sheet being heated to minimize surface defects thereto.
    • 目的:提供热塑性薄片,其装置和系统的重整方法。 构成:通过将热塑性片材的一部分靠近边缘加热,将诸如固体表面层压材料(SSL)的热塑性片材后成型为具有平坦表面和具有所需轮廓的边缘的基材。 粘合剂将热塑性片材粘附到基材的平坦表面和边缘。 粘合剂是溶剂型接触粘合剂或水性特种粘合剂。 由附着的热塑性片材和基材形成的复合材料用于台面,梳妆台,浴室和淋浴表面,家具表面等。 通过聚焦线加热,常规加热和隔热罩,集中加热和常规加热的组合,或仅通过常规加热来加热部分热塑性片材。 在弯曲之前,热塑性片的加热部分优选在约275(135)和320(160)华氏度(摄氏度)之间。 可选的保护膜可以放置在被加热的热塑性片材的正面部分上,以使其表面缺陷最小化。
