본 발명은 수전금구 본체의 제조방법에 관한 것으로서, 양측으로부터 온수유로(12a)와 냉수유로(14a)가 마련되고, 냉,온수유로를 통합하는 물 배출구(16a)가 마련되며, 상부에는 유로를 차단하기 위한 밸브(V) 및 밸브를 조정하기 위한 레버가 구비된 수전금구 본체(10)의 제조방법에 있어서, 상기 수전금구 본체(10)는, ABS수지에 유리섬유가 혼합된 소재로서 각 부분을 분할 성형하되, 상기 밸브(V)가 설치되는 기준몸체(11)와, 온수유로(12a) 및 연결조립부(12b)가 형성된 제1조립체(12)와, 냉수유로(14a) 및 연결조립부(14b)가 형성된 제2조립체(14)와, 물 배출로(16a) 및 연결조립부(16b)가 형성된 제3조립체(16)로 나뉘어 성형한 다음, 연결조립부(12b, 14b, 16b)를 상호 조합하는 단계(S10); 조합된 상기 기준몸체(11), 제1 내지 제3조립체(12,14,16)의 외부에 190 내지 210℃로 용융된 ABS수지 조성물을 덧씌우는 형태로 각각의 외부 성형체(22)를 이중으로 사출성형하는 단계(S20); 외부 성형체(22)의 외표면 손상을 방지하기 위해 니켈크롬을 도금처리하는 단계(S30);로 이루어 것을 특징으로 하는바, 부식에 강하고 변형이 적은 ABS수지와 유리섬유를 혼합한 소재로 기준몸체 및 제1 내지 제3조립체를 사출성형하고, 그 외측에는 단일 ABS수지 조성물 소재로서 외부 성형체를 이중사출함으로써, 기준몸체 및 제1 내지 제3조립체에 대한 합체성이 뛰어나 내구성을 가짐과 동시에 수전금구의 무게는 기존 황동재질로 제작되는 일반 수전금구에 대비하여 4분의 1로 현저히 줄여 제작원가 절감 및 판매비용을 낮추어 줄 수 있으며, 수지에 대한 사출성형과 니켈크롬 도금으로 제작되기 때문에 작업공수가 현저히 줄어드며, 좀더 다양한 수전금구의 제작가능한 이점을 제공한다. 아울러 본 발명에 따른 수전금구 본체의 제작은 기존의 황동소재를 전혀 사용하지 않는 이유에서 황동재질의 주물성형에 따른 열악한 환경을 개선할 수 있으며, 수전금구로서 적용 사용시 유해성분이 검출되지 않는 이점이 따른다.
摘要:
L'invention concerne un procédé de réalisation d'un ensemble plan- vasque (19), dans lequel : - on réalise une découpe dans un plan récepteur (1) laissant subsister un liséré (6) de couche (3) stratifiée en surplomb vers l'intérieur de la découpe, - on réalise, à partir d'une feuille mince de matériau(x) synthétique(s) thermoplastique(s), dit film décor, une préforme (10) de la vasque comportant un rebord (11) plan le long de son contour, vers l'extérieur de la préforme, ledit rebord présentant une largeur inférieure à la largeur du liséré (6) de couche stratifiée, - on installe la préforme (10) et le plan récepteur dans le moule de façon à ce que la préforme soit insérée dans la découpe ménagée dans le matériau support et que le rebord (11) plan de la préforme vienne au contact du liséré (6) de couche stratifiée, - on referme le moule et on injecte un second matériau synthétique thermoplastique, dit matériau injecté (15), entre la coquille concave et la préforme. L'invention concerne également un plan-vasque (19) dans lequel la vasque (18) est affleurant au plan récepteur (1).
摘要:
The present invention is directed to a process of thermoforming an acrylic polymer containing sheet by heating the sheet in a mold which comprises (a) a foam which would degrade if in contact with the heated sheet and (b) a thermal barrier which is intermediate the sheet and foam to prevent the foam from degrading. In many applications, the resulting article can be used without removal of the foam. Also, the foam can serve to protect the acrylic sheet such as during long distance shipping. The present invention is also directed to a mulitlayered article.
摘要:
A composite material includes a polymer matrix material and filler material that includes vitreous china. The composite material has a water absorption of less than about one percent. Such a composite material may be used in the production of articles such as sinks, bathtubs, shower receptors, and other articles that may benefit from low water absorption properties.
摘要:
A welded joint for structural component having two or more portions (18, 20) fused together at a weld line (42). An adhesive layer (36) is placed between the two or more portions (18, 20) at the location of the weld line (42) and a conductor (38) is placed between the two or more portions (18, 20) in operable contact with the adhesive. Energy is transmitted through the conductor (38) and into the adhesive layer (36) to activate the adhesive layer (36) and create the weld line (42) that defines the welded joints between the two or more portions (18, 20). The welded joint of the structural component allows energy to be injected into the adhesive (36) layer via the conductor (38) in order to cause the adhesive layer (36) to activate from the inside of the adhesive outward. The conductor (38) can be placed adjacent the adhesive layer (36) or within the adhesive layer (36) in order to cause the adhesive to be activated from the inside outward.
