FRP~浴缸裂縫 修補填縫劑建議 - Yahoo!奇摩知識

FRP~浴缸裂縫要修補，有哪一種膠可以修補填縫?
當然只有FRP用的環氧樹脂最適當了，同樣的材質接著最強了。
價格便宜，容易購買(台北市天水街一連好幾家)化工行都有在賣。
只是修補用，買小瓶裝的就夠用了(再加一小段的玻璃纖網布)。
一般FRP~浴缸會產生裂縫:原因有二:
一:FRP在製成時是用(積層法)將不規則玻璃纖蓆一層一層黏貼上去，由於是大量製造。在積層時氣泡有些還沒消除就再上一層，造成中空或脫層的現象，強度自然就不夠，若施重壓就很容易有破裂的情形。
二:一般FRP~浴缸會有裂縫最常發生在浴缸底部，因為洗澡時常站立在浴缸內遇到品質有瑕疵的(上述的情形)較容易有裂縫的產生。
浴缸是否有瑕疵，一般人是看不出來的，除非是非常專業的人士。
如何防止上述的情況發生，很簡單只要在裝浴缸時請泥工師父把浴缸底部的水泥砂墊高與缸底接觸到就可以了，就算是有2~300公斤的体重也不怕浴缸垮底了。言歸正傳幫你解決問題:
一:先將浴缸的水排乾，裂縫用吹風機吹乾。
二:看是有一條裂縫，其時有一些細微的裂縫肉眼是看不見的，所以要將裂縫四周圍最少10cm內寬的面層磨除到可以看到玻璃纖維為止。(用80~150的粗砂，第一次很好磨)很快你就可以發現裂縫不止一條。
三:再來將買來的環氧樹脂依比例調合，(分三次用，打底時不要一次調太多100cc就夠了)用小毛刷塗刷磨除後的地方，讓樹脂完全滲入，(有一些會從裂縫流掉)，馬上覆蓋(磨除後面積大小)的玻璃纖網布，第二次調合要多一倍的量(一樣用小毛刷塗刷讓樹脂完全滲入玻璃纖網布，等完全硬化氣溫25~30度硬化時間6~8小時。第二次磨除整形，就不好磨了(看你要求的平整度了)最好是用研磨機具，因為非常硬。
四:研磨完成，就可以塗最後一層了可加顏料色母搭配。完全硬化後保証可再用十年。以上的說明夠清楚了吧。

Hennecke sets up agency in South America

By Urethanes Technology International

Posted 24 September 2009 8:24 am GMT

Polyurethane equipment specialist Hennecke GmbH has established a new agency in South America in cooperation with Argentinean hydraulic press maker Jose Iturrospe SAIC.

The two companies said in a 16 Sept statement that they will cooperate in selling Hennecke products and on qualified technical customer services.

Iturrospe, headquartered in Rosario in the Argentinean Province of Santa Fe, was set up in 1950, and, says Hennecke, has “an excellent knowledge of the market and plenty of experience in the local mechanical engineering sector.” This makes the company an valuable partner for the systematic expansion of the Hennecke sales and service network on the American continent, the company added.

This new agency is a response to the “increasing potential of the South American market and the growing demand for high quality, polyurethane-based

products within the region,” Hennecke management indicated.

The group’s experienced team of sales specialists and technical experts wants to support processors of those products with a broad spectrum of services in the local language and guarantee the shortest possible response times for delivery of plant and machine technology as well as spare parts.

Hennecke and Iturrospe will also pool their know-how in terms of high quality hydraulic presses for the discontinuous manufacture of polyurethane sandwich panels. Within this product group, the new agency covers the whole South American land surface up to the state border of Panama and Cuba.

Iturrospe will offer the complete Hennecke portfolio, except in Brazil, where long-term and competent Hennecke partner RoWe will continue to deal with local customers.

New RIDGID Press Snap Soil Pipe Cutter Provides Fast And Easy Cutting Of Cast Iron Soil Pipe

September 23, 2009

Elyria, OH - The RIDGID Press Snap soil pipe cutter expands the capabilities of RIDGID standard press tools by providing a fast and easy way to cut cast iron soil pipe.

The Press Snap cutter eliminates the need for manual ratcheting when it is connected to a RIDGID press tool. To make a cut, the Press Snap cutter is attached to the press tool, the Press Snap chain wraps around the pipe, and the user presses the trigger to make the cut. There is no need to score the pipe beforehand. The Press Snap cutter cuts most 1-½- to 4-inch no hub and service weight soil pipe. It works with all RIDGID standard press tools, including the CT-400, 320-E, RP 330-B and RP 330-C.

"The Press Snap soil pipe cutter provides additional functionality to RIDGID press tools," said David Roberts, plumbing and pressing technologies. "The new Press Snap cutter enables users to cut soil pipe in seconds with minimal effort."

RIDGID pressing technology consists of electro-hydraulic press tools with interchangeable jaws and rings that press and connect copper, stainless steel, and PEX tubing in seconds.

Hydraulic Press suits prototyping, production simulation.

September 22, 2009 - Dual-action hydraulic press, aided by custom tooling, can produce accurate prototype products for analysis and testing. Its 2-axis design replicates manufacturing operation and produces samples with properties similar to those required in actual production. Built around 20-ton vertical cylinder and 5-ton horizontal cylinder that operate in force-over-time mode as selected in operator interface, press also features electronic controls, 10 in. screen, and Ethernet connectivity.

New 2-Axis Hydraulic Press for Prototyping and Production Simulation

In many high-volume production operations, the synchronized application of vertical and horizontal force on the end product is critical. Pressure must be applied and released from both axes simultaneously and at the same rate. Phoenix has designed a dual-action hydraulic press that, with the aid of custom tooling, can produce accurate prototype products for analysis and testing. The two-axis design replicates the manufacturing operation, and produces samples with very similar properties to those required in actual production. As an example, pharmaceutical scientists determine the proportion of drug compounds and inactive ingredients in medicinal tablets. Prior to volume production, sample tablets produced by the Phoenix press are tested for mechanical properties to minimize development time in the manufacturing process. The heart of the press consists of a 20 ton vertical cylinder and a 5 ton horizontal cylinder. The cylinders operate in a force-over-time mode as selected in the operator interface. The ramp time for each cylinder is 30 to 60 seconds, with a hold time ranging from 5 seconds to two minutes. Pressure is controlled to within ± 5 percent. Electronic press controls include a Delta Motion Controller, Micrologix 1100, and a PanelView operator interface with a 10" screen. PLC/HMI communications are provided through Ethernet connections.

Bosch Rexroth Seminar Offers Roadmap for Reaching Hydraulic Power Press Safety Compliance

Burlington, Ontario

Bosch Rexroth Canada is offering a free Hydraulic Power Press Safety Seminar on September 10, 2009. The seminar will demonstrate how to achieve hydraulic press worker safety that meets exacting regulatory standards, without compromising productivity or cost-effectiveness.

Specific regulations, including the Canadian Standards Association Z142-02 Power Press Safety Standard,will be examined in the context of how they apply to individual users' hydraulic press operations. "Bosch Rexroth has a great deal of experience meeting very strict and complex hydraulic press safety standards in Europe over the last couple of decades, which were the basis for the Canadian standards," explains seminar presenter Steve Storini, Industrial Hydraulics Engineering Manager, at Bosch Rexroth. "That has given our organization a solid foundation of specialized knowledge in terms of meeting requirements and codes, which we will share with our audience."

Specialized safety techniques presented to seminar attendees will include the government-mandated Pre-Start Health and Safety Review procedures and high-level (trended) condition monitoring, including maintenance solutions designed for safe press systems.

The seminar will focus on applying specialized systems, principles, techniques, and components to maximize hydraulic press safety and regulatory compliance. Attendees will learn how devices and equipment such as drive and control systems, energy-saving drives, safety circuits and aluminum framing can contribute to a safer environment for press applications.

Because safety goals must be met within an environment that also demands high productivity, uptime, and cost-effectiveness, the Bosch Rexroth Seminar will emphasize techniques to create safe, compliant machines and processes while maintaining production efficiency.

The Hydraulic Power Press Safety seminar is intended for managers, plant engineers, maintenance specialists, machine builder design engineers, PSR consultants which implement solutions, integrators, and end-users in any industry that uses large hydraulic power presses, including automotive, commercial goods, and others.

Presentations will be accompanied by simulations of press operations, and attendees are invited to bring schematics for evaluation and discussion as time permits. The seminar will take place from 9 a.m. to 3 p.m., with breakfast and lunch included. Hydraulic press safety is just one of many topics covered in the 2009 Bosch Rexroth seminar series. Other topics include Safe Motion, Hydraulic Maintenance, Lean Manufacturing Principles, and Tier 4 Emissions.
