Taking The Veil Off Facades: The Different Choices For You

There is a lot that you need to do when making an architectural design – right from the die drawings to complete the calculations for the façade system accurately. Yet, what are the different types of façade choices out there? Here is a look.

A Little Slice Of History

Facades have been around in one form or another since the seventeenth century. Back in that age they were made of huge detailed rocks and logs of wood. The huge structure, labor and expense made the use of facades confined to buildings like churches and other huge pieces of architecture. Facades have come a long way these past few centuries, become more modern and innovative.

The Story Of Development

Facades have been developed to a level where it is used for several other purposes than just being decorative or as a representative of your wealth. They have been grown into being weather proofing and control systems. These have become more popular today as they are highly energy efficient. The materials used include aluminum, zinc, copper, glass or titanium.

There are three major types of façade systems implemented commonly today

  1. Q-Ventilated Façade Systems

This system is basically a derivative of the Terracotta rainscreen installation system. It uses a double wall design that enables the outer layer to keep away the water and the inner layer maintains the thermal insulation.

It’s important because it helps in maintaining the ventilation and keeping out even the smallest amount of moisture. There is a drainage system that removes the excessive water. There are no floor slabs to create any sort of interruptions thus taking away the possibility of thermal bridging and temperature fluctuations.

  1. Q-Insulated Façade Systems:

 There are essentially two metal reinforced layers that are very flexible and are combined using an insulation core. It is highly resistant to fire. The preferred metal used is aluminum, especially due to its versatility that allows it to be used for various different functions.

  1. Q-Linex Façade Systems:

The simplest form, where all the remaining ones were made of more than one component fixed together with some sort of hinge of insulation. This system is a single panel that is attached to a secondary support system which is essentially a part of the house or building. The panel dimensions depend on the necessity.

The thickness of the material used depends on the width of the system needed. The material used can vary from aluminum, zinc, stainless steel and even alloys.

Choosing the Right Design

Today, facades are important like never before. The progress made in this field is the combined effort of a bunch of people who felt intrigued by the design of facades and strived to constantly push the limits of perfection and efficiency

The aim has always been to create the most practical but beautiful façade, you are always welcome to choose your façade from Telling Architectural Facades, acclaimed for their dedication to perfection.

Industrial degreasing techniques: etching

Reducing energy costs and improving the ecological purity of the materials remain the most problematic issues of degreasing surfaces. As practice shows, the existing degreasing water compositions at low temperatures (25-30 ° C) do not not provide the high quality of the surface cleaning. Decent results are likely to be achieved only with the use of organic solvents and emulsion formulations, but it negatively affects the environment. The contradiction is removed to a certain extent in the application of thermal degreasing methods, but it is not always a panacea for certain financial reasons. Such options as the use of compositions which do not require subsequent washing (for example, BOC-5) or allow discharging wash water without pre-cleaning can be considered, but hardly possible to resort to.

Etching technology

Scale, rust and other oxides are often removed from the metal surface by etching in solutions of acids, acid salts or alkalis. Cleaning the surface with etching method is reduced to the dissolution of the surface layer of oxides and metal recovery of oxide compounds and the separation of hydrogen generated. Etching products are subjected to pre-purified from mechanical impurities and fat.

Etching in ferrous metals

As etchants for ferrous metals the most commonly used materials are sulfuric, hydrochloric and phosphoric acid with various additives. In acid etching the kinetic curve to reduce the mass of the sample can be divided into three periods: dissolving oxides, the appearance of the anode surface areas, accompanied by the simultaneous dissolution of oxide and metal and dissolution of metal.

Sulfuric acid reacts more actively to iron than with its anhydrous oxides (by etching dissolves no more than 20% of the scale). Getting into the pores and cracks of scale, the acid dissolves the surface layer of the metal and thereby violates its relationship with the scale. Therefore, in the etching sulfuric acid is associated with the formation of a significant amount of sludge hydrogenation steel. The metal surface as a result of etching can have a highly uneven relief. The most frequently used acid concentrations vary from 150 to 200 g/l, the etching process is carried out at 50-80°C.

The hydrochloric acid descaling occurs primarily as a result of dissolution (weight reduction of scale is 50% or more). Consequently, the metal surface after etching in hydrochloric acid is smoother than in sulfuric one: the degree of sludge formation is also reduced. Etching in hydrochloric acid is conducted at temperatures of 20-60°C, optimum acid concentration of 100-150 g/l. The use of hydrochloric acid, however, is less convenient and economical than sulfuric acid. Therefore, etching oftentimes implies using sulfuric acid and mixtures of sulfuric acid with hydrochloric acid or sodium chloride. The presence of the latter reduces the corrosion rate of iron without affecting the dissolution rate of an oxide. An even more effective in this respect is the introduction of the composition of the etching solution of corrosion inhibitors (additives) represented by methenamine, and others.

A way more cost-effective technology, demanding considerable engineering and financial efforts, but paying off in the long run, can be ultrasonic cleaning. Pioneered by the industry innovators like Hilsonic, a far-famed ultrasonic cleaner equipment manufacturer, has recently presented a cost-effectiveness report on projects implemented in 2015, boasting impressive financial feasibility ratings.
