Nolifrit Enamel Frit Exported to Central America

Since the arrival of May, the enamel industry has entered its hot season, and we have received orders for enamel frit from customers in Central America. In recent years, Nolifrit has taken the initiative to develop the international market, actively responding to the “One Belt and One Road” policy, and striving to adapt to the new normal of economic development. The effect of market expansion is gradually emerging. In the past few days, Nolifrit has been working hard to promote production, and all employees have worked hard to ensure the timely delivery. The factory has shown a good situation of both production and sales.QQ图片20190511105942_副本

Coming into the Nolifrit production workshop, one and another converter furnaces is rotating at a constant speed, and the molten enamel frit is then quenched.”This year’s situation is quite well, the current orders has been scheduled to June. In order to catch orders, all of our employees are on duty, and now we are still hiring new employees.” When it comes to the sales situation, the head of the company’s administrative department speaks with proud.QQ图片20190511105954_副本

This batch of enamel frit produced for Central American customers can be delivered on schedule, which is the result of the joint efforts of Nolifrit employees. In order to complete the production tasks with quality and quantity, the company’s leadership is reasonably dispatched and production arranged orderly; the supply department closely tracks and strictly guarantees the timely storage of raw materials; the leaders of the production department are willing to work hard and dedicate. All current production tasks are being carried out orderly. The main products of Nolifrit include nearly 2,000 kinds of enamel ground coat, cover coat, transparent frit, and vitreous enamel powder, inorganic pigment, etc. They are exported to foreign markets, such as Southeast Asia, Middle East, Europe and the United States. The continuous overseas orders fully demonstrates the customer’s acceptance of Nolifrit quality.QQ图片20190511110004_副本

Looking at the container trucks loaded with various enamel frits drive out of factory, the hearts of the Nolifrit people are full of pride. “Let Nolifrit go global” is our unshakable goal. Twenty-three years of history is just like a wave, and now we are developing step by step. We will continue to serve global enamel users with our professional service, excellent work enthusiasm and technical and R&D advantages accumulated for over the past 20 years.

Ceramic Enamel Frit

20190528Available in a variety of colors to harmonize or contrast with the vision area, the ceramic enamel frit is applied to the surface of the glass. Ceramic enamel frits contain finely ground glass mixed with inorganic pigments to produce a desired color. The coated glass is then heated to about 1,150°F, fusing the frit to the glass surface, which produces a ceramic coating almost as hard and tough as the glass itself. A fired ceramic enamel frit is durable and resists scratching, chipping, peeling, fading and chemical attacks.

Application

Spandrel glass can be installed monolithically, using insulated metal backpans, but is more often found as a component of an insulating glass unit. Reflective spandrel glass units are widely used when a uniform all-glass look is desired for the building exterior. Typical applications include commercial fixed windows, curtain walls, storefronts and wall cladding. Spandrel glass is traditionally an opaque material not intended for use in vision areas.

Vitreous Enamel Frit

Vitreous enamel frit frit is a traditional coating that has been used for generations, but remains a tough modern finish.

It has impressive qualities of resistance to physical damage, heat, corrosion, ultra-violet light and yet it is compatible with many metal substrates.

It is suited to the demands of hundreds of products and capable of being decorated by several processes.

We can supply vitreous enamel frit either as frit, or ground into powder, as individual frits or blended for specific uses.

These products are for professional application, and need a heat source in the region of 800’C to fuse the enamel frit onto the metal substrate.

Requirements for Enamel Frits

An enamel frit must soften and adhere to the substrate without damaging it. This requires a relatively low softening temperature, typically ranging from 1,050-1,500°F (565-815°C). A decorated ceramic object might fire at 1,500°F, while thin-stemmed glasses might deform at 1,100°F. Clearly the same frit will not work equally well in both cases.

Once softened, the frit particles should flow together to eliminate porosity and form a coherent glass layer. In addition to the softening temperature, this overall firing behavior is related to the viscosity and surface tension, both of which vary with temperature. The glass frit should not soften too much before the organic medium is burned away, or combustion gases or partially burned medium can damage or become trapped in the glass layer. Escaping gases can disrupt the decoration and its bond to the substrate, causing pinholes or flaking. Carbon or bubbles trapped in the glass can result in unwanted light scattering or discoloration that will alter the color and gloss. Optimal appearance requires first removing the volatile medium and then allowing the frit to soften and flow sufficiently to obtain a coherent, pore- and defect-free glass layer with a smooth surface.

The enamel frit and substrate must be thermally compatible, meaning that once they are bonded during firing and start to cool down, their TEC must match sufficiently to avoid excessive stresses, or the decoration could crack or peel; the substrate could even fracture. Pigment type and amount can influence the enamel frit TEC, but the glass frit plays the dominant role. Most enamels have a slightly higher TEC than the substrate, so that on cooling a residual tension and compression exists in the enamel frit and the substrate, respectively. Type I borosilicate glass TEC is around 3.3 x 10-6/°C, while a soda lime silica container TEC is about 9.0 x 10-6/°C, so the same frit is unlikely to work well for both substrates. Ceramic products from different manufacturers can have significantly different TEC values. This can lead to quality issues when decorating blended lots from multiple sources, so it is recommended to run compatibility tests whenever possible when lots or sources are changed.

Decorating enamels are often used because of their mechanical and chemical durability, properties largely dependent on these same characteristics for the glass frit. Within a glass family, hardness and chemical durability generally decrease as the softening temperature is decreased. The common desire to lower firing temperature or reduce firing time pushes decorators to use lower temperature enamels or to slightly under-fire their current enamel frit. Either approach can reduce the mechanical and chemical durability. This can happen if the decoration and substrate are poorly matched, particularly if cracks are present. Cracks or poorly bonded areas increase the probability of damage from chemical attack or mechanical stresses.

Note that “chemical durability” is a somewhat generic term, and that durability for a decoration can vary widely under different conditions (e.g., acids, bases, temperature cycles, etc.). Standard testing methods, where samples have been generated under conditions simulating production firing, are recommended in order to make relative comparisons between candidate enamels.
