How to Understand It’s Time to Consider Auto Glass Replacement

Repair or replacement: when the car windshield becomes dangerous. Traffic rules do not strictly regulate the condition of the windshield, only prohibiting the operation of the car without it. But it doesn’t mean you should forget about the timely repair or auto glass replacement: they directly affect the inspection and hence the welfare of the driver and his passengers. But sometimes, a chip or a small crack in the windscreen makes you think whether to change it or better wait. Suddenly, another stone will fly from under the wheels tomorrow. So how do understand that it’s time to solve the problem by going to the service station, and dismissing all doubts.

For some reason, many motorists do not care about the condition of the windshield. Some manage to drive even when it is impossible to see the road behind a network of cracks. These are, of course, extreme cases, but they do occur. The conclusion in such situations is simple – the glass may fall at the wrong time on the driver’s knees.

No options

Triplex, consisting of three layers, holds fragments, making the glass safe, for example, when hit by stones (there is a special strong film between two layers of glass).

It is impossible to repair such a triplex, thus, the only replacement will save the situation. And to bring the part to a critical state is dangerous: if, during the day, it is still possible to see something through the network of cracks, then in the dark, you have to go almost blindly. Not only the lack of normal lighting but also the brightness of headlights that will repeatedly refract. In this case, the only right choice is auto glass replacement.

To be or not to be

But some defects really put before the choice: to repair or replace with a new one. Unfortunately, there is no consensus here. Experts in different companies give conflicting recommendations. The most careful recommendations are the repair of small chips up to 1 cm in diameter without cracks no longer than 5 cm.

Braver specialists are ready to restore the windshield with any chip or crack that does not occupy more than half the width or height of the glass. Listening to the latter is a risky business, threatening not only the money wasted for repairs but also an emergency situation if the next stone “finishes” the glass, which has already lost its strength.

But most agree that it is definitely not worth repairing the glass again. In addition, you will have to spend on a new windshield if the crack has reached the edge of the crack in the area where the “wipers” work, on the side where the driver is sitting.

Age makes its own adjustments

And here is another situation where the owner must replace the windshield. And in these cases, no repairs, restorations or restorations are provided. We are talking about natural wear and tear. On average, the windshield can withstand from 80,000 to 130,000 km if, of course, you have managed to save it from the notorious stones.

What happens to glass over time? It gets micro-cracks and scratches and loses strength and other quality characteristics. In addition, “tired” glass scatters light. But it is better not to resort to polishing: the surface is almost impossible to align, thus, auto glass replacement is on time.

Methanol To Olefin Technology

Indonesia is a country that has never been talked about in the eyes of the world. The blue of the ocean and the natural resources of this country seem to be a pearl for those who see it. For almost 75 years this country has been independent of the right to power for its homeland, with a population that is now above average, of course, forcing the government to rack its brain to manage its natural resources.

It is recorded that there are 267 million people living in the paradise land of Indonesia. Of course, with a population capacity that is quite extraordinary, some data and facts will emerge which will result in the explosion of the growth rate in Indonesia. This time the red and white country was seriously affected by the increase in population. One of the sectors affected by the demographic bonus that hit besides oil energy as a resource that is quite vital is the petrochemical industry.

In the last few decades, Indonesia has experienced an energy deficit, one of which is caused by the high demand and import of raw materials for the petrochemical industry. It should be noted that the petrochemical industry is also one of the industries that is quite vital in ensuring the survival of the Indonesian people.

What is the petrochemical industry?

Petrochemical is an industry that operates in the processing of chemicals by using raw materials from the results of the processing of oil and natural gas. Indirectly the petrochemical industry is also related to the oil and gas industry or often called oil and gas. Of course, this is something that is quite difficult for the petrochemical industry to maintain the continuity of the process

Briefly, petrochemicals are divided into three, namely upstream, intermediate, and downstream. For upstream petrochemicals, examples of semi-finished products are propylene, benzene, toluene, ethylene, methanol and so on. In petrochemical intermediates, products such as polyethylene, ammonia, butene, dichloroethylene-vinyl chloride and so on are obtained. While downstream petrochemicals produce finished goods that we often encounter such as fertilizers, clothing fibers, cosmetic tools and so on.

Well, to produce all the types of products above, of course the petrochemical industry must rack its brains to get raw materials that are easy to get and economical. In general, there are 3 classifications of raw materials for the petrochemical industry, namely olefins, aromatics, and natural gas synthesis.

What are the most common problems?

We need to know that to produce the petrochemical products above, of course, we need hydrocarbon raw materials, such as ethane, naphtha, and coal gas. One of the current sources of weakness in the national petrochemical industry is the limited number of hydrocarbon raw materials.

The world currently has two main raw materials for the petrochemical industry, namely ethane gas which is mostly used in the United States and the Middle East. Meanwhile, naphtha is used as a raw material in Asia Pacific and Europe. One of them is Indonesia, which currently uses naphtha, especially at Chandra Asri Petrochemicals (CAP).

One of the strategies to strengthen the petrochemical industry, Indonesia needs to secure the supply of natural gas, naphtha, and coal with a clear and structured roadmap, since the price of petrochemical products is highly dependent on the price of raw materials.

The contribution of raw materials in the final price can reach 70-80%. Of course, the selection of raw materials is very important. In general, natural gas-based industries have better profit margins than naphtha although the product spectrum in naphtha-based petrochemicals is more varied.

Coal is also a strategic raw material for Indonesia. With the current oversupply of natural gas in the world, coal prices will remain low. For this reason, some of the coal needs to be processed domestically to produce petrochemicals. With the right pollution mitigation technology, pollution in coal-based industries can be minimized. ( Muraza, 2020 )

Therefore, it is necessary to apply Methanol To Olefin technology massively in the motherland to continue to strengthen the petrochemical industry in Indonesia. Because we know that olefins are the biggest need in the production process in the petrochemical industry.

Getting to Know Mehanol To Olefin Technology

The Methanol to Hydrocarbon process was discovered in Mobil Oil in 1977. This process is used to convert methanol into products such as olefins and gasoline. The first methanol can be obtained from coal or natural gas. In the Methanol to Olefin (MTO) process, methanol is then converted to olefins such as ethylene and propylene. Olefins can be reacted to produce polyolefins, which are used to make many plastic materials. Honeywell’s advertised MTO process flow chart is shown below.

Of great importance to the successful application of the MTO process is the acid zeolite catalyst. Without this catalyst, the chemical reactions involved in the MTO process would be too slow for the process to be economically feasible. (Wang et al. 2006). In short, it may be concluded that the essence of Methanol to Olefin is the process of making olefins from natural gas, coal.

Therefore, in my opinion, it is quite important for the Methanol To Olefin process technology to be applied massively in Indonesia, considering that Indonesia has abundant natural gas sources of coal.
