It's basically 1 to change the wiper in the store, 200 yuan. On the internet, you are worried that the wiper you choose is not clean or of poor quality. 1 and 2 months will creak there. How to choose? I checked five papers for you, and combined with the actual measurement, I will explain them to you.

Whether the wiper works well depends on the material: the scraping effect depends on the resilience of the steel sheet.

First of all, it depends on the material of the rain, which directly affects the use effect of the wiper. If you look at it, it is relatively simple, mainly looking at two places.

1 This number is the scraping effect, and the focus is on the resilience of the steel sheet.

Steel plates with poor resilience are easy to straighten after 1 or 2 months. After the wiper strip is straightened, it can't get enough downward pressure, and it can't fit the windshield well, so it is easy to appear banded waterline when it is used.

Therefore, it is necessary to choose a wiper steel plate with good elasticity.

But companies will say that they are flexible. What do we think? What ingredients are usually used?

Write down a word-high carbon steel, which has a higher elastic limit than ordinary steel plate, is better, is not easy to deform and is cleaner to scrape.

See rubber strip coating for durability and low noise effect.

Second, if you want the wiper to be durable and quiet, the key point is to look at the coating of the adhesive tape. Don't think it's rubber, it's covered with something.

If the car is parked outdoors and exposed to the sun for a long time, it will lead to the aging of the rubber strip, resulting in deformation or stiffness and loss of elasticity.

It is easy to scratch when using, and it will make a "giggle" sound or a "squeak" sound.

Therefore, the surface of wiper strip is usually coated with 1 to protect the rubber strip and increase the effect.

There are good and bad paints. When choosing, click on the details page or ask their customer service directly. You asked him what kind of composition and coating he used.

I checked the information for my friend. There are three common coatings: molybdenum disulfide, graphite and polytetrafluoroethylene.

This is great. Sometimes the price with good effect is not so expensive, but the price with average effect is quite high, which may be related to the brand.

Teflon with better effect has better weather resistance, corrosion resistance and lubrication performance, which is stronger than the other two, and cars in the middle and high-end market are also used more.

This is also easy to understand. Is there a big difference between the experience of ordinary pots and non-stick pots?

And coincidentally, the non-stick pan coating is called Teflon, and our wiper is also called Teflon. You can think about the high temperature resistance and its smoothness, and the gap is still quite large.

Depend, see if the rain has done quality inspection.

Of course, it is not enough to look at the material, but also to see whether the rain scraping has done quality inspection. Because if the material is good and the quality control is not good, it may not be easy to use.

Therefore, wiper production has industry standards. QC/T 44-2009 "Electric Wiper for Automobile Windshield" stipulates the technical requirements for rain scraping, which can be compared.

For example, the scraping effect requires the scraper to scrape the place 500,000 times to clean it, and the width below 0.5 mm can only have three scratches at most. ..

Just like the checked wiper, you also bought a peace of mind and peace of mind.

Also pay attention to the matching of wiper size and model.

Finally, there is another place to pay attention to: the size of the wiper should match its own model. Different models of interfaces may be different. The interface says "I am right about everything", and the radian is different. The size after installation depends on it.

Therefore, when choosing a wiper, you should choose the appropriate model according to your own model. Wrong choice, no matter how good the materials are.

Friends who don't know how to choose, or find it troublesome to choose, can also have a look at this boneless wiper I chose for my friends. From materials to quality control, it is also carefully selected according to the standards of previous content. The coating is Teflon, and the steel sheet is high carbon steel, which is also a good SK5 high carbon steel. The small details of the wiper interface have also been upgraded. If you search online, it's usually plastic. Ours is made of metal, which will be more firmly stuck, more stable to use, more reliable at high speed and of course more durable.
