So it is necessary to change the anti -freezing glass water to the car

But many car owners don’t know how to choose

So I bought 8 anti -frozen glass water of different brands

I hope to pass the following 4 tests

Help everyone choose a cheap and practical glass water

8 product information tables for this test:

One, unit price,

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

The unit price mentioned here is the unit price per liter.

Because glass water is greater than its own cost.

So theoretically, the more you buy, the cheaper the unit price of each liter.

It can be seen that the most expensive and cheapest is nearly 10 times the difference.

Second, corrosive;

The corrosiveness mentioned here refers to the corrosion of glass water for wiper adhesive.

Because frozen glass water is added with industrial alcohol methanol, ethylene glycol, one yuan alcohol, and propylene glycol.

These raw materials can corrode the wiper adhesive bar and plastic, causing the wiper glue strip to quickly aging and reduce the service life.

Of course, their corrosiveness is also different. Better raw materials can minimize corrosive rubber strips and plastic under the premise of ensuring anti -freezing.

So I specially prepared an old wiper adhesive and a brand new wiper adhesive.

I cut the two rubber strips into 8 sections, and then measured the initial length of each new and old rubber strips with a cashmere caliper.

They are divided into 8 groups, each of which has a new glue bar and an old rubber strip, and then the 8 groups of rubber strips are soaked in the test tube equipped with 8 different glass water for a week.

After a week, let’s see if the length of these 8 groups of rubber strips will change, so that these antifreeze glass water will affect the corrosion of the rubber strip.

A week later …

I took out all the adhesive strips from glass water, and then measured the length of all rubber strips with a gigarette calibration.

Then use the measurement length to minimize the difference obtained by the initial length, and then remove the expansion ratio of these adhesive bars with the initial length.

Then you can see the effects of 8 kinds of glass water on the rubber strip through the expansion ratio.

I won’t go into details one by one.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

Through the data above, you can obviously look at these new old wiper adhesives. After soaking in antifreeze glass water for a week, it has obviously become longer.

The smallest impact of corrosion is Bai Shitong and turtle cards, and the expansion rate of new and old rubber strips is between 0.3%and 0.6%.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

Followed by 3M and CICIDO, the expansion rate of new glue in 3M is 1.3%, the old rubber strips are 0.47%, the expansion rate of new glue soaked in CICIDO is 1.6%, and the old rubber strips are 0.25%.

Then there is a blue star.

Then there are Tuhu and a Duoduo TOP1. The expansion rate of the new glue soaked in Tuhu is 1.25%, and the old rubber strips are 3.26%. The expansion rate of the new glue soaked in TOP1 is 1.09%, and the old rubber strips are 3.11%.

Finally, the expansion rate of the new glue soaked in TOP1 was 2.27%, and the old rubber strip was 3.22%.

in conclusion:

Just look at the effects of antifreeze glass water on the corrosion of the rubber strip.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

I personally think that these 8 glass water can be divided into 4 echelons.

One echelon: Bai Shitong, Turtle cards.

Second echelon: 3M, CICIDO.

Three echelons: Blue Star.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

Three echelons: Tiger, a lot of TOP1.

Fourth echelon: Top1 of a certain treasure.

Third, cleaning ability;

For this test, I specially prepared a pile of artificial “bird shit”, and completely cleaned the car windshield and wiper gum.

Then I first dripped a drop of artificial bird shit in front of the windshield and cleared the glass kettle to pour pure water.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

See how many back and forth on the wiper to scrape the glass to completely scrape this artificial bird shit.

The last test found that it needs to be scraped 15 times back and forth with pure water to scrape this drop of artificial bird feces.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

Then I officially started testing. Each test of glass water, I will empty the glass kettle first, completely clean the glass and wiper, and then drip the other amount of artificial bird shit on the glass.

The test process is boring and boring, that is, constantly pour glass water and clean the glass. I won’t go into details with everyone here.

3M

Scraped a total of 7 back and forth on the wiper

Baitong

A total of 8 times of wiper is scraped back and forth

Cicido

The wiper was scraped 41 back and forth, and did not completely scrape the artificial bird shit completely

I added glass water in the middle of the test …

Tiger

The wiper was scraped 39 back and forth, and the glass water was added in the middle of the test.

Turtle card

Scraped 8 back and forth wiper back and forth

A certain treasure TOP1

35 back and forth on the wiper

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

A Duoduo TOP1

28 wiper back and forth

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

As a big international brand, 3M, Bai Shitong, and Turtle Brand have exerted the clean ability that should be used.

The cleansing ability of domestic veteran blue star anti -frozen glass water is not exaggerated to compare with three big names.

As for CICIDO, Tuhu, TOP1, a Duoduo TOP1, to be honest, the cleaning ability can be scraped cleanly with 15 times …

Fourth, the real freezing point value;

I really bought two different freezing points detectors.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

One is specifically detected free -frozen glass water freezing point with ethylene glycol and propylene glycol, and the other is to detect glass water freezing points with methanol as raw materials.

Here I briefly talk about the reading method of the freezing point detector. The left side of the red box in the figure above is the number of propylene glycol -free frozen solution, and the number of antifreeze reads of the ethylene glycol type on the right.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

So I draw 8 different glass water in turn, drip on the corresponding freezing point detector, and then record the freezing point value.

1. 3M.

It is even lower than the target value, and it is still very good and there is no deficiency.

2. Bai Shitong.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

It is 13 ° C than the marking value. This is also unexpected, and I have repeatedly measured the calibration. It is still -50 ° C. It seems that the manufacturer is still very honest.

3. Blue star.

The main component of the blue star’s glass water ingredients is one yuan alcohol, but it is mainly used for glass water to make a methanol, which is actually methanol, so I use the freezing point detector of methanol to detect.

Its actual freezing point is also 17 ° C lower than the ingredients. I would like to call it a domestic conscience merchant.

4. CICIDO.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

The actual freezing point of measurement is 14 ° C than the freezing point marked, and there is no false standard.

5. Tiger.

The actual freezing point of the measurement is also 14 ° C lower than the ingredients, and there is no deficiency.

6. Some treasure top1.

Because this glass water bottle did not clearly write what the main raw material is.

So I can only drop glass water on two different freezing points detectors.

It was then found that the readings on the melterol freezing point detector were 0, while the readings on the methanol freezing point detector were -37 ° C.

Therefore, the actual freezing point of this glass water is also 12 ° C lower than the ingredients.

7. Turtle card.

Because this glass water bottle did not write clearly what the main raw material is.

So I can only drop the glass water on two different freezing points detectors.

It was then found that the readings on the melterol freezing point detector were also 0, while the readings on the methanol freezing point detector were -42 ° C.

Therefore, the actual freezing point of this glass water is also 17 ° C lower than the ingredients.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

8. Top1.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

This glass water does not write what raw materials are.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

So I can only drop the glass water on two different freezing points detectors.

However, the readings on the melterol freezing point detector are still 0, and the readings on the bell-like freezing point detector are -36 ° C.

The measured freezing point value is higher than 4 ° C.

Summarize:

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

3M anti -freezing glass water unit price is the most expensive, and some TOP1 is the cheapest.

Bai Shitong and turtle brand anti -frozen glass water has the least corrosive corrosion.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

A certain treasure TOP1 antifreeze glass water has the most corrosive corrosion.

3M, Bai Shitong, and Turtle -brand anti -freezing glass water cleansing ability is the best.

CICIDO and Tiger’s anti -freezing glass water cleansing capacity is the worst.

Bai Shi Tong -anti -freezing glass water is the lowest in the measuring freezing point, followed by blue star anti -freezing glass water.

价格相差10倍的防冻玻璃水,区别在哪?师兄实测给你看

I believe that you just take a closer look at the picture.

It is easy to find antifreeze glass water suitable for your own car.

Finally, remind everyone!

Do not mix with any different brands of non -freezing glass water at different freezing points!

Because after I finished the cleaning ability of 8 types of anti -freezing glass water, I found that the glass spraying mouth was blocked …

After replacing two new water -spraying aites, the water spray pipe was still blocked, and I had to re -clear the entire glass water pipe.

So remember to keep this!

The above is the evaluation of 8 anti -frozen glass water this time.

I hope to help you, when buying anti -frozen glass water.
