Is it good to contact the sealant in the car for many years?

It's definitely not good, although this thing doesn't hurt much, but it's definitely harmful to the ** if you have been exposed to a lot of it!

Green onion roast pork strips recipe.

The scallion roast pork strips can be cooled and heated, and the recipe name: scallion roast pork strips.

Cuisine: Home cooking.

Method: burned.

Taste: salty and fresh.

Type of dish: Hot dish.

Method: Raw materials.

300 grams of lean pork, 200 grams of white green onions.

Seasoning. 1000 grams of oil, Shao wine, soy sauce, sugar, vinegar, refined salt, monosodium glutamate, minced ginger, garlic slices, and an appropriate amount of starch.

1. Cut the meat into strips of 1 cm square and 4 cm long, add refined salt, monosodium glutamate, and Shao wine to taste, hang "gouache paste", fry it thoroughly in seventy percent hot oil, and pour it into a colander when it is golden brown; Green onions are white.

Wash, first cut in length, then cut into centimeter-long pieces for later use.

2. Heat the wok on the fire, add the bottom oil, add the green onion, minced ginger and garlic slices to stir-fry the fragrance, cook the wine, vinegar, add soy sauce, sugar, monosodium glutamate, add a little soup, and then add the fried meat strips, burn until the flavor is incorporated, thicken with water starch, drizzle the oil, and put it on the plate.

No, the spark plug is in contact with the high temperature of the combustion chamber, gluing will cause a fire, do not glue, the design of the spark plug has taken into account the problem of sealing, no need to glue. Remember.

We have the impression that the body of the car is made of steel plates, but we will find traces of sealant in many places on the body of the car, such as the door edge, the engine cover edge, the inside of the engine compartment, and so on. Why do these places need to be glued? Could it be that these parts of the body are glued together?

Of course not, there is a saying about gluing here, mainly to play the role of sealing, rust prevention and decoration.

The car body is stamped into parts with steel plates, and then assembled together and welded to finally assemble the entire body. For example, the car door, which looks thick, is actually empty in the middle, and is made of two layers of door panels spliced together and welded together.

And this welding method is not our common full welding from head to tail, but spot welding, with a solder joint at a certain distance. The picture above is a schematic diagram of spot welding.

Spot welding will inevitably cause gaps in the splicing joints except for the solder joints. If these gaps are not treated, they will first affect the aesthetics, and secondly, dust, water vapor, and even rain will enter the car through the gaps during the use of the car. Over time, it will cause the body to rust from the inside out.

Since this rust first occurs inside the car body, it is difficult to detect the problem in the first place, often when it is completely rusted from the inside to the outside, and by this time it is already too late.

Because the welds have the risk of water ingress and are extremely unsightly, these welds are sealed with sealant in the production of automobiles to prevent water vapor from entering and causing rust.

Body seals are divided into coarse seals and fine seals, coarse seals are mainly used in chassis, engine compartment, trunk and other enclosed spaces, these places are generally not seen, so coarse seals have relatively low requirements for aesthetics, only for tight sealing, good looks are secondary. Therefore, we will find that the sealants in the engine compartment, chassis and other parts of many cars are particularly arbitrary.

The fine seal is mainly used in the door, wheel cover, engine cover, trunk cover and other obvious parts, these places are easy for us to see, so the fine seal in addition to the requirements of sealing, but also for aesthetics. So the sealant on the doors is very even and smooth.

Now you know why the body needs to be glued.

1. Check whether the sealing strip has large cracks and breaks. If the sealing strip is broken, it can be repaired with adhesive. Especially to use.

The special adhesive for the sealing strip can easily repair the large crack strip. Of course, if the seal is severely damaged, or the degree of aging is large, it is best to replace the seal with a new one.

2. After the owner uses car detergent to clean the door and window sealant, it is best to coat a layer of high permeability protector, which can not only prevent the aging of the sealing strip but also greatly improve the sealing of the sealing strip. On top of that, the gaps in the sealing strip can easily be stuffed with sand and dust, which can cause rust. To do this, use a brush to remove sand and dust.

3. When replacing the whole car body, a layer of sealant should be applied to the lap part of the weld, and the thickness of the adhesive layer should be about 1mm, and the adhesive layer should not have defects such as false stickiness and bubbles. The entire lower surface of the floor and the lower surface of the front wheel cover should be coated with 3mm-4mm elastic coating and anti-corrosion coating. These measures can not only greatly enhance the sealing of the whole vehicle and slow down the corrosion rate of the body, but also greatly improve the ride comfort.

4. The sealing of the door and the body is a more difficult part, the sealing requirements are stricter, the part that should be sealed is relatively long, the cross-sectional shape of each sealing part is not the same, and the door opens and closes frequently. In luxury cars, it is common to install 3 or 4 seals, and install a quadruple seal structure for the front pillar and roof side cross member. This kind of multi-channel sealing is generally arranged in the front door crack, in addition to having the sealing function, it also has the effect of car sound insulation and noise reduction.

5. After the window glass is damaged, the owner should check whether the sealing strip is damaged when replacing the glass. Since the windows often do not return to their original shape after repair, it is necessary to pay attention to the tightness around the window glass in addition to ensuring that the window glass can be easily pulled or lifted. If the gap between the glass and the glass notch is uneven, and the rubber strip is in poor contact with the glass and the glass groove, the owner can easily pull off the sealing strip by hand.

6. When changing the roof, the owner should first apply a layer of conductive sealant at the pressing place around the roof, and then apply the hemming glue in the flow tank and the seams after welding, which not only helps to seal the body, but also prevents the body from early rust due to water accumulation at the flanging weld.

7. The car sunroof is the basic configuration of most family cars. When the sunroof is opened, the rubber sealing track is exposed to the air, which inevitably accumulates dust and even runs into small gravel. Prolonged use may cause the sunroof to deform due to wear and tear and clog the drain holes.

Therefore, it is important to clean the tracks regularly and apply lubricating oil to the tracks.

Although the automotive sealing strip is a small part in the body, it can ensure that the opening and closing of the door sinking foundation is stable and heavy, and can also make the car shelter from weather, dust, heat and sound insulation, and play a decorative effect on the edge of the door and window handover. When the body is vibrated and twisted, the sealing strip also plays the role of cushioning, shock absorption and protective glass. Therefore, car maintenance is no trivial matter, and no link can be ignored.
