Glue overview: glue is an intermediate connecting two materials, mostly in the form of water agent, belongs to fine chemicals, there are many types, mainly in the form of adhesive, physical form, hardening method and the classification method of the material to be adhered to. Common ones include instantaneous adhesive (common 502-cyanoethyl acrylate strong instantaneous adhesive is a kind of adhesive), epoxy resin bonding, anaerobic adhesive, UV glue (ultraviolet light curing), hot melt adhesive, pressure-sensitive adhesive, latex, etc.
So you won't get sick.

Working in a tannery for a long time, it is naturally easy to get sick, and you can ask the unit to have a regular physical examination for you to prevent occupational diseases.
-
See a doctor. If you don't do it, it will develop into an occupational disease. There is an opportunity to have an occupational disease assessment to file for workers' compensation.

Most glues contain CH2O formaldehyde, which is the culprit of carcinogenesis and leukemia! Go to the hospital for a check-up, don't delay!
-
To see whether the glue is environmentally friendly, it is recommended that you may not use solvent-based glue, because the solvent has a low melting point and fast volatilization, all in your operating space, and finally you will be inhaled into the body if the ventilation of the plant is not good.
-
It seems that it is poisoned by benzene solvents, formaldehyde, etc., now change jobs! Health is always a must!
-
Why does the landlord first think of the local method instead of the hospital? Could it be that the current hospital has reached a point where people dare not think about it? Alas, even this is the place where the hospital should go.
-
Let's go to the hospital and check it out. Specific conditions. We hope you will go to the hospital as soon as possible. May you be healthy.

Different glues have different solvent ratios. Such as New Oriental glue PU-1975, the solid content is 75% and its ratio is: main agent:
Curing agent: ethyl ester = 5:1:
9 is 20:4:36 working concentration 30%.
When the temperature of the workshop is high and the humidity is high, the curing dose is generally increased by 5% and 10%.
Composite glue 1:1 ratio.
-
Leather lamination is now generally made with hot melt adhesive films.
Compared with glue, hot melt adhesive film has the following advantages:
Environmentally friendly and harmless; Reduction of overall costs;
High efficiency; Cleaner production, no dripping;
-
Leather composite depends on what products are produced, if it is PU leather and sponge, PVC leather and cloth can try water-based glue composite, Hebei, Henan many car seat composite factories, are used Tianxinda water-based composite glue, no smell, there is a guarantee for workers. The adhesion is good, the composite leather is elastic and not hard, and the composite area is also a lot, you can try it.
-
Adhesive leather can be used transparent slow-drying semi-flowing glue Toughness after curing HY-P121 viscose leather Instant adhesive can be used for a small area Easy to apply sizing and fast curing HY-308 is a good choice.
-
Absolutely harmful, but the content of harmful substances is within the scope of the national standard, and the harm is negligible.

This one is easy to identify. If you go to the regular Beijing cloth shoes counter, there will never be a glue smell.
If you go to a general imitation Beijing cloth shoe store, most of the shoes have a disgusting glue smell.
Or maybe it's the difference between a sneaker store at a counter and a "smuggled smuggled shoe" sold on the street.
But no matter what, there are a lot of differences. Among them, there are obvious differences in workmanship, quality, and processing methods.
The difference between domestic shoes and foreign goods is mainly manifested in the technical treatment of finished shoes, but any shoes are made of rubber, leather, cloth and some chemicals, and it is inevitable that there will be taste problems. But the inferior materials and workshop-level manufacturers make the products taste disgusting!

Method 1: 1. Let the boots air dry, preferably outside the house to receive direct sunlight. The laces should be unfastened, the insoles should be removed, the boots should be opened to the maximum, and the newspaper should be tucked into the shoes to absorb the moisture.
2. Never bring wet boots near a heat source, such as a fire or heater. Otherwise, the leather will shrink and your shoes will be half a size or the leather will crack. The rubber sole will melt.
3. Use a nylon shoe brush to brush off the dust. For stubborn stains and salt, rinse with clean water before brushing off with a brush.
4. Use an old toothbrush to brush the dirt in the hidden places and crevices.
5. Put baking soda into your boots to remove moisture and glue smell.
6. If the skin looks dry and starts to lose its color, you should moisten it as soon as possible to prevent it from cracking. Consult the manufacturer of the shoe and use the method he recommends.
7. Use chrome steel to remove rust on the metal.
8. Once your boots are washed as good as new, keep them in a cool, dry, dark place for next use.
Method 2: You take a mothball, wrap it in paper or film, be careful not to wrap it too tightly, so that the smell inside can evaporate! Putting it in your boots works great to repel the smell of glue!
By the way: be sure to buy real mothballs, the market price is yuan, the effect is very good!

The newer the shoes, the stronger the glue smell.
New shoes such as Nike Adidas have a glue smell, and *** glue also smells This is inevitable unless the smell is manually dispersed before the new shoes are put on the shelves, of course, the smell is still light and heavy, and it is generally acceptable.
If the taste is strong and pungent and does not weaken for a few days, it is a quality problem.
-
This is normal, glue and glue are not the same, and a good shoe is hand-sewn, many inferior shoes are directly glued with glue, and the quality must be poor!
