How to use foam caulking tip without tip_Toluene diisocyanate manufacturer

Foam caulkIt is very common in our daily life. It is also called foaming glue and foaming agent. It is aWith foaming properties and bonding propertiesPolyurethane adhesive, which is mainly used for building doors and windows Filling, sealing and bonding of joints, component expansion joints and holes. Then Foam caulk without gun tipHow to use it?

一 . How to use foam caulking agent without a gun tip?

1, ready Foam gun andfoam caulk, willFoam caulkShake it vigorously a few times in the transverse direction of the can body to fully mix the prepolymer in the tube. Remove the valve protective leather cover on the threaded ring of the foaming agent, remove the cleaning agent from the foaming gun, and Foam caulkThe can body is connected to the interface of the foaming gun.

2, hold the foam gun tightly Use the handle to open the flow regulating valve of the foam gun, aim the gun head at the bottom or inside of the part to be filled, gently pull the trigger, and start construction. After each tank of construction is completed, a special cleaning agent must be used to clean the threaded part of the glue gun. After each continuous construction, a special cleaning agent must be used to clean the entire glue gun barrel to avoid solidification and blockage.

2. Foam caulkHow<font face=" What to clean?

1, Rinse with clean water. Wash with plenty of water while it is not cured. The uncured foam is harmful to the skin and Clothes are highly sticky, and acetone is toxic and classified as a hazardous chemical. It is not recommended for non-professionals to use it.

2, Cleaning agent. Using specialized cleaning agents on the market, conventional water washing methods cannot clean If it falls off, you must use professional cleaning agents to wash it off. There are special cleaning agents in the building materials market<font face= Cleaning agent for foam caulking.

3, try acetone to clean font>. Acetone and Foam caulkThey are all organic substances with the same polarity. According to the principle of similar miscibility, the effect can be achieved. Some people say that gasoline is also feasible. The principle is the same. It might as wellyesTry it.

4, remove with a blade. etc.Foam caulkAfter it dries, use a razor blade to cut or scrape off the removable parts. If it is stained on clothes, put the clothes in the sun for a few days, then rub it with your hands after a few days. Foam caulkwill slowly change color and turn pink under strong ultraviolet radiation. But foam caulkwill still leave stains on clothing. Foam glue stuck to clothes can be cleaned with toothpaste. The foam glue remaining on the door can be washed with boiling water.

5, use a hair dryer to blow it to make it sticky The glue softens, making its adhesion weaker and easier to remove. If there are still any small marks, wipe it off with nail polish remover.

三 , What is the difference between foaming agent and foam glue?

1, from the concept Technically speaking, the foaming agent is just a simple additive that can react with other substances to promote decomposition, and can also achieve the curing process to form a good sealing effect. Foam glue is an adhesive product with good performance. It has good adhesion, high elasticity and good stability. It can better achieve gap filling and sealing and ensure the efficiency of industrial production.

2. In principle, two Both can be cured to form foam, but foam rubber decomposes faster. When in use, as long as the material is sprayed out of the gas tank, it will quickly come into contact with the heavy moisture in the air to form foam. The foaming agent requires a certain material reaction to form foam.

3. The two are also different in terms of use. After the foaming agent forms foam and solidifies, it is generally used for automotive lamp sealing and electronic precision parts gluing. Pick up and wait. Foam rubber is mostly used for waterproof sealing of switches, lithium batteries, auto parts and other products.
