What is the difference between structural adhesive and glass adhesive? What kind of glue should be u

Glass glue is a common name! We all call silicone sealants divided into neutral and acidic, then divided into weather-resistant and structural adhesives, neutral into alcohol type and ketone oxime type. It is better to stain the mirror with alcohol, and it will not spent!

There are more ketone oxime types on the market, because they are relatively cheaper than alcohol types! Structural adhesive is used for structural purposes, generally played internally, connected with other substances, the tensile force is larger, the displacement is smaller, the weathering adhesive is also bonding and weather-resistant, the displacement is larger, the glue fatigue is cheap! It is recommended to use weather-resistant glue for the bonding of the mirror and the wood, thinking that the wood will shrink, and the displacement of the structural glue will be small, and the mirror will be broken!

It is necessary to use alcohol-type weathering glue, neutral acidic will corrode the mercury and spend the mirror! Remember to buy a good glue! Can be glued directly!

But know that the silicone glue dries slowly, and it takes a week to dry completely!

It is divided into neutral and acidic. It is better to stain the mirror with glass glue and not to spend!

Structural adhesive refers to an adhesive with high strength, can withstand large loads, and is resistant to aging, fatigue and corrosion, and has stable performance in the expected life, and is suitable for bonding structural parts with strong strength.

The structural adhesive has high strength, peel resistance, impact resistance, and simple construction technology. It is used for bonding between metal, ceramic, plastic, rubber, wood and other materials of the same or different materials. It can partially replace traditional connection forms such as welding, riveting, bolting, etc.

The stress distribution of the joint surface is uniform, and there is no thermal influence and deformation on the part.

Glass glue is a commonly used adhesive in the family, the main ingredient is sodium silicate, soluble in water, viscous, also known as water glass in the south, and bubble alkali in the north. It is a material that bonds and seals various types of glass with other substrates.

There are two main categories of glass glue: silicone glue and polyurethane glue. Silicone glue is divided into acid glue and neutral glue, neutral glue has structural glue and sealant and weather-resistant glue. Polyurethane adhesives are divided into adhesives and sealants.

Most of the glass adhesives sold on the market now also have functions such as mildew prevention and weather resistance, and consumers should choose according to their actual needs. Generally speaking, the washbasin and toilet in the bathroom, and the countertop in the kitchen should be made of glass glue with anti-mildew performance, which can be acidic or neutral; Metal ceilings, shower rooms, and mirrors should be made of mildew-proof neutral glass glue, rather than acidic ones.

The word glass glue is too broad. Generally, structural adhesives and polysulfide adhesives are used for architectural glass. Structural adhesive is mainly used in glass curtain walls, and polysulfide adhesive is generally used in glass doors and windows.

As for the mirror to be bonded to the wooden board, if the board surface is not large, it would be good to use it as the glue of the fish tank. **Very cheap, generally around 8 yuan.

Glass glue is also OK, but you have to buy ***, generally buy about 10 yuan.

The advantages of structural plus are also very obvious, the adhesion is relatively high, and it can resist peeling and impact. Structural adhesives can be used to bond many items, such as metals, ceramics, plastics and rubber, and there is a certain substitution, such as sometimes replacing welding. Glass glue can also be divided into two properties, one is high-performance, the other is medium-performance, generally high-performance will be used in building materials, in the glue does not need any instrument to directly produce adhesion, and can be extruded at any time, but also anti-aging.

However, neutral structural adhesives also have good adhesion for more temperature requirements.

The degree of adhesion is not good, the viscosity is different, the use is different, the color is different, the classification is different, and the firmness is different. It is definitely the structural adhesive that is more effective, because the structural adhesive can be used to attach any substance. Glass glue can only be used to stick some glass or window frame seals.

The quality is different, the material of the glue is different, the effect of the glue is different, the adhesive strength is different, and the way of use is different. It must be that the structural adhesive is a little more effective and more sticky.

Structural adhesives are used for building exterior walls, glass roofs, sun protection, weather resistance, and good waterproofing. Glass glue is used in indoor washbasins, washbasins, vegetable sinks, toilets, etc. Stronger structural adhesiveness.

The structure is firmly glued.

The adhesion of structural adhesive and glass adhesive is different, glass adhesive is a kind of sealant, its sealing performance is very good, but the adhesion is far less than that of structural adhesive. Structural adhesives have high requirements for adhesion, and its adhesion is mainly manifested in compressive strength, tensile strength and shear strength. The compressive strength of the structural adhesive can reach 65MPa, which is equivalent to 630 kg.

Precautions for the use of structural adhesives.

1. Silicone structural adhesive should be used under clean environmental conditions with a temperature of 5 -405 and a relative temperature of 40%-80%r, so as to obtain a better bonding effect.

2. Temporary protective tape should be pasted on the vicinity of the surface of the cleaned substrate to be bonded, and the primer should be applied before sizing.

3. The one-component structural adhesive can be directly extruded from the plastic tube or sausage type packaging by manual or pneumatic colloid, and the two-component structural adhesive must be applied using special sizing mixing equipment.
