All of us should know that building construction is now a major project in the society. Because people themselves or the needs of society, many empty lands are now built into buildings. I believe we all know more or less about building construction. A lot of materials will be used, one of which is adhesive steel. As its name implies, it is used to fix some steel structures. However, some details on the adhesive steel formula may not be known to us. Now I will give you a detailed explanation of the adhesive steel formulation and related knowledge.
Sticky steel features
Sticky steel adhesives are often used for the bonding, reinforcement, and repair of some hardened structural parts in the field of construction engineering. Sticky steel adhesive features strong viscosity, good acid and alkali resistance, anti-aging, anti-fatigue performance, strong impact resistance, non-toxic, non-volatile, long life, easy to use, convenient, stable performance.
Steel glue dosage
Adhesive steel glue usage design specifications are: 3mm~5mm.
Steel adhesive formula
The main technical performance indicators of adhesive steel:
Component: A and B two-component
Temperature resistance (°C/Mpa): 80/18
Colloidal self strength (Mpa): 70
Density after mixing (g/cm) 1.4-1.6
Recommended ratio (weight ratio): A: B = 2:1
Elastic modulus: 1.2x10
Operating temperature (°C): -5-40
Steel bond strength (Mpa): Shear 22
Operation time (min): 20-40.
Process flow:
Surface treatment of concrete and steel plates → Preparation of colloids → Adhesion → Pressurization → Surface treatment of steel plates.
Formulation processing:
Now mix the A and B components of the building structure glue and mix them together according to the proportion of Group A:Part B=2:1 (by weight).
With plastic note:
(1) When the temperature is low, the components A and B should be warmed in a 60-80°C warm water pot to reduce the viscosity.
(2) Parts A and B should be obtained separately from the container. Take 2 parts of the first component and put it into the prepared container. Then take 1 part of the B component and put it into it. Stir it evenly.
Stick steel:
The adhesive surface of the bonded steel plate is handled cleanly, and the adhesive is evenly coated in a dry environment, and the adhesive is contacted, pressed, and fixed.
Curing:
This product is suitable for use in construction environments below 60°C, and the initial setting time is 1.5 hours at room temperature. It is completely cured at room temperature one day, and can also be cured under negative temperature and humidity conditions, and the curing time is appropriately extended.
Adhesive steel adhesive application scope
1. Reinforcement of the external member of the concrete member in the transformation project.
2. Self-adhesion and mutual adhesion of various building materials in civil engineering.
Stick steel price
The price of adhesive steel is mainly related to the different brands, models, and sizes of packaging specifications. In addition, the difference in the seller, time, and purchase amount of adhesive steel can also affect its specific price. Loctite e-120hp adhesive steel 50ml price 50 yuan; gold gun 3608PP adhesive steel 900ml price is only 35 yuan.
Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!
Stick steel adhesive use method
Sticking steel reinforcement construction points: concrete and steel plate surface treatment → reinforcement member unloading → preparation of SHB-bonded steel structure glue → gluing, pasting → fixing, pressurization → curing → unloading support → quality inspection → antisepsis, sealing treatment
Stick steel construction steps
Construction process
Surface treatment of concrete and steel parts → Selection and production of fixed components → Preparation of adhesives for sticking steel building structures → Application of adhesives and adhesive steel plates → Fixation, pressurization, solidification → Removal of fixed and pressurized components → Quality inspection → Surface protection and corrosion protection → Acceptance acceptance
Construction process
1 Adhesive surface treatment: The concrete surface is polished with an angle grinder until a new surface is exposed, and the dust is removed; the steel plate is roughened by an angle grinder.
2 the preparation of fixed components: According to the processing process requirements and different parts of the paste situation, choose a different method of fixation.
3 adjust the glue: First, the A, B components were mixed uniformly, and then the A, B components were poured into the container according to a weight ratio of 4:1, with an electric stirrer or other bar uniform mixing, until the color consistency Up to now, it is generally preferable to adjust the amount of rubber 6-10kg at a time.
4 Bonding: Stir the even glue, and apply to the surface of the adherend. Generally, the glue layer is 2mm thick, and the middle thickness is thin. Then, it is bonded and pressed to make the glue overflow from the surroundings. After 24 hours, pressurizing and fixing facilities can be unloaded.
5 Inspect the adherends and construction quality and perform surface preservation and other modification treatments.
Editor's summary: This is the knowledge of the formula of adhesive steel. Many of the above-mentioned knowledge are theoretical knowledge. Many people may find it difficult to understand, because they are all knowledge of textbooks, but for some professional construction work. In terms of friends, these contents are the knowledge that must be mastered. Only by knowing the basic knowledge can we know how to put it into practice. Therefore, there are many things in our lives that we need to learn because we only have to constantly learn from them. Learn in order to improve yourself.
