Feasibility report of wall putty and how to make wall putty
Ant Construction not only provide customers high quality internal and external wall putty formula, but also provide high quality wall putty production machine. Ant Construction specialize in production, selling and construction of wall putty and wall production machinery for more than 20 years, product performance is continuously improved, so the cost is low and the investment risk is small.
Choose the exact right and suitable wall putty mixer for production of good quality putty powder.
The price of wall putty production machinery is cheap, many people think that it is enough to mix the powder materials with a machine that can stir, they use ordinary mixers or vertical feed mixers, as a result, the wall putty quality was bad and can not sell the wall putty at a higher price. According to many years of production practice, Horizontal ribbon wall putty mixer has high mixing accuracy, high efficiency, low electricity consumption, convenient installation, less dust and small noise. The daily output can be 20 tons using a 1 ton simple small wall putty production line, and only around 5000USD of equipment investment costs are needed. Let me tell you about the precautions for wall putty production:
Precautions for wall putty production
Sample test: In a strong transparent plastic bag, put 1000g of the putty powder that needs to be mixed into the bag. Blow the bag up and shake for more than 5 minutes. Be careful not to leave any residue on both sides of the bag. For example: waterproof polymer powder to make waterproof wall putty, the method is to take 250 grams of hydrated lime powder, 750 grams of calcium carbonate powder, 4-6 grams of waterproof polymer powder (depending on the quality of local calcium powder) into a transparent plastic bag, and air-tighten Shake it evenly for 5 minutes, then put it into a container, add about 400 grams of water (stir it into a paste suitable for construction), leave it for 5 minutes, and then stir for use.
Regarding ordinary polymer powder and waterproof polymer powder for interior walls, generally speaking, the more of the polymer, the higher bonding strength and the better workability and water retention, but too much polymner will weaken the leveling properties, add about 1% sodium bentonite can adjust the leveling feature.
Common polymer powder for internal wall putty has chemical reacts with lime powder, white cement, and gypsum powder, that means waterproof putty powder cannot use commoan polymer powder. Therefore, after the production of ordinary internal wall putty, if you want to produce waterproof putty, you must remove all the residual powder from the feeder and putty powder mixer before producing another one.
The internal wall waterproof polymer powder cannot produce ordinary putty, because the cost is too high.
Talc powder can be used to replace part of heavy calcium powder.
The main component of hydrated lime powder is Ca(OH)2. The greater the amount added, the greater the hardness. Generally, it can be added between 15-40%. If it is too little, the waterproof effect will be poor. If it is too much, it is easy to crack and show yellow. If the wall putty get yellow, can be solved by adding calcium sulfate to denaturate, if crack resistance is required, celluelose fiber can be added to the inner wall, wood fiber or polypropylene fiber can be added to the outer wall, which can increase the anti-cracking effect without increasing the cost.
Waterproof glue powder can also be used as exterior wall putty and gypsum paste. External wall waterproof glue powder produces exterior wall waterproof putty, and anti-crack glue powder produces exterior wall flexible putty, thermal insulation mortar, dry-mixed mortar tile adhesive, tile grout and various dry powder adhesives.
The white cement in the exterior wall formula can also be replaced by black cement. Quartz sand is not only a filler, but also has anti-cracking, thickening, and waterproof effects. Cement sand can be used instead of quartz powder, wollastonite powder, or heavy calcium powder.
The gear oil must be added to the horizontal putty powder mixer before using it for the first time. The motor rotates in a clockwise direction. In the future, all bearings must be frequently lubricated.
Clean the wall during construction to ensure that there is no floating dust, stains and other debris. The wall must be dry, solid and flat. Then use a scraper to scrape the putty twice, first scrape for leveling the construction surface, after the surface 80% or 90% dried and then scrape the second time.
The raw material cost and selling price profit margin of putty powder for interior and exterior wall series:
Ordinary putty powder for interior walls raw material cost 55USD market price 100 yuan
Special-grade putty powder for interior walls raw material cost 60USD market price 120USD
Internal wall waterproof putty powder raw material cost 70USD market price 130USD
External wall waterproof putty powder raw material cost 80USD market price 160USD
External wall flexible putty powder raw material cost 135USD market price 250USD
Putty paste is to mix putty powder with 2:1 cold water and mix it evenly. The market price is basically the same as that of putty powder, and the cost is reduced by half compared with putty powder. Considerable profit, low investment cost (a horizontal putty powder mixer), putty powder is definitely a good investment project.
