Putty on the market can be regarded as hundreds of kinds of products, with similar outer packaging, similar materials, and even similar prices.
In this confused putty powder market, how can we pick a good putty with high cost performance? ? We must first learn to distinguish between good and bad putty.
Have to learn to see
A good putty has clear graphics and text on the appearance packaging, with obvious manufacturer address, telephone number, certificate, etc.
, as well as the barcode and QR code of the produced product.
The manufacturer of the poor putty is not clear, and it is difficult to find the production date, certificate, etc.
of the product, not to mention the information such as barcode and QR code.
From the perspective of the product itself, the putty is white and delicate after opening the packaging bag, and the whiteness can reach more than 90.
The poor putty has not enough whiteness visually, and some even turn yellow and gray.
The hand feels rough, and there are impurities on a closer look.
Learn to smell
Good putty has no pungent odor after opening the package.
Putty is an environmentally friendly product, and its formula materials are strictly proportioned with good materials, and there will be no pungent phenomenon.
Poor products are environmentally friendly and have peculiar smells.
The reason for this phenomenon is that manufacturers use low-priced and inferior products for water-retaining agents and other organic solvents in order to reduce costs.
Judging from the scraping process
A good putty has smooth batching, good water retention, easy shaping and good gloss.
Unreasonable matching of fillers, such as improper use of the viscosity model of the water retaining agent, excessive amount of dressing, and too fine filler; secondly, it is easy to flange during batch scraping, and the drying time is too fast.
Quality comparison after putty construction
A good putty will not crack, powder, or leave the shell, moderate drying time, moderate hardness, and provide a convenient, smooth, white, and good adhesion base layer for the next process.
Poor putty coating film is dull, if the construction master is not skilled, does not understand the performance of the putty, the timing of the light collection is not accurate, or the operation of the light collection is improper, many quality problems are more likely to occur.
Poor putty film is prone to cracking.
The reason is that low dressing dosage in the putty, too high gray calcium powder dosage, too fine filler, and too high viscosity type of water retaining agent will cause the film to crack.
The coating film is easy to fall off, and the quality of the putty is caused by the following reasons: the amount of dressing is too low.
If the product is okay, the reason must be found from the construction.
If the putty is applied to the old film, the strength of the old film is low, or even It has been powdered, and the old coating film has not been completely removed before construction.
to sum up
After analyzing so many distinguishing techniques, do we have a deeper understanding of the quality of putty powder? How to choose high-quality putty powder? We can make the choice based on the putty's construction, environmental protection and craftsmanship.
