Phenomenon: Wall cracking, cracking
Analysis: There are many causes of cracks in the wall surface. There are four main types: 1. The construction process is not closed. Such as in the grooved wiring place, do not follow the formal process, perfunctory. 2. The ground floor subsidence and earthquake are encountered on the floor. 3. The building's insulation wall is informally treated. Because the insulation wall is a block-block-spliced ​​joint, if there is no formal process, it will cause wall cracks. 4. There is a problem with the cement paint layer. Such as the proportion of cement and sand, moisture content is not in place and so on.
Solution: For wall cracks that occur due to slotting and foundation sinking, etc., construction must be strictly in accordance with the procedure: first, grind the plaster and fill it with a plaster, and then apply a bandage or cloth to the grooved part or the cracked part. Kraft paper, followed by other primary treatment. Non-standard processes do not use kraft paper at all, but instead direct brushing. Over time, cracks are inevitable.
Phenomenon: white floc appears on the paint surface
Analysis: Mainly because of the dampness of the walls. The reason for the dampness is that there are two kinds of reasons: either the wall is damp or the building is built with excessive moisture. The result is time-long, the walls will reveal the alkali in the cement, showing the phenomenon of lumping and packing.
Solution: Before painting, make sure the wall treatment is completely dry. Two weeks later, the walls were thoroughly dried and a primer was applied to the walls. If the lacquer has been brushed and split, the lacquer must be completely scraped to ensure that the wall is dry and repainted.
Phenomenon: wall packs
Analysis: mainly caused by construction process. Solution: In the renovation, we must first scrape all the paint on the original wall surface, and then brush a layer of wall interface agent to prevent the putty and the new putty in the cracks, "double insurance" after the end of the process , and then proceed with other processes. In addition, the ash on the wall must also be cleaned, otherwise there will be bulging and so on.
Phenomenon: White walls are yellow and black
Analysis: There are several cases of discoloration, such as the white wall. Apart from the problems of the paint itself, there is a clear relationship with the worker's level and effort. If the force is not uniform, the wall will not feel smooth. Another - a key factor is the color of the wall, in the smear of paint with color, due to uneven color, the result will appear - the beginning of the brush where the color is light, behind the brush where the color is dark, so when the brush should pay attention Stir evenly.
Solution: Improve the level of craftsmanship. When applying colored paint, be sure to constantly stir to make the color even. The high quality of the purchase, especially the use of specially formulated wall lacquer, allows the color of the wall to be long-lasting and can be washed with water to keep the wall clean.

HFCs (hydrofluorocarbons) are the third
generation of fluorine-based gases.
These products are categorised as having zero ODP (Ozone Depleting Potential)
and medium to high GWP (Global Warming Potential) and so offer a more
environmentally friendly alternative to CFCs and HCFCs.
HFCs are used in a wide range of refrigeration and air conditioning equipment
specifically designed for them, and as "drop
in" retrofit gases for older CFC or HCFC equipment. HFCs are also
used in selective propellant and foam blowing
applications.
A growing focus on the environmental
impact of refrigerants is fuelling demand for refrigeration solutions
that can provide satisfactory cooling performance with a lower impact on global
warming. This is propelling environmentally friendly refrigeration solutions to
the top of the corporate sustainability agenda. In addition, local legislation
is increasingly targeting refrigerant gases with high GWP.
Zhejiang Zhonglan Refrigerants Co.,Ltd offers a number of lower GWP HFC solutions, such as R134a, R404a, R406a, R407c, R410a, R507,R417a,R422d,R125,R32, etc. For new equipment purchases, we also supply a wide range of HFC alternatives. These include HC(natural refrigerants), which provide a viable, lower GWP alternative to HFCs.
