PVC building template-production problems and solutions
PVC building template-production problems and solutionsWith the fiery real estate industry in my country and the continuous construction of various projects, the PVC construction template industry has developed rapidly, and the industry prospects are optimistic! The market competition is extremely fierce. In this traditional industry, how to find their own market space, each PVC building template company is also seeking countermeasures.
So, what exactly do business owners who have been in the PVC building template industry for many years rely on to win the hearts of customers?
Is the price?
Is it quality?
Or service?
Quality has always been the easiest way to capture the hearts of customers. If you want to become a high-quality PVC construction template company, you must explore on the road of pursuing product quality, build a brand, and continue to develop. Despite the changing market, what remains unchanged is to guarantee products quality!
What should I do if I encounter product discoloration and deformation during production? :
1. There are many reasons for its discoloration: ultraviolet rays in sunlight, high temperature, oxygen, the pH of the air and the environment in which the product is located, etc.
How to prevent product discoloration can be started from the following aspects:
① As far as possible, choose materials and additives with small discoloration or good weather resistance, such as toner, color fastness, migration resistance, high temperature resistance, heat resistance, etc.
② Add some antioxidants and ultraviolet absorbers to improve the weather resistance of the products.
③ If the production and processing requirements are met, the processing temperature should be reduced as much as possible.
④ Spray weathering paint with good weather resistance on the front of the product.
⑤Coextrude a thin layer of material with good weather resistance on the front of the product.
2. The deformation is mainly due to the poor thermal deformation of the Vicat product. To improve the thermal deformation of the wood-plastic building template, the following aspects should be used: adding materials that do not affect the deformation of the wood-plastic building template, such as high-density oxidized polyethylene Wax OA9, as far as possible without adding materials that will affect the deformation of wood-plastic building templates such as low melting point lubricants, CPE, DOP, epoxy soybean oil, etc.
① Reasonable lubrication system and dosage.
② Reasonable production process such as production speed and cooling water temperature.
③How to reduce and release the internal stress of ecological wood products.
High-density oxidized polyethylene wax OA9 is a processing aid with excellent performance. The molecule contains hydroxyl and carboxyl groups, which can help compatibility with PVC. Because of its high viscosity, high crystallinity and acidity, it has a very obvious effect on plasticization. A small amount of addition can excellently promote plasticization. During the primary stage of extrusion, the stay time will be longer. The looseness of the ingredients makes the mixing more uniform.
In the late stage of extrusion, it will migrate to the appearance of the material and the metal, reflecting the external smoothness, and then has excellent metal peelability and good mold release.
High-density oxidized polyethylene wax OA9 is a high-temperature lubricant; its melting point is 132 ℃, environmental protection and non-toxic, in line with national environmental protection standards, it is an environmentally friendly product.
It is reported that high-density oxidized polyethylene wax is currently the only plastic lubricant that can have both internal and external lubrication (release effect), while maintaining a high degree of transparency, and has little effect on gelation.
