After you have determined the construction plan of an HPL cubicle partition project, will you pay attention to the key element of this plan-the partition accessory used in the construction!
If you choose plastic parts, can you tell the real nylon parts or PP parts?
At present, there are many styles of sanitary partition accessories available on the market, with different varieties, including alloy, stainless steel and plastic materials. Most of the plastic parts are made of two raw materials: polypropylene (commonly known as PP) and PA (commonly known as nylon).
1. Comparison of the Nylon and PP materials
PP is a crystalline plastic with lightweight, but insufficient high-temperature rigidity, low-temperature brittleness, poor environmental resistance, high tensile strength anisotropy, easy deformation of products, high creep properties, and not long-term load resistance. PA is the abbreviation of Polyamide in English. It is an important engineering plastic, and its output ranks first among the five general engineering plastics. Compared with general plastics, it has the advantages of wear resistance, toughness, heat resistance, cold resistance, corrosion resistance, and non-toxicity. It has high tensile strength and impact strength at room temperature, and it can be used in a wide range of temperatures, generally up to -40°C-100°C. Therefore, from the point of view of material characteristics, sanitary partition accessories made of nylon materials are significantly better than PP accessories in terms of durability.
2. The price comparison of the Nylon and PP materials
At present, the price of nylon raw materials is about three times that of PP, and the production process is relatively complicated, so the price of partition parts made of nylon materials will be more than three times more expensive than that of PP.
3. How to distinguish the Nylon and PP material
When the two look the same, the average user is more likely to confuse whether the material of the partition accessory is PP or nylon, especially when the two materials cannot be compared at the same time. As a result, some merchants on the market will even point out that they sell PP materials at the price of nylon materials, misleading some customers, and at the same time planting hidden quality problems for the toilet project. How to distinguish between PP and nylon, in fact, can use two simple methods: 1. Visual appearance method. Partition accessories made of nylon material look shiny and shiny, and can maintain a long-term luster, feel heavy and strong, the longer they use, the stronger the toughness, while the PP material accessories, its color and brightness will be slightly dull. It is more obvious after less than 1 month of use, and the weight is relatively light. 2. Combustion method. Take a small amount of the sample to be distinguished and burn it with fire. Nylon will release a fragrant gas, and PP will release a fishy gas when burned.
Although PP accessories have many shortcomings, it can even be said that PP is not suitable for HPL cubicle partition accessories, but there are still many customers using these accessories. The main reason is that the cost of PP accessories is relatively low. However, as a sanitary partition project, the cost of accessories actually accounts for a very small proportion of the project cost, and it is very important. Therefore, in addition to the construction cost factor, it is more important to consider the quality of the project. If it is because of the desire to save a little accessories cost The choice of PP partition accessories may often affect the quality of the entire project. This situation is especially obvious in the northern region. Due to the extremely cold winter weather in the northern region, if the fixed sanitary partition is assembled with PP accessories, these accessories are easy to be brittle and not resistant to load due to the characteristics of the material itself. It is easy to deform, the bracket is easy to break, and the toilet may collapse in serious cases. This will not only cause inconvenience to users but also the construction unit will need to rework frequently because of this. It is important to know that frequent rework actually increases the cost of construction, and the result may be “stealing the chicken without losing the rice.” Therefore, when carrying out projects in areas where severe cold and low temperatures are likely to occur, it is best to use high-quality nylon accessories, because nylon material can withstand severe cold and its toughness will increase with the use of time.
In the case of little influence by temperature changes, even if the engineering construction uses PP accessories, better quality PP accessories should be selected. At present, many accessories on the market are made of inferior recycled materials. Although the price is relatively affordable, the quality is very poor. Not to mention long-term use, even if it is installed, it may not stand the test, and it will easily become brittle. crack. In addition, when choosing accessories, users and construction units should pay attention to the quality of some parts, such as door hinges, door locks, and foot brackets that support the board that are frequently movable in the use of sanitary partitions. The quality of the product is the most critical. To choose this kind of product, it is recommended to choose some manufacturers with a good reputation for product quality in the industry.
All in all, a high-quality project cannot do without good accessories. Both the user and the construction unit should pay attention to this and carefully select it, so as not to lose the “watermelon” because of the “sesame”.
