1. Wood plastic floor WPC is compared with stone plastic floor SPC. WPC combines the waterproof and stability of LVT, and is also as easy to install as laminate floor. With the increase of cork and EVA pad, the foot feel and sound insulation effect will be better than LVT lock floor.
WPC uses all environmentally friendly materials, which will be more environmentally friendly than laminate flooring.
In short: WPC has the advantages of LVT and laminate.
WPC: woodplastic composition = lvtlayer + wpccore
The LVT layer and WPC layer of WPC are bonded by glue, and the peel strength is very good, even better than the bonding strength of LVT color film and frosted sheet after hot pressing
2. The stability of WPC is better than that of PVC
WPC floor in the high temperature of 80 degrees plus or minus 2 degrees for 6 hours, take out the normal temperature of 23 degrees plus or minus 2 degrees, 50% humidity for 24 hours observation. The conclusions are as follows
The shrinkage of length is 0.11%
The shrinkage of width is 0.07%
2. Advantages of WPC
The price of WPC is gold grade. The price of 5.5mm WPC is basically the same as that of 5.0mm lock and glue free products of vinyl, but it is higher than that of magic buckle, and much higher than that of washed glue and ordinary PVC floor (brush glue type).
The installation cost of WPC is far lower than that of ordinary brush glue PVC floor, lower than that of ordinary PVC lock lock floor, no glue PVC floor, magic buckle and washing glue PVC floor.
WPC’s waterproof is quite good, wood plastic this layer of waterproof is also very stable, on the contrary, magic buckle, washing glue, ordinary brush glue PVC floor, because it involves glue, waterproof effect is general.
The installation convenience of WPC is relatively convenient due to the installation method of angle tap. It is suitable for DIY. Of course, the price of dry back is the worst.
WPC floor is certainly good in terms of silence and foot feel, especially the WPC floor with cork or EVA pad;
WPC is also very good in environmental protection, including formaldehyde emission, heavy metals, especially reach test, 144 items all passed.
WPC flooring is weak in recyclability after use, because WPC (wood plastic) can not be recycled and reused. PVC flooring of other products can be recycled and reused as recycled materials
3. Several problems in communication between WPC and customers
(1) Because the LVT layer of WPC is generally only 1.5mm thick, the plate pattern should be flat as far as possible. Do not do hand grasping and classicslate (plate pattern), and the rate of defective products will be very high.
(2) The cost of 6.0 mm wood plastic layer is 1.8 US dollars per square meter higher than that of 5 m wood plastic layer
(3) The LVT layer and WPC layer of WPC are bonded by glue, and the peel strength is very good, even better than the bonding strength of LVT color film and frosted sheet after hot pressing
(4) Some WPC sizes may mention that they need a width of 143mm. Our products used to have the same width. However, after testing and experience in large-scale production, the loss of 143mm will be larger, so it is changed to 146mm. Less wear means low cost.
(5) When preparing WPC samples, especially when the whole sample is needed, please be sure to assemble them by yourself to see if there is any problem. In the early stage, some samples are defective, and it is OK to make small samples, but the whole sample may have some problems, such as height difference, oblique head seam, etc., so please confirm and send them again. Otherwise, the effect will be even worse.
2、 Stone plastic floor SPC:
Stone plastic flooring (SPC) is a new type of environmental protection floor developed based on high technology. It has the characteristics of zero formaldehyde, mould proof, moisture-proof, fire-proof, insect proof and simple installation. SPC floor is a kind of product made of PVC base material extruded by extruder combined with t-mold, PVC wear-resistant layer, PVC color film and PVC base material are respectively heated and pressed by three roll or four roll calender at one time. The process is simple, and the lamination is completed by heat without glue. SPC flooring materials use environmental protection formula, do not contain heavy metals, phthalates, methanol and other harmful substances, in line with en14372, en649-2011, iec62321, gb4085-83 standards. It is popular in the developed countries in Europe and America and in the Asia Pacific market. With its excellent stability and durability, the stone plastic floor not only solves the problem of damp deformation and mildew of solid wood floor, but also solves the formaldehyde problem of other decoration materials. It can be used in many public places, such as indoor decoration, hotels, hospitals, shopping malls and so on.
Shrinkage of SPC floor: ≤ 1 ‰ (after tempering), ≤ 2.5 ‰ (before tempering), (shrinkage test standard: 80 ℃, 6 hours);
SPC floor density: 1.9 ~ 2 T / m3;
Advantages of SPC floor: the physical indexes of SPC floor are stable and reliable, and the chemical indexes meet the international and national standards;
Disadvantages of SPC floor: high density, heavy weight and high transportation cost of SPC floor;
Compared with LVT and WPC flooring, SPC flooring is simple in processing and manufacturing.
Advantages of SPC environmental protection floor:
SPC floor is a new type of environment-friendly composite product, which has the following advantages:
(1) Waterproof and moisture-proof. It can be used in the environment where traditional wood products cannot be used;
(2) It can prevent insects and termites, effectively eliminate insect disturbance and prolong service life;
(3) There are many colors to choose from. It not only has natural woodiness and wood texture, but also can customize the color according to your own personality;
(4) Strong plasticity, can be very simple to achieve personalized modeling, fully reflect the personality style;
(5) High environmental protection, pollution-free, pollution-free, recyclable. The product does not contain benzene and formaldehyde. It is an environmental protection product and can be recycled, which greatly saves the use of wood. It is suitable for the national policy of sustainable development and benefits the society;
(6) High fire resistance. It can effectively retard the fire and has a fire rating of B1. It can extinguish itself in case of fire and does not produce any toxic gas;
(7) Good machinability, can be ordered, planed, sawn, drilled, the surface can be painted;
(8) Simple installation, convenient construction, no complicated construction technology, save installation time and cost;
(9) No crack, no expansion, no deformation, no need to repair and maintenance, easy to clean, save later repair and maintenance costs;
(10) Sound absorption effect is good, energy saving is good, so that the indoor energy saving can reach more than 30%;
(11) Compared with LVT / WPC floor, SPC floor has less investment cost, quick effect, less labor intensity and clean environment.
SPC floor production process:
Process: 1. Mixing
According to the proportion of raw materials automatic metering → high-speed mixer hot mixing (hot mixing temperature: 125 ℃, the role is to mix all kinds of materials evenly, remove moisture in the materials) → into the cold mixing (to cool the materials, prevent caking and discoloration, cold mixing temperature: 55 ℃.) The material is mixed evenly by cooling;
Process 2: extrusion
The formed sheet passes through a four roll calender, and the base material is fixed in thickness, pasted with color film, pasted with wear-resistant layer, cooled and cut;
Procedure 3: UV tempering
Surface UV → tempering (tempering hot water temperature: 80 ~ 120 ℃); Cold water temperature: 10 ℃)
Procedure 4: slitting and slotting + Packaging
Slitting → slotting, trimming, chamfering → inspection → packaging
