1.  5 common expression methods for plastic flooring
1.1 PVC: poly vinyl chloride,
1.2 LVT: luxury vinyl tile,
1.3 LVP: luxury vinyl plank
1.4 Vinyl floor
1.5 Vinyl plank
1.6 WPC:wood plastic composite
1.7 SPC: stone plastic composite, European and American countries call this floor RVP (rigid vinyl plank), rigid plastic floor.
2. Classification of plastic flooring
 
At present, PVC sheet flooring can be made into two kinds, one is that the pattern material from the bottom to the surface is the same homogeneous and translucent floor. If the surface is burnt out or scratched, it can be repaired by polishing with a sander. . The other is that the uppermost layer is a pure PVC transparent layer and then a combination of a printed layer and a foamed layer is added below. It can be seen that the same quality of the core material is much superior to the composite type.
From the morphological point of view, it is divided into coil floor and sheet floor; the products highlighted in this article: LVT, WPC floor is semi-rigid sheet plastic floor, and SPC (RVP) floor is hard sheet floor. At present, there are three main types of LVT flooring: vinyl locking, dry back, loose laying. From another perspective, PVC flooring can be divided into: Dry Back locks (Loose lay). At the same time, WPC wood plastic flooring and SPC stone plastic flooring are also in the active promotion and high-speed development stage in the domestic and foreign markets.
 
2.1 Comparison of dry back and loose lay in plastic flooring
 
2.1.1 Same point: Both belong to PVC floor, the specifications are the same, and some parts are the same size;
 
Dry back mainly has eight specifications of 942*157, 1227*157, 1227*187, 1227*235, 914.4*101.6, 470*470, 608*308 (unit: mm);
 
The loose lay mainly has 942*157, 1227*157, 1227*187, 1227*235, 470*470, 608*308 (unit: mm).
 
Click mainly has 936*150, 1220*150, 1220*180, 1220*228, 1500*228, 600*300 (unit: mm) These specifications, pay attention to compare with dry back.
 
WPC currently has two specifications 1217*146, 1217*178, 596*296 (unit: mm).
 
SPC mainly has: 1210*150, 1210*181, 203*1219, 178*1219, 152*1219 (in millimeters)
 
2.1.2 Differences
 
A. Installation method: dry back requires the use of glue, etc., also known as glue down, loose lay directly on the pavement (loose lay on the bottom layer with a layer of black leather, placed on the plane can not move.)
B. Thickness: dry back Our factory only starts from 2.0mm thick bottom. If it is lower than this specification, loose lay is generally consistent with Click 4.0mm, 5.0mm
C. Wear-resisting layer: Under normal circumstances, we now do 2.0 mm and 2.5mm thick Dry back, wear-resistant 0.1mm-0.5mm, 3.0mm thick Dry Back, wear-resistant 0.1mm-1.0mm, 2.0mm And the principle of 2.5mm can do more than 0.5mm wear resistance, but it is not cost-effective. In addition, the formulation of the bottom material and the middle material have to be changed and tested. Now the factory basically does not do; loose lay now, The wear layers of 4.0mm and 5mm are basically only wearable for 0.3mm and 0.5mm, for the same reason.
D. Price: dry back is cheap, loose lay is more expensive
E. Health time: dry back requires 24 hours of health after tempering. Looselay is the same as the lock series, which takes 48 hours.
F: The flexibility of the two is different. The loose lay product is obviously much softer than the dry back. Such characteristics can also be used as a distinguishing feature. At the same time, the most obvious is that there is a layer of black leather at the bottom of the loose lay, which can be distinguished by soft and hard using a nail scraping test.
3, the composition of the plastic floor
 
PVC floor composition: PVC resin powder, stone powder, stabilizer, carbon black, the main components are polyvinyl chloride and stone powder.
The plastic floor is composed of a backing layer, a core layer, a glass fiber, a decorative paper and a wear layer from bottom to top.
 
3, PVC certification
At present, PVC products are certified by Floor score, DIBT, CE, ISO14001: 2004 and ISO9001: 2008, TÜV Rheinland.
 
5, PVC's most critical product indicators
• Stability: product shrinkage expansion rate 80 ° C 6 hours. 0.25%, 0.15% (line standard)
 
• Heating warpage: 80°C 6 hours EN<2mm; Enterprise standard: 1.2mm (dryback); 1.0mm (click); 0.5mm (loose lay)
 
• Lock pull: normal temperature (23 ° C) 5.0mm> 13-15kgs / 5cm.
 
• 4.2mm>12kgs/5cm.
 
• If the short side is V buckle, 4.2mm>15-18kgs/5cm.
 
• Peeling strength: the bonding strength of the color film and the middle material
 
• Scratch resistant, wear resistant
 
• Brightness: 10+/-2.
 
6, floor purchase area calculation: If the area required for paving is 50 square, because the floor to the corner needs to be saw off a part, and the general floor loss rate is 5%, so the actual area is 50 * (1 + 5%) = 52.5 square.
Second, the advantages and disadvantages of LVT floor:
 
6 major advantages:
1. Green environmental protection
The main raw material for the production of PVC flooring is polyvinyl chloride. Polyvinyl chloride is an environmentally friendly and non-toxic renewable resource. It has been used in people's daily life, such as tableware and medical infusion tube bags. Its environmental protection is unnecessary. worried.
 
2, super wear-resistant
The surface of the PVC floor has a special layer of PVC wear-resistant layer, and its wear-resistant number can reach 300,000 rpm. According to the different thickness of wear resistance, it can be used for 5-10 years under normal conditions. The thickness and quality of wear layer directly determine the use time of PVC floor. The standard test results show that the wear layer of 0.55mm thick can be under normal conditions. After more than 5 years, the 0.7mm thick wear-resistant layer is enough for more than 10 years, so it is super wear-resistant. Because of its superior wear resistance, PVC flooring is becoming more and more popular in hospitals, schools, office buildings, shopping malls, supermarkets, transportation and other places with large traffic. (The wear resistance of the wear layer is currently mainly measured by measuring the loss, that is, the mass reduction)
 
3, high elasticity and super shock resistance
The PVC floor is soft in texture, so it has good elasticity. It has good elastic recovery under the impact of heavy objects. At the same time, PVC floor has strong impact resistance, and it has strong elastic recovery for heavy impact damage and will not cause damage. The excellent PVC floor can minimize the damage of the ground to the human body and can disperse the impact on the foot. The latest research data shows that the staff fell when the excellent PVC floor was paved in a space with a large flow of people. And the rate of injuries is nearly 70% lower than other floors.
 
4, fire retardant
The qualified fireproof index of PVC floor can reach B1 level, and the B1 grade means that the fire performance is very good, second only to stone. It is extinguished from the fire.
 
5, easy maintenance
The maintenance of the PVC floor is very convenient, and the floor is dirty and wiped with a mop. If you want to keep the floor lasting, you only need to do regular waxing maintenance, and the maintenance frequency is much lower than that of laminate flooring.
 
6, waterproof and moisture proof
Since the main component of PVC flooring is vinyl resin and has no affinity with water, it is naturally not afraid of water. As long as it is not soaked for a long time, it will not be damaged; and it will not be mildewed due to high humidity.
 
2 disadvantages:
 
Non-natural materials, high requirements for the base floor (the base layer must be flat, solid, dry when the LVT floor is laid, the surface of the plastic floor is smooth, the yin and yang angles are square, no ribs, no oil, dust and impurities).
 
Third, wood plastic floor WPC
WPC combines the waterproof and stability of LVT and is also easy to install like a laminate flooring.
The addition of cork and EVA mats, foot feel and sound insulation are better than LVT's lock floor.
WPC uses environmentally friendly materials that are more environmentally friendly than laminate flooring.
In short: WPC between LVT and Laminate, both have the advantages.
1. Composition
WPC : Wood Plastic Composition=LVT Layer + WPC Core
1.1.1 WPC LVT layer and WPC layer are glued, the peel strength is still very good, even better than the LVT color film layer and frosted sheet after hot pressing
The stability of WPC is better than PVC:
 
The WPC floor was taken at a high temperature of 80 degrees plus or minus 2 degrees for 6 hours, and was taken out at a normal temperature of 23 plus or minus 2 degrees, and observed at a humidity of 50% for 24 hours. Concluded as follow:
 
Length shrinkage is 0.08%
 
Width shrinkage is 0.05%
 
Warpage: 0.25mm
 
LVT: 0.08-0.15%
 
Warpage: 0.5-1.2mm
 
2, the advantages of WPC
 
WPC Engineered Vinyl Flooring - WPC's price is gold-grade, WPC's price of 5.5mm is basically the same price level as Vinyl's 5.0mm lock and glue-free product, but higher than the magic buckle, and far higher For washing glue and ordinary PVC floor (brush type);
 
WPC installation cost is far lower than ordinary brushed PVC floor, lower than ordinary PVC lock floor, and glue-free PVC floor, magic buckle and washable rubber PVC floor installation cost is not much difference;
 
The waterproofness of WPC is quite good, and the waterproofness of wood-plastic layer is also very stable. On the contrary, magic buckle, water-washing glue, ordinary brush-type PVC floor, because of the glue involved, the waterproof effect is general;
 
Easy to install, WPC is relatively easy to use because it is the installation method of Angle-Tap. It is suitable for DIY. Of course, the Dry back that needs to be brushed separately is the worst at this point.
 
The WPC floor is definitely good for quietness and foot feel, especially WPC flooring with cork or EVA mats;
 
WPC is also very good at environmental protection, including formaldehyde emission, heavy metals, especially Reach test, and 144 items are all passed.
WPC has good sound absorption and good energy saving, which makes indoor energy saving up to 30%.
 
WPC is simple to install, convenient to construct, does not require complicated construction techniques, and saves installation time and cost.
 
WPC flooring is weak in terms of recyclability after use, because WPC (WoodPlastic) cannot be recycled and reused. PVC flooring of other products can be reused as a return material.
 
3, several issues that need to be paid attention to in WPC and customer communication
 
(1) Because the LTV layer of WPC is generally only 1.5mm thick, the plate pattern should be as flat as possible. Do not do the hand and the classic slate (slate pattern).
 
(2) The cost of the 6.0MM wood-plastic layer is 5.0 dollars higher than the 5.0MM wood-plastic layer.
 
WPC+2.0mm EVA Form : Price +USD1.00SQM
 
WPC+1.5mm Cork : Price +USD1.50SQM

Fourth, stone plastic floor SPC:
 
SPC (Stone plactic composite) is a new environmentally-friendly floor based on high-tech, featuring zero formaldehyde, mildew proof, moisture proof, fireproof, insect proof and simple installation. SPC floor is extruded from the extruder with T-die to extrude the PVC substrate, and the three-roll or four-roll calender is used to respectively wear the PVC wear-resistant layer, PVC color film and PVC substrate, and heat-fit and emboss the product once. The process is simple, the fit is done by heat, and no glue is needed. SPC flooring materials use environmentally friendly formulations and do not contain hazardous substances such as heavy metals, phthalates, methanol, etc., in accordance with EN14372, EN649-2011, IEC62321, GB4085-83 standards. It is very popular in 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 moisture deformation and mildew of the solid wood floor, but also solves the formaldehyde problem of other decoration materials. It has a wide selection of designs, suitable for indoor home improvement, hotels, hospitals, shopping malls and other public places.
SPC floor shrinkage: ≤1‰ (after tempering), ≤2.5‰ (before tempering treatment), (shrinkage test standard: 80°C, 6 hours standard);
 
SPC floor density: 1.9~2 tons/m3;
 
SPC floor advantages: SPC floor physical indicators are stable and reliable, and chemical indicators meet international and national standards;
 
SPC floor defects: SPC floor density, heavy weight, high transportation costs;
 
Production of SPC flooring compared with LVT and WPC flooring: SPC flooring processing and manufacturing process is simple.
 
Advantages of SPC eco-friendly flooring:
 
SPC flooring is a new environmentally friendly composite product with the following advantages:
 
(1) Waterproof and moisture proof. It fundamentally solves the problem that wood products are prone to decay and swelling after being absorbed by moisture in humid and multi-water environments, and can be used in environments where traditional wood products cannot be used
 
(2) Insect and termite prevention, effectively eliminate insect harassment and prolong service life
 
(3) Colorful, there are many colors to choose from. It has both natural woody texture and wooden texture, and can be customized according to your own personality
 
(4) It has strong plasticity, can realize individualized style very simply, and fully reflects individual style
 
(5) High environmental protection, no pollution, no pollution, and can be recycled. The product does not contain benzene and formaldehyde. It is an environmentally friendly product. Recycling greatly saves the amount of wood used, and is suitable for sustainable national policy for the benefit of society;
 
(6) High fire resistance. It can be effectively flame retardant, the fire rating reaches B1 level, it will self-extinguish in case of fire, and it will not produce any toxic gas
 
(7) Good processability, can be ordered, can be planed, can be sawed, can be drilled, and the surface can be painted
