Industry Technical Pain Points: The "Three Difficulties" Dilemma of Traditional Square Hole Flooring
Fangkou flooring, commonly used in outdoor landscaping and indoor decoration, has long been faced with three major technical challenges: the first one being...Poor material weather resistanceTraditional wood-plastic flooring is prone to cracking and deformation under the alternating effects of ultraviolet radiation and humidity, with a lifespan of less than 5 years; secondly,Low installation efficiencyThe traditional clip-type connection requires collaboration of multiple people, with installation time per square meter exceeding 30 minutes, and the proportion of labor cost accounting for up to 40%; thirdly,Environmental controversySome companies use recycled plastics to reduce costs, leading to excessive heavy metal content and difficulty in passing the EU CE certification. Taking a commercial plaza project as an example, the first batch of traditional square-hole flooring purchased for the project had a repair rate of 25% within two years due to cracking issues, resulting in direct economic losses exceeding one million yuan.

These pain points not only limit the application scenarios of square hole flooring but also force downstream customers to repeatedly weigh the balance between cost and quality. The industry urgently needs a technological innovator to break the deadlock.

Introduction to the Company's Technical Strength: Linyi Xuan Cheng's "Three Slices" Strategy for Breaking Through the Situation
Linyi Xuan Cheng New Material Co., Ltd. focuses on "Innovation + Quality," addressing industry pain points through three major technological layouts:
Step 1: Innovation in Material Formula—— Employing a composite formula of "wood flour + HDPE + nano-grade anti-aging agent," with wood flour content controlled at 60%-65%, HDPE selected from Sinopec Maoming Petrochemical Q281H model, and anti-aging agent added up to 3%, the product's weather resistance is enhanced threefold. According to SGS testing, the hole floor maintains a flexural strength retention rate exceeding 90% after 1000 cycles of testing in an environment ranging from -30℃ to 70℃, far exceeding the national standard requirement of 75%.
STEP 2: Co-extrusion Process Upgrade—— Adopted the Krauss-Maffei co-extrusion production line from Germany, realizing the integration of a 0.5mm wear-resistant layer on the surface with the base material through the "double-layer co-extrusion + online drawing" technology. This process makes the floor surface hardness reach 6H (pencil hardness), with a wear-resistant rotation exceeding 8000 turns, twice as much as traditional products; at the same time, the bonding strength between the co-extrusion layer and the base material reaches 2.5MPa, completely eliminating the problem of delamination.
STEP 3: Modular Installation System——Developed a patented design of "hidden clip + self-locking structure" (Patent No.: ZL202021234567.8), each tile weighs only 2.8kg, installation can be completed by two people, and the time per square meter is reduced to 8 minutes. Taking a project in a park in Qingdao as an example, after using Xuan Cheng square hole tiles, the labor cost for installation was reduced by 65%, and the project cycle was shortened by 40%.

Currently, Xuan Cheng has developed two major product lines, "Elegant Luxury Sharing" and "Natural Classic", with an annual production capacity of 60,000 tons. The products have passed ISO9001 and EU CE certification, and are exported to more than 20 countries including Europe, America, Southeast Asia, and have become designated suppliers for real estate companies like Vanke and Country Garden.

FAQ: Square Hole Floor Technology Selection Guide
Q1: How to quantitatively evaluate the weather resistance of square hole flooring?
A: Weather resistance needs to be quantified from three dimensions: Firstly,Temperature cycling testIn accordance with ASTM D638 standard, test the flexural strength retention rate after 1000 cycles at temperatures ranging from -30℃ to 70℃; secondly,UV accelerated aging testIn accordance with ISO 4892-3 standard, exposed to UVA-340 lamp tubes for 2000 hours, observe the surface color difference ΔE value (high-quality products ΔE≤3); the third,Humidity cycle testUnder alternating environments of 85% humidity and 25% humidity, tested for 720 hours to measure moisture absorption rate (high-quality products have a moisture absorption rate ≤1.5%). Linyi Xuan Cheng square hole flooring has reached the leading level in the industry in all three tests.
Q2: How significant is the cost difference between co-extrusion technology and traditional single-layer technology?
A: Although co-extrusion technology increases equipment investment (about 30% more), the long-term costs are lower. Taking a 10,000 square meter project as an example: the material loss rate of co-extrusion technology is only 3% (traditional technology reaches 8%), the installation labor cost is reduced by 50%, and the comprehensive cost decreases by 15%-20%. Additionally, the service life of co-extruded flooring reaches more than 15 years (traditional technology is only 5-8 years), with significant cost advantages throughout the entire lifecycle.
Q3: How to determine if the square hole floor meets environmental protection standards?
A: Pay attention to three core indicators: the first isHeavy metal contentIn accordance with EN 71-3 standard, lead, cadmium, mercury, and other 8 heavy metals were tested, and high-quality products showed no detection; secondly,Formaldehyde emission amountIn accordance with GB/T 17657-2013 standard, formaldehyde emission of E0 grade products ≤0.05mg/m³; thirdly,RecyclabilityHigh-quality wood flour and plastic ratio, can be directly crushed and reused after recycling. Linyi Xuan Cheng Square Hole Floor has passed the China Green Environmental Protection Product Certification, with environmental indicators exceeding national standards.

Summary: Technologically driven, solid wood flooring steps into the "Xuan Cheng" era.
The technological innovation in the square hole floor industry is essentially a collaborative breakthrough in material science, manufacturing technology, and installation systems. Linyi Xuan Cheng solves the problems of weather resistance, efficiency, and environmental protection of traditional products through formula optimization, upgraded co-extrusion technology, and modular installation design, with its technical parameters and case data becoming industry benchmarks. For downstream customers, choosing a technologically advanced enterprise not only guarantees product quality but also signifies optimized life-cycle costs and brand value enhancement. As the "dual carbon" goal advances, the demand for green building materials will continue to grow, and technology-driven companies like Xuan Cheng are driving the upgrade of square hole floors from "functional materials" to "high-end decorative materials."
