身為地板工廠(chǎng)的技術(shù)員，在長(zhǎng)期鉆研石晶地板的過(guò)程中，我深刻領(lǐng)悟到耐磨層厚度對(duì)于石晶地板的關(guān)鍵意義，毫不夸張地說(shuō)，耐磨層越厚越好。
先講講日常磨損場(chǎng)景下的顯著差異。我們?cè)谀M家庭客廳使用環(huán)境的實(shí)驗(yàn)室中做過(guò)測(cè)試，選用了兩款石晶地板，一款耐磨層厚度為 0.3mm，另一款達(dá) 0.6mm。在經(jīng)過(guò)相同的 10 萬(wàn)次桌椅移動(dòng)模擬摩擦后，0.3mm 耐磨層的地板表面出現(xiàn)了明顯的細(xì)微劃痕，湊近觀察，劃痕分布密集，用手觸摸能明顯感覺(jué)到凹凸不平；反觀 0.6mm 耐磨層的地板，僅出現(xiàn)少量極淺的擦痕，幾乎不影響視覺(jué)觀感，地板表面依舊光滑平整。這清晰地展現(xiàn)出在應(yīng)對(duì)家具挪動(dòng)這類(lèi)頻繁摩擦?xí)r，更厚的耐磨層能極大程度降低磨損程度，長(zhǎng)久保持地板美觀。像我曾走訪(fǎng)的一戶(hù)家庭，客廳安裝了厚耐磨層石晶地板，使用 5 年后，地板除了因光照有些許褪色外，表面幾乎沒(méi)有因日常走動(dòng)、孩子玩耍造成的明顯劃痕，依舊光潔如新，而鄰居家使用普通厚度耐磨層地板，不到 3 年劃痕就已遍布，視覺(jué)效果大打折扣。
耐用性方面，同樣有令人信服的數(shù)據(jù)支撐。在加速老化實(shí)驗(yàn)中，模擬商業(yè)場(chǎng)所高強(qiáng)度使用，讓地板經(jīng)受持續(xù)的踩踏、重物拖拉。一組耐磨層 0.4mm 的石晶地板，在相當(dāng)于正常使用 3 年的模擬時(shí)長(zhǎng)后，耐磨層出現(xiàn)局部磨穿現(xiàn)象，基材開(kāi)始暴露，地板結(jié)構(gòu)穩(wěn)定性受到影響，出現(xiàn)輕微變形；而另一組耐磨層 0.8mm 的石晶地板，經(jīng)過(guò)長(zhǎng)達(dá) 8 年的等效模擬使用，耐磨層雖有一定程度磨損，但依然完整地保護(hù)著基材，地板整體結(jié)構(gòu)穩(wěn)固，沒(méi)有出現(xiàn)變形、開(kāi)裂等問(wèn)題。某大型商場(chǎng)在翻新時(shí)選擇了我們厚耐磨層石晶地板，日均客流量數(shù)千人次，使用 4 年后，地板磨損微小，未出現(xiàn)因頻繁踩踏導(dǎo)致的嚴(yán)重?fù)p耗，大大降低了維護(hù)成本，若換做普通耐磨層地板，恐怕早已傷痕累累，需要大面積更換。
抗污表現(xiàn)上，厚耐磨層的優(yōu)勢(shì)同樣突出。我們將等量的油污分別倒在 0.35mm 和 0.7mm 耐磨層的石晶地板樣板上，靜置 30 分鐘后擦拭。0.35mm 耐磨層的地板，油污滲入了一定深度，擦拭后仍殘留淡淡的污漬痕跡；而 0.7mm 耐磨層的地板，油污基本停留在表面，用濕布輕輕一擦就干干凈凈，表面毫無(wú)殘留。曾有一家餐廳反饋，之前鋪設(shè)的普通石晶地板，廚房區(qū)域經(jīng)常有油污沾染，時(shí)間一久，污漬滲入，怎么清潔都有印子，后來(lái)?yè)Q成厚耐磨層石晶地板，即使偶爾有大面積油污潑濺，及時(shí)清理后也不會(huì)留下難看的污漬，日常打理輕松許多。
防滑性能測(cè)試中，厚耐磨層的作用也不容小覷。利用專(zhuān)業(yè)的摩擦系數(shù)測(cè)試儀，對(duì) 0.4mm 和 0.8mm 耐磨層石晶地板在干燥、潮濕環(huán)境下分別測(cè)量。干燥時(shí)，0.4mm 耐磨層地板摩擦系數(shù)為 0.5，0.8mm 耐磨層地板可達(dá) 0.65；潮濕環(huán)境下，差距更為明顯，前者摩擦系數(shù)降至 0.35，后者仍能維持在 0.5 左右。在一個(gè)社區(qū)老年活動(dòng)中心的衛(wèi)生間，原本使用的普通地板，每逢雨后潮濕時(shí)，老人滑倒事故時(shí)有發(fā)生，更換為厚耐磨層石晶地板后，因防滑性能提升，滑倒現(xiàn)象大幅減少，為老人提供了更安全的活動(dòng)空間。
在工廠(chǎng)生產(chǎn)環(huán)節(jié)，為保障厚耐磨層的卓越品質(zhì)，我們從原材料篩選就嚴(yán)格把關(guān)，選用高強(qiáng)度、高耐磨的高分子材料，確保耐磨層的致密性。生產(chǎn)過(guò)程中，運(yùn)用精密的涂布工藝，使耐磨層厚度均勻，誤差控制在極小范圍內(nèi)。每一批次產(chǎn)品出廠(chǎng)前，都要經(jīng)過(guò)多輪嚴(yán)格檢測(cè)，模擬各種真實(shí)使用場(chǎng)景測(cè)試性能，只為向市場(chǎng)輸送高品質(zhì)、厚耐磨層的石晶地板。
總之，石晶地板的耐磨層厚度直接關(guān)聯(lián)其耐磨性、耐用性、抗污性與防滑性能，越厚越能在多樣復(fù)雜的環(huán)境下表現(xiàn)出色，延長(zhǎng)使用壽命。作為技術(shù)員，我將和團(tuán)隊(duì)持續(xù)精進(jìn)，為消費(fèi)者打造更優(yōu)質(zhì)的石晶地板，讓家居、商用環(huán)境都能因它而更美好。
As a technician in a flooring factory, I have deeply realized the key significance of the thickness of the wear-resistant layer for stone crystal floors in the process of long-term research on stone crystal floors. It is no exaggeration to say that the thicker the wear-resistant layer, the better.
Let's talk about the significant differences in daily wear scenarios first. We have done tests in a laboratory that simulates the use environment of a family living room. We selected two
spc flooring, one with a wear-resistant layer thickness of 0.3mm and the other with a thickness of 0.6mm. After the same 100,000 simulated frictions of moving tables and chairs, the surface of the floor with a 0.3mm wear-resistant layer showed obvious fine scratches. When you look closely, the scratches are densely distributed, and you can clearly feel the unevenness by touching it with your hands; on the other hand, the floor with a 0.6mm wear-resistant layer has only a few very shallow scratches, which hardly affects the visual perception, and the surface of the floor is still smooth and flat. This clearly shows that when dealing with frequent friction such as furniture movement, a thicker wear-resistant layer can greatly reduce the degree of wear and keep the floor beautiful for a long time. For example, a family I visited installed a stone crystal floor with a thick wear-resistant layer in the living room. After 5 years of use, the floor has almost no obvious scratches caused by daily walking and children playing, except for some fading due to light. The surface is still as bright and clean as new. However, the neighbor's family uses a floor with a normal wear-resistant layer, and scratches have been everywhere in less than 3 years, greatly reducing the visual effect.
In terms of durability, there is also convincing data support. In the accelerated aging experiment, the high-intensity use of commercial places is simulated, and the floor is subjected to continuous trampling and heavy dragging. A group of stone crystal floors with a wear-resistant layer of 0.4mm, after a simulation time equivalent to 3 years of normal use, the wear-resistant layer was partially worn out, the substrate began to be exposed, the stability of the floor structure was affected, and slight deformation occurred; while another group of stone crystal floors with a wear-resistant layer of 0.8mm, after 8 years of equivalent simulated use, although the wear-resistant layer was worn to a certain extent, it still completely protected the substrate, and the overall structure of the floor was stable, without deformation, cracking and other problems. A large shopping mall chose our thick wear-resistant layer stone crystal floor during renovation. The average daily passenger flow is thousands of people. After 4 years of use, the floor is slightly worn and there is no serious loss caused by frequent trampling, which greatly reduces the maintenance cost. If it is replaced with an ordinary wear-resistant floor, it may have been scarred and need to be replaced on a large scale.
In terms of anti-fouling performance, the advantages of thick wear-resistant layer are also outstanding. We poured the same amount of oil on the stone crystal floor samples with 0.35mm and 0.7mm wear-resistant layers, respectively, and wiped them after standing for 30 minutes. For the floor with 0.35mm wear-resistant layer, the oil penetrated to a certain depth, and there were still faint stains after wiping; while for the floor with 0.7mm wear-resistant layer, the oil basically stayed on the surface, and it was cleaned with a damp cloth, and there was no residue on the surface. A restaurant once reported that the kitchen area of ??the ordinary stone crystal floor that was previously laid was often stained with oil. After a long time, the stains penetrated and left marks no matter how they were cleaned. Later, they were replaced with stone crystal floors with thick wear-resistant layers. Even if there were occasional large-scale oil splashes, they would not leave ugly stains after timely cleaning, making daily maintenance much easier.
In the anti-slip performance test, the role of the thick wear-resistant layer should not be underestimated. Using a professional friction coefficient tester, the 0.4mm and 0.8mm wear-resistant layer stone crystal floors were measured in dry and wet environments. When dry, the friction coefficient of the 0.4mm wear-resistant layer floor is 0.5, and the 0.8mm wear-resistant layer floor can reach 0.65; in a wet environment, the difference is more obvious, the friction coefficient of the former drops to 0.35, and the latter can still maintain around 0.5. In the bathroom of a community elderly activity center, the ordinary floor used originally, when it was wet after rain, the elderly often slipped. After replacing it with a thick wear-resistant layer of stone crystal floor, the anti-slip performance was improved, and the slip phenomenon was greatly reduced, providing a safer activity space for the elderly.
In the factory production process, in order to ensure the excellent quality of the thick wear-resistant layer, we strictly control the selection of raw materials, select high-strength and high-wear-resistant polymer materials to ensure the density of the wear-resistant layer. During the production process, a precise coating process is used to make the thickness of the wear-resistant layer uniform and the error is controlled within a very small range. Before each batch of products leaves the factory, it must undergo multiple rounds of rigorous testing to simulate various real-life usage scenarios to test the performance, just to deliver high-quality, thick wear-resistant layer of stone crystal flooring to the market.
In short, the thickness of the wear-resistant layer of the stone crystal floor is directly related to its wear resistance, durability, stain resistance and anti-slip performance. The thicker it is, the better it can perform in a variety of complex environments and extend its service life. As a technician, I will continue to improve with my team to create better quality stone crystal floors for consumers, so that home and commercial environments can be better because of it.
