1 水性環氧地坪
嚴格地(di)(di)講,水(shui)性(xing)環(huan)(huan)氧(yang)地(di)(di)坪(ping)(ping)涂(tu)料(liao)不能(neng)算作真正意(yi)義的(de)功(gong)能(neng)性(xing)地(di)(di)坪(ping)(ping)涂(tu)料(liao),但是(shi)由于其全部采用(yong)不含溶劑的(de)水(shui)性(xing)環(huan)(huan)氧(yang)樹脂(zhi)做材料(liao),無(wu)毒、無(wu)味(wei),涂(tu)裝過程中(zhong)亦無(wu)污染(ran),環(huan)(huan)境友好(hao);涂(tu)層美觀(guan)、易清(qing)潔,防(fang)水(shui)防(fang)潮;同時還可根據(ju)需(xu)要上水(shui)性(xing)環(huan)(huan)氧(yang)罩面(mian)清(qing)漆,可獲得更高光澤的(de)水(shui)性(xing)環(huan)(huan)氧(yang)地(di)(di)坪(ping)(ping)。
水(shui)(shui)性(xing)環(huan)氧地坪(ping)涂料(liao)特(te)別適用(yong)于(yu)食品廠、制藥廠車間以及倉庫等場(chang)所,漆膜無毒,涂裝(zhuang)過程中對食品及藥品等無污(wu)染,同時(shi)也(ye)特(te)別適用(yong)于(yu)潮濕地面涂裝(zhuang)。中遠關西涂料(liao)公司開發出了新型水(shui)(shui)性(xing)環(huan)氧地坪(ping)涂料(liao),其具有優異的保(bao)光保(bao)色(se)性(xing)和突出的耐(nai)候性(xing),可以極低的厚度(du)( 500 m m 以內(nei))實(shi)現傳統無溶劑地坪(ping)涂料(liao)數毫米(mi)的性(xing)能,填補(bu)了我國(guo)國(guo)內(nei)市場(chang)的空白。
2 彩色耐磨整體藝術地坪
彩(cai)色(se)(se)耐磨(mo)整(zheng)體(ti)藝(yi)術(shu)(shu)地(di)(di)(di)坪是(shi)一種近年來流行于美國、加拿大(da)、澳大(da)利(li)亞、歐洲并在世界主(zhu)要發達國家,且(qie)得到迅速推廣的綠色(se)(se)環(huan)保地(di)(di)(di)面(mian)(mian)(mian)裝飾鋪面(mian)(mian)(mian)材(cai)料。它(ta)能在原本普通的新舊混(hun)凝土(tu)(tu)表層創造出(chu)各(ge)(ge)種天然大(da)理石(shi)、花崗巖、磚(zhuan)、瓦、木(mu)地(di)(di)(di)板等(deng)鋪設效果,具有圖(tu)形美觀自(zi)然、色(se)(se)彩(cai)真實持久(jiu)、質地(di)(di)(di)堅固耐用等(deng)特點(dian),可根(gen)據業主(zhu)的要求(qiu),設計(ji)出(chu)各(ge)(ge)種彩(cai)色(se)(se)平面(mian)(mian)(mian)圖(tu)案。它(ta)的誕生從(cong)根(gen)本上克服了(le)傳統磚(zhuan)、石(shi)鋪設地(di)(di)(di)面(mian)(mian)(mian)常(chang)(chang)有的容易松動、凹凸不(bu)平、縫隙長草、蟲蟻筑穴、容易起塵、路面(mian)(mian)(mian)整(zheng)體(ti)性(xing)差、施工周期長、需(xu)經常(chang)(chang)維修等(deng)缺點(dian)。彩(cai)色(se)(se)耐磨(mo)整(zheng)體(ti)藝(yi)術(shu)(shu)地(di)(di)(di)坪結合(he)了(le)傳統磚(zhuan)、石(shi)鋪設地(di)(di)(di)面(mian)(mian)(mian)的美觀自(zi)然與混(hun)凝土(tu)(tu)的堅固耐用特點(dian),是(shi)替代(dai)磚(zhuan)、石(shi)鋪設地(di)(di)(di)面(mian)(mian)(mian)的一種理想的新型地(di)(di)(di)面(mian)(mian)(mian)裝飾材(cai)料。
