地坪漆按功能分類 地坪漆的用途分類
1.按功能和用途分類
(1)裝飾性地坪漆
以美(mei)化、裝(zhuang)飾為主要作用(yong)的地(di)坪(ping)漆,具有防(fang)滲、防(fang)塵(chen)、便(bian)于(yu)消毒(du)和清潔等功能(neng)。常見品種有溶劑型環氧涂(tu)料、溶劑型聚氨酯涂(tu)料、環氧彩砂彩石涂(tu)料、亞克力涂(tu)料等。用(yong)于(yu)展館展廳、商場(chang)超市、候機樓(lou)、大堂、公(gong)(gong)園等公(gong)(gong)共場(chang)所(suo)和商業場(chang)所(suo),也(ye)用(yong)于(yu)輕載(zai)工業廠房地(di)坪(ping)。
(2)耐重載地坪漆
普通混凝土的抗沖(chong)擊和(he)耐磨損性(xing)能較(jiao)差,表面破損后又不易修補(bu),所以常選擇(ze)使(shi)用壓(ya)砂、砂漿等力(li)學性(xing)能較(jiao)高的地坪漆作保護層,增加地坪表面抗沖(chong)擊性(xing)能和(he)承載能力(li)。用于(yu)重型機(ji)械制造(zao)、飛機(ji)機(ji)庫、汽車(che)制造(zao)、汽車(che)修理等行業。
(3)重防腐地坪漆
用于接(jie)觸酸、堿、鹽等(deng)化(hua)學腐蝕(shi)性藥品的地面,可以有(you)效保護水泥地板,防(fang)止化(hua)學介質侵入對水泥地面造(zao)成的腐蝕(shi)。有(you)乙烯(xi)基酯重防(fang)腐地坪(ping)漆,聚氨酯、酚(fen)醛環氧、乙烯(xi)基樹脂等(deng)涂料品種。常用于電鍍、化(hua)工、造(zao)紙、食品制(zhi)造(zao)等(deng)行業。
(4)防靜電地坪漆
提供地(di)坪抗(kang)靜(jing)(jing)(jing)電(dian)(dian)功能,表(biao)面電(dian)(dian)阻為(wei)2.5×l04~1.0×l09Ω,可有(you)效泄露(lu)靜(jing)(jing)(jing)電(dian)(dian)荷,消除靜(jing)(jing)(jing)電(dian)(dian)積累和(he)電(dian)(dian)磁干擾(rao)的(de)(de)(de)危害。按美國(guo)材(cai)料和(he)試驗(yan)協會(hui)標準(ASTM),防靜(jing)(jing)(jing)電(dian)(dian)地(di)板(ban)分為(wei)三(san)種,即導(dao)(dao)(dao)(dao)靜(jing)(jing)(jing)電(dian)(dian)地(di)板(ban)(ECF,其表(biao)面電(dian)(dian)阻為(wei)2.5×l04~1.0×106Ω);靜(jing)(jing)(jing)電(dian)(dian)耗散型(xing)地(di)板(ban)(DIF,其表(biao)面電(dian)(dian)阻為(wei)1.0×l06~1.0×l09Ω)和(he)難起靜(jing)(jing)(jing)電(dian)(dian)地(di)板(ban)(ASF,其表(biao)面電(dian)(dian)阻為(wei)1.0×l06~1.0×109Ω)。國(guo)內常用(yong)的(de)(de)(de)涂料品種有(you)以(yi)導(dao)(dao)(dao)(dao)電(dian)(dian)包核云母粉、導(dao)(dao)(dao)(dao)電(dian)(dian)氧化(hua)鋅等(deng)導(dao)(dao)(dao)(dao)電(dian)(dian)填料為(wei)導(dao)(dao)(dao)(dao)電(dian)(dian)介質的(de)(de)(de)溶(rong)劑(ji)型(xing)防靜(jing)(jing)(jing)電(dian)(dian)地(di)坪漆和(he)無溶(rong)劑(ji)環氧防靜(jing)(jing)(jing)電(dian)(dian)自(zi)流(liu)平地(di)坪漆,以(yi)及以(yi)導(dao)(dao)(dao)(dao)電(dian)(dian)纖維作(zuo)導(dao)(dao)(dao)(dao)電(dian)(dian)介質的(de)(de)(de)無溶(rong)劑(ji)環氧導(dao)(dao)(dao)(dao)靜(jing)(jing)(jing)電(dian)(dian)自(zi)流(liu)平地(di)坪漆。已廣泛應用(yong)于電(dian)(dian)子(zi)、精密儀器(qi)、粉體(ti)制造、軍工生(sheng)產等(deng)領(ling)域需要防靜(jing)(jing)(jing)電(dian)(dian)的(de)(de)(de)場所。
(5)彈性(防滑)地坪漆
玻(bo)璃化溫度(du)低于(yu)室溫,斷裂伸長(chang)率大于(yu)50%,取消外力作用后涂層具有較好復原性(xing)能的地坪漆(qi)。
(6)耐高溫等特殊功能
地(di)(di)坪漆(qi)提供地(di)(di)坪特(te)(te)殊功能(neng)性,使用前需做相關(guan)性能(neng)的檢測(ce)。常(chang)見品種有用碎木屑等制作的抗(kang)沖(chong)擊火花地(di)(di)坪漆(qi),以及(ji)聚氨酯耐高溫地(di)(di)坪漆(qi)等。用于易燃易爆危臉(lian)品制造等特(te)(te)殊場(chang)合對上述(shu)性能(neng)有相應要求的地(di)(di)面(mian)。
