发布日期:2019/12/10

因(yin)天气(qi)逐渐转冷,进入霜冻(dong)(dong)季节,这种天气(qi)情况下,应(ying)注(zhu)意涂料(liao)(liao)产品施工(gong)天气(qi)及(ji)气(qi)温(wen)的(de)条件,如水(shui)性(xing)(xing)涂料(liao)(liao)受冻(dong)(dong)后,涂料(liao)(liao)中(zhong)的(de)乳液会(hui)难(nan)以成膜甚(shen)至破乳而失去功效,造(zao)成耐水(shui)性(xing)(xing)差,严重(zhong)的(de)会(hui)起粉甚(shen)至脱落,施工(gong)质量(liang)将无法得(de)到保证。故(gu)我司建议冬季涂料(liao)(liao)施工(gong)应(ying)注(zhu)意以下几点:

1、涂料的(de)储存:

待用的(de)(de)涂料产品应放(fang)置在至少(shao)0℃以上的(de)(de)仓库或有保温设施(shi)的(de)(de)房(fang)间里。

2、施工的天气与气温:

(1)施(shi)工(gong)(gong)时应注(zhu)意气温的(de)变化。涂料的(de)施(shi)工(gong)(gong)和(he)干燥(zao)(zao)成(cheng)膜过程应在5℃以上(shang),湿度小于(yu)80%,冬季施(shi)工(gong)(gong)时间(jian)控(kong)制在上(shang)午(wu)10点到(dao)下午(wu)3点之间(jian)。一(yi)般施(shi)工(gong)(gong)干燥(zao)(zao)应控(kong)制在6小时左右,请把握(wo)好(hao)干燥(zao)(zao)时间(jian)的(de)控(kong)制,施(shi)工(gong)(gong)和(he)干燥(zao)(zao)成(cheng)膜过程中(zhong),注(zhu)意防(fang)止(zhi)雨水(shui)侵蚀。

(2)应充(chong)分了解(jie)当地的天气(qi)情况(kuang),避(bi)免雨雪霜冻天气(qi)施(shi)工(gong),且应避(bi)免涂料在施(shi)工(gong)后6小(xiao)时内遭(zao)遇类(lei)似气(qi)象(xiang)条件。

3、基层(ceng)的养护与要(yao)求:

   冬季施工(gong)(gong)应保持底材的彻底干(gan)燥(zao),外墙施工(gong)(gong)时注意腻子的养护时间和施工(gong)(gong)工(gong)(gong)艺。

腻子层要(yao)求冲(chong)水(shui)养(yang)护1~2遍,pH值小(xiao)于(yu)10,含水(shui)率(lv)小(xiao)于(yu)10%,再进行(xing)底(di)漆施工,底(di)漆须彻底(di)干燥进行(xing)下道工序的施工。

4、厚(hou)质类(lei)涂料(真石漆、质感涂料、水性多彩)的施工:

(1)厚(hou)质类(lei)涂(tu)料在低温条件(jian)下(xia)(xia)施工(gong)(gong)(gong)(gong),一次性厚(hou)膜(mo)(mo)施工(gong)(gong)(gong)(gong),易引起(qi)涂(tu)膜(mo)(mo)成膜(mo)(mo)较慢影(ying)响漆(qi)膜(mo)(mo)性能等质量问题。为避(bi)免此类(lei)问题的出现,冬(dong)季(ji)施工(gong)(gong)(gong)(gong)时,尽量按照(zhao)薄喷(pen)两遍(bian)(bian)的施工(gong)(gong)(gong)(gong)方案进行(xing)(xing)施工(gong)(gong)(gong)(gong)。待实干后,方可进行(xing)(xing)下(xia)(xia)一遍(bian)(bian)的施工(gong)(gong)(gong)(gong),保(bao)证漆(qi)膜(mo)(mo)正(zheng)常的干燥成膜(mo)(mo)。

(2)施工时应尽量控制同一墙(qiang)(qiang)面(mian)(mian)(mian)(mian)使(shi)用同一批次材(cai)料(liao)施工,避免同一墙(qiang)(qiang)面(mian)(mian)(mian)(mian)施工多(duo)批材(cai)料(liao)。如若不可避免有两(liang)批次材(cai)料(liao)施工在同一墙(qiang)(qiang)面(mian)(mian)(mian)(mian),请尽量将少量批次的材(cai)料(liao)安排(pai)在背面(mian)(mian)(mian)(mian)或凹凸面(mian)(mian)(mian)(mian)的墙(qiang)(qiang)面(mian)(mian)(mian)(mian)为(wei)宜。

5、911环保型(xing)聚氨酯(zhi)防水涂(tu)料的(de)施(shi)工:

   911环保型(xing)聚氨酯防(fang)水涂料(liao)(liao)由甲、乙(yi)组(zu)份配(pei)(pei)套组(zu)成,聚氨酯材料(liao)(liao)粘(zhan)(zhan)度受温(wen)(wen)度影(ying)响(xiang)比较大,到冬季由于气温(wen)(wen)降(jiang)低,材料(liao)(liao)粘(zhan)(zhan)度就会变(bian)大,我们生(sheng)产时(shi)(shi)已经(jing)采用冬季配(pei)(pei)方来(lai)改(gai)善(shan)施(shi)工(gong)(gong)性(xing)。建议现(xian)(xian)场施(shi)工(gong)(gong)时(shi)(shi)严(yan)禁添加其它(ta)稀释(shi)剂,因为过多添加稀释(shi)剂会改(gai)变(bian)甲、乙(yi)之间配(pei)(pei)比,破坏(huai)材料(liao)(liao)固化机理,导致施(shi)工(gong)(gong)后(hou)涂膜(mo)不干和粘(zhan)(zhan)手等(deng)现(xian)(xian)象,影(ying)响(xiang)防(fang)水涂料(liao)(liao)成膜(mo),降(jiang)低防(fang)水性(xing)能和工(gong)(gong)程质量。
