pvc地板施工(gong)過程中不(bu)容(rong)忽視的重要因素

一是基層面的強度

如果基(ji)層(ceng)面強(qiang)度(du)不符(fu)合(he)要求或太(tai)低(di)，環氧樹脂涂(tu)膜固化后(hou)會(hui)拉(la)開(kai)砂漿面造成剝離而現場(chang)可(ke)(ke)用(yong)鋼絲(si)刷摩擦，也可(ke)(ke)以(yi)用(yong)回彈(dan)儀作混(hun)凝(ning)土(tu)(tu)強(qiang)度(du)測試混(hun)凝(ning)土(tu)(tu)基(ji)層(ceng)面，或用(yong)小鐵(tie)錘敲(qiao)打基(ji)層(ceng)面來判定(ding)，也可(ke)(ke)現場(chang)做粘結強(qiang)度(du)（大于(yu)1MPa為宜(yi))試驗；

二是基層(ceng)面的干燥程度

因(yin)混(hun)凝土和砂漿(jiang)找(zhao)平(ping)面施工過程中(zhong)含有大量(liang)水分，待地面涂料施工時必須干燥到所要求的程度，現場可以以基(ji)層(ceng)施工后的養護時間來(lai)簡單判定表(biao)面是否發白(bai)或測含水率(lv)(必須基(ji)于基(ji)層(ceng)已(yi)做防潮、防水層(ceng)處理)；

三是“平坦性(xing)”

即基層面上(shang)沒有不規(gui)則、凹凸不平(ping)之(zhi)現象，涂(tu)膜與砂漿層相(xiang)(xiang)比(bi)相(xiang)(xiang)當薄(bo)、基層面的平(ping)坦(tan)度直(zhi)接會影響涂(tu)膜的整體表觀質量，現場(chang)可(ke)用(yong)長2米(mi)直(zhi)尺貼在基層面上(shang)，看所(suo)出現的縫(feng)隙(xi)在5mm以內(nei)來作為基層面平(ping)坦(tan)測(ce)定的方法，對要求更高的自流平(ping)涂(tu)料來講地面盡量做到(dao)2米(mi)直(zhi)尺縫(feng)隙(xi)在3毫米(mi)以內(nei)，施工(gong)時可(ke)借助機械打磨(mo)機進行進一步(bu)的局部(bu)“找平(ping)”；

四是基層面的平滑性(xing)

平滑度(du)(du)即基(ji)(ji)層(ceng)面(mian)用(yong)金屬抹子涂抹得(de)平滑，沒有粗(cu)糙(cao)(cao)的(de)毛面(mian)也是會(hui)影(ying)響成(cheng)膜物與基(ji)(ji)層(ceng)之間(jian)粘結(jie)力(li)，如(ru)果基(ji)(ji)層(ceng)面(mian)特別粗(cu)糙(cao)(cao)一(yi)則可能(neng)基(ji)(ji)層(ceng)強度(du)(du)不足、二則消耗大量材(cai)料，所以合適的(de)粗(cu)糙(cao)(cao)度(du)(du)對地面(mian)涂層(ceng)是很關鍵的(de)因(yin)素，現(xian)場多(duo)用(yong)輕度(du)(du)噴砂(丸)機(ji)進(jin)行(xing)表面(mian)處理并吸去(qu)浮塵。

五是(shi)焊接(jie)工(gong)藝

把(ba)(ba)地(di)(di)(di)(di)板(ban)(ban)(ban)之間的(de)(de)(de)(de)縫(feng)隙清潔(jie)干(gan)凈。（包括膠(jiao)水、油污）把(ba)(ba)焊(han)(han)(han)(han)絲(si)根(gen)據(ju)地(di)(di)(di)(di)板(ban)(ban)(ban)的(de)(de)(de)(de)縫(feng)隙進(jin)行(xing)(xing)裁量。用(yong)(yong)美(mei)(mei)工(gong)刀或(huo)開槽三角(jiao)(jiao)刀把(ba)(ba)要(yao)(yao)焊(han)(han)(han)(han)接(jie)(jie)(jie)的(de)(de)(de)(de)縫(feng)隙兩邊(bian)(bian)進(jin)行(xing)(xing)開槽或(huo)拉毛(mao)（主要(yao)(yao)為了把(ba)(ba)焊(han)(han)(han)(han)絲(si)順利溶化(hua)(hua)到(dao)地(di)(di)(di)(di)板(ban)(ban)(ban)縫(feng)隙中去）。調好焊(han)(han)(han)(han)槍上的(de)(de)(de)(de)溫度(du)，把(ba)(ba)焊(han)(han)(han)(han)絲(si)溶化(hua)(hua)在地(di)(di)(di)(di)板(ban)(ban)(ban)的(de)(de)(de)(de)縫(feng)隙中，首(shou)先用(yong)(yong)美(mei)(mei)工(gong)刀沿著(zhu)地(di)(di)(di)(di)板(ban)(ban)(ban)的(de)(de)(de)(de)平(ping)(ping)面向(xiang)同(tong)一(yi)方向(xiang)推進(jin)進(jin)行(xing)(xing)修整(zheng)。然后(hou)當接(jie)(jie)(jie)合處全冷(leng)卻后(hou)，再用(yong)(yong)美(mei)(mei)工(gong)刀進(jin)行(xing)(xing)第二次休整(zheng)，以確(que)保焊(han)(han)(han)(han)條(tiao)與(yu)地(di)(di)(di)(di)板(ban)(ban)(ban)材料齊平(ping)(ping)。把(ba)(ba)超(chao)過地(di)(di)(di)(di)板(ban)(ban)(ban)平(ping)(ping)面的(de)(de)(de)(de)焊(han)(han)(han)(han)絲(si)割平(ping)(ping)。折角(jiao)(jiao)處：用(yong)(yong)焊(han)(han)(han)(han)槍將(jiang)地(di)(di)(di)(di)板(ban)(ban)(ban)在折角(jiao)(jiao)處烘軟后(hou)再卷(juan)邊(bian)(bian)。（卷(juan)邊(bian)(bian)出要(yao)(yao)安(an)裝帶焊(han)(han)(han)(han)接(jie)(jie)(jie)接(jie)(jie)(jie)頭的(de)(de)(de)(de)凹圓踢角(jiao)(jiao)線）注(zhu)意(yi)事項：施工(gong)完畢后(hou)在10天(tian)內不能用(yong)(yong)大(da)量的(de)(de)(de)(de)水去清潔(jie)地(di)(di)(di)(di)面，因膠(jiao)水全固化(hua)(hua)需要(yao)(yao)10天(tian)左右時間，如果這時用(yong)(yong)大(da)量水去清潔(jie)地(di)(di)(di)(di)面，水會從縫(feng)隙中滲進(jin)去，破壞膠(jiao)水的(de)(de)(de)(de)粘接(jie)(jie)(jie)強度(du)，（焊(han)(han)(han)(han)接(jie)(jie)(jie)好的(de)(de)(de)(de)卷(juan)材地(di)(di)(di)(di)板(ban)(ban)(ban)除外）膠(jiao)水涂刮(gua)后(hou)，必(bi)須在3-6小時內貼完。
