P V C 地(di) 板 施(shi) 工

　　本工程設計采用PVC卷(juan)材地板，自流(liu)平基層。本工藝控制重點(dian)為自流(liu)平除氣(水氣和空氣)和PVC卷(juan)材地板平整(zheng)度及無縫焊接(jie)。

　　自(zi)(zi)流(liu)(liu)平：自(zi)(zi)流(liu)(liu)平漿(jiang)料傾(qing)倒入地坪，任(ren)其(qi)像(xiang)水一樣流(liu)(liu)平開來(lai)進行自(zi)(zi)動找平，必須使(shi)用專(zhuan)用齒口(kou)自(zi)(zi)流(liu)(liu)平子母刮板加以(yi)來(lai)回橫向、豎向疏導。

　　在自流平(ping)(ping)初凝前須穿釘鞋走(zou)入(ru)自流平(ping)(ping)地面(mian)，用專(zhuan)用放氣滾(gun)筒滾(gun)扎地面(mian)以(yi)排除因混合(he)時帶(dai)入(ru)的(de)空(kong)氣，避免氣泡，麻面(mian)及接口高差。養護1—2天即可(ke)鋪設。

　　PVC卷材地(di)(di)(di)(di)(di)(di)(di)(di)板平(ping)整度：PVC地(di)(di)(di)(di)(di)(di)(di)(di)板正(zheng)(zheng)確(que)的存(cun)放(fang)方(fang)法(fa)為豎直存(cun)放(fang)，不正(zheng)(zheng)確(que)的儲存(cun)方(fang)法(fa)會導致PVC地(di)(di)(di)(di)(di)(di)(di)(di)板鋪貼(tie)時形成(cheng)波浪型，且(qie)容易使PVC地(di)(di)(di)(di)(di)(di)(di)(di)板邊部損傷，影響安裝(zhuang)效果。把切割好的PVC地(di)(di)(di)(di)(di)(di)(di)(di)板平(ping)放(fang)在地(di)(di)(di)(di)(di)(di)(di)(di)面上，仔細檢查(cha)PVC地(di)(di)(di)(di)(di)(di)(di)(di)板表面，防止出(chu)現質量問題。PVC地(di)(di)(di)(di)(di)(di)(di)(di)板與(yu)PVC地(di)(di)(di)(di)(di)(di)(di)(di)板之間(jian)(jian)不應預留任何空(kong)間(jian)(jian)。鋪貼(tie)完一個空(kong)間(jian)(jian)，膠水未完全干(gan)固前，再用(yong)大鐵磙推壓地(di)(di)(di)(di)(di)(di)(di)(di)面，使已貼(tie)好的地(di)(di)(di)(di)(di)(di)(di)(di)板更加平(ping)整，或用(yong)沙袋壓實。

　　PVC地板(ban)(ban)熱(re)力焊(han)(han)(han)接：熱(re)力焊(han)(han)(han)接是連接PVC地板(ban)(ban)接縫(feng)的最佳方法。熱(re)力焊(han)(han)(han)接應在鋪(pu)貼PVC地板(ban)(ban)工作完(wan)(wan)成24小時后(hou)進行。用(yong)專業(ye)開(kai)槽刀(dao)(dao)或(huo)專業(ye)自(zi)動(dong)開(kai)槽機(ji)在地板(ban)(ban)接縫(feng)處(chu)開(kai)出“U”型焊(han)(han)(han)槽。槽的深度約為地材的三(san)分(fen)之(zhi)二，但(dan)不可(ke)超過2mm。用(yong)專業(ye)焊(han)(han)(han)機(ji)把(ba)地材專用(yong)焊(han)(han)(han)線(xian)焊(han)(han)(han)接在“U”型槽內(nei)。待焊(han)(han)(han)條(tiao)溫度略降時，用(yong)專用(yong)鏟(chan)刀(dao)(dao)把(ba)焊(han)(han)(han)線(xian)剩余凸起(qi)部分(fen)鏟(chan)掉三(san)分(fen)之(zhi)二，當焊(han)(han)(han)線(xian)完(wan)(wan)全冷卻后(hou)，再用(yong)鏟(chan)刀(dao)(dao)把(ba)焊(han)(han)(han)線(xian)剩余凸起(qi)部分(fen)完(wan)(wan)全鏟(chan)掉。焊(han)(han)(han)線(xian)一定要分(fen)兩次(ci)鏟(chan)除(chu)
