廠區道路劃線分為(wei):熱熔(rong)標(biao)(biao)線(xian)(xian)，常溫冷漆標(biao)(biao)線(xian)(xian)，彩色(se)防滑(hua)標(biao)(biao)線(xian)(xian)，振蕩防滑(hua)反(fan)光(guang)標(biao)(biao)線(xian)(xian)和(he)預成型標(biao)(biao)線(xian)(xian)。 熱熔(rong)標(biao)(biao)線(xian)(xian)是我國道(dao)路標(biao)(biao)線(xian)(xian)上應(ying)用最廣的一種標(biao)(biao)線(xian)(xian)。他施(shi)工時間短，耐磨性高，造價低。 道(dao)路交通標(biao)(biao)線(xian)(xian)主要劃設于道(dao)路表(biao)面，經受(shou)日曬雨淋，風雪冰凍(dong)，遭受(shou)車(che)輛的沖(chong)擊(ji)磨耗(hao)，因(yin)此(ci)對其性能有(you)嚴(yan)格的要求。首先要求干(gan)燥時間短，操作簡單，以減少交通干(gan)擾；其次(ci)要求反(fan)射能力(li)強，色(se)彩鮮明，反(fan)光(guang)度(du)強，使(shi)白天、夜晚都有(you)良好的能見(jian)度(du)；第三，應(ying)具(ju)有(you)抗(kang)滑(hua)性和(he)耐磨性，以保證行(xing)車(che)安全和(he)使(shi)用壽命(ming)。

根(gen)據圖樣和技(ji)術(shu)要(yao)(yao)求，在(zai)(zai)毛(mao)坯或半(ban)成品上(shang)用劃(hua)(hua)線(xian)(xian)(xian)工(gong)(gong)(gong)具畫出(chu)加(jia)(jia)工(gong)(gong)(gong)界(jie)線(xian)(xian)(xian)，或劃(hua)(hua)出(chu)作(zuo)為(wei)(wei)基準(zhun)的點、線(xian)(xian)(xian)的操作(zuo)過程稱為(wei)(wei)劃(hua)(hua)線(xian)(xian)(xian)。劃(hua)(hua)線(xian)(xian)(xian)分為(wei)(wei)平面劃(hua)(hua)線(xian)(xian)(xian)和立體劃(hua)(hua)線(xian)(xian)(xian)兩種。只需要(yao)(yao)在(zai)(zai)工(gong)(gong)(gong)件一個表(biao)面上(shang)劃(hua)(hua)線(xian)(xian)(xian)即能明確表(biao)明加(jia)(jia)工(gong)(gong)(gong)界(jie)限的，稱之(zhi)為(wei)(wei)平面劃(hua)(hua)線(xian)(xian)(xian)；需要(yao)(yao)在(zai)(zai)工(gong)(gong)(gong)件幾(ji)個互成不同角度（一般是互相垂直）的表(biao)面上(shang)劃(hua)(hua)線(xian)(xian)(xian)，才(cai)能明確表(biao)明加(jia)(jia)工(gong)(gong)(gong)界(jie)限的，稱為(wei)(wei)立體劃(hua)(hua)線(xian)(xian)(xian)。對劃(hua)(hua)線(xian)(xian)(xian)的基本要(yao)(yao)求是線(xian)(xian)(xian)條清晰勻稱，定(ding)型、定(ding)位尺寸(cun)準(zhun)確。由于劃(hua)(hua)線(xian)(xian)(xian)的線(xian)(xian)(xian)條有一定(ding)寬度，一般要(yao)(yao)求精度達(da)到0.25-0.5mm。應當注意(yi)，工(gong)(gong)(gong)件的加(jia)(jia)工(gong)(gong)(gong)精度不能完全(quan)由劃(hua)(hua)線(xian)(xian)(xian)確定(ding)，而應該在(zai)(zai)加(jia)(jia)工(gong)(gong)(gong)過程中通過測(ce)量來保證(zheng)。
