小廠區劃線分為:熱(re)熔標線(xian)(xian)，常溫冷漆(qi)標線(xian)(xian)，彩色(se)防滑標線(xian)(xian)，振蕩(dang)防滑反光(guang)標線(xian)(xian)和預(yu)成(cheng)型標線(xian)(xian)。 熱(re)熔標線(xian)(xian)是(shi)我國道路標線(xian)(xian)上應(ying)用最廣的(de)一(yi)種(zhong)標線(xian)(xian)。他施(shi)工時(shi)間短，耐磨(mo)性高，造價低(di)。 道路交通標線(xian)(xian)主要(yao)劃(hua)設于道路表(biao)面，經受日曬雨淋，風(feng)雪冰凍，遭受車輛的(de)沖(chong)擊磨(mo)耗，因此對其(qi)性能(neng)有嚴(yan)格的(de)要(yao)求。首先要(yao)求干燥時(shi)間短，操作簡單，以(yi)減少交通干擾；其(qi)次要(yao)求反射能(neng)力強(qiang)(qiang)，色(se)彩鮮明(ming)，反光(guang)度強(qiang)(qiang)，使(shi)白天、夜(ye)晚都有良好(hao)的(de)能(neng)見度；第三，應(ying)具有抗滑性和耐磨(mo)性，以(yi)保(bao)證行車安全(quan)和使(shi)用壽(shou)命。

根據圖樣和技術要求(qiu)，在(zai)毛(mao)坯或半成(cheng)品上用劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)工(gong)(gong)具(ju)畫出(chu)加工(gong)(gong)界線(xian)(xian)(xian)(xian)(xian)，或劃(hua)(hua)(hua)出(chu)作為(wei)基準的(de)(de)點、線(xian)(xian)(xian)(xian)(xian)的(de)(de)操作過程稱(cheng)為(wei)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)。劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)分為(wei)平(ping)面(mian)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)和立體劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)兩種。只需要在(zai)工(gong)(gong)件一(yi)個(ge)(ge)表面(mian)上劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)即能(neng)明確(que)(que)表明加工(gong)(gong)界限的(de)(de)，稱(cheng)之為(wei)平(ping)面(mian)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)；需要在(zai)工(gong)(gong)件幾個(ge)(ge)互成(cheng)不同角度（一(yi)般是互相垂直）的(de)(de)表面(mian)上劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)，才能(neng)明確(que)(que)表明加工(gong)(gong)界限的(de)(de)，稱(cheng)為(wei)立體劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)。對劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)的(de)(de)基本要求(qiu)是線(xian)(xian)(xian)(xian)(xian)條(tiao)清(qing)晰勻稱(cheng)，定(ding)型(xing)、定(ding)位尺寸準確(que)(que)。由于劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)的(de)(de)線(xian)(xian)(xian)(xian)(xian)條(tiao)有一(yi)定(ding)寬度，一(yi)般要求(qiu)精度達到(dao)0.25-0.5mm。應當注意，工(gong)(gong)件的(de)(de)加工(gong)(gong)精度不能(neng)完全(quan)由劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)確(que)(que)定(ding)，而應該在(zai)加工(gong)(gong)過程中通過測量(liang)來保證。
