工業園廠區劃線分(fen)為:熱(re)熔標(biao)線，常溫冷漆標(biao)線，彩色防滑(hua)標(biao)線，振蕩防滑(hua)反光標(biao)線和(he)預(yu)成型標(biao)線。 熱(re)熔標(biao)線是我國(guo)道(dao)路(lu)(lu)標(biao)線上應用(yong)最廣的(de)一種標(biao)線。他(ta)施工時(shi)間短(duan)，耐(nai)磨性高(gao)，造價低。 道(dao)路(lu)(lu)交(jiao)通標(biao)線主要(yao)劃(hua)設于道(dao)路(lu)(lu)表面，經受(shou)(shou)日曬雨淋，風(feng)雪冰凍，遭受(shou)(shou)車輛的(de)沖擊磨耗，因此對其性能(neng)有嚴格的(de)要(yao)求(qiu)。首先要(yao)求(qiu)干(gan)燥時(shi)間短(duan)，操作簡(jian)單，以減少交(jiao)通干(gan)擾；其次要(yao)求(qiu)反射(she)能(neng)力(li)強，色彩鮮(xian)明，反光度強，使白天、夜晚都有良(liang)好的(de)能(neng)見度；第三，應具有抗滑(hua)性和(he)耐(nai)磨性，以保(bao)證行(xing)車安全和(he)使用(yong)壽命。

根據圖樣和技術要(yao)求，在毛坯或半成(cheng)品上(shang)用(yong)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)工(gong)具畫(hua)出加(jia)工(gong)界(jie)線(xian)(xian)(xian)(xian)，或劃(hua)(hua)(hua)出作(zuo)為基準的(de)(de)(de)點、線(xian)(xian)(xian)(xian)的(de)(de)(de)操作(zuo)過程(cheng)稱為劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)。劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)分為平(ping)面(mian)(mian)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)和立體(ti)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)兩種。只需要(yao)在工(gong)件(jian)一個表面(mian)(mian)上(shang)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)即能明(ming)確(que)表明(ming)加(jia)工(gong)界(jie)限的(de)(de)(de)，稱之為平(ping)面(mian)(mian)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)；需要(yao)在工(gong)件(jian)幾個互成(cheng)不同角度（一般是互相垂直）的(de)(de)(de)表面(mian)(mian)上(shang)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)，才能明(ming)確(que)表明(ming)加(jia)工(gong)界(jie)限的(de)(de)(de)，稱為立體(ti)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)。對劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)的(de)(de)(de)基本要(yao)求是線(xian)(xian)(xian)(xian)條清晰(xi)勻稱，定型、定位尺寸準確(que)。由(you)于劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)的(de)(de)(de)線(xian)(xian)(xian)(xian)條有(you)一定寬(kuan)度，一般要(yao)求精(jing)度達到0.25-0.5mm。應當(dang)注(zhu)意，工(gong)件(jian)的(de)(de)(de)加(jia)工(gong)精(jing)度不能完全由(you)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)確(que)定，而應該在加(jia)工(gong)過程(cheng)中通(tong)過測量來保證。
