工業廠區劃線分為:熱(re)熔標(biao)(biao)線(xian)(xian)(xian)(xian)，常溫冷漆標(biao)(biao)線(xian)(xian)(xian)(xian)，彩(cai)色防滑標(biao)(biao)線(xian)(xian)(xian)(xian)，振蕩防滑反(fan)光標(biao)(biao)線(xian)(xian)(xian)(xian)和預成型(xing)標(biao)(biao)線(xian)(xian)(xian)(xian)。 熱(re)熔標(biao)(biao)線(xian)(xian)(xian)(xian)是(shi)我(wo)國道(dao)路標(biao)(biao)線(xian)(xian)(xian)(xian)上應用(yong)最廣的(de)一(yi)種(zhong)標(biao)(biao)線(xian)(xian)(xian)(xian)。他施工時間短(duan)，耐磨(mo)性(xing)(xing)高，造價(jia)低。 道(dao)路交通標(biao)(biao)線(xian)(xian)(xian)(xian)主(zhu)要劃設(she)于道(dao)路表面，經受(shou)日曬雨淋，風雪冰(bing)凍(dong)，遭受(shou)車輛的(de)沖擊磨(mo)耗，因(yin)此對其(qi)性(xing)(xing)能有嚴格的(de)要求。首先要求干燥時間短(duan)，操作簡單，以(yi)減(jian)少交通干擾(rao)；其(qi)次要求反(fan)射能力強(qiang)，色彩(cai)鮮明，反(fan)光度強(qiang)，使(shi)白天、夜晚(wan)都有良好的(de)能見度；第(di)三，應具(ju)有抗滑性(xing)(xing)和耐磨(mo)性(xing)(xing)，以(yi)保證行車安(an)全和使(shi)用(yong)壽(shou)命。

根據圖樣和(he)(he)技術要求，在毛坯(pi)或半成品上(shang)(shang)用劃(hua)(hua)線(xian)(xian)(xian)工(gong)具畫出(chu)加工(gong)界(jie)線(xian)(xian)(xian)，或劃(hua)(hua)出(chu)作為(wei)(wei)基(ji)(ji)準(zhun)的點、線(xian)(xian)(xian)的操(cao)作過(guo)程稱(cheng)為(wei)(wei)劃(hua)(hua)線(xian)(xian)(xian)。劃(hua)(hua)線(xian)(xian)(xian)分為(wei)(wei)平面(mian)(mian)(mian)劃(hua)(hua)線(xian)(xian)(xian)和(he)(he)立(li)體劃(hua)(hua)線(xian)(xian)(xian)兩(liang)種。只需要在工(gong)件一(yi)(yi)個(ge)表(biao)(biao)面(mian)(mian)(mian)上(shang)(shang)劃(hua)(hua)線(xian)(xian)(xian)即能明確(que)表(biao)(biao)明加工(gong)界(jie)限的，稱(cheng)之為(wei)(wei)平面(mian)(mian)(mian)劃(hua)(hua)線(xian)(xian)(xian)；需要在工(gong)件幾個(ge)互成不同角度（一(yi)(yi)般是(shi)互相垂直(zhi)）的表(biao)(biao)面(mian)(mian)(mian)上(shang)(shang)劃(hua)(hua)線(xian)(xian)(xian)，才能明確(que)表(biao)(biao)明加工(gong)界(jie)限的，稱(cheng)為(wei)(wei)立(li)體劃(hua)(hua)線(xian)(xian)(xian)。對劃(hua)(hua)線(xian)(xian)(xian)的基(ji)(ji)本要求是(shi)線(xian)(xian)(xian)條(tiao)(tiao)清晰(xi)勻(yun)稱(cheng)，定型、定位尺寸準(zhun)確(que)。由于劃(hua)(hua)線(xian)(xian)(xian)的線(xian)(xian)(xian)條(tiao)(tiao)有(you)一(yi)(yi)定寬度，一(yi)(yi)般要求精度達到(dao)0.25-0.5mm。應(ying)當注意，工(gong)件的加工(gong)精度不能完全由劃(hua)(hua)線(xian)(xian)(xian)確(que)定，而應(ying)該在加工(gong)過(guo)程中通過(guo)測量(liang)來保證(zheng)。
