工業公司劃線分為:熱(re)熔(rong)(rong)標(biao)線(xian)(xian)(xian)，常溫(wen)冷漆(qi)標(biao)線(xian)(xian)(xian)，彩(cai)色防滑(hua)(hua)標(biao)線(xian)(xian)(xian)，振(zhen)蕩防滑(hua)(hua)反光標(biao)線(xian)(xian)(xian)和(he)預成(cheng)型標(biao)線(xian)(xian)(xian)。 熱(re)熔(rong)(rong)標(biao)線(xian)(xian)(xian)是我國道(dao)路(lu)標(biao)線(xian)(xian)(xian)上(shang)應(ying)用最(zui)廣的一(yi)種標(biao)線(xian)(xian)(xian)。他(ta)施工時間短(duan)，耐磨性(xing)高，造價低。 道(dao)路(lu)交(jiao)通標(biao)線(xian)(xian)(xian)主要(yao)劃設(she)于(yu)道(dao)路(lu)表(biao)面，經受日曬雨淋，風雪冰凍，遭受車輛的沖擊磨耗，因此(ci)對其(qi)性(xing)能(neng)有嚴格的要(yao)求。首先(xian)要(yao)求干(gan)燥時間短(duan)，操作簡(jian)單，以減少交(jiao)通干(gan)擾；其(qi)次要(yao)求反射能(neng)力強，色彩(cai)鮮明，反光度(du)(du)強，使白天、夜晚都有良好的能(neng)見(jian)度(du)(du)；第三，應(ying)具有抗滑(hua)(hua)性(xing)和(he)耐磨性(xing)，以保證行車安(an)全和(he)使用壽命。

根據圖(tu)樣和技術要求(qiu)，在(zai)(zai)(zai)毛坯或半成(cheng)品上(shang)用(yong)劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)工(gong)具畫出加(jia)工(gong)界(jie)線(xian)(xian)(xian)(xian)，或劃(hua)(hua)(hua)(hua)(hua)(hua)出作為基準(zhun)的(de)點、線(xian)(xian)(xian)(xian)的(de)操作過(guo)(guo)程稱為劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)。劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)分為平面(mian)(mian)(mian)劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)和立體劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)兩種(zhong)。只需(xu)要在(zai)(zai)(zai)工(gong)件一(yi)個表(biao)面(mian)(mian)(mian)上(shang)劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)即能(neng)明(ming)確(que)表(biao)明(ming)加(jia)工(gong)界(jie)限的(de)，稱之(zhi)為平面(mian)(mian)(mian)劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)；需(xu)要在(zai)(zai)(zai)工(gong)件幾個互成(cheng)不(bu)同角度(du)（一(yi)般是互相(xiang)垂直）的(de)表(biao)面(mian)(mian)(mian)上(shang)劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)，才能(neng)明(ming)確(que)表(biao)明(ming)加(jia)工(gong)界(jie)限的(de)，稱為立體劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)。對(dui)劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)的(de)基本要求(qiu)是線(xian)(xian)(xian)(xian)條(tiao)(tiao)清晰勻(yun)稱，定(ding)型、定(ding)位尺寸準(zhun)確(que)。由于劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)的(de)線(xian)(xian)(xian)(xian)條(tiao)(tiao)有一(yi)定(ding)寬度(du)，一(yi)般要求(qiu)精度(du)達到0.25-0.5mm。應當注意，工(gong)件的(de)加(jia)工(gong)精度(du)不(bu)能(neng)完全由劃(hua)(hua)(hua)(hua)(hua)(hua)線(xian)(xian)(xian)(xian)確(que)定(ding)，而(er)應該(gai)在(zai)(zai)(zai)加(jia)工(gong)過(guo)(guo)程中通過(guo)(guo)測量來保證(zheng)。
