廠區劃線分為:熱熔標(biao)線(xian)，常(chang)溫冷漆(qi)標(biao)線(xian)，彩色(se)防滑(hua)標(biao)線(xian)，振(zhen)蕩(dang)防滑(hua)反光標(biao)線(xian)和預成型標(biao)線(xian)。 熱熔標(biao)線(xian)是我國道(dao)(dao)(dao)路標(biao)線(xian)上應用最廣的(de)一種標(biao)線(xian)。他施工時間(jian)短，耐磨性(xing)(xing)高(gao)，造價低。 道(dao)(dao)(dao)路交通標(biao)線(xian)主要(yao)(yao)劃設(she)于道(dao)(dao)(dao)路表(biao)面(mian)，經(jing)受(shou)(shou)日曬(shai)雨淋，風雪冰凍，遭(zao)受(shou)(shou)車(che)(che)輛的(de)沖擊磨耗，因(yin)此(ci)對其性(xing)(xing)能(neng)有嚴格的(de)要(yao)(yao)求。首先要(yao)(yao)求干燥時間(jian)短，操(cao)作(zuo)簡(jian)單，以(yi)減少交通干擾；其次要(yao)(yao)求反射能(neng)力強(qiang)，色(se)彩鮮明，反光度強(qiang)，使(shi)白天(tian)、夜(ye)晚都有良好的(de)能(neng)見度；第三，應具有抗滑(hua)性(xing)(xing)和耐磨性(xing)(xing)，以(yi)保證行車(che)(che)安(an)全(quan)和使(shi)用壽命。

根(gen)據圖樣和技術要(yao)求，在毛坯或(huo)半成品上(shang)用(yong)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)工(gong)具畫出加(jia)工(gong)界線(xian)(xian)(xian)(xian)(xian)(xian)，或(huo)劃(hua)(hua)(hua)出作(zuo)為(wei)(wei)基(ji)準的(de)(de)(de)點、線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)操作(zuo)過(guo)(guo)程稱(cheng)為(wei)(wei)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)。劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)分(fen)為(wei)(wei)平面(mian)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)和立體(ti)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)兩種。只需要(yao)在工(gong)件一(yi)個表(biao)面(mian)上(shang)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)即(ji)能(neng)(neng)明確(que)(que)表(biao)明加(jia)工(gong)界限(xian)的(de)(de)(de)，稱(cheng)之為(wei)(wei)平面(mian)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)；需要(yao)在工(gong)件幾(ji)個互成不同(tong)角度(du)（一(yi)般是(shi)互相(xiang)垂直）的(de)(de)(de)表(biao)面(mian)上(shang)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)，才能(neng)(neng)明確(que)(que)表(biao)明加(jia)工(gong)界限(xian)的(de)(de)(de)，稱(cheng)為(wei)(wei)立體(ti)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)。對劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)基(ji)本要(yao)求是(shi)線(xian)(xian)(xian)(xian)(xian)(xian)條清晰勻(yun)稱(cheng)，定型、定位尺寸準確(que)(que)。由(you)于劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)條有一(yi)定寬度(du)，一(yi)般要(yao)求精度(du)達到(dao)0.25-0.5mm。應當(dang)注意，工(gong)件的(de)(de)(de)加(jia)工(gong)精度(du)不能(neng)(neng)完(wan)全由(you)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)(xian)(xian)確(que)(que)定，而應該在加(jia)工(gong)過(guo)(guo)程中通(tong)過(guo)(guo)測量來保證。
