公司車間劃線分為:熱(re)熔標(biao)(biao)(biao)線(xian)(xian)，常溫冷漆標(biao)(biao)(biao)線(xian)(xian)，彩(cai)色(se)防滑(hua)標(biao)(biao)(biao)線(xian)(xian)，振蕩防滑(hua)反光(guang)標(biao)(biao)(biao)線(xian)(xian)和(he)預(yu)成(cheng)型標(biao)(biao)(biao)線(xian)(xian)。 熱(re)熔標(biao)(biao)(biao)線(xian)(xian)是我國道路(lu)標(biao)(biao)(biao)線(xian)(xian)上應用最(zui)廣的(de)一種標(biao)(biao)(biao)線(xian)(xian)。他(ta)施工時間(jian)短，耐磨(mo)(mo)(mo)性高，造價(jia)低(di)。 道路(lu)交(jiao)通(tong)標(biao)(biao)(biao)線(xian)(xian)主要劃設于(yu)道路(lu)表面，經受(shou)日曬雨淋，風雪冰凍，遭(zao)受(shou)車(che)輛(liang)的(de)沖擊磨(mo)(mo)(mo)耗，因此(ci)對其性能(neng)有嚴格(ge)的(de)要求。首先(xian)要求干(gan)燥(zao)時間(jian)短，操作(zuo)簡單(dan)，以(yi)(yi)減(jian)少(shao)交(jiao)通(tong)干(gan)擾(rao)；其次(ci)要求反射能(neng)力強，色(se)彩(cai)鮮明(ming)，反光(guang)度強，使(shi)白(bai)天(tian)、夜晚(wan)都有良(liang)好的(de)能(neng)見度；第(di)三(san)，應具有抗滑(hua)性和(he)耐磨(mo)(mo)(mo)性，以(yi)(yi)保證行車(che)安全和(he)使(shi)用壽命。

根(gen)據圖樣和技術(shu)要(yao)求(qiu)(qiu)，在毛坯(pi)或半成品(pin)上用劃(hua)(hua)(hua)線(xian)(xian)(xian)工(gong)具畫出(chu)加(jia)工(gong)界(jie)線(xian)(xian)(xian)，或劃(hua)(hua)(hua)出(chu)作為(wei)基準的(de)(de)點、線(xian)(xian)(xian)的(de)(de)操作過(guo)程(cheng)稱為(wei)劃(hua)(hua)(hua)線(xian)(xian)(xian)。劃(hua)(hua)(hua)線(xian)(xian)(xian)分為(wei)平(ping)面劃(hua)(hua)(hua)線(xian)(xian)(xian)和立體劃(hua)(hua)(hua)線(xian)(xian)(xian)兩(liang)種。只需(xu)要(yao)在工(gong)件(jian)一(yi)個(ge)表面上劃(hua)(hua)(hua)線(xian)(xian)(xian)即(ji)能明確(que)表明加(jia)工(gong)界(jie)限的(de)(de)，稱之(zhi)為(wei)平(ping)面劃(hua)(hua)(hua)線(xian)(xian)(xian)；需(xu)要(yao)在工(gong)件(jian)幾個(ge)互成不同(tong)角(jiao)度(du)（一(yi)般(ban)是(shi)互相(xiang)垂直）的(de)(de)表面上劃(hua)(hua)(hua)線(xian)(xian)(xian)，才能明確(que)表明加(jia)工(gong)界(jie)限的(de)(de)，稱為(wei)立體劃(hua)(hua)(hua)線(xian)(xian)(xian)。對劃(hua)(hua)(hua)線(xian)(xian)(xian)的(de)(de)基本要(yao)求(qiu)(qiu)是(shi)線(xian)(xian)(xian)條(tiao)清晰勻(yun)稱，定(ding)型、定(ding)位尺寸準確(que)。由于劃(hua)(hua)(hua)線(xian)(xian)(xian)的(de)(de)線(xian)(xian)(xian)條(tiao)有一(yi)定(ding)寬度(du)，一(yi)般(ban)要(yao)求(qiu)(qiu)精度(du)達到0.25-0.5mm。應(ying)當注意，工(gong)件(jian)的(de)(de)加(jia)工(gong)精度(du)不能完全由劃(hua)(hua)(hua)線(xian)(xian)(xian)確(que)定(ding)，而應(ying)該在加(jia)工(gong)過(guo)程(cheng)中通過(guo)測量來保證。
