學校運動場劃線分為:熱(re)熔(rong)標(biao)(biao)線(xian)(xian)，常溫(wen)冷漆標(biao)(biao)線(xian)(xian)，彩色防(fang)滑(hua)標(biao)(biao)線(xian)(xian)，振蕩防(fang)滑(hua)反(fan)光標(biao)(biao)線(xian)(xian)和(he)預成型標(biao)(biao)線(xian)(xian)。 熱(re)熔(rong)標(biao)(biao)線(xian)(xian)是我國(guo)道(dao)路(lu)標(biao)(biao)線(xian)(xian)上(shang)應(ying)用最廣的(de)一種標(biao)(biao)線(xian)(xian)。他(ta)施工時間(jian)短(duan)，耐磨(mo)性(xing)(xing)高(gao)，造價低。 道(dao)路(lu)交(jiao)通(tong)標(biao)(biao)線(xian)(xian)主要(yao)劃設于道(dao)路(lu)表面，經受(shou)日曬雨淋，風雪冰凍，遭受(shou)車(che)輛(liang)的(de)沖擊磨(mo)耗，因此(ci)對其性(xing)(xing)能(neng)有(you)嚴(yan)格的(de)要(yao)求。首先要(yao)求干燥時間(jian)短(duan)，操作簡單，以減少交(jiao)通(tong)干擾；其次要(yao)求反(fan)射(she)能(neng)力強(qiang)，色彩鮮明，反(fan)光度強(qiang)，使(shi)白天、夜晚都(dou)有(you)良好的(de)能(neng)見度；第三，應(ying)具有(you)抗滑(hua)性(xing)(xing)和(he)耐磨(mo)性(xing)(xing)，以保證行車(che)安全(quan)和(he)使(shi)用壽命(ming)。

根據圖(tu)樣和技術(shu)要(yao)(yao)求，在(zai)毛坯或(huo)(huo)半成品上用劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)工(gong)具畫(hua)出加(jia)(jia)工(gong)界線(xian)(xian)(xian)(xian)，或(huo)(huo)劃(hua)(hua)(hua)出作為(wei)(wei)基準(zhun)的點(dian)、線(xian)(xian)(xian)(xian)的操作過(guo)(guo)程(cheng)稱(cheng)為(wei)(wei)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)。劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)分為(wei)(wei)平面劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)和立(li)體劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)兩種。只需要(yao)(yao)在(zai)工(gong)件(jian)一(yi)個表(biao)面上劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)即能明確表(biao)明加(jia)(jia)工(gong)界限(xian)的，稱(cheng)之為(wei)(wei)平面劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)；需要(yao)(yao)在(zai)工(gong)件(jian)幾個互(hu)成不同角度（一(yi)般(ban)是互(hu)相垂直(zhi)）的表(biao)面上劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)，才能明確表(biao)明加(jia)(jia)工(gong)界限(xian)的，稱(cheng)為(wei)(wei)立(li)體劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)。對劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)的基本要(yao)(yao)求是線(xian)(xian)(xian)(xian)條(tiao)清晰勻稱(cheng)，定(ding)型、定(ding)位(wei)尺寸準(zhun)確。由(you)于(yu)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)的線(xian)(xian)(xian)(xian)條(tiao)有一(yi)定(ding)寬度，一(yi)般(ban)要(yao)(yao)求精(jing)度達到0.25-0.5mm。應當注(zhu)意(yi)，工(gong)件(jian)的加(jia)(jia)工(gong)精(jing)度不能完(wan)全由(you)劃(hua)(hua)(hua)線(xian)(xian)(xian)(xian)確定(ding)，而應該在(zai)加(jia)(jia)工(gong)過(guo)(guo)程(cheng)中通過(guo)(guo)測量來(lai)保證。
