電熱膜地暖施工步驟有哪些
一、準備工作
首先要檢查一遍地面是否平整,在地面找平之后將地面清掃干凈,然后準備好電源線和探頭,確定好溫控器和接線盒的位置。按照電熱膜地暖施工設計(ji)要(yao)求劃出找平(ping)線、墻體(ti)上(shang)的導線槽(cao)(cao)線,按設計(ji)圖(tu)示(shi)位置將暗敷在墻體(ti)內的溫控器槽(cao)(cao)、分線盒槽(cao)(cao)及導線管槽(cao)(cao)剔好。

電熱膜地暖的安裝注意事項
1、電熱膜地暖安裝(zhuang)過程中安裝(zhuang)施工(gong)人員盡量以軟低鞋進場安裝(zhuang),禁止穿堅(jian)硬的鞋子施工(gong)。
2、地(di)暖安裝完畢24h后(hou)再逐(zhu)漸(jian)加溫(wen),最好是每小時(shi)升溫(wen)1度(du)左(zuo)右,使(shi)木地(di)板(ban)逐(zhu)漸(jian)適應溫(wen)度(du)升溫(wen)。如果加溫(wen)過快,可(ke)能會使(shi)木地(di)板(ban)受熱過快,扭曲(qu)開裂(lie)等。在升溫(wen)前必(bi)須(xu)保持地(di)面干凈、干燥。
3、在地(di)熱采暖(nuan)的木(mu)地(di)板上盡量不安放(fang)無(wu)腿(tui)的家(jia)具或裝(zhuang)飾,防止(zhi)局部散熱不通暢,熱量悶在木(mu)地(di)板處,易產生(sheng)地(di)板因受熱不均變形。
4、通電(dian)(dian)試(shi)運行時(shi),應測試(shi)本組電(dian)(dian)熱膜(mo)的(de)總(zong)(zong)電(dian)(dian)阻值,與設(she)計中(zhong)的(de)阻值對(dui)比(bi),并(bing)作(zuo)好詳細記錄。如有(you)問題,需檢查整體的(de)線(xian)路及發熱體,并(bing)及時(shi)排除。總(zong)(zong)電(dian)(dian)阻檢測合格(ge)后,再將所有(you)在地面的(de)電(dian)(dian)線(xian)導管口做密封處理(li)。
