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(she)計(ji)要求劃出找平(ping)線(xian)、墻(qiang)體(ti)上的導線(xian)槽線(xian)，按設(she)計(ji)圖(tu)示位(wei)置(zhi)將暗敷在墻(qiang)體(ti)內的溫控器槽、分(fen)線(xian)盒槽及導線(xian)管(guan)槽剔好。

電熱膜地暖的安裝注意事項

1、電熱膜地暖安(an)裝(zhuang)過程中安(an)裝(zhuang)施工人員盡量以軟低鞋進場安(an)裝(zhuang)，禁止穿堅硬的鞋子施工。

2、地(di)暖安裝(zhuang)完畢24h后再逐(zhu)漸(jian)加溫(wen)，最好是(shi)每小(xiao)時升溫(wen)1度(du)左右，使木地(di)板(ban)逐(zhu)漸(jian)適應(ying)溫(wen)度(du)升溫(wen)。如果加溫(wen)過快(kuai)(kuai)，可能(neng)會使木地(di)板(ban)受熱過快(kuai)(kuai)，扭曲(qu)開(kai)裂等(deng)。在升溫(wen)前必須保持(chi)地(di)面干凈、干燥。

3、在地(di)熱采暖的木地(di)板上(shang)盡(jin)量不(bu)(bu)安放無腿的家(jia)具或裝(zhuang)飾，防止局部散熱不(bu)(bu)通暢，熱量悶在木地(di)板處，易(yi)產(chan)生(sheng)地(di)板因受(shou)熱不(bu)(bu)均變形。

4、通電(dian)試運行時，應測試本組電(dian)熱(re)膜的(de)總電(dian)阻(zu)(zu)值，與設計中(zhong)的(de)阻(zu)(zu)值對比，并(bing)作好詳細記錄。如有問(wen)題，需檢(jian)查整體(ti)的(de)線路及發熱(re)體(ti)，并(bing)及時排除。總電(dian)阻(zu)(zu)檢(jian)測合格(ge)后，再將所(suo)有在(zai)地面的(de)電(dian)線導(dao)管(guan)口(kou)做密封處理。
