電熱膜地暖的安裝注意事項
1、電熱膜地暖安(an)(an)裝(zhuang)過程中(zhong)安(an)(an)裝(zhuang)施工人員盡量(liang)以軟低鞋(xie)進場安(an)(an)裝(zhuang),禁止穿(chuan)堅硬的鞋(xie)子施工。
2、地暖(nuan)安裝完(wan)畢24h后再逐(zhu)漸加(jia)溫(wen)(wen),最好是(shi)每小時(shi)升溫(wen)(wen)1度左右,使木地板逐(zhu)漸適應溫(wen)(wen)度升溫(wen)(wen)。如果(guo)加(jia)溫(wen)(wen)過快,可能會使木地板受(shou)熱(re)過快,扭曲開裂等。在升溫(wen)(wen)前必須保持地面干凈、干燥。
3、在地熱(re)采(cai)暖的木(mu)地板(ban)上盡量不安放無腿的家具或裝飾,防止局(ju)部散(san)熱(re)不通(tong)暢,熱(re)量悶在木(mu)地板(ban)處,易產生地板(ban)因受(shou)熱(re)不均(jun)變(bian)形。
4、通(tong)電(dian)(dian)試運行時,應測(ce)試本(ben)組電(dian)(dian)熱(re)(re)膜的(de)總電(dian)(dian)阻(zu)值(zhi),與設計中的(de)阻(zu)值(zhi)對比,并(bing)作(zuo)好詳(xiang)細記錄。如(ru)有(you)問題,需(xu)檢(jian)查整體的(de)線路(lu)及(ji)(ji)發熱(re)(re)體,并(bing)及(ji)(ji)時排除。總電(dian)(dian)阻(zu)檢(jian)測(ce)合格(ge)后,再將所(suo)有(you)在地面的(de)電(dian)(dian)線導管(guan)口做(zuo)密封處(chu)理。
