排水板行業簡介

一、排水板的價格是多少

排水板是一種土工材料，鋪設在屋頂、車庫頂板、建筑物基礎上層或下層等場所，起到排水的作用。市面上排水板的價格一般是按面積計算的，計算時，以克重折算出每平米的價格，一般來說，16mm排水板價格大約在9元每平方左右，20mm排水板價格大約在10.5元每平方左右，30mm排水板價格大約在13.5元每平方左右。當然，每平米的重量也是要根據凸高的不同來確定重量，例如凸高2cm的排水板，推薦重量在1400g左右每一米，那么價格大約在8元左右每平米，如果做1000克左右，每平米價格在5.8元左右。另外，排水板作為塑料制品，其使用的材質、型號、選擇的生產廠家、購買數量等因素也會影響到它的價格。選購排水板時，除了價格外，還要注意選擇一個靠譜的排水板品牌，并可以通過看、壓(ya)、折、提四個方法簡單判斷(duan)排(pai)水板(ban)的(de)質量(liang)好(hao)壞。

二、排水板和土工布怎么鋪裝

1、首先檢查基底(di)，保證(zheng)基底(di)的干(gan)燥(zao)平整，含水(shui)(shui)量少于(yu)9%。2、然后用刷子均勻(yun)地(di)刷上瀝青溶液，等干(gan)掉后鋪裝排(pai)水(shui)(shui)板(ban)，把排(pai)水(shui)(shui)板(ban)四邊的齒孔扣緊，杯(bei)狀口要向上。3、再在上面(mian)蓋土木布(bu)，以(yi)10-20公分的距離重疊。4、接著撒上中粗砂、鋪上種(zhong)植土。5、最后做好養(yang)護即可。

四、排水板凸點朝上還是朝下

排(pai)水(shui)(shui)(shui)(shui)板有凹面(mian)和凸面(mian)，很(hen)多朋友在(zai)(zai)安裝(zhuang)時(shi)不知道應(ying)該(gai)把凸點(dian)那面(mian)朝(chao)(chao)上(shang)(shang)安裝(zhuang)還(huan)是(shi)(shi)(shi)把凹面(mian)朝(chao)(chao)上(shang)(shang)安裝(zhuang)，其實這需要(yao)根據水(shui)(shui)(shui)(shui)流的(de)方向來定。如(ru)(ru)果是(shi)(shi)(shi)裝(zhuang)在(zai)(zai)地(di)面(mian)上(shang)(shang)的(de)排(pai)水(shui)(shui)(shui)(shui)板，水(shui)(shui)(shui)(shui)從地(di)下上(shang)(shang)來的(de)，那么凸點(dian)應(ying)該(gai)朝(chao)(chao)下，如(ru)(ru)果是(shi)(shi)(shi)安裝(zhuang)在(zai)(zai)頂部的(de)排(pai)水(shui)(shui)(shui)(shui)板，水(shui)(shui)(shui)(shui)是(shi)(shi)(shi)從上(shang)(shang)面(mian)下來的(de)，那么凸點(dian)就應(ying)該(gai)朝(chao)(chao)上(shang)(shang)，總而(er)言之，就是(shi)(shi)(shi)凸點(dian)的(de)方向需要(yao)作(zuo)為迎(ying)水(shui)(shui)(shui)(shui)面(mian)。用戶在(zai)(zai)安裝(zhuang)的(de)時(shi)候，需要(yao)根據實際(ji)需求(qiu)來進行操(cao)作(zuo)，避免影(ying)響排(pai)水(shui)(shui)(shui)(shui)。
