管(guan)道(dao)(dao)(dao)清(qing)(qing)(qing)(qing)洗常用(yong)的(de)清(qing)(qing)(qing)(qing)洗方法有(you)化(hua)學清(qing)(qing)(qing)(qing)洗和(he)物(wu)理清(qing)(qing)(qing)(qing)洗二種。不損傷下(xia)(xia)(xia)水(shui)(shui)管(guan)道(dao)(dao)(dao)(包括PVC管(guan)道(dao)(dao)(dao))，不破壞電鍍層使用(yong)方法：清(qing)(qing)(qing)(qing)除洗滌盆或潔具(ju)中(zhong)的(de)積水(shui)(shui)，倒50-100G本(ben)品入下(xia)(xia)(xia)水(shui)(shui)管(guan)道(dao)(dao)(dao)中(zhong)，如果下(xia)(xia)(xia)水(shui)(shui)道(dao)(dao)(dao)內沒有(you)水(shui)(shui)，請(qing)加入半(ban)杯清(qing)(qing)(qing)(qing)水(shui)(shui)。管(guan)道(dao)(dao)(dao)堵(du)塞的(de)原因管(guan)道(dao)(dao)(dao)堵(du)塞的(de)原因非常復(fu)雜，總體上(shang)可分以下(xia)(xia)(xia)幾(ji)種情形：慢(man)性堵(du)塞：管(guan)道(dao)(dao)(dao)內流體物(wu)質經年(nian)累月地慢(man)慢(man)的(de)附著在管(guan)道(dao)(dao)(dao)壁(bi)上(shang)使管(guan)道(dao)(dao)(dao)逐(zhu)漸(jian)變(bian)細，管(guan)道(dao)(dao)(dao)自身和(he)其他物(wu)質發(fa)生化(hua)學反應也逐(zhu)漸(jian)變(bian)細，慢(man)慢(man)的(de)管(guan)道(dao)(dao)(dao)就會堵(du)塞了。編輯(ji)本(ben)段(duan)管(guan)道(dao)(dao)(dao)疏通劑管(guan)道(dao)(dao)(dao)疏下(xia)(xia)(xia)水(shui)(shui)道(dao)(dao)(dao)，并密封住下(xia)(xia)(xia)水(shui)(shui)口，再放入足(zu)量的(de)清(qing)(qing)(qing)(qing)水(shui)(shui)，快速地向下(xia)(xia)(xia)水(shui)(shui)道(dao)(dao)(dao)里(li)打氣，管(guan)道(dao)(dao)(dao)就能疏通
