觀察斷面接口
市場上很多銅(tong)(tong)(tong)質全銅(tong)(tong)(tong)水龍(long)頭(tou)往往是(shi)(shi)以表面鍍銅(tong)(tong)(tong)處(chu)理,而其(qi)內(nei)部(bu)材(cai)(cai)(cai)質并非為(wei)銅(tong)(tong)(tong)質材(cai)(cai)(cai)質,因此在選購時一(yi)定(ding)要(yao)多加注意,細心觀察龍(long)頭(tou)的斷(duan)面接口是(shi)(shi)否為(wei)銅(tong)(tong)(tong)體材(cai)(cai)(cai)質,因此選購全銅(tong)(tong)(tong)水龍(long)頭(tou)時你可以用小刀在龍(long)頭(tou)的斷(duan)面接口處(chu)刮一(yi)下看看其(qi)內(nei)部(bu)材(cai)(cai)(cai)質如(ru)何(he)。
龍(long)頭(tou)閥(fa)芯選購
在(zai)選(xuan)(xuan)購全銅水龍頭(tou)時一(yi)定(ding)不(bu)要(yao)(yao)忘記對(dui)其閥芯進行挑選(xuan)(xuan),質優的全銅水龍頭(tou)閥芯一(yi)般以陶瓷材(cai)質為主,其密(mi)封性能好,耐(nai)磨,因此在(zai)選(xuan)(xuan)購全銅水龍頭(tou)時一(yi)定(ding)要(yao)(yao)確保其閥芯材(cai)質,如(ru)果不(bu)好挑選(xuan)(xuan),建(jian)議(yi)讓商家出示相關證據,并(bing)將購買條款寫入(ru)合同中(zhong),以備后續使用過程(cheng)中(zhong)有保障。
多用手摸摸
為了確保所選購(gou)的全(quan)銅(tong)水(shui)龍頭為全(quan)銅(tong)材(cai)質(zhi),因(yin)此在選購(gou)過程中建(jian)議(yi)(yi)盡量(liang)的用(yong)手多摸(mo)摸(mo)龍頭表面(mian),并(bing)且銅(tong)材(cai)質(zhi)電鍍后其產品用(yong)手摸(mo)起來有厚重感,其表面(mian)阻(zu)力較大,如果摸(mo)起來其表面(mian)比(bi)較光滑(hua)時,則說明其不(bu)是銅(tong)質(zhi)材(cai)質(zhi),建(jian)議(yi)(yi)不(bu)要購(gou)買。
