一、瓷磚背膠是不是越粘越好

近來市場上有種說法，瓷磚背膠越(yue)(yue)粘手才代(dai)表品(pin)質(zhi)越(yue)(yue)好。其實不是(shi)的，瓷磚背膠乳液和(he)瓷磚的關(guan)系與(yu)膠水和(he)紙張的粘貼關(guan)系不一樣，瓷磚鋪貼并不是(shi)單純的依靠乳液的粘力(li)來(lai)粘合瓷磚。而是(shi)通過瓷磚背膠成膜后的柔韌性(xing)來(lai)緩沖瓷磚與(yu)墻面之間(jian)的應力(li)，從(cong)而達到讓瓷磚不空(kong)鼓脫落的目的。

影響瓷磚(zhuan)(zhuan)背(bei)(bei)膠(jiao)粘(zhan)(zhan)(zhan)力(li)(li)的(de)決(jue)定因(yin)素分別(bie)是初(chu)(chu)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)、持(chi)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)、耐(nai)候(hou)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)、內(nei)聚(ju)力(li)(li)，這四個瓷磚(zhuan)(zhuan)背(bei)(bei)膠(jiao)特(te)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)相(xiang)輔相(xiang)成相(xiang)互影響。初(chu)(chu)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)(yue)(yue)強(qiang)(qiang)，持(chi)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)(yue)(yue)弱(ruo)，瓷磚(zhuan)(zhuan)背(bei)(bei)膠(jiao)的(de)使用壽命越(yue)(yue)(yue)(yue)短。初(chu)(chu)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)(yue)(yue)強(qiang)(qiang)，耐(nai)水、耐(nai)高(gao)低溫、耐(nai)老化性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)越(yue)(yue)(yue)(yue)差，粘(zhan)(zhan)(zhan)結劑越(yue)(yue)(yue)(yue)容易因(yin)外部環境的(de)變化而性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)下降。初(chu)(chu)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)(yue)(yue)強(qiang)(qiang)，柔韌(ren)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)越(yue)(yue)(yue)(yue)強(qiang)(qiang)，內(nei)聚(ju)力(li)(li)越(yue)(yue)(yue)(yue)弱(ruo)，承重擠壓(ya)能(neng)力(li)(li)越(yue)(yue)(yue)(yue)差，在(zai)瓷磚(zhuan)(zhuan)和砂漿(jiang)重力(li)(li)的(de)長期作用下越(yue)(yue)(yue)(yue)容易出現(xian)空鼓、剝離、脫落現(xian)象。一(yi)桶好的(de)瓷磚(zhuan)(zhuan)背(bei)(bei)膠(jiao)，需(xu)要(yao)在(zai)這四個要(yao)素里面找到(dao)一(yi)個平衡點，把初(chu)(chu)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)下調，換取持(chi)粘(zhan)(zhan)(zhan)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)、耐(nai)候(hou)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)、內(nei)聚(ju)的(de)的(de)性(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)(xing)能(neng)提升，這樣瓷磚(zhuan)(zhuan)背(bei)(bei)膠(jiao)才可(ke)以在(zai)瓷磚(zhuan)(zhuan)鋪貼上墻后可(ke)以牢牢的(de)固(gu)定在(zai)墻面。

所以判(pan)斷瓷磚(zhuan)背膠品質好壞(huai)并不能從粘不粘手進行(xing)簡(jian)單判(pan)斷，而是(shi)要從柔韌性(xing)、耐候性(xing)、耐水性(xing)、耐堿性(xing)、是(shi)否環保(bao)等多方(fang)面進行(xing)考(kao)量。

二、如何判斷瓷磚背膠的好壞

有效辨別瓷磚背膠的質量，主要看這三點：

1、看檢測數據

質(zhi)量(liang)好(hao)不好(hao)數據來說話，數據也是判斷(duan)瓷(ci)磚背(bei)膠質(zhi)量(liang)的(de)(de)一個(ge)重要指(zhi)標(biao)，好(hao)的(de)(de)背(bei)膠則(ze)需通(tong)過(guo)行業標(biao)準的(de)(de)幾種測試項目（每項最低標(biao)準為0.5Mpa）。

2、聞氣味

利用扇(shan)氣(qi)入鼻(bi)法，靠近產(chan)品用手輕(qing)(qing)輕(qing)(qing)扇(shan)風，聞(wen)一下(xia)觀察一下(xia)是否有(you)(you)刺(ci)激性氣(qi)味，品質(zhi)優良的(de)背膠(jiao)雖略(lve)有(you)(you)氣(qi)味，但(dan)不至(zhi)于有(you)(you)明(ming)顯(xian)刺(ci)鼻(bi)氣(qi)味，相(xiang)反品質(zhi)較差的(de)產(chan)品就會有(you)(you)明(ming)顯(xian)刺(ci)鼻(bi)性氣(qi)味。

3、進行施工測試

判斷瓷磚背膠的(de)(de)好壞(huai)最(zui)直(zhi)接的(de)(de)方法便(bian)是開桶使(shi)用測試，觀察(cha)其耐(nai)(nai)溫性、耐(nai)(nai)候性、耐(nai)(nai)水性、耐(nai)(nai)老化等，這個(ge)過程(cheng)中，正確施工也很重要。合格(ge)的(de)(de)產品+正確的(de)(de)施工才能發(fa)揮材(cai)料的(de)(de)最(zui)佳性能。
