2019/10/28 15:56:17

1.如果是為了防止泛堿、生銹等,一般采用有機硅型大理石養護劑;如果是為了提高綜合防水和抗污能力,一般要采用有機氟型大理石養護劑。

2.有些結構致密的大理石建議選用油性大理石養護劑。油性大理石養護劑滲透力強,可以更深入到大理石內部;對于結構一般的大理石,油性與水性大理石養護劑都可以選用。

3.對于是餐廳、灶臺等容易污染的地方,最好采用有機氟型大理石養護劑以便提高大理石表面的抗污能力。

4.對于室外的大理石,可以選用有機硅型養護劑,但要求產品的抗紫外線能力、耐水性和耐酸性都比較好。

5.對于濕貼或灌漿安裝的大理石,建議選用大理石底面專用養護劑。而且還應注意養護劑的耐堿性,不能影響大理石與水泥的粘接牢度,否則容易造成石材脫落。

6.對于毛面大理石表面的膜型養護處理,應采用有機硅為原料的成膜型大理石養護劑,這種產品硬度好,粘接強度高,而且不易發黃;最好不要采用以丙烯酸為原料的地面密封劑,這種產品主要用于底面密封,在大理石表面使用會使大理石脫皮和變色。

7.對于顏色較深的大理石,由于使用防護劑后很容易變色,所以選擇防護劑時一定要先在不顯眼處做小樣測試。
