Features: This standard is a revision of JC/T572-1994 "Alkali-Resistant E-glass Unidirectional Roving." This standard primarily references the relevant standards of the International GRC Association, GRCA105/0286—2001, and compared to the original standard, its technical content has the following changes:
——Based on international market demand and domestic production practices, the classification of alkali-resistant unidirectional roving is divided into L-type and H-type according to the different ZrO2 content in the main chemical composition;
——According to industrial technological progress, higher technical requirements have been proposed for the product compared to previous standards;
——Since the alkali resistance of alkali-resistant glass fiber depends on the chemical composition of the glass, and the alkali resistance test method in the original standard is not suitable for product testing, the alkali resistance test method has been canceled.
This standard was proposed by the former National Building Materials Industry Administration.
This standard is under the jurisdiction of the National Fiberglass Standardization Technical Committee (CSBTS/245).
The responsible drafting unit of this standard is the China Building Materials Academy.
The participating drafting units of this standard are Shaanxi Fiberglass General Factory, Xiangfan Jiebang Fiberglass Co., Ltd., Zhengzhou Haihong Chemical Co., Ltd., and Shenyang Dongdian Building Materials Technology Development Co., Ltd.
