Preparation process of lime for acid-resistant alkali-free boron-free glass fiber and product

The invention discloses a preparation process of lime for acid-resistant alkali-free boron-free glass fibers and a product, and relates to the field of preparation of lime and compositions thereof, the preparation process comprises the following steps: mixing limestone and fuel, preheating the mixture in a kiln at a specific temperature, then continuously adding the mixture to a certain temperature, and carrying out high-temperature calcination to obtain the lime for the acid-resistant alkali-free boron-free glass fibers. And finally, cooling. The prepared limestone is high in purity, has excellent stability and activity, shows excellent suspension stability after being dissolved in water, and can remarkably improve the strength and acid resistance of the glass fiber when being applied to the acid-resistant alkali-free boron-free glass fiber. 本发明公开了一种耐酸型无碱无硼玻纤用石灰的制备工艺及产物，涉及石灰及其组合物的制备领域，所述制备工艺包括以下步骤：将石灰石和燃料混合后，置于窑炉中在特定温度下预热，然后继续加入至一定温度进行高温煅烧，最后降温冷却即得。本发明所采用的制备的石灰石纯度高，具有优异的稳定性和活性，溶于水后表现出优秀的悬浮稳定性，将其用于耐酸型无碱无硼玻纤则可
