Baking-free preparation method of honeycomb type molecular sieve
The invention discloses a baking-free preparation method of a honeycomb type molecular sieve, which comprises the following steps: S1, blending molecular sieve raw powder with a high-temperature inorganic binder to prepare a mixture a, S2, putting the mixture a into a gravity-free mixer to be mixed, stirring for 90-120 min through the gravity-free mixer, and evenly mixing so that a mixture b is prepared. The molecular sieve raw powder is mixed with the high-temperature inorganic binder in a proper proportion by using a gravity-free mixer, some modified high-plasticity clay can be added when necessary, the mixture is mixed with proper water to form a mud pie, vacuum pugging is performed, microwave drying and hot air drying are carried on the extruded honeycomb ceramic, the dried honeycomb type molecular sieve is inspected to obtain a finished product, the prepared honeycomb type molecular sieve has high compressive strength and higher compressive strength than a fired finished product,and generally, the compressive strength is not reduced at the desorption temperature of 200-350 DEG C, so that the situation that the application situation of the honeycomb type molecular sieve is limited due to the fact that the strength of the molecular sieve is relatively low is avoided.
本发明公开了蜂窝型分子筛的免烧制作方法，包括以下步骤：S1、首先将分子筛原粉与高温无机粘结剂调配，制备得混合料a；S2、将混合料a投入至无重力混合机内进行混合，无重力混合机搅拌90‑120min，达到混合均匀，制备混合料b；本发明将分子筛原粉与高温无机粘结剂以适当的比例用无重力混合机混合，必要时可添加一些改性的高可塑性黏土，再与适当的水进行混练成泥团，经过真空练泥练泥，挤出后的蜂窝陶瓷经过微波干燥和热风干燥，干燥好的蜂窝型分子筛经过检查就是成品，制备的该蜂窝型的分子筛抗压强度，比烧成品的抗压强度高，且一般情况下，于200～350℃脱附温度下抗压强度不下降，避免了分子筛的强度就比较低，从而限制了蜂窝型分子筛的应用情况。
