摘要： The present invention discloses a method for detackifying organic contaminants in the process of pulping and papermaking and a composition used for the same. Specifically, the invention discloses that the water circulation system of pulping and papermaking process can be provided with non-ionic cellulose ether and cationic coagulant in lower amount, through which, the deposition of organic contaminants can be inhibited under the synergistic action of pre-coagulation and detackification.

摘要： Strong, light-weight composite laminates are made by impregnating layers of paper with a cellulose nanofiber (CNF) slurry, laying the coated papers up in a plurality of layers or stack, and subjecting the stack to pressure and heat for a period of time sufficient to cause the CNF to impregnate, reinforce, and bond the paper layers into a composite. The resulting composite has impressive mechanical strength and exhibits a substantially homogeneous composition throughout its depth. The composite should have good strength to weight properties, and be recyclable or compostable.
