Methods for producing dissolving grade pulp and microcrystalline cellulose from tobacco are provided. The methods include chemical pulping a tobacco input to form a tobacco pulp. Chemical pulping the tobacco input includes combining the tobacco input with a strong base defining a weight from about 5% to about 50% of the tobacco input, and heating the tobacco input and the strong base with an H-factor from about 500 to about 3,300. Further, the methods include bleaching the tobacco pulp to produce a dissolving grade pulp. Bleaching the tobacco pulp may include chlorination of the tobacco pulp with a chlorine dioxide solution, and caustic extraction of the tobacco pulp with a second strong base. A related tobacco-derived microcrystalline cellulose product is also provided, which can be used as a binder, a filler, and/or a texturizer in a tobacco product, such as a smokeless tobacco product.

A sacrificial glue composition comprises: a water-soluble resin, accounting for 18-40 wt % of the sacrificial glue composition; a low melting point compound, having a melting point of 90-180? C., and accounting for 2-20 wt % of the sacrificial glue composition; a foaming agent, accounting for 20-40 wt % of the sacrificial glue composition; and a residue of solvent. By the sacrificial glue composition, the problems of subsequent poor electroplating process and poor soldering of mounting on board caused by the unclean surface of the protective glue adhered on an end surface of an electronic part can be avoided, and the process efficiency and production capacity can be improved. Further, by the sacrificial glue composition, a simple mechanical force can be used to carry out rolling brushing the end surface of the passive element in the subsequent washing process, the protective glue causing the unclean surface can be removed.

The present invention relates to an adhesive aqueous composition comprising a polysaccharide or a residual fraction from a pulping process comprising polysaccharide and an amine-functional polymer. The weight ratio between the polysaccharide and the amine-functional polymer is from 1:4 to 4:1; wherein the polysaccharideis hemicellulose or gum and with proviso that the composition has a pH of 6 or less when the amine-functional polymer is chitosan.
