This paper deals with a two-stage supply chain including one supplier and one purchaser. The two coordination mechanisms: traditional supply chain and vendor-managed inventory, are analyzed on their logistics cost optimization capabilities under the centralized and decentralized decision-making conditions. The conclusions are that the logistics costs are same under the centralized decision-making; vendor-managed inventory coordination mechanism is better than traditional supply chain coordination mechanism under the decentralized decision-making.

After the treatment of the ultrasound, the paper sizing agent preparation process with emulsion copolymerization of methyl methl acrylate and butylacrylate under microwave irradiation is discussed. To research the synthesis of sizing agent, the change of emulsion polymerization products of monomer conversion, particle size, and centrifugal stability were observed under types of conditions such as microwave power and dosage of emulsifiers. This synthetic method is due to use the microwave irradiation so that its response is very fast, and it can provide a new approach to prepare efficiently a paper sizing agent in the paper making.

With the development of the sugar industry, the molasses composition of sugar cane has changed greatly. Sugar cane molasses purity decreased, while the colloid and ash increased. In recent years, the deposits from the sugar cane molassesas hindered the operation in the alcohol distillation tower, and sometimes even blocked the whole process, leading to stop the distillation flow. This paper researched the components analysis of the sugar cane molasses stillage sediment in the alcohol production scale factors. It is helpful to illustrate the formation mechanism of the deposits from the sugar molassesas stillage. By the test of X-ray diffraction, scanning electron microscopy with EDX and chemical analysis，we conclude that the main components of the deposits of molassesas is calcium sulfate, it also contains a small amount of magnesium sulfate, potassium sulfate, silica and calcium carbonate et cetera.

In this paper, ions i.e. Cu2+, Pb2+and Cd2+ were absorbed by the carboxyl bagasse hemicelluloses, and the influences of pH value, adsorption time and the initial concentration of metal ion have been studied. The results show that the optimal adsorption pH values for Cu2+, Pb2+and Cd2+ are 5.5, 5.5 and 7.5, respectively. The adsorption capacity to ions Cu2+, Pb2+and Cd2+ reaches the maximum values when the adsorption time is 180 min. Net adsorption to ions Cu2+, Pb2+and Cd2+ increases with increasing the initial concentration of the metal ions. Analysis results of adsorption dynamics show that the adsorption of Cu2+, Pb2+and Cd2+ follows Ho 's Pseudo second-order kinetics linear model. It can be seen from the adsorption isothermal research that absorption of the carboxyl bagasse hemicelluloses to ions Cu2+, Pb2+and Cd2+ can be well described by the Langmuir isotherm linear model. Moreover, the theoretical values of the maximum absorption capacity qmax for ions Cu2+, Pb2+and Cd2+ were determined to be 20.28 mg/g, 82.64 mg/g and 30.58 mg/g, respectively.

In this paper, preliminary dynamics analysis of synthesis of polyamide polyamine compounds was deduced by kinetic equation. The dynamic analysis shows that the reaction of polyethylene polyamines with adipic acid belongs to typical three reactions. In the kinetic equation, the concentration of carboxyl failed to reflect the ability of provided protons that reaction system to amine.

In this paper, polyethylenepolyamine and hexanedioic acid were used in the polycondensation reaction for Polyamide-Polyamsne, which is the intermediate product that synthesis of Polyamide-Polyamsne-Epichlorohydrin. The difference and contact between polyethylenepolyamine, diethylenetriamine (DETA) and triethylenetetramine (TAPA) in the polycondensation reaction were compared. The exploration of the polycondensation reaction was discussed. The reaction between polyethylenepolyamine and hexanedioic acid was similar to the reaction between hexanedioic acid and DETA to TAPA. The appropriate conditions of polycondensation reaction were as following: The molar ratio of polyethylene polyamine and hexanedioic acid was 1:1. The polyamide-polyamine were synthesized by keeping 130 ~ 1350C for the first 30min, then increasing to 1600C and keeping for 2h. The solid content was about 50 %. And through theoretical analysis of gel, the degree of polymerization of Polyamine polyamide intermediate increases with increase the degree of reaction.

Graft copolymerization of diethylenetriamine onto bagasse celluloses was investigated with ammonium ceric nitrate as initiator in an aqueous medium. The condition of the graft copolymerization initiator concentration, the mass ratio of monomer/cellulose, reaction temperature, reaction time based on the experiment is optimized according to the zeta potential. The results showed the relative optimum process conditions were: the concentration of initiator at 36.98mmol/L, the mass ratio of the monomer and cellulose at 1:1, the reaction temperature at 70°C, and the reaction time by 3h. In addition, the graft copolymers were characterized by Fourier transform infrared spectra (FT-IR), X-ray diffraction analysis (XRD). The results showed that bagasse celluloses could be grafted with diethylenetriamine in aqueous medium.

In this paper, a sizing agent applied in papermaking was synthesized via emulsion polymerization using styrene (St), methyl acrylic acid (MAA), methyl methacrylate (MMA) and butyl acrylate (BA) as monomer. In this process, potassium persulfate (KPS) was used as a initiator and sodium lauryl sulfate (SDS) and OP-10 were used as the emulsifier or no emulsifier was used, while NB2Bwas used as a protective atmosphere for the reaction system. The product of emulsion polymerization with St and BA has a good comprehensive properties and a certain sizing effectiveness. Furthermore, the microwave irradiation could not only produce emulsions with small diametric particles but also shorten the polymerized time greatly.
