Abstract: A circuit board cleaning system includes a cleaning tank, an ion exchange resin column, and a pump unit. The cleaning tank accommodates a cleaning liquid and allows a circuit board to be immersed in the cleaning liquid. The cleaning liquid includes a liquid water and a hydrocarbon-based surfactant. An ion exchange resin filled in the ion exchange resin column is a basic ion exchange resin. The pump unit is configured to pump the cleaning liquid into the ion exchange resin column, and enable the cleaning liquid to pass through the ion exchange resin column. When the cleaning liquid passes through the ion exchange resin column, the basic ion exchange resin deprotonates the hydrocarbon-based surfactant. After the cleaning liquid passes through the ion exchange resin column, the cleaning liquid is returned to the cleaning tank to remove acidic residue remaining on a surface of the circuit board.

Abstract: A polyvinyl chloride synthetic leather without a foaming structure and a method for producing the same are provided. The polyvinyl chloride synthetic leather includes a base fabric layer and a top fabric layer. The top fabric layer is formed of a fabric composition that includes a polyvinyl chloride resin and a polymer plasticizer. The polymer plasticizer is formed from a dibasic acid raw material and a diol raw material through a polycondensation reaction, and is end-capped by an end-capped fatty acid. A chemical structure of the end-capped fatty acid has a long carbon chain (C8 to C22). An end of the long carbon chain has a carboxyl group, and another end thereof does not have any carboxyl group. A residual amount of the diol raw material in the polymer plasticizer is less than 300 ppm. An acid value of the polymer plasticizer is less than 1 mg KOH/g.

Abstract: A plasticizer and a method for manufacturing the plasticizer are provided. The method for manufacturing the plasticizer includes steps as follows: mixing a dicarboxylic acid, a diol, and a catalyst to form a reactant mixture; reacting the reactant mixture at a temperature ranging from 130° C. to 220° C. so as to form a semi-product; adding an endcapping alcohol into the semi-product at a temperature ranging from 205° C. to 220° C. so as to form a coarse plasticizer; purifying the coarse plasticizer under a pressure ranging from 760 Torr to 5 Torr so as to obtain the plasticizer. The dicarboxylic acid includes adipic acid. The diol includes a polyglycol and a saturated fatty alcohol. The endcapping alcohol includes isooctyl alcohol, isodecyl alcohol, or 2-propylheptanol. The dicarboxylic acid, the diol, and the endcapping alcohol have a molar ratio ranging from 1:0.6 to 0.9:0.3 to 0.6.
