G128 marine diesel engine has a lot of improvements. Major improvement is done on the systems which have great effect on engine performance such as fuel system,combustion system,air intake system and cooling system. The engine carries on the feature of surviving harsh working condition while achieves low fuel consumption and emmissions of advanced domestic engine of same kind. The engine has good fuel economy at different operation condition due to wide minimum fuel consumption range,and better long-time propulsive force due to big low-end torque.| Model | G128Â Â Â Â Â Â Â Â Â Ca | G128Â Â Â Â Â Â Â Â Â ZCa | G128Â Â Â Â Â Â Â Â Â ZCa1 | G128Â Â Â Â Â Â Â Â Â ZLCa | G128Â Â Â Â Â Â Â Â Â ZLCa3 | G128Â Â Â Â Â Â Â Â Â ZLCa1 | G128Â Â Â Â Â Â Â Â Â ZLCa2 | G128Â Â Â Â Â Â Â Â Â ZLCa4 | G128Â Â Â Â Â Â Â Â Â Â Â Â Zcaf1 | G128Â Â Â Â Â Â Â Â Â ZLcaf | G128Â Â Â Â Â Â Â Â Â ZLcaf1 | G128Â Â Â Â Â Â Â Â Â ZLcaf2 | G128Â Â Â Â Â Â Â Â Â ZLcaf3 |

Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.
Mainly used to produce stearates: sodium stearate, magnesium stearate, calcium stearate, lead stearate, aluminum stearate, cadmium stearate, iron stearate, potassium stearate.
Widely used to make cosmetics, plastic cold-resistant plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerators, waterproofing agents, polishing agents, metal soaps, metal mineral flotation agents, softeners, pharmaceuticals and others Organic chemicals.
In addition, it can also be used as a solvent for oil-soluble pigments, a crayon slip agent, a wax paper polish, and an emulsifier for glyceryl stearate.
The product is used as a lubricant, defoamer and food additives in the food industry as a raw material for glyceryl stearate, sorbitan stearate, and sucrose esters. Used as the raw material of additives and the raw material of daily chemical products.
