Quality appraisal of meltblown cloth production equipment

melt-blown fabric uses high-speed hot air flow to draw the thin stream of polymer melt extruded from the die spinneret, thereby forming ultra-fine fibers and collecting them on the condenser curtain or roller, while bonding to itself to become a melt-blown non-woven fabric.
melt-blown cloth production equipment includes melt-blown heads, automatic loading system equipment components, ultrasonic cleaning machines, air heaters, centrifugal fans, screw extruders, melt-blown web forming machines, melt-blown offline winding machines, melt-blown offline slitting machines and other key equipment.
In the case of quality appraisal of melt-blown cloth production equipment, Zhongke Testing can provide quality appraisal services for melt-blown cloth production equipment.

A court in Qingdao City entrusted our company to conduct quality analysis on the "SJ-65 melt-blown cloth equipment" involved in the case. The purpose of the quality appraisal analysis of the melt-blown cloth machine is as follows:
(1) On the "SJ-6 type melt-blown cloth equipment" involved in the case Analyze whether the filtration efficiency of the melt-blown cloth produced by "Type 5 Melt-blown Cloth Equipment" reaches 95% or above;
(2) analyze whether there are differences between the configuration of the "SJ-65 Type Melt-blown Cloth Equipment" involved and the contract agreement. The
analysis expert group conducted a discussion and comprehensive technical analysis on the relevant information, on-site investigation and test data of the "melt-blown cloth equipment" involved in the case, and made the following melt-blown cloth machine quality appraisal analysis opinions:
(1) Two sets of "melt-blown cloth equipment" involved in the case The filtration efficiency of the melt-blown cloth produced by the "melt-blown cloth equipment" is far less than 95%;
(2) The "melt-blown cloth equipment" involved in the case has differences in the "increased protection devices for motors and heating pipes", "rewinding meter counter", "color of the main engine and guard plate", and the simple hopper and the "Equipment Sales Contract".
