Product Description

2. Main technical parameters:
2.1 requirements for melting spray section of high melting finger:
2.1.1 melting index of molten spray section: 1200 ~ 1800±100g/10min
2.1.2 ash in melted spray sections: < 250ppm
2.1.3 melt spray section moisture: < 0.2%
2.2 finished product width: 380-820mm (g weight: 25 g/ m2 or above)
2.3 fusible spray fiber diameter: 1 ~ 6um
Standard output of 2.4m finished cloth: db-380mm180kg/day, db-600mm320kg/day, db-800mm420kg/day (for ordinary M melt spraying cloth above 25g/m2, the output of electret products is relatively lower than that of conventional products due to the influence of the processing capacity of electret equipment on the production speed.)
2.5m finished fabric specification: 20 ~ 70g/m2
2.6 melt-blown screw specification: 45 x 32 Φ separated type (screw) Φ 50 x 32 separated type (screw) Φ 65 x 32 separated type (screw)
