Embodiment Construction
[0030] The production process of the spunlace composite high-temperature-resistant and corrosion-resistant filter material of the present invention uses polyphenylene sulfide fiber and glass fiber base cloth as raw materials; the polyphenylene sulfide fiber is first inspected, weighed and fed, and then fed into the long curtain in sequence , horizontal opener, large warehouse mixing box, fine opener, and then carding machine 1 and carding machine 2 perform layered carding, and then enter the cross-lapper 1 and cross-lapper 2 respectively for laying Then the glass fiber base cloth is sandwiched between the raw materials conveyed by the first cross-lapper and the second cross-lapper and laminated, and then enters the pre-wet process, spunlace process, dehydration process, and drying process in sequence. Drying process, coiling process.
[0031] Among them, carding machine one, the main cylinder work roll is 110m / min, the main cylinder stripping roll is 150m / min, the main cylinde...
