Zosefera za polima kuti zisungunuke

Sefa yosungunula ndi chida chofunikira pakupota kothamanga kwambiri komanso kupota kokanira bwino. Izo ntchito mosalekeza kusefera wa polima amasungunula kuchotsa zosafunika ndi unmelted particles mu Sungunulani kusintha kupota ntchito ya Sungunulani. Ndipo kuonetsetsa ubwino wa kupota.

Sefa yosungunula imagwiritsidwa ntchito kusefera kosalekeza kwa polymer melt yopitilira kuchotsa zinyalala ndi tinthu tating'ono tating'onoting'ono tosungunuka, kuwongolera magwiridwe antchito a sungunuka ndikuwonetsetsa kuti kupota kwabwino. Sefa yosungunula ndi chida chofunikira kwambiri pakupota kothamanga kwambiri komanso kupota kwabwino. Zimagwira ntchito yodziwika bwino pakukulitsa moyo wa zida zopota, kukonza kagwiritsidwe ntchito ka zida ndikuwonjezera zotulutsa.

tsatanetsatane wazinthu

Popanga ma spunbonded nonwovens, pofuna kuwonetsetsa kuti njira yopota imayenda bwino komanso kuchepetsa kuchitika kwa ulusi wosweka ndi kudontha, zida ziwiri zosefera nthawi zambiri zimayikidwa. Fyuluta yoyamba (yaukali fyuluta) imayikidwa pakati pa screw extruder ndi pampu ya metering, ndipo ntchito yake yayikulu ndikusefa zonyansa zazikulu, kuti ziwonjezere nthawi yogwiritsira ntchito chipangizo chachiwiri cha fyuluta ndikuteteza mpope wa metering ndi mpope wopota. , Kuonjezera kuthamanga kumbuyo kwa extruder, potero kumathandizira kuti utsi ndi plasticization wa zinthu pa psinjika. Fyuluta yachiwiri (fine fyuluta) imayikidwa mumsonkhano wozungulira, ndipo ntchito yake yaikulu ndikusefa zonyansa zabwino, makristasi, ndi zina zotero, kuteteza kutsekedwa kwa spinneret, kuonetsetsa kuti kupota kukuyenda bwino, komanso kupititsa patsogolo khalidwe. wa fiber. Maonekedwe a zenera zosefera zimatengera mawonekedwe ndi kukula kwa spinneret, ndipo nthawi zambiri zimakhala zosefera zamakona angapo.
