M'dziko lamakono, kusefera kwakhala kofunika pakupanga anthu komanso moyo chifukwa cha kuipitsidwa kwa chilengedwe komwe kumachitika chifukwa cha chitukuko cha zachuma ndi chikhalidwe cha anthu. Kulekanitsidwa kwa zinthu zosasungunuka kuchokera kumadzimadzi podutsa muzinthu zaporous kumatchedwa kusefera.
Msika wosefera ndi imodzi mwamagawo omwe akukula mwachangu pamsika wa nonwovens. Kuchulukitsa kwa ogula kwa mpweya wabwino ndi madzi akumwa, komanso malamulo okhwima padziko lonse lapansi, ndizomwe zimayendetsa msika wosefera. Opanga zosefera akuyang'ana kwambiri zachitukuko chatsopano, ndalama ndi kukula m'misika yatsopano kuti atsogolere pagawo lofunika la nonwovens.
Kulekanitsa zolimba ku zakumwa kapena mpweya pogwiritsa ntchito nsalu zosefera za nsalu ndi gawo lofunikira kwambiri pazambiri zamafakitale, zomwe zimathandizira kuchulukira kwa zinthu zoyera, kupulumutsa mphamvu, kugwiritsa ntchito bwino njira, kubwezeretsanso zinthu zamtengo wapatali komanso kuwongolera kuipitsidwa konse. Mapangidwe ovuta komanso makulidwe a zida za nsalu, makamaka zolukidwa ndi zosapota, zimabwereketsa kusefa.
Sefa nsalundi njira yomwe kusefera kumachitikadi. Nsalu yosefera imayikidwa pamtunda wochepa wa mbale ya fyuluta. Pamene slurry amadyetsa m'chipinda cha fyuluta mbale, slurry amasefedwa kudzera mu nsalu zosefera. Zogulitsa zazikuluzikulu zosefera pamsika masiku ano ndizoluka komanso zosalukidwa (zomveka) zosefera. Nsalu zosefera zambiri zimapangidwa kuchokera ku ulusi wopangidwa monga poliyesitala, polyamide (nayiloni), polypropylene, polyethylene, PTFE (teflon), komanso nsalu zachilengedwe monga thonje. Zosefera ngati sing'anga yofunika fyuluta amagwiritsidwa ntchito kwambiri mu migodi, malasha, zitsulo, makampani mankhwala, kukonza chakudya ndi mafakitale ena okhudzana amene amafuna olimba-zamadzimadzi kulekana.
Ubwino wa nsalu zosefera ndizofunikira pakuwongolera magwiridwe antchito a makina osindikizira. Pofuna kutsimikizira mtundu wa nsalu zosefera, mawonekedwe a pamwamba, cholumikizira ndi mawonekedwe ndizofunikira kwambiri. Otsatsa atolankhani amtundu wamtundu amafufuza zamakampani ndikugwiritsa ntchito kwa kasitomala aliyense mozama kuti athe kukonza nsalu zosefera kuti zigwirizane ndi zosowa za kasitomala aliyense, kuchokera kuzinthu zachilengedwe kupita kuzinthu zopangidwa ndi zomverera.
Ochulukirachulukira opanga zosefera azindikira kuti kuwonetsetsa kuyankha mwachangu ndikokhutiritsa kwambiri kwa makasitomala awo. Amagwira ntchito ndi ogulitsa odalirika pafupi ndi malo ochitira msonkhano kuti atsimikizire kuti atha kupereka nsalu zosefera zomwe zimafunikira pa ntchito inayake. Kuti akwaniritse izi, opanga nsalu zambiri zosefera adayikapo ndalama zapamwamba kwambirimakina odulira laserkuchokeragalasi lagolide. Apa, mawonekedwe enieni a nsalu amapangidwa ndi mapulogalamu a CAD ndikusinthana ndi makina odula a laser kuti atsimikizire kulondola, kuthamanga komanso kutsimikizika mumtundu.
Chitsanzo cha goldenlaserJMCCJG-350400LD lalikulu mtundu CO2 laser kudula makinayapangidwa mwapadera kuti ikhale yothamanga kwambiri komanso kudula mwatsatanetsatane kwa nsalu za mafakitale. Izi laser kudula dongosolo amapereka ubwino ndithu pokonza zinthu zosasankhidwa. Kumanga kotsekedwa kwathunthu ndi kukula kwa tebulo (utali ndi m'lifupi) wa 3,500 x 4,000 mm. Kumanga kwa Rack ndi pinion pawiri pagalimoto yothamanga kwambiri komanso kuthamanga kwambiri komanso kulondola kwambiri.
Kukonzekera kosalekeza komanso kodziwikiratu pogwiritsa ntchito makina otumizira ophatikizika ndi chipangizo chodyera kuti athane ndi zinthu kuchokera pampukutu.Chida chofananira chopukutira chimalolanso kudula mu zigawo ziwiri za nsalu.
Kuphatikiza apo, njira yotentha ya laser imatsimikizira kuti m'mphepete mwake amasindikizidwa podula nsalu zopangira, motero amalepheretsa kuphulika, zomwe zimapangitsa kuti ntchito yotsatila ikhale yosavuta. Laser imathandizanso kukonza tsatanetsatane wabwino komanso kudula kwazing'ono zazing'ono zomwe sizingapangidwe ndi mipeni. Kuti mukhale ndi kusinthasintha kwakukulu, pali malo owonjezera ma modules olembera pafupi ndi laser kuti atsogolere kusoka kotsatira.
