Kumvetsetsa Njira Yokhomerera Nangano mu Nonwoven Fabric Production

Nsalu zopanda nsalundi mtundu wa zinthu zomwe zimapangidwa mwa kulumikiza kapena kulumikiza ulusi pamodzi popanda kuwomba kapena kuluka. Njirayi imapanga nsalu yolimba, yokhazikika, komanso yosunthika, yomwe imapangitsa kuti ikhale yoyenera pa ntchito zosiyanasiyana. Chimodzi mwazinthu zofunika kwambiri popanga nsalu zopanda nsalu ndi singano, yomwe imagwira ntchito yofunika kwambiri popanga.

Singano zomwe zimagwiritsidwa ntchito popanga nsalu zopanda nsalu zimapangidwira mwapadera kuti azilumikiza kapena kumangirira ulusi kuti apange ukonde wogwirizana. Masingano amenewa nthawi zambiri amapangidwa ndi chitsulo chapamwamba kwambiri ndipo amabwera m'mawonekedwe ndi makulidwe osiyanasiyana kuti agwirizane ndi mitundu yosiyanasiyana ya ulusi ndi njira zopangira. Mapangidwe a singano, kuphatikizapo mawonekedwe ake, geji, ndi kamangidwe ka minga, amapangidwa mosamala kuti akwaniritse zinthu zenizeni za nsalu monga mphamvu, kachulukidwe, ndi kapangidwe kake.

Njira yokhomerera singano, yomwe imadziwikanso kuti kuboola singano, ndi njira yodziwika bwino yopangira nsalu zopanda nsalu. Panthawi imeneyi, ulusiwo umalowetsedwa m’makina momwe umadutsa masingano angapo omwe amawakhomerera mobwerezabwereza, zomwe zimapangitsa kuti ulusiwo ugwirizane ndi kupanga ukonde wogwirizana. Kachulukidwe ndi mphamvu ya nsaluyo imatha kuwongoleredwa posintha kachulukidwe ka singano, kuzama kolowera, ndi nkhonya pafupipafupi.

Njira yokhomerera singano imasinthasintha kwambiri ndipo imatha kugwiritsidwa ntchito ndi ulusi wambiri, kuphatikiza ulusi wachilengedwe monga thonje ndi ubweya, komanso ulusi wopangidwa monga poliyesitala ndi polypropylene. Kusinthasintha kumeneku kumapangitsa kuti nsalu zokhomedwa ndi singano zikhale zoyenera kugwiritsidwa ntchito mosiyanasiyana, kuphatikiza kusefera, ma geotextiles, zamkati zamagalimoto, komanso kutsekereza.

Kuphatikiza pa kukhomerera singano, singano zimagwiritsidwanso ntchito mu njira zina zopangira nsalu zopanda nsalu monga spunbonding ndi meltblowing. Mu spunbonding, ulusi wosalekeza umatuluka ndi kuikidwa pa lamba wosuntha, ndiyeno amangiriridwa pamodzi pogwiritsa ntchito kutentha, kupanikizika, ndi singano. Kusungunula kumaphatikizapo kutulutsa polima wosungunuka kudzera m'milomo yabwino kwambiri kenako kugwiritsa ntchito mpweya wothamanga kwambiri kuti uchepetse ulusiwo usanasonkhanitsidwe pa lamba wonyamulira ndikumanga pamodzi pogwiritsa ntchito singano.

Mapangidwe ndi mapangidwe a singano omwe amagwiritsidwa ntchito popanga nsalu zopanda nsalu ndizofunikira kwambiri pa khalidwe ndi ntchito ya nsalu zomwe zimapangidwira. Maonekedwe ndi masinthidwe a singano za singano, komanso matalikirana ndi mayanidwe a singano, amatha kukhudza kwambiri mawonekedwe a nsalu, monga kulimba kwamphamvu, kukana abrasion, ndi porosity.

Komanso, kusankha kwa mtundu wa singano ndi kukula kwake kumakhudzidwa ndi zofunikira zenizeni za nsalu zopanda nsalu zomwe zimapangidwa. Mwachitsanzo, singano zokongoletsedwa bwino zitha kugwiritsidwa ntchito popanga nsalu zopepuka, pomwe singano zokulirapo ndizoyenera nsalu zolemera, zolimba kwambiri.

Pomaliza, singano zimagwira ntchito yofunika kwambiri popanga nsalu zosawomba, makamaka pakupanga nkhonya za singano, kupindika, ndi kusungunula. Mapangidwe ndi mapangidwe a singanowa amapangidwa mosamala kuti akwaniritse zinthu zenizeni za nsalu, kuzipanga kukhala zigawo zofunika kwambiri popanga nsalu zapamwamba zopanda nsalu zogwiritsidwa ntchito zosiyanasiyana.
