Gulu la ntchito za magalimoto laminated nonwoven zipangizo

Zosefera zamagalimoto

Pazosefera zamagalimoto, ofufuza oyambilira adagwiritsa ntchito nsalu zonyowa zosalukidwa, koma kusefera kwawo konse kunali kotsika. Kapangidwe ka mauna atatu-dimensional endows singano yokhomeredwa ndi zinthu zopanda nsalu zokhala ndi porosity yayikulu (mpaka 70% ~ 80%), kuchuluka kwakukulu, komanso kusefera kwakukulu, kuzipanga kukhala zofunikira zopangira zida zosefera zamagalimoto. LAWRENCE et al. [10] kuwongolera kusefera kwa singano zokhomedwa ndi nsalu zopanda nsalu pochepetsa kukula kwa pore ndi tinthu tating'onoting'ono pamtunda kudzera munjira zokutira ndi zokutira. Choncho, ntchito luso laminating akhoza kwambiri kusintha kusefera dzuwa la singano kukhomerera zipangizo nonwoven.

CHEN ndi al. wokutira wosanjikiza wa thermoplastic polyurethane pa singano kukhomerera nsalu nonwoven kusintha makina ndi kukana lawi la TPU TACHIMATA singano kukhomerera nonwoven zinthu. Sun Hui et al. anakonza mitundu iwiri ya singano kukhomerera nsalulaminated kompositi zipangizo, pogwiritsa ntchito mtundu woyambirira ndi polyethylene wakuda ngati zida zokutira, ndikusanthula mawonekedwe ang'onoang'ono ndi akulu azinthu zophatikizika. Zotsatira za kafukufukuyu zikuwonetsa kuti kukonza zokutira kumatha kuwongolera crystallinity ya polyethylene yamtundu woyamba ndikulimbikitsa mawonekedwe amakina a nsanjika.

Zida zoteteza magalimoto

Spunbond nonwoven nsaluzakhala zopangira zopangira zodzitetezera zamagalimoto chifukwa cha zabwino zake zambiri. Zhao Bo adayesa zamakina, kupuma, kutulutsa chinyezi, komanso kukhazikika kwamitundu ingapo ya nsalu zingapo za laminated spunbond, ndipo adapeza kuti kupuma komanso kutsekemera kwachinyontho kwa zida za laminated spunbond nonwoven zidachepa. Chifukwa chake, zokutirazi zimakhala ndi madzi komanso osagwira mafuta pazinthu za spunbond, ndipo zimakhala ndi zotsatira zabwino kwambiri pakugwiritsa ntchito mkati mwagalimoto, kusefera, ndi kuyika.

Chifukwa cha kuchuluka kwa ndalama zomwe munthu amapeza komanso momwe amagwiritsira ntchito, mabanja ochulukirachulukira amakhala ndi magalimoto, zomwe zikuchititsa kusowa kwa malo oimika magalimoto a mabanja m'mizinda. Magalimoto ambiri amayenera kuyimitsidwa panja, ndipo pamwamba pa magalimoto amakokoloka mosavuta kapena kuwonongeka. Zovala zamagalimoto ndizinthu zotetezera zomwe zimaphimba kunja kwa thupi la galimoto, zomwe zimapereka chitetezo chogwira ntchito pagalimoto. Zovala zamagalimoto, zomwe zimadziwikanso kuti zida zamagalimoto, ndi chipangizo choteteza chopangidwa ndi chinsalu kapena zinthu zina zosinthika komanso zosavala molingana ndi kukula kwagalimoto. Ikhoza kupereka chitetezo chabwino cha utoto wa galimoto ndi galasi lazenera.

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
