PP spunbond yopanda nsalu yopangira nsalu

Nsalu ya polypropylene spunbond nonwoven ndi mtundu watsopano wazinthu zopangidwa kuchokera ku polypropylene yosungunuka kudzera munjira monga kupota, kupanga mauna, kufewetsa, ndi kupanga. Nsalu ya polypropylene spunbond nonwoven imakhala ndi mawonekedwe abwino kwambiri komanso amakina, ndipo imagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, zaumoyo, ukhondo, zida zam'nyumba, ndi magalimoto.

Njira yopangira nsalu zosalukidwa kuchokera ku polypropylene: kudyetsa polima - kusungunula kutulutsa - kupanga CHIKWANGWANI - kuziziritsa kwa ulusi - kupanga ukonde - kulimbikitsa kukhala nsalu.

Kufotokozera mwatsatanetsatane njira yoyendetsera kupanga nsalu zopanda nsalu kuchokera ku polypropylene:

Sakanizani polypropylene ndi zowonjezera mofanana mu chosakanizira, ndipo onjezerani zosakanizazo ku chodyetsa mu extruder (monga twin-screw extruder). Zinthuzo zimalowa mu mapasa-screw kudzera mu feeder, zimasungunuka ndikusakanikirana mofanana ndi wononga, kutulutsa, granulated, ndi zouma kuti zipeze mapepala osakhala a nsalu zopangira; Kenako, ma pellets opangidwa ndi nsalu osalukidwa amawonjezedwa ku screw extruder imodzi kuti asungunuke ndi kusakaniza, kutulutsa, kutambasula mpweya, kuziziritsa ndi kulimba, kuyala mauna, ndi kulimbikitsa.

Kukonzekera zakuthupi

Polypropylene ndi mtundu wa banja la polyolefin, ndipo mfundo yake yowumba imatengera kusungunuka kwa ma polima. Waukulu zopangira pokonzekerapolypropylene spunbond nonwoven nsalundi polypropylene particles, kawirikawiri ndi tinthu kukula pakati 1-3 millimeters. Kuonjezera apo, zowonjezera monga cellulose ndi galasi fiber ziyenera kuwonjezeredwa, ndipo njira zopangira zapadera zimagwiritsidwa ntchito kuti zisungunuke particles mu viscous paste.Panthawi yopangira, chisamaliro chiyenera kulipidwa kusunga zouma zouma ndikupewa kusakaniza zonyansa.

Sungunulani kupota

Sungunulani kupota ndi imodzi mwazinthu zofunika kwambiri pokonzekera nsalu za polypropylene spunbond nonwoven. Ikani tinthu ta polypropylene mu hopper yodyetsera, idyetseni mu ng'anjo yosungunuka kudzera mu chotengera cholumikizira, tenthetsani kutentha koyenera, ndiyeno lowetsani makina opota. Makina opota amatulutsira polypropylene wosungunuka kukhala ma pores abwino kupanga ulusi. Panthawi imeneyi, chidwi chiyenera kulipidwa pakusintha magawo monga kutentha kwa kutentha, kuthamanga kwa extrusion, ndi kuzizira kuonetsetsa kuti ulusiwo umagwirizana komanso bwino.

Kupanga Net

Pambuyo posungunula, polypropylene imapanga ulusi wopitilira, ndipo ndikofunikira kupanga ulusiwo kukhala mauna. Kupanga mauna kumatengera njira yopangira utsi, pomwe ulusi umapopedwa pa ng'oma ndiyeno nkumathiridwa ndi njira monga kutenthetsa, kuziziritsa, ndikugudubuza kuti ziluke ulusi ndi kupanga nsalu yosalukidwa ngati kapangidwe. Panthawiyi, magawo monga kachulukidwe ka nozzle, kuchuluka kwa zomatira, ndi liwiro liyenera kuyendetsedwa moyenera kuti zitsimikizire kufanana ndi mtundu wa zomwe zamalizidwa.

Sungani velvet

Kuchepetsa ndi njira yochepetsera thupianamaliza spunbond nonwoven nsalumpaka kukula kwake. Pali mitundu iwiri ya kufewetsa: drying ndi kunyowa. Kupukuta kowuma kumachitidwa ndi kutentha kwakukulu ndi chinyezi chapamwamba, pamene shrinkage yonyowa imafuna kuwonjezera kwa chonyowa panthawi ya kuchepa. Panthawi yocheperako, chidwi chiyenera kuperekedwa pakuwongolera magawo monga kuchuluka kwa shrinkage, nthawi yochizira kutentha, ndi kutentha kuti zitsimikizire kukhazikika kwa kukula kwazinthu zomalizidwa.

Mawonekedwe okhazikika

Kupanga ndi njira yotenthetsera nsalu yopyapyala ya spunbond kuti ikhalebe ndi mawonekedwe ndi kukula kwake. Njira yopangira mawonekedwe imachitika pogwiritsa ntchito ma roller otentha, kutuluka kwa mpweya, ndi njira zina, ndikumvetsera kuwongolera magawo monga kutentha, kuthamanga, ndi kukakamiza kuonetsetsa kuti mawonekedwe okhazikika.

Kapangidwe ka nsalu ya spunbond nonwoven imaphatikizapo kukanikiza kotentha ndi kuphatikizika ndi mpweya wotentha kwambiri ukatha kuwumba. Pochita izi, nsalu yopanda nsalu imalowa m'chipinda cha mpweya wotentha, ndipo pansi pa kayendetsedwe ka mpweya wotentha kwambiri, mipata pakati pa ulusi imasungunuka, kuchititsa kuti ulusiwo ukhale wogwirizana, kuonjezera kufulumira kwawo ndi maonekedwe awo, ndipo potsirizira pake amapanga spunbond yopanda nsalu yomwe yapangidwa ndi yotentha.

Kumaliza

Njira yokhotakhota ndikugubuduza nsalu yosalukidwa yokhala ndi m'lifupi mwake ndi kutalika kwake kuti ikakonzedwe ndi kuyendetsa. Makina opukutira nthawi zambiri amagwiritsa ntchito mawonekedwe amadzimadzi amadzimadzi amadzimadzi komanso chowongolera mapulogalamu kuti agwire ntchito, chomwe chimatha kusintha magawo monga kukula ndi liwiro malinga ndi zosowa.

Kukonza

Nsalu za Spunbond zopanda nsalu ndizopangidwa ndi zinthu zambiri zomwe zingagwiritsidwe ntchito popanga mitundu yosiyanasiyana ya nsalu, zovala, masks, zosefera, ndi zina zotero. Panthawi yokonza, njira zosiyanasiyana zochizira monga kuyeretsa ndi kuyeretsa, kusindikiza ndi kudaya, kupaka filimu, ndi kupukuta zimayeneranso kukwaniritsa kusiyanasiyana kwa mankhwala ndi kusiyanitsa.

Chidule

Mayendedwe a nsalu za polypropylene spunbond nonwoven makamaka zimaphatikizapo: kukonza zinthu zopangira, kusungunula kusungunula, kupanga mauna, kufewetsa, ndi kupanga. Zina mwa izo, njira zitatu zazikuluzikulu zosungunula kusungunuka, kupanga ma mesh, ndi mapangidwe ake zimakhudza kwambiri mawonekedwe a thupi ndi makina a chinthu chomalizidwa, ndipo kuwongolera magawo awo ndikofunika kwambiri. Nsalu ya polypropylene spunbond nonwoven ili ndi ubwino wolemera pang'ono, mphamvu zambiri, komanso mpweya wabwino, ndipo ili ndi chiyembekezo chotukuka pa ntchito zamtsogolo.
