Kusiyana pakati pa spunbond ndi meltblown

Spunbond ndi kusungunula kuphulika ndi njira ziwiri zosiyana zopangira nsalu zosalukidwa, zomwe zimakhala ndi kusiyana kwakukulu pazida zopangira, njira zopangira, magwiridwe antchito, ndi magawo ogwiritsira ntchito.

Mfundo ya spunbond ndi kusungunula kuwombedwa

Spunbond imatanthawuza nsalu yosalukidwa yomwe imapangidwa ndi kutulutsa zida za polima mumkhalidwe wosungunuka, kupopera zinthu zosungunuka pa rotor kapena nozzle, kuikokera pansi pamalo osungunuka ndikulilimbitsa mwachangu kuti lipange ulusi, kenako kulukana ndi kulumikiza ulusi kudzera mu mesh kapena electrostatics spinning. Mfundo yake ndi kutulutsa polima wosungunuka kudzera mu extruder, kenako ndikudutsa njira zingapo monga kuziziritsa, kutambasula, ndi kutambasula molunjika, pamapeto pake kupanga nsalu yopanda nsalu.

Meltblown, kumbali ina, ndi njira yotulutsira zinthu za polima kuchokera pamalo osungunuka kudzera pamphuno yothamanga kwambiri. Chifukwa cha kukhudzidwa ndi kuziziritsa kwa mpweya wothamanga kwambiri, zida za polima zimakhazikika mwachangu kukhala zida za filamentous ndikuyandama mumlengalenga, zomwe zimakonzedwa mwachilengedwe kapena zonyowa kuti zipange ukonde wabwino wa ulusi wosalukidwa. Mfundo yake ndi kupopera zinthu zotentha kwambiri zosungunuka za polima, kuzitambasula kukhala ulusi wabwino kudzera mu mpweya wothamanga kwambiri, ndi kulimba msanga kukhala zinthu zokhwima mumlengalenga, kupanga wosanjikiza wa nsalu zabwino zosalukidwa.

Zopangira zosiyanasiyana

Nsalu zosalukidwa zosalukidwa nthawi zambiri zimagwiritsa ntchito ulusi wamankhwala monga polypropylene (PP) kapena poliyesitala (PET) ngati zopangira, pomwe nsalu zosalukidwa zomwe zimasungunuka zimagwiritsa ntchito zinthu za polima pamalo osungunuka, monga polypropylene (PP) kapena polyacrylonitrile (PAN) . Spunbonding imafuna PP kukhala ndi MF ya 20-40g / min, pamene kusungunuka kumafuna 400-1200g / min.

Kuyerekeza pakati pa ulusi wosungunuka ndi ulusi wa spunbond

A. Utali wa CHIKWANGWANI – spunbond ngati ulusi, kusungunula kuwombedwa ngati ulusi waufupi

B. Mphamvu ya CHIKWANGWANI: Mphamvu ya spunbonded CHIKWANGWANI> Mphamvu ya CHIKWANGWANI yosungunuka

C. Fiber fineness: Ulusi wosungunuka ndi wabwino kuposa ulusi wa spunbond

Njira zosiyanasiyana zopangira

The processing wa spunbond sanali nsalu nsalu kumaphatikizapo kusungunuka ulusi mankhwala pa kutentha kwambiri, kuwajambula, ndiyeno kupanga dongosolo CHIKWANGWANI maukonde kudzera kuzirala ndi kutambasula; Sungunulani zowombedwa sanali nsalu nsalu ndi ndondomeko kupopera mbewu mankhwalawa chosungunula polima zipangizo mu mlengalenga kudzera mkulu-liwiro nozzle, mofulumira kuzirala ndi kutambasula iwo mu ulusi wabwino pansi pa zochita za airflow mkulu-liwiro, pamapeto pake kupanga wosanjikiza wandiweyani CHIKWANGWANI maukonde dongosolo.

Chimodzi mwamakhalidwe a nsalu zosungunula zowombedwa ndizomwe zimakhala zocheperako, nthawi zambiri zimakhala zosakwana 10nm (micrometer), ndipo ulusi wambiri umakhala ndi 1-4 rm.

Mphamvu zosiyanasiyana pamzere wonse wozungulira kuchokera pamphuno yowombedwa mpaka ku chipangizo cholandirira sizingakhale bwino (chifukwa cha kusinthasintha kwamphamvu yamphamvu yotentha komanso yothamanga kwambiri, kuthamanga ndi kutentha kwa mpweya wozizirira, ndi zina), zomwe zimapangitsa kuti pakhale kusinthasintha kwa fiber.

Kufanana kwa ulusi wa fiber mu mauna a spunbond nonwoven nsalu ndikwabwinoko kuposa ulusi wopopera, chifukwa munjira ya spunbond, mikhalidwe yozungulira imakhala yokhazikika, ndipo kusintha kwa kulemba ndi kuziziritsa kumakhala kochepa.

Kusefukira kozungulira kumasiyanasiyana. Kuzungulira kwa spunbond ndi 50-80 ℃ kuposa kupota kwa spunbond.

Kuthamanga kwa ulusi kumasiyanasiyana. Kuzungulira chakudya 6000m/mphindi, kusungunula kuwombedwa 30Km/mphindi.

Mfumu inatambasula mtunda wake koma inalephera kuugwira. Kutalika kwa 2-4 m, 10-30 cm.

Mkhalidwe wozizira ndi wokokera ndi wosiyana. Ulusi wa Spinnbond umakokedwa ndi mpweya wabwino/woipa wozizira pa 16 ℃, pomwe ma fuse amawomberedwa ndi mpweya wabwino/woipa wotentha pafupi ndi 200 ℃.

Ntchito zosiyanasiyana zamalonda

Nsalu zosalukidwa zosalukidwa nthawi zambiri zimakhala ndi mphamvu zosweka kwambiri komanso kutalika kwake, koma mawonekedwe ake komanso kufanana kwa mauna a ulusi amatha kukhala osauka, omwe amakwaniritsa zofunikira zamafashoni monga matumba ogula; Nsalu yosalukidwa yosungunuka imakhala ndi mpweya wabwino, kusefera, kukana kuvala, komanso anti-static properties, koma imatha kukhala ndi manja osamveka bwino komanso mphamvu, ndipo imatha kugwiritsidwa ntchito kupanga masks azachipatala ndi zinthu zina.

Magawo osiyanasiyana ogwiritsira ntchito

Nsalu zosalukidwa zopanda nsalu zimagwiritsidwa ntchito kwambiri muzachipatala, zovala, kunyumba, mafakitale ndi zina, monga masks, mikanjo ya opaleshoni, zophimba za sofa, makatani, ndi zina zotero; Nsalu zosungunula zosungunuka zimagwiritsidwa ntchito makamaka pazachipatala, thanzi, chitetezo, chitetezo cha chilengedwe ndi zina, monga masks apamwamba, zovala zotetezera, zosefera, ndi zina zotero.

Mapeto

Nsalu zosalukidwa zosungunuka ndi spunbond zosalukidwa ndi zida ziwiri zosiyana zosalukidwa zomwe zimakhala ndi njira zopangira komanso mawonekedwe osiyanasiyana. Pankhani ya kugwiritsa ntchito ndi kusankha, ndikofunikira kuganizira mozama za zosowa zenizeni ndi mawonekedwe a kagwiritsidwe ntchito, ndikusankha zinthu zoyenera kwambiri zomwe sizinalukidwe.
