Pamwamba mankhwala njira sanali nsalu CHIKWANGWANI anamva

Ulusi wosalukidwa, womwe umadziwikanso kuti nsalu yosalukidwa, thonje lokhomeredwa ndi singano, nsalu yopanda singano, ndi zina zotero, imapangidwa ndi ulusi wa poliyesitala ndi ulusi wa poliyesitala. Amapangidwa kudzera muukadaulo wokhomerera singano ndipo amatha kupangidwa mosiyanasiyana, makulidwe, ndi mawonekedwe. Ulusi wosaluka umakhala ndi mawonekedwe a kukana chinyezi, kupuma, kufewa, kupepuka, kuchedwa kwa lawi, mtengo wotsika, komanso kubwezanso. Ikhoza kugwiritsidwa ntchito m'mafakitale osiyanasiyana, monga kutsekemera kwa phokoso, kutsekemera kwamafuta, filimu yotentha yamagetsi, masks, zovala, mankhwala, zipangizo zodzaza, ndi zina zotero.

Ulusi wosalukidwa wosalukidwa, makamaka nsalu zokhomeredwa ndi singano, umakhala ndi zinthu zambiri zotuluka pamwamba, zomwe sizipangitsa kuti fumbi ligwe. Pamwamba pa zinthu CHIKWANGWANI fyuluta. Chifukwa chake, ulusi wopanda nsalu umafunikira chithandizo chapamwamba. Cholinga cha mankhwala pamwamba anamva fyuluta thumba sanali nsalu fyuluta zakuthupi ndi kusintha kusefera Mwachangu ndi fumbi kuchotsa kwenikweni. onjezerani kukana kutentha, asidi ndi alkali kukana, ndi kukana dzimbiri; Chepetsani kukana zosefera ndikukulitsa moyo wautumiki. Pali njira zambiri zochizira pamwamba pa ulusi wopanda nsalu, koma nthawi zambiri zimatha kugawidwa m'njira zakuthupi kapena zamankhwala. Mu njira zakuthupi, njira yomwe imagwiritsidwa ntchito kwambiri ndi chithandizo cha kutentha. Tiyeni tione mwachidule pansipa.

Njira yochizira pamwamba yopanda ulusi womveka

Tsitsi lopsa

Ubweya woyaka uwotcha ulusi pamwamba pa ulusi wosalukitsidwa, womwe umathandiza kuyeretsa zosefera. Mafuta omwe amawotchedwa ndi petulo. Ngati kuyimba sikuyendetsedwa bwino, pamwamba pa zosefera zimatha kusungunuka mosagwirizana, zomwe sizimapangitsa kusefa kwafumbi. Choncho, kuyimba sikugwiritsidwa ntchito kawirikawiri.

Kuyika kwa kutentha

Ntchito yoyika kutentha kwa fiber yomwe siinaluke imamveka mu chowumitsira ndikuchotsa kupsinjika kotsalira pakukonza zomverera ndikupewa kupindika monga kutsika ndi kupindika kwa zinthu zosefera pakagwiritsidwe.

Kukanikiza kotentha

Hot rolling ndi njira yomwe imagwiritsidwa ntchito pochiza pamwamba pa ulusi wopanda nsalu. Pakugudubuzika kotentha, pamwamba pa ulusi wosalukidwa umamveka kukhala wosalala, wosalala, komanso wofanana mu makulidwe. Mphero zotentha zimatha kugawidwa m'magulu awiri, mpukutu atatu, ndi mitundu inayi.

Kupaka

Chithandizo cha zokutira chimatha kusintha mawonekedwe, kumverera, ndi mtundu wamkati wa ulusi wosalukidwa umamveka mbali imodzi, mbali zonse, kapena zonse.

Chithandizo cha Hydrophobic

Nthawi zambiri, ulusi wosalukidwa umakhala ndi hydrophobicity. Pamene condensation imapezeka mkati mwa chosonkhanitsa fumbi, m'pofunika kuonjezera hydrophobicity ya kumva kuti fumbi lisamamatire pamwamba pa zosefera. Ma hydrophobic agents omwe amagwiritsidwa ntchito kwambiri ndi mafuta odzola a parafini, silikoni ndi mchere wa aluminiyamu wamafuta amtundu wautali.

Kodi pali kusiyana kotani pakati pa nsalu zopanda nsalu ndi zomverera

Zolemba zamitundu yosiyanasiyana

Zopangira zopangidwa ndi zinthu zosalukidwa makamaka zimakhala ndi ulusi waufupi, ulusi wautali, ulusi wamkati wamatabwa, ndi zina zotere, zomwe zimapangidwa kudzera munjira monga kunyowetsa, kufutukuka, kuumba, ndi kuchiritsa, ndipo zimakhala ndi mawonekedwe a kufewa, kupepuka, komanso kupuma.

Nsalu yofewa imapangidwa kuchokera ku zinthu zopangira nsalu, makamaka zosakanikirana ndi ubweya waubweya, ubweya wa poliyesitala, ulusi wopangira, ndi ulusi wina. Zimapangidwa kudzera munjira monga makhadi, ma bonding, ndi carbonization. Makhalidwe a nsalu zomveka ndi zokhuthala, zofewa, komanso zotanuka.

Njira zosiyanasiyana zopangira

Non woven feeling ndi nsalu yopyapyala yopangidwa kudzera munjira monga kunyowetsa, kutupa, kupanga, ndi kuchiritsa, pomwe nsalu yomveredwa ndi nsalu yopangidwa kudzera munjira monga makhadi, bonding, ndi carbonization. Njira zopangira ziwirizi ndi zosiyana, kotero palinso kusiyana kwa thupi ndi mankhwala.

Zogwiritsa ntchito zosiyanasiyana

Zovala zopanda nsalu zimagwiritsidwa ntchito kwambiri m'mafakitale kusefera, kutsekereza mawu, kukana kugwedezeka, kudzaza, ndi zina. Mwachitsanzo, zomverera zopanda nsalu zitha kupangidwa kukhala zida zosiyanasiyana zosefera, zotengera mafuta, zida zamkati zamagalimoto, ndi zina zambiri.

Malingaliro a kampani 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.
