Spunbond polypropylene nsalu

Nsalu ya Oue spunbond nonwoven ndi mtundu wansalu wosawomba wopangidwa kuchokera ku ulusi wa thermoplastic polypropylene (PP) womwe umalumikizidwa pamodzi ndi njira yotentha. Njirayi imaphatikizapo kutulutsa ulusi wa PP, womwe umapota ndi kuikidwa mwachisawawa kuti apange ukonde. Ukondewo umalumikizidwa pamodzi kuti ukhale nsalu yolimba komanso yolimba.

Makhalidwe a PP adapota nsalu yopanda nsalu

Nsalu za polypropylene spunbond zosawomba zimakhala ndi mawonekedwe opepuka, kupuma, kulimba, kutsekereza madzi, odana ndi malo amodzi, komanso kuteteza chilengedwe.Nsalu ya polypropylene spunbond yopanda nsalu ndi zinthu zopepuka zomwe zimakhala ndi zolemera zopepuka komanso mphamvu zonyamula katundu. Izi zimapangitsa kukhala njira yabwino yopangira zinthu zina, zoyenera m'magawo ambiri monga zaumoyo, zinthu zapakhomo, ndi zina zotero. Panthawiyi, chifukwa chopepuka, ndizosavuta kunyamula ndikuyika.

pp spunbond amagwiritsa ntchito nsalu zopanda nsalu

PP spunbond nonwoven nsalu ali ndi ntchito zosiyanasiyana pa ulimi, kumanga, kulongedza, geotextiles, magalimoto, zipangizo kunyumba. Nsalu yopangidwa ndi spunbonded nonwoven ndi chinthu chokhala ndi chitukuko, chomwe chimagwiritsa ntchito bwino ubwino wa ulusi ngati zipangizo zothandizira zaumoyo. Ndi chotulukapo cha chikhalidwe chamakampani omwe akubwera omwe amapangidwa ndi kuphatikizika ndi kuphatikizika kwamaphunziro angapo ndi matekinoloje. Izi zikuphatikizapo mikanjo ya opaleshoni, zovala zodzitetezera, matumba ophera tizilombo, masks, matewera, nsalu zapakhomo, nsalu zopukutira, zopukutira kumaso, matawulo amatsenga, zofewa zofewa, zinthu zokongola, zotsuka, ndi nsalu zotayira.

Kumvetsetsa ndondomeko ya spin bonding

Njira yopangira spunbonding, yomwe imagwiritsidwa ntchito popanga nsalu zopanda nsalu, imaphatikizapo kutulutsa ma polima a thermoplastic, nthawi zambiri polypropylene (PP), kukhala ulusi wosalekeza. Pambuyo pake, ulusiwo umakonzedwa kuti ukhale mawonekedwe a ukonde ndikuphatikizana kuti apange nsalu yolimba, yokhalitsa. Zinthu zambiri zofunika, monga mphamvu yayikulu, kupuma, kukana madzi, komanso kukana kwamankhwala, zilipo munsalu yopangidwa ndi PP spunbond nonwoven. Uku ndiko kufotokozera mwatsatanetsatane kachitidwe ka spunbonding:

1. Kutulutsa kwa ma polima: Kutulutsa polima kudzera pa spinneret, nthawi zambiri ngati ma pellets, ndiye gawo loyamba pakuchita. Polima wosungunula amayendetsedwa mopanikizika kudzera mu timabowo tambirimbiri ta spinneret.

2. Kupota kwa ulusi: Polima imatambasulidwa ndi kuzizira pamene imatuluka mu spinneret kuti ipange ulusi womwe umapitirira. Kawirikawiri, filaments ndi awiri a 15-35 microns.

3. Kapangidwe ka ukonde: Kuti apange ukonde, ulusiwo umasonkhanitsidwa mwachisawawa pa lamba wosuntha kapena ng'oma. Kulemera kwa intaneti kumakhala 15-150 g/m².

4. Kumangirira: Kumangirira ulusi pamodzi, ukonde umakumana ndi kutentha, kupanikizika, kapena mankhwala. Njira zambiri, monga kugwirizanitsa kutentha, kugwirizanitsa mankhwala, kapena kusowa kwa makina, kungagwiritsidwe ntchito kuti akwaniritse izi.

5. Kumaliza: Pambuyo pa kugwirizanitsa, nsaluyo nthawi zambiri imasinthidwa kapena kupatsidwa mapeto kuti apititse patsogolo machitidwe ake, monga kukana madzi, kukana kwa UV.
