Nsalu yosalukidwa ndi fiber mesh yakuthupi yomwe imakhala yofewa, yopumira, imayamwa madzi bwino, yosamva kuvala, yopanda poizoni, yosakwiyitsa, ndipo imakhalabe ziwengo. Chifukwa chake, imagwiritsidwa ntchito kwambiri muzachipatala, thanzi, nyumba, magalimoto, zomangamanga ndi zina.
Njira yopangira nsalu zopanda nsalu
Njira yothetsera vutoli
Njira yosungunula ndiyo kusungunuka kwachindunji ndi kutulutsa kwazinthu za polima, kupanga jeti ya ulusi wa ultrafine, ndiyeno kukonza ulusi wosakhazikika pa mauna kupanga lamba kudzera mumphepo kapena dontho. Iyi ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popanga nsalu zopanda nsalu.
Njira ya Spunbond
Njira ya spunbond ndi nsalu yopanda nsalu yopangidwa ndi kusungunula mwachindunji ulusi wamankhwala kukhala njira yothetsera, ndiyeno kupanga makina opangira maukonde pamaneti kupanga lamba kudzera pakupaka kapena kulowetsedwa, kutsatiridwa ndi kuchiritsa ndi kumaliza. Njirayi ndi yoyenera kwa ulusi wokhala ndi utali wautali komanso wokulirapo.
Kukonzekera konyowa
Kukonzekera konyowa ndi njira yopangira nsalu zopanda nsalu pogwiritsa ntchito kuyimitsidwa kwa ulusi. Choyamba, amwaza ulusi mu kuyimitsidwa, ndiyeno konzani chitsanzo kudzera kupopera mbewu mankhwalawa, rotary screening, mauna akamaumba lamba, ndi njira zina. Kenako, amapangidwa kudzera munjira monga compaction, kutaya madzi m'thupi, ndi kulimba. Njirayi ndi yoyenera kwa ulusi wokhala ndi mainchesi ang'onoang'ono komanso utali wamfupi.
Kodi nsalu yosalukidwa imapangidwa pamwamba kapena pansi pa mpukutuwo?
Kawirikawiri, kupanga nsalu zopanda nsalu kumachitika pamwamba pa mpukutuwo. Kumbali imodzi, ndikupewa kuipitsidwa kwa fiber ndi zonyansa pa koyilo, komanso, ndikuwongoleranso bwino magawo monga kukangana ndi liwiro panthawi yopanga, kuti apeze zinthu zapamwamba zomwe sizinaluke nsalu.
Njira yeniyeni yopangira nsalu zopanda nsalu
1. Njira yeniyeni yokonzekera nsalu zosalukidwa ndi njira yosungunula:
Kupopera kwa utsi - fiber dispersion - kukopa kwa mpweya - kupanga mauna - ulusi wokhazikika - kukhazikitsa kutentha - kudula ndi kukula - zinthu zomalizidwa.
2. Njira yeniyeni yokonzekera nsalu zosalukidwa ndi njira ya spunbond:
Kukonzekera kwa mankhwala a polima - Kupanga mayankho - Kupaka kapena kulowetsedwa - Kutentha kwa kutentha - Kupanga - Kuchapa - Kuyanika - Kudula mpaka kukula - Zotsirizidwa.
3. Njira yeniyeni yokonzekera konyowa kwa nsalu zosalukidwa:
Kumasula CHIKWANGWANI - kusakaniza - kukonza zomatira njira - yopingasa mauna lamba - CHIKWANGWANI kufalitsa - mauna lamba kupanga - compaction - kuyanika - kuyanika - kupaka - calendering - kudula mpaka kutalika - chomalizidwa.
Kodi nsalu zosalukidwa zimapangidwa bwanji?
Choyamba tiyeni timvetsetse momwe ulusi umapangidwira. Ulusi wachilengedwe ndi wachilengedwe, pomwe ulusi wamankhwala (kuphatikiza ulusi wopangira ndi ulusi wopangidwa) umasungunula zinthu za polima mu zosungunulira kuti zipange zosungunulira kapena kuzisungunula pa kutentha kwambiri. Kenaka, yankho kapena kusungunula kumatulutsidwa kuchokera ku spinneret ya pampu yozungulira, ndipo mtsinje wa jet umazizira ndikukhazikika kuti upangitse ulusi woyamba, Ulusi woyambirira umayikidwa pazitsulo zofananira pambuyo pokonza kuti apange ulusi wamfupi kapena ulusi wautali womwe ungagwiritsidwe ntchito pa nsalu.
Kuluka nsalu ndi njira yopota ulusi kuti ukhale ulusi, womwe kenaka amalukidwa kukhala nsalu pogwiritsa ntchito makina oluka kapena kuluka. Nsalu zosalukidwa sizifuna kupota ndi kuwomba, ndiye zimasintha bwanji ulusi kukhala nsalu? Pali njira zambiri zopangira nsalu zosalukidwa, ndipo njira iliyonse ndi yosiyana, koma njira yayikulu imaphatikizira kupanga mauna a fiber ndi kulimbikitsa ma mesh.
Kupanga kwa intaneti kwa fiber
"Fiber networking", monga momwe dzinalo likusonyezera, amatanthauza njira yopangira ulusi kukhala mauna. Njira zodziwika bwino zimaphatikizapo maukonde owuma, maukonde onyowa, kupota maukonde, kusungunula maukonde, ndi zina zotero.
Njira zowuma ndi zonyowa zopangira ukonde ndizoyenera kupanga ukonde waufupi. Nthawi zambiri, zida zopangira ulusi zimayenera kusanjidwa kale, monga kukoka magulu akuluakulu a ulusi kapena midadada kukhala tiziduswa tating'ono kuti titayike, kuchotsa zonyansa, kusakaniza magawo osiyanasiyana a ulusi wofanana, ndikukonzekera musanapange ukonde. Njira youma nthawi zambiri imaphatikizapo kupesa ndi kusanjika ulusi womwe udakhalapo kale mu mauna a ulusi wokhuthala. Mapangidwe a mesh wonyowa ndi njira yobalalitsira ulusi waufupi m'madzi okhala ndi zowonjezera zamankhwala kuti apange slurry yoyimitsidwa, yomwe imasefedwa. Ulusi womwe umayikidwa pa mesh ya sefa upanga mauna a fiber.
Kuzungulira mu ukonde ndi kusungunula kuulutsidwa mu ukonde ndi njira zonse zopota zomwe zimagwiritsa ntchito ulusi wamankhwala kuti ulusiwo ulowe mu ukonde panthawi yopota. Kuzungulira mu ukonde ndi njira yomwe njira yopota kapena kusungunula imapopera kuchokera ku spinneret, itakhazikika ndi kutambasulidwa kuti ipange mlingo wina wa filament yabwino, yomwe imapanga ukonde wa fiber pa chipangizo cholandira. Melt blown mesh, kumbali ina, imagwiritsa ntchito mpweya wotentha kwambiri kuti itambasulire bwino kutuluka kwa spinneret, kupanga ulusi wa ultrafine womwe umaphatikizana pa chipangizo cholandirira kuti apange network ya fiber. Fiber diameter yomwe imapangidwa ndi njira yosungunula yosungunuka ndiyocheperako, yomwe imakhala yopindulitsa pakuwongolera kusefera.
Kuwonjezera fiber mesh
Fiber mesh yopangidwa ndi njira zosiyanasiyana imakhala ndi kulumikizana kwa ulusi wamkati komanso kutsika kwamphamvu, zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zosowa zogwiritsa ntchito. Choncho, ikufunika kulimbikitsidwa. Njira zolimbikitsira zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kuphatikiza mankhwala, kulumikiza matenthedwe, kulimbitsa kwamakina, etc.
Njira yolimbikitsira mankhwala: Zomatirazo zimagwiritsidwa ntchito pa mauna a fiber kudzera mu impregnation, kupopera mbewu mankhwalawa, kusindikiza ndi njira zina, ndiyeno kutenthedwa ndi kutentha kuti zisungunuke madzi ndi kulimbitsa zomatira, potero kulimbikitsa mauna a CHIKWANGWANI kukhala nsalu.
Njira yolumikizirana yotentha: Zida zambiri za polima zimakhala ndi thermoplastic, zomwe zikutanthauza kuti zimasungunuka ndikumata zikatenthedwa ndi kutentha kwina, ndiyeno zimalimbanso pambuyo pozizira. Mfundo imeneyi ingagwiritsidwenso ntchito kulimbikitsa maukonde a ulusi. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala zogwirizana ndi mpweya wotentha - kugwiritsa ntchito mpweya wotentha kutenthetsa mauna a fiber kuti akwaniritse kulimbikitsana; Kumangirira kotentha - kugwiritsa ntchito zodzigudubuza zachitsulo zotenthetsera kutenthetsa mauna a ulusi ndikugwiritsa ntchito mphamvu zina zolimbitsa mauna a ulusi polumikizana.
Chidule
Nsalu zopanda nsalu ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri ndi fiber mesh zomwe zakhala zofunikira komanso zofunika kwambiri pakupanga mafakitale amakono. Pogwiritsa ntchito njira zosiyanasiyana zopangira monga kusungunula,spunbond, ndi kukonzekera konyowa, zinthu zopanda nsalu zokhala ndi makhalidwe osiyanasiyana zingapezeke, zomwe zingathe kukwaniritsa zofunikira zamagulu osiyanasiyana pazinthu zopanda nsalu.
