Awiri chigawo spunbond nonwoven nsalu luso

Nsalu ziwiri zosawomba ndi nsalu yosawomba yomwe imapangidwa ndi kutulutsa zida ziwiri zosiyana zodulira kuchokera ku ma screw extruder odziyimira pawokha, kusungunuka ndi kuphatikizika kumapota ukonde, ndikuzilimbitsa. Ubwino waukulu waukadaulo wazinthu ziwiri za spunbond nonwoven ndikuti ukhoza kupanga zinthu zokhala ndi zinthu zosiyanasiyana kudzera mumitundu yosiyanasiyana yamitundu yosiyanasiyana pogwiritsa ntchito zida zosiyanasiyana, kukulitsa kwambiri danga lachitukuko chaukadaulo wa spunbond nonwoven.

Kapangidwe ndi mawonekedwe a zigawo ziwiri za spunbond fibers

Mzere wopangira magawo awiri a spunbond nonwoven umatulutsa mitundu inayi ya ulusi: mtundu wapakati pakhungu, mtundu wofananira, mtundu wa lalanje wa petal, ndi mtundu wa chilumba cha m'nyanja, kutengera magawo osiyanasiyana ozungulira. Zotsatirazi zikuwonetsa kwambiri mtundu wa chikopa chapakati ndi mtundu wofananira.

Ulusi wachikopa wa zigawo ziwiri za nsalu za spunbond

Chizindikiro chomwe chimagwiritsidwa ntchito kwambiri pazingwe zapakhungu ndi "S/C", chomwe ndi chidule cha Skin/Core mu Chingerezi. Mawonekedwe ake apakati amatha kukhala okhazikika, owoneka bwino, kapena osakhazikika.

Ulusi wapakatikati wa chikopa umagwiritsidwa ntchito kwambiri popanga zinthu zomangira kutentha, ndipo malo osungunuka a ulusi wakunja wa ulusiwo ndi wotsika kuposa wapakati. Kugwirizana kogwira mtima kungathe kupezedwa ndi kutentha kochepa ndi kupanikizika, kupatsa mankhwalawo manja abwino; Zinthu zapakati zimakhala ndi mphamvu zambiri, ndipo mphamvu ya zinthu zopanda nsalu zopangidwa ndi ulusi wamtundu wamitundu iwiri zimatha kukulitsidwa ndi 10% mpaka 25% poyerekeza ndi zinthu wamba, zomwe zimapangitsa kuti pakhale makina abwino azinthuzo. Zopangidwa ndi chikopa chapakati pazigawo ziwiri za ulusi sizingokhala ndi mphamvu zolimba, zofewa zabwino komanso zokokera, komanso zimatha kuthandizidwa pambuyo pochiza monga hydrophilic, madzi oletsa madzi komanso anti-static. Zida zomwe zimagwiritsidwa ntchito kwambiri pakuyatsa khungu/pachimake ndi monga PE/PP, PE/PA, PP/PP, PA/PET, ndi zina.

Ulusi wofanana wa nsalu za spunbond

Chizindikiro chomwe chimagwiritsidwa ntchito kwambiri pazigawo ziwiri zofananira ndi "S/S", chomwe ndi chidule cha chilembo choyamba cha mawu achingerezi akuti "Side/Side". Mawonekedwe ake apakati amatha kukhala ozungulira, osakhazikika, kapena mawonekedwe ena.
Zigawo ziwiri za ulusi wofanana nthawi zambiri zimakhala zofanana ndi polima, monga PP / PP, PET / PET, PA / PA, etc. Zida za zigawo ziwirizi zimakhala ndi zomatira zabwino. Mwa kukhathamiritsa ma polima kapena momwe zinthu ziliri, zida ziwirizi zimatha kutsika kapena kutulutsa kutsika kosiyana, kupanga mawonekedwe opindika mu ulusi, ndikupangitsa kuti chinthucho chikhale chokhazikika.

Kugwiritsa ntchito kwansalu ziwiri za spunbond nonwoven

Chifukwa cha mapangidwe osiyanasiyana ndi mawonekedwe ophatikizika a ulusi wamagulu awiri, komanso kuchuluka kosiyanasiyana kwa zigawo zake ziwiri, ulusi wamagulu awiri uli ndi mawonekedwe omwe ulusi wagawo limodzi sungakhale nawo. Izi sizimangowalola kuti azitha kuphimba kwathunthu zinthu zansalu zosalukidwa, komanso zimaperekanso zabwino m'magawo ena omwe zinthu zamba zopanda nsalu zilibe.

Mwachitsanzo, PE/PP chikopa pachimake zigawo ziwiri spunbond nonwoven nsalu imakhala yofewa komanso omasuka kumva kuposa chikhalidwe chimodzi chigawo spunbond nsalu, ndi silky yosalala sensation, kuti akhale oyenera kwambiri kupanga mankhwala amene kugwirizana mwachindunji ndi thupi la munthu. Nthawi zambiri amagwiritsidwa ntchito ngati nsalu yopangira zinthu zaukhondo za amayi ndi makanda. Komanso, awiri chigawo nonwoven nsalu angathe kuwonjezeredwa ntchito akupanga lamination, otentha anagubuduza lamination, ndi tepi kuponyera kubala zosiyanasiyana gulu mankhwala. Mukamagwiritsa ntchito kugudubuza kotentha, pogwiritsa ntchito kuchulukitsitsa kosiyanasiyana kwazinthu ziwirizi, ulusiwo umakhala wopindika wokhazikika wamitundu itatu chifukwa cha kupsinjika kwa shrinkage, zomwe zimapangitsa kuti pakhale mawonekedwe osalala komanso kukula kokhazikika kwa chinthucho.

Awiri chigawo spunbond nonwoven nsalu kupanga mzere mzere

The ndondomeko kupanga awiri chigawo sanali nsalu mzere kupanga n'chimodzimodzi ndi wanthawi zonse limodzi gawo kupanga mzere, kupatula kuti dongosolo lililonse kupota ali okonzeka ndi magawo awiri a processing zakuthupi yaiwisi, kunyamula, kuyeza, ndi kusakaniza zipangizo, wononga extruders, zosefera Sungunulani, kusungunula mapampu, kupota mapampu, ndi zipangizo zina, ndipo amagwiritsa ntchito spinning component awiri-component zigawo ziwiri. Njira yoyambira yopangira magawo awiri a spunbond ikuwonetsedwa mu chithunzi chotsatirachi.

Njira yoyambira yopanga magawo awiri a spunbond

Woyamba zigawo ziwiri spunbond kupanga mzere wa Hongda Research Institute wakhala bwinobwino anaika mu ntchito, ndi ntchito turnkey wakhala anamaliza ndi wosuta. Mzere wopangawu uli ndi mawonekedwe ofunikira monga kupanga kokhazikika komanso kothamanga kwambiri, kufanana kwazinthu zambiri, kufewa kwabwino, mphamvu yayikulu komanso kutalika kochepa.

Mzere wopangira zigawo ziwiri uli ndi kusinthasintha kwakukulu kwa ntchito. Pamene zipangizo zamagulu awiri zimakhala zosiyana, kapena pamene njira zosiyana zopota zimagwiritsidwa ntchito pazitsulo zomwezo, zomwe zimapangidwa ndi zigawo ziwiri zopanda nsalu. Pamene zigawo ziwiri zimagwiritsa ntchito zipangizo zomwezo komanso njira yomweyo, zomwe zimapangidwa ndi nsalu imodzi yokha yopanda nsalu. Zoonadi, chotsiriziracho sichingakhale njira yabwino yogwiritsira ntchito, ndipo zida ziwiri zomwe zakhazikitsidwa sizingakhale zoyenera pokonza zinthu zomwezo nthawi imodzi.

Dongguan 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.
