Momwe mungasankhire chosinthira choyenera cha spunbond nonwoven nsalu zopangira muzochitika zenizeni?

Posankha zosintha zaspunbond nonwoven nsaluzopangira, mfundo zotsatirazi ziyenera kutsatiridwa: “kuika patsogolo zofunika pazantchito → kusintha kukonzedwa/zopinga za chilengedwe → kulinganiza kugwilizana ndi mtengo wake → kupeza ziphaso zotsatiridwa,” kufananiza ndendende zofunikira za kagwiridwe ka ntchito ndi momwe zimagwiritsidwira ntchito.

Dziwani Zofunika Zazikulu za Nkhaniyi (Zindikirani Kayendetsedwe ka Ntchito ya Zosintha)

Choyamba, fotokozani zofunikira kwambiri pazochitikazo ndikuchotsa zinthu zachiwiri.

Ngati chofunikira kwambiri ndi "kukana misozi / kukana kuwonongeka": Yang'anani zinthu zolimbitsa thupi (POE, TPE) kapena ma inorganic fillers (nano-calcium carbonate).

Ngati chofunika kwambiri ndi "anti-adsorption/antistatic": Yang'anani kwambiri pa antistatic agents (carbon nanotubes, quaternary ammonium salt).

Ngati chofunika kwambiri ndi "chosabala / bakiteriya": sankhani mwachindunji antibacterial agents (silver ions, graphene).

Ngati chofunika kwambiri ndi "chokonda zachilengedwe/chowonongeka": Yang'anani kwambiri pazinthu zomwe zingawonongeke (PLA, PBA).

Ngati chofunika kwambiri ndi "choletsa moto / kutentha kwambiri": Ikani patsogolo zoletsa moto (magnesium hydroxide, phosphorous-nitrogen based).

Yendetsani zofunikira potengera tsatanetsatane wa kagwiritsidwe ntchito ka zochitikazo.

Pa zochitika zomwe zingagwiritsidwenso ntchito/zopha tizilombo mobwerezabwereza: Sankhani zosinthika, zokhalitsa (monga polyether-based antistatic agents, phosphorus-nitrogen based retardants).

Pamalo otsika kwambiri/otentha kwambiri: Sankhani zosintha zosinthira kutentha (zogwiritsa ntchito kutentha kwambiri). EVA (High-Temperature Nano-Silica)

Zochitika Zokhudza Khungu: Yang'anani patsogolo zosintha zokometsera khungu, zosakwiya pang'ono (quaternary ammonium salt, PLA blends)

Kusinthana ndi Kukonza ndi Zolepheretsa Zachilengedwe (Kupewa Kulephera Kusankha)

Kufananiza Makhalidwe Opangira Magawo

Gawo la Polypropylene (PP): Ikani patsogolo POE, TPE, ndi nano-calcium carbonate; processing kutentha oyenera 160-220 ℃, ngakhale zabwino

Gawo la Polyethylene (PE): Loyenera EVA ndi talc; pewani kusakanikirana ndi zosintha za polar (monga ma antibacterial agents)

Degradable Substrate (PLA): Sankhani PBA ndi PLA-specific agents toughening kuti mupewe kusokoneza magwiridwe antchito.

Kukwaniritsa Zachilengedwe ndi Kagwiritsidwe Ntchito

Zosefera (Ethylene Oxide / Mpweya Wotentha Kwambiri): Sankhani zosintha zosagwira kubereka (POE, nano-calcium carbonate; pewani ma organic antibacterial agents omwe amatha kuwola mosavuta)

Cold Chain / Low-Temperature Scenarios: Sankhani EVA ndi TPE yokhala ndi kulimba kwanyengo yotsika; pewani zosintha zomwe zimayambitsa kutsika kwa kutentha

Kunja / Kusungirako nthawi yayitali: Sankhani ma talc osakalamba komanso ma carbon nanotubes kuti mukhale okhazikika.

Kuyanjanitsa mogwirizana ndi mtengo (kuwonetsetsa zotheka)

Tsimikizirani kugwirizana kwa chosinthira ndi gawo lapansi.

Pewani kukhudza kusefukira kwa makonzedwe pambuyo powonjezera: Mwachitsanzo, kuchuluka kwa zodzaza zamkati zisapitirire 5%, ndipo kuchuluka kwa zosintha za elastomer zisapitirire 3%. Osapereka ntchito ya gawo lapansi loyambira: Mwachitsanzo, powonjezera zosintha za PLA ku magawo a PP, kuchuluka kwake kuyenera kuwongoleredwa pa 10% -15%, kusanja kulimba ndi kukana kutentha.

Ikani patsogolo mtengo:

Zochitika zotsika mtengo (mwachitsanzo, mapepala wamba achipatala): Sankhani zosintha zotsika mtengo monga talc, EVA, ndi magnesium hydroxide.

Zochitika zapakati mpaka-zapamwamba (monga kulongedza kwa zida zolondola, mavalidwe apamwamba): Sankhani zosintha zamphamvu kwambiri monga ma carbon nanotubes, graphene, ndi zosinthira ma ion siliva.

Zochitika zopanga misa: Yang'anani zosintha zokhala ndi ndalama zochepa zowonjezera komanso zokhazikika (mwachitsanzo, ma nano-level fillers, kuchuluka kwa 1% -3% ndikokwanira).

Tsimikizirani zofunikira za certification (kupewa zoopsa zakutsata)

Zochitika zamankhwala ziyenera kukumana ndi miyezo yofananira yamakampani.

Zida zolumikizirana / mawonekedwe a mabala: Osintha ayenera kudutsa chiphaso cha ISO. Kuyesa kwa 10993 Biocompatibility (mwachitsanzo, ayoni asiliva, PLA)

Zogulitsa Kutumiza kunja: Ziyenera kutsatira REACH, EN 13432, ndi malamulo ena (peŵani zosintha zomwe zili ndi phthalates; ikani patsogolo zoletsa moto za halogen komanso zosintha zowonongeka).

Zokhudzana ndi Chakudya (monga masampulo a swab): Sankhani zosintha zovomerezeka zamtundu wa chakudya (monga chakudya cha nano-calcium carbonate, PLA).

Zochitika Wamba ndi Zitsanzo Zosankhira (Zowonjezera Zachindunji)

Kupaka kwa Medical Sterilization Instrument Packaging (Core: Kukaniza Misozi + Kukaniza Kukaniza + Kutsatira): POE (kuwonjezera 1% -2%) + Nano-calcium Carbonate (1% -3%)

Zida Zogwiritsira Ntchito Pachipinda (Core: Antistatic + Anti-slip + Khungu): Carbon Nanotubes (0.5% -1%) + Quaternary Ammonium Salt Antistatic Agent (0.3% -0.5%)

Mapadi Azachipatala Osawonongeka (Core: Chitetezo Chachilengedwe + Kukana Kugwetsa Misozi): PLA + PBA Blend Modifier (chiwerengero chowonjezera…) 10% -15%)

Kuyika kwa katemera wozizira wocheperako (pachimake: kukana kutentha pang'ono + kupewa kusweka): EVA (3% -5%) + talc (2% -3%)

Zida zoteteza matenda opatsirana (pachimake: antibacterial + tensile mphamvu): siliva ion antibacterial agent (0.5% -1%) + POE (1% -2%)

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 pa 9 magalamu mpaka 300 magalamu.
