Masks a N mu N95 amayimira osalimbana ndi mafuta, ndiye kuti, osagonjetsedwa ndi mafuta; Nambalayi imayimira kusefera kwachangu ikayesedwa ndi tinthu tating'ono ta 0.3, ndipo 95 ikutanthauza kuti imatha kusefa osachepera 95% ya tinthu tating'onoting'ono monga kachilombo ka fuluwenza, fumbi, mungu, chifunga, ndi utsi. Zofanana ndi masks opangira opaleshoni, mawonekedwe akulu a masks a N95 amakhala ndi magawo atatu: wosanjikiza wotsimikizira chinyezi, kusefa kwapakati ndi kutsatsa, komanso khungu lamkati. Zopangira zomwe zimagwiritsidwa ntchito ndi nsalu yolemera kwambiri ya polypropylene meltblown. Popeza zonse ndi nsalu zosungunuka, ndi zifukwa ziti zomwe kusefa kosakwanira sikukwaniritsa mulingo?
Zifukwa za kusakwanira bwino kwa kusefera kwa chigoba chosungunuka
Kusefedwa kwa nsalu yosalukidwa yosungunuka yokhayokha kumakhala pansi pa 70%. Sikokwanira kudalira kokha mphamvu yotchinga ya makina atatu-dimensional fiber aggregates a meltblown ultrafine ulusi wokhala ndi ulusi wabwino, ma voids ang'onoang'ono, ndi porosity yayikulu. Kupanda kutero, kungowonjezera kulemera ndi makulidwe azinthu kumawonjezera kukana kusefera. Choncho Sungunulani zidawomberedwa fyuluta zambiri kuwonjezera milandu electrostatic kuti Sungunulani kuwombeza nsalu mwa ndondomeko electrostatic polarization, ntchito njira electrostatic kusintha kusefera dzuwa, amene angafikire 99,9% kuti 99,99%. Ndiye kuti, kufika pa N95 standard kapena pamwamba.
Mfundo yosungunula zosefera za nsalu zosungunuka
Nsalu yosungunula yomwe imagwiritsidwa ntchito ngati masks wamba a N95 imagwira tinthu ting'onoting'ono kudzera pamitundu iwiri yotchinga ndi ma electrostatic adsorption. Mphamvu yotchinga yamakina imagwirizana kwambiri ndi kapangidwe kazinthu ndi zinthuzo: nsalu yosungunuka ikaperekedwa ndi corona ndi voteji mazana angapo mpaka ma volts zikwi zingapo, ulusiwo umafalikira mu netiweki ya pores chifukwa cha kuthamangitsidwa kwa electrostatic, ndipo kukula pakati pa ulusi ndi waukulu kwambiri kuposa fumbi, motero kupanga mawonekedwe otseguka. Pamene fumbi akudutsa Sungunulani kuwomba fyuluta zakuthupi, ndi electrostatic zotsatira osati bwino amakopa mlandu fumbi particles, komanso analanda polarized ndale particles kupyolera electrostatic kupatsidwa ulemu kwenikweni. Mphamvu yamagetsi yamagetsi ikakwera, kuchuluka kwa kachulukidwe kazinthuzo, kumanyamula mfundo zambiri, komanso mphamvu yamagetsi yamagetsi. Kutulutsa kwa Corona kumatha kusintha kwambiri kusefera kwa nsalu ya polypropylene meltblown. Kuonjezera tinthu tating'onoting'ono ta tourmaline kumatha kupititsa patsogolo polarizability, kukulitsa kusefera bwino, kuchepetsa kukana kusefera, kukulitsa kachulukidwe ka fiber pamwamba, ndikuwonjezera mphamvu yosungira pa intaneti.
Kuwonjezera 6% tourmaline ku electrode kumakhala ndi zotsatira zabwinoko. Zambiri zopangira polarization zimatha kuwonjezera kusuntha ndi kusalowerera ndale kwa zonyamulira. Electrified masterbatch iyenera kukhala ndi nanometer kapena micro nanometer sikelo ndi kufanana. Good polar masterbatch imatha kusintha magwiridwe antchito osakhudza mphuno, kukulitsa kusefera kwachangu, kukana kuwonongeka kwa electrostatic, kuchepetsa kukana kwa mpweya, kukulitsa kachulukidwe ndi kuya kwachiwombankhanga, kuonjezera mwayi wa zolipiritsa zomwe zatsekeredwa mumagulu a ulusi, ndikusunga zolipiritsa zomwe zagwidwa m'malo otsika mphamvu, kupangitsa kuti zikhale zovuta kuthawa misampha yonyamula katundu kapena kutsika pang'onopang'ono.
Sungunulani kuwombedwa kwa electrostatic polarization process
Njira yosungunula yotulutsa ma electrostatic discharge imaphatikizapo kuwonjezera zinthu zakuthupi monga tourmaline, silicon dioxide, ndi zirconium phosphate ku PP polypropylene polima pasadakhale. Kenako, asanagubuduze nsaluyo, zinthu zomwe zimasungunuka zimayimbidwa ndi seti imodzi kapena zingapo zotulutsa korona pogwiritsa ntchito singano yopangidwa ndi ma elekitirodi a 35-50KV opangidwa ndi jenereta yamagetsi. Mphamvu yamagetsi ikagwiritsidwa ntchito, mpweya womwe uli pansi pa singano umatulutsa ionization ya corona, zomwe zimapangitsa kuti pakhale kutulutsa kwapanyumba. The zonyamulira mlandu waikamo pamwamba pa Sungunulani kuwombedwa nsalu mwa zochita za kumunda magetsi, ndipo ena a iwo adzakhala msampha wa mai particles mayi, kupanga Sungunulani kuwomba nsalu zinthu fyuluta kwa elekitirodi. Mphamvu yamagetsi panthawiyi ya corona imakhala yotsika pang'ono poyerekeza ndi kutulutsa komwe kumakhala ndi mphamvu yayikulu yozungulira 200Kv, zomwe zimapangitsa kuti ozoni achepe. Zotsatira za mtunda wa kulipiritsa ndi voteji yacharge ndizotsutsana. Pamene mtunda wolipira ukuwonjezeka, kuchuluka kwa ndalama zomwe zimagwidwa ndi zinthu zimachepa.
Nsalu yosungunuka yamagetsi ndiyofunika
1. Gulu limodzi la zida zosungunulira
2. Electrified masterbatch
3. Ma seti anayi amagetsi apamwamba kwambiri otulutsa ma electrostatic discharge
4. Zida zodulira
Nsalu zosungunuka zimayenera kusungidwa kuti zisagwe chinyezi komanso madzi
Pansi pa kutentha ndi chinyezi, PP zosungunula zowombedwa ndi mpweya zimakhala ndi kukhazikika kosungirako. Komabe, pamene chitsanzo ndi mkulu chinyezi chilengedwe, kuchuluka kwa malipiro imfa ikuchitika chifukwa cha malipiro zotsatira za magulu polar mu mamolekyu madzi ndi particles anisotropic mu mlengalenga pa milandu pa ulusi. Mtengowo umachepa ndi chinyezi chochulukirapo ndipo umakhala wothamanga. Choncho, panthawi yoyendetsa ndi kusungirako, nsalu yosungunuka iyenera kusungidwa ndi chinyezi ndikupewa kukhudzana ndi malo omwe ali ndi chinyezi. Ngati sichisungidwa bwino, masks opangidwa amakhalabe ovuta kukwaniritsa miyezo.
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.
