I-N kwi-N95 imaski imele ukunganyangeki kwioli, oko kukuthi, ayinakumelana neoli; Inani limele ukusebenza kakuhle kokucoca xa livavanywa nge-0.3 micron particles, kwaye i-95 ithetha ukuba inokucoca ngaphandle ubuncinane be-95% yamasuntswana amancinci afana nentsholongwane yomkhuhlane, uthuli, i-pollen, i-haze, kunye nomsi. Ngokufana neemaski zoqhaqho lwezonyango, esona sakhiwo siphambili seemaski ze-N95 sineenxalenye ezintathu: umaleko wobungqina bobumanzi obungaphezulu, isihluzo esiphakathi kunye nomaleko we-adsorption, kunye nomaleko wolusu lwangaphakathi. Imathiriyeli ekrwada esetyenzisiweyo yilaphu elinyibilikisiweyo le-molecular weight polypropylene meltblown. Ekubeni zonke zingamalaphu anyibilikisiweyo, zeziphi izizathu zokuba ukusebenza kakuhle kokucoca kungafikeleli umgangatho?
Izizathu zokungacoceki okukumgangatho ophantsi kwelaphu lemaski elinyibilikayo
Ukusebenza kohluzo lwelaphu elingalukwanga elinyibilikayo ngokwalo lingaphantsi kwama-70%. Akwanelanga ukuthembela kuphela kwisiphumo sesithintelo sikamatshini se-aggregates yefiber ene-dimensional-dimensional ye-meltblown ultrafine fibers enemicu emihle, i-voids encinci, kunye ne-porosity ephezulu. Ngaphandle koko, ukwandisa nje ubunzima kunye nobukhulu bezinto eziphathekayo kuya kwandisa kakhulu ukuxhatshazwa kokucoca. Ngoko ke imathiriyeli yokucoca evuthelweyo enyibilikayo yongeza iintlawulo zombane kwilaphu elivuthelweyo ngenkqubo ye-electrostatic polarization, kusetyenziswa iindlela zombane ukuze kuphuculwe ukusebenza kakuhle kokucoca, okunokufikelela kuma-99.9% ukuya kuma-99.99%. Oko kukuthi, ukufikelela kwinqanaba le-N95 okanye ngaphezulu.
Umgaqo wokuhluzwa kwefayibha evuthelweyo
Ilaphu elivuthelweyo elinyibilikayo elisetyenziselwa iimaski ezikumgangatho ongu-N95 ikakhulu libamba amasuntswana ngesiphumo esiphindwe kabini sesithintelo soomatshini kunye ne-electrostatic adsorption. Isiphumo sesithintelo somatshini sinxulumene ngokusondeleyo nolwakhiwo kunye neepropathi zezinto: xa ilaphu elinyibilikayo lihlawuliswa yi-corona ngevolthi engamakhulu aliqela ukuya kumawaka aliqela e-volts, iifibers zisasazeke kuthungelwano lweepores ngenxa yokugxothwa kwe-electrostatic, kwaye ubungakanani phakathi kwemicu bukhulu kakhulu kunothuli, ngaloo ndlela kwakheka isakhiwo esivulekileyo. Xa uthuli ludlula kwizinto ezinyibilikayo zokucoca, impembelelo ye-electrostatic ayitsali ngokufanelekileyo kuphela amasuntswana othuli oluhlawulisiweyo, kodwa ikwabamba amasuntswana angathathi hlangothi nge-electrostatic induction effect. Okukhona uphezulu amandla e-electrostatic wemathiriyeli, kokukhona iphezulu ingxinano yentlawulo yemathiriyeli, kokukhona ibiza amanqaku amaninzi, kwaye kokukhona isiphumo sombane sombane somelele. Ukukhutshwa kweCorona kunokuphucula kakhulu ukusebenza kokucoca kwelaphu le-polypropylene elinyibilikayo. Ukongeza amasuntswana e-tourmaline kunokuphucula ngokufanelekileyo i-polarizability, ukwandisa ukusebenza kakuhle kokucoca, ukunciphisa ukuxhathisa ukuhluzwa, ukwandisa ukuxinwa kwentlawulo yefiber surface, kunye nokwandisa umthamo wokugcina umrhumo wewebhu yefiber.
Ukongeza i-6% ye-tourmaline kwi-electrode inomphumo ongcono jikelele. Izinto ezininzi ezinokuthi zikwazi ukunyusa intshukumo kunye nokungathathi hlangothi kwabathwali bentlawulo. I-masterbatch ene-Electrified masterbatch kufuneka ibe ne-nanometer okanye i-micro nanometer scale size kunye nokufana. I-polar masterbatch elungileyo inokuphucula ukusebenza kokujikeleza ngaphandle kokuchaphazela umlomo, iphucule ukusebenza kakuhle kokucoca, ukuxhathisa ukuthotywa kwe-electrostatic, ukunciphisa ukuxhathisa komoya, ukonyusa ingxinano kunye nobunzulu bokubanjwa kwentlawulo, yandise amathuba okuba iintlawulo ezingakumbi zibanjelwe kwi-aggregates yefayibha, kwaye igcine imirhumo ebanjiweyo ikwimeko esezantsi yamandla, ikwenza kube nzima ukuqhwesha kwimigibe yomphathi wentlawulo okanye uthotywe, ngaloo ndlela uthothe.
Inkqubo ye-electrostatic polarization evuthelweyo
Inkqubo yokukhutshwa kwe-electrostatic enyibilikayo ibandakanya ukongeza izinto ezingaphiliyo ezifana ne-tourmaline, isilicon dioxide, kunye ne-zirconium phosphate kwi-PP polypropylene polymer kwangaphambili. Emva koko, phambi kokuqengqeleka ilaphu, imathiriyeli evuthelweyo enyibilikayo ihlawuliswa iseti enye okanye ezingaphezulu zokukhutshwa kwe-corona kusetyenziswa umbane omile okwenaliti ye-electrode engama-35-50KV eveliswa yijenereyitha yombane. Xa kusetyenziswa i-voltage ephezulu, umoya ongaphantsi kwencam yenaliti uvelisa i-corona ionization, ekhokelela ekukhutshweni kwendawo. Abathwali bentlawulo zifakwe kumphezulu welaphu elinyibilikayo elivuthelweyo ngokusebenzisa isenzo sentsimi yombane, kwaye ezinye zazo ziya kubanjiswa ngumgibe wamasuntswana omama omileyo, okwenza ilaphu elinyibilikayo livuthelwe into yokucoca i-electrode. I-voltage ngexesha lenkqubo ye-corona ingaphantsi kancinane xa ithelekiswa nokukhutshwa kwamandla ombane aphezulu malunga ne-200Kv, okukhokelela kwimveliso encinci ye-ozone. Umphumo womgama wokutshaja kunye nombane wokutshaja awunamveliso. Njengoko umgama wokutshaja ukhula, inani lentlawulo ebanjwe yimpahla liyancipha.
Ilaphu elinyibilikisiweyo elinombane liyafuneka
1. Iseti enye yezixhobo ezinyibilikayo
2. Electrified masterbatch
3. Iiseti ezine zezixhobo zokukhupha i-electrostatic discharge
4. Izixhobo zokusika
Ilaphu elinyibilikayo kufuneka ligcinwe lingenabumanzi kwaye lingangeni manzi
Phantsi kobushushu obuqhelekileyo kunye neemeko zokufuma, iPP iyanyibilika ivuthelwe izinto ezipholalisayo zinozinzo olugqwesileyo lokugcinwa kwentlawulo. Nangona kunjalo, xa isampuli ikwindawo yomswakama ophezulu, inani elikhulu lelahleko yentlawulo lenzeka ngenxa yempembelelo yembuyekezo yamaqela e-polar kwiimolekyuli zamanzi kunye neengqungquthela ze-anisotropic kwi-atmosphere kwiintlawulo kwiifibers. Intlawulo iyancipha ngokunyuka kokufuma kwaye ikhawuleza. Ngoko ke, ngexesha lokuthutha kunye nokugcinwa, ilaphu elinyibilikayo kufuneka ligcinwe lingenabumanzi kwaye ligweme ukudibanisa neendawo eziphakamileyo zokufuma. Ukuba ayigcinwanga ngokufanelekileyo, iimaski eziveliswayo kuya kuba nzima ukuhlangabezana nemigangatho.
Dongguan Liansheng Non woven Technology Co., Ltd.yasekwa ngoMeyi 2020. Lishishini elikhulu lemveliso yelaphu elingalukiweyo elidibanisa uphando nophuhliso, imveliso, kunye neentengiso. Inokuvelisa imibala eyahlukeneyo ye-PP spunbond amalaphu angalukwanga kunye nobubanzi obungaphantsi kwe-3.2 yeemitha ukusuka kwi-9 grams ukuya kwi-300 grams.
