Uyawuqonda umgomo wenqubo ye-electrostatic polarization yezindwangu ezincibilikayo

I-N in N95 imaski imele ukungamelani namafutha, okungukuthi, ayimelani nowoyela; Inombolo imele ukusebenza kahle kokuhlunga lapho ihlolwa ngezinhlayiya ze-micron engu-0.3, futhi u-95 usho ukuthi ingahlunga okungenani u-95% wezinhlayiya ezincane ezifana negciwane lomkhuhlane, uthuli, impova, inkungu, nentuthu. Ngokufanayo namamaski okuhlinzwa ezokwelapha, uhlaka oluyinhloko lwamamaski we-N95 luqukethe izingxenye ezintathu: ungqimba oluvikela umswakama ongaphezulu, ungqimba oluphakathi lokuhlunga kanye ne-adsorption, kanye nongqimba lwesikhumba lwangaphakathi. Impahla eluhlaza esetshenziswayo yindwangu enesisindo esikhulu samangqamuzana e-polypropylene encibilika. Njengoba zonke ziyizindwangu ezincibilikisiwe, yiziphi izizathu zokuthi ukusebenza kahle kokuhlunga kungafinyeleli izinga?

Izizathu zokuhlunga okusezingeni eliphansi kwendwangu encibilikayo yemaski

Ukusebenza kokuhlunga kwendwangu engalukiwe encibilikisiwe ngokwayo empeleni kungaphansi kuka-70%. Akwanele ukuthembela kuphela kumphumela wokuvimbela umshini wenhlanganisela yefayibha enezinhlangothi ezintathu zamafiber e-meltblown ultrafine anemicu emihle, i-voids encane, kanye ne-porosity ephezulu. Uma kungenjalo, ukumane ukwandise isisindo nokuqina kwezinto kuzokwandisa kakhulu ukumelana nokuhlunga. Ngakho izinto zokuhlunga ezincibilikayo ngokuvamile zengeza amashaji e-electrostatic endwangu encibilikayo ngenqubo ye-electrostatic polarization, kusetshenziswa izindlela ze-electrostatic ukuthuthukisa ukusebenza kahle kokuhlunga, okungafinyelela ku-99.9% kuya ku-99.99%. Okusho ukuthi, ukufinyelela okujwayelekile kwe-N95 noma ngaphezulu.

Isimiso sokuncibilika kwefayibha yendwangu ephephezelayo

Indwangu encibilikisiwe esetshenziselwa imaski ejwayelekile ye-N95 ithwebula izinhlayiya ngomphumela ombaxambili wesithiyo semishini kanye ne-electrostatic adsorption. Umphumela wokuvinjelwa komshini uhlobene eduze nesakhiwo kanye nezakhiwo zezinto ezibonakalayo: lapho indwangu encibilikisiwe ishajwa yi-corona nge-voltage engamakhulu ambalwa kuya ezinkulungwaneni ezimbalwa zama-volts, imicu ihlakazeka ibe yinethiwekhi yezimbotshana ngenxa yokuhoxiswa kwe-electrostatic, futhi ubukhulu phakathi kwemicu bukhulu kakhulu kunothuli, ngaleyo ndlela yakhe isakhiwo esivulekile. Lapho uthuli ludlula ezintweni ezincibilikayo zokuhlunga, umthelela we-electrostatic awudonsi nje kuphela ngempumelelo izinhlayiya zothuli ezikhokhisiwe, kodwa futhi uthwebula izinhlayiya ezingathathi hlangothi ze-polarized ngokusebenzisa umphumela wokungeniswa kwe-electrostatic. Lapho ephakama amandla e-electrostatic wento esetshenziswayo, kulapho aphakama khona ukuminyana kokushaja kwento esetshenziswayo, lapho ithwala amaphuzu amaningi, futhi kuba namandla kakhulu umphumela we-electrostatic. Ukukhishwa kwe-Corona kungathuthukisa kakhulu ukusebenza kokuhlunga kwendwangu ye-polypropylene meltblown. Ukwengeza izinhlayiya ze-tourmaline kungathuthukisa ngempumelelo i-polarizability, kukhuphule ukusebenza kahle kokuhlunga, kunciphise ukumelana nokuhlunga, kukhuphule ukuminyana kokushaja kwe-fiber surface, futhi kuthuthukise umthamo wokushaja we-fiber web.

Ukwengeza u-6% we-tourmaline ku-electrode kunomphumela ongcono kakhulu. Izinto ezisetshenziswayo eziningi kakhulu ezingase zikhulise ukunyakaza kanye nokungathathi hlangothi kwezithwali zokushaja. I-masterbatch ene-electrified kufanele ibe ne-nanometer noma usayizi wesikali se-nanometer encane kanye nokufana. I-polar masterbatch enhle ingathuthukisa ukusebenza kokuphotha ngaphandle kokuthinta umlomo wombhobho, ithuthukise ukusebenza kahle kokuhlunga, imelane nokuwohloka kwe-electrostatic, inciphise ukumelana komoya, ikhuphule ukuminyana nokujula kokuthwebula ishaja, ikhulise amathuba okuba amanani amaningi abanjwe kuma-fiber aggregate, futhi igcine izindleko ezibanjiwe zisesimweni samandla aphansi, kwenze kube nzima ukuphunyuka ezicupheni zenkampani yenethiwekhi noma kwehliswe ukuwohloka, ngaleyo ndlela kunciphe.

Inqubo yokuncibilika kwe-electrostatic polarization

Inqubo yokuncibilika kokukhishwa kwe-electrostatic okuncibilikayo ibandakanya ukwengeza izinto ezingaphili njenge-tourmaline, i-silicon dioxide, ne-zirconium phosphate ku-PP polypropylene polymer kusengaphambili. Bese-ke, ngaphambi kokugingqa indwangu, into encibilikayo ephephethwayo ishajwa isethi eyodwa noma amaningi okukhishwa kwe-corona kusetshenziswa i-electrode efana nenaliti engu-35-50KV ekhiqizwe ijeneretha ye-electrostatic. Lapho kusetshenziswa i-voltage ephezulu, umoya ongaphansi kwephuzu yenaliti ukhiqiza i-corona ionization, okuholela ekuphumeni kokuphazamiseka kwendawo. Izithwali zokushaja zifakwa phezu kwendwangu encibilikisiwe encibilikayo ngokusebenzisa isenzo senkundla kagesi, futhi ezinye zazo zizobanjwa yisicupho sezinhlayiya zikamama ezimile, okwenza indwangu encibilikisiwe ibe yinto yokuhlunga ye-electrode. Amandla kagesi phakathi nale nqubo ye-corona aphansi kancane uma kuqhathaniswa nokukhishwa kwamandla kagesi aphezulu azungeze u-200Kv, okuholela ekukhiqizweni kwe-ozone kancane. Umthelela webanga lokushaja ne-voltage yokushaja awuzuzisi. Njengoba ibanga lokushaja likhuphuka, inani lenkokhiso ethathwe okokusebenza liyehla.

Indwangu encibilikisiwe kagesi iyadingeka

1. Isethi eyodwa yezinto zokusebenza ezincibilika ezincibilikayo

2. Electrified masterbatch

3. Amasethi amane wemishini yokukhipha i-electrostatic high-voltage

4. Imishini yokusika

Indwangu encibilikisiwe kufanele igcinwe ingangenwa umswakama futhi ingangeni manzi

Ngaphansi kwezimo zokushisa ezivamile kanye nomswakama, izinto ze-PP ezincibilikayo ezincibilika zinokuqina okuhle kakhulu kwesitoreji. Kodwa-ke, lapho isampula isendaweni enomswakama ophezulu, inani elikhulu lokulahlekelwa kwenkokhiso kwenzeka ngenxa yomphumela wesinxephezelo samaqembu e-polar kuma-molecule wamanzi kanye nezinhlayiya ze-anisotropic emkhathini ngamashaji emicu. Ukushaja kuyehla ngokunyuka komswakama futhi kuba ngokushesha. Ngakho-ke, ngesikhathi sokuthutha nokugcinwa, indwangu encibilikisiwe kufanele igcinwe ingenamanzi futhi igweme ukuthintana nezindawo ezinomswakama ophezulu. Uma ingagcinwa kahle, imaski ekhiqizwayo kusazoba nzima ukuhlangabezana nezindinganiso.

I-Dongguan Liansheng Non woven Technology Co., Ltd.yasungulwa ngoMeyi 2020. Kuyibhizinisi elikhulu lokukhiqiza indwangu engalukiwe ehlanganisa ucwaningo nentuthuko, ukukhiqiza, nokudayiswa. Ingakwazi ukukhiqiza imibala ehlukahlukene ye-PP spunbond izindwangu ezingalukiwe ezinobubanzi obungaphansi kwamamitha angu-3.2 ukusuka ku-9 amagremu kuya ku-300 amagremu.
