Njengento esemqoka yamamaski ezokwelapha, ukusebenza kahle kokuhlunga kwendwangu encibilikayo kuthinta ngqo umphumela wokuvikela wamaski. Kunezici eziningi ezithinta ukusebenza kokuhlunga kwezindwangu ezincibilikisiwe, njengokuminyana komugqa wefayibha, ukwakheka kwe-fiber mesh, ukujiya, kanye nokuminyana.
Nokho, njenge-impahla yokuhlunga umoyakumaski, uma impahla iqinile kakhulu, ama-pores mancane kakhulu, futhi ukumelana nokuphefumula kuphezulu kakhulu, umsebenzisi akakwazi ukuhogela umoya kahle, futhi imaski ilahlekelwa inani layo.
Lokhu kudinga izinto zokuhlunga hhayi nje ukuthuthukisa ukusebenza kahle kokuhlunga, kodwa futhi nokunciphisa ukumelana nokuphefumula ngangokunokwenzeka, futhi ukumelana nokuphefumula nokusebenza kahle kokuhlunga kuyipheya ephikisanayo. Inqubo yokwelashwa kwe-electrostatic polarization iyindlela engcono kakhulu yokuxazulula ukungqubuzana phakathi kokumelana nokuphefumula nokusebenza kahle kokuhlunga.
Indlela yokuhlunga yendwangu encibilikisiwe
Emshinini wokuhlunga wezinto zokuhlunga eziphephukayo, izindlela ezivame ukubonwa ikakhulukazi zihlanganisa ukusabalalisa kwe-Brownian, ukucasha, ukungqubuzana kwe-inertial, ukulungisa amandla adonsela phansi, kanye ne-electrostatic adsorption. Ngenxa yokuthi izimiso ezine zokuqala ziyizithiyo zemishini yonke, indlela yokuhlunga yezindwangu ezincibilikayo ingafinyezwa kalula njengezithiyo zemishini kanye ne-electrostatic adsorption.
Isithiyo semishini
Isilinganiso se-fiber diameter yepolypropylene meltblown indwanguingu-2-5 μ m, futhi amaconsi anosayizi wezinhlayiyana ezinkulu kuno-5 μ m emoyeni angavinjwa indwangu encibilikisiwe.
Uma ububanzi bothuli olucolekile bungaphansi kuka-3 μ m, imicu esendwangu encibilikayo ihlelwa ngokungahleliwe futhi ihlanganiswe ukuze kwakhe ungqimba lwesihlungi se-fiber egobile eningi. Lapho izinhlayiya zidlula ezinhlotsheni ezihlukahlukene zamashaneli noma ezindleleni ezigobile, uthuli olucolekileyo lukhangiswa endaweni yefayibha ngamandla omshini wokuhlunga i-van der Waals.
Uma usayizi wezinhlayiya kanye nesivinini sokugeleza komoya kokubili kukukhulu, ukugeleza komoya kusondela kumpahla yesihlungi futhi kuyavinjwa, kubangele ukuthi igeleze izungeza, kuyilapho izinhlayiya zihlehla ku-streamline ngenxa ye-inertia futhi zishayisane ngokuqondile nemicu, iyabanjwa.
Uma usayizi wezinhlayiyana mncane futhi izinga lokugeleza liphansi, izinhlayiya ziyasakazeka ngenxa yokunyakaza kwe-Brownian bese zishayisana nemicu ezobanjwa.
I-adsorption ye-electrostatic
I-electrostatic adsorption ibhekisela ekuthathweni kwezinhlayiya ngamandla e-Coulomb amafayibha ashajiwe (ama-polarizations) lapho amafayibha omsebenzi wokuhlunga eshajwa. Lapho uthuli, amabhaktheriya, amagciwane kanye nezinye izinhlayiya zidlula ezintweni zokuhlunga, amandla e-electrostatic awakwazi ukuheha kuphela izinhlayiya ezikhokhisiwe, kodwa futhi abambe izinhlayiya ezingathathi hlangothi ezenziwe nge-polarized ngokusebenzisa umphumela wokungeniswa kwe-electrostatic. Njengoba amandla e-electrostatic enyuka, umphumela we-electrostatic adsorption uba namandla.
Isingeniso Senqubo Yokufaka Ugesi Nge-Electrostatic
Ngenxa yokusebenza kahle kokuhlunga kwezindwangu ezingezona ezilukiwe ezincibilikisiwe ezingaphansi kuka-70%, ukuthembela kuphela kumphumela wokuvinjwa kwemishini wama-aggregate anezinhlangothi ezintathu zamafayibha anemicu emihle, ama-void amancane, kanye ne-porosity ephezulu ekhiqizwa imicu ye-ultrafine encibilikisiwe akwanele. Ngakho-ke, izinto zokuhlunga ezincibilikayo ngokuvamile zengeza imiphumela yokushaja ye-electrostatic kwendwangu encibilikayo ngobuchwepheshe be-electrostatic polarization, kusetshenziswa izindlela ze-electrostatic ukuze kuthuthukiswe ukusebenza kahle kokuhlunga, okwenza kube nokwenzeka ukufeza ukusebenza kahle kokuhlunga okungu-99.9% kuya ku-99.99%. Ungqimba oluncane kakhulu lungahlangabezana nezindinganiso ezilindelekile, futhi ukumelana nokuphefumula nakho kuphansi.
Njengamanje, izindlela eziyinhloko zokwenza i-electrostatic polarization zifaka i-electrospinning, ukukhishwa kwe-corona, i-polarization ebangelwa ukungqubuzana, i-thermal polarization, kanye nokuqhuma kwamabhomu e-electron beam encane. Phakathi kwazo, ukukhishwa kwe-corona njengamanje kuyindlela engcono kakhulu ye-electrostatic polarization.
Indlela yokukhipha i-corona iyindlela yokushaja into encibilikisiwe ngesethi eyodwa noma amaningi ama-electrodes amise njengenaliti (amandla kagesi ngokuvamile angu-5-10KV) wejeneretha ye-electrostatic ngaphambi kokusonga i-meltblown fiber mesh. Lapho kusetshenziswa i-voltage ephezulu, umoya ongaphansi kwephuzu yenaliti ukhiqiza i-corona ionization, okuholela ekuphumeni kokuphazamiseka kwendawo. Izithwali zifakwa ebusweni bendwangu encibilikisiwe ngaphansi kwesenzo senkundla kagesi, futhi abanye abathwali bazobanjwa izicupho zezinhlayiya zikamama ezimile ekujuleni kwendawo, okwenza indwangu encibilikisiwe ibe yinto yokuhlunga yomzimba omile.
Ukwenyusa ukushaja okungaphezulu kwendwangu encibilikisiwe kungatholwa ngendlela yokukhishwa kwe-corona yokwelashwa kokukhishwa kwe-electrostatic, kodwa ukuze kuvinjwe ukubola kwalesi sitoreji se-electrostatic, ukwakheka kanye nokwakheka kwento encibilikayo ye-electrode kudingeka ihambisane nokushaja ukugcinwa. Indlela yokuthuthukisa umthamo wokushaja wesitoreji sezinto ze-electret ingafinyelelwa ngokwethula izithasiselo ezinezakhiwo zokushaja ukuze kukhiqizwe izicupho zokushaja kanye nezindleko zokuthwebula.
Ngakho-ke, uma kuqhathaniswa nemigqa yokukhiqiza encibilikisiwe evamile, ukukhiqizwa kwezinto ezincibilikayo ezincibilikayo zokuhlunga komoya kudinga ukungezwa kwemishini yokukhishwa kwe-electrostatic ephezulu emgqeni wokukhiqiza, kanye nokwengezwa kwe-polar masterbatch efana nezinhlayiya ze-tourmaline ekukhiqizeni i-polypropylene eluhlaza (PP).
Izici eziyinhloko ezithinta umphumela wokwelashwa kwe-electrospinning ezindwangu ezincibilikayo
1. Izimo zokushaja: isikhathi sokushaja, ibanga lokushaja, i-voltage yokushaja;
2. Ukuqina ;
3. Izinto ezisebenza ngogesi.
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.
