Ilaphu elitshisiweyo elinyibilikisiweyoyimathiriyeli yokucoca ephambili yemaski, emiselwa ikakhulu yindlela yokucoca yezinto zokucoca ezinyibilikayo, ezahlulwe ngokubanzi zibe ngumqobo woomatshini, ukufunxwa kwe-electrostatic kunye nonyango lwe-electret.
1. Umqobo woomatshini
Izithintelo zoomatshini zingaba ngolu hlobo lulandelayo:
A. Amathontsi anobukhulu beesuntswana ezingaphezu kwe-5um emoyeni anokuthintelwa zizinto zokucoca.
B. Xa ububanzi bothuli bungaphantsi kwe-3um, uthuli lubanjwa ngoomatshini lulwaleko lwefayibha yetshaneli egobileyo kwizinto zokucoca imaski.
C. Xa ubungakanani besuntswana kunye nesantya sokuhamba komoya zinkulu, isuntswana liyabanjwa ngenxa yokungqubana phakathi kwe-inertia kunye ne-fiber; xa isantya sesuntswana sincinci kwaye siphantsi, isuntswana liyabanjwa ngenxa yentshukumo yeBrownian echaphazela i-fiber.
2. Ukufunxwa kwe-electrostatic
Ngokwesiqhelo kwinkqubo yokuvelisa ilaphu lokutshiza elinyibilikisiweyo kuya kubakho unyango lwe-polar, ukuze ilaphu elingalukwanga elinombane omninzi, elinombane omninzi. I-electrostatic adsorption ibhekisa ekubanjweni kweebhaktheriya zothuli kunye neentsholongwane ngamandla e-coulomb yefayibha etshajiweyo xa ifayibha yezinto zokucoca itshajiwe.
Kukho iindlela ezimbini zokuphucula amandla okugcina itshaja yezinto ze-electret:
A. Ngokuphucula ubukrelekrele kunye nokuguquguquka kwezinto, ulwakhiwo lwezinto luya kutshintsha kwaye kuya kwenziwa umjelo omde nomncinci womngxuma ukuthintela ukutyibilika kwetshaja.
B. Yenza imigibe yokuhlawula ukuze ubambe i-charge ngokungenisa izongezo ezineempawu zokugcina i-charge.
3. Ukucubungula iipali ezimiyo
Isitshixo sokuphucula ukusebenza kakuhle kwesihluzo seemaski sikwindawo yokugcina izinto ezingasebenziyo ngombane (electrostatic fabrication) kwilaphu elingalukwanga elinyibilikisiweyo. Kwisantya sokuhamba kweemaski, ukuncitshiswa kwe-electrostatic akwanelanga (umzekelo, emva kwesiqingatha senyanga emva kokuba bemkile efektri). Nangona kunjalo, iimaski zonyango eziqhelekileyo zisebenza iinyanga ezi-6, ngelixa ezinye iimaski zaseJapan zisebenza iminyaka emi-3.
I-electret yelaphu elingelukiweyo eliqhushumbisiweyo libuthathaka kakhulu kumswakama ongqongileyo. Umthengi wakha wenza uvavanyo. Emva kokuba igcinwe iintsuku ezisi-7 phantsi kobushushu obuqhelekileyo kunye nomswakama ophezulu (umswakama ongaphezulu kwe-95%), amandla omphezulu weesampuli zokutshaja ze-corona ezilungileyo nezingalunganga anciphile ukuya kwi-28% kunye ne-36% yexabiso lokuqala ngokwahlukeneyo. Ngeli xesha ngenxa yelaphu elingelukiweyo eliqhushumbisiweyo linolwakhiwo oluvulekileyo, indawo ethile yomphezulu inkulu, inxibelelana ngakumbi nokusingqongileyo okungqongileyo, yenza umswakama kwindawo okuyo, igesi erhabaxa, amasuntswana atshajiweyo ahlukeneyo, afana nalawo anobuthathaka ngakumbi, kwangaxeshanye, inkqubo yokutshaja ye-corona inokuvelisa kuphela itshaja ye-ionic ephantsi, i-charge injection kwinkqubo yokutshaja uninzi lomaleko okufutshane womphezulu ibekwe kwiifayibha zomphezulu welaphu. Xa isampuli igcinwa okanye isebenza kwindawo enomswakama ophezulu, ilahleko enkulu yetshaja ibangelwa yimpembelelo yembuyekezo yamaqela e-polar kwiimolekyuli zamanzi kunye nee-heteroions emoyeni ukuya kwitshaja yomphezulu woxinzelelo oluphezulu kwifayibha. Ke ngoko, indawo enomswakama ophezulu kufuneka ithintelwe kwinkqubo yokunyibilikisa nokutshiza ukuthuthwa kunye nokugcinwa kwelaphu.
Oku kungasentla luhlalutyo lwezizathu ezithathu zokubailaphu elingalukwanga eliqhushumbisiweyoukuqinisekisa ukusebenza kakuhle kokuhluza. Ndiyathemba ukuba uza kuyithanda. Singoochwepheshaumenzi ongalukwanga oqhushumbisiweyoUkuba unayo nayiphi na imfuneko yokuthenga, nceda ungathandabuzi ukuqhagamshelana nathi ngoko nangoko. Siza kukuthumelela iisampulu simahla.
