Chomwe chimasungunuka ndi nsalu yopanda nsalu

Nsalu zosungunulira zosalukidwa ndi mtundu watsopano wansalu wopangidwa kuchokera ku zida zapamwamba za polima kudzera munjira monga kukonza zinthu zopangira, kusungunuka kwa kutentha kwambiri, kuumba kupopera, kuziziritsa ndi kulimba. Poyerekeza ndi miyambo singano kukhomerera sanali nsalu nsalu, Sungunulani kuwomba nsalu sanali nsalu ndi bwino ndi yunifolomu dongosolo CHIKWANGWANI, komanso kupuma ena ndi kukana madzi, kuwapanga kukhala chitukuko chofunika malangizo m'munda wa zipangizo nsalu.

Makhalidwe a Sungunulani kuwombedwa sanali nsalu nsalu

1. Kuchita bwino kwa kusefera, komwe kumatha kuletsa kufalikira kwa zinthu zovulaza monga tinthu tating'onoting'ono, mabakiteriya, ma virus, ndi zina;

2. Yofewa komanso yofewa, yokhala ndi mpweya wabwino, womasuka kuvala, komanso wopanda ziwengo;

3. Osavala osamva, osalowa madzi komanso osamva mafuta, okhala ndi moyo wautali wautumiki komanso kulimba kwambiri;

4. Zosavuta kukonza, zimatha kudula, kusoka, kukanikiza kotentha, laminating ndi mankhwala ena malinga ndi zosowa zosiyanasiyana.

Ntchito Sungunulani kuwomba sanali nsalu nsalu

Nsalu zosalukidwa zosungunulidwa zili ndi chiyembekezo chochuluka chogwiritsa ntchito, ndipo zafufuzidwa m'magawo monga chisamaliro chaumoyo, ukhondo, ndi zida zapakhomo. Magawo akuluakulu ogwiritsira ntchito ndi awa:

1. Zamankhwala ndi Zaumoyo: Nsalu zosungunula zosalukidwa zomwe zimasungunuka zimagwiritsidwa ntchito kwambiri popanga zida zodzitetezera monga masks, mikanjo ya opaleshoni, ndi zovala zodzipatula, zomwe zimatha kupatula mabakiteriya ndi ma virus, kuonetsetsa chitetezo cha ogwira ntchito zachipatala ndi odwala.

2. Zipangizo Zam'nyumba: Nsalu zosalukidwa zosungunuka zimagwiritsidwa ntchito kupanga zofunikira zatsiku ndi tsiku monga zopukuta zonyowa, zotsukira nkhope, ndi nsalu zotsuka ndi madzi abwino, osakanizidwa ndi madzi, komanso zovuta kukhetsa tsitsi, kupititsa patsogolo luso la wogwiritsa ntchito.

3. Zosefera: Nsalu zosalukidwa zosungunula zowombedwa zimatha kupangidwa kukhala zosefera mpweya, madzi, ndi mafuta, zomwe zimatha kuchotsa tinthu ting'onoting'ono mumlengalenga ndikuchepetsa mpweya woipa. Angagwiritsidwenso ntchito m'minda monga makina kusefera ndi kumwa madzi kusefera.

Nsalu zosalukidwa zosungunula zowombedwa ndi chinthu chabwino chotchinjiriza

Nsalu yosungunula yopanda nsalu imakhala ndi malo akuluakulu enieni komanso ochepa (pore kukula ≤ 20) μ m) Kuthamanga kwambiri (≥ 75%) ndi makhalidwe ena. Ngati m'mimba mwake ndi 3 μ Malo enieni a ulusi wosungunula wowombedwa ndi nsalu, wofanana ndi kachulukidwe kakang'ono ka 0.0638 dtex (okhala ndi kukula kwa 0.058 denier), amafika 14617 cm2/g, pamene m'mimba mwake ndi 15.3 μ Malo enieni omwe ali ndi ulusi wosasunthika, omwe ali ndi fiber pafupifupi 15.3 μ. kachulukidwe ka 1.65 dtex (ndi fiber size ya 1.5), ndi 2883 cm2/g yokha.

Chifukwa ang'onoang'ono matenthedwe madutsidwe wa mpweya poyerekeza ndi ulusi wamba, mpweya pores wa kusungunula kuwomba nsalu nonwoven amachepetsa matenthedwe madutsidwe ake. Kutaya kwa kutentha komwe kumafalikira kudzera mu ulusi wa nsalu yosungunula yowombedwa ndi yocheperako, ndipo kusanjikiza kwa mpweya wosasunthika pamwamba pa ulusi wambiri wa ultrafine kumalepheretsa kusinthanitsa kutentha komwe kumachitika chifukwa chakuyenda kwa mpweya, ndikupangitsa kuti ikhale yabwino yotchinjiriza komanso kutentha.

Ulusi wa polypropylene (PP) ndi mtundu wazinthu zomwe zilipo kale zokhala ndi matenthedwe otsika kwambiri. Chipinda chosungunula chosungunula chopangidwa ndi PP fiber pambuyo pa chithandizo chapadera chimakhala ndi ntchito yotchinjiriza yotentha 1.5 kuwirikiza pansi ndi ka 15 kuposa thonje wamba wamba. Zoyenera makamaka kupanga zovala za skiing, zovala zokwera mapiri, zofunda, matumba ogona, zovala zamkati zotentha, magolovesi, nsapato, ndi zina zotero. Zogulitsa zokhala ndi chiwerengero cha 65-200g / m2 zakhala zikugwiritsidwa ntchito popanga zovala zotentha kwa asilikali m'madera ozizira.

Momwe mungasinthire kusefera kwachangu kwa nsalu yosungunula yowombedwa yopanda nsalu

Sungunulani nsalu yopanda nsalu, monga zida zoyambira za masks azachipatala, kusefera kwake kumakhudza mwachindunji chitetezo cha chigoba. Pali zinthu zambiri zomwe zimakhudza kusefera kwa nsalu zosalukidwa zosungunulidwa, monga kachulukidwe ka fiber, kachulukidwe ka fiber mesh, makulidwe, ndi kachulukidwe. Monga zinthu zosefera mpweya wa masks, ngati zinthuzo zili zolimba kwambiri, ma pores ndi ang'onoang'ono, ndipo kukana kupuma kumakhala kwakukulu, wogwiritsa ntchito sangathe kutulutsa mpweya bwino, ndipo chigoba chimataya mtengo wake wogwiritsa ntchito. Izi zimafuna kuti zinthu zosefera zisamangowonjezera kusefera, komanso kuchepetsa kukana kwawo kupuma, komwe kumatsutsana pakati pa kukana kupuma komanso kusefera bwino. Njira yothandizira ma electrostatic electret ndi njira yabwino yothetsera kusagwirizana pakati pa kukana kupuma komanso kusefera bwino.

Zotchinga zamakina

Wapakati CHIKWANGWANI m'mimba mwake wa polypropylene kusungunula nsalu kuwomberedwa ndi 2-5 μ m. Tinthu kukula kuposa 5 mlengalenga μ Madontho a m amatha kutsekedwa ndi nsalu yosungunuka; Pamene m'mimba mwake fumbi labwino ndi losakwana 3 μ At m, chifukwa cha kusanjika kosasinthika kwa ulusi ndi ma interlayers mu nsalu yosungunula yosungunuka, wosanjikiza wa fiber ndi njira zambiri zokhotakhota zimapangidwa. Tinthu tating'onoting'ono tikadutsa m'njira zosiyanasiyana zokhotakhota kapena njira, fumbi labwino limakongoletsedwa pamwamba pa ulusi ndi mphamvu zosefera za van der Waals; Pamene kukula kwa tinthu ndi kuthamanga kwa mpweya kuli kwakukulu, mpweya umayandikira zinthu zosefera ndipo umayenda mozungulira chifukwa cha kutsekeka, pamene tinthu tating'onoting'ono timachoka pamtsinje chifukwa cha inertia ndikuwombana mwachindunji ndi ulusi womwe umayenera kugwidwa; Pamene tinthu kukula yaing'ono ndi otaya mlingo otsika, ndi particles diffuse chifukwa Brownian kuyenda ndi kugunda ndi ulusi kuti anagwidwa.

Electrostatic adsorption

Electrostatic adsorption imatanthawuza kugwidwa kwa tinthu tating'onoting'ono ndi mphamvu ya Coulomb ya ulusi woyimbidwa (electret) pomwe ulusi wa zinthu zosefera waperekedwa. Pamene fumbi, mabakiteriya, mavairasi, ndi particles zina kudutsa zinthu zosefera, electrostatic mphamvu osati mogwira amakopeka particles mlandu, komanso analanda anachititsa polarized ndale particles kudzera electrostatic kupatsidwa ulemu kwenikweni. Pamene mphamvu ya electrostatic ikuwonjezeka, mphamvu ya electrostatic adsorption imakhala yamphamvu.
