Haisi yakarukwa michina yekugadzira mask muVietnam

Kubva padziviriro yedenda, kupa uye kudiwa kwezvinhu zvekudzivirira zvakaita semasiki, zvipfeko zvekudzivirira, magogi, uye infrared thermometers zvave zvakaoma. Meltblown PP jira risiri rakarukwa chinhu kiyi mbishi zvinhu zvemasiki uye zvipfeko zvekudzivirira zvekurapa. Nekuwedzera kwevagadziri vemasiki, zvipfeko zvekudzivirira uye zvimwe zvinhu zvekudzivirira denda, kudiwa kwezvinhu zvakakura zvakare. Vagadziri vazhinji vakatombochema-chema, "Ndine muchina wemasiki, asi hapana jira rakanyunguduka."

Sei jira rakanyungudutswa rakaoma kudaro kuwana?
Zvinonzwisiswa kuti makambani mazhinji epamba ane ruzivo mumitsara yekugadzira machira akanyunguduka asina kurukwa, asi mutengo wemidziyo yavo yekugadzira uchiri wakakwira, uye makambani akajairwa haagone kuronga nekuisa mukugadzira nekukasira, kusiyana nekugadzirwa kweotomatiki kwemaski michina. kuronga mutsara. Jira rakanyungudika rinonetsa kuwana nekuda kwekupihwa kwezvinhu, mitsetse mishoma yekugadzira michina, yakaderera kubuda, kunonoka kutangazve basa, uye kudiwa kwakanyanya. Panyaya yezvigadzirwa, Daun, Shengjin, Basel chete, nezvimwewo ndivo vaizvipa Mutambo weChirimo usati wasvika.
 Mumazuva achangopfuura, vagadziri vazhinji vepamba vakagadziridzwa vakaita saKingfa vakatangisawo melt-blown yakagadziridzwa zvinhu, izvo zvinogona kuderedza kushomeka kwekupa kune imwe nhanho. Nekudaro, mitsetse yekugadzira inonyungudika yevazhinji vagadziri inogona kupa zvinhu muhurongwa hwematani mazuva ese. Kupihwa kwevazhinji vakanyunguduka PP vanogadzira machira asiri akarukwa ari pasi pematani matatu, uye hakuna akawanda mabhizinesi makuru.
Zhejiang Yanpeng Nonwoven Machinery Co., Ltd., inova inyanzvi yekugadzira inyanzvi mukutsvagisa zvakare uye kusimudzira mitsara yekugadzira isina-yakarukwa kwemakore anopfuura gumi nemashanu, PP spunbond nonwoven kugadzira mutsara ndiyo yakakosha zvigadzirwa zvekambani yedu, uye mutsara wekugadzira. (zvakadai seS, SS, SSS ... etc) inogona kugadzira jira risiri rakarukwa rinova zvinhu zvemabhegi asina kurukwa.
Kubva iyo American Exxon Company (EXXON) yakatengesa tekinoroji yakanyunguduka muma1960s, tekinoroji yekunyungudika yakanyungudika yakagadzira nekukurumidza. Melt-blown nonwovens anogona kugadzirwa kuti azadzise anodiwa kusefa mabasa. Naizvozvo, kunyungudutswa-kuvhuvhuta nonwovens kunogona Kupfapfaidza mafirita zvigadzirwa zvinogona kutsiva zvakarongeka zvinhu zvechinyakare munzvimbo dzakasiyana.
Iwo ultrafine fibers (0.015den) yekunyunguduka-inoputika nonwovens uye matatu-dimensional labyrinth chimiro chakaumbwa nefiber 'self-adhesion uye kupinzwa muchadenga zvakasiyana zvachose nekugoverwa kwefiber mumachira echinyakare uye nemakadhi asina kuruka. Sprayed nonwovens ane hunhu hweakakura chaiwo nzvimbo, yakakwirira porosity (≥80%), akapfava voids (pore dhayamita ≤1μm), uye yakanakisa kusefa kuita kwakakwira zvakanyanya kupfuura zvimwe zvakajairwa sefa zvinhu.
Pamusoro pezvo, haasi ese machira akanyunguduka asina kurukwa akakodzera kushandiswa sesefa layer iri pakati pekuchengetedzwa kwegiredhi rekurapa. Chete electret yakanyunguduka-yakavhuvhuta isina-yakarukwa machira anogona kuwana imwe filtration kunyatsoita.
