2020 mask musika kuongororwa uye kufanotaura
Sezvo denda repasi rose richiramba richipararira nekusimudzira,masks yakave yepasi rose "yakaoma mari", uye kudiwa kwemasks yakakura mukuputika. Pasinei nekuwanda kwekudiwa kwepasi rose, zvakaoma kukurumidza kuwedzera huwandu hwekugadziramasks. Pakati pavo, iyo yakanyunguduka-spray-jira, iyo inonzi "moyo" wemasks, iri kushomeka. Mutengo wezvigadzirwa zvakakwira wakakwira kanopfuura ka20 mumwedzi miviri, zvichikonzera kushomeka kwekugadzira.masks; Fekitari yakavharwa nekuda kwe "kushomeka kwejira rekunyungudika" uye kumanikidza kwemitengo. Globalmasks zviri kukurumidza, mamiriro edenda munyika dzemhiri kwemakungwa achiri kupararira, uye hazvisati zvazivikanwa kuti riini rekukunda muhondo iyi yekurwisa denda revanhu.
Kubva pakuona kweindasitiri cheni, iyo yakazara maindasitiri cheni yemaskindasitiri haina kuoma. Kumusoro kwemvura ndiko kunonyanya kushandiswa nemidziyo yekugadzira yekugadziramasks, pakati pemvura kugadzirwa kwakasiyana-siyanamasks, uye kuzasi ndiko kutenderera kwemishonga uye zvipatara. Muchikamu chekutanga chedenda, kugadzira ndiko kwakava dambudziko guru nekuda kwekushomeka kwevashandi. Nekuwedzera kwezvakabuda, pakanga paine kushomeka kwezvinhu zvakagadzirwa. Nekuedza kwemakambani epamusoro petrochemical akadai seSinopec, michina yekugadzira ine hukama yakava iyo hombe bhodhoro.
Tichitarisa kubva pakubuda kukosha kwemaskindasitiri, kukosha kwekubuda kwemaskindasitiri yekumainland China yatyora bhiriyoni gumi yeyuan muna 2019. Yakakanganiswa neconary pneumonia denda muna 2020, kukura kweiyo kukosha kwekubuda kwekurapa.masks ichawedzerwa zvakanyanya (yero yekukura inotarisirwa kusvika 28%), iyo inofambisa kukura kweiyo inobuda kukosha kweindasitiri yese.
Mazuva mashomanana adarika, musangano wepamusoro-soro wakaitwa wakasimbisa kusimbiswa kwebasa re "vimbiso nhanhatu", iyo yakanyatsoronga kugadzikana kwekutengesa kweketani yemabhizimisi. Parizvino, budiriro yehupfumi yakatarisana nematambudziko makuru, uye kuve nechokwadi chekugovera cheni yeindasitiri, kusvika pamwero mukuru, zvinoreva kuve nechokwadi chekugadzirwa kwemabhizinesi nekudzikamisa kugadzirwa kweChinese. Saka "zvitanhatu zvivimbiso" zvinovimbisa chii? Consumer exports kusanganisiramasks, mishonga inoponesa upenyu, nharembozha, nemotokari zvine chekuita neupfumi hwenyika nemararamiro evanhu.masks ari machira asiri akarukwa.maskmachira anoumbwa nemachira akarukwa-akasungwa asiri akarukwa uye akanyunguduka asina-akarukwa machira anogadzirwa kubva ku polypropylene. Vanowanzova nezvikamu zvitatu.Mucheka wakanyungudukandiyo yepakati. Iyo ultrafine faibha ine static magetsi, mukuwedzera kuvharira iyo yakakura guruva zvimedu, inogona zvakare kukwezva guruva rakatsetseka, mabhakitiriya uye mavhairasi kuburikidza neiyo static charge pamusoro. Iine kusefa kwakasimba, kudzivirira uye kupisa kwemafuta ekudzivirira uye inogona kuita basa rekuita sterilizing. Kuparadzanisa basa rehutachiona, melt-spray-jira rinogona kunzi "moyo" wechiremba.mask.
Zvinoenderana nehuwandu kubva kuChina Industrial Textile Industry Association, China ndiyo inogadzira pasi rose machira asina kuruka. Muna 2018, kugadzirwa kwemachira asiri akarukwa angangoita 5.94 miriyoni matani, asi kubuda kwemachira asina kuruka akanyunguduka kwakadzikira. Huwandu hwekugadzira hwepagore hwaive matani 53,500, achiverengera 1% yesimba rekugadzira remachira asiri akarukwa. , Battery separators uye zvimwe zvigadzirwa. Parizvino, kudiwa kwekurapamasks ichiri kusimba, uye zvinotarisirwa kuti kubuda kwemachira asina kurukwa kuchasvika 6.76 miriyoni matani muna 2020.
