Uhlalutyo lwemakethi ye-2020 kunye noqikelelo
Njengoko ubhubhani wehlabathi uqhubeka usasazeka kwaye uphucula,imaskis ziye zaphuhla zaba “yimali enzima” yehlabathi jikelele, kunye nemfuno yeimaskis ikhule ngokuqhushumba.Ngaphandle kokunyuka kwemfuno yehlabathi, kunzima ukwandisa ngokukhawuleza umthamo wemveliso yeimaskis.Phakathi kwabo, i-melt-spray-cloth, ebizwa ngokuba "yintliziyo" yeimaskis, iyanqongophala.Ixabiso lempahla ekrwada linyuke ngaphezu kwamaxesha angama-20 kwiinyanga ezi-2, nto leyo ebangele ukunqongophala kwamandla emveliso.imaskisUmzi-mveliso wavalwa ngenxa “yokunqongophala kwelaphu lokunyibilika” kunye noxinzelelo lweendleko.Ehlabathini lonkeimaskizingxamisekile, imeko yobhubhani kumazwe aphesheya isanwenwa, kwaye akukaziwa ukuba woyisa nini le mfazwe yokulwa nobhubhani wabantu.
Ukusuka kwimbono yekhonkco lezoshishino, ikhonkco lezoshishino ngokubanziimaskiishishini alintsonkothanga.Ukunyuka komsinga ubukhulu becala yimathiriyeli ekrwada kunye nezixhobo zokuvelisa ukuveliswa kweimaskis, i-midstream kukwenziwa kwezinto ezahlukeneyoimaskis, kunye nomlambo osezantsi kukujikeleza kweekhemesti kunye nezibhedlele.Kwinqanaba lokuqala lobhubhane, ukwenziwa kwemveliso yayiyeyona nto ingumqobo ngenxa yokunqongophala kwabasebenzi.Ngokunyuka kwemveliso, bekukho ukunqongophala kwezinto ezibonakalayo.Ngeenzame zeenkampani zepetrochemical ezinyukayo ezifana neSinopec, izixhobo zokuvelisa ezinxulumeneyo ziye zaba yeyona nto iphambili.
Ukujonga kwixabiso lemveliso yeimaskiishishini, ixabiso lemveliso yeimaskiUmzi-mveliso kwilizwe lase China wophule i-10 yeebhiliyoni zeeyuan ngo-2019. Uchatshazelwa sisibetho se-coronary pneumonia ngo-2020, izinga lokukhula kwexabiso lemveliso yezonyango.imaskis iya kwandiswa kakhulu (izinga lokukhula kulindeleke ukuba lifikelele kwi-28%), eliya kuqhuba ukukhula kwexabiso lemveliso yoshishino lonke.
Kwiintsuku ezimbalwa ezidlulileyo, intlanganiso yezinga eliphezulu ebanjwe igxininise ukuqiniswa komsebenzi "weziqinisekiso ezithandathu", ezicebise ngokukodwa ukuzinza kokuthengiswa kwempahla yeshishini.Okwangoku, uphuhliso lwezoqoqosho lujongene nemingeni emikhulu, kunye nokuqinisekisa ukubonelelwa kwekhonkco loshishino, ngokubanzi, kuthetha ukuqinisekisa ukuveliswa kwamashishini kunye nokuzinzisa ukuveliswa kweTshayina.Ngoko ke siqinisekisa ntoni "iziqinisekiso ezintandathu"?Ukuthunyelwa ngaphandle kwabathengi kubandakanyaimaskis, amayeza asindisa ubomi, iiselfowuni, kunye neemoto zinento yokwenza noqoqosho lwelizwe nendlela yokuphila yabantu.imaskis ngokwesiseko amalaphu non-elukiweyo.imaskiAmalaphu enziwe ngamalaphu angalukwanga asontiweyo asontiweyo kunye namalaphu angalukwanga anyibilikayo avela kwipolypropylene.Ngokuqhelekileyo banemigangatho emithathu.Ilaphu elinyibilikayongumaleko ophakathi.I-ultrafine fibre enombane omileyo, ukongeza ekuthinteleni amasuntswana othuli olukhulu, inokutsala uthuli olucolekileyo, ibhaktheriya kunye neentsholongwane ngentlawulo engatshintshiyo kumphezulu.Inokucoca okuqinileyo, ukukhusela kunye neempawu zokugquma kwe-thermal kwaye inokudlala indima yokubulala iintsholongwane.Ukwahlula indima yentsholongwane, i-melt-spray-laphu linokuthiwa "yintliziyo" yonyango.imaski.
Ngokwezibalo ezisuka kwiChina Industrial Textile Industry Association, iChina lelona lizwe livelisa amalaphu angalukwanga.Ngo-2018, ukuveliswa kwamalaphu angalukwanga kwakumalunga ne-5.94 yezigidi zeetoni, kodwa imveliso yamalaphu angalukwanga anyibilikayo ayephantsi kakhulu.Umthamo wonyaka wemveliso wawuziitoni ezingama-53,500, ezibalelwa kwi-1% yomthamo wokuvelisa amalaphu angalukwanga., Izahluli zebhetri kunye nezinye iimveliso.Okwangoku, imfuno yezonyangoimaskis isenamandla ngokwentelekiso, kwaye kulindeleke ukuba imveliso yamalaphu angalukwanga ifikelele kwi-6.76 yezigidi zeetoni ngo-2020.
