Izixhobo ezingalukwanga zokwenza imaski eVietnam

Ukusukela oko kuthintelwe ubhubhane, unikezelo kunye nemfuno yezinto ezikhuselayo ezinje ngeemaski, iimpahla ezikhuselayo, iiglasi, kunye neethermometers ze-infrared ziye zaqina. Ilaphu elingalukwanga iMeltblown PP yeyona nto iphambili ekrwada imaski kunye nempahla ekhuselayo yezonyango. Ngokunyuka kwabavelisi beemaski, iimpahla ezikhuselayo kunye nezinye izinto zokuthintela ubhubhane, imfuno yezinto ezikrwada nayo inkulu. Abavelisi abaninzi bade bakhala, "Ndinomatshini wemaski, kodwa akukho laphu linyibilikayo."

Kutheni kunzima kangaka ukufumana ilaphu elinyibilikisiweyo?
Kuyaqondwa ukuba iinkampani ezininzi zasekhaya zinamava athile kwimigca yokuvelisa ilaphu elinyibilikayo elingalukwanga, kodwa ixabiso lezixhobo zabo zokuvelisa lisephezulu, kwaye iinkampani eziqhelekileyo azikwazi ukucwangcisa kwaye zibeke kwimveliso ngokukhawuleza, ngokungafaniyo nokuveliswa okuzenzekelayo koomatshini bemaski. isicwangciso somgca. Ilaphu elinyibilikisiweyo kunzima ukulifumana ngenxa yobonelelo lwemathiriyeli ekrwada, imigca yokuvelisa izixhobo ezimbalwa, imveliso ephantsi, ukuqalisa kade komsebenzi, kunye nemfuno ephezulu. Ngokwemathiriyeli ekrwada, nguDaun, Shengjin, Basel kuphela, njl.njl. ababezibonelela phambi koMnyhadala waseNtwasahlobo.
 Kwiintsuku zamva nje, abaninzi abavelisi abalungisiweyo basekhaya abanjengoKingfa baye baqalisa izinto ezitshintshiweyo ezinyibilikayo, ezinokunciphisa ukunqongophala konikezelo kwinqanaba elithile. Nangona kunjalo, imigca yemveliso enyibilikayo yabakhiqizi abaninzi inokubonelela ngempahla ngokulandelelana kweetoni yonke imihla. Ubonelelo lwabaninzi abavelisi belaphu abangalukiweyo be-PP abanyibilikisiweyo bangaphantsi kweetoni ezi-3, kwaye akukho mashishini amaninzi amakhulu.
I-Zhejiang Yanpeng Nonwoven Machinery Co., Ltd., engumenzi oqeqeshiweyo osebenza kwi-reaserch kunye nophuhliso lwemigca yemveliso engalukwanga iminyaka engaphezu kwe-15, umgca wemveliso we-PP we-spunbond ungowona mveliso uphambili wenkampani yethu, kunye nomgca wemveliso. (ezinje nge S, SS, SSS... etc) ungenza ilaphu elingalukwanga eliyimpahla yeengxowa ezingalukwanga.
Ukusukela ukuba iNkampani yaseMelika i-Exxon (EXXON) ithengise itekhnoloji yokunyibilika kwi-1960s, itekhnoloji ye-melt-blown spinning iye yaphuhliswa ngokukhawuleza. I-Melt-blown nonwovens inokuyilwa ukufezekisa imisebenzi efunekayo yokucoca. Ke ngoko, ii-nonwovens ezinyibilikayo ziyakwazi Ukutshiza iimveliso zokucoca zinokubuyisela ngokucwangcisiweyo izixhobo zemveli kwiinkalo ezahlukeneyo.
Iintsinga ze-ultrafine (0.015den) ze-nonwovens ezinyibilikayo ezinyibilikayo kunye nesakhiwo se-labyrinth esine-dimensional-dimensional eyenziwe yi-fibers 'self-adhesion kunye nokuphonswa kwe-space yahluke ngokupheleleyo kwi-fiber distribution kumalaphu emveli kunye ne-nonwovens enamakhadi. I-nonwovens etshiziweyo ineempawu zendawo enkulu yendawo ethile, i-porosity ephezulu (≥80%), i-voids ecwengileyo (i-pore diameter ≤1μm), kunye nokusebenza okugqwesileyo kokucoca okuphezulu kakhulu kunezinye izixhobo zokucoca eziqhelekileyo.
Ukongeza, ayingawo onke amalaphu angalukwanga anyibilikayo afanelekileyo ukuba asetyenziswe njengomaleko wokucoca phakathi kokhuseleko lwenqanaba lezonyango. Kuphela i-electret melt-blown-non-loven e-non-woven inokufikelela kwimpumelelo ethile yokucoca.
