Ilaphu elingalukwanga elivuthelweyo ngoyena ngundoqo wokucoca imaski!
Nyibilikisa ilaphu elingaphothiweyo
Ilaphu elivuthelweyo linyibilika lenziwe ikakhulu ngepolypropylene njengeyona nto iphambili ekrwada, kwaye idiameter yefiber inokufikelela kwi-1-5 microns. Imicu ye-ultrafine ene-capillary structure inezikhewu ezininzi, i-fluffy structure, kunye nokumelana nokushwabana okulungileyo, okwandisa inani kunye nommandla we-fiber kwindawo nganye yeyunithi, ngaloo ndlela yenza ilaphu elinyibilikayo libe nokucoca okulungileyo, ukukhusela, ukugquma, kunye neempawu zokufunxa ioli. Ingasetyenziswa kumasimi anje ngezixhobo zokucoca umoya kunye nolwelo, izixhobo zokuzihlukanisa, izinto zokufunxa, imathiriyeli yemaski, izinto zokugquma, izinto ezifunxa ioyile, kunye namalaphu osula.
Inkqubo yokunyibilika kwelaphu elingalukiweyo elivuthelweyo: ukondla kwepolymer - ukunyibilika kwe-extrusion - ukwakheka kwefayibha - ukupholisa ifayibha - ukwakhiwa kwewebhu - ukomelezwa kwilaphu.

Ilaphu le-Meltblown linokubizwa ngokuba "yintliziyo" yeemaski zoqhaqho lwezonyango kunye ne-N95 masks
Iimaski zotyando lwezonyango kunye neemaski ze-N95 ngokubanzi zamkela ulwakhiwo olunemigangatho emininzi, lufinyeziwe njengesakhiwo seSMS: amacala angaphakathi nangaphandle anomaleko we-spunbond (S); Umaleko ophakathi ngumaleko ovuthelweyo onyibilikayo (M), owahlulwe ngokubanzi ube ngumaleko omnye okanye iileya ezininzi.
Iimaski ezicaba zenziwe ngokubanzi ngePP spunbond + melt blown + PP spunbond, okanye iintsinga ezimfutshane zingasetyenziswa kumaleko omnye ukuphucula ukuthungwa kwesikhumba. Imaski emile okwekomityi enemacala amathathu ihlala yenziwe ngePET polyester inaliti ehlatywe umqhaphu+onyibilikayo+inaliti ehlatyiweyo yomqhaphu okanye iPP spunbond. Phakathi kwazo, umaleko wangaphandle wenziwa ngelaphu elingalukwanga kunye nonyango olungenamanzi, olusetyenziswa ikakhulu ukwahlula amathontsi atshizwe zizigulane; Umaleko onyibilikisiweyo ophakathi lilaphu elingalukwanga elinyibilikayo eliphathwe ngokukodwa elinokucoca, ukukhusela, ukugquma, kunye neempawu zokufunxa ioyile, nto leyo ibalulekileyo ekuveliseni imaski; Uluhlu lwangaphakathi lwenziwe ngelaphu eliqhelekileyo elingalukwanga.
Nangona umaleko we-spunbond (S) kunye ne-meltblown layer (M) yemaski omabini angamalaphu angalukwanga kwaye enziwe ngepolypropylene, iinkqubo zawo zokuvelisa azifani.
Phakathi kwazo, ububanzi be-spunbond layer fibers kumacala omabini bubunzima, malunga ne-20 microns; Idayamitha yefiber yomaleko onyibilikayo ovuthelweyo embindini ziimicrons ezi-2 kuphela, ezenziwe ngemathiriyeli yepolypropylene ebizwa ngokuba yi-high melt fat fiber.
Ubume bophuhliso lwamalaphu angalukwanga anyibilikayo eTshayina
I-China ngoyena mvelisi mkhulu wehlabathi wamalaphu angalukwanga, anomthamo wemveliso omalunga ne-5.94 yezigidi zeetoni ngo-2018, kodwa ukuveliswa kwamalaphu angalukwanga anyibilikayo aphantsi kakhulu.
Ngokwezibalo ze-China Industrial Textile Industry Association, inkqubo yemveliso yoshishino lwamalaphu angalukwanga eTshayina ikakhulu yi-spunbond. Ngo-2018, ukuveliswa kwelaphu le-spunbond nonwoven laliyi-2.9712 yezigidi zeetoni, kubalwa i-50% yemveliso yelaphu elingalukwanga lilonke, elisetyenziswa ikakhulu kumasimi ezinto zococeko, njl. Umyinge wobuchwephesha obunyibilikisiweyo yi-0.9% kuphela.
Ngokusekwe kolu balo, imveliso yasekhaya yamalaphu angaphothiweyo anyibilikayo ngo-2018 yayiziitoni ezingama-53500 ngonyaka. Ezi zindwangu ezinyibilikayo azisetyenziselwanga kuphela iimaski, kodwa nakwizinto zokukhusela indalo, iimpahla zempahla, izinto zokwahlula ibhetri, izinto zokucima, njl.
Ngaphantsi kobhubhane, imfuno yeemaski inyuke kakhulu. Ngokwedatha yesine yobalo-bantu loqoqosho lwesizwe, inani labantu abaqeshwayo lilonke lamaqumrhu asemthethweni asekhaya kunye namashishini ngamanye afikelela kwi-533 yezigidi zabantu. Kubalwa ngokusekwe kwimaski enye kumntu ngamnye ngosuku, ubuncinci iimaski ezizigidi ezingama-533 ziyafuneka ngosuku.
Ngokwedatha evela kwiSebe lezoShishino kunye neTekhnoloji yoLwazi, ubuninzi bemihla ngemihla bemveliso yeemaski eTshayina ngoku zizigidi ezingama-20.
Kukho ukunqongophala okukhulu kweemaski, kwaye iinkampani ezininzi ziqalisile ukuvelisa imaski ukuwela imida. Ngokutsho kwedatha ye-Tianyancha, ngokusekwe kutshintsho kulwazi lobhaliso lweshishini, ukusuka nge-1 kaJanuwari ukuya nge-7 kaFebruwari, 2020, amashishini angaphezu kwama-3000 kwilizwe liphela ongeze amashishini afana "neemaski, iimpahla ezikhuselayo, izibulala-ntsholongwane, iithemomitha, kunye nezixhobo zonyango" kushishino lwabo.
Xa kuthelekiswa nabavelisi bemaski, akukho maninzi amashishini okuvelisa ilaphu elinyibilikayo elivuthelweyo. Kule meko, urhulumente uhlanganise amashishini athile omthombo ukuba aqalise ngokupheleleyo imveliso kunye nokwandisa umthamo wemveliso. Nangona kunjalo, okwangoku, ukujongana nemfuno yamalaphu angalukwanga anyibilikisiweyo kumaqonga amalaphu naphakathi kwabathandi belaphu, alinathemba. Isantya semveliso yaseTshayina sijongene nemingeni engazange ibonwe kulo bhubhani! Kodwa ndiyakholelwa ukuba ebusweni bemeko ephuculweyo ngokuthe ngcembe, yonke into iya kuba ngcono.
