Waa maxay dunta dhalaalaysa ee dunidu raadinayso?

Maro aan tol lahayn oo dhalaalaysa ayaa asal ahaan ah lakabka shaandhaynta ee maaskarada!

dhalaali afuufo marada aan tolka lahayn

Dharka la afuufay ayaa inta badan laga sameeyaa polypropylene oo ah alaabta ceeriin ee ugu weyn, dhexroorka fiberku wuxuu gaari karaa 1-5 microns. Fiilooyinka ultrafine ee leh qaab dhismeed gaar ah ayaa leh nusqaamo badan, qaab-dhismeed qalafsan, iyo iska caabin wanaagsan oo laalaab ah, taas oo kordhisa tirada iyo dusha sare ee fiilooyinka halkii unug, sidaas awgeed dharka dhalaalka ah ayaa leh shaandhayn wanaagsan, gaashaan, dahaar, iyo sifooyinka nuugista saliidda. Waxaa loo isticmaali karaa meelaha sida hawada iyo alaabta sifaynta dareeraha ah, alaabta go'doominta, alaabta nuugista, alaabta maaskarada, alaabta dahaarka, alaabta nuugta saliidda, iyo tirtiridda maryaha.

Habka dhalaalida ee dharka aan toliyaha lahayn: quudinta polymer - dhalaalid extrusion - samaynta fiber - qaboojinta fiber - samaynta shabakada - xoojinta dharka.

Dharka dhalaalay waxaa loogu yeeri karaa "wadnaha" waji-xidhka caafimaadka iyo maaskaro N95

Maaskarada qalliinka caafimaadka iyo waji-xidhka N95 guud ahaan waxay qaataan qaab dhismeed dhowr lakab ah, oo loo soo gaabiyo qaab dhismeedka SMS: dhinacyada gudaha iyo dibedda waa lakabyo hal lakab ah oo spunbond ah (S); Lakabka dhexe waa lakabka dhalaalka ah (M), kaas oo guud ahaan loo qaybiyo hal lakab ama lakabyo badan.

Maaskarada fidsan ayaa guud ahaan laga sameeyaa PP spunbond+dhalaalaya+ PP spunbond, ama fiilooyin gaaban ayaa loo isticmaali karaa hal lakab si loo hagaajiyo qaabka maqaarka. Maaskaro saddex-geesood ah oo koob u samaysan ayaa inta badan laga sameeyaa cirbadda PET polyester-ka oo la feeray suuf + dhalaalay+ irbad la feeray suuf ama spunbond PP. Waxaa ka mid ah, lakabka sare wuxuu ka samaysan yahay dhar aan tol lahayn oo leh daaweyn aan biyuhu lahayn, oo inta badan loo isticmaalo in lagu go'doomiyo dhibcaha ay buufiyaan bukaanada; Lakabka dhalaalka dhexe waa maro si gaar ah loo daweeyay oo dhalaalaysa oo aan tolnayn oo leh shaandhayn heer sare ah, gaashaan, dahaar, iyo sifooyin nuugista saliidda, taas oo ah walxo muhiim ah oo cayriin ah oo soo saara maaskaro; Lakabka gudaha wuxuu ka samaysan yahay maro caadi ah oo aan tol lahayn.

Inkasta oo lakabka spunbond (S) iyo lakabka dhalaalidda (M) ee maaskarada ay labaduba yihiin dhar aan tolmo lahayn oo laga sameeyay polypropylene, habraacyadooda wax-soo-saarkoodu isku mid maaha.

Waxaa ka mid ah, dhexroorka fiilooyinka lakabka spunbond ee labada dhinac waa dhumuc yar, qiyaastii 20 microns; Dhexroorka fiber-ka lakabka dhalaalka ah ee dhexda ku jira waa 2 microns, oo ka samaysan walxo polypropylene ah oo loo yaqaan fiber dufan dhalaalaysa oo sarreeya.

Heerka horumarinta ee dhalaalidda afuufi dhar aan tolnayn ee Shiinaha

Shiinaha waa wax soo saarka ugu weyn adduunka ee dharka aan toliyaha ahayn, oo leh mugga wax soo saarka qiyaastii 5.94 milyan oo tan sanadka 2018, laakiin wax soo saarka dhalaalidda dharka aan toliyaha ahayn ayaa aad u hooseeya.

Marka loo eego tirakoobka Ururka Warshadaha Warshadaha ee Shiinaha, habka wax soo saarka ee warshadaha dharka aan tolmada lahayn ee Shiinaha ayaa inta badan ah spunbond. In 2018, wax soo saarka ee dhar nonwoven spunbond ahaa 2.9712 million tons, xisaabaadka 50% ee wadarta guud ee wax soo saarka dharka nonwoven, inta badan loo isticmaalo beeraha alaabta nadaafadda, iwm; Qaybta tignoolajiyada dhalaalaysa waa kaliya 0.9%.

Iyada oo ku saleysan xisaabintan, wax soo saarka gudaha ee dhalaalidda maro aan-xidhka lahayn ee 2018 wuxuu ahaa 53500 tan sannadkii. Dharkan dhalaalaysa looma isticmaalo maaskaro oo keliya, laakiin sidoo kale waxa loo isticmaalaa agabka ilaalinta deegaanka, agabka dharka, agabka kala saara baytariyada, alaabta wax lagu masaxo, iwm.

Inta lagu jiro faafitaanka, baahida loo qabo waji-xidhka ayaa si weyn u kordhay. Marka loo eego xogta tirakoobka dhaqaalaha qaranka ee afraad, wadarta guud ee dadka shaqaalaysiinta ee hay'adaha sharciga ah ee gudaha iyo ganacsiyada gaarka ah ayaa gaaraya ilaa 533 milyan oo qof. Marka loo eego hal maaskaro qofkiiba maalintii, ugu yaraan 533 milyan oo maaskaro ayaa loo baahan yahay maalintii.

Sida laga soo xigtay xogta Wasaaradda Warshadaha iyo Tignoolajiyada Macluumaadka, awoodda wax soo saarka maalinlaha ah ee maaskaro ee Shiinaha ayaa hadda ah 20 milyan.

Waxaa jirta gabaabsi aad u weyn oo ah maaskaro, shirkado badana waxay bilaabeen inay soo saaraan waji-xidho xuduudaha. Marka loo eego xogta Tianyancha, oo ku saleysan isbeddelada macluumaadka diiwaangelinta ganacsiga, laga bilaabo Janaayo 1 ilaa Febraayo 7, 2020, in kabadan 3000 shirkadood oo dalka oo dhan ah ayaa ku daray ganacsiyo ay ka mid yihiin "maaskaro, dharka ilaalinta, jeermiska jeermiska, heerkulbeegyada, iyo aaladaha caafimaadka" baaxadooda ganacsi.

Marka la barbar dhigo kuwa wax soo saara maaskaro, ma jiraan shirkado wax soo saar oo aan tol lahayn oo dhalaaliyay. Xaaladdan oo kale, dawladdu waxay abaabushay qaar ka mid ah shirkadaha ganacsiga si ay si buuxda u bilaabaan wax-soo-saarka, korna u qaadaan awoodda wax-soo-saarka. Si kastaba ha ahaatee, hadda, oo wajahaya baahida loo qabo dhar dhalaalaysa oo aan tol lahayn oo ku yaal dhufashada dharka iyo kuwa xiiseeya dharka, maaha rajo. Xawaaraha wax soo saarka Shiinaha ayaa wajahaya caqabado aan horay loo arag oo cudurkan ah! Laakiin waxaan aaminsanahay in marka la eego xaalad si tartiib tartiib ah u soo hagaagaysa, wax walba way fiicnaan doonaan.
