yaj tshuab tshuab rau lub ntsej muag daim npog qhov ncauj
Nrog rau kev sib kis tas mus li ntawm qhov xwm txheej thoob ntiaj teb, qhov kev thov rau cov ntaub ntawv tiv thaiv kab mob sib kis hauv cov tebchaws thoob ntiaj teb tau nce ntxiv.Peb lub tuam txhab koom tes nrog cov tuam txhab loj hauv tebchaws kom ua tau raws li qhov xav tau ntawm kev tiv thaiv kab mob sib kis hauv tebchaws, thiab tib lub sijhawm, peb tab tom ua txhua yam los muab cov ntaub ntawv xav tau sai sai rau kev tawm tsam thoob ntiaj teb tiv thaiv covid-19.Covid-19 qhov xwm txheej hauv Suav teb muaj. tau tswj tau yooj yim, thiab cov nqi ntawm cov ntaub tsis-woven thiab cov ntaub meltblown tau poob qis, uas tuaj yeem txuag tau ntau tus nqi rau cov neeg siv khoom txawv teb chaws.Nyob rau tib lub sijhawm, peb tuaj yeem ua kom muaj kev txhim kho ntawm cov khoom zoo, kom cov neeg siv khoom tuaj yeem yuav cov khoom zoo ntawm tus nqi zoo tshaj plaws, thiab paub cov neeg siv khoom 'kev txiav txim rov qab tsis tu ncua.Peb muab cov khoom zoo thiab tus nqi, txais tos rau cov neeg siv khoom thoob ntiaj teb los sab laj.
Melt-blown nonwoven siv polypropylene ua raw khoom.Lub fiber inch tuaj yeem ncav cuag 1to5um.Muaj ntau voids, fluffy qauv thiab zoo fold kuj.Lub Melt-blown nonwoven muaj cov qauv capillary tshwj xeeb uas ua rau muaj pes tsawg leeg thiab thaj chaw ntawm fibers hauv ib cheeb tsam, kom cov yaj-tshuab nonwoven muaj cov lim dej zoo, tiv thaiv, rwb thaiv tsev kub thiab roj nqus.
Melt-blown nonwoven yog cov khoom tseem ceeb ntawm lub npog ntsej muag.Melt blown npuag muaj lub zog pom kev ua tau zoo, zoo heev hauv kev pom, becteria tsis kam, adsorption, thiab lwm yam.
PRODUCTION METOD
Cov cua kub ceev nrawm nrawm rub cov kwj ntawm cov polymer yaj extruded los ntawm cov tuag orifice ntawm cov tuag uas tsim cov fibers ultra-zoo.Tom qab ntawd, peb sau lawv ntawm condensed screen lossis cov menyuam thiab tib lub sijhawm sib txuas lawv tus kheej los ua Melt-blown nonwoven fabric.
Meltblown txheej txheem
Polypropylene PP particles → melt extrusion → metering twj → melt-blown tuag lub taub hau los ua ke → yaj zoo txaus stretching → txias → txais khoom → electrostatic electret → trimming winding tshuab
Cov khoom siv Meltblown
Cov khoom tseem ceeb: pub tshuab, ntsia hlau extruder, metering twj tso kua mis, yaj-blown tuag lub taub hau los ua ke, cua compressor, cua rhaub, txais ntaus ntawv, electrostatic electret, winding ntaus ntawv.
Cov kab ntau lawm yog nruab nrog cov cuab yeej zoo tshaj plaws abrasive, Sanxin electrostatic electret, zoo yaj cov ntaub ntawv ntawm Jinfa technology, thiab cov kws tshaj lij thiab cov khoom siv tshuaj ntsuam xyuas los xyuas kom meej tias cov khoom zoo tshaj plaws yaj tshuab.kov yeej qhov poob ntawm static electret thiab xyuas kom lub sij hawm ntev electret ntawm meltblown daim ntaub.
Ntau tus yam ntxwv ntawm daim ntaub meltblown: raws li cov qauv ntawm GB / T32610-2016, GB / 19083-2010, YY / T0969-2013 (daim npog kho mob pov tseg), YY / T0469-2011 (kev kho mob daim npog qhov ncauj), thiab lwm yam. kuj tuaj yeem tsim tau raws li qhov xav tau ntawm cov neeg siv khoom.
AlI cov khoom yog nyob rau hauv tus txheej txheem ntau lawm, Zoo ntseeg tau.
Lim efficiency yog ib qho tseem ceeb ntawm kev ua yeeb yam ntawm lub qhov ncauj qhov ntswg.Cov qhov ncauj qhov ntswg sib txawv muaj cov haujlwm ntawm kev lim cov plua plav, cov pa phem thiab cov kab mob.Yog li ntawd, theem ntawm kev ua kom pom tseeb ncaj qha cuam tshuam qhov zoo ntawm lub npog ntsej muag.
Cov ntaub nplaum uas siv los ua lub npog ntsej muag yuav tsum tau kuaj xyuas nruj raws li cov qauv.Cov nyhuv lim dej yog ib qho tseem ceeb tshaj plaws ntawm cov khoom kuaj.Aerosol hais txog qee qhov concentration thiab particle loj tis yog tsim los ntawm lub tshuab hluav taws xob aerosol, hla lub npog ntsej muag ntawm tus nqi roj ntws, thiab cov particle concentration ua ntej thiab tom qab dhau los ntawm lub npog ntsej muag raug kuaj pom siv cov khoom siv kom pom cov khoom tsim nyog.Kev pom kev ua haujlwm ntawm lub ntsej muag lub ntsej muag rau cov khoom me me tau raug soj ntsuam raws li qhov feem pua ntawm qhov txo qis hauv cov ntsiab lus ntawm cov ntsiab lus tom qab aerosol dhau los ntawm lub npog ntsej muag.Qhov ua tau zoo ntawm cov ntaub yaj-tshuab ua los ntawm peb lub tuam txhab yog 99.1%.
