yaj blown ntaub rau lub ntsej muag lub ntsej muag
Nrog rau qhov teeb meem kev sib kis thoob ntiaj teb uas txuas ntxiv mus, qhov kev thov rau cov ntaub ntawv tiv thaiv kev sib kis hauv cov teb chaws thoob ntiaj teb tab tom nce ntxiv. Peb lub tuam txhab koom tes nrog cov tuam txhab loj hauv tsev kom tau raws li qhov xav tau ntawm kev tiv thaiv kev sib kis hauv tsev, thiab tib lub sijhawm, peb tab tom ua txhua yam kev rau siab los muab cov ntaub ntawv xav tau sai rau kev sib ntaus sib tua thoob ntiaj teb tiv thaiv covid-19. Qhov xwm txheej covid-19 hauv Suav teb tau raug tswj hwm, thiab tus nqi ntawm cov ntaub tsis-woven thiab cov ntaub meltblown poob qis, uas tuaj yeem txuag tau ntau tus nqi rau cov neeg siv khoom txawv teb chaws. Tib lub sijhawm, peb tuaj yeem ua kom zoo dua ntawm cov khoom zoo, yog li cov neeg siv khoom tuaj yeem yuav cov khoom zoo dua ntawm tus nqi zoo tshaj plaws, thiab ua tiav cov neeg siv khoom cov xaj rov qab tas li. Peb muab cov khoom zoo thiab tus nqi zoo, txais tos cov neeg yuav khoom thoob ntiaj teb los sab laj.
Cov ntaub tsis-woven uas yaj tau siv polypropylene ua cov khoom siv tseem ceeb. Lub taub ntawm cov fiber tuaj yeem ncav cuag 1 txog 5 um. Muaj ntau qhov khoob, cov qauv fluffy thiab zoo tiv taus qhov quav. Cov ntaub tsis-woven uas yaj tau muaj cov qauv capillary tshwj xeeb uas ua rau cov fiber ntau ntxiv thiab thaj chaw ntawm cov fiber ib cheeb tsam, yog li cov ntaub tsis-woven uas yaj tau muaj kev lim dej zoo, tiv thaiv, rwb thaiv cua sov thiab nqus roj.
Cov ntaub tsis yog ntaub uas yaj tawm yog cov khoom siv tseem ceeb ntawm lub ntsej muag. Cov ntaub yaj tawm muaj kev ua haujlwm lim dej zoo, muaj txiaj ntsig zoo hauv kev lim dej, tiv taus kab mob, nqus tau dej, thiab lwm yam.
TXOJ KEV UA HAUJ LWM
Ib qho cua kub ceev ceev rub ib txoj kab nyias nyias ntawm cov polymer yaj uas raug rho tawm ntawm lub qhov tuag ntawm lub pwm uas tsim cov fibers zoo heev. Tom qab ntawd, peb sau lawv rau ntawm lub vijtsam condensed lossis roller thiab tib lub sijhawm txuas lawv tus kheej kom ua cov ntaub Melt-blown nonwoven.
Cov txheej txheem yaj
Cov khoom me me PP polypropylene → yaj extrusion → twj ntsuas → yaj-blown tuag lub taub hau sib dhos → yaj ntws zoo ncab → txias → txais khoom siv → electrostatic electret → trimming winding tshuab
Cov khoom siv yaj
Cov khoom siv tseem ceeb: tshuab pub mis, ntsia hlau extruder, twj ntsuas, lub taub hau tuag yaj, cua compressor, cua sov, txais khoom siv, electrostatic electret, winding device.
Cov kab ntau lawm muaj cov cuab yeej abrasive zoo tshaj plaws, Sanxin electrostatic electret, cov khoom siv yaj zoo ntawm Jinfa thev naus laus zis, thiab cov kws tshaj lij hauv chaw kuaj mob thiab cov khoom siv tshuaj xyuas txawv teb chaws kom ntseeg tau tias cov ntaub yaj zoo. Kov yeej qhov poob qis ntawm static electret thiab xyuas kom meej tias cov ntaub yaj siv tau ntev.
Ntau yam ntxwv ntawm daim ntaub meltblown: raws li cov qauv ntawm GB / T32610-2016, GB / 19083-2010, YY / T0969-2013 (lub npog ntsej muag kho mob pov tseg), YY / T0469-2011 (lub npog ntsej muag phais kho mob), thiab lwm yam, nws kuj tuaj yeem tsim tau raws li qhov xav tau ntawm cov neeg siv khoom.
Cov khoom AlI yog nyob rau hauv cov txheej txheem tsim khoom txheem, Zoo ntseeg tau.
Kev lim dej zoo yog ib qho ntawm cov kev ua tau zoo tseem ceeb ntawm cov ntaub npog qhov ncauj. Cov ntaub npog qhov ncauj sib txawv muaj cov haujlwm lim cov hmoov av, cov pa phem thiab cov kab mob. Yog li ntawd, qib kev lim dej zoo qhia ncaj qha rau qhov zoo ntawm lub ntaub npog qhov ncauj.
Daim ntaub uas yaj tawm los siv ua lub npog ntsej muag yuav tsum tau kuaj xyuas raws li cov qauv. Qhov cuam tshuam ntawm kev lim dej yog ib qho ntawm cov khoom sim tseem ceeb tshaj plaws. Cov khoom me me aerosol ntawm qee qhov concentration thiab qhov loj me ntawm cov khoom me me raug tsim los ntawm lub tshuab hluav taws xob aerosol, hla lub npog ntsej muag ntawm qhov ntsuas roj ntws, thiab qhov concentration ntawm cov khoom me me ua ntej thiab tom qab dhau lub npog ntsej muag raug kuaj pom siv lub cuab yeej kuaj pom cov khoom me me. Qhov ua tau zoo ntawm kev lim dej ntawm lub cev lub ntsej muag rau cov khoom me me tau raug soj ntsuam raws li feem pua ntawm kev txo qis ntawm qhov concentration ntawm cov khoom me me tom qab aerosol dhau los ntawm lub cev lub ntsej muag. Qhov ua tau zoo ntawm daim ntaub yaj tawm los ntawm peb lub tuam txhab yog 99.1%.
