Qhov thaiv cov nyhuv ntawm yaj yaj tshuab rab koob punched nonwovens ntawm tus kab mob thiab PM2.5 yog qhov tsis suav nrog lwm qhov tsis xws
Lub koob koob punched cov-daim npog tiv thaiv npog yog rau cov khoom siv tiv thaiv ua pa. Cov khoom tseem ceeb ntawm kev tiv thaiv yog cov teeb meem me me, suav nrog cov plua plav, huab, pa taws thiab kab mob. Cov xeb tuaj yeem nkag mus rau hauv tib neeg lub ntsws yog qhov tsawg heev thiab muaj kev phom sij rau kev noj qab haus huv. Txhua yam pneumoconiosis" rau txim" kuj tseem yog cov khoom tiv thaiv lub ntsiab ntawm cov npog ntsej muag tiv thaiv.
Qhov zoo ntawm cov khoom lim pom txiav txim siab pom kev ua haujlwm zoo. Cov khoom siv tseem ceeb ntawm cov qhov ncauj tiv thaiv feem ntau yog rab koob punched tsis-ntaub npuag, tuaj yeem paub cov lim ua tiv thaiv kev ua haujlwm los ntawm kev lim ntaub fiber ntau. Tam sim no, feem ntau hom kev tiv thaiv kev lag luam tau txais cov qauv ntawm" lub suab tsis siv lub tshuab hluav taws xob + electrostatic adsorption" kom cuam tshuam cov PM2.5 hais thiab hmoov av. Qhov thaiv cov nyhuv ntawm meltblown nonwovens ntawm tus kab mob thiab PM2.5 yog dhau kev muaj peev xwm kev sib tw ntawm lwm qhov tsis yog. Nrog cov qauv tsim peb-txheej, nws tsim cov chaw ntim nrog lub ntsej muag, yuam cov pa paug mus rau nqus tau thiab lim tawm los ntawm tib neeg lub cev rau kev ua pa, thiab tus lim pom ntawm cov teeb meem feem ntau khaws cia saum 95%. Lub tshuab hluav taws xob zoo li qub, electret meltblown nonwovens tuaj yeem ntes ntau yam nrog cov nqi sib txawv los ntawm electrostatic adsorption mechanism, yog li txhawm rau txhim kho qhov pom kev ua haujlwm ntawm meltblown nonwovens thiab ntxiv dag zog rau kev tiv thaiv ntawm lub ntsej muag. Lub hauv paus ntsiab lus ntawm fiber ntau lim plua plav feem ntau suav nrog electrostatic adsorption, lub ntiajteb txawj nqus tso, inertial deposition, diffusion deposition thiab kev ntes ncaj qha.
Raws li cov kws tshaj lij, tus nqi ntawm kev ua haujlwm meltblown nonwovens zoo yog nyob nruab nrab ntawm 30000 yuan thiab 60000 yuan ib tuj, thiab 300000 qhov ncauj qhov ntswg tuaj yeem tsim ib tuj ntawm meltblown nonwovens. Qhov kev tiv thaiv zoo ntawm cov hom tshuaj tsuag tsis-woven cov ntaub ntawv tuaj yeem ncav qib B. Txawm li cas los xij, tam sim no, cov tuam ntxhab hauv khw yuav meltblown nonwoven cov ntaub qhwv 10000 yuan mus rau 20000 yuan los tsim thiab muag cov ntsej muag tiv thaiv qis, cuam tshuam kev lag luam kev txiav txim.
Qhov kev tiv thaiv ntawm lub npog ntsej muag tsis yog tsuas yog cuam tshuam rau kev lim dej ntawm cov npog ntsej muag, tab sis kuj hais txog qhov sib khi (cov dej xau) ntawm tib neeg lub ntsej muag. Kev sib khi thiab ntsej muag tiv thaiv cov cuab yeej tiv thaiv cov pa ua pa ncaj qha cuam tshuam. Qhov kev qhia tshwj xeeb ntawm lub npog ntsej muag yuav tsum tau xaiv, thiab lub ntsej muag npog' s lub ntsej muag haum yuav tsum raug txiav txim siab. Cov ntaub npog tiv thaiv zoo, huab cua sab nraud lub npog ntsej muag tsis yooj yim nkag rau hauv lub npog ntsej muag los ntawm ntug thiab nqus tau los ntawm tib neeg lub cev, vim tias lub ntsej muag tsis kaw, lub npog ntsej muag tsis hnav. Daim ntawv tshuaj ntsuam ntawm cov neeg siv khoom pom tias cov txiaj ntsig ntawm kev sib khi dav dav tau zoo dua li ntawm pob ntseg ntsej muag, thiab lub khob hom zoo dua li qhov ntim cov ntsaws ruaj ruaj. Raws li cov tuam txhab kev noj qab haus huv, ntxiv qee qhov roj av ntawm lub ntsej muag lub ntsej muag thiab txuas lub qhov ntswg nrog aluminium qhov ntswg tawm tuaj yeem xyuas qhov teeb meem ntawm daim npog ntsej muag.
