Tam sim no qhov teeb meem ntawm melt blown fabric kev lag luam
Kev tsim cov yaj tshuab tsis-woven hauv Suav teb yog kwv yees li 53400 tons. Vim qhov kev thov muaj zog rau cov qhov ncauj qhov ntswg hauv tsev, tshwj xeeb tshaj yog cov npog ntsej muag kho mob, muaj qhov sib txawv rau lub sijhawm luv luv rau cov ntaub qhwv tsis-woven. Txawm li cas los xij, vim tias maj mam tswj kev kis tus kabmob sab nraud Hubei Xeev, qhov kev thov rau lub qhov ncauj qhov ntswg yuav tsum maj mam txo. Cov hauv qab no yog ib qho kev soj ntsuam ntawm qhov xwm txheej tam sim no ntawm kev lag luam melt blown fabric.
Melt cua tshuab tuaj yeem hu ua "lub siab" ntawm lub qhov ncauj qhov ntswg kho mob thiab N95 qhov ncauj qhov ntswg. Daim ntawv tshaj tawm kev lag luam kev lag luam ntawm cov tshuab ziab khaub ncaws kev lag luam taw qhia tias muaj tsawg dua kev lag luam uas tuaj yeem muab cov ntaub nplaum yaj, uas yog qhov tseem ceeb dua rau lub ntsej muag kho mob. Kev lag luam kev lag luam ntawm cov lag luam uas cuam tshuam nrog cov khoom siv yaj yog feem ntau yog nyob rau hauv Jiangsu (23.53%), Zhejiang (13.73%), thiab Henan (11.76%) xeev, tag nrho cov accounting rau ntau tshaj 10%, accounting rau 49.02% ntawm lub teb chaws tag nrho. Hubei Xeev muaj 2465 lub tuam txhab tsis-woven npuag, suav txog tsuas yog 4.03% ntawm tag nrho lub tebchaws.
Txoj kev loj hlob loj ntawm cov ntaub nplaum uas tsis-woven hauv Suav teb tau pib thaum pib ntawm lub xyoo pua no thiab mus txog nws qhov siab tshaj plaws hauv xyoo 2009. Hauv kaum xyoo dhau los, vim muaj kev cuam tshuam ntawm European thiab Asmeskas cov nuj nqis ntsoog thiab kev poob qis hauv kev lag luam hauv tsev, txoj kev loj hlob ceev tau qeeb, thiab kev ua lag luam tau dhau los ua kev xav ntau dua.
Los ntawm qhov kev xav ntawm kev lag luam saw, qhov xwm txheej tam sim no ntawm kev lag luam yaj tshuab ziab khaub ncaws feem ntau yog nyob ntawm polypropylene ua cov khoom siv tseem ceeb, thiab txoj kab uas hla fiber ntau tuaj yeem ncav cuag 1-5 microns. Vim tias qhov tseeb tias polypropylene, cov khoom siv raw rau cov tshuab ziab khaub ncaws, yog los ntawm cov roj av, cov tuam txhab petrochemical muaj cov txiaj ntsig zoo hauv kev tsim cov tshuab ziab khaub ncaws. Cov khoom tshwj xeeb rau yaj tshuab yog polypropylene nrog siab yaj Performance index. Qhov siab dua qhov ntsuas qhov ntsuas ntawm polypropylene, qhov zoo dua cov fibers txau tawm, thiab qhov zoo dua qhov pom kev ua haujlwm ntawm cov ntaub yaj yaj.
