Melt blown non-woven fabric yog qhov tseem ceeb ntawm cov txheej txheem lim dej ntawm lub qhov ncauj qhov ntswg!
Melt tshuab nonwoven ntaub
Melt cua tshuab yog tsim los ntawm polypropylene ua cov khoom tseem ceeb, thiab cov kab fiber ntau tuaj yeem ncav cuag 1-5 microns. Cov fibers ultrafine nrog cov qauv capillary tshwj xeeb muaj ntau qhov sib txawv, cov qauv fluffy, thiab zoo wrinkle tsis kam, uas ua rau muaj pes tsawg leeg thiab thaj chaw ntawm fibers hauv ib cheeb tsam, yog li ua rau cov ntaub meltblown muaj kev lim dej zoo, tiv thaiv, rwb thaiv tsev, thiab roj nqus cov khoom. Nws tuaj yeem siv rau hauv thaj chaw xws li cov ntaub ntawv huab cua thiab kua lim dej, cov ntaub ntawv cais tawm, cov ntaub ntawv nqus, cov ntaub ntawv npog, cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv roj absorbing, thiab cov ntaub so ntswg.
Cov txheej txheem ntawm yaj tshuab tsis-woven npuag: polymer pub - yaj extrusion - fiber ntau tsim - fiber ntau txias - web tsim - txhawb rau hauv ntaub.

Meltblown ntaub tuaj yeem hu ua "lub siab" ntawm lub ntsej muag kho mob phais thiab N95 qhov ncauj qhov ntswg
Kev kho mob qhov ncauj qhov ntswg thiab N95 qhov ncauj qhov ntswg feem ntau txais yuav ntau txheej txheej, luv luv raws li SMS qauv: sab hauv thiab sab nrauv yog ib txheej txheej spunbond (S); Cov txheej txheem nruab nrab yog cov yaj yaj txheej (M), uas feem ntau muab faib ua ib txheej lossis ntau txheej.
Lub qhov ncauj qhov ntswg yog feem ntau ua los ntawm PP spunbond + yaj tshuab + PP spunbond, los yog luv fibers tuaj yeem siv rau hauv ib txheej los txhim kho daim tawv nqaij. Lub npog ntsej muag peb-dimensional lub khob zoo li feem ntau yog ua los ntawm PET polyester koob punched paj rwb + meltblown + koob punched paj rwb lossis PP spunbond. Ntawm lawv, txheej txheej yog ua los ntawm cov ntaub tsis-woven nrog kev kho dej tsis zoo, feem ntau yog siv los cais cov tee dej los ntawm cov neeg mob; Qhov nruab nrab meltblown txheej yog ib qho tshwj xeeb kho cov ntaub nplaum uas tsis yog-woven nrog cov lim dej zoo heev, tiv thaiv, rwb thaiv tsev, thiab cov khoom nqus roj, uas yog ib qho tseem ceeb raw khoom rau kev tsim cov qhov ncauj qhov ntswg; Cov txheej sab hauv yog ua los ntawm cov ntaub uas tsis yog-woven.
Txawm hais tias spunbond txheej (S) thiab meltblown txheej (M) ntawm lub npog ntsej muag yog ob qho tib si tsis-woven fabrics thiab ua los ntawm polypropylene, lawv cov txheej txheem tsim tsis zoo ib yam.
Ntawm lawv, txoj kab uas hla ntawm spunbond txheej fibers ntawm ob sab yog tuab, nyob ib ncig ntawm 20 microns; Lub fiber txoj kab uas hla ntawm lub yaj cua tshuab hauv nruab nrab tsuas yog 2 microns, ua los ntawm cov khoom siv polypropylene hu ua high melt fat fiber.
Txoj kev loj hlob ntawm yaj tshuab tsis woven fabrics nyob rau hauv Suav teb
Tuam Tshoj yog lub ntiaj teb loj tshaj plaws cov neeg tsim khoom ntawm non-woven fabrics, nrog ib tug ntau lawm ntim ntawm kwv yees li 5.94 lab tons nyob rau hauv 2018, tab sis zus tau tej cov yaj tshuab tsis-woven fabrics yog tsawg heev.
Raws li kev txheeb cais ntawm Tuam Tshoj Industrial Textile Industry Association, cov txheej txheem tsim khoom ntawm Tuam Tshoj txoj kev lag luam non-woven npuag yog spunbond. Nyob rau hauv 2018, zus tau tej cov spunbond nonwoven npuag yog 2.9712 lab tons, accounting rau 50% ntawm tag nrho cov nonwoven fabric ntau lawm, mas siv nyob rau hauv lub teb ntawm cov ntaub ntawv huv, thiab lwm yam; Qhov kev faib ua feem ntawm yaj tshuab tshuab yog tsuas yog 0.9%.
Raws li qhov kev suav no, kev tsim khoom hauv tsev ntawm cov khoom siv hluav taws xob tsis zoo hauv xyoo 2018 yog 53500 tons hauv ib xyoos. Cov ntaub meltblown no tsis yog siv rau lub qhov ncauj qhov ntswg xwb, tab sis kuj yog cov ntaub ntawv tiv thaiv ib puag ncig, cov ntaub ntawv khaub ncaws, cov khoom siv roj teeb cais, cov ntaub ntawv so, thiab lwm yam.
Raws li kev sib kis, qhov kev thov rau lub qhov ncauj qhov ntswg tau nce ntau. Raws li cov ntaub ntawv kev suav pej xeem thib plaub hauv tebchaws, tag nrho cov neeg ua haujlwm ntawm cov neeg ua haujlwm raug cai thiab cov lag luam ib leeg yog siab txog 533 lab tus tib neeg. Muab xam raws li ib daim npog ntsej muag rau ib tus neeg hauv ib hnub, tsawg kawg yog 533 lab lub npog ntsej muag yuav tsum tau siv rau ib hnub.
Raws li cov ntaub ntawv los ntawm Ministry of Industry thiab Information Technology, qhov siab tshaj plaws niaj hnub tsim muaj peev xwm ntawm lub ntsej muag hauv Suav teb tam sim no yog 20 lab.
Muaj qhov tsis txaus ntawm lub qhov ncauj qhov ntswg, thiab ntau lub tuam txhab tau pib tsim lub qhov ncauj qhov ntswg hla ciam teb. Raws li Tianyancha cov ntaub ntawv, raws li kev hloov pauv hauv cov ntaub ntawv sau npe ua lag luam, txij Lub Ib Hlis 1 txog Lub Ob Hlis 7, 2020, ntau dua 3000 lub tuam txhab thoob plaws lub tebchaws tau ntxiv cov lag luam xws li "qhov ncauj qhov ntswg, khaub ncaws tiv thaiv, tshuaj tua kab mob, ntsuas kub, thiab khoom siv kho mob" rau lawv txoj kev lag luam.
Piv nrog rau lub npog ntsej muag manufacturers, tsis muaj ntau lub tshuab ziab khaub ncaws uas tsis yog woven npuag ntau lawm. Hauv qhov xwm txheej no, tsoomfwv tau npaj qee qhov chaw lag luam los pib tsim khoom thiab ua kom muaj peev xwm ntau lawm. Txawm li cas los xij, tam sim no, ntsib qhov kev thov rau meltblown non-woven fabrics ntawm textile platforms thiab ntawm textile enthusiasts, nws tsis yog optimistic. Tuam Tshoj txoj kev tsim khoom ceev tau ntsib cov kev sib tw uas tsis tau muaj dua los ntawm kev kis tus kabmob no! Tab sis kuv ntseeg hais tias nyob rau hauv lub ntsej muag ntawm ib tug maj mam txhim kho qhov teeb meem, txhua yam yuav tau zoo dua.
