Meltblown daim ntaub

Meltblown daim ntaubyog cov khoom siv tseem ceeb ntawm cov npog ntsej muag.Meltblown daim ntaubmas siv cov polypropylene ua cov khoom tseem ceeb, thiab cov khoom siv fiber ntau tuaj yeem ncav cuag li 1 txog 5 microns. Qhov ncauj qhov ntswg kho mob thiab N95 qhov ncauj qhov ntswg yog tsim ntawm spunbond txheej, meltblown txheej thiab txheej spunbond. Ntawm lawv, spunbond txheej thiab meltblown txheej yog txhua yam ua los ntawm cov khoom siv polypropylene PP. Muaj ntau cov voids, fluffy qauv, thiab zoo quav kuj. Cov hluav taws xob ultrafine nrog cov qauv tshwj xeeb capillary nce tus naj npawb thiab thaj chaw ntawm cov fibers hauv ib cheeb tsam, kom cov ntaub npuag yaj tau zoo filterability, shielding, kub rwb thaiv tsev, thiab kev nqus roj. Nws tuaj yeem siv rau hauv cov kab ntawm huab cua, cov ntaub ntawv ua kua, cov ntaub ntawv rwb thaiv tsev, cov ntaub ntawv nqus, cov ntaub npog ntsej muag, cov ntaub ntawv siv rwb thaiv tsev, cov khoom siv roj-ua kom zoo nkauj thiab cov nplauv.

Thaum Lub Peb Hlis 8, 2020, Xeev Tuam Txhab Saib Xyuas Cov Khoom Siv Tshawb Xyuas thiab Pawg Neeg Saib Xyuas Haujlwm ntawm Lub Xeev Pawg Neeg Saib Xyuas Hauv Xeev tau tshaj tawm tias thaum muaj kev thov rau cov ntaub yaj txog cov ntaub npog ntsej muag cov ntaub ntawv tseem ceeb, lub Xeev-Lub Tuam Txhab Saib Xyuas Cov Khoom Siv thiab Pawg Tswj Xyuas Haujlwm ntawm Lub Xeev Pawg Saib Xyuas coj cov kev lag luam hauv nruab nrab txhawm rau txhim kho kev tsim cov kab ntau lawm, muab tso rau hauv kev tsim tawm sai li sai tau, thiab nthuav cov yaj cov yaj cov khw muag khoom lag luam. Kev tiv thaiv thiab tswj hwm muab kev tiv thaiv. Raws li SASAC Cov Khoom Siv Kho Mob Tshwj Xeeb Pab Pawg, thaum txog 24 teev thaum Lub Peb Hlis 6, qhov tso tawm ntawm cov ntaub npuag ntawm cov chaw lag luam ua tiav tau txog 26 tons nyob rau hnub ntawd. Raws li cov kab ntau lawm tshiab tau ua tiav thiab muab tso rau hauv kev tsim tawm, cov zis ntawm meltblown cov ntaub yuav tsum nce ntau nyob rau lub lim tiam tom ntej. SASAC thiab cov chaw lag luam hauv nruab nrab yuav txuas ntxiv txhim kho lawv cov dag zog los xyuas kom cov khoom siv kho mob xws li ntaub npog npog chaw tsim tshuaj kho mob.
