Nyob rau hauv cov toj roob hauv pes dynamic ntawm cov ntaub ntawv tshaj lij engineering,Meltblown Ntau LawmSawv ntsug ua pob kws ntawm kev tsim kho, kev tsav tsheb vim kev tsav ntawm kev lim dej, kev kho mob, thiab kev siv cov ntawv thov. Qhov kev tsim hluav taws xob siab hloov kho cov txheej txheem hloov hluav taws xob nyoos rau hauv ultra-nplua fibers, tsim cov ntaub ntawv liMeltblown lim cov khoom siv me me, Kev ua raws li purtration pp meltblown daim ntaub, thiabQhuav tshuab rau n95 lub tshuab ua paCov kev daws teeb meem ntawd redefine qauv. NtawmWeston Nonwoven, peb muaj kev pab txiav-ntug kev siv tshuab thiab ntau xyoo ntawm kev txawj ntse rau engineer meltblown cov ntaub ntawv uas sib txuas ua ke, ua tau zoo, thiab kev ruaj khov. Hauv qab no, peb delve mus rau hauv kev tshawb fawb, theem, thiab lub ntiaj teb tiag tiag cuam tshuam ntawm cov txheej txheem hloov chaw no.
Cov theem ntawm meltblown ntau lawm
Cov txheej txheem mellodown yog lub rooj zaum ntawm engineering precision, blendody thermal, aerodynamic, thiab kev tshawb fawb txuj ci. Cia peb tshawb nws txog tsib ntu theem pib:
1. Polymer npaj: lub hauv paus ntawm qhov zoo
Cov lus pib nrog xaiv hwmMeltblown lim cov khoom siv me me, Feem ntau polypropylene (PP) -a polymer nto moo rau nws cov cua sov ruaj khov, tshuaj lom neeg kuj, thiab tus nqi them ua haujlwm. Weston Nonwoven cov peev txheej High-Purity PP pellets nrog nruj tswj tau qhuav ntsuas ntsuas (mfi), ua kom muaj kev sib dhos hauv cov qauv molecular. Qhov kev xaiv tsis zoo no yog qhov tseem ceeb, raws li impurities lossis inconistent melting tus cwj pwm tuaj yeem cuam tshuam cov khoom kawg thiab kev siv hluav taws xob.
Vim li cas pp?
Thermal resilisence: PP withstands extrusion kub ntawm 240-260℃yam tsis muaj kev nyuaj siab.
Hydrophobic Xwm: Npleem noo noo, zoo tagnrho rau cov ntsej muag kho mob thiab cov ntxaij vab tshaus.
Muaj zog: Siv dua tshiab thiab lub teeb ci dua thiab lub teeb ci, ua raws li Weston lub eco-conccess txoj kev mus kom ze.
2. Melting thiab Extrusion: Hloov cov khib nyiab rau hauv cov kua ntsuas
Lub pp pellets nkag mus antsia hlau extruder, qhov twg lawv tau rhaub thiab kneaded rau hauv lub xeev molten. Qhov voscous polymer yaj yog tom qab ntawd yuam dhau los ntawm aLim PobTxhawm rau tshem tawm cov paug, ua kom muaj txiaj ntsig pristine. Weston ua haujlwm tshaj lij extrusion tshuab nrog kev yoog raws kev tswj hwm kub, optimatingzizing melt viscosity rau kev tsim fiber zoo sib xws.
Kev tsim kho hauv kev nqis tes ua:
Weston tus tswv ntawv Extrusion Technology ua tiav homogeneity melt homideneity tsis pub dhau 99.9% precision thaum minimizing siv hluav taws xob. Qhov no tsis tsuas yog txo cov kev cuam tshuam ib puag ncig tab sis kuj ua kom txhua pob ua tau raws li cov qauv coj los ua kom nruj.
3. Fiber ntau: Kos duab ntawm kev ceev nrawm aerodynamics
Molten pp yog pumped los ntawm ameltblown tuag-a precision-engineered phaj nrog ntau pua ntawm lub microscale or (0.1-0.4 hli inch). Nyob rau theem no,High-velocity kub cua(txog li 550 m / s) blasts los ntawm kev tuag, ncab cov dej ntws molten rau hauvultrafine fibers(1-5 microns hauv cov cheeb tsam) -thininner tshaj li tib neeg cov plaub hau.
Science ntawm ncab:
Airflow muaj zog: Ntau dua huab cua ua kom tiav cov nplua nuj finer fibers, txhim kho thaj tsam thaj chaw rau kev lim.
Jetting Tshuab: Weston Tus Poj Niam Tuag TsimAngled Cua Raws, Tsim kev muaj huab cua hlob uas cuam tshuam nrog cov pob txha clumping thiab txhawb nqa cov kev xa tawm cov khaub ncaws tsis zoo.
4. Lub web tsim: weaving ib tug tiv thaiv network
Cov pa taws ua ke tau muab tso rau hauv aMus Siv Congtorlossis sib hloov nruas, sib sau ua ib lub vev xaib, peb-seem. Qhov Web tus qauv-xoob tau cuam tshuam-muab cov ntaub ntawv meltblown lawv kos npe porosity thiab lub zog. Sab hnub poobKev tsis zoo lub nruab nrabTxhawm rau siv zog fiber ntau, kom tuab tuab thiab ceev hla lub vev xaib.
Ntsiab Lus: Qhov hnyav
Lub Web lub nra rau ib cheeb tsam (GSM, grams ib square meter) dictates nws kev ua tau zoo:
15-25 gsm: Lub teeb nyem rau lub qhov ntswg breathable.
50-100 GSM: Hnyav-luag haujlwm rau cov ntxaij lim dej.
5. Kev Ua Haujlwm thiab Tom Ntej Ua: Xauv Hauv Kev Ua Haujlwm
Thaum cov fibers fuse ib txwm nyob thaum txias, cov txuj ci ntxiv tuaj yeem txhim kho cov qauv txheej txheem kev cai:
Qhov Kev Sib Laj Thermal: Tshav kub kub thiab siab yaj yaj yaj sib tshuam sib tshuam, txhim kho lub sijhawm ntev.
Kev Kho Hluav Taws Xob: Ib qho kev ua si-kev ua si rau kev lim dej, cov nqi no tsub nrog hluav taws xob zoo li, ua rau lawv nyiam thiab cov rog tawm ntawm cov tub hauv hluav taws xob.
Weston ntug:
Sab hnub poobDual-theem Electret Systemua ke corona tso nrogNANO-Engineered Additives(piv txwv li, ncig xyuas kev sib tw) kom ua kom tiav luv nqi. Qhov no ua rauKev ua raws li purtration pp meltblown daim ntaubUas tswj 95% + + particle ntes kev ua haujlwm txawm tias tom qab siv ntev.
Qhov kev kawm txuj ci tom qab kev lim heev pp meltblown daim ntaub
Kev ua raws li purtration pp meltblown daim ntaubYog tus pinnacle ntawm meltobrd innestation, engineered kom sib npaug pom kev uas muaj pa. Ntawm no yog dab tsi ua rau nws zam:
1. USTRA-TXOJ KEV ZOO TSHAJ FAIS
Nrog diameters uas me me li 1 micron, cov fibers tsim cov ntom ntom, tortuous network uas lub cev thaiv lub cev. Lawv cov cheeb tsam siab (txog li 30 m² / g) Ampifies Electrostatic, ntes txawm tias submicronic paug zoo li cov kab mob thiab ua xua.
2. Client Density tsim
Weston lub tswv yimFawmts QauvNta denser nyob rau hauv cov txheej txheej rau kev lim thiab cov xoob xoob txheej kom zoo rau airflow. Cov qauv tsim no ua kom tiav:
Siab lim kev: >95% Kev tshem tawm cov particle ntawm 0.3 microns 0.3.
Tsis tshua muaj siab poob: Txo airflow tiv taus rau xis hnav hauv lub ntsej muag lossis lub zog siv hluav taws xob.
3. Hydrophilic Txheej
Kev xaiv cov hmoov txhuas txhim kho cov zaub mov zoo, ua cov khoom zoo rau cov ntawv thov (tawm tsam cov roj lim dej) lossis cov roj cua (pleev roj).
Ntshai cua tshuab rau N95 Lub cev nqus dej: Ib qho kev tiv thaiv paradigm ntawm kev tiv thaiv
TusLub looj ntsej muag ua pa n95teeb tsa cov qauv kub rau kev pom kev lim dej, thiabQhuav tshuab rau n95 lub tshuab ua paCov ntaub ntawv yog nws lub siab ntaus lub plawv. Weston N95-qib Meltblown Daim ntaub ua ke:
Tuam Tshoj Hluav Taws Xob: Them cov fibers nyiam cov ntsiab ntawm cov rog hauv hluav taws xob, them nyiaj rau cov kab hauv lub cev.
Multium-txheej: Feem ntau cov khaubncaws sab nraud povtseg-ob lub spunbond txheej rau lub zog thiab nruab nrab ntawm meltbler tawm tsam 95% ntawm cov pa hluav taws xob ntau dua los yog sib luag rau 0.3 microns.
