Kev sib xyaw ua ke ntawm cov khoom siv yaj

Melt blown fabric yog ib qho nplaum thiab npog cov ntaub ntawv uas tau txau rau saum npoo tom qab cov ntaub ntawv tshwj xeeb yog melted siv dav hlau tshuab. Nws cov hauv paus ntsiab lus thiab cov txheej txheem tuaj yeem siv los tsim cov duab zoo, uas yog lub hauv paus ntawm 3D luam ntawv. Nws cov ntaub ntawv tseem ceeb suav nrog carbonates, latex, polyurethane, polyvinyl cawv, polymer hmoov, thiab polyvinyl chloride, ntawm cov khoom siv feem ntau yog cov hmoov yas, xim tsheb, iav, thiab lwm yam.

Lub Cheebtsam ntawm yaj cua tshuab tau muab faib ua peb pawg: cov khoom siv hauv paus, additives, thiab catalysts. Cov ntaub ntawv hauv paus xa mus rau cov ntaub ntawv tseem ceeb uas muaj kev faib ua feem ntau hauv cov khoom siv yaj, feem ntau suav nrog nylon, polycarbonate, polystyrene, polyurethane, thiab lwm yam. Lawv tuaj yeem muab cov yam ntxwv yooj yim xws li lub zog, hnav tsis kam, thiab ductility ntawm yaj cua tshuab.

Cov additives feem ntau koom nrog fillers, lubricants, thiab anti stripping agents, ntawm cov fillers tuaj yeem txhim kho lub hardness ntawm yaj cua tshuab, thaum lubricants tuaj yeem ua rau cov khoom zawv zawg ntawm cov khoom tawg. Anti stripping agents pab ua kom cov adhesion ntawm yaj cua tshuab, ua rau lawv tsis tshua muaj detachment. Feem ntau hais lus, cov ntsiab lus ntawm cov khoom siv ntxiv rau 5% mus rau 15% ntawm tag nrho cov nyiaj ntawm cov ntaub yaj.

Thaum kawg, cov catalysts pab ua kom nrawm nrawm ntawm cov khoom siv yaj yaj, txhim kho lawv cov hardness, hloov lawv cov qauv, thiab ua kom lawv adhesion. Kev sib txawv catalyst ua ke tuaj yeem kho qhov ceev nrawm lossis hardness ntawm cov khoom siv yaj kom tau raws li qhov xav tau ntawm cov ntawv thov sib txawv. Feem ntau hais lus, cov ntsiab lus catalyst tso nyiaj rau 1% mus rau 5% ntawm tag nrho cov nyiaj ntawm cov ntaub ntawv yaj.

Melt blown ntaub muaj ib tug nplua nuj muaj pes tsawg leeg, thiab txhua hom raw khoom thiab additive muaj nws tus kheej muaj nuj nqi. Los ntawm kev kho qhov sib piv ntawm ntau yam raw cov ntaub ntawv thiab additives thiab txawv catalyst pawg, meltblown ntaub tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb, thiab nws siv kuj yog qhov dav heev, uas hloov peb lub neej dua.

Melt blown ntaub yog dav siv nyob rau hauv kev lag luam thiab tsev neeg vim nws ntau yam zoo. Piv txwv li, hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob yaj tuaj yeem siv los tiv thaiv cov khoom siv hluav taws xob, txo qhov kev laus ntawm cov khoom siv hluav taws xob, thiab tiv thaiv kev cuam tshuam ntawm plua plav thiab dej; Hauv kev kho kom zoo nkauj hauv tsev, daim ntaub meltblown tuaj yeem siv los tiv thaiv cov plag tsev thiab phab ntsa, tiv thaiv phab ntsa puas; Meanwhile, yaj cua tshuab tuaj yeem siv los ua txhua hom ntim thiab npog cov ntaub ntawv, casting pwm, lub cev tsheb, thiab lwm yam.

Melt blown npuag tuaj yeem tsis tsuas yog hloov cov duab, tab sis kuj tseem txhim kho cov khoom nto, xws li kev txhim kho qhov muag pom kev, txo tus nqi ntawm qhov foaming, txo dielectric poob, txhim kho roj thiab corrosion kuj, yog li txuas ntxiv kev pab cuam lub neej ntawm cov khoom thiab txhawb kev txhim kho kom ruaj khov.

Melt blown fabric yog ib yam tshiab ntawm cov khoom uas nyuaj los hloov, thiab nws cov kev cia siab yog heev. Nws tuaj yeem siv rau hauv ntau qhov chaw, los ntawm kev ntim khoom siv hluav taws xob mus rau kev kho kom zoo nkauj hauv tsev, txhua yam ua tau. Nyob rau tib lub sijhawm, qhov saum npoo ntawm cov ntaub nplaum yaj muaj qhov ua haujlwm siab corrosion thiab hnav tsis kam, uas tuaj yeem tiv thaiv kev cuam tshuam ntawm qhov chaw ntub dej. Nws tuaj yeem hais tau tias daim ntaub yaj yaj tau hloov peb txoj kev ua neej. Nyob rau hauv lub neej yav tom ntej, nws tseem yuav ua si ntau lub luag haujlwm thiab ua cov khoom tseem ceeb hauv ntau qhov chaw.
