Electrostatic polarization tshuab
Cov khoom siv los ua cov lim cua electret yuav tsum muaj cov khoom siv zoo tshaj plaws, xws li lub cev muaj zog thiab kev tiv thaiv saum npoo, siab dielectric tawg lub zog, tsis tshua muaj noo noo nqus, thiab huab cua permeability.
Cov khoom siv no feem ntau yog tsim los ntawm cov ntaub ntawv polymer organic polar siab, xws li cov ntaub ntawv tsis muaj polar xws li polypropylene, polytetrafluoroethylene, hexafluoropropylene / tetrafluoroethylene copolymer, thiab lwm yam; Polar los yog tsis muaj zog polar cov ntaub ntawv: Polytrifluoroethylene, polypropylene (blend), polyester, thiab lwm yam.
High melting point polypropylene resin tau dhau los ua cov khoom siv rau cov tshuab electrostatic yaj vim nws cov kev ua tau zoo heev, tus nqi qis, thiab zoo polarizability. Txawm li cas los xij, hauv kev xyaum, nws lub peev xwm khaws cia electrostatic cuam tshuam zoo heev los ntawm cov yam ntxwv xws li qhov kub thiab txias, av noo, thiab lub sijhawm cia, uas ua rau pom tsis ruaj khov.
Txhawm rau kom nkag siab txog cov kev hloov pauv ntawm tus nqi them, them ceev, them nyiaj ruaj khov nyob rau hauv cov xwm txheej sib txawv, pom kev ua haujlwm zoo, thiab qhov hluav taws xob poob ntawm cov nqi zoo li qub nyob rau saum npoo ntawm meltblown fabrics, cov kws tshawb fawb hauv tsev thiab txawv teb chaws tau tshawb fawb ntau ntawm cov txheej txheem polarization thiab polarization masterbatch technology.
Fluorine yog lub caij nrog lub siab tshaj plaws electronegativity thiab muaj peev xwm loj tshaj plaws rau "tau txais electrons". Cov hluav taws xob ntes los ntawm fluorine atoms tsis yooj yim khiav tawm thiab tuaj yeem txhim kho qhov pom kev ua haujlwm zoo thiab kev pabcuam lub neej ntawm cov ntaub ntawv lim.
Nrog kev pab los ntawm ntau yam plasma electrostatic technologies xws li AC corona los yog DC corona, ib nrab saturated fluorine atoms yog ionized, thiab nyob rau hauv tej yam kev mob, cov fluorine hais txawm ib feem ua ke nrog polypropylene fibers los ua dab tsi hu ua "hybrid" cov ntaub ntawv nyob rau hauv lub scientific kev tshawb fawb teb.
Cov tsev kawm ntawv hauv tsev xws li Donghua University tau ua qhov kev tshawb fawb tob txog kev ua haujlwm pom ntawm cov khoom siv sib xyaw no hauv polypropylene meltblown fabrics.
Ultra nplua Organic Fluorine Electret Powder TF11
Ultra nplua organic fluorine polarizing hmoov TF11 muaj lub peev xwm electrostatic siab heev, thiab tuaj yeem txhim kho kev pom zoo los ntawm kev ntxiv 0.05-0.2% rau cov ntaub ntawv meltblown. Nws yog tsuas yog siv nyob rau hauv zus tau tej cov meltblown fabrics nrog pom efficiency ntawm 95 los yog 99.
Piv nrog rau lwm cov ntaub ntawv inorganic hmoov, ultrafine organic fluorine hmoov nws tus kheej muaj lubricity thiab zoo compatibility nrog polypropylene cob, ua rau nws kuj yooj yim los tsim polar masterbatch thiab tsis tshua muaj yuav clog lub spinneret.
Tianshi TF11 organic fluorine polar hmoov yog zoo heev thiab muaj ib tug siab melting point, uas yuav pom tau raws li ib tug muab tub lim thaum lub sij hawm qhuav txheej txheem. Tsis zoo li qee cov ntaub ntawv uas muaj fluorine uas tau hais hauv cov ntaub ntawv, TF11 nws tus kheej tsis yog fibrose, thiab ib qho ntxiv me ntsis yuav tsum tsis txhob cuam tshuam qhov zoo ntawm cov yaj yaj fibers.
Cov khoom sib xyaw ntawm Tianshi TF11 thiab Molten Finger 1500 PP tau siv los ua kom tau txais lub ntsej muag masterbatch. Tus nqi ntawm TF11 ntxiv rau lub ncov qaumteb qabteb masterbatch yog 5-10%, thiab qhov xwm txheej ntxiv kuj tseem cuam tshuam nrog cov txheej txheem tshwj xeeb ntawm cov khoom siv. Nyob rau hauv txoj cai, ib tug me ntsis qis extrusion kub yuav ua rau nws yooj yim dua.
Los ntawm kev sib xyaw nrog PP hmoov, 5-15% ntawm Tianshi TF11 organic fluorine polar hmoov tuaj yeem ncaj qha ntxiv thaum lub sij hawm tsim cov index 1500 PP ncaj qha tsim cov polar masterbatch.
Lub ncov qaumteb qabteb masterbatch ua raws li cov txheej txheem saum toj no yog ntxiv nrog 1-3% nyob rau hauv cov mis yaj tshuab, los yog cov ntsiab lus ntawm Tianshi TF11 yog xam los ntawm 0.1-0.2%.
Qee cov neeg siv khoom kuj tau sim ntxiv 0.2% Tianshi TF11 organic fluorine polar hmoov rau PP hmoov los ntawm kev sib xyaw ua ntej masterbatch thiab lwm txoj hauv kev los tsim cov ntsiab lus melting siab yaj cov ntaub ntawv nrog cov khoom siv polar built-in.
Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom. Nws tuaj yeem tsim ntau yam xim ntawm PP spunbond non-woven fabrics nrog qhov dav ntawm tsawg dua 3.2 meters los ntawm 9 grams mus rau 300 grams.
