Los ntawm cov khoom siv raw mus rau cov khoom siv
Txhua txoj kev ua yog qhov tseem ceeb heev
Txawm tias tsuas muaj cov yam ntxwv ntawm tus kheej xwb los xij
Qhov zoo ntawm cov khoom kawg kuj tuaj yeem sib txawv heev
Tom qab Razer tshawb nrhiav tob tob thiab rov ua dua qhov kev sim
Cov ntaub tsis-woven uas yaj tau txog li N95+
Yim thaj chaw hauv qab no yuav tsum tau tswj hwm nruj me ntsis
Tam sim no nrog txhua tus neeg ua tib zoo saib xyuas
cov khoom siv yaj
1. Nws muaj ntxhiab tsw qab tsawg, cov tshauv tsawg, cov metric siab thiab cov khoom faib molecular nqaim.
2. Muaj nyiaj ntau dua.
3. kev ua tau zoo ntawm cov fiber ntau, tuaj yeem ua rau cov fiber ntau dua, cov hlau txoj kab uas hla me dua.
4. cov ntaub txhob lo lo ntxhuav tas mus li, cov khoom poob, qhov tig tau zoo dua.
5. yooj yim siv, ua haujlwm ruaj khov dua.
6. Nws tuaj yeem siv rau kev tsim cov khoom siv lim dej, paj rwb uas nqus roj, cov khoom siv pabcuam khaub ncaws, roj teeb diaphragm thiab lwm yam kev siv ntawm cov txheej txheem yaj.
yuav ua li cas ua daim ntaub yaj
1. Cov fiber yuav tsum zoo, qhov nqi yaj ntawm cov khoom siv raw thiab lub cheeb ntawm spinneret phaj raug phim, thiab cov txheej txheem spinneret raug kho kom zoo, yog li ntawd cov fiber ncav cuag 0.3um.
2. kom phim cov khoom siv electret zoo thiab xaiv cov khoom siv electret masterbatch zoo. Ib qho khoom siv electret master zoo yuav tsum muaj peev xwm khaws cov nqi thiab tsim kom muaj hluav taws xob tas mus li.
3. Lub sijhawm siv tau ntawm lub npog ntsej muag hauv electret feem ntau nyob ntawm cov ntsiab lus ntawm electret masterbatch. Electret masterbatch zoo ib yam li roj teeb, ntxiv qhov sib piv yuav txiav txim siab nws lub neej thiab lub peev xwm nqus.
4. Ziab daim ntaub uas yaj tawm thiab khaws cia. Nws tsis tuaj yeem sib cuag nrog cov av noo ntawm huab cua sab nraud. Qhov zoo tshaj plaws yog ntim nrog lub tshuab nqus tsev. Cov av noo hauv huab cua thiab cov nqi hluav taws xob hauv daim ntaub uas yaj tawm yuav hloov mus ua cov ions tsis zoo, thiab qhov poob ntawm cov nqi hluav taws xob yuav cuam tshuam rau kev ua haujlwm ntawm kev lim dej.
3. Vim li cas ho tsis zoo rau cov ntaub yaj uas tsis zoo
1. Cov khoom siv Spinneret thiab cov khoom siv yaj
2. cov khoom siv hluav taws xob electrostatic
3. cov khoom siv hluav taws xob electrostatic electret ntev
4. cov khoom siv tshuaj tsuag lossis cov khoom siv fiber ntau ntiv tes yaj
5. tus kws tshaj lij thiab kev paub txog kev kho tshuab
6. Kev tswj hwm qhov chaw ntawm cov khoom siv yaj-tshuab
yuav ua li cas xaiv cov khoom siv yaj-blown
1. yaj: polypropylene los ntawm kev ntxiv peroxides thermal degradation lossis metallocene hydrogen kev hloov kho txoj kev, polypropylene yaj kom ncav cuag qib siab tsim nyog, tuaj yeem tsim cov nanoscale fiber.
2. Lub melting point ntawm cov khoom me me yuav tsum tau txo kom txog li ntawm 150-170 ° C.
3. Tom qab ntxiv cov khoom meltret master, daim ntaub meltblown yuav tsim cov kev ua haujlwm electrostatic adsorption los ntawm lub cuab yeej electret los thaiv cov kab mob.
4. Tom qab kev hloov kho ntawm cov khoom polypropylene, cov fiber uas raug rho tawm los ntawm lub tshuab ntaub yaj ntawm qhov kub thiab siab yog qhov zoo thiab ntev.
5. Cov kua dej uas raug rho tawm ntawm cov khoom siv raw uas nws tus kheej yaj yog mos, tawv thiab khov kho.
6. kev ua kom sov siab.
electret master batch xaiv
1. lub sijhawm thauj khoom electrostatic, seb puas tuaj yeem them ntev txog 1 xyoos lossis ntau dua.
2.electret masterbatch tsis txuas lub qhov meltblown, meltblown daim ntaub thauj khoom them, yuav ua li cas thiaj ua rau lub nqi zoo nyob ntev rau ntawm daim ntaub meltblown, tuaj yeem
Tom qab ib nrab xyoo lossis tom qab ib xyoos tsis muaj kev poob nqi, dhau los ua qhov kev xeem electret master batch thiab electret txheej txheem tseem ceeb index.
3. Lub voj voog thaiv ntev, lub zog hluav taws xob ntev, PFE tshaj 95.
Kev kho cov txheej txheem electrot
1. Daim ntawv thov tseem ceeb feem ntau yog txoj kev them nqi corona rau kev kho hluav taws xob ntawm cov ntaub yaj. Kev them hluav taws xob, lub sijhawm them, kev them deb thiab cov av noo ib puag ncig txhua yam muaj feem cuam tshuam rau cov nyhuv ntawm kev kho hluav taws xob.
Qhov hluav taws xob them muaj qhov cuam tshuam pom tseeb tshaj plaws rau cov nyhuv electret, qhov deb them muaj qhov nruab nrab, thiab lub sijhawm them muaj qhov cuam tshuam tsawg tshaj plaws. Ua tib zoo saib thaum kho lub tshuab.
2. Qhov av noo ntawm ib puag ncig muaj feem cuam tshuam rau kev tsim hluav taws xob thiab kev poob ntawm hluav taws xob zoo li qub. Lub tuam txhab ua ntaub yaj yuav tsum saib xyuas qhov kub thiab av noo hauv lub chaw ua haujlwm txhua lub sijhawm. Ua kom cov khoom siv sib xws kom khaws qhov kub thiab av noo hauv lub chaw ua haujlwm kom nyob hauv qee qhov ntau.
cov khoom siv yaj
1. Yog tias cov polypropylene meltblown nyob twj ywm ntawm qhov kub thiab txias ntev ntev, nws yooj yim rau sinter thiab carbonize.
2. Thaum kho qhov kub ntawm lub tshuab, ua ntej tshaj plaws, nws yog qhov tsim nyog los txiav txim siab seb qhov kub tiag tiag ntawm lub thoob thiab lub pwm ntawm lub tshuab yaj puas sib xws nrog qhov kub teem tseg. Feem ntau cov khoom siv yaj me me tso saib qhov kub thiab qhov kub tiag tiag yuav txawv heev.
3.melting hais txog 1500 polypropylene, yog tias qhov kub thiab txias tau teeb tsa ntau dua 270 ℃, me ntsis siab.
Kev xaiv cov khoom siv yaj
1. Qhov kev teeb tsa yuav tsum ua tiav: extruder → screen changer (lim) → metering twj → tuag taub hau → faib phaj (auxiliary hot air) → spinneret → mesh device los ua daim ntaub yaj.
2. qhov ceev ntawm extruder, cov kev ntsuas ntawm lub twj tso kua mis metering, qhov zoo thiab qhov tsis zoo ntawm lub taub hau tuag, qhov kub thiab qhov ceev ntawm cov cua kub ntws, lub kaum sab xis ntawm lub taub hau tuag, lub kaum sab xis ntawm lub hniav cua, qhov deb ntawm cov khoom siv yaj-blown, cov kev ntsuas adsorption nyob rau hauv lub cuab yeej tsim lub vas thiab lwm yam ua ke txiav txim siab qhov zoo ntawm cov ntaub txau yaj.
Cov saum toj no yog cov txheej txheem tsim cov ntaub tsis-woven uas yaj. Peb yog cov chaw tsim khoom tsis-woven, Huizhou Jinhaocheng Non-woven Co., Ltd. Kuv vam tias tsab xov xwm no tau pab tau koj.
