Hauv cov txheej txheem tsim khoom ntawmyaj-blown nonwoven, vim yog qhov ntsuas kub, cua siab, pwm, ceev thiab lwm yam ntawm qhov sib piv, yog li qhov xav tau kev khiav tas li thiab debugging, txhawm rau ua kom cov khoom ua tiav qhov zoo tshaj plaws. Cov hauv qab no yog qhov kev paub sau tseg hauv cov txheej txheem ntau lawm rau koj qhov kev siv:
Ib: Cov txheej txheem kho tshuab
1. Ua kom daim ntaub mos dua thaum muaj qhov kub thiab txias dua thiab cua hlob;
2. Maj mam txo qhov kub ntawm lub taub hau tuag thiab qhov kub ntawm huab cua kub kom txog thaum daim ntaub zoo li tawv me ntsis;
3. Sau qhov kub ntawm lub taub hau tuag thiab qhov kub ntawm lub hau ntsia hlau rau lub sijhawm no;
4. Kho qhov cua ntsawj, yaj cov extrusion ntau npaum li cas thiab qhov deb ntawm lub net kom ua rau daim ntaub mos dua;
5. Kho qhov ceev ntawm qhov winding kom ua tiav tag nrho traction;
6, sawv ntsug-ncej raws li qhov ceev ntawm lub grid, feem ntau ntxiv ob sawv ntsug-ncej, static voltage hauv 40KV-60kV, sawv ntsug-ncej bar nrug 5-7 cm daim ntaub nto, maj mam ntxiv ib qho static hluav taws xob tuaj yeem ua tau, koj tuaj yeem xaiv ntxiv qhov zoo, koj tuaj yeem xaiv ntxiv qhov tsis zoo, tuaj yeem txiav txim siab los ntawm kev sim.
Ob: Kho qhov chaw teeb tsa parameter pib
1. Qhov kub ntawm cov ntsia hlau: teem 190 ° C, 230 ° C, 230 ° C..., 230 degrees, 270 degrees (1500 cov khoom yaj tsis pub tshaj 270 degrees, tuaj yeem yog 260 degrees);
2, qhov kub ntawm lub pwm: 252 degrees, 252 degrees..., 252 degrees (feem ntau 240 degrees -255 degrees);
3. Kev hloov pauv sai, twj ntsuas, lim taub hau tuag: 240 degrees;
4. Qhov kub ntawm lub lauj kaub ua kom sov: 300 degrees, qhov kub ntawm huab cua kub: 240 degrees;
5, cua siab: 0.2-0.5mpa (cov khoom siv PP kub qis dav dav, cua siab tuaj yeem xaiv me ntsis me dua, cov khoom siv kub nruab nrab, qhov chaw yaj txog 1300 cua siab tuaj yeem loj dua me ntsis);
6. Qhov nrug ntawm cov ntaub: 15-19 cm;
7. Qhov loj ntawm lub tuyere yog sib xws nrog qhov deb ntawm lub taub hau spinneret mus rau lub dav hlau ntawm rab riam cua, 1-2 hli;
8, qhov ceev ntawm lub hau ntswj yog nruab nrab lossis me me (qhov cua me me, qhov ntim extrusion tuaj yeem me me, qhov cua loj, qhov ntim extrusion tuaj yeem loj).
Peb: kho qhov teeb meem tsis zoo
1. Yog tias daim ntaub tseem tsis mos ntawm qhov kub siab uas pom zoo, tej zaum yuav muaj teeb meem nrog qhov kub thiab txias lossis kev tswj qhov kub thiab txias, ncaj qha txuas ntxiv nce qhov kub kom txog thaum daim ntaub nyob rau hauv lub xeev mos;
2. Yog tias lub zog cua qis dua 0.2mpa thiab qhov kub ntawm lub taub hau tuag yog li lossis qis dua 210 degrees, yuav muaj qhov tshwm sim ntawm paj ya. Nws muaj peev xwm hais tias qhov chaw yaj ntawm PP yaj tsis zoo, lossis qhov kub thiab txias tsis zoo, qhov tso saib lub zog cua tsis zoo, lossis qhov loj me thiab lub kaum sab xis ntawm lub qhov cua tsis zoo, yog li yuav tsum tiv tauj tus neeg tsim khoom siv lossis tus neeg tsim khoom siv raw kom tshem tawm qhov tsis zoo;
3. Nws raug pom zoo kom siv cov khoom siv kub qis rau cov khoom siv loj thiab cov khoom siv kub nruab nrab rau cov khoom siv me me;
4. Feem ntau, yog tias daim ntaub tsis mos thaum nws raug ntxiv rau qhov kub siab, lossis nws pib ua brittle, thiab tom qab ntawd qhov kub ntxiv ntxiv, daim ntaub pib ua mos. Feem ntau hais lus, muaj teeb meem nrog cov khoom siv nws tus kheej, yog li nws raug pom zoo kom tiv tauj lub chaw tsim khoom siv, lossis muaj teeb meem zoo nrog cov khoom siv;
5. Feem ntau, kev ntxiv cov electret masterbatches yuav tsum tau sib phim los ntawm kev kho cov txheej txheem tsim nyog. Cov electret masterbatches sib txawv muaj cov txheej txheem sib txawv, uas tuaj yeem hloov kho rau qhov zoo tshaj plaws raws li cov txheej txheem hloov kho sai no, thiab tom qab ntawd piv rau kev ua tau zoo;
6. Qhov ntau dua ntawm electret masterbatch yog, qhov zoo dua qhov electrostatic effect yuav yog. Txawm li cas los xij, qhov ntau dua ntawm kev cuam tshuam rau daim ntaub yuav yog, yog li nws yog qhov tsim nyog los ua kom muaj kev sib npaug, thiab lub hauv paus ntsiab lus yog ua kom daim ntaub zoo.
Iv. Cov Ntaub Ntawv Thov (Kev teeb tsa kub)
1, qhov kub ntawm lub hau ntswj: 190 degrees, 230 degrees, 230 degrees..., 230 degrees, 260 degrees;
2. Kub ntawm qhov cub: 240 degrees, 240 degrees ... 240 degrees;
3. Kev hloov pauv sai ntawm lub vijtsam, lub twj tso kua mis metering, lub taub hau tuag lim: 245 °;
4. Qhov kub ntawm lub lauj kaub ua kom sov: 300 degrees, qhov kub ntawm huab cua kub: 220 degrees.
Cov fiber yooj yim kom oxidized hauv huab cua, tshwj xeeb tshaj yog thaum kub siab, yog li feem ntau, qhov kub ntawm lub taub hau pwm thiab qhov kub ntawm huab cua kub yuav tsum qis dua, qhov kub ntawm lub hau ntswj yuav tsum siab dua, tib lub sijhawm, qhov chaw lim dej, qhov kub yuav tsum siab dua, yog li txo qhov zaus ntawm kev ntsaws lub taub hau pwm.
Tsib: Ib qho kev piav qhia txog kev txo qis electrostatic
Yuav kom txhim kho qhov ua tau zoo ntawm kev lim cua, kev kho electret thiab kev ntxiv electret masterbatch kuj tseem xav tau los txhim kho lub peev xwm adsorption electrostatic thiab lim cov submicroparticles hauv cov roj carrier kom zoo dua.
1, cov ntaub yaj-blown tom qab ua tiav los ntawm hauv, tshwj tsis yog hauv masterbatch heev tuaj yeem noj electrostatic, cov khoom siv yaj-blown PP kuj tuaj yeem coj electrostatic, ntxiv me me hauv cov masterbatch heev rau ntawm txoj siv ntawm cov nyhuv lim ntawm electrostatic feem ntau yog li 10-20%, thiab electrostatic ruaj khov, nyob rau hauv cov xwm txheej cia khoom tsim nyog, qhov attenuation qeeb, thiab cov khoom siv yaj-blown PP kuj tuaj yeem coj ntau ntawm hluav taws xob static, tuaj yeem ua rau muaj kev cuam tshuam loj heev rau cov nyhuv lim ntawm kev txhim kho, tab sis kuj lwj sai;
2. Qhov txo qis ntawm kev lim dej zoo tsis zoo ib yam li qhov electrostatic attenuation ntawm electret mastermind, tab sis qhov electrostatic attenuation ntawm molten shotcrete PP yuav ua rau qhov kev lim dej zoo txo qis sai;
3. Cov ntaub ua los ntawm qhov kub siab thiab cua kub zoo li mos, tab sis nws qhov tawv tsis txaus. Nrog rau lub sijhawm ntev, cov ntaub yuav tawg thiab ua rau cov nyhuv lim dej txo qis;
Rau: lim cov nyhuv txhim kho debugging txoj kev
1, yog tias koj xav ua kom cov ntaub lim dej ruaj khov, ua ntej tshaj plaws, tsis ntxiv cov masterbatch thiab cov txheej txheem ua haujlwm ntau dhau, qhov xav tau ntawm cov ntaub lim dej yaj-blown yog qhov tseem ceeb dua, vim li no, koj tuaj yeem koom nrog masterbatch, tsis ntxiv cov txheej txheem ua haujlwm, sim cov nyhuv lim dej ntawm qhov sib txawv, zoo hauv masterbatch tsis ntxiv cov masterbatch heev, tseem tuaj yeem tsim los ntawm cov txheej txheem winding ntawm hluav taws xob static, yog li txhim kho cov nyhuv lim dej ntawm cov ntaub yaj-blown;
2. Feem ntau hais lus, qhov kev ua haujlwm ntawm lub cev ntawm cov ntaub txau yaj yuav tsum ncav cuag 60% -80%, thiab tom qab ntawd kev ua haujlwm ruaj khov tuaj yeem ua tiav los ntawm kev ntxiv electret masterbatch thiab electret kho.
Qhov saum toj no yog hais txog: yaj cua tshuab cov ntaub tsis yog woven hloov kho sai, Kuv vam tias yuav muaj qee qhov kev pab rau koj; Peb yog ib tugHoobkas meltblown nonwoven, txais tos los sab laj ~
