Hais txogspunbond non-woven npuag, txhua leej txhua tus yuav tsum paub txog nws vim nws daim ntawv thov ntau yam tam sim no dav heev, thiab nws yuav luag siv ntau yam ntawm tib neeg lub neej. Thiab nws cov ntaub ntawv tseem ceeb yog polyester thiab polypropylene, yog li cov khoom siv no muaj lub zog zoo thiab kub tsis kam. Spunbonded non-woven npuag yog ib hom non-woven npuag uas yog tsim los ntawm extruding thiab stretching polymers los ua nruam filaments, uas yog ces nteg rau hauv ib tug mesh thiab bonded los ntawm nws tus kheej thermal, tshuaj, los yog mechanical txhais tau tias. Nws muaj ntau yam kev siv, thiab cov neeg paub txog cov hnab ntim tsis-woven, tsis-woven ntim, thiab lwm yam. Thiab nws kuj yog ib qho yooj yim heev los txheeb xyuas, feem ntau nws muaj kev ruaj ntseg zoo, thiab nws cov ntsiab lus dov yog pob zeb diamond zoo li.
Daim ntawv thov Scope
Daim ntawv thov theem ntawmspunbond tsis woven ntaubkuj tseem siv tau los ua ib feem ntim rau paj thiab cov ntaub ntim tshiab, thiab lwm yam. Thiab nws kuj yog siv dav hauv kev ua liaj ua teb sau ntaub. Nws kuj muaj nws lub xub ntiag nyob rau hauv kev kho mob thiab kev lag luam cov khoom pov tseg, rooj tog zaum hauv ob sab phlu, thiab cov khoom siv tu cev hauv tsev so. Yog li. Imitation adhesive non-woven npuag muaj ntau yam ntawm cov nplai thiab yog tsim los ntawm kev siv lub siab zoo. Vim yog txoj kev no, kev sib txuas ntawm cov khoom sib txuas, thiab cov khoom tsim los ntawm kev siv lub tshuab nqus tsev vacuum yog ntxhib heev, uas ua rau tsis muaj fiber ntau stretching ntawm ib zaug. Qhov no yog vim li no, nws tsis tuaj yeem tsim cov khoom siab tshaj 120 grams ib square meter.
Yuav ua li cas kom tsis woven ntaub
Thiab cov txheej txheem ntau lawm tuaj yeem hloov kho tau yooj yim. Lub thawv spinning ntawm cov khoom sib koom ua ke yuav siv ntau lub twj tso kua mis ywj siab los ntsuas cov yaj. Thiab txhua lub metering twj tso kua mis muab tag nrho cov khoom siv rau ib tus naj npawb ntawm cov khoom siv spinning. Vim li no, lub twj tso kua mis metering tuaj yeem nres raws li tus neeg siv khoom xav tau hauv kev tsim khoom, thiab tom qab ntawd lub baffle ntawm lub tshuab textile tuaj yeem hloov kho los tsim cov khoom lag luam ib nrab ntawm qhov dav sib txawv. Tsis tas li ntawd, thaum qee qhov kev taw qhia ntawm cov khoom lag luam ib nrab ua tiav tsis tau raws li cov qauv, cov khoom siv textile sib raug tuaj yeem hloov kho.
Dab tsi yog cov txheej txheem yooj yim ntws ntawmspunbond nonwoven ntaub?
1. Txiav thiab ci
Cov chips polymer tau txais los ntawm granulation thiab casting ntawm kev sib kis txoj siv tawv feem ntau muaj qee qhov dej noo, uas yuav tsum tau qhuav thiab tshem tawm ua ntej spinning.
2. Kiv cua
Cov cuab yeej spinning thiab thev naus laus zis siv hauv txoj kev spunbond yog qhov pib zoo ib yam li cov siv tshuaj fiber ntau spinning. Cov khoom siv tseem ceeb thiab cov khoom siv yog ntsia hlau extruders thiab spinnerets.
3. Stretch
Cov txheej txheem tshiab yaj spun fibers (thawj fibers) muaj lub zog qis, siab elongation, cov qauv tsis ruaj khov, thiab tsis muaj qhov ua tau zoo uas yuav tsum tau ua rau textile ua, yuav tsum tau ncab.
4. Filamentation
Lub npe hu ua splitting yog hais txog kev sib cais ntawm cov khoom siv fiber ntau rau hauv ib qho fibers los tiv thaiv fibers los ntawm kev nplaum los yog knotting thaum lub sij hawm tsim lub web txheej txheem.
5. Tso lub vas
(1) Cua ntws tswj
(2) Mechanical tiv thaiv thiab tswj
(3) Tom qab ncab thiab sib cais, cov filament yuav tsum tau muab sib npaug rau ntawm daim ntaub thaiv.
6. Suction net
Los ntawm kev siv suction nets, lub downward airflow tuaj yeem nqa mus thiab qhov rov qab ntawm tus cab tuaj yeem tswj tau. Yog li ntawd, muaj 20 centimeter tuab ntsug cua qhia orifice phaj nyob rau hauv lub mesh curtain kom tsis txhob rov qab airflow los ntawm tshuab mus rau lub mesh. Ib khub ntawm windproof rollers yog teem rau ntawm suction ciam teb rau pem hauv ntej kev taw qhia ntawm lub fiber mesh. Cov menyuam sab sauv muaj ib txoj kab uas loj dua, yog tus du, thiab nruab nrog rab riam ntxuav kom tsis txhob muaj cov menyuam los ntawm kev nkag mus. Cov menyuam yaus hauv qab muaj lub taub me me thiab feem ntau yog clamped nrog cov menyuam roj hmab los ua ib daim ntaub thaiv. Lub auxiliary suction ducts ncaj qha nqus hauv airflow siab net, yog li tswj cov fiber ntau txuas mus rau cov ntaub thaiv npog.
7. Kev txhawb zog
Kev txhawb zog yog cov txheej txheem kawg, uas ua rau cov mesh muaj qee lub zog, elongation, thiab lwm yam khoom kom tau raws li cov khoom xav tau.
Yog tias qhov ua tsis taus pa tsis zoo, cov pab pawg spinning nrog tsawg qhov ntawm lub spinneret tuaj yeem hloov tau, uas tuaj yeem ua rau kom ua pa ntawm cov ntaub nto. Tam sim no, huab cua siab ntawm ib-txoj kev qhia lub tog raj kheej kuj tuaj yeem hloov kho kom lub cev muaj zog ntawm tag nrho qhov dav ntau dua. Lub zog sab nraud ntawm spunbond non-woven npuag yog qhov siab, thiab txoj kev spinning siv txoj kev textile los tsim lub vev xaib. Daim ntawv yuav tsis tu ncua viav vias rov qab thiab tawm ntawm qhov zaus ntawm 750Hz, thiab lub siab ceev stretching fibers yuav sib tsoo tom qab nrog cov mesh.
Lub zog ntawmspunbond ntaubyog siab heev vim lub mesh curtain txav mus rau pem hauv ntej diagonally thiab interlaces. Qhov ntsug thiab kab rov tav siv ntawm cov ntawv tuaj yeem ncav cuag 1: 1. Feem ntau hais lus, kev simulation siv lub Venturi riser, tab sis nws lub zog tsis siab dhau, thiab lub zog ntev thiab transverse muaj zog heev. Cov fibers ntawm non-woven fabrics nyob rau hauv cov websites muaj zoo kub-resistant thiab hnav tsis kam, thiab lawv mechanical zog yog ntau dua li ntawm PP fibers.
Dab tsi yuav tsum tau them sai sai rau thaum lub sij hawm dov txheej txheem ntawm spunbond non-woven npuag?
1. Thaum lub sij hawm winding txheej txheem, tswv lub nro tswj ntawm spunbond non-woven npuag.
2. Thaum lub nro nce nyob rau hauv ib tug tej yam ntau yam, txoj kab uas hla thiab dav ntawm lubspunbond nonwoven yobntsws.
3. Thaum qhov nro nce nyob rau hauv ib qho chaw, nws tuaj yeem nce ntxiv. Qhov kev xav tau tiag tiag rau qhov nro saum toj no yuav tsum tau sau tseg hauv cov khoom siv tiag tiag kom ntseeg tau tias qhov zoo.
4. Thaum lub sijhawm tsim khoom, ua tib zoo saib xyuas qhov dav thiab yob ntev ntawm spunbond non-woven npuag.
5. Daim ntawv raj thiab spunbond non-woven npuag yob yuav tsum tau ua raws li.
6. Ua tib zoo saib xyuas qhov zoo ntawm spunbond non-woven npuag, xws li dripping, breakage, tearing, thiab lwm yam.
7. Ntim raws li qhov yuav tsum tau ua, ua tib zoo saib xyuas kev huv, thiab xyuas kom lub ntim ruaj khov.
8. Kev kuaj thiab kuaj ntawm txhua pawg ntawm spunbond non-woven npuag.
