Polypropylene spunbond nonwoven jira rudzi rutsva rwezvinhu zvakagadzirwa kubva kunyungudutswa polypropylene kuburikidza nemaitiro akadai sekuruka, mesh kuumba, kutema, uye kuumbwa. Polypropylene spunbond nonwoven jira rine zvakanakisa zvemuviri uye zvemuchina zvivakwa, uye rinoshandiswa zvakanyanya muminda yakadai sekuvaka, hutano hwehutano, hutsanana, midziyo yemumba, uye mota.
Kuyerera kwekugadzira machira asiri akarukwa kubva kupolypropylene: kudyisa kwepolymer - kunyungudika extrusion - kugadzirwa kwefiber - kutonhora kwefiber - webhu kuumbwa - kusimbisa mumucheka.
Yakadzama sumo yekuyerera kwemaitiro ekugadzira machira asina-akarukwa kubva ku polypropylene:
Sanganisa polypropylene uye additives zvakaenzana mumusanganisi, uye wedzera musanganiswa unoguma kune feeder mune extruder (senge twin-screw extruder). Izvo zvinhu zvinopinda mapatya-screw kuburikidza ne feeder, inonyungudutswa uye yakasanganiswa zvakaenzana ne screw, extruded, granulated, uye yakaomeswa kuti iwane isina-yakarukwa jira raw material pellets; Zvadaro, iyo isiri-yakarukwa jira raw material pellets inowedzerwa kune imwechete screw extruder yekunyungudusa nekusanganisa, extrusion, kutenderera kwemhepo kutambanudza, kutonhora uye kusimba, mesh kuisa, uye kusimbisa.
Kugadzirira kwezvinhu
Polypropylene imhando yemhuri ye polyolefin, uye musimboti wayo wekuumba wakavakirwa pakunyunguduka kuyerera kwemapolymer. Iyo huru mbishi zvinhu zvekugadzirirapolypropylene spunbond nonwoven jirai polypropylene particles, kazhinji iine particle size iri pakati pe1-3 millimeters. Mukuwedzera, zvinowedzera zvakadai se cellulose uye girasi fiber zvinoda kuwedzerwa, uye maitiro ekugadzira anokosha anoshandiswa kunyungudutsa zvikamu muine viscous paste.Panguva yekugadzira, kuchenjerera kunofanira kubhadharwa kuchengetedza zvinhu zvakasvibiswa zvakaoma uye kudzivisa kusanganiswa kwetsvina.
Melt spinning
Melt spinning ndeimwe yeakakosha maitiro ekugadzirira polypropylene spunbond nonwoven machira. Isa zvidimbu zvepolypropylene muhopi yekudyisa, zvidyise muchoto chinonyunguduka kuburikidza nescrew conveyor, zvipise kune tembiricha yakakodzera, uye wozopinda muchina wekutenderera. Muchina wekutenderera unoburitsa polypropylene yakanyungudutswa kuita mapores akatsetseka kuti aumbe fiber. Munguva iyi, kutarisisa kunofanirwa kubhadharwa pakugadzirisa maparamendi akadai sekupisa tembiricha, extrusion pressure, uye kutonhora mwero kuti uve nechokwadi chekufanana uye kunaka kwefiber.
Net forming
Mushure mekunyunguduka kutenderera, polypropylene yakagadzira fiber inoenderera, uye inofanirwa kuumba mafibhi kuita mesh. Kugadzira Mesh kunotora nzira yekugadzira pfapfaidzo, apo mafiibha anopfapfaidzwa padhiramu obva abatwa nemaitiro akadai sekudziya, kutonhodza, nekukunguruka kuti apinze mafiibhi uye kugadzira jira risiri rakarukwa sechimiro. Munguva iyi, ma paramita akadai senge nozzle density, adhesive dosage, uye kumhanya kunofanirwa kudzorwa zvine musoro kuti ive nechokwadi chekufanana uye kunaka kwechigadzirwa chakapedzwa.
Shrink velvet
Kudzikira ndiyo nzira yekudzikisa iyorakapera spunbond nonwoven jirakusvika pakukura kwechinangwa. Kune marudzi maviri ekunzwa: dry feeling uye wet feelinging. Dry shrinkage inobatwa nekupisa kwepamusoro uye humidity yakakwirira, nepo shrinkage yakanyorova inoda kuwedzerwa kwemugadziri wemvura panguva yekuderera. Munguva yekuderera kwemaitiro, kutarisisa kunofanirwa kubhadharwa kune kudzora ma parameter senge shrinkage rate, kupisa kupisa nguva, uye tembiricha kuve nechokwadi kugadzikana kweyakapedzwa saizi yechigadzirwa.
Yakagadziriswa chimiro
Kugadzira inzira yekudziisa jira rakapwanyika spunbond risingarukwa kuti rirambe richida chimiro nehukuru hwaro. Iyo yekugadzira maitiro inoitwa uchishandisa inopisa rollers, kuyerera kwemhepo, uye dzimwe nzira, uchiteerera kudzora ma parameter akadai setembiricha, kumhanya, uye kumanikidza kuve nechokwadi kugadzikana kwemhando yekuumbwa.
Maitiro ekugadzira spunbond nonwoven jira rinosanganisira kupisa nekutsikirira uye fusion nemhepo inopisa-yepamusoro-soro mushure mekuumbwa. Muchiitiko ichi, jira risina kuruka rinopinda muimba yemhepo inopisa, uye pasi pekuita kwemhepo inopisa inopisa, mikaha pakati pemafibhi inonyunguduka, zvichiita kuti mafibhi abatane kune mumwe nemumwe, achiwedzera kukurumidza uye kutaridzika kwavo, uye pakupedzisira kugadzira spunbond isina-yakarukwa jira rave rakaumbwa uye rinopisa rakamanikidzwa.
Kupeta mhepo
Maitiro ekumonereka ndeyekukungurutsa jira risiri rakarukwa rine hupamhi hwakati uye hurefu hwekuzotevera kugadzirisa nekufambisa. Muchina wekupetera unowanzo shandisa mvura yekristaro inoratidzira skrini uye programming controller yekushanda, iyo inogona kugadzirisa paramita senge saizi nekumhanya zvinoenderana nezvinodiwa.
Processing
Mucheka weSpunbond usiri wakarukwa ndeye multifunctional composite material inogona kushandiswa kugadzira marudzi akasiyana-siyana emucheka, zvipfeko, masks, filter media, etc. Panguva yekugadzirisa, nzira dzakasiyana-siyana dzokurapa dzakadai sekuchenesa uye kucheneswa, kudhinda uye dhayi, kupfekedza firimu, uye lamination zvinodiwawo kuti uwane kusiyana kwechigadzirwa uye kusiyanisa.
Summary
Iyo nzira yekuyerera kwe polypropylene spunbond nonwoven jira rinonyanya kusanganisira: mbishi kugadzirira, kunyunguduka kutenderera, mesh kuumba, kutema, uye kuumbwa. Pakati pavo, iwo matatu makiyi maitiro ekunyunguduka kutenderera, mesh kuumba, uye kuumbwa kune yakanyanya kukanganisa pane yemuviri uye mechaniki zvimiro zvechigadzirwa chakapedzwa, uye kutonga kwemaitiro avo maparamita kwakakosha. Polypropylene spunbond nonwoven fabric ine zvakanakira uremu huremu, simba repamusoro, uye kufema kwakanaka, uye ine tarisiro yakakura yebudiriro mumashandisirwo emangwana.
Dongguan Liansheng Nonwoven Fabric Co., Ltd., mugadziri wemicheka isina mucheka uye micheka isina kugadzirwa, akakodzera kuvimba kwako!
