Kutaura nezvazvospunbond jira risiri rakarukwa, munhu wose anofanira kuriziva nemhaka yokuti mashandisirwo aro akafara zvikuru zvino, uye rinenge richishandiswa muzvinhu zvakawanda zvoupenyu hwavanhu. Uye zvinhu zvayo zvikuru ipolyester uye polypropylene, saka chinyorwa ichi chine simba rakanaka uye kupisa kwepamusoro. Spunbonded non-woven fabric imhando yejira risiri rakarukwa rinoumbwa nekuburitsa uye kutambanudza mapolymers kuti aite mafilaments anoramba achiiswa, anozoiswa mumambure osungwa kuburikidza neayo ega ekupisa, makemikari, kana mechanical nzira. Iine huwandu hwakawanda hwekushandisa, uye vanhu vanojairana nemabhegi asiri akarukwa, asina-kurukwa packaging, zvichingodaro. Uye zvakare iri nyore kwazvo kuziva, kazhinji ine yakanaka bi-directional kusimba, uye mapoinzi ayo ekutenderera akaumbwa nedhaimani.
Application scope
Chiyero chekushandisa chespunbond jira risiri rakarukwainogona zvakare kushandiswa sechikamu chekurongedza chemaruva nemucheka mutsva wekurongedza, nezvimwe. Uye zvakare inoshandiswa zvakanyanya mumachira ekukohwa ekurima. Anewo huvepo hwake muzvigadzirwa zvekurapa nemaindasitiri zvinoraswa, fenicha, uye zvigadzirwa zvehutsanana mumahotera. Saka. Kutevedzera kunamira jira risiri rakarukwa rine huwandu hwakawanda hwezvikero uye rinogadzirwa pachishandiswa kudhirowa kwakanaka. Nekuda kweiyi nzira, iyo solidification network yakabatana, uye zvigadzirwa zvinogadzirwa nekushandisa feni yekuyamwa zvakakasharara, zvichikonzera kusakwana kwefiber kutambanudza panguva imwe. Izvi zvinodaro nekuda kwechikonzero ichi, hazvigoneke kugadzira zvigadzirwa zviri pamusoro pe120 magiramu pamativi emamita.
Nzira yekugadzira jira risiri rakarukwa
Uye maitiro ekugadzira anogona kuchinjika kugadziridzwa. Bhokisi rinotenderera remutsetse wekugadzira wakabatana uchashandisa akawanda akazvimirira metering pombi kuyera kunyungudika. Uye imwe neimwe metering pombi inopa huwandu hwese kune yakagadziriswa nhamba yezvinotenderera zvikamu. Nekuda kweizvi, pombi yemamita inogona kumiswa zvinoenderana nezvinodiwa nemutengi mukugadzira, uyezve baffle yemuchina wemucheka unogona kugadziridzwa kugadzira zvigadzirwa zvakapedzwa zvehupamhi hwakasiyana. Uye zvakare, kana zvimwe zvinongedzo zvinongedzo zvezvigadzirwa zvehafu-zvakapedzwa zvikasasangana nezviyero, zvinowirirana machira zvinogona kutsiviwa kuti zvigadziriswe.
Chii chinonzi basic process flow ofspunbond nonwoven fabric?
1. Kucheka uye kubika
Iwo machipisi epolymer anowanikwa kuburikidza negranulation uye kukanda mabhandi ekutapurirana anowanzo aine humwe hunyoro hwehunyoro, hunoda kuomeswa nekubviswa usati watenderera.
2. Kutenderera
Midziyo yekutenderera uye tekinoroji inoshandiswa munzira yespunbond yakangofanana neiyo inoshandiswa mumakemikari fiber kuruka. Midziyo mikuru uye zvishongedzo ndeye screw extruders uye spinnerets.
3. Tambanudza
Iwo achangobva kuumbwa melt spun fibers (mafiber ekutanga) ane simba rakaderera, kureba kwakakwirira, chimiro chisina kugadzikana, uye haana mashandiro anodiwa pakugadzira machira, anoda kutambanudza.
4. Filamentation
Iko kunonzi kupatsanurwa kunoreva kupatsanurwa kwemafiibha akatambanudzwa kuita shinda imwe chete kudzivirira mafiibha kubva kunamira kana kupfumvutira panguva yekugadzira webhu.
5. Kuisa mambure
(1) Kudzora kuyerera kwemhepo
(2) Mechanical kudzivirira uye kutonga
(3) Mushure mekutambanudza uye kupatsanurwa, iyo filament inoda kuiswa zvakaenzana pajira remesh.
6. Suction mambure
Nekushandisa mambure ekukweva, kuyerera kwemhepo kunodzika kunogona kutakurwa uye kudzokororwa kwetambo kunogona kudzorwa. Naizvozvo, pane 20 centimita gobvu yakatwasuka air guide orifice plate pasi pemambure keteni kudzivirira kudzoka kwemhepo kubva pakuvhuvhuta pamambure. Peya yemhepo isingapindi mhepo inorongedzerwa pamuganho wekusveta munzira yekumberi kwefiber mesh. Roller yekumusoro ine dhayamita yakakura, yakati chechetere, uye ine banga rekuchenesa kudzivirira kuti roller isabatike. Iyo yepasi roller ine dhayamita diki uye inowanzo sungwa nerubha roller kuita mesh curtain. Iyo yekubatsira yekukweva duct yakananga mumhepo yekumanikidza mambure, nekudaro ichidzora iyo fiber net kuti ibatanidze kune mesh keteni.
7. Kusimbisa
Kusimbisa ndiyo yekupedzisira maitiro, ayo anoita kuti mesh ive neimwe simba, kurebesa, uye zvimwe zvivakwa kuti zvisangane nechigadzirwa chinodiwa.
Kana kufema kwakashata, boka rinotenderera rine maburi mashoma pane spinneret rinogona kutsiviwa, izvo zvinogona kuwedzera kufema kwejira rejira. Iye zvino, kudzvinyirirwa kwemhepo yeimwe-nzira inotungamira cylinder inogonawo kugadziriswa kuti iite zvinhu zvemuviri zvehupamhi hwese yunifomu. Simba reparutivi rejira re spunbond risiri rakarukwa rakati wedzerei, uye nzira yekuruka inoshandisa machira kugadzira dandemutande. Iyo shiti inoramba ichitenderera ichienda kumashure ne750Hz, uye iyo yakakwirira-inomhanya yakatambanudzwa fiber inorovera padivi nemambure.
Simba respunbond jirayakakwira zvakanyanya nekuti mesh keteni inoenda mberi diagonally uye interlaces. Kusimba uye kuchinjika kwemanotsi kunogona kusvika pa1: 1. Kazhinji kutaura, kuenzanisa kunoshandisa Venturi riser, asi simba rayo harina kunyanya kukwirira, uye iyo longitudinal uye inochinjika simba yakasimba zvakanyanya. Mafiber emachira asina kuruka pawebhusaiti ane yakanaka-yepamusoro-tembiricha kuramba uye kupfeka kuramba, uye simba ravo remuchina rakakura kupfuura iro rePP fibers.
Chii chinofanira kutariswa panguva yekukunguruka kwejira risiri rakarukwa re spunbond?
1. Munguva yekugadzira mhepo, tenzi kudzora kwekumanikidza kwe spunbond jira risiri rakarukwa.
2. Kana kukakavara kunowedzera mukati meimwe mhando, dhayamita uye upamhi hwespunbond nonwoven rollkupera.
3. Kana kukakavara kunowedzera mukati meimwe nzvimbo, inogona kuwedzerwa. Izvo zvinodikanwa chaizvo zvemakakatanwa ari pamusoro zvinofanirwa kupfupikiswa mukugadzirwa chaiko kuve nechokwadi chemhando.
4. Panguva yekugadzira, teerera kuti ugare uchitarisa upamhi uye mupumburu kureba kwespunbond isiri-yakarukwa jira.
5. Iyo pepa chubhu uye spunbond isiri-yakarukwa yejira roll inofanirwa kuenderana.
6. Chenjerera kuongororwa kwekutaridzika kwemhando ye spunbond isiri-yakarukwa jira, sekudonha, kuputika, kubvarura, nezvimwe.
7. Rongedza zvinoenderana nezvinodiwa zvekugadzira, teerera kune utsanana, uye ona kuti kurongedza kwakasimba.
8. Sampling uye kuyedzwa kwebatch yega yega yespunbond isiri-yakarukwa jira.
