Phakathi nenqubo yokukhiqizai-polyester spunbond indwangu engalukiwe, izinkinga zekhwalithi yokubukeka zivame ukwenzeka. Uma kuqhathaniswa ne-polypropylene, ukukhiqizwa kwe-polyester kunezici zokushisa kwenqubo ephezulu, izidingo zokuqukethwe komswakama ophezulu wezinto ezingavuthiwe, izidingo zejubane eliphezulu lokudweba, kanye nogesi ophezulu omile. Ngakho-ke, ubunzima bokukhiqiza buphakeme kakhulu, futhi amathuba okuba nezinkinga zekhwalithi yokubukeka aphezulu. Ezimweni ezimbi kakhulu, kungase kuthinte ukusetshenziswa kwamakhasimende. Ngakho-ke, ukuhlukanisa ngokuphumelelayo izinkinga zekhwalithi zokubukeka ezikhona ohlelweni lokukhiqiza, ukuhlaziya izimbangela eziyinhloko zezinkinga ezihlukahlukene, nokuthatha izinyathelo eziphumelelayo zokuvimbela nokugwema izinkinga zekhwalithi ezivamile yimisebenzi eyinhloko ekulawuleni inqubo yokukhiqiza i-polyester spunbond.
Uhlolojikelele Lwezindaba Zekhwalithi Yokubukeka kweIndwangu yePolyester Spunbond Eshisayo Egingqiwe Engalukiwe
Kunezinkinga ezahlukahlukene zekhwalithi yokubukeka ngezindwangu ezingalukiwe ze-polyester spunbond ezigoqiwe ezishisayo. Ngokusekelwe eminyakeni yokuhlangenwe nakho, ingahlukaniswa ngokuyinhloko izigaba ezintathu, kanje: isigaba sokuqala izinkinga zekhwalithi ezibangelwa izici zokuphotha, njengezigaxa ze-pulp, imicu eqinile, izigaxa eziqinile, ukunwebeka okwanele, amaphuzu okugoqa angacacile, njll. Isigaba sesibili izinkinga zekhwalithi zokubukeka ezibangelwa izici zokubeka i-mesh, njengokupheqa, ukubhoboza, imivimbo emincane eqhubekayo, imicu emincane evundlile, i-diagonal evundlile. njll; Uhlobo lwesithathu izinkinga zekhwalithi ezibangelwa izici zemvelo, njengamabala amnyama, omiyane, imivimbo emikhulu evundlile, njll. Lesi sihloko sihlaziya izimbangela zalezi zinhlobo ezintathu zezinkinga futhi siphakamisa izinyathelo ezihambisanayo zokuvimbela kanye nezixazululo.
Izinkinga zekhwalithi yokubukeka nezizathu ezibangelwa izici zokuphotha
Amabhulokhi ane-slurry nemicu eqinile
Kunezizathu eziningi zokwakheka kwezigaxa kanye nemicu eqinile, eye yethulwa ezintweni eziningi zezincwadi. Lesi sihloko sihlaziya kuphela izizathu eziyinhloko zokwakheka kwezigaxa kanye nemicu eqinile phakathi nezinqubo zokukhiqiza ezivamile: (1) ukuvuza kwengxenye; (2) Ukusetshenziswa ngokweqile noma ukusebenza okungalungile kwe-spinneret kungabangela umonakalo kuma-micropores noma izinto zangaphandle, okuholela ekuphumeni okubi kwentambo; (3) Ukusika omisiwe noma ukwengeza i-masterbatch enamanzi amaningi kakhulu; (4) Ingxenye ye-masterbatch esebenzayo eyengezwe iphezulu kakhulu: (5) izinga lokushisa lokushisa endaweni yasendaweni ye-screw extruder liphezulu kakhulu; (6) Isikhathi sokukhipha esinganele ngesikhathi sokuqalisa nokuvala, okuholela ekuncibilikeni okusele okucekeleke phansi; (7) Isivinini somoya ovunguzayo ohlangothini siphansi kakhulu, okwenza imicu inyakaze kakhulu ngenxa yokuphazamiseka kokugeleza komoya kwangaphandle, noma isivinini somoya esiphephuka eceleni siphezulu kakhulu, okwenza imicu inyakaze kakhulu.
Izinyathelo zokuvimbela: (1) Uma uqala futhi umisa umugqa wokukhiqiza, kuyadingeka ukuqinisekisa isikhathi esanele sokukhululwa, zama ukukhipha ukuncibilika ngokuphelele, futhi usebenzise uhlelo lokugeza olushisayo lwe-polypropylene index ephansi njalo; (2) Nakisisa izinqubo zokuhlanza nokuhlanganisa izingxenye ukuze uqinisekise ubuqotho bazo emshinini.
