Indwangu engalukiwe ye-Polypropylene spunbond iwuhlobo olusha lwempahla eyenziwe nge-polypropylene encibilikisiwe ngezinqubo ezinjengokuphotha, ukwakheka kwemeshi, ukusika, nokubumba. Indwangu ye-polypropylene spunbond nonwoven inezakhiwo ezinhle kakhulu zomzimba nezomshini, futhi isetshenziswa kabanzi emikhakheni efana neyokwakha, ukunakekelwa kwezempilo, inhlanzeko, impahla yasendlini, kanye nezimoto.
Ukugeleza kwenqubo yokwenza izindwangu ezingalukiwe kusuka ku-polypropylene: ukondla kwe-polymer - i-melt extrusion - ukwakheka kwe-fiber - ukupholisa i-fiber - ukwakheka kwewebhu - ukuqinisa kube yindwangu.
Ukwethulwa okuningiliziwe kokugeleza kwenqubo yokukhiqiza izindwangu ezingalukiwe kusuka ku-polypropylene:
Hlanganisa i-polypropylene nezithasiselo ngokulinganayo ku-mixer, bese wengeza ingxube ewumphumela ku-feeder ku-extruder (njenge-twin-screw extruder). Impahla ingena ku-twin-screw ngokusebenzisa i-feeder, iyancibilika futhi ixutshwe ngokulinganayo ngesikulufu, ikhishwe, icwecwe, futhi yomiswe ukuze kutholwe amapellets wempahla eluhlaza engalukiwe; Khona-ke, ama-pellets wendwangu engalukiwe engalukiwe engezwa kusikulufa esisodwa sokuncibilika nokuxutshwa, ukukhishwa, ukwelula ukugeleza komoya, ukupholisa nokuqiniswa, ukufakwa kwe-mesh, nokuqinisa.
Ukulungiselela impahla eluhlaza
I-Polypropylene wuhlobo lomndeni we-polyolefin, futhi umgomo wayo wokubumba usekelwe ekuncibilikeni kokuncibilika kwama-polymers. The main impahla eluhlaza ukulungiselelai-polypropylene spunbond indwangu engalukiweizinhlayiya ze-polypropylene, ngokuvamile ezinosayizi wezinhlayiyana phakathi kwamamilimitha angu-1-3. Ngaphezu kwalokho, izithasiselo ezifana ne-cellulose ne-glass fiber zidinga ukungezwa, futhi izinqubo zokukhiqiza ezikhethekile zisetshenziselwa ukuncibilikisa izinhlayiya zibe yi-viscous paste.Ngesikhathi sokukhiqiza, ukunakekelwa kufanele kukhokhwe ekugcineni izinto eziluhlaza zomile futhi zigweme ukuxuba ukungcola.
Melt ukuphotha
I-Melt spinning ingenye yezinqubo eziyinhloko zokulungiselela izindwangu ezingalukiwe ze-polypropylene spunbond. Beka izinhlayiya ze-polypropylene ku-hopper yokudla, uzifake esithandweni esincibilikayo ngokusebenzisa isidlulisi se-screw, uzishise ezingeni lokushisa elifanele, bese ufaka umshini wokuphotha. Umshini wokuphotha ukhipha i-polypropylene encibilikisiwe ibe yizimbotshana ezinhle ukuze yenze imicu. Phakathi nale nqubo, ukunakwa kufanele kukhokhwe ekulungiseni imingcele efana nezinga lokushisa lokushisa, ingcindezi ye-extrusion, nezinga lokupholisa ukuze kuqinisekiswe ukufana nokucoleka kwemicu.
Ukwakhiwa kwenetha
Ngemuva kokuncibilika kokuphotha, i-polypropylene yenze imicu eqhubekayo, futhi kuyadingeka ukubumba imicu ibe yimeshi. Ukwakhiwa kwemeshi kusebenzisa indlela yokwenza isifutho, lapho imicu ifuthwa esigubhini bese iphathwa ngezinqubo ezifana nokushisisa, ukupholisa, nokugingqika ukuze kweluke imicu futhi kwakhiwe indwangu engalukiwe njengesakhiwo. Phakathi nale nqubo, amapharamitha afana nokuminyana kwe-nozzle, umthamo wokunamathela, nesivinini kufanele kulawulwe ngokunengqondo ukuze kuqinisekiswe ukufana kanye nekhwalithi yomkhiqizo oqediwe.
Nciphisa i-velvet
Ukuncipha kuyinqubo yokunciphisa i-i-spunbond iqedile indwangu engalukiwekusayizi oqondiwe. Kunezinhlobo ezimbili zokufenda: ukusika okomile kanye nokuzwa okumanzi. I-shrinkage eyomile iphathwa ngokushisa okuphezulu kanye nomswakama ophezulu, kuyilapho ukuncipha okumanzi kudinga ukungezwa kwe-ejenti yokumanzisa ngesikhathi senqubo yokuncipha. Phakathi nenqubo yokuncipha, ukunakwa kufanele kukhokhwe ekulawuleni imingcele efana nesilinganiso sokuncipha, isikhathi sokwelashwa kokushisa, kanye nezinga lokushisa ukuze kuqinisekiswe ukuzinza kosayizi womkhiqizo oqediwe.
Umumo olungisiwe
Ukwakhiwa kuyinqubo yokushisisa indwangu engalukiwe eshwabene ye-spunbond ukuze igcine umumo nosayizi oyifunayo. Inqubo yokubumba yenziwa kusetshenziswa ama-roller ashisayo, ukugeleza komoya, nezinye izindlela, kuyilapho inaka imingcele yokulawula efana nezinga lokushisa, isivinini, nokucindezela ukuze kuqinisekiswe izinga elizinzile lokubunjwa.
Inqubo yokubumba yendwangu engalukiwe ye-spunbond ihlanganisa ukucindezela okushisayo nokuhlanganiswa komoya oshisayo onezinga eliphezulu lokushisa ngemva kokubunjwa. Kule nqubo, indwangu engalukiwe ingena ekamelweni lomoya oshisayo, futhi ngaphansi kwesenzo somoya oshisayo wesivinini esikhulu, izikhala phakathi kwemicu ziyancibilika, okubangela ukuthi imicu ihlangane komunye nomunye, ikhulise ukushesha nokubukeka kwayo, futhi ekugcineni yakha indwangu engalukiwe ye-spunbond eye yabunjwa futhi yacindezelwa.
Iyaphela
Inqubo yokusonta iwukugingqa indwangu engalukiwe enobubanzi obuthile nobude ukuze kucutshungulwe futhi kuthuthwe. Umshini onamawindi ngokuvamile usebenzisa isikrini sokubonisa ikristalu eliwuketshezi kanye nesilawuli sokuhlela ukuze sisebenze, esingalungisa amapharamitha afana nosayizi nesivinini ngokuya ngezidingo.
Iyacubungula
Indwangu engalukiwe ye-Spunbond iyinhlanganisela yezinto eziningi ezingasetshenziswa ukwenza izinhlobo ezahlukene zezindwangu, izingubo zokugqoka, imaski, imidiya yokuhlunga, njll. Ngesikhathi sokucubungula, izindlela ezihlukahlukene zokwelapha ezifana nokuhlanza nokuhlanza, ukuphrinta nokudaya, ukumboza ifilimu, kanye ne-lamination nazo ziyadingeka ukuze kuzuzwe ukuhlukahluka komkhiqizo nokuhlukaniswa.
Isifinyezo
Inqubo yokugeleza kwendwangu ye-polypropylene spunbond engalukiwe ihlanganisa ikakhulukazi: ukulungiswa kwempahla eluhlaza, ukuphotha okuncibilikayo, ukwakheka kwemeshi, ukusika, nokubumba. Phakathi kwazo, izinqubo ezintathu ezibalulekile zokuphotha okuncibilikayo, ukwakheka kwe-mesh, kanye nokubunjwa kunomthelela omkhulu ezimpahleni ezingokomzimba nezomshini zomkhiqizo oqediwe, futhi ukulawulwa kwemingcele yenqubo yabo kubalulekile. Indwangu engalukiwe ye-polypropylene spunbond inezinzuzo zesisindo esilula, amandla aphezulu, nokuphefumula okuhle, futhi inamathemba okuthuthuka okubanzi ekusetshenzisweni okuzayo.
I-Dongguan Liansheng Nonwoven Fabric Co., Ltd., umkhiqizi wezindwangu ezingezona eziboshwe kanye nezindwangu ezingezona ezilukiwe, ufanelwe ukwethenjwa kwakho!
