Enqubweni yokukhiqiza yama-nonwovens a-spunbonded, izici ezihlukahlukene zingathinta izakhiwo ezibonakalayo zemikhiqizo.
Ukuhlaziywa kwezinto eziyinhloko ezithinta izakhiwo zendwangu kuyasiza ukulawula izimo zenqubo ngendlela efanele futhi uthole ama-nonwovens amahle e-PP anekhwalithi enhle ukuze alingane nokusebenza kwamakhasimende.
Uhlobo lwe-1.Polypropylene: inkomba encibilikayo nesisindo samangqamuzana
Izinkomba eziyinhloko zekhwalithi yezinto ze-polypropylene ziyisisindo samangqamuzana, ukusatshalaliswa kwesisindo samangqamuzana, i-isotacticity, inkomba yokuncibilika kanye nokuqukethwe komlotha.
Abahlinzeki be-polypropylene basenhla neketango lepulasitiki, bahlinzeka ngezinto ezingasetshenzisiwe ze-polypropylene kumabanga ahlukahlukene kanye nokucaciswa.
Ukwenza i-spunbond ingabi nowoven, isisindo semolekyuli ye-polypropylene ngokuvamile sisuka ku-100,000-250,000.Kodwa-ke, kufakazelwe ukuthi i-melt property isebenza kahle kakhulu lapho isisindo semolekyuli singaba ngu-120000. Isivinini sokuphotha esiphezulu siphezulu kuleli zinga.
Inkomba ye-Melt iyipharamitha ekhombisa izakhiwo ze-rheological zokuncibilika.Inkomba yokuncibilika yezinhlayiyana ze-PP ze-spunbond ngokuvamile iphakathi kuka-10 no-50.
Inkomba encane yokuncibilika iwukuthi, i-fluidity iba yimbi kakhulu, isilinganiso sokubhala sincane, futhi ubukhulu be-fiber bukhulu obungaphansi kwesimo sokuphuma okufanayo kwe-ncibilika kusuka ku-spinneret, ngakho-ke ama-nonwovens abonisa imizwa yesandla esiqinile.
Lapho inkomba yokuncibilika ikhudlwana, i-viscosity yokuncibilika iyancipha, impahla ye-rheological iza kangcono, futhi ukumelana nokubhala kuncipha.Ngaphansi kwesimo esifanayo sokusebenza, ukuhlelwa okuningi kuyakhuphuka.Ngokukhula kwe-orientation degree yama-macromolecules, amandla okuphuka e-nonwoven azothuthukiswa, futhi usayizi wentambo uzoncishiswa, futhi indwangu izozizwa ithambile.Ngenqubo efanayo, ukuphakama kwenkomba yokuncibilika, amandla okuphuka enza kahle kakhulu. .
2. Izinga lokushisa lokuphotha
Ukusethwa kwezinga lokushisa lokuphotha kuncike kunkomba yokuncibilika kwezinto ezingavuthiwe kanye nezidingo zezakhiwo ezibonakalayo zemikhiqizo.Ukuphakama kwenkomba yokuncibilika kudinga izinga lokushisa eliphezulu lokuphotha, futhi ngokuphambene nalokho.Izinga lokushisa lokuphotha lihlobene ngokuqondile ne-viscosity encibilikayo.Ngenxa ye-viscosity ephezulu yokuncibilika, kunzima ukuphotha, okuholela ekuqhekekeni, okuqinile noma okuqinile kwentambo, okuthinta ikhwalithi yemikhiqizo.
Ngakho-ke, ukuze unciphise i-viscosity yokuncibilika futhi uthuthukise izakhiwo ze-rheological zokuncibilika, ukwandisa izinga lokushisa ngokuvamile kwamukelwa.Izinga lokushisa elijikelezayo linethonya elikhulu esakhiweni nasezindaweni zemicu.
Uma izinga lokushisa lokuphotha seliphakeme, amandla okuphuka angaphezulu, ubude obuphukayo buba buncane, futhi indwangu izwakala ithambe kakhulu.
Ngokusebenza, izinga lokushisa lokuphotha livame ukusetha i-220-230 ℃.
3. Izinga lokupholisa
Enqubweni yokwakhiwa kwama-nonwovens asontiwe, izinga lokupholisa lentambo linethonya elikhulu ezimpahleni ezibonakalayo zama-nonwovens aphothiwe.
Uma i-fiber ipholile kancane, ithola isakhiwo sekristalu esizinzile se-monoclinic, esingenakukwazi ukudonsa imicu.Ngakho-ke, enqubweni yokubumba, indlela yokwandisa ivolumu yomoya opholile kanye nokunciphisa izinga lokushisa kwekamelo lokuphotha ngokuvamile isetshenziselwa ukuthuthukisa amandla okuphuka futhi unciphise ukunwebeka kwendwangu engalukiwe ephothiwe.Ngaphezu kwalokho, ibanga lokupholisa lentambo nalo lihlobene eduze nezakhiwo zalo.Ekukhiqizeni izindwangu ezingalukiwe eziphothiwe, ibanga lokupholisa ngokuvamile liphakathi kuka-50 cm no-60 cm.
4. Izimo Zokubhala
I-orientation degree ye-molecular chain in filament iyisici esibalulekile esithinta ukwehlukana kwe-monofilament.
Ukufana namandla okuphuka kwama-nonwovens asontekile angathuthukiswa ngokwandisa umthamo womoya wokumunca.Kodwa-ke, uma umthamo womoya wokudonsa mkhulu kakhulu, kulula ukugqabula intambo, futhi okusalungiswa kunzima kakhulu, ukuqondiswa kwe-polymer kuvame ukuphelela, futhi ubucwebe be-polymer buphakeme kakhulu, okuzonciphisa umthelela amandla kanye nobude ngesikhathi sekhefu, futhi andise ukushwabana, okuholela ekwehleni kwamandla kanye nobude bendwangu engalukiwe.Kuyabonakala ukuthi amandla kanye nokwelulwa kwama-nonwovens ayi-spunbonded akhuphuka futhi ehle njalo ngokukhuphuka kwevolumu yomoya wokudonsa.Ekukhiqizeni kwangempela, inqubo kufanele ilungiswe ngokuvumelana nezidingo kanye nesimo sangempela ukuze kutholwe imikhiqizo yekhwalithi ephezulu.
5. Izinga lokushisa elishisayo
Ngemuva kokwakhiwa kwewebhu ngomdwebo, iyaxega futhi kufanele iboshwe ngokugoqa okushisayo.Okubalulekile wukulawula izinga lokushisa nomfutho.Umsebenzi wokushisa uwukuthambisa nokuncibilikisa i-fiber.Ingxenye yemicu ethambile futhi ehlanganisiwe inquma izici ezibonakalayo zendwangu engalukiwe ye-PP spunbond.
Lapho izinga lokushisa liqala liphansi kakhulu, ingxenye encane kuphela yemicu encane enesisindo esiphansi samangqamuzana iyathamba futhi inyibilike, imicu embalwa iboshelwa ndawonye ngaphansi kwengcindezi.Imicu ekuwebhu kulula ukushelela, amandla okuphuka kwendwangu engalukiwe mancane futhi ubude bukhulu, futhi indwangu izwakala ithambile kodwa kungenzeka ukuthi ibe yi-fuzz;
Lapho izinga lokushisa elishisayo likhuphuka, inani le-fiber ethambile futhi encibilikile liyakhula, i-fiber web iboshelwa eduze, akulula ukushelela.Amandla okuphuka kwendwangu engalukiwe ayanda, futhi ukunwetshwa kusekukhulu.Ngaphezu kwalokho, ngenxa yokuhlobana okuqinile phakathi kwemicu, ukunwetshwa kuyanda kancane;
Lapho izinga lokushisa likhuphuka kakhulu, amandla ama-nonwovens aqala ukwehla, ubude buyancipha kakhulu, uzwa indwangu iba nzima futhi ishwabene, namandla okudabula ayancipha.Ezintweni eziwugqinsi oluphansi, kunemicu emincane endaweni eshisayo futhi iyancipha. ukushisa okudingekayo ukuze kuthambise futhi kuncibilike, ngakho-ke izinga lokushisa elishisayo kufanele lehle.Ngokuhambisanayo, ezintweni eziwugqinsi, izinga lokushisa elishisayo liphezulu.
6. I-Hot rolling pressure
Enqubweni yokuhlanganisa yokuginqika okushisayo, umsebenzi wokucindezela komugqa wokugaya oshisayo uwukwenza imicu ethambile futhi encibilikisiwe ihlangane eduze, ikhulise ukuhlangana phakathi kwemicu, futhi yenze imicu ingabi lula ukushelela.
Uma ingcindezi yolayini ogoqelwe oshisayo iphansi ngokuqhathaniswa, ukuminyana kwefayibha endaweni yokucindezela kubi, ukushesha kwe-fiber bonding akuphezulu, futhi ukuhlangana phakathi kwemicu kuba kubi.Ngalesi sikhathi, umuzwa wesandla wendwangu engalukiwe ephothiwe uthambile uma kuqhathaniswa, ubude ngesikhathi sekhefu bukhulu kakhulu, kodwa amandla okuphuka aphansi;
ngokuphambene, lapho ingcindezi yomugqa iphakeme ngokuqhathaniswa, umuzwa wesandla wendwangu engalukiwe ephothiweyo unzima uma kuqhathaniswa, futhi ubude ngesikhathi sekhefu buphansi ngokuqhathaniswa Kodwa amandla okuphuka aphakeme.Ukumiswa kokucindezela okushisayo okugoqayo kuhlobene kakhulu nesisindo nokuqina kwezindwangu ezingalukiwe.Ukuze ukhiqize imikhiqizo ehlangabezana nezidingo zokusebenza, kuyadingeka ukukhetha ukucindezela okushisayo okushisayo okufanelekile ngokuya ngezidingo.
Ngamafuphi nje, izici ezibonakalayo zezindwangu ezingezona ezilukiwe ziwumphumela wokusebenzelana kwezinto eziningi.Ngisho nogqinsi olufanayo lwendwangu, ukusetshenziswa kwendwangu okuhlukile kungase kudinge inqubo yobuchwepheshe ehlukahlukene.Yingakho ukucasuka kwekhasimende kubuzwe ukusetshenziswa kwendwangu.Kuzosiza umhlinzeki. hlela ukukhiqizwa ngenjongo ethile futhi unikeze ikhasimende elithandekayo indwangu engalukiwe eyaneliswe kakhulu.
Njengomkhiqizi weminyaka eyi-17, iFuzhou Heng Hua New Material Co., Ltd.bayazethemba bahlinzeke ngendwangu ngokwesidingo samakhasimende.Besithumela emazweni ahlukahlukene nasezifundeni futhi siye sanconywa kakhulu ngabasebenzisi.
Siyakwamukela uxhumane nathi futhi uqale ukubambisana kwesikhathi eside ne-Henghua Nonwoven!
