Yiziphi izizathu zokusetshenziswa kakhulu kwe-polypropylene kubuchwepheshe obuncibilikisiwe?

Umgomo wokukhiqiza wendwangu encibilikisiwe

Indwangu ye-Meltblown iyimpahla encibilikisa ama-polymers emazingeni okushisa aphezulu bese iwafafaza ibe imicu ngaphansi kwengcindezi ephezulu. Le micu ipholisa ngokushesha futhi iqine emoyeni, yakhe inethiwekhi yefayibha enokuminyana okuphezulu, esebenza kahle kakhulu. Lezi zinto azigcini nje ngokusebenza kahle kokuhlunga, kodwa futhi azisindi futhi ziyaphefumula, okwenza zifaneleke kakhulu ukusetshenziswa emishinini yokuzivikela njengamamaski.

Izinto zokusetshenziswa main for izindwangu meltblown

Impahla eluhlaza eyinhloko yendwangu encibilikisiwe yi-polypropylene, eyaziwa ngokuthi yi-PP material. Njengamanje, imaski evamile yendwangu encibilikisiwe emakethe isebenzisa indwangu encibilikisiwe ye-polypropylene njengento yokuhlunga. Isizathu sokukhetha i-polypropylene njengento eyinhloko eluhlaza ukuthi inokusebenza okuhle kokucubungula kanye nezinzuzo zezindleko, futhi ihambisana nemvelo.

Ngaphandle kwe-polypropylene, izindwangu ezincibilikisiwe nazo zingenziwa ngezinye izinto ezifana ne-polyester, inayiloni, ilineni, njll Kodwa-ke, uma kuqhathaniswa ne-polypropylene, lezi zinto zinezindleko eziphakeme noma ukucubungula ukucubungula okumpofu, okwenza zingafanelekile ukukhiqizwa okukhulu.

I-Polypropylene isetshenziswa kakhulu kubuchwepheshe obuncibilikisiwe ngenxa yokuthi inezinzuzo ezilandelayo

1. I-viscosity ye-polymer ingalawulwa ngokusebenzisa ama-oxidants noma ama-peroxides enqubweni ye-extrusion, noma ngokugunda i-extruder ngomshini noma ukulawula izinga lokushisa elisebenzayo ukuze kuzuzwe ukuwohloka kokushisa, ukuze kulawulwe i-viscosity yokuncibilika.

2. Ukusatshalaliswa kwesisindo samangqamuzana kungalawulwa inqubo yendwangu engalukiwe encibilikisiwe, edinga ukusatshalaliswa kwesisindo samangqamuzana emincane ukuze kukhiqizwe imicu ye-ultrafine efanayo. Ngokusebenzisa ubuchwepheshe obusha be-catalytic obufana nama-metallocene catalysts, ama-polymer anenkomba ephezulu kakhulu yokuncibilika kanye nokusabalalisa kwesisindo samangqamuzana amancane angakhiqizwa.

3. Iphuzu eliphakeme lokuncibilika lanele ukumelana nokushisa kwe-polypropylene ezinhlelweni eziningi zomkhiqizo, futhi inohlu olubanzi lwe-propylene encibilikisiwe. Ngakho-ke, ububanzi buzuzisa kakhulu ukucutshungulwa kokubopha okushisayo okuvame ukusetshenziswa kubuchwepheshe bendwangu engalukiwe.

4. Kuyazuzisa ukukhiqiza imicu ye-ultrafine. Uma i-viscosity ye-polypropylene melt iphansi futhi ukusatshalaliswa kwesisindo samangqamuzana kuncane, kungenziwa kube imicu emihle kakhulu ngaphansi kokusetshenziswa kwamandla okufanayo kanye nezimo ezinwebekayo enqubweni yokuncibilika. Ngakho-ke, ububanzi befayibha evamile ye-polypropylene encibilikayo ephephethwa ngendwangu engalukiwe ingu-2-5um, noma icoleke nakakhulu.

5. Ngenxa yokusetshenziswa komdwebo womoya oshisayo ocindezelwe kakhulu ohlelweni lokufafaza okuncibilikayo, kuyadingeka ukusebenzisa ama-polymers anenkomba ephezulu yokuncibilika, okuzuzisa ukukhulisa ukukhiqiza nokunciphisa ukusetshenziswa kwamandla. Njengamanje, ama-chips e-polypropylene asetshenziswa kakhulu anenkomba yokuncibilika engu-400-1200g/10min kanye nokusabalalisa kwesisindo samangqamuzana amancane ukuze kukhiqizwe imicu ye-ultrafine enomugqa odingekayo wokuminyana.

6. Ama-chip e-polypropylene asetshenziswa ekukhiqizeni nasekucutshungulweni okuncibilikisiwe kufanele abe nenkomba yokuncibilika ephezulu futhi efanayo, ukusatshalaliswa kwesisindo samangqamuzana amancane, izici ezinhle zokucubungula ezincibilikayo ezincibilikayo, kanye nekhwalithi ye-chip efanayo kanye nezinzile ukuze kuqinisekiswe ukuzinza kwenqubo yezinto ezincibilikayo ezingalukiwe.

Izinyathelo zokuqapha ukukhiqizwa kwendwangu encibilikisiwe

Lapho kwenziwa indwangu encibilikisiwe, amaphuzu alandelayo kufanele aqashelwe:

1. Ukukhethwa kwezinto ezibonakalayo kufanele kuhlanzeke ngokwanele: Njengoba indwangu encibilikisiwe idinga ukuthwala umphumela wokuhlunga, kuyadingeka ukukhetha izinto ezihlanzeke ngokwanele lapho kukhethwa izinto zokusetshenziswa. Uma kukhona ukungcola okuningi kakhulu, kuzothinta ukusebenza kahle kokuhlunga kwendwangu encibilikayo.

2. Lawula izinga lokushisa lokucubungula nokucindezela: Izinga lokushisa lokucubungula nokucindezela kufanele kusethwe ngokohlobo lwempahla eluhlaza ukuze kuqinisekiswe ukusebenza kahle kokwakhiwa kwe-fiber.

3. Ukuqinisekisa ukuhlanzeka endaweni yokukhiqiza: Njengoba indwangu encibilikisiwe isetshenziselwa ukukhiqiza izinto zokuzivikela ezifana nemaski, inhlanzeko endaweni yokukhiqiza ibaluleke kakhulu. Kuyadingeka ukuqinisekisa ukuhlanzeka kwendawo yokusebenzela yokukhiqiza ukugwema ukungcolisa imikhiqizo.

I-Dongguan Liansheng Non woven Technology Co., Ltd.yasungulwa ngoMeyi 2020. Kuyibhizinisi elikhulu lokukhiqiza indwangu engalukiwe ehlanganisa ucwaningo nentuthuko, ukukhiqiza, nokudayiswa. Ingakwazi ukukhiqiza imibala ehlukahlukene ye-PP spunbond izindwangu ezingalukiwe ezinobubanzi obungaphansi kwamamitha angu-3.2 ukusuka ku-9 amagremu kuya ku-300 amagremu.
