Izindlela zokuthuthukisa ikhono eliphezulu le-polypropylene

Ngokusetshenziswa okwandayo kwepolypropylene izintoemikhakheni ehlukahlukene, izidingo zekhono labo elingaphezulu nazo ziya ngokuya ziba phezulu. Kodwa-ke, ikhono eliphansi le-polypropylene ngokwayo libeka imikhawulo ethile ekusetshenzisweni kwayo. Ngakho-ke, indlela yokuthuthukisa ikhono eliphezulu le-polypropylene isiphenduke indawo yocwaningo.

Izindlela eziningana zokuthuthukisa ikhono eliphezulu le-polypropylene

Khulisa ubulukhuni bobuso

Ngokwandisa ubulukhuni bendawo ye-polypropylene, ikhono layo elingaphezulu lingathuthukiswa. Isibonelo, ukwelashwa kwe-sandblasting noma ukudweba kungasetshenziswa ebusweni be-polypropylene ukuze kwandiswe isakhiwo sayo sejometri futhi ngaleyo ndlela kuthuthukise amandla ayo angaphezulu. Phakathi naleso sikhathi, ubulukhuni obungaphezulu bungabuye bukhuliswe ngezindlela ezinjengokucubungula i-electron beam kanye nokufakwa kwe-ion.

Ukulungiswa kobuso

Ukuguqulwa kobuso kuyindlela evamile yokuthuthukisa ikhono elingaphezulu le-polypropylene. Isibonelo, ngokumboza ungqimba lwe-modifier ebusweni be-polypropylene, ikhono layo elingaphezulu lingakhuphuka. Izilungisi ezijwayelekile zifaka ama-siloxanes, ama-polyamides, njll. Lezi zilungisi zingakha isibopho samakhemikhali esiqinile uma kuqhathaniswa ne-polypropylene, ngaleyo ndlela ithuthukise ikhono layo elingaphezulu.

Ukuguqulwa kwamakhemikhali

Ukuguqulwa kwamakhemikhali kuyindlela eqondile yokuthuthukisa ikhono elingaphezulu le-polypropylene. I-Polypropylene ingenziwa i-copolymerized noma ixhunywe nezinye izinto ukuze iguqule izakhiwo zayo ezingaphezulu. Isibonelo, i-polypropylene ingenziwa i-copolymerized noma ixhunywe ne-acrylic acid, i-co methylacrylic acid, njll.

Yiziphi iziqondiso zokulungisa ezingasetshenziswa ukwandisa ukusebenza?

I-Polypropylene, efushanisiwe njenge-PP, ingenye yepulasitiki emihlanu yendawo yonke esetshenziswa kakhulu emikhiqizweni yansuku zonke neyezimboni. Ukuguqulwa kwe-PP kuyinkambu ebanzi ebandakanya izikhombisi-ndlela nezindlela eziningi ezahlukene. Inhloso, ingxenye enkulu, ukunxephezela ukushiyeka kwe-PP ngokwayo nokwandisa izinkambu zayo zokusebenza. Okulandelayo yizinkomba ezijwayelekile zokuguqulwa kwe-polypropylene:

1. Ukulungiswa okuthuthukisiwe:PP impahlaithambile futhi ayinakho ukusekelwa okwanele. Izakhiwo zemishini ye-polypropylene, njengamandla, ukuqina, nokumelana nokugqokwa, zingathuthukiswa ngokungeza i-glass fiber, i-carbon fiber, nanomaterials, njll.

2. Ukugcwalisa ukuguqulwa: I-PP inezinga eliphezulu lokuncipha futhi ijwayele ukuguqulwa ngemva kokubunjwa komjovo. Ngokungeza izihlungi ezifana nezimpushana ze-inorganic kanye nobuhlalu bengilazi encane, izici ze-polypropylene zingathuthukiswa, njengokwandisa ukuhanjiswa kwe-thermal, ukunciphisa izindleko, nokuthuthukisa ukuzinza kwe-dimensional.

3. Ukuguqulwa kokuhlanganiswa: Ukuxuba i-polypropylene namanye ama-polymers noma izithasiselo ukuze kuthuthukiswe izakhiwo zayo, njengokukhula kokuqina, ukumelana namakhemikhali, ukumelana nezinga lokushisa, njll.

4. Izithasiselo ezisebenzayo: I-PP ayinakho ukuncipha komlilo futhi inokumelana nesimo sezulu esibi. Ukwengeza izithasiselo ezinemisebenzi ethile, njengama-antioxidant, ama-UV absorbers, ama-flame retardants, njll., kungathuthukisa ukumelana nesimo sezulu kanye nokumelana nomlilo kwe-polypropylene.

Isiphetho

Sekukonke, kunezindlela ezahlukahlukene zokuthuthukisa ikhono langaphezulu le-polypropylene. Izindlela ezifanele zidinga ukukhethwa ngokuya ngezimo ezihlukene zohlelo lokusebenza. Lezi zindlela zingathuthukisa ngempumelelo ikhono eliphezulu lezinto ze-polypropylene, ngaleyo ndlela zithuthukise ukusebenza kwazo ezinhlelweni ezihlukahlukene.

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.
