Imicu ye-polypropylene inezindlela ezimbili eziyinhloko zokusebenzisa ukhonkolo:
1) Vimbela ukuqhekeka kwepulasitiki kukhonkolo.
Ngesikhathi senqubo yokubeka nokuqinisa ikhonkrithi, ukulahleka kwamanzi angaphezulu kungaholela ekuncipheni nasekuqhekekeni kwepulasitiki. Ukwengeza imicu ye-polypropylene kukhonkrithi kungavimbela lokhu kuqhekeka. Ngenxa ye-modulus ephansi ye-polypropylene fibers uma kuqhathaniswa nekhonkrithi eqinile, ukuthuthuka kokumelana nokuqhekeka (ukuqhekeka okubangelwa ukucindezeleka kokushisa noma umthwalo womshini) kukhonkrithi eqinile kunqunyelwe, futhi ukuthuthuka kwamandla okunamathela kanye nokugoba akubalulekile, okunezinga elithile lokuthuthuka kokuqina kwekhonkrithi.
2) Thuthukisa ukumelana nomlilo kwekhonkrithi eqinile. Ngaphansi kwesenzo sokushisa okuphezulu, imicu ye-polypropylene izoqala ithambe futhi ishise, yakhe ama-pores amaningi kukhonkrithi. Amanzi aphehlwa ukushisa okuphezulu kukhonkrithi angakhishwa ngalezi pores, avimbele ukwakheka komfutho ophezulu wangaphakathi ngenxa yokuhwamuka kwamanzi futhi abangele ukuthi ikhonkrithi iqhume, ngaleyo ndlela ithuthukise kakhulu isikhathi sokumelana nomlilo kanye nezinga lekhonkrithi.
Imicu ye-polypropylene ingahlukaniswa ibe imicu emide, imicu emifushane, izindwangu ezingalukiwe ze-spunbond, izindwangu ezingalukiwe ezincibilikisiwe, njll.
(1) Ilula
Ubuningi be-polypropylene fiber bungu-0.90-0.92 g/cm, okuyiyona elula kakhulu kuzo zonke izinhlobo ze-chemical fibers, ilula ngo-20% kune-nylon, ilula ngo-30% kune-polyester, kanye nelula ngo-40% kunezinhlobo ze-viscose fibers. Ngakho-ke, ifaneleka kakhulu ukusetshenziswa njenge-filler yezingubo zasebusika noma njengendwangu yokushushuluza eqhweni, ukukhuphuka izintaba, nezinye izingubo.
(2) Amandla aphezulu, ukunwebeka okuhle, ukumelana nokuguguleka, kanye nokumelana nokugqwala
I-Polypropylene inamandla aphezulu (afanayo ezimweni ezomile nezimanzi) futhi iyinto efanelekile yokwenza amanetha okudoba kanye nezintambo; Ukumelana okuhle nokuguguleka, okufana namandla e-polyester ne-nylon, ngesilinganiso sokubuyela emuva esifana ne-nylon noboya, siphakeme kakhulu kunemicu ye-polyester ne-viscose; I-Polypropylene inokuqina okuncane kobukhulu, ithambekele ekuqhekekeni nasekuguquguqukeni, imelana nama-microorganisms, futhi ayibangeli umonakalo; Ukumelana namakhemikhali kuphakeme kunemicu evamile.
(3) Inezakhiwo zokuvikela ugesi kanye nokugcina ukufudumala
I-polypropylene fiber inokumelana okuphezulu kukagesi (7 × 10 Ω. cm) kanye nokuqhuba okuphansi kokushisa. Uma kuqhathaniswa nezinye izintambo zamakhemikhali, i-polypropylene fiber inokushisa okungcono kakhulu kukagesi kanye nokugcina ukufudumala, kodwa ithambekele ekukhiqizeni ugesi ongaguquki ngesikhathi sokucubungula.
(4) Ukusebenza kabi kokumelana nokushisa nokuguga
Imicu ye-polypropylene inezinga eliphansi lokuncibilika (165-173 ℃) kanye nokuqina okuncane ekukhanyeni nasekushiseni. Ngakho-ke, imicu ye-polypropylene inokumelana nokushisa okuncane, ukumelana nokuguga, futhi ayimelani noku-ayina. Kodwa-ke, isici sokulwa nokuguga singathuthukiswa ngokufaka i-ejenti yokulwa nokuguga ngesikhathi sokuphotha.
(5) Izakhiwo ezimbi zokumunca umswakama kanye nokufaka amabala
Izakhiwo zokumunca umswakama kanye nokudaya zemicu ye-polypropylene zimbi kakhulu phakathi kwemicu yamakhemikhali, cishe azikho ukumunca umswakama kanye nesilinganiso sokubuyisa umswakama esingaphansi kuka-0.03%. I-polypropylene e-Fine denier inomphumela oqinile wokumunca, futhi umhwamuko wamanzi ungasuswa ngama-capillary emicu. Ngemva kokwenziwa izingubo, induduzo yezingubo ingcono, ikakhulukazi ngemicu ye-polypropylene e-ultra-fine. Ngenxa yendawo engaphezulu, ukujuluka kungadluliselwa ngokushesha, kugcine isikhumba sikhululekile. Ngenxa yokumunca umswakama kanye nesilinganiso esiphansi sokuncipha kwemicu, izindwangu ze-polypropylene zinezici zokuwasha okulula nokomisa ngokushesha.
I-Polypropylene inezakhiwo ezimbi zokudaya, imibala ekhanyayo, kanye nokushesha okubi kokudaya. Amafutha ajwayelekile awakwazi ukuyidaya, futhi imicu eminingi ye-polypropylene enemibala ikhiqizwa ngokupenda ngaphambi kokusonta. Umbala wezinto ezingavuthiwe kanye nokuguqulwa kwefayibha kungasetshenziswa, futhi izinto ezihlanganisa uphethiloli zingaxutshwa ngaphambi kokusonta okuncibilikisiwe.
