Yintoni i-polypropylene?

1. ezahlukeneyo

Iindidi ze-polypropylene fiber ziquka i-filament (kuquka i-filament engaguqukiyo kunye ne-bulky deformed filament), i-staple fiber, i-mane fiber, i-membrane-split fiber, i-fiber e-hollow, i-profiled filament, ii-fibers ezahlukeneyo ezidibeneyo kunye namalaphu angalukwanga.Isetyenziselwa ikakhulu ukwenza iikhaphethi (kubandakanya ilaphu lesiseko sekhaphethi kunye ne-suede), ilaphu lokuhombisa, ilaphu lefenitshala, iintambo ezahlukeneyo, imicu, iminatha yokuloba, iifeelings ezifunxa ioyile, izixhobo zokuqinisa isakhiwo, izinto zokupakisha kunye namalaphu amashishini, njengelaphu lokucoca kunye ilaphu lengxowa.Ukongezelela, isetyenziswa ngokubanzi kwiimpahla.Inokudityaniswa kunye neentsinga ezahlukeneyo ukwenza iintlobo ezahlukeneyo zeelaphu ezidibeneyo.Emva kokunitha, kunokwenziwa iihempe, iimpahla zangaphandle, iimpahla zemidlalo, iikawusi, njl.

2. Iimpawu zeMichiza

Igama lenzululwazi le-polypropylene fiber lelokuba inyibilika kufutshane nedangatye, iyatsha, itshisa kancinane kude nomlilo kwaye ikhupha umsi omnyama.Isiphelo esiphezulu somlilo sityheli kwaye isiphelo esisezantsi siluhlaza okwesibhakabhaka, sikhupha ivumba lepetroleum.Emva kokutshiswa, uthuthu luqina, lungqukuva kunye namasuntswana amdaka atyheli, abuthathaka xa ejijelwe ngesandla.

3. Iimpawu ezibonakalayo

I-longitudinal plane ye-morphology polypropylene fiber ilula kwaye igudileyo, kwaye icandelo lomnqamlezo lijikelezileyo.

Inzuzo enkulu yoxinaniso lwefiber yepolypropylene kukukhanya kwayo, ukuxinana kwayo yi-0.91g / cm3 kuphela, eyona nto ilula kakhulu kwimicu yemichiza eqhelekileyo, ngoko ubunzima obufanayo be-polypropylene fiber bunokufumana indawo ephezulu yokugubungela kunezinye iifiber.

I-tensile ye-polypropylene fiber inamandla aphezulu, ubude obukhulu, imodyuli yokuqala ephezulu kunye nokunwebeka okugqwesileyo.Ke ngoko, i-polypropylene fiber inokumelana nokunxiba kakuhle.Ukongezelela, amandla amanzi e-polypropylene ngokusisiseko alingana namandla omileyo, ngoko yinto efanelekileyo yokwenza iminatha yokuloba kunye neentambo.

Kwaye inokukhanya kwe-hygroscopicity kunye nokudaya, ukugcinwa kobushushu obuhle;Phantse akukho kufunxa ukufuma, kodwa amandla okufunxa awomeleleyo, ukufunxa okucacileyo kokufuma kunye nokubila;Ifayibha yePolypropylene inokufunxa okuncinci kokufuma, phantse akukho kufunxa ukufuma, kwaye ukufuma kwakhona phantsi kweemeko zomoya jikelele kusondele ku-zero.Nangona kunjalo, inokufunxa umphunga wamanzi ngee-capillaries kwilaphu, kodwa ayinayo nayiphi na impembelelo yokufunxa.Ifayibha yePolypropylene inokudayi okulambathayo kunye nechromatography engaphelelanga, kodwa inokwenziwa yindlela yokufakwa kombala kwesisombululo sesitokhwe.

I-Acid-kunye ne-alkali-resistant polypropylene inokumelana nekhemikhali elungileyo yokungathobeki.Ngaphandle kwe-asidi ye-nitric egxininisiweyo kunye nesoda ye-caustic, i-polypropylene inokumelana kakuhle ne-asidi kunye ne-alkali, ngoko ikulungele ukusetyenziswa njengemathiriyeli yokucoca kunye nempahla yokupakisha.

Ukukhanya okukhanyayo, njl.Nangona kunjalo, ukusebenza okuchasene nokuguga kunokuphuculwa ngokudibanisa i-agent echasayo ngexesha lokujikeleza.Ukongeza, i-polypropylene ine-insulation elungileyo yombane, kodwa kulula ukuvelisa umbane ongatshintshiyo ngexesha lokulungiswa.I-Polypropylene ine-conductivity ephantsi ye-thermal kunye nokufakwa kakuhle kwe-thermal.

Amandla omsonto welastiki wepolypropylene aphezulu ngowesibini emva koko wenayiloni, kodwa ixabiso lawo yi-1/3 kuphela yenayiloni.Ilaphu elenziweyo linobungakanani obuzinzile, ukuxhathisa okulungileyo kwe-abrasion kunye no-elasticity, kunye nokuzinza okulungileyo kweekhemikhali.Nangona kunjalo, ngenxa yokuzinza kwayo okungahambi kakuhle kwe-thermal, ukunyanzeliswa kwe-insolation kunye nokuguga okulula kunye nomonakalo onqabileyo, i-anti-aging agents zihlala zongezwa kwi-polypropylene.

4. Usebenzisa

Ukusetyenziswa kwasekuhlaleni: Inokuphonwa icoceke okanye idityaniswe noboya, umqhaphu okanye i-viscose ukwenza zonke iintlobo zempahla yempahla.Ingasetyenziselwa ukunitha zonke iintlobo zeengubo ezinithiweyo ezinje ngeekawusi, iiglavu, iimpahla ezinithiweyo, ibhulukhwe ezinithiweyo, ilaphu lesitya, ilaphu lemnatha yeengcongconi, iqhiya, ukugquma okushushu, idiapers ezimanzi, njl.

Usetyenziso lwemizi-mveliso: iikhaphethi, iminatha yokuloba, iiseyile, ithumbu, ukuqiniswa kwekhonkrithi, amalaphu emizi-mveliso, amalaphu angalukwanga, njl. njl. Njengeekhaphethi, ilaphu lokucoca kwimizi-mveliso, iintambo, iminatha yokuloba, izixhobo zokuqinisa isakhiwo, iingubo ezifunxa ioli kunye nelaphu lokuhombisa, njl. Ukongeza, i-polypropylene fiber fiber ingasetyenziswa njengento yokupakisha. 

5. Isakhiwo

I-polypropylene fiber ayinayo amaqela ekhemikhali anokudibanisa kunye nedayi kwisakhiwo sayo se-macromolecular, ngoko kunzima ukudaya.Ngokwesiqhelo, ukulungiswa kwe-pigment kunye ne-polypropylene polymer zixutywa ngokulinganayo kwi-screw extruder ngendlela yokunyibilika kombala, kwaye ifayibha enemibala efunyenwe ngokujikeleza i-melt inokukhawuleza kombala.Enye indlela i-copolymerization okanye i-graft copolymerization nge-acrylic acid, i-acrylonitrile, i-vinyl pyridine, njl., ukuze amaqela amhlophe anokuthi adityaniswe nedayi afakwe kwii-polymer macromolecules, aze adayiwe ngokuthe ngqo ngeendlela eziqhelekileyo.Kwinkqubo yokuvelisa i-polypropylene fiber, kudla ngokuyimfuneko ukongeza izongezo ezahlukeneyo zokuphucula ukudaya, ukuchasana nokukhanya kunye nokumelana nomlilo.
