Iyini i-polypropylene?

1. ezihlukahlukene

Izinhlobo ze-polypropylene fiber zihlanganisa i-filament (okuhlanganisa i-filament engaguquki kanye ne-bulky deformed filament), i-staple fiber, i-mane fiber, i-membrane-split fiber, i-fiber engenalutho, i-fiber ephrofayili, imicu ehlukahlukene eyinhlanganisela nezindwangu ezingalukiwe.Isetshenziselwa kakhulu ukwenza okhaphethi (okubandakanya i-carpet base cloth kanye ne-suede), indwangu yokuhlobisa, indwangu yefenisha, izintambo ezihlukahlukene, imicu, amanetha okudoba, izinsimbi ezimunca uwoyela, izinto zokuqinisa izakhiwo, izinto zokupakisha nezindwangu zezimboni, njengendwangu yokuhlunga kanye isikhwama indwangu.Ngaphezu kwalokho, isetshenziswa kakhulu ezingutsheni.Ingahlanganiswa nemicu ehlukahlukene ukwenza izinhlobo ezahlukene zezindwangu ezihlanganisiwe.Ngemuva kokunitha, kungenziwa amahembe, izingubo zangaphandle, izingubo zezemidlalo, amasokisi, njll. I-quilt eyenziwe nge-polypropylene hollow fiber ilula, ifudumele futhi iyanwebeka.

2. Izakhiwo zamakhemikhali

Igama lesayensi le-polypropylene fiber ukuthi incibilika eduze nelangabi, iyavutha, ivutha kancane kancane emlilweni futhi ikhiphe intuthu emnyama.Ingxenye engenhla yelangabi iphuzi kanti ingxenye engezansi iluhlaza okwesibhakabhaka, ikhipha iphunga le-petroleum.Ngemva kokusha, umlotha uqinile, uyindilinga kanye nezinhlayiya ezinsundu ngokuphuzi, ezintekenteke lapho usongwe ngesandla.

3. Izinto ezibonakalayo

I-longitudinal plane ye-morphology polypropylene fiber iyisicaba futhi ibushelelezi, futhi ingxenye ephambanayo iyindilinga.

Inzuzo enkulu yefiber ye-polypropylene ye-density ukuthungwa kwayo kokukhanya, ukuminyana kwayo kungu-0.91g/cm3 kuphela, okuwuhlobo olulula kakhulu lwemicu yamakhemikhali evamile, ngakho isisindo esifanayo se-polypropylene fiber ingathola indawo ephakeme yokumboza kuneminye imicu.

I-tensile polypropylene fiber inamandla amakhulu, ubude obukhulu, i-modulus yokuqala ephezulu kanye nokunwebeka okuhle kakhulu.Ngakho-ke, i-polypropylene fiber inokumelana okuhle kokugqoka.Ngaphezu kwalokho, amandla amanzi e-polypropylene ngokuyisisekelo alingana namandla omile, ngakho-ke kuyinto ekahle yokwenza amanetha okudoba nezintambo.

Futhi ine-hygroscopicity elula kanye nokudaya, ukugcinwa kokufudumala okuhle;Cishe akukho ukumuncwa komswakama, kodwa amandla okumunca aqinile, ukumuncwa komswakama okusobala nokujuluka;Ifayibha ye-polypropylene inokumunca okuncane komswakama, cishe akukho ukumuncwa komswakamo, futhi umswakama obuyayo ngaphansi kwezimo ezivamile zomkhathi usondele ku-zero.Nokho, ingakwazi ukumunca umhwamuko wamanzi ngama-capillaries esendwangu, kodwa ayinawo umphumela wokumunca.I-polypropylene fiber inokudaya okungekuhle kanye ne-chromatography engaphelele, kodwa ingenziwa ngendlela yokufaka umbala wesixazululo sesitoko.

I-polypropylene emelana ne-Acid ne-alkali inokumelana nokugqwala kwamakhemikhali okuhle.Ngaphandle kwe-nitric acid egxilile kanye nesoda ye-caustic egxilile, i-polypropylene inokumelana okuhle ne-asidi ne-alkali, ngakho ilungele ukusetshenziswa njengesisefo nezinto zokupakisha.

Ukushesha okukhanyayo, njll. I-Polypropylene inokushesha okumpofu kokukhanya, ukungazinzi kahle kwe-thermal, ukuguga kalula futhi akukho ukumelana noku-ayina.Kodwa-ke, ukusebenza kwe-anti-aging kungathuthukiswa ngokungeza i-ejenti elwa nokuguga ngesikhathi sokuphotha.Ngaphezu kwalokho, i-polypropylene ine-insulation kagesi enhle, kodwa kulula ukukhiqiza ugesi omile ngesikhathi sokucubungula.I-Polypropylene ine-conductivity ephansi yokushisa kanye nokufakwa kahle kwe-thermal.

Amandla entambo yokunwebeka ye-polypropylene ephezulu ingeyesibili kuphela kunaleyo inayiloni, kodwa inani layo liyi-1/3 kuphela yaleyo yenayiloni.Indwangu ekhiqiziwe inosayizi ozinzile, ukumelana okuhle nokuhuzuka nokunwebeka, kanye nokuzinza okuhle kwamakhemikhali.Kodwa-ke, ngenxa yokungaqini kahle kwe-thermal, ukumelana ne-insolation kanye nokulimala okulula nokuguga, ama-anti-aging agents avame ukungezwa ku-polypropylene.

4. Isebenzisa

Ukusetshenziswa komphakathi: Kungaphothwa kuhlanzeke noma kuhlanganiswe noboya, ukotini noma i-viscose ukwenza zonke izinhlobo zezinto zokugqoka.Ingasetshenziselwa ukunitha zonke izinhlobo zezingubo zokuluka ezifana namasokisi, amagilavu, ama-knitwear, amabhulukwe aboshiwe, indwangu yesitsha, indwangu yenethi yomiyane, i-quilt, ukugxusha okufudumele, amanabukeni amanzi, njll.

Izicelo zezimboni: okhaphethi, amanetha okudoba, amaseyili, amapayipi, izinto eziqinisa ukhonkolo, izindwangu zezimboni, izindwangu ezingalukiwe, njll. Okufana nokhaphethi, indwangu yokuhlunga yezimboni, izintambo, amanetha okudoba, izinto zokuqinisa izakhiwo, izingubo zokulala ezimunca uwoyela nendwangu yokuhlobisa, njll. Ngaphezu kwalokho, ifilimu yefilimu ye-polypropylene ingasetshenziswa njengento yokupakisha. 

5. Isakhiwo

I-polypropylene fiber ayinawo amaqembu amakhemikhali angahlangana namadayi esakhiweni sawo se-macromolecular, ngakho-ke kunzima ukudaya.Imvamisa, ukulungiswa kwe-pigment kanye ne-polypropylene polymer kuxutshwa ngokulinganayo ku-screw extruder ngendlela yokuncibilika kombala, futhi i-fiber enombala etholwe ngokuphotha okuncibilikayo inokushesha kombala okuphezulu.Enye indlela i-copolymerization noma i-graft copolymerization nge-acrylic acid, i-acrylonitrile, i-vinyl pyridine, njll., ukuze amaqembu e-polar angahlanganiswa nodayi angeniswe kuma-polymer macromolecules, bese adaywa ngokuqondile ngezindlela ezivamile.Enqubweni yokukhiqiza i-polypropylene fiber, ngokuvamile kuyadingeka ukwengeza izithasiselo ezihlukahlukene ukuze kuthuthukiswe ukudaya, ukumelana nokukhanya nokumelana nomlilo.
