1,Isimiso sokusetshenziswa komsebenzi oyisisekelo
I-ANTI UV Poyester Dope Dywed Flay Filament ifinyelela umphumela wokuvikela (i-UPF Vaice ≥ 50+ Ukuhlanganiswa kokudaya kanye nomsebenzi we-anti UV kudinga ukulinganisa ukuqina nokuhambisana kokubili.
2,Ukuchazwa okuningiliziwe kwezinqubo zokukhiqiza ezibalulekile
(1)Ukuncipha okubonakalayo okuluhlaza nokuguqulwa
Ukukhetha ama-UV Ableber
Izidingo: Ubukhulu bezinhlayiyana ≤ 1 μ scm (ukugwema ukubhukuda okujikelezayo), ukuqina okushisayo ≥ 280 ℃ (ukumelana okushisa okuphezulu kwe-polymerization), ukuhambisana okuhle ne-polyester (ukuvikela i-pleipitation).
Ukuthayipha:
I-Organic Molecule Annorbents (njenge-UV-531): Kwethulwa ngentambo ehlanganisiwe, nge-wavelength yokutholwa kwe-290-400mm.
I-Nano Inorganic Powders (efana ne-Tio ₂, ZNO): Ngosayizi wezinhlayiyana eziyizinhlayiyana ezingama-50-100-1, uthuthukise ukuvikelwa ngokusakaza ukukhanya kwe-ultraviolet, futhi kudinga ukuguqulwa komhlaba (ukwelashwa kwe-ejenti ye-reen coupling) ukwenza ngcono ukuhlakazwa.
Ukulungiselela izingcezu ze-polyester
Ukuguqulwa okuhlanganisiwe: Ngesikhathi se-polyester melt malt polymerization (noma ngemuva kwe-polymerization eqinile), i-UV Absorbent Masterbatch ingezwe ngesilinganiso esingu-0.5% -2% futhi ihlakazeke ngokufana nge-twin-screw extrestering.
Ukuguqulwa kwe-Polymerization: Ama-monomers aqukethe amaqembu amunca i-UV (anjenge-benzotriazole p-hydroxybenzoate) afakwa kumaketanga ama-polyester ama-molecular ukufezekisa ukumelana kwe-UV okungapheli (izindleko eziphakeme, ezilungele imikhiqizo ephezulu).
(2)Inqubo yokuxubha kanye nokwelula
Ukulawulwa kwepharamitha yokuxubha
Izinga lokushisa nokubanda: Ncibilikisa izinga lokushisa lokuphothana ngu-285-300 ℃ (5-10
Isivinini: Ukujikeleza ngejubane eliphezulu (4000-5000 m / min) kuhlanganiswe ne-Devier enhle (15-50 DTEX) ukwandisa indawo ethile engaphezulu ye-fiber futhi kukhulise umphumela we-UV Shiving.
Ukwelula nokwakheka kahle
Ukwelula isilinganiso: 3.5-4.0 Times, ithuthukisa i-fiber crystallity (i-crystaltaltity ≥ 45%), yehlisa iziphambeko ze-amorphous, futhi igweme ukungena kwe-UV.
Ukushisa kokushisa okushisa: 180-200 ℃ (10-20 ℃ ephansi kune-polyester ejwayelekile), ukuvikela ukubola okushisayo kokutholwa nokulawula isilinganiso se-shrinkage ≤ 8%.
(3)Inqubo yokudaya (Ukulawula Okusemqoka Ukuhambelana)
Ukukhetha izindlela zokudaya
Umbala ohlaza okotshani + uvimba ukumelana: Ngaphambi kokuxubha, i-Pigment Masterbatch kanye ne-UV Absorber kungezwa ngasikhathi sinye, kufanelekile imikhiqizo emnyama (emnyama, eluhlaza okwesibhakabhaka, i-pigment ngokwayo ingasiza ekuhlazeniseleni), ngokuvikelwa kombala okuhlala isikhathi eside.
Post stain + anti UV ukuqeda:
Ukusabalalisa udayi kufanele kusetshenziselwe izinga lokushisa eliphakeme nokwesokucindezela okuphezulu (130 ℃ × 30min), kanye nodayi oluhle lokuhambisana nokuzithoba kufanele kukhethwe ama-Dyes, ukugwema ukusabela kwe-PhotoCHemical phakathi kodayi lwe-anthraquinone.
Ngemuva kokudaya, cwilisa ukukhipha i-antiolet yokuqedela i-ejenti (efana ne-UV esuselwa emanzini angu-UV Amuncunt Lotions) ilungele imikhiqizo yombala okhanyayo, kepha ukumelana kwayo kokugeza akwehlise (imvamisa inani le-UPF liyancipha ngo-20% ngemuva kwezikhathi ezi-5 zokugeza).
Ukusebenza kwenqubo yokudaya
Ukulawulwa kwe-PH: I-PH ye-DEY BATHA ingu-4.5-5,5 (buthaka acidic) ukuvikela umuzwa ekuboshweni ngaphansi kwezimo ze-alkali (ezinjenge-benzophanones zitholakala kalula nge-hydrolyzed at Ph> 7).
Ukukhetha okungeziwe: Faka ama-ejenti we-nonic weleveli (anjenge-polyoxyethyeneyleneline ye-polyoxyethylenenenenene) ukugwema ukukhokhiswa kokuthuthumela phakathi kwama-ionic angezeli kanye nokuthathwa, okungathinta ukuhlakazwa.
(4)Ukulawula okusebenzayo okusebenzayo
Ukuxhumana phakathi kokumunca kanye nodayi
Ama-UV Amuncter angancintisana nodayi wezingosi ezibophayo kwimicu, eholela ekunciphiseni ekujuleni kokudaya (k / s incishiswe ngo-10% -15%), okudinga ukunxeshezelwa ngenxa yokwanda kwedayi donsa noma ukufeza ifomula.
Isibonelo, lapho ukudaya okujulile okuluhlaza okwesibhakabhaka, inani lokudayiswa okujwayelekile kwe-polyester esetshenzisiwe lingu-2% (i-owf), kanye nenani le-UV elimelana ne-polyester lidinga ukukhungezeka libe ngu-2,5% -3% (owf).
Ukuvuka okukhanyayo okukhanyayo
Ama-UV Afforbers angasiza ekuthuthukiseni ukushesha okukhanyayo kwamadayi (njengokukhulisa izinga lokumelana nokukhanya okukhanyayo kokusabalalisa udayi obomvu 60 ku-UV avimbela imicu kusuka ezingeni 3 kuya ku-4), njengoba ukugaya kunciphisa ukulimala kwemisebe ye-UV kuma-molecule e-UV.
3,Ubunzima bezobuchwepheshe nezisombululo
Ukungafani okumpofu kokutholwa
Inkinga: I-AGGGGOMEROR iholela ekutheni i-spinch cleage futhi yehlise amandla e-fiber.
Isixazululo: Ukwemukela ubuchwepheshe bokugaya kweNANO (ukugaya ngesigayo sesihlabathi kuya ku-D50 ≤ 500nm) + Ukuguqulwa komhlaba (okufana nokuhlanganisa i-Tio ₂ nge-Stearic acid).
Ukufana okunganele kokubala
Inkinga: Ama-Ambunts athinta izinga lokudaya amadayi, okuholela ekukhishini.
Uhlelo lokuhlenga: Ukushisa okuhlukanisiwe nokudaya (njengokushisa ngo-1 ℃ / min ngo-30-60 ℃ no-2 ℃ / min ngo-60-130 ℃), ukunweba isikhathi sokufakwa kwemizuzu engama-40.
Ukuqina Okusebenzayo
Inkinga: Ukumelana kabi kokulimala kwama-anti UV Agents ngemuva kokuqeda.
Isixazululo: Ukuvuselelwa okusebenzayo (okufana nokuthola ama-UV Amunbents aqukethe amaqembu e-epoxy) asetshenziselwa ukukhomba ngokubumbana ngemicu ngokuphendula okuxhumeka ngokuwela, ngokuhlanza kwezikhathi ezingama-20.
4,Izimo zohlelo lokusebenza kanye nokuguqulwa kwenqubo
Izingubo zangaphandle: Okubaluleke kakhulu kufanele kunikezwe inqubo yokufaka imibala ngesisombululo sokuqala kanye nokuxubana okuhlanganisiwe, kucatshangelwa ukuvikelwa kwe-UV nokushesha kombala (njengezingubo zokuhamba ngezintambo kanye nezingubo zokuvikela ilanga).
Umhlobiso Wangaphakathi: Thumela inqubo yokuqeda i-anti UV + ukudaya, ngezindleko eziphansi (njengamakhethini, ilanga), kepha kudinga ukulungiswa okujwayelekile.
Izokwelapha: CO DEDIED NOMUDITID UQEQESHE UKUZE UVUSELE UKUVULA (njengezingubo zokuhlinzwa namabhandeji), ngokuhambisana namazinga okuphepha ebanga lezokwelapha.
