-Sizayo
Incazelo:I-UV-1577 iyi-ultraviolet light absorber (UVA) wekilasi le-hydroxyphenyl ntathu elibonisa ukuguquguquka okuphansi kakhulu kanye nokuhambisana okuhle nama-polymen ama-polymebonate kanye nama-polyesters ukufeza ukumelana okuphezulu kwe-nzotriazole UV I-Forbers.uv-1577 ilungele zonke izinhlobo zama-polymers aphezulu nama-alloys, anjenge-pet, ptby, pc (i-polymer, i-san, i-sang, i-flame-retabarant, i-flame-retame-retabant, esobala, iguqulwe, njll.
Sebenzisa:I-DXSORB 1577 isetshenziswa njenge-stabilizer / i-UV ethotsheni ye-polyethylene phthalate polymers okuhloswe ngayo ukusetshenziswa nokudla. I-UV ephansi kakhulu i-UV ekhanyayo i-ablorber ne-stabilizer.Allows polycarbonate kanye nama-polyesters ukufezekisa ukumelana okuphezulu ku-isimo sezulu kunama-benzotriazole UV atholakalayo. Ukuthambekela okuphansi kwe-chelate kuvumela ukusetshenziswa kwayo ekwakhiweni kwama-polymer aqukethe izinsalela ze-catalyst. I-DXSORB 1577 (UV-1577) isetshenziswa njenge-stabilizer / UV anyombo ye-polyethylene perthalate polymers okuhloswe ngayo ukusetshenziswa nge-ood.uv-1577 ingukusebenza okuphezulu okukhanyayo okuqukethe i-hydroxyphenyl light Absorber Group equkethe i-Hydroxyphenyl Triazine Group equkethe i-Hydroxyphenyl Triazine Group equkethe i-Hydroxyphenyl Triazine Group equkethe i-Hydroxyphenyl Light Absorber. Ukusebenza kwe-UV-1577 kungalungiselelwe lapho kuhlangene ne-hels.polyalkene terephthaletes kanye nama-naphthalates, ama-polycarbonates, ama-polyphenene ether compounds, kanye nezimpawu ezahlukahlukene zokusebenza okuphezulu. Izicelo ezifanele futhi zifaka ukusetshenziswa kwama-homo-, co-, noma ama-accosymer ahlukene ama-ackarons ezintweni ezisetshenziswayo zeplastiki. I-Polymer ihlangana nama-alloys, njenge-PC / ABS, i-PC / PBT, i-PPE / IPS, i-PPE / PPE / amakhompiyutha ancishisiwe kanye / noma amalangabi abuyiselwe emuva, okuthi / noma umbala.
Isingeniso Esinemininingwane
UV-1577Ingabe i-Amine Light Amine Stabilizer esetshenziswayo ebanzi (i-HALLS) enikeza ukuvikela okusebenzayo emiphumeleni elimazayo ye-Ultraviolet (UV) nemisebe ye-oxidative. Isetshenziswa kakhulu njengezengezo ezimbonini ezahlukahlukene, kufaka phakathi amapulasitiki, ukumboza, ukunamathela, kanye nezindwangu, ukukhulisa ukuqina kanye nokuphila kwezinto zokwakha ezivezwe ezindaweni ezingaphandle.
I-UV-1577, eyaziwa nangokubizwa kwayo kwamakhemikhali BIS (1,2,2,6,6-Pentamethyl-4-piperidinyl) Sebacate, ingeyomndeni wakwa-Amine ovinjelwe e-Stivilizer. Isebenza ngendlela eyingqayizivele yesenzo ukuvikela ukonakaliswa kwe-UV kuma-polymers. Lapho kuvezwa ngemisebe ye-UV, i-UV-1577 ithola i-phototranrations eguqukayo, ithumba ama-radicals wamahhala futhi ayivikeleki. Lokhu kuvimbela ukonakaliswa kwe-polymer kanye nokulahleka okulandelayo kwezindawo ezibonakalayo, njengokuphela kombala, ukufona, kanye nemifantu engaphezulu.
Enye yezinzuzo ezisemqoka ze-UV-1577 yinzuzo yazo ehlukahlukene kanye nokuhambisana nohlu olubanzi lwama-polymers kanye nezinto zokwakha. Ingasetshenziswa kuma-thermoplastics, anjenge-polyolefins (isib. Polyethylene kanye ne-polypropylene), polysters, polycarbonases, ne-PVC (polyvinyl chloride). Kuyaphumelela futhi kuma-thermosetting resins, anjenge-polyurethanes, ama-epoxy resins, kanye nama-poyester resen angenasisekelo. Lokhu kuguqulwa kwenza i-UV-1577 ilungele izicelo ezahlukahlukene, kufaka phakathi amafilimu, imicu, izingxenye ezibunjiwe, ukumboza, ukunamathela kanye nama-sealan.
I-UV-1577 inikeza ukuqina okuhle kakhulu okushisayo kanye nokuqina, kuqinisekisa ukuphila kwayo kwayo kanye nokusebenza kahle noma ngaphansi kwezimo ezinzima nokuchayeka isikhathi eside kwemisebe ye-UV. Ingamelana namazinga okushisa aphakanyisiwe ngesikhathi sokukhiqizwa kwe-polymer noma ukulungiswa kwendatshana ngaphandle kokuwohloka okukhulu.
Ukuthola ukusebenza okuphezulu, i-UV-1577 ivame ukusetshenziswa ngokuhlanganiswa nezinye izibalo zokukhanya, ezinjengezithaba ze-UV noma ama-antioxidants, ukuhlinzeka ngomphumela we-synergistic. Le nhlanganisela isiza ukukhulisa ukuvikelwa kwe-UV nokuqina kokuqina kwezinto zokwakha.
Kubalulekile ukubheka imihlahlandlela ethile kanye nemihlahlandlela yokwakheka kokufaka i-UV-1577 ibe izinhlelo ezihlukile. Abakhiqizi nabasebenzisi kufanele babhekise ezincwadini zobuchwepheshe, imihlahlandlela yomkhiqizo, nemikhuba engcono kakhulu yamazinga wokusebenzisa anconyiwe.
I-UV-1577 ithathwa njengephephile lapho isingathwa, igcinwe, futhi isetshenziswe ngokuya ngemithethonqubo esebenzayo kanye nemihlahlandlela. Kodwa-ke, kuhlale kungcono ukuthintana neshidi ledatha yokuphepha (SDS) futhi uhambisane nemithetho yendawo ukuqinisekisa inqubo efanelekile yokuphatha nezinqubo zokulahla.
Isicelo
I-UV-1577 iyingxenye yamakhemikhali evame ukwaziwa ngokuthi yiTineuvin 1577 noma i-BIS (1,2,2,6,6-Pentamethyl-4-PiperIdyl) Sebacate. Kuyinto evinjelwe i-Amine Light Stabilizer (ama-hels) asetshenziswa kwizimboni ezahlukahlukene nasezisetshenzisweni. Nazi ezinye zezinto zalo eziphambili:
Ukuqina kwe-polymer:I-UV-1577 isetshenziswa kabanzi njenge-stabilizer elikhanyayo emikhiqizweni ye-polymer. Ivikela ama-polymers, njengamapulasitiki kanye nezimbobo, emiphumeleni eyingozi yemisebe ye-UV, kufaka phakathi ukuwohloka, ukudicilela phansi, kanye nokulahlekelwa yizakhiwo zemishini. Kuyasiza ukunweba isikhathi sokuphila futhi kugcinwe ukubukeka kwezinto ezenzelwe ama-polymer.
Imidwebo nopende:I-UV-1577 yengezwa embonweni nopende ukuthuthukisa ukumelana kwabo nokuwohloka kwe-UV. Kuyasiza ekuvikeleni umbala ophela, ukuncishiswa kwesicwebezela, kanye nokushiswa komhlaba okubangelwa ukuvezwa elangeni.
I-Plastics:Isetshenziswa ezinhlelweni ezahlukahlukene zepulasitiki, kufaka phakathi ama-polyolefins (njenge-polyethylene ne-polypropylene), ama-polyurethanes, ne-PVC (polyvinyl chloride) imikhiqizo. I-UV-1577 ithuthukisa isimo sezulu kanye nokuqina okukhanyayo kwalawa mapulasitiki, okubavumela ukuba balondoloze izakhiwo zabo ezibonakalayo ngenxa yezikhathi ezengeziwe zokuvezwa kwangaphandle.
Izinamathiseli nama-sealants:I-UV-1577 ifakwa ezinamatheliso kanye nama-sealants ukuze abavikele ekuwohlokeni okubangelwa i-UV. Lokhu kusiza ukugcina amandla anamathela futhi kunwebe impilo yenkonzo yale mikhiqizo, ikakhulukazi kwizicelo zangaphandle.
Imicu nezindwangu:I-UV-1577 nayo isetshenziswa embonini yezindwangu ukuvikela izindwangu nemicu evela kumonakalo wemisebe ye-UV. Kuvimbela ukudilizwa, ukucekelwa phansi kwe-fiber, kanye nokulahleka kwamandla okusebenza okubangelwa ukuvezwa kwe-UV.
Kubalulekile ukuqaphela ukuthi amanani athile nezindlela zohlelo lokusebenza ze-UV-1577 zingahluka ngokuya ngomkhiqizo othize kanye nomkhakha. Abakhiqizi kanye nabasebenzisi be-UV-1577 kufanele bahlale belandela imihlahlandlela kanye nemigomo yokuxhasa ngokufanele nokusebenzisa.
