Ibisobanuro:UV-1577 ni ultraviolet yinjiza urumuri (UVA) rwicyiciro cya hydroxyphenyl triazine yerekana ihindagurika rito cyane kandi rihuza neza na polymers zitandukanye, ibiyongerera imbaraga hamwe na resin.UV-1577 ituma polyikarubone na polyester bigera ku kurwanya cyane ikirere. kuruta ibisanzwe bya benzotriazole UV.UV-1577 ikwiranye nubwoko bwose bwimikorere ya polymers hamwe na alloys, nka PET, PBT, PC (umurongo nu mashami), polyether ester, PMMA, acolylic copolymers, PA, PS, SAN, ASA, polyolefin, ishimangirwa cyangwa idashimangiwe, yuzuye cyangwa ituzuye, flame-retardant cyangwa idafite flame-retardant, mucyo, byoroshye, n'ibindi
Ikoreshwa:DXSORB 1577 ikoreshwa nka stabilisateur yumucyo / UV ikurura polyethylene phthalate polymers igenewe gukoreshwa muguhuza ibiryo. Umuyoboro muke wa UV uhindagurika cyane hamwe na stabilisateur.Yemerera polyakarubone na polyester kugirango bigere ku guhangana n’ikirere kuruta ibisanzwe bya benzotriazole UV. Impengamiro nke ya chelate itanga ikoreshwa ryayo muri polymer irimo ibisigisigi bya catalizator. DXSORB 1577 (UV-1577) ikoreshwa nka stabilisateur yumucyo / UV ikurura polyethylene phthalate polymers igenewe gukoreshwa muguhura nibiryo.UV-1577 nigikorwa cyo hejuru cyane ultraviolet yumucyo urimo hydroxyphenyl triazine. Imikorere ya UV-1577 irashobora gutezimbere mugihe ihujwe na HALS.Polyalkene terephthaletes na naphthalates, umurongo wa polyakarubone y'umurongo hamwe n'amashami, ibice bya polifhenylene byahinduwe, hamwe na plastiki zitandukanye. Ibisabwa bijyanye nabyo birimo gukoresha ibikoresho bya homo-, co-, cyangwa terpolymer byubatswe mubikoresho bya termo- plastike. Polymer ivanga & alloys, nka PC / ABS, PC / PBT, PPE / IPS, PPE / PA hamwe na cololymers kimwe no gushimangirwa, kuzuzwa na / cyangwa flame idasubirwaho, bishobora kuba mucyo, bisobanutse kandi / cyangwa pigment.
Intangiriro irambuye
UV-1577ni ikoreshwa cyane ryibangamira urumuri rwa amine (HALS) rutanga uburyo bwiza bwo kwirinda ingaruka mbi ziterwa nimirasire ya ultraviolet (UV) no kwangirika kwa okiside. Bikunze gukoreshwa nk'inyongeramusaruro mu nganda zinyuranye, zirimo plastiki, ibifuniko, ibifunga, hamwe n’imyenda, kugirango byongerwe igihe kirekire nubuzima bwibikoresho byerekanwe hanze.
UV-1577, izwi kandi ku izina ry’imiti bis (1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate, ni iyumuryango wa amine wabujijwe kumashanyarazi. Ikora ikoresheje uburyo bwihariye bwibikorwa kugirango ikumire UV iterwa na polymers. Iyo ihuye nimirasire ya UV, UV-1577 ikora fototransformation idasubirwaho, ifata radicals yubusa ikanabitesha agaciro. Ibi birinda kwangirika kwa polymer no gutakaza nyuma yumutungo wumubiri, nkamabara agabanuka, gushushanya, hamwe no guturika hejuru.
Kimwe mu byiza byingenzi bya UV-1577 nuburyo bwinshi kandi buhuza hamwe na polymers nibikoresho byinshi. Irashobora gukoreshwa muri thermoplastique, nka polyolefine (urugero, polyethylene na polypropilene), polyester, polyakarubone, na PVC (chloride polyvinyl). Ifite kandi akamaro mumashanyarazi ya termosetting, nka polyurethanes, epoxy resin, hamwe na polyester idahagije. Ubu buryo butandukanye butuma UV-1577 ikwiranye nuburyo butandukanye, harimo firime, fibre, ibice byabumbwe, ibifuniko, ibifunga, hamwe na kashe.
UV-1577 itanga ubushyuhe buhebuje bwumuriro na okiside, ikomeza kuramba no gukora neza nubwo haba mubihe bibi ndetse no kumara igihe kinini imirasire ya UV. Irashobora kwihanganira ubushyuhe bwo hejuru butunganijwe mugihe cyo gukora polymer cyangwa gutegura ingingo nta kwangirika gukomeye.
Kugirango ugere ku mikorere myiza, UV-1577 ikoreshwa kenshi hamwe nubundi buryo butangiza urumuri, nka UV ikurura cyangwa antioxydants, kugirango itange ingaruka. Uku guhuza bifasha cyane kurinda UV kurinda no kuramba muri rusange ibikoresho.
Ni ngombwa gusuzuma dosiye yihariye nubuyobozi bwo gushyiramo UV-1577 mubikorwa bitandukanye. Abahinguzi n’abakoresha bagomba kwifashisha ibitabo bya tekiniki, umurongo ngenderwaho wibicuruzwa, hamwe ninganda nziza kubikorwa byakoreshejwe.
UV-1577 muri rusange ifatwa nkumutekano iyo ikoreshejwe, ibitswe, kandi ikoreshwa ukurikije amabwiriza nubuyobozi bukurikizwa. Nubwo bimeze bityo ariko, ni byiza buri gihe kugisha inama urupapuro rwumutekano (SDS) no kubahiriza amabwiriza y’ibanze kugira ngo bikemurwe neza.
Gusaba
UV-1577 ni imiti ivanze ikunze kwitwa tinuvin 1577 cyangwa bis (1,2,2,6,6-pentamethyl-4-piperidyl) sebacate. Ninzitizi ya amine yumucyo (HALS) ikoreshwa mubikorwa bitandukanye no mubikorwa. Dore bimwe mubikoreshwa byingenzi:
Guhindura Polymer:UV-1577 ikoreshwa cyane nka stabilisateur yumucyo mubicuruzwa bya polymer. Irinda polymers, nka plastiki hamwe nububiko, ingaruka mbi ziterwa nimirasire ya UV, harimo kwangirika, guhindura ibara, no gutakaza ibikoresho bya mashini. Ifasha kwagura igihe no gukomeza kugaragara ibikoresho bishingiye kuri polymer.
Ibitambaro n'amabara:UV-1577 yongewe kumyenda no gusiga irangi kugirango irusheho guhangana na UV kwangirika. Ifasha mukurinda amabara gucika, kugabanya ububengerane, hamwe no gutembera hejuru biterwa no guhura nizuba.
Plastike:Ikoreshwa mubikorwa bitandukanye bya pulasitiki, harimo polyolefine (nka polyethylene na polypropilene), polyurethanes, na PVC (chloride polyvinyl). UV-1577 itezimbere ikirere n’umucyo utuje wa plastiki, ibemerera kugumana imiterere yumubiri mugihe kinini cyo hanze.
Ibifunga hamwe na kashe:UV-1577 yinjizwamo ibifunga hamwe na kashe kugirango ibarinde kwangirika kwatewe na UV. Ibi bifasha kugumana imbaraga zifatika no kongera ubuzima bwa serivisi yibicuruzwa, cyane cyane mubisabwa hanze.
Fibre hamwe nimyenda:UV-1577 ikoreshwa kandi mu nganda z’imyenda kugirango irinde imyenda na fibre kwangirika kwimirase ya UV. Irinda ibara, kwangirika kwa fibre, no gutakaza imbaraga za mashini ziterwa na UV.
Ni ngombwa kumenya ko umubare wihariye nuburyo bukoreshwa bwa UV-1577 bishobora gutandukana bitewe nibicuruzwa n'inganda byihariye. Abahinguzi n’abakoresha UV-1577 bagomba guhora bakurikiza amabwiriza n'amabwiriza asabwa kugirango akoreshwe neza kandi akoreshwe.
