Ubwiza bwo hejuruagapira ko kurinda irangi (PPF)ikoresha Thermoplastic Polyurethane (TPU) nk'igikoresho cy'ingenzi cy'ingenzi, ari na cyo kigena kuramba kwa firime, ubwiza bwayo, n'imikorere yayo. Muri iki gihe, TPU ishyirwa mu byiciro by'umwihariko mu moko ya alifatique na aromatique, aho itandukaniro ryabyo rishingiye ku "kurwanya umuhondo." Imbonerahamwe iri hepfo igaragaza neza itandukaniro ry'ingenzi hagati y'ubwoko bubiri bwa TPU:
| Ibiranga | TPU ya Aliphatic | TPU ihumura neza |
|---|---|---|
| Imiterere y'Ubutabire | Nta mpeta za benzene zirimo (urugero, zishingiye kuri HDI), zihamye mu miterere yazo. | Irimo imiterere y'impeta ya benzene (urugero, ishingiye kuri MDI). |
| Ibiranga by'ingenzi | Ubudahangarwa bwiza bw'umuhondo: Irwanya imirasire ya UV igihe kirekire, ifite garanti ikunze kurenza imyaka 10. Imiterere ikomeye: Ifite ubucucike bwinshi bwa molekile, itanga ubudahangarwa bwiza bwo gushwanyagurika no kwangirika, ndetse n'imbaraga nyinshi zo gukurura no gukurura. | Ishobora guhinduka umuhondo: Impeta za Benzene zishobora gushonga iyo zishyizwe mu mirasire ya UV, bikaba byatera umuhondo ugaragara mu myaka 3-5. Ifite ubushobozi bwo koroha, ariko muri rusange nta mbaraga n'ubudahangarwa bifite ugereranije n'ubwoko bwa aliphatic. |
| Umwanya w'Isoko | Ibikoresho by'ibanze bya PPF yo mu rwego rwo hejuru, igiciro kiri hejuru. | Ibikoresho bisanzwe byo gushushanya PPF kuva ku rwego rwo hagati kugeza ku rwego rwo hasi, bihendutse cyane. |
Izindi nzego za TPU n'imiterere ya PPF
Uretse ibyo byiciro byavuzwe haruguru, TPU ishobora kandi gushyirwa mu byiciro bishingiye ku gice cyayo cyoroshye mu bwoko bwa polyester-based na polyether-based. TPU ishingiye kuri polyester itanga imbaraga nziza, ubudahangarwa, no kudahangarwa n'amavuta; TPU ishingiye kuri polyether itanga ubudahangarwa bwiza bwa hydrolysis no koroshya ubushyuhe. Ibikoresho bya PPF byo mu rwego rwo hejuru bigezweho akenshi bikoresha imiterere myiza kugira ngo bihuze iyi miterere. PPF yuzuye ni imiterere y'ibice byinshi. Uretse urwego rw'ibanze rwa TPU, harimo:
- Uburyo bwo gufatana: Butuma habaho gufatana gukomeye no gukuraho ibisigazwa bitagize icyo byangiza irangi ry'umwimerere. Busaba imbaraga nyinshi zo gufatana no kudakoresha imirasire ya UV. Ibicuruzwa byiza kandi byibanda ku kwirinda kwimuka kwa pulasitiki kugira ngo hirindwe ko kole yangirika.
- Ikoti ryo hejuru rikora neza: Iri inyuma cyane, rigena uburyo umukoresha akoresha akoresha. Imirimo y'ingenzi irimo kwivura (gukoresha hydrogen bonds mu ikoti risana udukoko duto dukoresheje ubushyuhe), imiterere yo kudakoresha amazi n'amaraso (yoroshya isuku), no gutanga imiterere myiza nko kugaragara neza cyangwa kugaragara neza.
Uburyo bwo guhitamo no kugurisha ibigezweho
Mu guhitamo PPF, uretse kwemeza ikoreshwa rya TPU ya aliphatic, ushobora no gutekereza kuri ibi bikurikira:
- Reba Garanti yemewe: Ibikoresho byizewe bya TPU bya aliphatic ubusanzwe biba bifite garanti yemewe y'imyaka 10 cyangwa irenga, bihamya neza ko birwanya umuhondo.
- Ibande ku ikoranabuhanga rya Top Coat: Top coat ifitanye isano itaziguye no kudakoresha amazi, ubushobozi bwo kwivura, no kuramba. Baza imikorere yihariye y'ikoti.
- Irinde imitego ihendutse: Witondere ibivugwa kuri "aliphatic TPU" ku giciro gito cyane, kuko bishobora kuba atari byo.
Ku bijyanye n'impinduka, hamwe n'ubwiyongere bw'abaguzi ku ireme no kuramba, TPU ifite ubushobozi bwo hejuru, ihagarariwe n'ibikoresho nkaLINGHUA TPU ikurikirana, irimo kuba amahitamo asanzwe ku isoko.
