Izinto Ezisetshenziswa Kakhulu Ekukhiqizeni Izintambo Zokukhanya

Ukukhetha izinto ezifanele kubalulekile ukuqinisekisa ukuzinza kwesikhathi eside nokusebenza kwezintambo ze-optical. Izinto ezahlukene ziziphatha ngendlela ehlukile ngaphansi kwezimo zemvelo ezimbi kakhulu — izinto ezivamile zingase ziqhekeke futhi ziqhekeke emazingeni okushisa aphansi, kanti emazingeni okushisa aphezulu zingase zithambe noma ziguquguquke.

Ngezansi kunezinto eziningana ezisetshenziswa kakhulu ekwakhiweni kwekhebula le-optical, ngayinye inezinzuzo zayo kanye nezinhlelo zokusebenza ezifanele.

1. I-PBT (i-Polybutylene Terephthalate)

I-PBT iyinto esetshenziswa kakhulu kumashubhu akhululekile ekhebula le-optical.

Ngokushintsha — njengokwengeza izingxenye zeketanga eziguquguqukayo — ukuphuka kwayo ekushiseni okuphansi kungathuthukiswa kakhulu, kuhlangabeze kalula isidingo se--40 °C.
Iphinde igcine ukuqina okuhle kakhulu kanye nokuqina okulinganayo ngaphansi kwamazinga okushisa aphezulu.

Izinzuzo: ukusebenza okulinganiselayo, ukusebenza kahle kwezindleko, kanye nokusebenza kabanzi.

2. I-PP (i-Polypropylene)

I-PP inikeza ukuqina okuhle kakhulu ekushiseni okuphansi, ivimbela ukuqhekeka ngisho nasezindaweni ezibandayo kakhulu.
Iphinde inikeze ukumelana okungcono kwe-hydrolysis kune-PBT. Kodwa-ke, i-modulus yayo iphansi kancane, futhi ukuqina kwayo kubuthakathaka.

Ukukhetha phakathi kwe-PBT ne-PP kuncike ekuklanyweni kwesakhiwo sekhebula kanye nezidingo zokusebenza kwalo.

3. I-LSZH (I-Compound Ephansi Ye-Halogen Engenamusi)

I-LSZH ingenye yezinto ezisetshenziswa kakhulu emgodleni namuhla.
Ngezindlela zokwenziwa ze-polymer ezithuthukisiwe kanye nezithasiselo ezisebenzisanayo, ama-compound e-LSZH asezingeni eliphezulu angahlangabezana nokuhlolwa komthelela wokushisa okuphansi okungu--40 °C futhi aqinisekise ukuzinza kwesikhathi eside ku-85 °C.

Zine-langabi elibi kakhulu (likhiqiza intuthu ephansi futhi azikho amagesi e-halogen ngesikhathi sokusha), kanye nokumelana okunamandla nokuqhekeka kokucindezeleka kanye nokugqwala kwamakhemikhali.

Kuyindlela ekhethwayo yezintambo ezivimbela umlilo futhi ezinobungani nemvelo.

4. I-TPU (i-Thermoplastic Polyurethane)

Eyaziwa ngokuthi “inkosi yokumelana nokubanda nokuguguleka,” izinto zokubopha ze-TPU zihlala ziguquguquka ngisho nasemazingeni okushisa aphansi kakhulu ngenkathi zinikeza ukumelana okuhle kakhulu kokuguguleka, uwoyela, kanye nokuklebhuka.

Ilungele izintambo zokudonsa, izintambo zokumba, kanye nezintambo zezimoto ezidinga ukunyakaza njalo noma okumele zikwazi ukumelana nezimo ezibandayo ezinzima.

Kodwa-ke, kufanele kuqashelwe ukumelana nokushisa okuphezulu kanye ne-hydrolysis, futhi kunconywa amamaki ekhwalithi ephezulu.

5. I-PVC (i-Polyvinyl Chloride)

I-PVC iyindlela engabizi kakhulu yama-sheath ekhebula le-optical.
I-PVC ejwayelekile ivame ukuqina futhi ibe buthakathaka ngaphansi kuka--10 °C, okwenza ingafaneleki ezimweni zokushisa eziphansi kakhulu.
Izakhi ze-PVC ezingamelani nokubanda noma ezisezingeni eliphansi lokushisa zithuthukisa ukuguquguquka ngokufaka inani elikhulu lama-plasticizer, kodwa lokhu kunganciphisa amandla okusebenza kanye nokumelana nokuguga.

I-PVC ingacatshangelwa lapho ukusebenza kahle kwezindleko kuyinto eza kuqala futhi izidingo zokuthembeka kwesikhathi eside zingekho phezulu.

Isifinyezo

Ngayinye yalezi zinto zekhebula le-optical inikeza izinzuzo ezihlukile kuye ngohlelo lokusebenza.

Lapho uklama noma ukhiqiza izintambo, kubalulekile ukucabangela izimo zemvelo, ukusebenza kahle kwemishini, kanye nezidingo zesikhathi sesevisi ukuze ukhethe izinto ezifanele kakhulu.
