Izinto Ezisetshenziswa Ngokujwayelekile Ekwenziweni Kwekhebula Le-Optical

Ukukhetha izinto ezifanele kubalulekile ukuze kuqinisekiswe ukuzinza kwesikhathi eside nokusebenza kwezintambo ezibonakalayo. Izinto ezihlukene ziziphatha ngendlela ehlukile ngaphansi kwezimo ezimbi kakhulu zemvelo - izinto ezijwayelekile zingase zibe brittle futhi ziqhekeke emazingeni okushisa aphansi, kuyilapho emazingeni okushisa aphezulu zingase zithambe noma ziwohloke.

Ngezansi kukhona izinto ezimbalwa ezivame ukusetshenziswa ekwakhiweni kwekhebula le-optical, ngayinye inezinzuzo zayo kanye nezinhlelo zokusebenza ezifanele.

1. I-PBT (i-Polybutylene Terephthalate)

I-PBT iyinto esetshenziswa kakhulu kunazo zonke kumashubhu axegayo wekhebula elikhanyayo.

Ngokuguqulwa - njengokwengeza amasegimenti eketango aguquguqukayo - ukuqina kwayo kwezinga lokushisa eliphansi kungathuthukiswa kakhulu, kuhlangabezane kalula nemfuneko -40 °C.
Iphinde igcine ukuqina okuhle kakhulu kanye nokuzinza kwe-dimensional ngaphansi kwamazinga okushisa aphezulu.

Izinzuzo: ukusebenza okulinganiselwe, ukusebenza kahle kwezindleko, nokusebenza okubanzi.

2. PP (I-Polypropylene)

I-PP inikeza ukuqina okuhle kakhulu kwezinga lokushisa eliphansi, ukuvimbela ukuqhekeka ngisho nasezindaweni ezibandayo kakhulu.
Iphinde inikeze ukumelana okungcono kwe-hydrolysis kune-PBT. Kodwa-ke, i-modulus yayo iphansi kancane, futhi ukuqina kubuthakathaka.

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

3. I-LSZH (Inhlanganisela Yentuthu Ephansi Yeziro Halogen)

I-LSZH ingenye yezinto ezithandwa kakhulu ze-sheath ezisetshenziswa namuhla.
Ngokwakhiwa kwe-polymer okuthuthukisiwe nezithasiselo ze-synergistic, izinhlanganisela ze-LSZH zekhwalithi ephezulu zingahlangabezana nokuhlolwa komthelela wezinga lokushisa eliphansi -40 °C futhi kuqinisekiswe ukuzinza kwesikhathi eside ku-85 °C.

Zibonisa ukubambezeleka komlilo okuhle kakhulu (ukukhiqiza intuthu ephansi futhi awekho amagesi e-halogen ngesikhathi sokusha), kanye nokumelana okuqinile nokuqhekeka kwengcindezi nokugqwala kwamakhemikhali.

Kuyinketho ekhethwayo yamakhebuli anganqamuki ilangabi futhi angavumelani nemvelo.

4. TPU (Thermoplastic Polyurethane)

Eyaziwa ngokuthi "inkosi yokumelana nokubanda nokugqoka," i-TPU sheathing material ihlala iguquguquka ngisho namazinga okushisa aphansi kakhulu ngenkathi inikeza ukuhuzuka okuphezulu, uwoyela, nokumelana nezinyembezi.

Ilungele izintambo zokudonsa, izintambo zezimayini, nezintambo zezimoto ezidinga ukunyakaza njalo noma okumele zimelane nezimo ezibandayo ezibandayo.

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

5. I-PVC (i-Polyvinyl Chloride)

I-PVC iyindlela yokonga yamashethi ekhebula optical.
I-PVC evamile ivamise ukuqina futhi ibe brittle ngaphansi kuka -10 °C, iyenze ingafaneleki izimo zezinga lokushisa eliphansi kakhulu.
Ukwakhiwa kwe-PVC ukumelana nokubanda noma izinga lokushisa eliphansi kuthuthukisa ukuguquguquka ngokungeza inani elikhulu lamapulasitiki, kodwa lokhu kunganciphisa amandla emishini kanye nokumelana nokuguga.

I-PVC ingacatshangelwa lapho ukusebenza kahle kwezindleko kuyinto ebaluleke kakhulu futhi izidingo zokwethembeka zesikhathi eside zingekho phezulu.

Isifinyezo

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

Lapho udizayina noma ukhiqiza izintambo, kubalulekile ukucabangela izimo zemvelo, ukusebenza komshini, kanye nezimfuneko zempilo yesevisi ukuze ukhethe into efaneleke kakhulu.
