Ingabe kungcono ukusebenzisa i-PP noma i-PE ocingweni lwebhuloho lasekhaleni?

Ibhuloho elenziwe ngaphakathi lesifihla-buso line-single-core, kabili-core nayo yonke ipulasitiki. Akunandaba ukuthi hlobo luni lwezinto zepulasitiki ezisetshenziswayo, abanye abakhiqizi basebenzisa izinto zepulasitiki ze-PE, kanti abanye basebenzisa izinto zepulasitiki ze-PP.

Ngezansi sikhuluma ngobuhle nobubi be-PE ne-PP:

I-PP yi-polyethylene: ayinaphunga, ayinabuthi, inokumelana okushisa okuphansi okuhle kakhulu (i-usetemperature esezingeni eliphansi kakhulu ingafinyelela -70～-100℃), ikwazi ukumelana ne-acid kanye ne-alkalis, ayincibiliki kuma-solvents ajwayelekile ekamelweni lokushisa, futhi inamanzi amancane. , Ukufakwa kukagesi kuhle kakhulu; i-butpolyethylene izwela kakhulu ekucindezelekeni kwemvelo (amakhemikhali kanye nemiphumela yemishini), futhi inokumelana nokuguga okushisa okuncane.

I-PP impahla ispolyolefin: ayinabuthi, ayinambitheki, amandla ayo, ukuqina, ubulukhuni, ukumelana ne-heaters kungcono kune-polyethylene, ingasetshenziswa cishe kuma-degree ayi-100. Ithas izakhiwo ezinhle zikagesi nokufakwa okuvama kakhulu akuthintwa ngumswakama, kepha kuyaqina, kungagqoki, futhi kubudala kalula ezingeni eliphansi.

 

Okweikhala bridgewire, zombili zilungile. Impahla ye-PP inokuguquguquka okuhle. Le nto, i-likemetal wire, igoba futhi ikhubaze ngokusebenza kwamandla angaphandle, futhi ingakwazi ukugcina ukusebenza kwayo okuhle kakhulu.
