Umkhiqizo

I-Silicone Masterbatch SC920 Ithuthukisa Ukucutshungulwa Nokukhiqiza Ezintweni zekhebula ze-LSZH kanye ne-HFFR

Usizo lokucubungula i-silicone SC 920 lusizo olukhethekile lokucubungula i-silicone lwezinto zekhebula ze-LSZH ne-HFFR okuwumkhiqizo owakhiwe ngamaqembu akhethekile asebenzayo ama-polyolefin kanye ne-co-polysiloxane. I-polysiloxane kulo mkhiqizo ingadlala indima yokubambelela ku-substrate ngemuva kokuguqulwa kwe-copolymerization, ukuze ukuhambisana ne-substrate kube ngcono, futhi kube lula ukuhlakazeka, futhi amandla okubopha abe namandla, bese inika i-substrate ukusebenza okuhle kakhulu. Isetshenziswa ukuthuthukisa ukusebenza kokucubungula kwezinto ohlelweni lwe-LSZH kanye ne-HFFR, futhi ifanele izintambo ezikhishwe ngesivinini esikhulu, ithuthukise ukuphuma, futhi ivimbele isenzakalo sokukhipha njengobubanzi bentambo engazinzile kanye nokushelela kwezikulufo.

Izinzuzo

1, Uma isetshenziswa ohlelweni lwe-LSZH kanye ne-HFFR, ingathuthukisa inqubo yokukhipha i-mouth die cumulation, ifanelekela ukukhishwa kwe-cable ngesivinini esikhulu, ithuthukise ukukhiqizwa, ivimbele ububanzi bokungazinzile komugqa, ukushelela kwesikulufa kanye nezinye izinto ezikhipha i-extrusion.

2, Thuthukisa kakhulu ukugeleza kokucubungula, nciphisa i-viscosity yokuncibilika enqubweni yokukhiqizwa kwezinto ezigcwele i-halogen ezingenawo umlilo ezivimbela umlilo, nciphisa i-torque kanye nokucubungula kwamanje, nciphisa ukuguguleka kwemishini, nciphisa izinga lokukhubazeka komkhiqizo.

3, Nciphisa ukunqwabelana kwekhanda elidayiwe, nciphisa izinga lokushisa lokucubungula, qeda ukuqhekeka kokuncibilika kanye nokubola kwezinto zokusetshenziswa okubangelwa izinga lokushisa eliphezulu lokucubungula, yenza ubuso bentambo ekhishwe kanye nekhebula bube bushelelezi futhi bukhanye, nciphisa i-friction coefficient yobuso bomkhiqizo, uthuthukise ukusebenza okubushelelezi, uthuthukise ukukhanya kobuso, unikeze umuzwa obushelelezi, uthuthukise ukumelana nokuklwebheka.

4, Nge-polymer ye-silicone ekhethekile eguquliwe njengesithako esisebenzayo, thuthukisa ukusabalala kwezithiyo zomlilo ohlelweni, kuhlinzeke ngokuqina okuhle kanye nokungafuduki.

Isetshenziswa kanjani

Ngemva kokuxuba i-SC 920 ne-resin ngokwesilinganiso, ingakhiwa ngqo noma isetshenziswe ngemuva kokuhlanganiswa. Inani elinconywayo lokwengeza: Uma inani lokwengeza lingu-0.5%-2.0%, lingathuthukisa ukucutshungulwa, ukugeleza kanye nokukhululwa komkhiqizo; Uma inani lokwengeza lingu-1.0%-5.0%, izakhiwo zomphezulu womkhiqizo zingathuthukiswa (ubushelelezi, ukuqeda, ukumelana nokuklwebheka, ukumelana nokuguguleka, njll.)
