Hanyar Sulfurization Heat Jiyya na Sakandare da Kariya

Sulfurization na sakandare, wanda kuma aka sani da post-vulcanization ko mataki biyu sulfurization, wani tsari ne wanda samfuran roba ke ƙara zafi da ɓarna bayan sun kai wani matsayi na vulcanization, in babu tushen zafi. Makasudin wannan tsari shine don ƙara haɓaka samfuran roba, don haka haɓaka kayan aikin injin su da saiti na matsawa. Sulfurization na biyu yana da mahimmanci musamman ga samfuran roba da aka warkar da peroxide, kamar nitrile roba (NBR), roba ethylene-propylene (EPDM), roba acrylic, hydrogenated nitrile roba (HNBR), silicone roba, fluorine roba, da fluoro-silicone roba. Wannan tsari na iya ƙara haɓaka kaddarorin injina da saitin saiti na waɗannan kayan.

1. Hanyoyin Maganin Zafin Sulfurization na biyu
Maganin zafi na sulfurization na biyu ya ƙunshi matakai masu zuwa:

Preheating: Ana sanya samfuran roba a cikin tanda mai zafi don tsarin zafin jiki. Manufar preheating shine a ɗaga zafin samfuran roba zuwa matakin da ya dace don ingantattun halayen haɗin kai a cikin tsarin ɓarna na gaba. Yawan zafin jiki da lokacin preheating ana ƙaddara ta nau'in da ƙayyadaddun samfuran roba, gabaɗaya daga 100 ° C zuwa 150 ° C, tare da tsawon sa'o'i 1-2.

Vulcanization: Bayan preheating, samfuran roba ana sanya su a cikin tanderun vulcanization don aiwatar da vulcanization. Manufar vulcanization ita ce haifar da ƙwayoyin roba a cikin samfuran don ƙetare haɗin gwiwa, haɓaka aikin roba.
