Mpira wa Vulcameter

1. Ntchito ya vulcanizer ya rabara
Choyesera cha rabara cha vulcanization (chotchedwa vulcanizer) chimagwiritsidwa ntchito kusanthula ndikuyesa nthawi yopsa, nthawi yabwino ya vulcanization, kuchuluka kwa vulcanization, viscoelastic modulus ndi nthawi yosalala ya vulcanization ya njira ya rabara ya vulcanization. Fufuzani zida zopangira ndi zoyesera kuti muyesere mtundu wa chinthucho.
Opanga zinthu za rabara amatha kugwiritsa ntchito ma vulcanizer kuti ayesere kubwerezabwereza kwa zinthuzo komanso kukhazikika, komanso kupanga ndi kuyesa mapangidwe a rabara. Opanga amatha kuchita kafukufuku pamalopo pamzere wopanga kuti adziwe ngati mawonekedwe a vulcanization a gulu lililonse kapena mphindi iliyonse akukwaniritsa zofunikira za malondawo. Amagwiritsidwa ntchito kuyeza mawonekedwe a vulcanization a rabara yosavulidwa. Kudzera mu kugwedezeka kobwerezabwereza kwa rabara m'chibowo cha nkhungu, mphamvu yochitapo kanthu (mphamvu) ya chibowo cha nkhungu imapezeka kuti ipeze curve ya vulcanization ya torque ndi nthawi, ndipo nthawi, kutentha ndi kupanikizika kwa vulcanization zitha kutsimikiziridwa mwasayansi. Zinthu zitatuzi, ndizofunika kwambiri kuti pamapeto pake zitsimikizire mtundu wa chinthucho, komanso kudziwa mawonekedwe enieni a chinthucho.
2. Mfundo yogwirira ntchito ya vulcanizer ya rabara
Mfundo yogwirira ntchito ya chida ichi ndi kuyeza kusintha kwa shear modulus ya rabara panthawi ya vulcanization, ndipo shear modulus imagwirizana ndi kuchuluka kwa crosslinking, kotero zotsatira za muyeso zikuwonetsa kusintha kwa crosslinking degree ya rabara panthawi ya vulcanization, zomwe zitha kuyezedwa. Zofunikira monga ma viscosity oyamba, nthawi yowotcha, kuchuluka kwa vulcanization, nthawi yabwino ya vulcanization ndi oversulfur reversion.
Malinga ndi mfundo yoyezera, ikhoza kugawidwa m'mitundu iwiri. Mtundu woyamba ndi kugwiritsa ntchito mphamvu inayake ya amplitude ku rabara kuti muyese kusintha koyenera, monga Wallace vulcanizer ndi Akfa vulcanizer. Mtundu wina umagwiritsa ntchito amplitude inayake ku rabara. Kusintha kwa shear kumayesedwa, ndipo mphamvu yofanana ya shear imayesedwa, kuphatikiza rotor ndi rotorless disc oscillating vulcanizers. Malinga ndi magulu a ntchito, pali ma cone vulcanizers oyenera zinthu za siponji, ma vulcanizers oyenera kuwongolera khalidwe la fakitale, ma differential vulcanizers oyenera kafukufuku, ndi ma programmed temperature vulcanizers oyenera kutsanzira njira ya vulcanization ya zinthu zokhuthala ndikusankha momwe vulcanization ilili yabwino kwambiri. Tsopano zinthu zambiri zapakhomo ndi zamtunduwu za rotorless vulcanizer.
