Vulcanization
Ugbu a, ụzọ vulcanization nke nnukwu na ọkara roba rollers ka bụ vulcanization tankị. Ọ bụ ezie na agbanweela ụdị nrụgide dị nro, ọ ka na-apụ n'anya ibu ọrụ dị arọ nke ibugharị, ibuli na ibupụ.

Iji gbochie roba na isi ígwè ka ha ghara ịdị n'otu n'ihi mbelata dị iche iche nke ọdịiche dị n'etiti roller roba na isi roba, vulcanization na-ejikarị usoro ikpo ọkụ na mmụba nrụgide nwayọ, oge vulcanization na-adịkwa ogologo karịa oge vulcanization nke roba ahụ chọrọ. . Iji nweta vulcanization otu n'ime na n'èzí, ma mee ka conductivity okpomọkụ nke isi ígwè na roba yie, roller roba buru ibu na-anọ n'ime tankị ahụ ruo awa 24 ruo 48, nke bụ ihe dị ka ugboro 30 ruo 50 oge vulcanization roba nkịtị.
A na-agbanwe obere na obere rọba ka ọ bụrụ vulcanization nke e ji plate vulcanizing press molding vulcanization, na-agbanwe usoro vulcanization ọdịnala nke rọba rollers kpamkpam. N'afọ ndị na-adịbeghị anya, ejirila igwe ịkpụzi ihe n'ime ihe e ji ebu ihe na vulcanization vacuum, enwere ike imeghe ma mechie ebu na akpaghị aka. A ka mma nke ukwuu n'ọkwa nke igwe na akpaaka, oge vulcanization dịkwa mkpụmkpụ, arụmọrụ mmepụta dị elu, ịdị mma nke ngwaahịa ahụ dịkwa mma. Karịsịa mgbe a na-eji igwe ịkpụzi ihe n'ime ihe e ji ebu ihe n'ime ihe, a na-ejikọta usoro abụọ nke ịkpụzi na vulcanization n'otu, a pụkwara ime ka oge ahụ dị mkpụmkpụ ruo nkeji 2 ruo 4, nke aghọwo ntụziaka dị mkpa maka mmepe nke mmepụta rọba rollers.
Ugbu a, rọba mmiri mmiri nke polyurethane elastomer (PUR) na-anọchite anya ya etolitela ngwa ngwa n'imepụta rọba rollers, ma mepee ụzọ ọhụrụ nke ihe na usoro mgbanwe maka ya. Ọ na-eji ụdị ịwụsa mmiri iji wepụ ọrụ ịkpụzi ihe dị mgbagwoju anya na akụrụngwa vulcanization buru ibu, na-eme ka usoro mmepụta nke rọba rollers dị mfe nke ukwuu. Agbanyeghị, nsogbu kachasị bụ na a ga-eji ebu eme ihe. Maka nnukwu rollers rọba, karịsịa maka ngwaahịa nkeonwe, ọnụ ahịa mmepụta na-abawanye nke ukwuu, nke na-eweta nnukwu nsogbu na nkwalite na ojiji.
Iji dozie nsogbu a, usoro ọhụrụ nke rola rọba PUR na-enweghị imepụta ebu apụtala n'afọ ndị na-adịbeghị anya. Ọ na-eji polyoxypropylene ether polyol (TDIOL), polytetrahydrofuran ether polyol (PIMG) na diphenylmethane diisocyanate (MDl) dị ka ihe eji emepụta ihe. Ọ na-emeghachi omume ngwa ngwa mgbe agwakọtara ma kpalie ya, a na-awụsakwa ya n'ime rọba rola metal nke na-agbagharị nwayọọ nwayọọ. , A na-emezu ya nzọụkwụ site na nzọụkwụ mgbe a na-awụsa ma na-agwọ ya, n'ikpeazụ a na-emepụta rola rọba. Usoro a abụghị naanị obere usoro, ọ dị elu na nhazi na akpaaka, kamakwa ọ na-ewepụ mkpa maka ebu buru ibu.
