Plasticity nke roba

Ikike nke rọba na-emezigharị n'okpuru ike ndị dịpụrụ adịpụ ma nọgide na-enwe nrụrụ ya ọbụna mgbe a kpochapụrụ ihe ndị dị n'èzí ka a na-akpọ plasticity. A na-akpọ usoro ịba ụba nke rọba plasticization. Rubber nwere plasticity iji jikọta ya na ihe mgbakwunye dị iche iche n'oge agwakọta; Ọ dị mfe ịbanye n'ime akwa akwa akwa n'oge nhazigharị; Ọ nwere mmiri mmiri dị mma n'oge extrusion na injections.

Ihe achọrọ plastik nke raw rubber kwesịrị ekwesị, ma nnukwu ma ọ bụ obere nwere ike inwe mmetụta ọjọọ. Nnukwu plasticity nke raw roba nwere ike ibelata njirimara anụ ahụ na nke arụ ọrụ nke rọba vulcanized, na-emetụta ojiji nke ngwaahịa ahụ. Ọ bụrụ na plasticity nke raw rubber dị oke ala, ọ ga-eme ka ihe isi ike na nhazi ma mee ka ọ bụrụ na ọ na-esiri ike ịgwakọta ihe rubber ahụ nke ọma; Na-atụgharị, elu nke ngwaahịa emechara ọkara adịghị mma mgbe ị na-agbanye; Nnukwu ntaramahụhụ shrinkage na-eme ka o sie ike ịghọta nha nke ngwaahịa emechachara; N'oge a na-atụgharị, ọ na-esiri ike ka teepu nrapado na-agbanye n'ime akwa ahụ, na-eme ka ọkpụkpụ nke eriri eriri ahụ kwụgidere ma na-ebelata nchikota n'etiti akwa ihe.
