Kedu ọrụ nke ihe na-akpali akpali na mmeghachi omume polymerization onwe nke hydroxyethyl acrylate?
Iji mee ka mmeghachi omume nke onwe-polymerization mee, a chọrọ okpomọkụ kwesịrị ekwesị mbụ. N'ozuzu, oke okpomọkụ maka imepụta onwe-polymerization nke hydroxyethyl acrylate Ọ DỊ MMA dị n'etiti 30°C na 60°C. Ọ bụrụ na okpomọkụ dị oke ala, mmeghachi omume ahụ ga-adị nwayọ ma ọ bụ ọbụna ghara ime. Ọ bụrụ na okpomọkụ dị oke elu, mmeghachi omume ahụ nwere ike ịdị oke ike, na-eme ka o sie ike ijikwa usoro mmeghachi omume ahụ ma na-ebute ngwaahịa na-adịghị akwụsi ike. Ya mere, ijikwa okpomọkụ dị oke mkpa! Na mgbakwunye na okpomọkụ, ìhè bụkwa ihe dị mkpa. Hydroxyethyl acrylate na-emeghachi omume nke ukwuu na ìhè ultraviolet (UV), ìhè UV nwekwara ike ịkwalite nkewa nke njikọ abụọ ya, si otú a na-amalite mmeghachi omume polymerization. N'okpuru radiation UV, polymerization onwe nke hydroxyethyl acrylate hea ga-adị ngwa ngwa. Ọ bụrụ na anyị ejiri oriọna UV ma ọ bụ kpughee ya na anyanwụ, ọ ga-enweta polymerization onwe ngwa ngwa. Chee echiche, n'okpuru anyanwụ, molekul ndị a dị ka ịgba egwu, na-ejikọta ngwa ngwa iji mepụta ihe ọhụrụ. Na mgbakwunye na okpomọkụ na ìhè, nhọrọ nke catalyst na-emetụtakwa ọnụego na mmetụta nke mmeghachi omume polymerization onwe. Anyị ga-agbakwunye ụfọdụ ihe na-akpalite peroxide, dị ka hydrogen peroxide, ma ọ bụ ngwakọta azo dị ka azobisisobutyronitrile (AIBN). Ihe mkpali ndị a nwere ike ibelata okpomọkụ mmalite nke mmeghachi omume onwe-polymerization nke ọma, na-enye ya ohere ịga n'ihu nke ọma ọbụlagodi na okpomọkụ dị ala. Ha na-arụ ọrụ dị ka ihe na-eme ka ihe na-eme ngwa ngwa! Na-enweghị ihe na-eme ka ihe na-eme ngwa ngwa, mmeghachi omume ahụ nwere ike ịdị nwayọ ma ọ bụ ọbụna ghara ime. Ya mere, a pụghị ileghara ọrụ nke ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe na-eme ka ihe ghara ịdị mma anya.
