Njirimara plastik nke roba nkịtị

1. Rọba eke
Ọ dị mfe inweta rọba eke. Ọ na-adịgide adịgide na obere ọwara draịva maleic nkịtị nwere obere ọwara draịva mbụ ma ọ dịghị mkpa ka e tinye ya na plastik. Ọ bụrụ na ọwara draịva Mooney nke ụdị ihe nrapado ndị ọzọ karịrị 60, a ka kwesịrị ịkpụzi ha. Mgbe ị na-eji ihe ngwakọta dị n'ime maka ịkpụzi, oge ahụ dị ihe dị ka nkeji 3-5 mgbe okpomọkụ ruru ihe karịrị 120 ℃. Mgbe ị na-agbakwunye ihe nrapado ma ọ bụ ihe nrapado, ọ nwere ike ime ka oge ịkpụzi plastik dị mkpụmkpụ ma melite mmetụta ịkpụzi plastik.
2. Styrene-butadiene
N'ozuzu, ike nke Mooney nke Styrene-butadiene dị n'etiti 35-60. Ya mere, Styrene-butadiene achọghịkwa ka ọ bụrụ plastik. Mana n'eziokwu, mgbe e mechara plastik ahụ, enwere ike ime ka mgbasa nke ihe na-agwakọta ya ka mma, nke na-enyere aka ime ka mma ngwaahịa ahụ ka mma. Karịsịa maka ngwaahịa roba sponge, Styrene-butadiene dị mfe ịfụ ụfụfụ mgbe e mechara plastik ahụ, nha afụ ahụ dịkwa otu.
3. Polybutadiene
Polybutadiene nwere ihe onwunwe nke mmiri oyi na-asọpụta, ọ dịghịkwa mfe ime ka mmetụta mmiri dị n'ime ya ka mma. Ugbu a, a na-achịkwa viscosity Mooney nke Polybutadiene a na-ejikarị eme ihe n'oge polymerization, yabụ enwere ike ịgwakọta ya ozugbo na-enweghị plastik.
4. Neoprene
Ọ dịghị mkpa ka e jiri plastik mee Neoprene, mana n'ihi ike ya dị elu, ọ na-enyere aka maka ọrụ. Okpomọkụ dị gịrịgịrị na-abụkarị 30 ℃ -40 ℃, nke dị mfe ịrapara na mpịakọta ahụ ma ọ bụrụ na ọ dị oke elu.
5. Ethylene propylene roba
N'ihi nhazi zuru oke nke eriri roba Ethylene propylene bụ isi, ọ na-esiri ike ime ka mkpụrụ ndụ gbawaa site na iji plastik. Ya mere, ọ dị mma ka a rụpụta ya ka o wee nwee ike ịdị mma nke Mooney na-enweghị mkpa ịkpụzi ya.
6. Rọba Butyl
Rọba Butyl nwere usoro kemịkalụ siri ike ma dị nro, obere ibu molekul na nnukwu mmiri mmiri, yabụ mmetụta plasticization mechanical adịghị mma. Enwere ike ịgwakọta rọba Butyl nwere obere viscosity Mooney ozugbo na-enweghị plasticization.
7. Roba Nitrile
Roba Nitrile nwere obere ike, ike siri ike na nnukwu mmepụta okpomọkụ n'oge a na-etinye plastik. Ya mere, a na-ejikarị obere okpomọkụ, obere ikike na plastik nkewa eme ihe n'ime igwe ihe mepere emepe iji nweta ezigbo nsonaazụ. Ekwesighi itinye rọba Nitrile na igwe ihe eji eme ihe n'ime. Ebe ọ bụ na rọba Nitrile dị nro nwere ike ịdị nro, enwere ike ịgwakọta ya ozugbo na-enweghị nchacha plastik.
