Njirimara plastik nke rọba nkịtị

1. Eke roba
Eke rọba dị mfe iji nweta plasticity.Viscosity na-adịgide adịgide na viscosity dị ala ọkọlọtọ nwoke roba nwere viscosity mmalite dị ala na n'ozuzu ọ dịghị mkpa ka ọ bụrụ plastik.Ọ bụrụ na viscosity Mooney nke ụdị ndị ọzọ nke ọkọlọtọ adhesives gafere 60, ha ka kwesịrị ịkpụzi.Mgbe ị na-eji igwekota n'ime maka ịkpụzi, oge dị ihe dịka 3-5 nkeji mgbe okpomọkụ ruru n'elu 120 ℃.Mgbe ị na-agbakwunye plasticizers ma ọ bụ plasticizers, ọ nwere ike ibelata oge plasticizing ma melite mmetụta plasticizing.
2. Styrene-butadiene
N'ikwu okwu n'ozuzu, Mooney viscosity nke Styrene-butadiene na-abụkarị n'etiti 35-60.Ya mere, Styrene-butadiene adịghịkwa achọ plasticizing.Ma n'ezie, mgbe plasticization, dispersibility nke compounding gị n'ụlọnga nwere ike mma, nke na-enyere aka melite ngwaahịa mma.Karịsịa maka ngwaahịa rọba sponge, Styrene-butadiene na-adị mfe ịfụ ụfụfụ mgbe emechara plastik, na nha afụ bụ otu.
3. Polybutadiene
Polybutadiene nwere ihe na-asọ oyi ma ọ dịghị mfe iji melite mmetụta plasticizing.Ka ọ dị ugbu a, a na-achịkwa viscosity Mooney nke Polybutadiene nke a na-ejikarị eme ihe n'ụzọ kwesịrị ekwesị n'oge polymerization, ya mere enwere ike ịgwakọta ya ozugbo na-enweghị plasticizing.
4. Neoprene
Neoprene n'ozuzu ọ dịghị mkpa ka ọ bụrụ plastik, ma n'ihi ịdị elu ya dị elu, ọ na-enye aka maka ịrụ ọrụ.The mkpa ngafe okpomọkụ bụ n'ozuzu 30 ℃ -40 ℃, nke dị mfe ịrapara na mpịakọta ma ọ bụrụ na ọ dị oke elu.
5. Ethylene propylene roba
N'ihi usoro juru eju nke isi yinye Ethylene propylene roba, ọ na-esiri ike ime ka mgbawa molekụla site na plastik.Ya mere, ọ bụ ihe amamihe dị na ya ịmepụta ya ka ọ nwee viscosity Mooney kwesịrị ekwesị na-enweghị mkpa ịkpụzi.
6. Butyl roba
Butyl rọba nwere usoro kemịkalụ kwụsiri ike ma dị nro, obere ịdị arọ molekụla na oke mmiri dị ukwuu, yabụ mmetụta plasticizing na-arụ ọrụ adịghị mma.Enwere ike ịgwakọta rubber Butyl nwere viscosity Mooney dị ala na-enweghị plastik.
7. Nitrile roba
Nitrile rọba nwere obere plasticity, elu ike na nnukwu okpomọkụ ọgbọ n'oge plastic.Ya mere, a na-ejikarị obere okpomọkụ, obere ikike na plasticating nkewa na-eme ihe na igwe igwe na-emeghe iji nweta nsonaazụ dị mma.E kwesịghị ịkaba rọba nitrile n'ime igwekota.Dị ka rọba Nitrile dị nro nwere ụfọdụ plastik, enwere ike ịgwakọta ya ozugbo na-enweghị nchacha plastik.
