1. Rabha yakasikwa
Natural rabha iri nyore kuwana plastiki.Constant viscosity uye yakaderera viscosity yakajairwa maleic rubha ine yakaderera yekutanga viscosity uye kazhinji haidi kuve purasitiki.Kana iyo Mooney viscosity yemamwe marudzi emhando yekunamatira inodarika makumi matanhatu, ichiri kuda kuumbwa.Paunenge uchishandisa musanganiswa wemukati wekuumba, nguva yacho ingangoita 3-5 maminetsi apo tembiricha inosvika pamusoro pe120 ℃.Kana uchiwedzera plasticizers kana plasticizers, inogona zvakanyanya kupfupisa nguva yeplasticizing uye kugadzirisa mapurasitiki ekuita.
2. Styrene-butadiene
Kazhinji kutaura, iyo Mooney viscosity yeStyrene-butadiene kazhinji iri pakati pe35-60.Naizvozvo, Styrene-butadiene zvakare haidi plasticizing.Asi chaizvoizvo, mushure mekugadzirwa kwepurasitiki, iyo dispersibility yemusanganisi wekubatanidza inogona kuvandudzwa, iyo inobatsira kuvandudza chigadzirwa chemhando.Kunyanya kune zvigadzirwa zverabha zveponji, Styrene-butadiene iri nyore kupupa mushure mepurasitiki, uye saizi yebubble iyunifomu.
3. Polybutadiene
Polybutadiene ine inotonhora yekuyerera pfuma uye haisi nyore kuvandudza iyo plasticizing maitiro.Parizvino, iyo Mooney viscosity yeinowanzo shandiswa Polybutadiene yakadzorwa munzvimbo yakakodzera panguva yepolymerization, saka inogona kusanganiswa zvakananga pasina plasticizing.
4. Neoprene
Neoprene kazhinji haidi kuve yepurasitiki, asi nekuda kwekuoma kwayo, inobatsira pakushanda.Tembiricha yekupfuura yakatetepa kazhinji 30 ℃ -40 ℃, iri nyore kunamatira kumupumburu kana wakanyanya kukwirira.
5. Ethylene propylene rubber
Nekuda kwechimiro chakazara cheketani huru yeEthylene propylene rubber, zvakaoma kukonzeresa kuputika kwemamorekuru nepurasitiki.Naizvozvo, zvinokurudzirwa kuisanganisa kuti ive yakakodzera Mooney viscosity pasina kudiwa kwekuumbwa.
6. Butyl rabha
Butyl rabha ine yakagadzikana uye yakapfava kemikari chimiro, diki molecular huremu uye yakakura fluidity, saka iyo mechanic plasticizing maitiro haina kukura.Butyl rabha ine yakaderera Mooney viscosity inogona kusanganiswa yakananga pasina plasticizing.
7. Nitrile rabha
Nitrile rabha ine diki purasitiki, kusimba kwakanyanya uye yakakura kupisa chizvarwa panguva yepurasitiki.Naizvozvo, tembiricha yakaderera, yakaderera huwandu uye yakakamurwa mapurasitiki anowanzo shandiswa muguyo rakashama kuti uwane mhedzisiro yakanaka.Nitrile rabha haifanirwe kuve yakashongedzwa mune yemukati musanganiswa.Sezvo rabha yakapfava yeNitrile ine imwe purasitiki, inogona kusanganiswa yakananga pasina kunatswa kwepurasitiki.
