1. Rabha yechisikigo
Rabha yechisikigo iri nyore kuwana plasticity. Rabha remaleic rabha rinogara riripo uye rine viscous shoma rine viscous shoma yekutanga uye kazhinji harifanirwe kuiswa purasitiki. Kana viscous yemamwe marudzi emanamati akajairwa ikadarika 60, achiri kuda kuumbwa. Pakushandisa musanganiswa wemukati wekuumba, nguva yacho ingangoita maminetsi 3-5 kana tembiricha yasvika pamusoro pe120 ℃. Pakuwedzera mapurasitiki kana mapurasitiki, zvinogona kupfupisa nguva yepurasitiki zvakanyanya uye kuvandudza mhedzisiro yepurasitiki.
2. Styrene-butadiene
Kazhinji, huremu hweMooney hweStyrene-butadiene hunonyanya kuva pakati pe35-60. Saka, Styrene-butadiene haidiwo plasticization. Asi kutaura chokwadi, mushure me plasticization, kupararira kwemushonga unosanganisa zvinhu kunogona kuvandudzwa, izvo zvinobatsira kuvandudza mhando yechigadzirwa. Kunyanya kune zvigadzirwa zverabha rechiponji, Styrene-butadiene iri nyore kupumha furo mushure me plasticization, uye saizi yemabubbles yakafanana.
3. Polybutadiene
Polybutadiene ine hunhu hwekuyerera kwemvura inotonhora uye hazvisi nyore kuvandudza mhedzisiro yekuisa purasitiki. Parizvino, kupenya kweMooney kwePolybutadiene inowanzoshandiswa kwave kuchidzorwa munzvimbo yakakodzera panguva yekuisa polymer, saka inogona kusanganiswa zvakananga pasina kuisa purasitiki.
4. Neoprene
Neoprene haidi kuiswa purasitiki, asi nekuda kwekusimba kwayo kwakanyanya, inobatsira pakushanda. Tembiricha yekupfuura yakatetepa inowanzova 30 ℃ -40 ℃, izvo zviri nyore kunamira pamupumburu kana wakanyanya kukwira.
5. Rabha yeEthylene propylene
Nekuda kwechimiro chakazara cheketani huru yerabha yeEthylene propylene, zvakaoma kukonzera kutsemuka kwemamorekuru nekuisa purasitiki. Saka, zvinokurudzirwa kuigadzira kuti ive neMooney viscosity yakakodzera pasina chikonzero chekuiumba.
6. Rabha yeButyl
Rabha yeButyl ine chimiro chemakemikari chakasimba uye chakapfava, huremu hudiki hwemamorekuru uye kuyerera kukuru, saka mhedzisiro yekugadzirwa kwepurasitiki yemuchina haina kunaka. Rabha yeButyl ine viscosity yakaderera yeMooney inogona kusanganiswa zvakananga pasina kuiswa purasitiki.
7. Rabha yeNitrile
Rabha yeNitrile ine purasitiki diki, yakasimba uye inopisa zvakanyanya panguva yekuisa purasitiki. Saka, tembiricha yakaderera, kugona kwakaderera uye purasitiki yakakamurwa zvinowanzo shandiswa mugayo rakavhurika kuti zviwane mhedzisiro yakanaka. Rabha yeNitrile haifanirwe kuiswa purasitiki mumuchina wekusanganisa wemukati. Sezvo rabha yeNitrile yakapfava ine purasitiki yakati, inogona kusanganiswa zvakananga pasina kucheneswa kwepurasitiki.
