1. Irabha yendalo
Irabha yendalo kulula ukuyifumana iplastiki. Irabha ye-maleic eqhelekileyo ene-viscosity engapheliyo kunye ne-viscosity ephantsi ine-viscosity yokuqala ephantsi kwaye ngokubanzi ayifuni ukufakwa iplastiki. Ukuba i-viscosity yeMooney yezinye iintlobo zezincamathelisi ezisemgangathweni idlula ama-60, kusafuneka ibunjwe. Xa usebenzisa umxube wangaphakathi wokubumba, ixesha limalunga nemizuzu emi-3-5 xa ubushushu bufikelela ngaphezulu kwe-120 ℃. Xa ukongeza ii-plasticizers okanye ii-plasticizers, kunokulinciphisa kakhulu ixesha le-plasticization kwaye kuphucule isiphumo se-plasticization.
2. I-Styrene-butadiene
Ngokubanzi, i-Mooney viscosity ye-Styrene-butadiene iphakathi kwama-35-60. Ke ngoko, i-Styrene-butadiene ayifuni plasticization. Kodwa eneneni, emva kokwenziwa iplastiki, ukusasazeka kwe-compound agent kunokuphuculwa, nto leyo enceda ukuphucula umgangatho wemveliso. Ingakumbi kwiimveliso zerabha yesiponji, i-Styrene-butadiene kulula ukuyifutha emva kokwenziwa iplastiki, kwaye ubungakanani beqamza buyafana.
3. I-Polybutadiene
I-Polybutadiene ineempawu zokuhamba komoya obandayo kwaye akulula ukuyiphucula impembelelo yokwenza iplastiki. Okwangoku, i-Mooney viscosity ye-Polybutadiene esetyenziswa rhoqo ilawulwa kuluhlu olufanelekileyo ngexesha lokwenza i-polymerization, ngoko ke ingaxutywa ngokuthe ngqo ngaphandle kokwenza iplastiki.
4. I-Neoprene
I-Neoprene ayidingi ukuba yenziwe iplastiki, kodwa ngenxa yokuqina kwayo okuphezulu, iluncedo ekusebenzeni. Ubushushu bokudlula obuncinci buhlala buyi-30 ℃ -40 ℃, okulula ukunamathela kwiroli ukuba iphezulu kakhulu.
5. Irabha ye-ethylene propylene
Ngenxa yesakhiwo esigcweleyo sekhonkco eliphambili lerabha ye-Ethylene propylene, kunzima ukubangela ukuqhekeka kweemolekyuli ngokufakelwa iplastiki. Ke ngoko, kuyacetyiswa ukuba yenziwe ukuze ibe ne-Mooney viscosity efanelekileyo ngaphandle kwesidingo sokuyibumba.
6. Irabha ye-Butyl
Irabha ye-Butyl inesakhiwo seekhemikhali esizinzileyo nesithambileyo, ubunzima obuncinci beemolekyuli kunye nokugeleza okukhulu, ngoko ke isiphumo sokwenza iplastiki ibe yeyoomatshini asisihle. Irabha ye-Butyl ene-viscosity ephantsi yeMooney ingaxutywa ngokuthe ngqo ngaphandle kokwenza iplastiki ibe yeyodwa.
7. Irabha yeNitrile
Irabha yeNitrile ineplastiki encinci, iqine kakhulu kwaye ivelisa ubushushu obukhulu ngexesha lokufakelwa iplastiki. Ke ngoko, ubushushu obuphantsi, umthamo ophantsi kunye nokufakelwa iplastiki okuhlukeneyo kudla ngokusetyenziswa kwi-open mill ukuze kufumaneke iziphumo ezilungileyo. Irabha yeNitrile akufuneki ifakwe iplastiki kwi-internal mixer. Njengoko irabha yeNitrile ethambileyo ineplastiki ethile, ingaxutywa ngokuthe ngqo ngaphandle kokucocwa kweplastiki.
