1. Irabha yendalo
Irabha yendalo kulula ukufumana iplastiki. I-viscosity eqhubekayo kunye ne-viscosity ephantsi yerabha yesilisa ine-viscosity yokuqala ephantsi kwaye ayifuni ukuba yenziwe ngeplastiki. Ukuba i-Mooney viscosity yezinye iintlobo ze-adhesives eziqhelekileyo zidlula i-60, kusafuneka zibunjwe. Xa usebenzisa umxube wangaphakathi wokubumba, ixesha limalunga nemizuzu emi-3-5 xa ubushushu bufikelela ngaphezu kwe-120 ℃. Xa ufaka iiplasticizers okanye iiplasticizers, inokunciphisa kakhulu ixesha leplastiki kwaye iphucule umphumo weplastiki.
2. I-Styrene-butadiene
Ngokuqhelekileyo, i-Mooney viscosity ye-Styrene-butadiene iphakathi kwe-35-60. Ngoko ke, i-Styrene-butadiene nayo ayifuni iplastiki. Kodwa ngokwenene, emva kweplastiki, ukuchithwa kwe-agent edibeneyo kunokuphuculwa, oku kunceda ukuphucula umgangatho wemveliso. Ngokukodwa kwiimveliso zerabha zesipontshi, i-Styrene-butadiene kulula ukuphosa amagwebu emva kweplastiki, kwaye ubungakanani be-bubble bufana.
3. Polybutadiene
I-Polybutadiene inepropati yokuhamba okubandayo kwaye akulula ukuphucula umphumo weplastiki. Okwangoku, i-Mooney viscosity ye-Polybutadiene esetyenziswa ngokuqhelekileyo ilawulwa kwinqanaba elifanelekileyo ngexesha le-polymerization, ngoko inokuxutywa ngokuthe ngqo ngaphandle kweplastiki.
4. Neoprene
I-Neoprene ngokubanzi ayifuni ukuba yenziwe ngeplastiki, kodwa ngenxa yokuqina kwayo okuphezulu, iluncedo ekusebenzeni. Ubushushu bokupasa obubhityileyo buqhele ukuba yi-30 ℃ -40 ℃, ekulula ukuyincamathela kumqulu ukuba uphezulu kakhulu.
5. Irabha ye-ethylene propylene
Ngenxa yesakhiwo esigcweleyo sekhonkco eliphambili lerabha ye-Ethylene propylene, kunzima ukubangela ukuqhekeka kweemolekyuli ngeplastiki. Ke ngoko, kuyacetyiswa ukuba uyidibanise ukuze ube ne-money viscosity efanelekileyo ngaphandle kwesidingo sokubumba.
6. Irabha ye-butyl
Irabha ye-butyl inozinzo kunye nolwakhiwo lweekhemikhali ezithambileyo, ubunzima obuncinci bemolekyuli kunye nolwelo olukhulu, ngoko ke isiphumo soomatshini seplastikhi asisihle. Irabha ye-butyl ene-mooney viscosity esezantsi inokuxutywa ngokuthe ngqo ngaphandle kweplastiki.
7. Irabha ye-Nitrile
Irabha yeNitrile ineplastiki encinci, ukuqina okuphezulu kunye nesizukulwana esikhulu sobushushu ngexesha leplastiki. Ke ngoko, ubushushu obuphantsi, umthamo ophantsi kunye neplastikhi ecandiweyo ihlala isetyenziswa kwindawo yokusila ukuze kufumaneke iziphumo ezilungileyo. Irabha ye-Nitrile akufuneki ifakwe iplastiki kumxube wangaphakathi. Njengoko irabha yeNitrile ethambileyo ineplastiki ethile, inokuxutywa ngokuthe ngqo ngaphandle kokucokisa iplastiki.
