1. Irabha yendalo
Irabha yendalo kulula ukufumana iplastiki.I-viscosity eqhubekayo kunye ne-viscosity ephantsi yerabha yesilisa ine-viscosity yokuqala ephantsi kwaye ngokubanzi 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, okunceda 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.
