Uluhlu lweSicelo

I-HP-669 isetyenziswa ngempumelelo kwishishini lerabha njenge-arhente yokudibanisa i-poly sulfur silane esebenza kabini.
I-HP-669 ingasetyenziswa kwinkqubo yerabha evulcanized enezizalisi ezifana ne-silica, i-fiberglass, i-talc powder, i-mica powder kunye nodongwe njenge-ejenti yokuqinisa. Ingaphucula iipropati zokuqinisa izizalisi kunye neepropati zokumelana nokurhawuzelelwa ngerabha.
Ifanelekile ukusetyenziswa njenge-rubber additive—i-vulcanizing agent kunye ne-activator kwiipolymers ezifana ne-NR, i-IR, i-SBR, i-BR, i-NBR kunye ne-EPDM.
Kwinkqubo ye-vulcanization, izinga lokudibanisa i-poly-sulfur alkyl liyafana nezinga le-deoxidizing le-sulfur, ngoko ke isebenza ukumelana ne-deoxidization ye-vulcanization, ize iphucule iipropati zokugoba eziguqukayo ezifana nokukhula kobushushu kunye nokwandiswa kwamaqhekeza. Iiathom ezine ze-sulfur zinokusebenza njenge-activator ye-vulcanization.
Kwiimeko ezitshintshayo nezizinzileyo, isetyenziselwa ukuvelisa ezi mveliso zerabha: itayara, ipayipi, iroli yerabha, ibhanti, intambo, izihlangu kunye neemveliso zokuseka oomatshini. Ingaphucula ukumelana nokurhawuzelela, ukumelana nokusika kunye noxinzelelo, inciphise ukulahleka kwe-hysteresis kunye ne-hygroscopicity, iphucule iimpawu zoomatshini kunye nokuncamathelisa, kwaye yonyuse ukusebenza kokuguga kobushushu, i-modulus kunye nobomi bokuguquguquka.
Ukongeza i-agent yokudibanisa i-sulfur-silane kwishishini leetayi zerabha, ayinciphisi nje kuphela umngcipheko wokubhoboka njengoko ubushushu buphezulu kakhulu xa usebenza kwindlela ekhawulezayo okanye ixesha elide, kodwa ikwanciphisa ukumelana nokuqengqeleka kweetayi, emva koko inciphise ukusetyenziswa kwepetroli, ubungakanani bokukhutshwa kwe-CO2 ukuze kuthintelwe ukukhuselwa kwendalo kokunciphisa ikhabhoni.
