I-polyurethane elastomer luhlobo lwezinto ezisetyenziswa kakhulu, inokuguquguquka okuhle, ihlala ixesha elide kwaye iyamelana nokuguguleka, ngoko ke isetyenziswa kakhulu kuzo zonke iinkalo zobomi. Enye yezinto ezibalulekileyo ekuvelisweni kwee-polyurethane elastomers kukusetyenziswa kwee-catalysts ezikhawulezisa ukusabela kweekhemikhali ngexesha lokwenziwa kwezinto zokugqibela. Ezi catalysts zibalulekile ekulawuleni inkqubo ye-polymerization, ukuqinisekisa ukuba iipropati ezifunwayo ze-elastomer ziyafezekiswa. Phakathi kwee-catalysts ezahlukeneyo ezikhoyo, i-MXC-A33 inomxube owahlukileyo onokusetyenziswa kuluhlu olubanzi lwee-polyurethane foams kunye nee-elastomers.
Yintoni iI-MXC-A33?
I-MXC-A33 yi-polyurethane catalyst ephucula impendulo phakathi kwee-polyols kunye nee-isocyanates, ezizezona zinto ziphambili zezinto ze-polyurethane. I-catalyst yenziwe yi-33% TEDA (triethylene diamine) kunye ne-67% DPG (i-monoconjugated dipropylene glycol). Le fomyula ithile inika ukusebenza okuphezulu kwimveliso yee-polyurethane foams kunye nee-elastomers.
- I-TEDA (i-Triethylenediamine): I-catalyst ye-tertiary amine esebenza kakuhle kakhulu ekhuthaza impendulo ye-gelling phakathi kwamaqela e-hydroxyl kunye ne-isocyanate.
- I-DPG (i-Monoconjugated Dipropylene Glycol): Isinyibilikisi esinceda ukunciphisa i-viscosity nokuphucula ukuxubana kwezinto, ukuqinisekisa inkqubo yokusabela egudileyo.
Ukusetyenziswa kwi-Polyurethane Elastomers
I-MXC-A33 isetyenziswa kakhulu ekuveliseni ii-elastomers ze-polyurethane ngenxa yesiphumo sayo esilinganiselayo se-catalytic, esiqinisekisa ukuba i-polymerization reaction yenzeka ngesantya esilawulwayo. Le reactivity elawulwayo ibalulekile ekuveliseni ii-elastomers ezineempawu zoomatshini ezifunekayo ezifana nokuthamba, amandla okutsalwa kunye nokumelana nokuguguleka.
I-catalyst ikhuthaza ukwakheka kwezakhiwo zepolymer ezidibeneyo ezifanayo, ezinokuhlangabezana nokusebenza kwee-elastomers kwizicelo ezifuna amandla. Ii-elastomers zePolyurethane ezenziwe ngeMXC-A33 zisetyenziswa kakhulu kwiindawo zeemoto, kwiirola zemizi-mveliso, nakwiiseal ezisebenza kakuhle, ezibeka iimfuno eziphezulu ekuqineni nasekuthambekeni kwazo.
Isiphelo
Ukusetyenziswa kweiikhatalyst ze-polyurethaneNjengeMXC-A33 kwimveliso ye-elastomer, yinto ebalulekileyo ekuqinisekiseni ukusebenza kunye nokuthembeka kwezixhobo. Indibaniselwano yayo eyahlukileyo yeTEDA kunye neDPG yenza ukuba isebenze kakhulu kwizicelo zefoam kunye ne-elastomer, nto leyo evumela abavelisi ukuba bavelise iimveliso ezikumgangatho ophezulu nezihlala ixesha elide kwiimveliso ezahlukeneyo.
