A kataliz\u00e1torok term\u00e9szet\u00e9b\u0151l fakad, hogy egy heves reakci\u00f3 sor\u00e1n lecs\u00f6kkentik a h\u0151m\u00e9rs\u00e9kletet?<\/p>\n

A kataliz\u00e1tor l\u00e9nyege nem az, hogy egy heves reakci\u00f3 sor\u00e1n lecs\u00f6kkentse a h\u0151m\u00e9rs\u00e9kletet, hanem az, hogy a reakci\u00f3 aktiv\u00e1l\u00e1si energi\u00e1j\u00e1nak cs\u00f6kkent\u00e9se r\u00e9v\u00e9n felgyors\u00edtsa a reakci\u00f3 sebess\u00e9g\u00e9t. Az aktiv\u00e1l\u00e1si energia az a minim\u00e1lisan sz\u00fcks\u00e9ges energiamennyis\u00e9g, amely egy reakt\u00e1ns term\u00e9kk\u00e9 alak\u00edt\u00e1s\u00e1hoz sz\u00fcks\u00e9ges, \u00e9s \u00fagy is felfoghat\u00f3, mint az az energiahat\u00e1r, amelyet a reakt\u00e1nsnak a reakci\u00f3 sor\u00e1n le kell gy\u0151znie. Egy k\u00e9miai reakci\u00f3ban, ha a reakt\u00e1nsok nem tudj\u00e1k lek\u00fczdeni az energiahat\u00e1rt, a reakci\u00f3 nem tud lezajlani. A kataliz\u00e1tor megk\u00f6nny\u00edti a reakci\u00f3t az\u00e1ltal, hogy cs\u00f6kkenti a reakt\u00e1nsok sz\u00e1m\u00e1ra az energiahat\u00e1r lek\u00fczd\u00e9s\u00e9hez sz\u00fcks\u00e9ges energiamennyis\u00e9get.<\/p>\n

B\u00e1r a kataliz\u00e1tor cs\u00f6kkenti a reakci\u00f3 aktiv\u00e1l\u00e1si energi\u00e1j\u00e1t, nem cs\u00f6kkenti az er\u0151szakos reakci\u00f3 h\u0151m\u00e9rs\u00e9klet\u00e9t. A kataliz\u00e1torok lehet\u0151v\u00e9 teszik, hogy a reakci\u00f3k enyh\u00e9bb k\u00f6r\u00fclm\u00e9nyek k\u00f6z\u00f6tt j\u00e1tsz\u00f3djanak le, de nem cs\u00f6kkentik a reakci\u00f3 h\u0151m\u00e9rs\u00e9klet\u00e9t sem, ha az nagy mennyis\u00e9g\u0171 h\u0151energi\u00e1t ig\u00e9nyel. Ezenk\u00edv\u00fcl a kataliz\u00e1torok felgyors\u00edthatj\u00e1k az er\u0151szakos reakci\u00f3k sebess\u00e9g\u00e9t is, amelyek magas h\u0151m\u00e9rs\u00e9kletet vagy nyom\u00e1st eredm\u00e9nyezhetnek. A kataliz\u00e1tor szerepe teh\u00e1t nem az, hogy a reakci\u00f3t a h\u0151m\u00e9rs\u00e9klet cs\u00f6kkent\u00e9s\u00e9vel gyors\u00edtsa, hanem az, hogy a reakci\u00f3 sebess\u00e9g\u00e9t a reakci\u00f3partnerek k\u00f6z\u00f6tti k\u00f6lcs\u00f6nhat\u00e1sok megv\u00e1ltoztat\u00e1s\u00e1val gyors\u00edtsa.<\/p>\n

A legt\u00f6bb PUR (forr\u00f3 olvad\u00e9kragaszt\u00f3) alapvet\u0151en kataliz\u00e1tort haszn\u00e1l, bis-morfolin-dietil-\u00e9ter DMDEE, CAS-sz\u00e1m: 6425-39-4.<\/p>\n

Ennek mennyis\u00e9ge a k\u00e9pletben nagyon kicsi, \u00e1ltal\u00e1ban 0,05%-0,5% k\u00f6z\u00f6tt van, de nagyon fontos szerepet j\u00e1tszik: el\u0151seg\u00edti az izocian\u00e1t \u00e9s a v\u00edzg\u00e1z k\u00f6z\u00f6tti reakci\u00f3t, felgyors\u00edtja a kem\u00e9nyed\u00e9s sebess\u00e9g\u00e9t.<\/p>\n

Sokf\u00e9le poliuret\u00e1n kataliz\u00e1tor l\u00e9tezik, mi\u00e9rt a DMDEE?<\/p>\n

Ennek oka, hogy nemcsak a PUR kem\u00e9nyed\u00e9si sebess\u00e9g\u00e9t jav\u00edtja, hanem j\u00f3 h\u0151stabilit\u00e1st is biztos\u00edt, azaz magas h\u0151m\u00e9rs\u00e9kleten viszonylag lass\u00fa viszkozit\u00e1sn\u00f6veked\u00e9st.<\/p>\n

\u00c9s nincs kataliz\u00e1tor PUR, mint a legt\u00f6bb kataliz\u00e1torok felgyors\u00edthatja a gy\u00f3gyul\u00e1si sebess\u00e9g\u00e9t PUR, amelyek k\u00f6z\u00fcl DMDEE a legnyilv\u00e1nval\u00f3bb hat\u00e1s, 30 percen bel\u00fcl gyorsan n\u00f6velheti a ny\u00edr\u00f3szil\u00e1rds\u00e1g 14psi-r\u0151l 200psi-re, gy\u00f3gy\u00edt\u00f3 1 \u00f3ra ut\u00e1n a k\u00f6t\u00e9s szil\u00e1rds\u00e1ga el\u00e9rte a szintet k\u00e9t nap gy\u00f3gyul\u00e1s.<\/p>\n

Amellett, hogy a DMDEE a leggyorsabb gy\u00f3gyul\u00e1si sebess\u00e9ggel rendelkezik, a legjobb h\u0151t\u00e1rol\u00e1si stabilit\u00e1ssal is rendelkezik. 120 \u00b0C-os meleg\u00edt\u00e9si k\u00f6r\u00fclm\u00e9nyek k\u00f6z\u00f6tt a DMDEE PUR-rendszer \u00f3r\u00e1nk\u00e9nt mind\u00f6ssze 3,1% viszkozit\u00e1sn\u00f6veked\u00e9si sebess\u00e9get m\u00e9rt, ami mind\u00f6ssze 0,5%-tel magasabb, mint a kataliz\u00e1tormentes PUR-rendszer 2,6% n\u00f6veked\u00e9si sebess\u00e9ge. M\u00e1s kataliz\u00e1torok eset\u00e9ben a viszkozit\u00e1sn\u00f6veked\u00e9s m\u00e9rt\u00e9ke legal\u00e1bb 6,2% \u00f3r\u00e1nk\u00e9nt.<\/p>\n

Ezenk\u00edv\u00fcl, b\u00e1r a DMDEE-t nagyon kis mennyis\u00e9gben haszn\u00e1lj\u00e1k, az enyhe ingadoz\u00e1sok jelent\u0151s teljes\u00edtm\u00e9nyingadoz\u00e1sokat okozhatnak. Csak a DMDEE-tartalom 0,05%-r\u0151l 0,1%-re t\u00f6rt\u00e9n\u0151 n\u00f6vel\u00e9s\u00e9vel a 30 percig, 1 \u00f3ra \u00e9s 1,5 \u00f3ra alatt kikem\u00e9ny\u00edtett term\u00e9k ny\u00edr\u00f3szil\u00e1rds\u00e1ga hirtelen megv\u00e1ltozott.<\/p>\n

Ugyanakkor, ha gyorsan kem\u00e9nyed\u0151 PUR-t szeretne kapni, az egyik hat\u00e9kony \u00e9s azonnali m\u00f3dszer a DMDEE-tartalom 0,05%-r\u0151l 0,15%-ra t\u00f6rt\u00e9n\u0151 n\u00f6vel\u00e9se, \u00e9s 1,5 \u00f3ra alatt 290 psi ny\u00edr\u00f3szil\u00e1rds\u00e1got \u00e9rhet el, ami alapvet\u0151en megegyezik a teljesen kikem\u00e9nyedett PUR szil\u00e1rds\u00e1g\u00e1val.<\/p>\n

A t\u00fal magas DMDEE-tartalom azonban cs\u00f6kkenti a t\u00e9telek k\u00f6z\u00f6tti h\u0151stabilit\u00e1st, \u00e9s l\u00e9gbubor\u00e9kok kialakul\u00e1s\u00e1hoz vezethet a kikem\u00e9ny\u00edtett ragaszt\u00f3ban.<\/p>\n
