3, Mɛtal Ɔksayd dɛn .
Mεtal כksid dεm na di neoprene adhesive dεm gεt fכ rol dεm: asid absכba, anti-skכch ejen, vulkanizing ejen, rεsin riaktant. As tɛm de go, neoprene rɔba go rilis trays amɔnt dɛn fɔ haydrojɛn klorayd, kin mek di polimɛr dɛn dikɔmpɔzishɔn mɔ, ɛn i go kɔrɛd mɛtal ɛn natura fayba, ad mɛtal ɔksayd dɛn kin absɔb haydrojɛn klorayd fɔ avɔyd di dɛgradishɔn kɔntinyu. di mεtal כksid dεm we dεn kin yuz jεnarali na mεntal zink כksid εn magnεsium כksid. Magnɛsiɔm ɔksayd gɛt di wok fɔ absɔb asid, prɛ-riakshɔn, anti-skɔrch, vulkanizashɔn, ɛn ɔda tin dɛn. Magnɛsiɔm ɔksayd ɛn rɛsin prɛ-riakshɔn kin impruv di adhesive ɔt rɛsistɛns ɛn protɛkt di delamination prɛsipitashɔn, magnɛsiɔm ɔksayd doz pan di prɛ-riakshɔn ifɛkt ɛn adhesive prɔpati dɛn gɛt impak, wit di magnɛsiɔm ɔksayd dos de go ɔp, di ay tɛmpracha trɛnk de go ɔp, bɔt di stebiliti fɔ di adhesive likwid de ridyus. di ad we dεn ad magnεsium כksid kin ebul fכ aksεlεrat di adhesive film fayn fayn wan to dray, εn i kin bכku bכku wan fכ bכn di fכs bon trεnk, we kin bi biכs fכ di kכlsin layt magnεsium כksid כ aktiv magnεsiכm כksid. Layt magnɛsiɔm ɔksayd na wayt amorphous pauda, we nɔ gɛt smel ɛn we nɔ gɛt teys. Rilaytiv density 3. 58, Melting Point 28520C, Boiling Point 36000C na di ays kin tek smɔl smɔl kabon dayɔgzayd ɛn wata fɔ mek dɛn gɛt di bɛsik magnɛsiɔm kabɔnɛt . Zinc oxide we dɛn ad to di kloropren adhesive kin ple wan rol fɔ absɔpshɔn fɔ asid, bɔt dat na vulkanizing ejen nɔto ɔbjɛktiv bikɔs di kloropren adhesive na mɔst ɔda tɛmpracha we dɛn de yuz di kol bikɔs ɔf di kemikal nɔ go prodyuz vulkanizashɔn, bɔt bak na di stɔrɔj fɔ di bɔt ɔf di prɛsidɛnt. di sem tεm, zink כksid kin mek di adhesive likid bi turbid, so dat di adhesive film de stika, i luk lεk se i dray nכn-dray, we dεn yuz fכ bon polyurethane fom, zink כksid go protεkt di ol we di mεtirial de ol.
