1. Botelemeli ya molunge .
Bokóli ya thermal ya caoutchouc ezali lolenge moko ya bobange ya oxidatif oyo euti na ba radicaux libres.Mpo na biloko oyo esengeli na résistance ya molunge makasi, pona diphénylamine mpe TMDQ mpe ba agents anti-âges mosusu oyo ekoki kozala na molunge te.En plus, résistance ya molunge ya malamu koleka ekoki kozwama na kosangisa ba bloqueurs oyo ya ba radicaux libres na ba agents ya décomposition ya peroxyde lokola MBBI{3}}
2. Botelemeli ya bopanzani ya flexion .
Fissures flexibles ezali résultat ya vieillissement oxidatif ya surface ya produit oyo ewutaka na réaction ya ba radicaux libres.Po na kopekisa forme oyo ya vieillissement, pona ya amine to ba antiozonants phénoliques (ba inhibiteurs radicaux libres) e jouaka rôle.Effet ya mobilité ya surface ya munene ezali excellent.
3. Botelemeli ya ozone .
Antiozonants include p-phenylene diamines, TMDQ, sulfur veins and protective waxes, etc. Generally, the combination of the contaminated p-phenylene diamines with the non-contaminated sulfur veins and paraffin can achieve excellent results.However, the sulfur vein compounds have a significant tendency to accelerate scorch.In addition, ozone Bobange esalemi na likolo ya biloko, yango wana effet ya ba agents anti-ozonation na mobilité ya likolo ya monene ezali excellent.Ya kala, ba ozonants ya poids moléculaire ya likolo esalemi mpo na kokoba kosalela.Copyright Caoutchouc Information Net .
4. Botelemeli na bobange ya bibende ya mabe .
Ba agents ya vieillissement anti - métal oyo ezali mabe ekoki kokabolama na ba agents ya scellage ya ion ya métal mpe ba agents inertes ya surface ya métal.Oyo ezali na ba effets excellents ya ba p-phénylènediamines mpe ba composés bisphénol, oyo ya suka ezali na ba composés mercaptan (lokola MB anti-âge) mpe ba composés ya trilata.Antrais administratifs elongo na ba agents oyo ezali na ba agents ya mabe, oyo ezali na ba agents ya mabe, oyo ezali na ba agents ya mabe, oyo ezali na ba agents oyo ezali na ba agents oyo ezali na ba agents oyo ezali na ba agents oyo ezali na ba agents oyo ezali na ba agents oyo ezali na ba agents oyo bazali na ba agents ya mabe, na kati ya ba agents oyo ezali na ba agents oyo bazali na likama, oyo ezali na ba agents oyo ezali na ba agents oyo ezali na likama, oyo ezali na ba agents oyo ezali na ba agents oyo ezali na likama, Ba agents. .
5. Kobukana ya anti-lumière mpe konuna .
Carbon black is an excellent ultraviolet absorber.Therefore, anti-aging agent for carbon black is not necessary, and for light products (carbon black is only used as a colorant) it is indispensable.For anti - aging with the general use of the first anti - aging agent and the second anti - aging agent.Among the antiaging agents, phenylenediamine antiaging agents have excellent anti-photoaging effect, but there is serious pollution.Among the non-polluting anti-aging agents, phenols, blocked amines and paraffin wax have excellent effects.In phenolic antioxidant, antiager DTBM P (2, 6 two tertiary butyl 4 methyl phenol) and stabilizer sP styrene (phenol) and stabilizer MBMTB [2, 2 '- methylene Double (4 méthyl 6 moko tertiaire butyl phénol)] mpe antiager mbetb [2, 2 gaz méthylène double (4 a éthyl, 6 tertiaire butyl phénol)] Résistance ya fissures ya lumière ya effet ezali excellent.
6. Pona cire ya paraffine .
After vulcanization, paraffin wax is ejected on the surface of the product to form a physical protective film and effectively prevent ozone cracking of the product.The conditions in which paraffin is ejected on the surface of the product vary according to its composition, the type of rubber used (rubber and additives), and the temperature.Therefore, it is very important to choose paraffin wax that meets the conditions of use.
