Soufre, minerais commun na nature, ezali na valeur médicale ya motuya mingi.Kasi na miso ya bato ya caoutchouc, soufre ekoki kozala na usage ya ntina mingi koleka kisi - biloko ya caoutchouc na agent vulcanisation.ebandeli ya soufre mpe caoutchouc ezongaka na Charles Goodyear, "tata ya caoutchouc".
Association historique ya caoutchouc na soufre .
Lokola eloko ya kala, caoutchouc esalelamaki na bankoko na biso kala mingi te. Na ntango wana, caoutchouc ezalaki mingi mingi kosalelama mpo na ba adhésifs mpe bilamba oyo ekoki kokɔta na mai.Flaw ya liwa ya caoutchouc ezali ete ezali na sensibilisation mingi na température.température ezali mwa likolo yango ekokoma pete mpe ya kokangama{ mpe ya makasi ya moke na température ya makasi;
Na eleko ya molunge ya 1834, Goodyear ayaki kotala société ya caoutchouc indien na New York. ayebaki ete propriété oyo ya caoutchouc etungisaki industrie mobimba ya caoutchouc, kasi caoutchouc ezalaki mpe na série ya ba propriétés excellentes lokola élasticité ya likolo, plasticité, durability, imperméable mpe isolation. Yango wana, Goodyear ezalaki déterminé ya koyekola modification ya caoutchouc{33} na kati ya 1839 1839 1839 1839 1839 1839 1839 1839 1839 1839 1839 Substance lokola cuir.Matériel oyo epanzani te na température ya likolo ndenge eyebani mingi mpo na caoutchouc élastomérique.Nsima ya série ya ba modifications, Goodyear ekomaki convaincu que produit na ye eko décomposer te na température moko na se ya point d’ébullition.Bongo ezalaki découverte intentionnelle oyo na Goodyear{}. Contribution na industrie ya caoutchouc américain, Frank.Mr Coughlin apesaki kombo ya compagnie na ye ya pneu na caoutchouc Goodyear mpe azali sikoyo moko ya ba tyremakers misato ya liboso ya mokili mobimba.
Bokaboli ya soufre .
Soufre oyo esalelami na industrie ya caoutchouc ezali na poudre ya soufre, soufre insoluble, soufre colloïdal, soufre précipité, soufre sublimé, soufre décidifié mpe soufre non cristalline.Misato ya liboso esalelamaka mingi.
Poudre ya soufre: Ezali soufre oyo esalelamaka mingi na industrie ya caoutchouc.
Soufre insoluble: Homopolymère ya soufre, oyo eyebani mpe na kombo ya soufre polymérisé.Litomba na yango ya monene ezali ete biloko yango ezali pete te mpo na kosopela malili, esalelamaka mingi na biloko ya caoutchouc ya grade ya likolo lokola pneu radial ya bibende.
Soufre colloïdal: Pâte oyo esalemi na konika poudre ya soufre to soufre ya ko se régler na dispersant.Mikanda oyo basalelaka pona ba produits ya latex.
Role ya soufre na ba produits ya caoutchouc .
In order to obtain good performance of traditional rubber, linear macromolecular chains must be cross-linked to form a three-dimensional network structure.The crosslinking process is often referred to as vulcanization of rubber because the original crosslinking was done with sulfur.Rubber after vulcanization, with the change of structure, properties have changed: rubber no longer flow when heated, no longer dissolved in its good solvent, modulus and hardness, mechanical Ba propriétés, résistance ya vieillissement mpe stabilité chimique ebongisamaki.Yango wana, kaka sima ya bokutani ya soufre, caoutchouc ekomi performance ya malamu, ba matériaux polymères oyo esalemi mingi.
Ya solo, bokeli ya soufre na réseau ya vulcanisation ya caoutchouc esengi mpe kobakisa ba agents actifs, ba promoteurs mpe ba additifs mosusu mpo na kosala système ya vulcanisation ya mobimba, mpe na bokeli ya industrie ya caoutchouc, bato batiaka liboso masengi ya likolo mpo na bosali ya biloko ya caoutchouc, na yango, mitindo ya soufre mpe ba substituts ezali mpe mokemoke kosalama mpe kobimisama.
