, 1. butadiene rubber
Butadiene rubber is commonly known as cis-rich butadiene rubber, butadiene rubber as raw material, by nickel naphthenate as catalyst, synthesis, generated by solution polymerization is industrialized earlier, mature technology of general synthetic rubber varieties, and has excellent abrasion resistance, good flexing resistance, high resilience, small hysteresis loss, low heat, good low temperature performance characteres; late usus est in fabricare de Tyri calcantium, latus Tyro corpus, etiam in fabricantium Flexilis tape, Flexilis caligarum et alia industriae, infectum est, sed habet bonum, frigus raw {I}}
Structura rara terra Butadiene Flexilis contentus est altior, angusto molecular pondus distribution, non continent ramosis et gel, ergo habet resistentia, adsume resistentia, ut in artificiis, in strigare et ad reducere ad bigas, in quodammodo ad redigendum est in armore, in quodammodo potest reducere, in eodem tempore ad redigendum est in fabricantibus, in quodammodo potest reduci Tyio gerunt {.
Rare Terra Butadiene Flexilis Catalytic Ratio
Secundum ad catalytic system, in technologies usus est a mundo shunding Flexilis productio turmas potest dividitur in quinque major systems: Nickel in Elimination Titanium, et Cobaltus Ratio est maxime propter productionem, impact polystyrene modification for the nickel butadiene is our country in the 1960 s the successful development of highly active nickel catalysts, respectively in 1965 in jinzhou, lanzhou, began to industrialized production, butadiene rubber production of new technological achievements in 1985, special-class award of national scientific and technological progress, after half a century of several generations efforts, China's nickel Productio Technology et Nickel Butadiene Product Quality in mundo Advanced Level {{V}}
De Nickel Catalytic ratio:
{1. Nickel catalytic system est a multicompent ratio {{I}} et dosis Ratio, pascens modus et senescentis modus catalysts non solum afficit actione et catalyticum, sed etiam afficit, sed etiam afficit in pondus polymer {II}
II, Nickel Catalyst system stabilitatem, polymerization temperatus, ut aptet ad amplis, in reactionem temperatus super CXX gradus, quod ratio tamen non inactivation, habet bonum temperatus, {{II}}
{3. et Nickel catalytic system habet bonum directivity et minus affectus est moles catalyst et concentration monomar {{I}}
, 4. et Nickel Catalyzed ratio fecit a numerus of torquem translationem Butadiene per polymerization processus, ducens ad torquem termination {I}}
Polymerization characteres rara terra catalytic systematis:
{1. Saturared Hydrocarbon Hexane est usus ut solvendo, quod est conducere ad environmental praesidium;
, 2. princeps monomar conversionem rate, etiam perveniens C%;
, 3. Non est facile ad producendum crucem-vinculum reactionem et generate gel {{II}}
Proprietatibus rara terra butadiene rubber
Et Butadiene Flexilis produci per rara terra catalysis ratio habet altiorem mocecular torquem regularitatem et excelsis Moneoney Viscosity, significans quod est Molecular torquem habet quoddam quantitatem longum torquem,., quod est in Rare
By comparison, the rare earth catalyzed polymerization of butadiene rubber has a high cis structure, less branched, no gel, so it has a good linear structure, known as high dimensional regularity of butadiene rubber.It can produce strong crystallization under the action of stretching, that is, with "stress crystallization ability, which gives rare earth butadiene rubber high self-viscosity, good Tensile proprietatibus et commoda abrasion resistentia et lassitudine resistentia, ut primum Flexilis ad armigens artifice de summus perficientur coronas {III}}
Development flecte de rara terra butadiene Flexilis
Japan synthetic rubber company research found that rare earth rubber is the future development trend.Rare earth glue in line with the high performance tire in high speed, safety, energy saving, environmental protection, etc, is now the fastest-growing BR varieties, with the European and American countries tire aspects and so on energy conservation and environmental protection, safety technical regulations require stricter, products for export-oriented enterprises and Technical claustra, domesticis resource discrimine et environmental pollutio est imminenti, industria consolatione encourages in progressionem viridi strigare et in itinere, et paulatim adscribere industria technology et in aucupibus et in productum, aliae domestica et emendationem et in aucupatos et in productione et in Austriene Butadiene Flexilis, Rare Terrae, Butadiene Flexilis vel solum electio productio conatibus {{III}}
