Nta & Qhov Zoo
Primary Monomer rau Synthetic Natural Rubber
Muaj peev xwm ua tau polymerized los tsim cov hluavtaws cis-1,4-polyisoprene (IR), uas zoo sib xws cov qauv thiab cov khoom ntawm cov roj hmab ntuj (Hevea roj hmab).
Versatile Building Block
Ua haujlwm tseem ceeb monomer rau tsev neeg ntawm hluavtaws elastomers, suav nrog styrene-isoprene-styrene (SIS) thaiv cov copolymer rau cov nplaum thiab isoprene-isobutylene roj hmab (IIR/butyl roj hmab).
High Purity rau Optimal Polymerization
Polymer-qib kua isoprene nrog cov impurities tsawg ua kom muaj txiaj ntsig catalyst kev ua tau zoo, tswj qhov hnyav molecular, thiab cov khoom siv polymer zoo ib yam hauv Ziegler-Natta, anionic, lossis lwm yam txheej txheem polymerization.
Strategic Raw Khoom
Muab qhov ruaj khov, tuaj yeem hloov tau, thiab ua tau zoo - tswj lwm txoj hauv kev los yog ntxiv rau cov roj hmab ntuj, txo cov saw hlau volatility.
Cov yam ntxwv ua haujlwm
Cov kua isoprene (99.50%) feem ntau yog siv los ua ib qho reactive diene monomer. Nws conjugated ob daim ntawv cog lus tso cai rau nws koom nrog ntau yam saw - loj hlob polymerization tshwm sim. Raws li kev ua ntawm cov catalysts tshwj xeeb (xws li, Ziegler-Natta catalysts, lithium-raws li catalysts), isoprene tuaj yeem polymerize los ua polyisoprene nrog microstructure tswj tau (cis-1,4, trans-1,4, lossis 3,4 ntxiv). Qhov kev tswj ntawm microstructure ncaj qha txiav txim siab elastic zog ntawm cov polymer kawg. Nws kuj tseem tuaj yeem copolymerize nrog monomers xws li styrene los ua cov thermoplastic elastomers. Vim nws cov reactivity siab, ruaj khov kua isoprene yuav tsum tau ua tib zoo saib xyuas, thiab inhibitors feem ntau yuav tsum tau muab tshem tawm ua ntej polymerization (xws li, los ntawm alkaline ntxuav).
Thawj daim ntawv thov teb
Synthetic Rubber Production
Kev siv tseem ceeb yog hauv kev tsim cov roj hmab hluavtaws polyisoprene (IR) rau cov ntawv thov uas xav tau siab purity thiab sib xws, xws li hnab looj tes phais, lub raj mis, thiab siab - cov khoom siv log tsheb ua haujlwm.
