Lub npe tshuaj ntawm BIBP crosslinking tus neeg sawv cev yog di-tert-butylperoxyisopropylbenzene los yog di-tert-butylperoxyisopropylbenzene, nrog rau cov mis molecular C20H34O4. Nws yog cov hmoov dawb crystalline hmoov, nrog lub melting point ntawm 44 mus rau 48 degree, thiab yog ib tug dialkyl organic peroxide. Feem ntau hu ua DCP tsis muaj ntxhiab, qhov sib ntxiv yog kwv yees li 1/2 txog 2/3 ntawm DCP nyob rau hauv tib txoj kev sib txuas.
Cov ntawv thov tseem ceeb thiab kev qhia luv luv ntawm BIBP tus neeg sawv cev crosslinking yog raws li hauv qab no:
1, Styrene butadiene roj hmab kev lag luam
Styrene butadiene roj hmab (SBR) yog qhov loj tshaj plaws universal hluavtaws roj hmab ntau yam thiab ib qho ntawm cov roj hmab ntxov tshaj plaws kom ua tiav kev lag luam. Nws lub cev qauv kev ua tau zoo, kev ua haujlwm, thiab cov khoom siv kev ua haujlwm zoo ib yam li cov roj hmab ntuj. Qee yam khoom xws li hnav tsis kam, kub tsis kam, kev laus ua haujlwm, thiab vulcanization ceev yog zoo dua li cov roj hmab ntuj. Nws tuaj yeem siv ua ke nrog cov roj hmab ntuj thiab ntau yam roj hmab hluavtaws, thiab siv dav hauv kev tsim cov log tsheb, daim kab xev, roj hmab kav, xov hlau thiab cables, khoom siv kho mob, thiab ntau yam khoom siv roj hmab.
Hauv ntiaj teb kev noj cov qauv ntawm styrene butadiene roj hmab, kwv yees li 53.5% yog siv rau cov log tsheb thiab lawv cov khoom, 11.9% yog siv rau cov khoom siv roj hmab, thiab 34.6% yog siv rau lwm yam. Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob ntawm kev lag luam hauv qab dej hauv Suav teb, kev lag luam roj hmab butadiene styrene hauv Suav teb tau ua tiav qhov tseem ceeb. SBR nyob rau hauv Suav teb feem ntau yog siv rau kev tsim cov log tsheb, khau roj hmab, cov kav dej roj hmab, daim kab xev, thiab lwm yam. Ntawm lawv, cov log tsheb thiab cov khau roj hmab muaj ntau dua 70% ntawm tag nrho cov khoom siv.
BIBP crosslinking tus neeg saib xyuas feem ntau yog siv hauv kev lag luam styrene butadiene roj hmab nyiaj rau kwv yees li 15-25%, nrog rau qhov sib ntxiv ntawm 1-3%.
2, Polypropylene kev lag luam
Polypropylene (PP) yog ib qho semi crystalline thermoplastic. Nws muaj kev tiv thaiv siab, muaj zog txhua yam khoom, thiab ua haujlwm rau ntau yam organic solvents thiab acid alkali corrosion. Nws muaj ntau yam kev siv hauv kev lag luam thiab yog ib qho ntawm cov khoom siv polymer.
Cov organic peroxides siv hauv kev lag luam polypropylene fiber ntau yog dialkyl peroxides, nrog rau qhov sib ntxiv ntawm {{0}}.05-0.2%. Qhov sib ntxiv ntawm BIBP crosslinking tus neeg sawv cev feem ntau yog 0.04-0.08%, suav txog li 10% ntawm tag nrho cov tshuaj.
