DHBP 101, tshuaj lub npe 2,5-Dimethyl-2,5-di (tert-butylperoxy) hexane, molecular mis C16H34O4, yog ib qho tsis muaj hluav taws xob, me ntsis daj pob tshab kua, thiab yog dialkyl organic peroxide. DHBP 101 feem ntau yog siv los ua cov txheej txheem polymerization, nrog rau tus kheej accelerating decomposition kub (SADT) ntawm 80 degree. Nws tuaj yeem diluted nrog hexane, odorless ntxhia roj, isododecane, thiab lwm yam. Xwb, nws tuaj yeem diluted nrog cov neeg siv khoom hnyav. Inorganic compounds los yog polypropylene hmoov kuj tseem siv tau rau desensitization.
Cov cheeb tsam tseem ceeb ntawm DHBP 101 (kab lus no yog qhov thib ob) thiab nws cov lus qhia yog raws li hauv qab no:
1, Kub vulcanized silicone roj hmab kev lag luam
Nyob rau hauv xyoo tas los no, fluorosilicone roj hmab, uas tau dhau los ua ib lub ntsiab lus tshawb fawb nrov hauv thaj chaw ntawm cov organic silicon, muaj kev cia siab dav. fluorosilicone roj hmab yog cov khoom siv polymer nrog - Si O - ua cov qauv saw tseem ceeb. Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias dua li cov roj hmab fluorosilicone, cov roj zoo dua thiab cov tshuaj tiv thaiv zoo dua li cov roj hmab silicone, thiab tam sim no yog cov roj hmab zoo tshaj plaws ntawm cov roj hmab tshwj xeeb. Nws tuaj yeem siv rau hauv thaj chaw xws li aerospace, aircraft, tsheb, petrochemicals, machinery, khoom siv hauv nruab nrog cev, thiab lwm yam. Txawm li cas los xij, vim tias tam sim no tus nqi ntawm fluorosilicone roj hmab tau ntau dua li silicone roj hmab thiab fluorosilicon roj hmab, nws siv hauv kev lag luam pej xeem yog tseem me me, thiab nws yog tam sim no tsuas yog siv hauv kev lag luam tub rog.
Cov hom tseem ceeb siv hauv kev lag luam kub vulcanized silicone roj hmab yog 2, 5-Dimethyl-2, 5-di (tert-butylperoxy) hexane (tseem hu ua DHBP 101), Di-tert- butyl peroxide (DTBP), 1, 1-Di-(tert-butylperoxy) -3, 3, 5-trimethylcyclohexane (TMCH), thiab Di (2, 4- chlorobenzoyl) peroxide (DCBP).
Ntawm lawv, 2, 5-Dimethyl-2, 5-di (tert-butylperoxy) hexane (tseem hu ua DHBP 101) yog siv rau molding vulcanization, accounting rau kwv yees li 40% ntawm tag nrho cov nyiaj, nrog rau qhov sib ntxiv ntawm 0.8 mus rau 2%.
2, Ethylene propylene roj hmab kev lag luam
Ethylene propylene roj hmab feem ntau yog siv hauv kev lag luam xws li tsheb, kev tsim kho, roj additives, thiab cov xov hlau thiab cables, nrog rau qhov sib txawv ntawm cov qauv siv ntawm cov teb chaws thiab cheeb tsam: kwv yees li 60% -70% ntawm ethylene propylene roj hmab noj hauv United. Lub xeev yog nyob rau hauv daim teb ntawm cov khoom ruaj khov; Txog 56% ntawm Western Europe yog siv hauv kev lag luam tsheb, suav nrog cov ntawv thov ncaj qha lossis polymer hloov kho; Txog 70% ntawm Nyiv cov ethylene propylene roj hmab yog siv nyob rau hauv kev lag luam automotive, thaum nyob rau hauv Tuam Tshoj, ethylene propylene roj hmab yog tsuas yog siv nyob rau hauv kev lag luam automotive, yas runways, polymer modification, waterproof yob, thiab nyob ntawm tej thiab cables. Kev siv ethylene propylene roj hmab hauv Suav teb yog nyob rau theem kev loj hlob thiab muaj kev loj hlob dav dav. Txawm li cas los xij, tam sim no, lub peev xwm ntau lawm ntawm ethylene propylene roj hmab cov lag luam hauv Suav teb yog me me, thiab cov khoom lag luam ntawm lub xeev cov khoom muaj tsawg, uas tsis tuaj yeem ua tau raws li kev lag luam loj.
Cov hom tseem ceeb ntawm cov organic peroxides siv hauv kev lag luam ethylene propylene roj hmab muaj xws li 2, 5-Dimethyl-2, 5-di (tert-butylperoxy) hexane (tseem hu ua DHBP 101), Di- tert-butyl peroxide (DTBP), 1, 1-Di-(tert-butylperoxy)-3,3,5-trimethylcyclohexane (TMCH), thiab 1,1-Di( tert-butylperoxy) cyclohexane (CH). Ntawm lawv, 2,5-Dimethyl-2,5-di (tert-butylperoxy) hexane (tseem hu ua DHBP 101) suav txog 10%; Qhov sib ntxiv yog nyob ib ncig ntawm 2%.
