Triallyl isocyanurate (TAIC) yog ib qho heterocyclic compound uas muaj peb daim ntawv cog lus ob npaug. Nws yog feem ntau siv los ua tus neeg sawv cev crosslinking, vulcanizing pab, thiab hluav taws xob sensitizer hauv kev lag luam, thiab yog siv dav hauv roj hmab vulcanization, yas crosslinking, cov khoom siv sib xyaw, thiab lwm yam. Nws lub luag haujlwm tseem ceeb yog tsim peb tus qauv - qhov sib txuas network los ntawm kev sib txuas ntxiv ntawm ob daim ntawv cog lus, kev txhim kho cov khoom siv hluav taws xob, kev siv lub zog, thiab kev laus ua haujlwm.
Kub kub ntau rau siv nyob rau hauv ntau daim ntawv thov scenarios
Qhov kub thiab txias rau kev siv TAIC tsis yog tus nqi ruaj khov thiab yuav tsum tau txiav txim siab raws li cov kev thov tshwj xeeb thiab kev siv tshuab ua haujlwm. Cov hauv qab no yog qhov kub thiab txias rau cov xwm txheej ib txwm:
1. Roj hmab vulcanization system
Liquid TAIC feem ntau ua ke nrog peroxides (xws li DCP, BPO) raws li vulcanization system, haum rau cov roj hmab ntuj (NR), styrene butadiene roj hmab (SBR), ethylene propylene diene monomer (EPDM), thiab lwm yam.
-Sulfurization kub: feem ntau ntawm 140℃thiab 180℃. Piv txwv li, thaum EPDM roj hmab ua ke nrog DCP (diisopropylbenzene peroxide) thiab TAIC, qhov vulcanization kub feem ntau yog xaiv ntawm 160 ° C thiab 170 ° C. Ntawm qhov kub no, ib nrab - lub neej ntawm DCP yog li ntawm 1 feeb, thiab allyl ob daim ntawv cog lus ntawm TAIC sai crosslinks nrog cov roj hmab sib txuas; Yog tias qhov ntsuas kub qis dua 140 degree, cov tshuaj tiv thaiv tus nqi qeeb dhau thiab qhov kev sib txuas ntawm kev sib txuas yog tsawg; Tshaj 180 degree, nws tuaj yeem ua rau TAIC decomposition (decomposition kub yog li 220 degree, tab sis kub siab tuaj yeem ua rau muaj kev cuam tshuam sab nraud) lossis roj hmab degradation.
-Kev zam: Hauv qis- kub vulcanization tshuab (xws li qee cov roj hmab tshwj xeeb), los ntawm kev xaiv cov peroxides uas tsis tshua muaj decomposition kub (xws li TBHP), kev ua haujlwm kub ntawm TAIC tuaj yeem txo mus rau 120℃~ 140℃.
2. Yas ntoo khaub lig-txuas teb
Liquid TAIC yog siv rau crosslinking kev hloov pauv ntawm cov yas xws li PVC, PE, PP, thiab lwm yam, los txhim kho cov khoom siv hluav taws xob thiab kev nkag siab:
-PVC cross-kev sib txuas: Thaum tsim cov ntoo khaub lig- txuas PVC cov ntaub ntawv txuas nrog peroxides, kev ua haujlwm kub ntawm 160℃txog 190℃. Ntawm qhov kub no, PVC melts tag nrho, thiab TAIC thiab peroxide ua hauj lwm ua ke los tsim ib tug ntoo khaub lig- txuas cov qauv, ua rau lub sij hawm ntev - siv kub ntawm cov ntaub ntawv cable los ntawm 70℃mus rau ntau tshaj 90℃.
-PE irradiation crosslinking: TAIC ua hauj lwm raws li hluav taws xob rhiab heev, thiab cov txheej txheem irradiation kub feem ntau nyob nruab nrab ntawm chav tsev kub thiab 80℃(kom tsis txhob PE melting thiab deformation). Tom qab irradiation, kev kho cua sov ntawm 100℃mus rau 120℃yog xav tau los txhawb cov tshuaj tiv thaiv ntawm ob daim ntawv cog lus ntxiv thiab ua tiav crosslinking.
3. Cov khoom siv sib xyaw ua ke
Hauv iav fiber ntau reinforced yas (FRP) los yog cov khoom siv sib xyaw ua ke, TAIC ua tus neeg sawv cev sib txuas ua ke nrog cov khoom siv tsis zoo polyester:
-Curing kub: feem ntau ntawm 80℃thiab 150℃. Piv txwv li, nyob rau hauv tes nteg txheej txheem molding, TAIC tuaj yeem ceev cov resin crosslinking thaum kho ntawm chav tsev kub (25℃~ 40 degree); Thaum lub sij hawm compression molding, qhov kub yog nce mus rau 120℃~ 150℃kom luv lub sij hawm kho thiab txhim kho cov khoom siv ntawm cov khoom sib xyaw.
Qhov kub ntau rau kev siv tus neeg sawv cev crosslinking TAIC nws txawv nyob ntawm qhov kev thov scenario, nrog rau qhov tseem ceeb ntawm 120℃~ 190 degree: roj hmab vulcanization feem ntau yog nyob nruab nrab ntawm 140℃~ 180 degree, yas crosslinking yog nyob nruab nrab ntawm 160℃~ 190 degree, thiab cov khoom sib xyaw curing yog nruab nrab ntawm 80 . Kev tswj qhov kub thiab txias yuav tsum tau ua ke nrog cov kab sib txuas sib txuas, cov yam ntxwv ntawm cov txheej txheem substrate, thiab cov txheej txheem yuav tsum tau ua, thaum tswj kev ruaj ntseg ntawm 0℃~ 30℃thaum khaws cia. Kev xaiv qhov kub thiab txias tsim nyog yog tus yuam sij rau kev ua kom pom kev sib txuas ntawm TAIC thiab txhim kho cov khoom siv.
