Cov Ntawv Thov
1. Roj Hmab thiab Cov log tsheb (thawj siv)
Antioxidant: DPPD tau dav siv ua antioxidant hauv kev tsim cov roj hmab thiab cov roj hmab hluavtaws, tshwj xeeb hauv cov log tsheb, thiab cov tawv ntoo, thiab hoses.
Tiv thaiv cov roj hmab los ntawm kev txiav txim siab vim:
Qho kub
Pa
Ozone
Txhim kho cov laus tsis kam thiab txuas ntxiv kev pabcuam lub neej ntawm cov khoom lag luam roj hmab.
2. Cov roj nplua nyeem ntxiv
Ua txhaum ua tus neeg tiv thaiv oxidation nyob rau hauv cov roj lubricating, tshwj xeeb tshaj yog hauv cov roj cav thiab kua dej hydraulic.
Pab tswj cov roj ruaj khov thiab ua tau zoo thaum muaj kev kub thiab tshaj.
3. Yobsics thiab polymer stabilization
Qee zaum siv hauv plastics los tiv thaiv cov polymer tsis zoo nyob rau hauv tshav kub lossis UV kis.
4. Tshuaj Nruab Nrab
Muaj nuj nqi raws li lub tsev thaiv lossis nruab nrab hauv synthesis ntawm:
Dyes
Dej pigments
Cov Tshuaj Tshwj Xeeb
Cov txiaj ntsig
1. Cov antioxidant zoo
Lub zog muaj zog rau scavenge dawb radicals thiab paintides, tseem ceeb pab txhawb cov txheej txheem oxidation hauv roj hmab thiab roj.
2. Sov thiab Ozone Kuj
Muab kev tiv thaiv zoo heev rau ob qho kev tiv thaiv zoo heev thiab ozone cracking, uas yog cov kev laus laus hauv cov ntaub ntawv elastomeric.
3. Kev Siv Sij Hawm Ntev
Txuas ntxiv lub neej ua haujlwm ntawm cov roj hmab-raws cov khoom lag luam thiab roj nplua nyeem thiab cov roj roj hauv qab yam teeb meem ib puag ncig.
4. Kev sib raug zoo
Tau tshaj cov roj hmab ntau hom, suav nrog:
Natural Roj Hmab (NR)
Styrene-Butadiene roj hmab (SBR)
Nitrile Roj Hmab (NBR)
Butadiene roj hmab (br)
Tag
N, n-diphenyl-1,4-phenylenediamine (DPPD) yog tus neeg sawv cev muaj zog thiab tiv thaiv cov roj hmab feem ntau yog hauv kev lag luam roj hmab thiab roj nplua nyeem. Nws lub peev xwm los tswj kev kub taub hau, oxygen, thiab ozone ua rau nws tseem ceeb heev ntawm cov ntaub ntawv muaj kev lag luam, cov log tsheb tshwj xeeb yog thiab elastomicies cov xwm txheej nthuav tawm.
Qhia rau kuv paub yog tias koj xav tau qhov no hauv hom ntawv lossis xav tau SDS / txwv kev ua raws cov ntsiab lus (piv txwv li, mus txog, tsCA).
