5.s cov ntsev, sodium ntsev thiab zinc ntsev tuaj yeem siv los ua cov stabilizer ntawm PVC.
6.Nws tuaj yeem siv ua antioxidant hauv kev txiav cov kua hlau ua kua, tus neeg sawv cev tiv thaiv tus neeg tiv thaiv antin.
Nws yog soluble hauv dej cawv thiab benzene, insoluble hauv dej.
Khaws rau hauv qhov chaw txias, tshuab ua kom muaj zog. Tseg deb ntawm hluav taws thiab cov khoom cua sov. yuav tsum tau cia kom deb ntawm oxidizer, tsis txhob khaws cia ua ke. Thaj chaw cia yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov to. Yuav tsum muab cia rau hauv qhov chaw txias, qhuav, khaws lub thawv kaw kom nruj. Cia kom deb ntawm cov muaj zog oxidants thiab cov hauv paus muaj zog. * Peb tuaj yeem muab cov tsheb thauj khoom sib txawv raws li cov neeg siv 'xav tau.
* Thaum qhov ntau yog me me, peb tuaj yeem xa khoom los ntawm cov huab cua lossis thoob ntiaj teb, aws, orgs thiab ntau yam ntawm thoob ntiaj teb thauj cov kab tshwj xeeb.
* Thaum muaj nuj nqis yog loj, peb tuaj yeem xa nkoj los ntawm hiav txwv los xaiv chaw nres nkoj.
* Dhau li, peb kuj tuaj yeem muab cov kev pabcuam tshwj xeeb raws li cov neeg siv khoom siv 'kev xav tau thiab cov khoom lag luam.
Thaum thauj 4-tert-butylbenzoic acid, nws yog ib qho tseem ceeb kom xav txog kev ceev faj hauv qab no thiab cov lus qhia:
1. Ua raws li kev ua raws li: Ua kom ua raws li cov kev cai hauv zos, hauv tebchaws thiab thoob ntiaj teb hais txog kev thauj cov tshuaj. Qhov no suav nrog kev faib tawm ua haujlwm, sau npe thiab cov ntaub ntawv.
2. Ntim: Siv cov ntaub ntawv ntim uas tsim nyog uas tsim nyog nrog cov tshuaj. Feem ntau, qhov no cuam tshuam siv cov thawv ruaj khov uas tsis tau muaj feem ntau tawg thiab xau dej. Nco ntsoov tias lub thawv ntim kaw kom nruj.
3. Sau npe: Sau npe kom meej meej daim ntawv nrog lub npe tshuaj lom neeg, cim kev phom sij, thiab cov ntaub ntawv muaj kev phom sij. Qhov no suav nrog cov ntaub ntawv tiv toj thaum muaj xwm ceev.
4. Kev tswj kub: Yog tias tsim nyog, kev tswj kom ntsuas kub thaum thauj mus los tiv thaiv kev ua kom sov siab uas tuaj yeem cuam tshuam rau qhov sib txuas ntawm cov compound.
5. Zam cov khoom siv tsis sib xws: kom paub tias 4-tert-butylbenzoic acid tsis tau xa ua ke nrog cov khoom siv tsis sib xws xws li cov tshuaj oxidants muaj zog lossis hauv qab.
6. Cov Ntawv Teev Tseg Kev Nyab Xeeb (SDS): Sau ib daim qauv ntawm cov ntaub ntawv kev nyab xeeb nrog koj cov zaub mov xa tuaj los muab cov ntaub ntawv ntawm kev phom sij, tuav, thiab ntsuas xwm ceev.
7. Kev kawm: Ua kom cov neeg ua haujlwm tau koom nrog hauv kev thauj mus los hauv kev thauj mus los kom daws cov txheej txheem txaus ntshai thiab nkag siab cov txheej txheem kom raug rau kev thauj cov khoom siv.
