Cov Ntaub Ntawv Kev Nyab Xeeb
Kev Noj Qab Haus Huv Cov phom sij: Tej zaum nws yuav raug mob yog tias nqos tau thiab yuav ua rau tawv nqaij tawv me me.
Kev phom sij ib puag ncig: nws yog qhov lom zem heev rau dej tsiaj muaj sia thiab ntev ntev.
Kev siv
As an anti - ultraviolet absorber: Methyl 2 - benzoylbenzoate can be applied to the preservation of food and beverages. Nws ua haujlwm los ntawm kev nqus cov roj choj ultraviolet rays. Qhov kev nqus no pab tiv thaiv cov khoom xyaw rau hauv cov khoom noj thiab dej haus los ntawm kev ua kom muaj zog thiab hloov pauv ntawm cov txee sib txuas.
Siv hauv UV kho: Nws yog siv dav rau UV kho cov txheej txheem thiab inks. Thaum raug rau ultraviolet teeb, nws tuaj yeem pib ua cov txheej txheem polymerization. Qhov no ua rau txheej txheej lossis cov kua mem kom sai sai rau hauv zaj duab xis. Raws li qhov tshwm sim, lub hardness, hnav tsis kam, thiab tshuaj lom neeg tiv thaiv cov khoom kawg yog txhim kho.
