Daim ntawv thov

1. Tshuaj pleev ib ce

Sunscreen muaj nuj nqi: 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 yog ib qho zoo heev ultraviolet absorber, uas tuaj yeem nqus tau 260-340 nanometers ntawm ultraviolet lub teeb, tshwj xeeb tshaj yog UVB band, tab sis kuj nqus ib feem ntawm UVA band, uas tuaj yeem thaiv qhov kev puas tsuaj ntawm daim tawv nqaij, tiv thaiv tshav ntuj, tshav ntuj, tshav ntuj, tshav ntuj. thiab lwm yam, feem ntau ntxiv rau cov tshuaj pleev thaiv hnub, moisturizing sunscreen dej thiab lwm yam khoom.

Txhim kho qhov ruaj khov ntawm cov mis: nrog cov dej zoo solubility, durability, dispersion, tsis tshua muaj kev tsiv teb tsaws, zoo thermal stability, muaj peev xwm ua kom cov kev ntxhib los mos ntawm cov tshuaj pleev thaiv hnub thiab lwm yam khoom tshiab, tab sis kuj inhibit qhov decomposition ntawm lwm cov tshuaj tiv thaiv UVB, pab txhim kho kev ruaj ntseg ntawm cov tshuaj pleev ib ce mis thiab durability ntawm cov tshuaj pleev thaiv hnub.

2. Xim teb:2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 tuaj yeem siv los ua ultraviolet absorber ntawm cov xim dej, uas tuaj yeem nqus tau lub teeb ultraviolet, txo qhov kev puas tsuaj ntawm lub teeb ultraviolet rau cov xim, txhim kho huab cua thiab kev pabcuam lub neej ntawm cov xim, tiv thaiv cov xim los ntawm fading, chalking, tawg thiab lwm yam teeb meem zoo li, yog li nws muaj peev xwm ua tau zoo ntawm cov xim.

3. Cov khoom siv tshuaj:2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 yog siv los tsim cov khoom siv hluav taws xob sab nraum zoov nrog cov huab cua tiv thaiv thiab oxidation tsis kam, uas tuaj yeem nqus tau ultraviolet rays, txo cov kev laus ntawm ultraviolet rays ntawm cov ntaub ntawv cable, thiab txhim kho cov kev pab cuam lub neej thiab kev ua haujlwm ntawm cov cables.

4. Bionic sensor teb:2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 tuaj yeem siv los tsim bionic sensors rau kev txiav txim siab ntawm 4-methylbenzyl camphor (4-MBC).

5. Roj teb:2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 tuaj yeem hloov pauv nucleophilic nrog kua bromine los npaj brominated 2-phenylbenzimidazole-5-sulfonic acid, thiab tom qab ntawd hnov mob nrog cov amino pawg ntawm 3,4,4 '-triamino-diphenyl ether rau cov khoom sib cuam tshuam nrog rau cov khoom lag luam ntxiv, thiab tom qab ntawd ua rau cov khoom lag luam sib cuam tshuam. polyurea thickener rau kev npaj polyurea roj.

6. Lwm qhov chaw:Nws tuaj yeem siv los ua kev tshuaj ntsuam reagent rau kev tshawb fawb kev sim, thiab tseem tuaj yeem siv rau hauv kev npaj cov ntaub ntawv supramolecular intercalation structural. Cov khoom tom qab intercalation yuav siv tau los ua ib qho zoo heev ultraviolet absorber los txhim kho cov kev laus tiv thaiv ultraviolet muaj peev xwm ntawm cov ntaub ntawv sib xyaw.
