Daim ntawv thov ntawm 1,3-dimethyl6-aminouracil
(1) 1,3-dimethyl-6-aminouracil thiab zinc stearate
Thaum 1,3-dimethyl6-aminouracil siv nrog ua ke nrog zinc stearate, nws tuaj yeem hnov mob nrog ZnCl2 ua los ntawm zinc stearate los ua cov hlau ua cov nyom, uas ua rau ZnCl2 tsis siv zog, zoo tiv thaiv" zinc hlawv" thiab txhim kho kev ruaj ntseg mus sij hawm ntev ntawm PVC khoom. Piv nrog rau DBM, uracil tsis muaj xim tsis haum, tsis muaj qab, zoo li thawj xim thiab lub hom phiaj ntev ntev.
(2) 1,3-dimethyl6-aminouracil thiab hydrotalcite
Nws yog siv nrog hydrotalcite. Hauv cov qauv ntawm calcium zinc stabilizer, ntxiv 3-4 % 1,3-dimethyl6-aminouridine thiab 8-10 % hydrotalcite tuaj yeem cuam tshuam zoo dua qhov pib xim ntawm PVC, thiab cov mis ntau dua kev lag luam thiab txhim khu kev qha. Cov kws tshaj lij tau soj ntsuam cov txiaj ntsig thermal stability ntawm 1,3-dimethyl6-aminouracil thiab hydrotalcite li 1 + 1 = 3.
(3) 1,3-dimethyl6-aminouracil thiab β - Dione
Piv nrog β - diketone, lawv yog cov tshiab stabilizers. Piv nrog rau ob, 1,3-dimethyl6-aminouracil tuaj yeem ua tau zoo dua hauv kev thas xim tha xim thaum pib thiab kev ua haujlwm ntev hauv thermal. Hauv cov txheej txheem ntau lawm, 1,3-dimethyl6-aminouracil tuaj yeem hloov β - diketone tag nrho, thiab tuaj yeem siv nrog β - diketone.
(4) Cov mis ib hom ntawm 1,3-dimethyl6-aminouracil yog cov tshuaj tiv thaiv lub ntsiab
1,3-dimethyl6-aminouracil 1-5 ntu
10-100 qhov chaw ntawm epoxy kua roj
Calcium stearate 3-10 qhov chaw
Zinc stearate 3-10 qhov chaw
Organic ntxiv 2-15 qhov chaw
Ntawm lawv, organic additives suav nrog:
Sodium perchlorate 1-10 ntu
Triphosphate 1-5 qhov chaw
(5) Kev saib ib puag ncig
Uracil, pawg tseem ceeb ntawm 1,3-dimethyl6-aminouracil, yog ib ntawm plaub lub nucleotides uas tsim nyog rau tib neeg lub cev. Nws tuaj yeem nqus HCl tsim nyob rau hauv PVC cov txheej txheem ntau lawm, thiab tuaj yeem hloov cov tshuaj chlorine atoms tsis ruaj khov kom tiv thaiv kom tsis txhob muaj dej ntau ntxiv. Qhov ntsuas daj ntawm stabilizer muaj 2-4 ntu ntawm 1,3-dimethyl6-aminouracil poob qis dua 40% nyob rau hauv tib cov xwm txheej piv nrog cov khoom tsis muaj.
