Khoom Taw Qhia
Methyl 4-hydroxybenzoate, tseem hu ua Methyl Paraben, feem ntau yog siv los ua cov tshuaj tua kab mob rau cov organic synthesis, zaub mov, tshuaj pleev ib ce, tshuaj, thiab tseem siv los ua khoom noj khoom haus.
Methyl 4-hydroxybenzoate yog cov organic teeb meem. Vim nws cov qauv phenolic hydroxyl, nws muaj cov kab mob tua kab mob zoo dua li benzoic acid thiab sorbic acid. Cov kev ua ntawm paraben feem ntau yog vim nws lub xeev molecular, thiab pawg hydroxyl hauv molecule tau esterified thiab tsis ionized lawm. Yog li ntawd, nws muaj txiaj ntsig zoo nyob rau hauv thaj tsam ntawm pH 3 txog 8. Nws yog ib qho tshuaj inert thiab yooj yim rau kev sib xyaw nrog ntau yam tshuaj lom neeg.
Khoom Feature
1. Kev ua haujlwm ruaj khov;
2.Nws yuav tsis muaj decomposition lossis kev hloov pauv hauv qhov kub thiab txias;
3. Yooj yim sib xws nrog ntau yam tshuaj lom neeg;
4.Economical thiab siv mus sij hawm ntev.
Daim ntawv thov
Nws yog siv rau cov tshuaj tua kab mob ntawm cov tshuaj ntxuav txhua hnub (cov kua ntxhua khaub ncaws, da dej gel, tshuaj zawv plaub hau, tshuaj ntxuav tes, thiab lwm yam).
Nws kuj yog siv rau tshuaj tua kab mob hauv pub, cov khoom lag luam niaj hnub, khoom siv tshuaj tua kab mob, kev lag luam textile (textile, paj rwb xov paj, tshuaj fiber ntau), thiab lwm yam.
