Iyini ukusetshenziswa okuyinhloko kwe-benzoic acid?
Ukusetshenziswa okuyinhloko:I-Benzoic acidisetshenziswa njenge-ejenti ye-bacteriostatic ye-emulsion, umuthi wamazinyo, ujamu nokunye ukudla; i-mordant yokudaya nokuphrinta; okuphakathi kwemithi kanye nodayi; ukulungiselela i-plasticizer kanye namakha; i-ejenti yensimbi yokulwa nokuvuvukala.

Kungani usebenzise i-i-benzoic acid? Umsebenzi we-benzoic acid:
(1) Ukuthuthukisa ukusebenza kwezingulube, ikakhulukazi ukusebenza kahle kokuguqulwa kokuphakelayo
(2) Isilondolozi; I-ejenti ye-antimicrobial
(3) Isetshenziselwa ikakhulukazi i-antifungal ne-antiseptic
(4) I-Benzoic acid iyisilondolozi esibalulekile sohlobo lwe-asidi
I-Benzoic acid kanye nosawoti wayo sekusetshenziswe iminyaka eminingi njengendlela yokulondoloza
ama-ejenti embonini yokudla, kodwa kwamanye amazwe futhi njengezithasiselo ze-silage, ikakhulukazi ngenxa yokusebenza kahle kwazo ngokumelene nesikhunta nemvubelo ehlukahlukene.
