Kagwiritsidwe Ntchito
Gallic acid (GA), yomwe imadziwikanso kuti gallnut acid, ndi gawo la ma tannins omwe amatha kusungunuka ndipo dzina lake ndi 3,4, 5-trihydroxybenzoic acid. Gallic acid ili ndi kuchuluka kwakukulu mu tiyi ya Yunnan Pu 'er ndipo ili ndi zotsatira zambiri zamoyo monga mabakiteriya, kutupa, chotupa komanso kuphwanya kusintha kwa maselo.
Gallic acid imagwiritsidwa ntchito kwambiri mu mankhwala, inki, utoto, chakudya, makampani opanga kuwala ndi kupanga zinthu zachilengedwe, ndi zina zotero. Gallic acid imagwira ntchito ndi ma ayoni achitsulo atatu kuti ipange mtundu wa buluu wakuda, womwe ndi chinthu chopangira inki yabuluu wakuda. Imagwiritsidwanso ntchito m'makampani popanga zikopa. Ingagwiritsidwenso ntchito ngati wopanga zithunzi. Propyl gallate ndi antioxidant ndipo ingagwiritsidwe ntchito mu mafuta odyedwa ndi mafuta kuti ipewe kuwonongeka ndi kuwonongeka. Mu mankhwala, gallic acid ndi mankhwala oletsa magazi komanso oletsa kutsekeka kwa magazi, komanso imachepetsa mkwiyo wa m'deralo.
Ili ndi mphamvu yoletsa mabakiteriya ndipo ingagwiritsidwe ntchito pochiza matenda a m'mimba otchedwa bacillary. Ili ndi mphamvu yoletsa kutsekeka kwa magazi, magazi otuluka m'thupi komanso yoletsa kutsegula m'mimba. Ingagwiritsidwe ntchito ngati chosungira. Ingagwiritsidwe ntchito pokonzekera pyrogallic acid, mankhwala, inki, utoto wapakati komanso mankhwala oletsa kuphulika, ndi zina zotero. Imagwiritsidwanso ntchito ngati wopanga komanso wowunikira kuti azindikire ma inorganic acids aulere, dihydroxyacetone, alkaloids ndi zitsulo, ndi zina zotero.
Itha kugwiritsidwa ntchito ngati chosungira, ndipo ingagwiritsidwe ntchito pokonzekera utoto wapakatikati ndi zinthu zotsutsana ndi kuphulika, ndi zina zotero.
Amagwiritsidwa ntchito ngati chothandizira cha mankhwala
Amagwiritsidwa ntchito makamaka ngati chopaka utoto cha inki yabuluu-yakuda. Amagwiritsidwa ntchito mumakampani opanga mankhwala kukonzekera sulfonamide potentiator TMP komanso ngati chophatikiza cha sulfonamides monga SMZ ndi SD-ethyl. Makampani opanga chakudya amagwiritsa ntchito izi kukonzekera gallic acid yosungira. Amagwiritsidwa ntchito mumakampani opanga chitetezo kukonzekera zinthu zoteteza kuphulika. Kuphatikiza apo, ingagwiritsidwenso ntchito popanga utoto wa mordant komanso ngati wopanga, ndi zina zotero.
Amagwiritsidwa ntchito ngati depolarizer mu kusanthula kwa electrochemical; amagwiritsidwa ntchito pochepetsa phosphomolybdic acid; amagwiritsidwa ntchito pozindikira antimony, barium, bismuth, calcium, cerium, copper, etc.; amagwiritsidwa ntchito pozindikira phosphorous, nitrite, siliva, thorium, titanium, ndi zina zotero.
Phenolic acid yomwe imasungunuka m'madzi, yomwe imapezeka m'masamba a mphesa ndi zomera zambiri, ndi antioxidant yothandiza kwambiri.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
