He pyrone derivative ka waikawa Dehydroacetic, i hana pinepine ʻia e ka dimerization base-catalyzed o diketene. Hoʻohana ʻia ia ma ke ʻano he mea mālama i nā huahana lāʻau lapaʻau, meaʻai a me nā mea hoʻonaninani.
ʻO nā kūlana lāʻau lapaʻau lua no ka hoʻopili ʻana i ka kaohi maikaʻi, hāʻawi i nā keʻena hoʻokolohua pharma a me nā mea hana me kahi koho kūpono a kūpono hoʻi i ke kumukūʻai no ka hoʻomākaukau ʻana i nā kūlana hana kūloko.

Hoʻohana
Hoʻohana ʻia ka waikawa Dehydroacetic (DHS) ma ke ʻano he mea hoʻopaʻa no nā huahana hoʻonani a me nā huahana lāʻau lapaʻau ma muli o kāna hana fungicide a me bactericide, ma ke ʻano he mea hoʻohui no nā PVC-stabilizers a no ka syntheses o nā lāʻau lapaʻau holoholona. Pepa ʻIkepili Huahana
Hoʻokumu ʻia ka mea mālama ʻo Geogard(R) 111a ma ka waikawa dehydroacetic (DHA) a no laila ua ʻike ʻia e nā luna hoʻoponopono hoʻonaninani, nā mea hoʻomaʻemaʻe a me nā mea ʻala ma ka honua holoʻokoʻa no ka hoʻohana ʻana i nā huahana hoʻonaninani a me nā huahana mālama pilikino.
Hoʻokumu ʻia ka mea mālama ʻo Geogard(R) 221 ma ka waikawa dehydroacetic (DHA) a me ka waiʻona benzyl, a no laila ua ʻike ʻia e nā luna hoʻoponopono hoʻonaninani, nā mea hoʻomaʻemaʻe a me nā mea ʻala ma ka honua holoʻokoʻa no ka hoʻohana ʻana i nā huahana hoʻonaninani a me nā huahana mālama pilikino.
Hoʻokumu ʻia ka mea mālama ʻo Geogard(R) 361 ma luna o ʻeono mau ʻāpana synergistic, a pau me ka ʻae ʻia ʻana o nā lula honua ākea: dehydroacetic acid (DHA); salicylic acid; benzoic acid; phenoxyethanol; benzyl alcohol; a me benzethonium chloride.
antifungal, antibacterial
He mea mālama ka waikawa dehydroacetic me ka hiki ke hoʻonāukiuki haʻahaʻa. He waikawa nāwaliwali kēia i hoʻohana ʻia ma ke ʻano he mea luku fungi a me bacteria i nā mea hoʻonani. ʻO ke alo o nā mea olaola e hoʻemi ana i kona pono. ʻAʻole ia he mea hoʻonāukiuki a i ʻole he mea hoʻoulu i ka maʻi allergy ke kau ʻia ma ka ʻili.
ʻO ka Dehydroacetic Acid (DHA) kahi mea mālama i hana ʻia me ka pauka crystalline me ka solubility ma lalo o 0.1 g i loko o 100 g o ka wai ma 25°C. Hiki iā ia ke hana i nā ʻano hopena kemika like ʻole e hāʻawi iā ia i ka pono ma nā noi he nui. Hoʻohana ʻia ia ma 0.01–0.5% no ka pale ʻana i ka ulu ʻana o ka microbiological i nā meaʻai like ʻole. Hoʻohana ʻia ia no ka squash i ʻoki ʻia a i ʻili ʻia paha, me ka ʻole o 65 ppm i koe i loko a i ʻole ma luna o ka squash i hoʻomākaukau ʻia.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
