| Indekisi yehunyanzvi |
Ichi chigadzirwa 55% DMDMH aqueous solution, uchishandisa ichangoburwa yepasirese yekugadzira fomula uye tekinoroji. Kunyatsodzorwa nepamusoro-tech vashandi veR & D centre, hutano hwakavimbika, kuwirirana kwakanaka, uye mhedzisiro yacho inogara kwenguva refu pasina kukanganisa chigadzirwa Kuonekwa, kunhuwa uye kushanda. Yakachengeteka uye haina chepfu. Inogona kushandiswa muhuwandu hwakawanda hwePH = 5-12. Iyo inogeza, emulsion Iyo yakanaka antiseptic uye antibacterial agent yezvizoro senge, cream, nezvimwe. | ||||||||||||||||||||||
| Hunhu | High-effective, yakaderera-mutengo fungicide, nyore kushandisa, nyore soluble mumvura uye yakaderera doro, uye kugadzikana mumvura uye mafuta chikamu emulsions. Inoenderana ne cationic, anionic uye nonionic surfactants, emulsifiers uye mapuroteni. Yakagadzikana nekufamba kwenguva, yakafara pH uye tembiricha renji. | ||||||||||||||||||||||
| Yakakurudzirwa kushandiswa | Nekuda kwekunyungudika kwayo kwemvura kwakasiyana, DMDMH inogona kuwedzerwa kune makirimu uye kugeza-kubvisa magadzirirwo ega ega ane denderedzwa re 0.2 ~ 0.6%. Kana DMDMH yawedzerwa kune surfactant, tembiricha yayo inowanzo 50 ℃ ~ 60 ℃, uye pH iri muhuwandu hwe7.5 ~ 8.5. Sezvo zvinongedzo uye magadzirirwo ezvigadzirwa zvekuchengetedza ega zvichisiyana zvakanyanya, izvo zvinogona kukanganisa kushanda kwezvidziviriro, isu tinokurudzira zvakasimba kuti usimbise kushanda uye kugadzikana kweDMDMH isati yagadzirwa. |
