| Chizindikiro chaukadaulo |
Chogulitsachi ndi 55% DMDMH madzi, pogwiritsa ntchito njira zamakono zopangira ndi ukadaulo wapadziko lonse lapansi. Cholamulidwa mwamphamvu ndi ogwira ntchito zapamwamba za R&D center, mtundu wake ndi wodalirika, chikugwirizana bwino, ndipo zotsatira zake zimakhala nthawi yayitali popanda kukhudza mawonekedwe, fungo ndi magwiridwe antchito a chinthucho. Ndi chotetezeka komanso chopanda poizoni. Chingagwiritsidwe ntchito m'mitundu yosiyanasiyana ya PH = 5-12. Ndi kutsuka, emulsion Ndi mankhwala abwino kwambiri opha tizilombo komanso opha tizilombo toyambitsa matenda pa zodzoladzola monga, kirimu, ndi zina zotero. | ||||||||||||||||||||||
| Khalidwe | Fungicide ndi yothandiza kwambiri, yotsika mtengo, yosavuta kugwiritsa ntchito, imasungunuka mosavuta m'madzi ndi mowa wochepa, komanso imakhazikika mu emulsions yamadzi ndi mafuta. Imagwirizana ndi ma surfactants a cationic, anionic ndi nonionic, ma emulsifiers ndi mapuloteni. Ndi yokhazikika pakapita nthawi, pH yochuluka komanso kutentha kwakukulu. | ||||||||||||||||||||||
| Kugwiritsa ntchito komwe kukulimbikitsidwa | Chifukwa cha kusungunuka kwake kwapadera kwa madzi, DMDMH ikhoza kuwonjezeredwa ku mafuta odzola ndi mankhwala osamalira thupi omwe ali ndi kuchuluka kwa 0.2 ~ 0.6%. Ngati DMDMH yonjezedwa ku surfactant, kutentha kwake nthawi zambiri kumakhala 50℃ ~ 60℃, ndipo pH imakhala pakati pa 7.5 ~ 8.5. Popeza zosakaniza ndi mankhwala osamalira thupi zimasiyana kwambiri, zomwe zingakhudze mphamvu ya zosungira, tikukulimbikitsani kuti mutsimikizire kuti DMDMH imagwira ntchito bwino komanso kuti zinthu zosungira thupi sizikukhazikika. |
Lembani uthenga wanu apa ndipo mutitumizireni
