Urea

Incazelo emfushane:

Kuyindlela ehlanganisiwe ehlanganiswa ikhabhoni, i-nitrogen, i-oksijini ne-hydrogen, futhi ingumkhiqizo oyisipele we-organic oqukethe ama-protein metabolism kanye nokubola kwezilwane ezincelisayo kanye ne-carbon dioxide embonini ngaphansi kwezimo ezithile.

① Ukwakheka, umlingiswa kanye nokuqukethwe kwezakhi zomsoco kuyafana, ukukhululwa kwezakhi kanye nemodi yokumunca kuyafana, futhi okuqukethwe kwamanzi, ubulukhuni, ukumelana nothuli nezinhlayiya zokuhambisa kanye nokugcina izinhlayiya zehlukile.

Izinga lokuchithwa, isilinganiso sokukhishwa kwezakhi zomzimba kanye namanje kumanyolo wezinhlayiya ahlukile, futhi izinga lokuchithwa kwezinhlayiya ezincane ngokushesha futhi umphumela uyashesha; Ukuchithwa kwezinhlayiya ezinkulu kuhamba kancane futhi isikhathi sokuvundiswa side.

Okuqukethwe i-biuret enkulu ye-urea iphansi kunaleyo yezinhlayiya ezincane, ezisetshenziswa njengomanyolo wesisekelo, noma izinhlayiya ezinkulu zisetshenziselwa ukukhiqizwa komanyolo ohlanganisiwe. Ngokufaka i-toplerring, i-urea encane ye-granular isetshenziselwa ukufafaza i-foliar, uhlelo lokusebenza lwe-hole, uhlelo lokusebenza lomsele kanye nokuvundiswa kwe-strip, kanye nesicelo se-flush ngamanzi.

I-Urea eningi-eziyizinhlayiyana inokuqukethwe okuphansi kothuli uma kuqhathaniswa ne-urea encane-eyizinhlayiya, amandla aphezulu acindezela, uketshezi oluhle, kungahanjiswa ngobuningi, akulula ukuphula nokuvuka, futhi kufanelekile umanyolo.

I-EverBright® 'LL futhi ihlinzeka ngezifiso: okuqukethwe / okumhlophe / izinhlayiya / phvalue / ukufakwa kombala / ukufakwa kwemininingwane / ukufakwa kwemikhiqizo ethile efanelekile ngezimo zakho zokusebenzisa, futhi zinikeze amasampula wamahhala.

Ukusetshenziswa Komkhiqizo

Ukulawula Ukuvundiswa

[Ukulungiswa kwenani lembali]Ukuze unqobe unyaka omkhulu nomuncane wenkambu ye-Apple, ufafaza isisombululo esingamakhemikhali esingu-0,5% esiseleni esingu-5-6 ngemuva kokuqhakaza amaqabunga, ukusheshisa ukukhula kwamaqabunga amasha, uvimbela ukwahluka kwezimbali okusha, futhi wenze Inani lezimbali lonyaka omkhulu lifanele.

[Izimbali nokuthelwa kwezithelo]Izitho zezimbali ze-Peach zizwela kakhulu e-Urea, kepha ukusabela kuhamba kancane, ngakho-ke i-peach yakwamanye amazwe ngokuhlolwa kwe-urea, imiphumela ekhombisa ukubonwa okungu-8% - idinga ukugcwala kwezimbali, ukufeza inhloso yokufafaza izimbali nokuthengwa kwezithelo.

[Ukukhiqizwa Kwembewu yeRice Rice]Ebuchwepheshe bokukhiqizwa kwembewu ye-hybrid, ukuze bathuthukise inani labazali abangaphandle, ukuze bandise inani lokukhiqizwa kwembewu ye-hybrellin, kanye nokukhethwa kwendlebe okungu-1% (Ukusetshenziswa kwendlebe okungu-20%), umphumela wokuqina wendlebe), futhi akuzange kukhuphule ukuphakama kwezitshalo.

[Ukulawulwa Kwezinambuzane]Nge-Urea, i-Wider yokuwasha, amanzi 4: 1: 400, ngemuva kokuxubana, imifino, ama-aphid kakotini, izinambuzane ezibomvu nezinye izinambuzane, izinambuzane ezingaphezu kwama-90%. [U-Urea Iron Umanyolo] Urea Amafomu ahlenge i-iron nge-FE2 + ngesimo esiyinkimbinkimbi. Lolu hlobo lomanyolo wensimbi organic lunezindleko eziphansi nomphumela omuhle ekuvikeleni ukuntuleka kwensimbi nokulahlekelwa okuluhlaza. Umphumela wokulawula we-chlorosis ungcono kunaleso-0.3% Ferrous Sulfate.

Ukuphrinta Kwendwangu nokudaya

Ingasetshenziswa njengenombolo enkulu ye-melamine, i-urea-formaldehyde resin, i-hydrazine hydrate, i-veTracycline, i-phefeine, i-vat brown br, i-phthalocyanine b, i-phthalocyanine BX, i-monosodium gluamate field.

② Inomphumela wokuqhakambisa kokupholizwa kwamakhemikhali kwensimbi nensimbi engenasici, futhi isetshenziswa njenge-inhibion ye-corrolusion ekuhambeni kwensimbi, futhi iyasetshenziswa lapho kulungiswa i-Palladium activation ketshezi.

Embonini, isetshenziswa futhi njengento eluhlaza yokwenziwa kwe-Urea-formaldehyde resins, ama-polyurethanes kanye nama-melamine-formaldemdehyde desins.

④Umenzeli okhethiwe wokunciphisa ukudicilelwa kwegesi yokuvula amandla, kanye ne-urea yezimoto, ehlanganiswa ngo-32,5% wokuhlanza ubuhlanya obukhulu kanye namanzi angama-67,5%.

⑤ Ukuhlukanisa i-paraffin wax (ngoba u-Urea ungakha ama-Clathrates), izinto zokuzenzakalelayo, izingxenye zamafutha enjini yokuvikela imvelo, izingxenye zemikhiqizo yamazinyo amhlophe, umanyolo wamakhemikhali, ama-ejenti abalulekile wokudaya nokuphrinta.

Imboni ye-Textile Industry udayi omuhle kakhulu wedayi / i-hygroscopic ejenti / i-viscose fiber alent ekhula ejenti, i-resin yokuqeda i-ejenti, inezinhlobonhlobo zokusetshenziswa. Ukuqhathanisa izakhiwo ze-hygroscopic ze-urea nezinye ama-hygroscopic agents embonini yezindwangu: isilinganiso sibe sesisindo saso.

Ibanga lokugcotshwa (umswakama izithako)

I-Dermatology isebenzisa ama-ejenti athile aqukethe u-Urea ukukhulisa umswakama wesikhumba. Ukugqoka okuvaliwe okusetshenziselwa izipikili ezisuswe ngokungafanele kuqukethe u-40% urea. U-Urea uyisithako esihle sokuthambisa, ukhona ku-cuticle yesikhumba, yisikhumba semvelo semvelo ye-NMF.
