(Scope ntawm daim ntawv thov siv 'cov khoom siv')

① Cov muaj pes tsawg leeg, tus cwj pwm thiab cov ntsiab lus ntawm cov khoom noj yog tib yam, cov zaub mov tso tawm thiab kev nqus tau zoo ib yam, thiab cov ntsiab lus dej, hardness, plua plav cov ntsiab lus thiab thauj thiab khaws cia ntawm cov khoom sib txawv.

② Tus nqi tawg, cov zaub mov tso tawm thiab cov chiv tus nqi ntawm cov khoom sib txawv, thiab qhov sib cais ntawm cov khoom me me yog ceev thiab cov nyhuv yog ceev;Lub dissolution ntawm loj hais yog qeeb thiab lub sij hawm fertilization yog ntev.

③ Cov ntsiab lus ntawm cov urea biuret loj yog qis dua li cov khoom me me, uas yog siv los ua cov chiv chiv, lossis cov khoom loj yog siv rau kev tsim cov chiv sib xyaw.Rau topdressing, me me granular urea yog siv rau foliar txau, daim ntawv thov qhov, daim ntawv thov trench thiab sawb fertilization, thiab yaug daim ntawv thov nrog dej.

④ Loj-particle urea muaj plua plav cov ntsiab lus piv nrog me me-particle urea, siab compressive zog, zoo fluidity, muaj peev xwm thauj tau nyob rau hauv tej, tsis yooj yim rau tawg thiab caking, thiab yog haum rau mechanized fertilization.

EVERBRIGHT® ' kuj tseem yuav muab customized ： cov ntsiab lus / whiteness / particlesize / PHvalue / xim / ntim style / ntim specifications thiab lwm yam khoom tshwj xeeb uas tsim nyog rau koj cov kev siv, thiab muab cov qauv dawb.

Khoom siv

Fertilization tswj

[Hloov ntawm paj npaum li cas]Yuav kom kov yeej lub xyoo loj thiab me ntawm cov txiv apples, tshuaj tsuag 0.5% urea aqueous daws ntawm nplooj nplooj ntawm 5-6 lub lis piam tom qab paj (lub sijhawm tseem ceeb ntawm kev sib txawv ntawm cov txiv apple paj sib txawv, kev loj hlob ntawm cov tua tshiab qeeb lossis nres. , thiab cov ntsiab lus nitrogen ntawm nplooj qhia tau hais tias ib qho kev poob qis), txau ob zaug ua ntu zus, tuaj yeem ua kom cov nitrogen cov ntsiab lus ntawm nplooj, ua kom txoj kev loj hlob ntawm cov nroj tsuag tshiab, inhibit paj bud sib txawv, thiab ua kom lub paj ntawm lub xyoo loj tsim nyog.

[Paj thiab txiv hmab txiv ntoo thinning]Txiv duaj paj hauv nruab nrog cev yog rhiab heev rau urea, tab sis cov tshuaj tiv thaiv yog qeeb, yog li txawv teb chaws txiv duaj nrog urea xeem, cov txiaj ntsig tau pom tias txiv duaj thiab nectarine paj thiab txiv hmab txiv ntoo thinning, xav tau ib qho loj concentration (7.4%) los qhia cov txiaj ntsig zoo, qhov tsim nyog tshaj plaws. concentration yog 8% -12%, 1-2 lub lis piam tom qab txau, kom ua tiav lub hom phiaj ntawm paj thiab txiv hmab txiv ntoo thinning.

[Kev tsim cov noob nplej]Nyob rau hauv hybrid nplej ntau lawm technology, txhawm rau txhim kho tus nqi ntawm cov niam txiv, txhawm rau ua kom cov noob qoob loo ntau ntxiv ntawm cov nplej hybrid lossis cov qoob loo ntawm cov kab tsis muaj menyuam, qhov kev sim tau ua nrog urea es tsis txhob siv gibberellin, thiab siv. ntawm 1.5% mus rau 2% urea nyob rau hauv lub cev xeeb tub theem siab tshaj plaws thiab thawj theem pob ntseg (20% pob ntseg xaiv), cov nyhuv fertility zoo ib yam li gibberellin, thiab nws tsis ua kom cov nroj tsuag qhov siab.

[Pest Control]Nrog urea, ntxuav hmoov, dej 4: 1: 400, tom qab sib tov, tuaj yeem tiv thaiv cov txiv hmab txiv ntoo, zaub, paj rwb aphids, kab laug sab liab, kab laug sab thiab lwm yam kab tsuag, cov tshuaj tua kab ntau dua 90%.[Urea hlau chiv] Urea cov ntaub ntawv chelated hlau nrog Fe2 + nyob rau hauv daim ntawv ntawm complex.Hom organic hlau chiv no muaj tus nqi qis thiab muaj txiaj ntsig zoo ntawm kev tiv thaiv cov hlau tsis muaj zog thiab ntsuab poob.Kev tswj cov nyhuv ntawm chlorosis zoo dua li ntawm 0.3% ferrous sulfate.

Textile printing thiab dyeing

① tuaj yeem siv los ua ntau cov melamine, urea-formaldehyde resin, hydrazine hydrate, tetracycline, phenobarbital, caffeine, VAT xim av BR, phthalocyanine B, phthalocyanine Bx, monosodium glutamate thiab lwm yam khoom siv raw khoom.

② Nws muaj cov nyhuv ci ntsa iab ntawm cov tshuaj polishing ntawm cov hlau thiab stainless hlau, thiab yog siv los ua cov tshuaj tiv thaiv corrosion hauv cov hlau pickling, thiab kuj tseem siv rau hauv kev npaj cov kua palladium activation.

③ Hauv kev lag luam, nws kuj tseem siv los ua cov khoom siv raw rau kev tsim cov urea-formaldehyde resins, polyurethanes thiab melamine-formaldehyde resins.

④ Cov kev xaiv txo tus neeg sawv cev rau denitrification ntawm combustion tso pa roj, nrog rau lub tsheb urea, uas yog tsim los ntawm 32.5% high-purity urea thiab 67.5% deionized dej.

⑤ Txhawm rau cais cov kab mob paraffin (vim tias urea tuaj yeem tsim cov clathrates), cov ntaub ntawv refractory, cov khoom ntawm ib puag ncig tiv thaiv cav roj, cov khoom siv tshuaj ntxuav hniav dawb, tshuaj chiv, cov khoom siv tseem ceeb rau dyeing thiab luam ntawv.

⑥ textile kev lag luam yog ib qho zoo heev dye hnyav / hygroscopic tus neeg saib xyuas / viscose fiber expanding tus neeg saib xyuas, resin finishing agent, muaj ntau yam kev siv.Kev sib piv ntawm cov khoom hygroscopic ntawm urea nrog rau lwm cov hygroscopic agents hauv kev lag luam textile: piv rau nws qhov hnyav.

Cosmetic qib (moisturizing ingredient)

Dermatology siv qee cov tshuaj uas muaj urea los ua kom cov dej noo ntawm daim tawv nqaij.Cov hnav khaub ncaws kaw siv rau cov ntsia hlau tsis raug phais muaj 40% urea.Urea yog ib qho zoo moisturizing muaj, nws muaj nyob rau hauv daim tawv nqaij cuticle, yog daim tawv nqaij lub ntuj moisturizing yam NMF lub ntsiab tivthaiv.
