① Qhov muaj pes tsawg leeg, tus cwj pwm thiab cov ntsiab lus ntawm cov zaub mov zoo ib yam, cov ntsiab lus dej, thiab cov ntsiab lus plua plav thiab cov plua plav tsis kam ntawm cov khoom sib txawv.
Dission Txoj Kev Noj Qab Haus, Cov Khoom Siv Hluav Taws Xob ntawm cov khoom sib txawv, thiab cov kev sib txawv ntawm cov khoom me me yog nrawm thiab cov nyhuv ceev; Kev sib cais ntawm cov ceg loj yog qeeb thiab lub sijhawm muaj kev sib tw ntev.
Cov ntsiab lus ntawm urea loj loj tshaj qhov tsawg dua li ntawm cov lus me me, uas yog siv los ua cov khoom siv hauv paus, lossis cov khoom loj yog siv rau kev sib xyaw ua ke chiv. Rau saum eprressing, me me granular urea yog siv rau foliar txau, lub qhov ntawv thov, trenip daim ntawv thov, thiab yaug fertilization, thiab yaug tso dej.
④ Cov plua av loj loj muaj cov plua plav tsis tshua muaj zog piv nrog kev ua kom muaj zog me me, tuaj yeem thauj tau yooj yim thiab ua kom haum rau kev siv tshuab fertilization.
Evenbright® 'LL tseem muab cov ntsiab lus customized: Cov ntsiab lus / Partenize / Phaj Cov Khoom Siv thiab cov khoom tshwj xeeb uas haum rau koj siv cov xwm txheej, thiab muab cov qauv dawb.

Kev tswj kev tswj hwm
[Kho kom haum ntawm cov paj paj]Nyob rau hauv thiaj li yuav kov yeej ntau loj thiab xyoo hauv lub txiv apple, txau ob peb zaug ntawm cov nplooj ntoo tshiab, insibit paj tawg, insibit paj bud sib txawv, thiab ua kom cov paj ntau lub xyoo tsim nyog.
[Paj thiab txiv hmab txiv ntoo thinning]Cov paj yeeb dawb yog qhov xav tau ntau dua, tab sis cov tshuaj tsw qab yog 8%, yog li cov txiv hmab txiv ntoo ua yeeb yam, yog li cov txiv hmab txiv ntoo ua yeeb yam, yog 1-2 lub vas sab tom qab tshuaj ntxuav, kom ua tiav lub hom phiaj paj thiab txiv hmab txiv ntoo thinning.
[Cov Noob Txiv Ntoo Ntau Lawm]Nyob rau hauv hybrid nplej muag cov noob ntau lawm tshuab, nyob rau hauv kev xaiv ntau dua ntawm cov noob ua si, thiab kev sim ua pob ntseg (20% pob ntseg sib tw
[Kab Tsuag Tswj]Nrog urea, ntxhua hmoov, dej 4: 1: 400, tuaj yeem tiv thaiv cov txiv hmab txiv ntoo, cov kab tsuag liab, cov kab xev, tshuaj ntsuab kab mob ntau dua 90%. [Urea hlau chiv] urea hom chelated hlau nrog FE2 + nyob rau hauv daim ntawv ntawm cov nyom. Cov organic hlau chiv muaj tus nqi tsawg thiab muaj txiaj ntsig zoo rau kev tiv thaiv cov khoom lag luam hlau tsis txaus thiab ntsuab poob. Kev tswj hwm kev ua haujlwm ntawm cov tshuaj chlorosis zoo dua li ntawm 0.3% ferrous sulfate.
Textile Printing thiab Dyeing
Siv tau ntau npaum li cas los ua melamine ntau, hydrate hydrate, pthalorocyanine B, Phatesocyanine B, Phatorocyanine B, Phathodium Glutamate thiab lwm yam khoom lag luam ntau lawm cov khoom siv
Nws muaj cov txiaj ntsig zoo ntawm cov tshuaj polishing ntawm cov hlau thiab siv ua cov hlau corrosion, thiab tseem siv nyob rau hauv kev npaj ntawm palladium activation kua.
③ Hauv kev lag luam, nws tseem siv los ua cov khoom siv ua haujlwm rau kev tsim khoom ntawm urea-formaldehyde resins, polyurethanes thiab melamine-formaldehyde resins.
④Tus xaiv tus neeg sawv cev rau kev txwv rau kev sib txuas ntawm cov roj sib zog, nrog rau 32.5% high-purity urea thiab 67.5% dej deionized.
⑤ cais tawm cov quav paraffin (vim tias urea tuaj yeem tsim cov roj av), cov tshuaj txhuam hniav, tseem ceeb ib tug sawv cev rau zas thiab luam ntawv.
⑥ Kev lag luam textile yog ib qho zoo tshaj plaws pleev xim / Hygroscopic tus neeg sawv cev / Viscose fiber ntau cov neeg sawv cev, tus sawv cev ua tiav, muaj ntau yam ntawm kev siv. Kev sib piv ntawm cov khoom siv hygroscopic ntawm urea nrog lwm hygroscopic cov neeg sawv cev hauv kev lag luam textile: piv rau nws tus kheej qhov hnyav.
Cov qib ua kom zoo nkauj (moisturizing muaj)
Dermatology siv qee cov neeg ua haujlwm muaj urea kom nce cov dej noo ntawm daim tawv nqaij. Qhov kev hnav khaub ncaws kaw tau siv rau qhov tsis raug phais tshem tawm ntawm cov ntsia hlau muaj 40% urea. Urea yog qhov ua tau zoo moisturizing muaj, nws muaj nyob rau hauv daim tawv nqaij cuticle, yog daim tawv nqaij lub ntuj yahuab ua ke.
