Potassium nitrate (los yog potassium nitrate) yog nitrogen-potassium complex fertilizer siv los pub ntau yam nroj tsuag. Nws yog qhov tseem ceeb tshaj plaws ntawm cov poov tshuaj rau txhua cov qoob loo, thiab nws tuaj yeem siv rau txhua theem ntawm lawv txoj kev loj hlob. Cov chiv no tau nthuav tawm hauv daim ntawv ntawm cov hmoov zoo crystalline ntawm cov xim dawb-greyish. Nws yog soluble tag nrho hauv dej, nws tsis muaj Na thiab Cl ntsev, nrog rau cov hlau hnyav.

thaj chaw thov

Potassium nitrate yog cov chiv uas tshwj xeeb tshaj yog rau cov av nrog nruab nrab thiab siab phosphorus compounds. Nws yog qhov zoo dua los siv nws nyob rau lub caij nplooj ntoo hlav, vim tias yog tias qhov no ua tiav thaum lub caij nplooj zeeg, tom qab ntawd cov nitrate nitrogen muaj nyob rau hauv cov chiv no yuav raug ntxuav rau hauv cov av qis thaum lub caij nplooj zeeg thiab lub caij ntuj no, uas yuav ua rau ob lub sijhawm tsis zoo: ua ntej, av. dej,Thib ob, cov chiv yuav dhau los ua tsis tau rau cov nroj tsuag lawv tus kheej. Tsis tas li ntawd, potassium nitrate yog siv los fertilize cov qoob loo uas cuam tshuam los ntawm cov tshuaj chlorine-potassium chiv. Potassium nitrate

kuj pom zoo rau cov ntawv thov foliar thiab hauv fertigation systems. Nrog nws cov kev pab, foliar pub mis ntawm lub caij ntuj no nplej thaum lub sij hawm earing lub sij hawm kuj yog nqa tawm (3 kg ntawm chiv ib 200 liters dej yog tus qauv ib 1 hectar). Txhawm rau pub cov nroj tsuag hauv tsev cog khoom, kev daws teeb meem yog npaj hauv qhov piv ntawm 50 g / 10 liv dej.

qauv kev nyab xeeb

Properties. Potassium nitrate yog ib qho muaj zog oxidizing tus neeg sawv cev. Nws teb nrog

txo cov neeg ua haujlwm thiab cov khoom siv hluav taws xob. Nws qhov ceev yog 2.109 g / cm³, lub boiling point yog 400 ° C, thiab melting point yog 334 ° C. Cov tshuaj potassium nitrate yog cov tshuaj lom heev, yog li nws qhov siab tshaj plaws tso cai rau cov huab cua hauv thaj chaw muaj kev lag luam yuav tsum tsis pub tshaj 5 mg / m2. Thaum nqus tau cov poov tshuaj nitrate vapor, rwj thiab edema yuav tshwm sim ntawm qhov ntswg mucosa, thiab nrog kev sib cuag ntev, thickenings tshwm rau ntawm daim tawv nqaij ntawm xib teg thiab ko taw. Tsis tas li ntawd, qhov txaus ntshai ntawm cov tshuaj no yog nyob rau hauv nws lub peev xwm los provoke spontaneous combustion ntawm combustible tshuaj. Hauv qhov no, ua kom hluav taws lossis haus luam yeeb ze dua 50 meters los ntawm qhov chaw khaws cia, thauj khoom thiab tshem tawm cov poov tshuaj nitrate yog nruj me ntsis txwv. Qhov tshwj xeeb txaus ntshai yog qhov tau txais cov poov tshuaj nitrate hauv tsev. Thaum twgYog tias muaj hluav taws tshwm sim, cov hmoov qhuav los yog cov tshuaj tua hluav taws ua npuas dej, cov dej ntau, cov xuab zeb qhuav lossis cov pam asbestos siv los tua hluav taws.

Kev thauj mus los thiab khaws cia

Thaum lub sijhawm thauj khoom thiab tshem tawm cov haujlwm, kev siv tshuab thiab kev sib khi ntawm cov khoom hauv cov thawv tsim nyog yuav tsum tau muab, thiab cov chaw muaj plua plav yuav tsum tau nruab nrog lub qhov tso pa tawm. Cov neeg ua haujlwm hauv kev sib cuag nrog potassium nitrate thaum ua haujlwm yuav tsum tau hnav khaub ncaws tshwj xeeb, tseem yuav tsum muaj cov khoom siv tiv thaiv tus kheej uas ua tau raws li cov qauv kev lag luam. Potassium nitrate yog khaws cia rau hauv cov pob tshwj xeeb hauv cov tsev khaws khoom kaw. Tsis txhob thauj thiab khaws cov khoom ua ke nrog cov ntxhia acids thiab cov khoom siv hluav taws xob, nrog rau kev sib xyaw nrog straw, sawdust, peat, thee thiab lwm yam khoom siv organic, vim qhov no yuav ua rau hluav taws kub lossis tawg.
