Hauv nws qhov tseem ceeb, cov xuab zeb hauv hiav txwv yog cov dej tso dej. Cov ntaub ntawv no yog qhov xav tau zoo ntawm cov kws kho mob, tus tsim khoom, tus tsim toj roob hauv pes thiab ntau lwm tus kws tshaj lij. Niaj hnub no hauv peb tsab xov xwm peb yuav tham hauv ntau yam ntxiv txog cov yam ntxwv thiab cov yam ntxwv tshwj xeeb ntawm cov khoom siv.

Muaj pes tsawg leeg thiab cov khoom

Hiav txwv xuab zeb yog homogeneous thiab muaj qib siab ntawm kev ntshiab - tsis muaj qhov tsis xav tau impurities thiab av nplaum hauv nws. Kev sib xyaw ntawm cov ntxhia ib txwm suav nrog cov tshuaj xws li quartz (rau feem ntau) thiab spar.

Quartz muaj cov txiaj ntsig tseem ceeb ntawm cov khoom siv tshuaj lom neeg ntawm cov xuab zeb hiav txwv, raws li nws tau pom los ntawm kev ntxiv dag zog thiab tiv thaiv.

Cov xim ib txwm ntawm cov ntxhia hauv hiav txwv yog beige . Txawm li cas los xij, koj tseem tuaj yeem pom lub teeb (dawb) ntau yam - feem ntau xws li cov ntxhia tuaj yeem pom hauv huab cua sov. Hiav txwv xuab zeb yog tsim los ntawm cov txheej txheem yaig hauv limestone.

Qhov loj ntawm cov khoom siv feem yog li 0.3 cm . Ntxiv rau qhov ntsuas no, cov khoom zoo li cov ntxhia thiab qhov hnyav (feem ntau ntsuas hauv kg) ua lub luag haujlwm tseem ceeb. Cov txiaj ntsig zoo ntawm cov xuab zeb tau tswj hwm los ntawm GOST.

Ib qho ntxiv, txhawm rau kom ntseeg tau tias koj tab tom yuav cov khoom lag luam zoo uas yuav ua tiav nws lub hom phiaj kev ua haujlwm, nws yog qhov tseem ceeb los tshuaj xyuas hom ntxhia hauv lub tshuab tsom iav.

Ntau yam

Cov khoom tseem ceeb ntawm cov xuab zeb hauv hiav txwv, ntawm qhov uas nws qhov kev faib tawm yog nqa tawm, yog qhov loj me, muaj pes tsawg leeg thiab cov qauv ntawm cov khoom me me uas tsim cov khoom. Yog li, cov kws tshaj lij cais 3 hom tseem ceeb:

• plua plav;
• ntxhib-grained;
• clayey.

Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov qhov tseeb tias txhua qhov ntawm ntau yam no haum rau kev ua haujlwm sib txawv. Raws li, thaum xaiv thiab yuav khoom, qhov tseeb no yuav tsum raug coj mus rau hauv tus account kom cov khoom ua tau raws li qhov koj xav tau.

Cov yam ntxwv rho tawm

Cov khoom siv ntuj tsim tau muab rho tawm thaum lub sijhawm ua haujlwm dredging (feem ntau hauv Gulf of Finland). Hauv qhov no, nws yog qhov tsim nyog siv ntau yam khoom siv tshwj xeeb, tshwj xeeb - cov plhaub hydraulic.

Tom qab ntawd, yam tsis tau ua tiav, cov xuab zeb hauv hiav txwv tau ua kom huv thiab muaj ntau theem tu . Thaum lub sijhawm txheej txheem no, ntau qhov loj me me, ntxiv rau cov khoom tsis tseem ceeb ntawm cov organic, raug tshem tawm. Ib qho ntxiv, cov ntxhia yuav tsum tau ntxuav nrog dej tshiab.

Nws yuav tsum nco ntsoov tias txhua cov txheej txheem rau kev rho tawm thiab ua kom huv ntawm cov khoom yuav tsum ua raws li cov txheej txheem lees paub thiab cov cai.

Cov ntawv thov

Cov xuab zeb hiav txwv yog cov khoom siv ntuj tsim uas tau siv dav hauv ntau thaj chaw ntawm tib neeg lub neej. Cia peb xav txog qhov nrov tshaj plaws.

Tsev . Kev tsim kho kev lag luam feem ntau xav tau cov av xuab zeb zoo. Cov khoom siv ntuj tsim tau siv hauv cov txheej txheem ntawm kev ua vaj tse, rau kev tsim ntau yam sib xyaw ua tiav, rau cov kua dej, ua lim dej, thiab lwm yam.

Kev tsim kho av . Ntawm txhua yam ntawm cov xuab zeb uas twb muaj lawm rau kev tsim kho av, nws yog cov xuab zeb hiav txwv uas zoo tshaj plaws. Nws yog siv los kho thiab kho thaj chaw ib puag ncig ntau lub tsev thiab cov qauv, nrog rau tsim rau thaj chaw pej xeem. Qhov no yog vim lub hiav txwv xuab zeb zoo thiab ci hauv lub hnub.

Cov tshuaj . Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm cov xuab zeb hiav txwv yog nws qhov huv; raws li, cov khoom siv tau nquag siv hauv tshuaj. Yog li, nws tuaj yeem siv los kho cov leeg nqaij thiab lub paj hlwb. Ib qho ntxiv, cov ntxhia hauv ntuj tau siv hauv kev tawm tsam rheumatism.

Aquarium lag luam . Feem ntau, cov xuab zeb hiav txwv ua cov txheej hauv qab hauv cov thoob dej yug ntses hauv tsev. Qhov no yog vim qhov tseeb tias cov khoom muaj ntom txaus kom cov qe tuaj yeem tso rau hauv.

Vaj . Heev feem ntau, cov xuab zeb hiav txwv tau siv los ua chiv rau lub vaj thiab zaub zaub.

Yog li, peb tuaj yeem txiav txim siab tias qhov kev thov ntawm cov khoom siv ntuj tso dej ntws dawb yog dav heev.

Cov kws tshaj lij ntawm cov ncauj lus dav yuav tsis ua yam tsis muaj xuab zeb hauv hiav txwv thaum ua tiav lawv cov haujlwm ua haujlwm.
