Tam sim no tsis yog ib qho yooj yim pom cov hniav nyiaj hniav kub ntawm ib tug neeg. Tab sis tsis yog txhua leej txhua tus paub tias muaj ntau yam qauv ntawm cov khoom kub. Hauv kab lus no, peb yuav ua tib zoo saib ntawm 375 tus qauv, thiab nws txawv li cas ntawm 585 tus qauv.
Qhov pov thawj kub yog dab tsi?
Kev ntsuas kub yog qhov txhais ntawm cov hlau muaj txiaj ntsig ntau npaum li cas hauv cov hlau, thiab cov no kuj yog cov nyiaj tshwj xeeb uas muab tso rau hauv cov khoom kom ntseeg tau tias muaj cov hlau muaj txiaj ntsig hauv cov hniav nyiaj hniav kub. Txoj cai saib xyuas ob qho tib si cov hniav nyiaj hniav kub thiab cov chaw muag khoom. Tam sim no muaj plaub qhov kev ua piv txwv ua haujlwm. Cov ntawv pov thawj kub nrov suav nrog: 375, 585, 750, 958.
375 kub pov thawj: nws yog dab tsi?
Cov khoom ua los ntawm kub ntawm cov qauv no yog qhov zoo tshaj plaws. Tab sis hauv qee lub tebchaws hauv ntiaj teb, 375 thiab 333 cov qauv tseem raug lees paub. Hauv kev tsim cov hniav nyiaj hniav kub niaj hnub, qauv 375 yog qhov tsawg heev, txij li cov hlau no pib tsaus rau hauv huab cua tom qab lub sijhawm luv luv. Txawm li cas los xij, koj tuaj yeem nrhiav tau ntau cov hniav nyiaj hniav kubcov khoom lag luam nrog cov cim ntawm 375 cov qauv kub. Nws yog dab tsi? Qhov no yog ib qho piv txwv nrog cov ntsiab lus tsawg ntawm cov hlau muaj txiaj ntsig hauv nws daim ntawv purest. Nws cov ntsiab lus tsuas yog 37.5%, txhua yam yog impurities. Cov qauv no muaj tsib lub cim.
Yuav ua li cas muaj impurities cuam tshuam rau cov khoom thiab xim?
- Yog tias feem pua ntawm tooj liab siab, ces cov hniav nyiaj hniav kub yuav muaj xim liab lossis daj. Tsis tas li, tooj liab tuaj yeem txo cov khoom tiv thaiv corrosion, uas muaj kev cuam tshuam tsis zoo rau cov khoom tiav.
- Yog feem pua ntawm cov nyiaj siab, ces cov hniav nyiaj hniav kub yuav daj los yog dawb. Vim yog cov ntsiab lus nyiaj ntau ntxiv, cov khoom lag luam ua elastic dua thiab tso cai rau koj los tsim cov qauv zoo.
Yog tias koj tsis hnav thiab ntxuav cov hniav nyiaj hniav kub nrog cov khoom tawg zoo li lub sijhawm ntev heev, tom qab qee lub sijhawm cov khoom kub no yuav tsaus thiab ua tsis zoo rau hnav. Qhov kev ntsuam xyuas 375th muaj qhov sib txawv ntawm lwm cov qauv - lawv zoo heev, tab sis lawv tsis zoo.
Tab sis koj yuav tsum tsis txhob tsis quav ntsej cov khoom lag luam nrog cov qauv no, vim tias me me koj tuaj yeem yuav tau ib lub nplhaib zoo nkauj lossis qhwv ntsej, thiab yog tias koj muab cov khoom lag luam zoo nkauj no nrog kev saib xyuas zoo, lawv yuav muaj peev xwm txaus siab rau koj. ntau xyoo ntxiv. Cov khoom no muaj tus nqi tsim nyog piv rau 750 kub.
375 qhov tseem ceeb
Yav dhau los, 375th qauv ntawm kub tau tshuaj xyuas kom meej - nws yog dab tsi. TABSISTam sim no cia peb saib xyuas qhov txawv ntawm qhov qauv no:
- Ua ntej tshaj plaws, cov hlau no tsuas yog 37.5% cov kub ntshiab (raws li tau tham ua ntej).
- Thib ob, cov hlau nyob hauv cov kub no muaj ob yam hlau muaj txiaj ntsig - nyiaj thiab tooj liab.
- Thib peb, hauv tebchaws Russia tsuas muaj tsib alloys uas tau tso cai siv 375 tus qauv kub.
- Fourthly, cov alloys yog siv nyob rau hauv tsawg qhov ntau, raws li lawv qhov zoo yog tsawg, thiab dhau sij hawm, cov khoom tsim los ntawm lawv tig mus rau hauv tarnished pieces, uas yog heev nyuaj rau rov qab mus rau lawv cov qub tsos zoo nkauj.
- Cov khoom ua los ntawm 375 alloys tuaj yeem muaj xim los ntawm daj mus rau xim liab, txhua yam yuav nyob ntawm qhov feem ntawm cov hlau uas muaj yeej.
- Cov tawv tawv thiab zoo tshaj plaws yog xim liab.
- Ntiv nplhaib yog suav tias yog cov khoom siv nrov tshaj plaws uas siv 375 tus qauv.
375 kub alloys
Raws li twb tau hais lawm, kub ntawm cov qauv no yog sawv cev los ntawm cov hlau ntawm cov nyiaj thiab tooj liab. Los ntawm qhov no nws ua raws li cov alloys nrog ntau feem pua ntawm cov nyiaj thiab tooj liab tuaj yeem paub qhov txawv:
- Yog tias cov hlau muaj 37.5% kub yog xim liab, cov nyiaj yuav tsuas yog 2% thiab tooj liab 60.5%.
- Yog cov hlau yog xim liab, qhov sib piv ntawm kub yog 37.5%, cov nyiaj yuav tsuas yog 10%, thiab tooj liab - 52.5%.
- Yog cov hlau yog liab, qhov feem ntawm kub yog 37.5%, nyiaj yog 16%, thiab tooj liab yog 62.5%.
Txhua tuscov npe alloys tuaj yeem raug suav hais tias yog qib qis, thiab yog li ntawd lawv tsis nrov nyob txawv teb chaws. Tab sis yog tias koj mus xyuas UK lossis Tebchaws Meskas, koj paub tseeb tias yuav tuaj hla ntau yam ntawm 375 cov ntaub ntawv pov thawj. Ua ntej yuav cov hniav nyiaj hniav kub los ntawm 375, koj yuav tsum kawm paub meej txog 375 cov neeg siv khoom kub tshuaj xyuas.
Reviews
Ntau zaus, ua ntej yuav ib daim ntawm cov hniav nyiaj hniav kub, lawv thawj zaug nyeem cov kev tshuaj xyuas, saib cov duab ntawm cov khw muag khoom hniav nyiaj hniav kub, kawm cov kev xav ntawm cov neeg yuav khoom, thiab tsuas yog tom qab ntawd xaiv qhov kawg. Ntawm qhov tod tes, txoj hauv kev no tuaj yeem ua rau muaj kev nyab xeeb zoo heev, txij li hauv lub khw koj tuaj yeem raug dag thiab qhia ntau yam lus sib txawv, tsuas yog muag koj cov khoom. Ntawm qhov tod tes, koj yuav tsum tsis txhob tso siab rau txhua yam uas tau sau hauv Is Taws Nem, thiab ntau ntxiv rau cov rooj sab laj txog 375 kub. Kev tshuaj xyuas yuav txawv, vim tias koj tsis tuaj yeem txaus siab rau txhua tus, thiab txhua tus muaj qhov sib txawv.
Tab sis yog tias koj txheeb xyuas tag nrho cov lus teb, yuav muaj qhov tsis zoo ntau dua li qhov zoo, thiab qhov no yog tag nrho vim tsuas yog qhov tsis zoo ntawm qhov kev sim no - tsis zoo thiab tsis muaj zog. Txawm tias qhov no tuaj yeem sib cav, txij li txhua yam yuav nyob ntawm kev saib xyuas ntawm cov khoom, thiab yog tias nws yog, ces txawm tias cov khoom siv nyiaj tsawg tuaj yeem siv sijhawm ntev.
qhov txawv ntawm 585 kub thiab 375 kub yog dab tsi?
Cia peb saib kom ze rau qhov sib txawv ntawmCov hniav nyiaj hniav kub zoo nkauj nrog kev sim sib txawv:
1. Cov ntsiab lus kub sib txawv hauv cov khoom: hauv 375th qauv - 37.5%, thiab hauv 585th qauv - 58.5%.
2. Lub zog hauv cov khoom uas muaj cov ntsiab lus kub tsawg yog siab dua hauv cov khoom uas muaj qhov siab. Nws twb tau hais ua ntej txog qhov no - 375 tus qauv kub: nws yog dab tsi?. Cov khoom lag luam nrog cov qauv no yog qhov ruaj khov, thiab yog li feem ntau lawv yuav cov nplhaib kab tshoob nrog cov qauv no.
3. Tsis tas li ntawd, cov khoom uas muaj feem pua ntawm kub yuav kim dua li cov khoom uas muaj feem pua qis dua. Yog li ntawd, tus nqi qis ntawm cov khoom nrog 375 kub purity tuaj yeem piav qhia.
4. Cov hniav nyiaj hniav kub nrog 585 nrog rau 375 yog qhov ruaj khov thiab lub teeb, thiab cov khoom zoo no tso cai rau koj los tsim cov khoom zoo.
Yog tias koj tsis xyuam xim rau cov cai tswjfwm thiab cov stereotypes, tab sis tseem muab kev nyiam rau kev ua haujlwm ntev thiab siv tau, ces koj yuav tsum saib cov kev xaiv nyiaj txiag xws li 375 kub.
