Tau Lead Tawm: Yuav Ua Li Cas Ntxuav Graphite Stains
- lwv nws! Yog lawm, sim cov lwv.
- Liquid Detergent. Yog hais tias ib tug mos lwj tsis tshem tawm cov stain, siv ob peb tee ntawm cov kua xab npum rau ntawm qhov chaw uas muaj kev cuam tshuam thiab maj mam txhuam nrog ib daim ntaub mos, ntub dej.
- Txhua Lub Hom Phiaj Cleaner.
- Zaub roj.
- Cov ntaub so menyuam mos.
- Tshuaj txhuam hniav.
Kuj Paub, ntau npaum li cas yog graphite hmoov? Nqe
| Hom Natural Graphite | Tus nqi nruab nrab ($/tonne Lub Ib Hlis 2013 |
|---|---|
| Medium Flake (95% - 98%) | $1, 050 – $1, 400 |
| Loj Flake (95% - 98%) | $1, 400 – $1, 800 |
| Jumbo Flake (95% - 98%) | >$1, 600 |
| Roj teeb Qib Flake (99.9%) | $5, 000 – $20, 000 |
Kuj tseem paub, graphite hmoov yog dab tsi?
Graphite Raws li ib tug sub-hlau, yog muab los ntawm cov pob zeb carbon uas yog metamorphosed. Nws yog muab los ntawm daim ntawv flaky los ntawm cov pob zeb no. Nws yog ib qho ntawm cov hlau softest, thiab yog carbon nyob rau hauv nws daim ntawv ruaj khov. Nws yog ib tug zoo conductor ntawm hluav taws xob thiab kuj ua ib tug zoo lubricant. Cov hmoov kuj yog tsim los ntawm kev siv dua tshiab graphite.
Puas yog graphite hmoov lom?
Inhalation Toxicity : Graphite ib leeg tuaj yeem ua rau khaus ntawm txoj hlab ntsws tab sis tsis tau teev tseg tias yog cov carcinogen. Txawm li cas los xij, nws yuav muaj cov impurities ntawm crystalline silica uas tau teev tseg tias yog carcinogen. Kev nqus cov plua plav dhau lub sijhawm ntev tuaj yeem ua rau mob pneumoconiosis.

Yuav ua li cas koj ua pob zeb diamond los ntawm graphite?
Ib txoj hauv kev los tig graphite rau hauv pob zeb diamond yog los ntawm kev siv lub siab. Txawm li cas los xij, txij li graphite yog daim ntawv ruaj khov tshaj plaws ntawm cov pa roj carbon monoxide nyob rau hauv ib txwm muaj, nws yuav siv li 150,000 npaug ntawm huab cua siab ntawm lub ntiaj teb saum npoo los ua li ntawd. Tam sim no, lwm txoj hauv kev uas ua haujlwm ntawm nanoscale yog nyob rau hauv tuav
Yuav ua li cas tiv thaiv ib tug dwarf dawb los ntawm tsoo mus rau lub qhov dub?
Lub hnub qub dwarf dawb yuav raug tso tseg los ntawm kev tawg txuas ntxiv vim qhov tsis txaus loj uas qhib qhov rooj rau Electron Degeneracy los ua nws txoj haujlwm. Nws yog hu ua Neutron degeneracy siab. Yog li ntawd, lub hnub qub neutron yuav tsis txuas ntxiv mus ua ib lub qhov dub
Yuav ua li cas yog tias ob lub hnub qub sib tsoo?
Thaum ob lub hnub qub neutron orbit ib leeg ze, lawv muab kauv sab hauv raws li lub sij hawm dhau mus vim muaj hluav taws xob gravitational. Thaum lawv sib ntsib, lawv txoj kev sib koom ua ke ua rau muaj qhov hnyav dua neutron lub hnub qub lossis lub qhov dub, nyob ntawm seb qhov loj ntawm cov seem tshaj qhov txwv Tolman-Oppenheimer-Volkoff
Yuav ua li cas koj thiaj paub yog tias ib yam khoom tsoo hauv av?
VIDEO Tsis tas li ntawd, yuav ua li cas thaum ib yam khoom tsoo hauv av? Thaum lub yam khoom tsoo hauv av , lub zog kinetic yuav tsum mus rau qhov chaw, vim hais tias lub zog tsis yog tsim los yog puas, tsuas yog pauv mus. Yog hais tias kev sib tsoo yog elastic, lub ntsiab lus khoom tuaj yeem bounce, ntau lub zog nkag mus rau hauv ua kom nws rov qab los dua.
Yuav ua li cas yog tias koj nqus tau graphite?
Kev raug cov graphite plua plav ntau dhau ntawm lub sijhawm ntev tuaj yeem ua rau mob ntev thiab mob hnyav dua hu ua Graphitosis, uas yog ib hom kab mob pneumoconiosis.Qhov mob no tshwm sim thaum nqus tau cov khoom ntawm graphite khaws cia hauv lub ntsws thiab bronchi
