International Standard Silicon Hlau Qauv

Thoob ntiaj teb,silicon hlaucov qauv feem ntau yog cais raws li lawv cov tshuaj muaj pes tsawg leeg (tsuas yog silicon thiab hlau cov ntsiab lus). Cov qauv no tau txhais los ntawm cov koom haum sib txawv, feem ntau suav nrog cov hauv qab no:

Hauv Suav teb, cov qauv hlau silicon raug cais raws li cov ntsiab lus silicon, suav nrog tab sis tsis txwv rau:

Silicon hlau 1101: Silicon cov ntsiab lus yog li 99.79% (siab purity silicon).

Silicon hlau 2202: Silicon cov ntsiab lus yog hais txog 99.58% (cov ntsiab lus hlau siab, feem ntau yog siv hauv aluminium alloy ntau lawm).

Silicon hlau 3303: Silicon cov ntsiab lus yog kwv yees li 99.37% (cov ntsiab lus hlau ntau dua, tsim nyog rau cov nqi siv hluav taws xob).

Silicon hlau 553: Silicon cov ntsiab lus yog li ntawm 98.7%, cov ntsiab lus hlau yog li ntawm 5-6% (tus qauv ntau dua, haum rau ntau yam kev siv).

Thoob ntiaj teb, kev faib tawm ntawm silicon hlau feem ntau yog raws li ISO cov qauv, piv txwv li:

ISO 9001: Txawm hais tias ISO 9001 nws tus kheej tsis tsom cov tshuaj muaj pes tsawg leeg ntawm silicon hlau, nws ua kom muaj kev tswj hwm zoo ntawm cov khoom thiab muaj feem xyuam rau txhua yam khoom siv hlau silicon.

TS EN ISO 5725: Siv tau rau qhov raug thiab rov ua dua ntawm kev ntsuas thiab ntsuas, tab sis tsis qhia tshwj xeeb ntawm cov khoom siv ntawm silicon hlau.

Hauv Tebchaws Europe, cov qauv rau cov hlau silicon kuj zoo sib xws:

TS EN 12620: Feem ntau siv rau cov khoom siv hauv tsev, suav nrog kev siv cov hlau silicon, tab sis tsis qhia meej txog nws cov tshuaj muaj pes tsawg leeg.

TS EN 10088: Cov hlau tsis muaj steel thiab cov hlau alloys, suav nrog cov khoom siv uas muaj silicon, tab sis feem ntau yog tus qauv rau cov hlau alloys.

Cov qauv Asmeskas kuj tseem cuam tshuam cov kev cai rau cov hlau silicon:

ASTM A1005: Txuj rau ferrosilicon, uas qhia meej cov ntsiab lus ntawm silicon thiab hlau.

ASTM E30: Koom nrog cov txheej txheem thiab cov txheej txheem rau kev sim cov ntsiab lus silicon los xyuas kom meej tias cov hlau silicon zoo ua tau raws li qhov yuav tsum tau ua.

Japanese qauv muaj xws li:

JIS H 2100: suav nrog kev faib tawm thiab cov qauv ntawm cov xim hlau silicon, uas yog siv rau hauv ntau yam kev lag luam.

Cov hom ntawm Suav metallic silicon tuaj yeem raug suav hais tias yog:Silicon roj hmab 553, Silicon roj hmab 441, Silicon 421, Silicon roj hmab 411, Silicon roj hmab 521, Silicon 3303, Silicon 2202, lwm.

Kev xaiv ntawm cov hom no feem ntau yog ua raws li cov kev xav tau ntawm cov ntawv thov tiag tiag, xws li cov kev xav tau ntawm aluminium alloys lossis cov nqi txiav txim siab. Ntau hom silicon hlau muaj cov ntsiab lus sib txawv silicon thiab qib impurity, haum rau kev siv ntau yam.
