Kev ruaj ntseg glazing cov ntaub ntawv nyob rau hauv lub tsev - Ntu 2: Tempered iav

1 Scope

Qhov no ntawm GB 15763 qhia txog kev faib tawm, kev xav tau, kev sim thiab kev soj ntsuam cov cai ntawm tempered iav rau cov tsev tsim los ntawm cov txheej txheem kho cua sov.

Ib feem ntawm GB 15763 no siv tau rau cov iav tempered rau cov tsev tsim los ntawm cov txheej txheem kho cua sov. Rau cov iav tempered siv sab nraum kev tsim kho (xws li cov khoom siv hauv tsev, rooj tog zaum, thiab lwm yam), yog tias tsis muaj cov qauv khoom sib xws, cov qauv no tuaj yeem siv raws li nws cov yam ntxwv ntawm cov khoom.

2 Normative cov ntaub ntawv

Cov nqe lus hauv cov ntaub ntawv hauv qab no dhau los ua cov ntsiab lus ntawm ntu no los ntawm kev siv hauv ntu no. Rau cov ntawv sau hnub tim, tag nrho cov kev hloov kho tom ntej (tsis suav nrog cov ntsiab lus tsis raug) lossis kev hloov kho tsis siv rau tus qauv no. Txawm li cas los xij, ob tog rau kev pom zoo raws li nqe lus no raug txhawb kom kawm seb qhov tseeb versions ntawm cov ntaub ntawv no tuaj yeem siv tau, rau cov ntaub ntawv tsis raug cai, qhov tseeb version siv rau ntu no.

3 Kev txhais thiab kev faib tawm

3.1 Kev txhais

Tempered iav: iav tom qab kev kho cua sov. Nws yog tus cwj pwm hauv cov txheej txheem kev ntxhov siab yog tsim rau ntawm iav nto, lub zog txhua yam thiab thermal shock kuj tau txhim kho, thiab nws muaj lub xeev tshwj xeeb tawg.

3.2 Kev faib tawm

3.2.1 Raws li cov txheej txheem tsim khoom, tempered iav tuaj yeem muab faib ua:

Vertical tempered iav: Tempered iav tsim los ntawm dai nrog clamps thaum lub sij hawm tempering txheej txheem.

Kab rov tav tempered iav: Tempered iav tsim los ntawm kab rov tav cov menyuam txhawb nqa thaum lub sijhawm tempering.

3.2.2 Tempered iav yog cais los ntawm cov duab rau hauv tempered iav thiab nkhaus tempered iav.

4 iav siv hauv tempered iav

Qhov zoo ntawm cov iav siv hauv kev tsim cov iav tempered yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov qauv khoom sib xws. Rau cov iav siv hauv kev tsim cov iav tempered nrog cov kev cai tshwj xeeb, qhov zoo ntawm iav yuav tsum tau txiav txim los ntawm ob tus neeg muag khoom thiab tus neeg yuav khoom.

5 Kev xav tau

Cov khoom thiab cov qauv kev sim ntawm tempered iav yuav tsum ua raws li cov kev cai ntawm cov khoom sib xws hauv Table 1. Ntawm lawv, kev ua haujlwm kev nyab xeeb yog qhov yuav tsum tau ua.
