Yuav ua li cas qhia qhov zoo ntawm tempered iav vaj huam sib luag yog qhov zoo lossis tsis zoo
Tempered iav (iav iav) yog tsim los ntawm cov iav cua sov rau hauv qab no tsuas yog qhov chaw yaj (ib ncig 650 ℃) thiab tom qab ntawd txias txias nws. Ua li no, kev ntxhov siab ntawm cov iav ntawm cov iav nto yog tsim thiab lub zog ntawm iav yog 4 txog 5 npaug zog dua li cov iav niaj hnub niaj hnub.
Rau tiav lawm tempered iav panels, yuav ua li cas qhia nws qhov zoo yog qhov zoo lossis tsis?
a.Cov Khoom Siv: Cov ntaub ntawv zoo zoo ntab iav cov ntaub ntawv muaj cov xim pom tseeb dua thiab yuav tsis pom muaj npuas, muaj cov khoom tsis haum, tsis tshua muaj npib tsib xee sulphide suav nrog. Nickel sulphide yog qhov tseem ceeb uas ua rau lub qhov khoob tawg ntawm cov iav tawg ntau dua.
b. Tom qab iav yog tempered, npoo polished zoo li ci ntxiab, du, thiab zoo zoo. Raws li peb txhua tus paub, txhua qhov chaw da dej qhov rooj ntawm qhov ntau thiab tsawg yuav tsum muaj qhov ci ntsa iab polished.
c.Tsis tas li ntawd, lub tiaj ntawm lub vaj huam sib luag li qub muaj ntau yam zoo dua thiab kev kho qhov muag deformation yog qhov tsawg dua.
d.Lub pits tshwm sim los ntawm kev npau taws kuj tsis tshua muaj tshwm sim.
e. Chaw punch fragmentation kuaj kuj tuaj yeem ua rau kom qhia txog qhov ua kom npau taws. Tab sis tom qab xuas nrig ntaus, cov iav vaj huam sib luag yuav tawg mus rau hauv cov lus tsis zoo thiab tsis tuaj yeem siv tau lawm.
Hauv qab no yog yuav ua li cas ua qhov kev ntsuas raws li ANSI Z97.1 2015.
(1) Qhov hnyav tag nrho ntawm kaum (10) qhov loj tshaj plaws uas tsis muaj qhov sib tsoo yuav tsum tsis hnyav tshaj qhov hnyav ntawm 10 square inches (6452 mm2) ntawm cov qauv ntsuas thawj zaug. (Qhov hnyav hauv ooj ntawm 10 square inches ntawm iav yog sib npaug li 14,5 npaug ntawm lub khob tuab hauv nti. Qhov hnyav hauv grams 10 square inches ntawm iav yog sib npaug rau 412 npaug ntawm lub khob tuab hauv nti (16.18 grams / mm)).
(2) Tsis muaj ib qho me me yuav tsum ntev tshaj 4 ntiv tes (102 hli) tsis suav thaj tsam ntawm lub vojvoog 4 ntiv tes (102 hli) npuab rau ntawm qhov cuam tshuam, thiab ciam teb ntawm 1 nti (25 mm) ncig thaj tsam ib puag ncig / ntug ntawm qhov ntsuas pov tseg. Cov.
