Toughened iav yog ib qho tseem ceeb ntawm chav da dej, qhov tseeb, yog ib yam ntawm cov iav prestressed, txhawm rau txhim kho lub zog ntawm iav, cov txheej txheem feem ntau siv hauv chemistry lossis physics, tsim rau ntawm cov iav iav hauv qab kev ntxhov siab. , thawj offset deg kev nyuaj siab quab yuam, thiaj li mus txhim kho cov kabmob muaj peev xwm ntawm cov iav reinforced, nws cov cua, txias thiab kub qhov cuam tshuam ntawm. Tom qab ntawd, kev siv tempered iav chav dej yog vim li cas nws tus kheej pom tseeb. Tam sim no peb yuav qhia koj txog qhov zoo thiab cov yam ntxwv ntawm tempered iav.
1 Lub ntsiab zoo:
thawj yog cov iav toughened dua li cov iav zoo tib yam muaj zog ntau zaus, khoov lub zog yog 3 ~ 5 npaug ntawm cov iav zoo tib yam, cuam tshuam lub zog yog 5 ~ 10 npaug ntawm cov iav zoo tib yam, tib lub sij hawm nce lub zog los txhim kho kev ruaj ntseg. Qhov thib ob yog kev siv kev nyab xeeb, nws lub peev xwm nqa tau nce ntxiv los txhim kho qhov tsis yooj yim, txawm tias cov iav tempered puas yuav tsis muaj lub kaum sab xis, qhov kev puas tsuaj rau tib neeg lub cev yog txo qis heev. Lub iav tempered tsis kam mus rau 2 ~ 3 zaug los txhim kho cov khoom thermal dua li iav zoo tib yam, tuaj yeem tiv taus qhov kub thiab txias ntawm ntau tshaj 150LC. Txhawm rau tiv thaiv thermal breakage muaj txiaj ntsig zoo.
2. Tempered iav nta:
(1) lub zog: tom qab tempering, lub zog txhua yam, kev cuam tshuam thiab khoov lub zog ntawm lub khob tuaj yeem ncav cuag 4 - 5 npaug ntawm cov iav zoo tib yam.
(2) thermal stability txhim khu kev qha: toughened iav tuaj yeem tiv taus qhov kub thiab txias qhov sib txawv yam tsis muaj kev puas tsuaj, tiv taus qhov kub thiab txias muaj peev xwm yog 3 npaug ntau dua li cov iav ntab iav ntawm tib lub thickness.
(3) txhim kho kev nyab xeeb ntawm tempered iav los ntawm lub zog tom qab kev puas tsuaj, sai sai pom cov khoom me me obtuse, thiaj li ua kom muaj kev nyab xeeb ntawm tus kheej.
