Heat soak test (HST)
Self-detonation of tempered glass
Girazi rakapfavaine chikanganiso chekuzvarwa che "self-detonation" - girazi rakadzikama mukushaikwa kwechiito chakananga chekunze uye chiitiko chakangoputsika.Mukati mekugadzirisa kugadzirisa, kuchengetedza, kutakura, kuisa, kushandiswa, nezvimwewo, girazi rinopisa rinoputika rinogona kuitika.Mazuvanogirazi rekuyangararamaitiro ekugadzira haagone kubvisa zvachose kuvepo kwe nickel sulfide (NiS) tsvina, saka kudziya-kuzviputira hakudzivisiki, inova inova hunhu hwegirazi rakatsamwa.Parizvino, hapana chiyero chenyika ipi neipi pasirese yekudzikamisa kuzviputira kwegirazi rakaomeswa.Zvinoenderana neruzivo rweindasitiri yegirazi yeChina, mwero wekuzviputira wega wega wakaomeswa girazi ungangoita 3 ~ 5 ‰.Kuti udzivise kuitika kwekuzviputika kwegirazi rakaomeswa rinoshandiswa mumapurojekiti akakosha nenzvimbo dzakakosha, bvunzo yekupisa inogona kutanga kuitwa.
Heat soak test inozivikanwawo sehomogeneous treatment, inowanzozivikanwa se "detonation".Girazi rakawanikwa rinonzi "detonation".girazi rinopisa rinopisa.Heat soak test ndeyekupisa iyogirazi rakadzikamakusvika 290 ℃ ± 10 ℃ mu "homogenizing furnace", uye ibatisise kwenguva yakati, kuitira kuti nickel sulfide (NiS) mugirazi yakadzikama inokurumidza kupedza crystal phase shanduko kuti ikurumidze kuwedzera kwayo, kuitira kuti iyo yakatanga kushandiswa. mushure mekunge girazi rakadzikama rinogona kuputika zvepamberi mufekitori "homogenizing furnace", Nokudaro kuderedza kushandiswa kwegirazi rinopisa mushure mekuisa self-detonation, kuwedzera kuchengeteka.Mushure mekupisa soak bvunzo, iyo yega-detonation mwero wehasha girazi inogona kudzikiswa kusvika kune imwechete mu10,000, asi kupisa soak bvunzo haigone kuvimbisa kuti girazi rakadzikama hariitike kuzvidzora, asi rinongoderedza kuitika kwekuzviputira. , uye inogadzirisa dambudziko rekuzviputira iro ratambudza mapato ese ari muchirongwa.Naizvozvo, kupisa soak bvunzo ndiyo inonyanya kushanda nzira yekugadzirisa dambudziko rekuzviputira pasi pezvino tekinoroji mamiriro anozivikanwa munyika.

Kudzikira kwega-detonation rate: Zvinoenderana nenhamba, iyo yega-detonation mwero yegirazi yakadziya ine kupisa soak bvunzo zvinoenderana nemaitiro inogona kudzikiswa kubva pa0.3% kusvika 0.01%, yakaderera zvakanyanya pane yekuzvibvisa-detonation mwero weyakajairwa girazi rine hasha.
