Girazi rinopisa choto rinozivikanwawo segirazi tempering muchina, girazi tempering midziyo, girazi toughening muchina, etc. Inoshandisa muviri kana kemikari nzira kuumba press stress pamusoro girazi pamusoro uye tensile kushushikana kuumbwa mukati girazi layer.Kana girazi riri pasi pemasimba ekunze, iyo compressive stress layer inogona kudzikamisa chikamu chekushushikana kwekushushikana, kudzivirira kuputika kwegirazi, kuitira kuti uwane chinangwa chekuvandudza simba regirazi.Mukuwedzera, iyo microcracks pamusoro pegirazi inova yakanyanyisa pasi peiyi compressive stress, iyo inovandudzawo simba regirazi kune imwe nhanho.
Iyo yazvino yemuviri yakaomeswa nzira inoshandiswa zvakanyanya kupisa girazi kusvika pakupfava (650 ℃), girazi richiri kugona kuchengetedza chimiro chayo chepakutanga, asi ine humwe hunyanzvi hwekufambisa zvimedu mugirazi, kugadziridzwa kwechimiro, kuitira kuti kushushikana kwemukati kweiyo. kuvapo kwekubvisa munguva pfupi, wobva waisa girazi rinopisa chevira rekuomesa girazi rinofuridza, kana tembiricha yakadzikama, Iyo girazi repamusoro rinoburitsa kushushikana kwemukati, iyo yemukati layer inoburitsa tensile kushushikana, ndiko kuti, girazi rinogadzira yunifomu uye nguva dzose kugovera kwekushushikana kwemukati. , kunatsiridza kusimba kwekusimba kwegirazi sechinhu chinoputika, kuitira kuti girazi rirambe richikotama uye simba rekuita rivandudzwe.Panguva imwecheteyo, nekuda kwekuvapo kwekushushikana kweyunifomu mukati megirazi, kana girasi remunharaunda richinge yakuvadzwa nemhedzisiro inopfuura simba rayo, inoputika kuita zvidimbu zvidiki pasi pechiito chekushushikana kwemukati, izvo zvinovandudza kuchengetedzwa kwayo.Naizvozvo, girazi rakaomeswa rinogona zvakare kunzi prestressed girazi kana kuchengetedza girazi.
Mukuita kwegirazi rinopisa choto, kazhinji, mhepo uye kushushikana, mhepo iri mukati mekutonhora nekuda kwekusaenzana nekuda kwekusagadzikana kwegirazi kushushikana, iyo yakaumbwa mune imwe yakakosha Angle ichaona iyo girazi pamusoro ichionekwa pasi pechiedza uye rima uye chena. mitsetse.Stress spots dzinokonzereswawo nekusaenzana kwekushushikana, senge mukupisa, kune musiyano wetembiricha pakati pechoto chechoto uye pakati pekusagadzikana kwekunetseka.Stress spots haigone kudzivirirwa zvachose, asi yakanyatsogadzirwa michina yekupisa inogona kuderedza kuoneka kwenzvimbo dzekushushikana.
Zvinoenderana neaya ekudziya modhi maitiro emidziyo, iyo midziyo inogona kukamurwa kuita yekumanikidza convection kupisa tempered girazi tempering muchina uye nemwaranzi yekudziya girazi tempering choto;Kana iyo yakakamurwa zvinoenderana neyakapedzwa girazi chimiro, inogona kukamurwa kuita flat girazi tempering choto uye bend girazi tempering choto kana flat & bend girazi tempering choto.inoenderera mberi yekupisa midziyo, maviri-nzira yekudzikamisa michina, yakasanganiswa midziyo yekudziya, isina kuenzana arc bending midziyo yekudziya, choto chakarembera uye zvichingodaro.
Easttec girazi rinopisa choto, ine angangoita makore makumi matatu 'ruzivo, tekinoroji kubvira 1994.
