Birta leh dhumucdiisuna waxay ka yar tahay 5mm tuubo ha samayn tijaabo adag

Shuruudaha Imtixaanka

Tijaabada Haydarooliga
Tijaabada Haydarooliga waa in lagu sameeyaa tuubooyinka birta mid mid. Cadaadiska ugu badan ee tijaabada waa 20 MPa. Cadaadiska tijaabada, wakhtiga xasilinta waa inuusan ka yarayn 10 s, iyo daadinta tuubada birta lama ogola.
Tijaabada fidsan
Tijaabada fidinta waa in lagu sameeyaa tuubo bir ah oo dhexroorka ka weyn tahay 22 mm
Tijaabada ololaysa
Birta qaab dhismeedka kaarboon tayo sare leh iyo tuubooyinka birta ah ee aan lahayn (kulka u adkaysta) ee leh dhexroorka dibadda oo aan ka badnayn 76 mm iyo dhumucdiisuna aanay ka badnayn 8 mm waa in lagu tijaabiyaa balaarin. Tijaabada ololka waa in lagu sameeyaa heerkulka qolka. Dhererka dhexroorka dibadda ee muunada ka dib taper xudunta sare waa 60% ee ololaysa waa in ay buuxisaa shuruudaha miiska 7. Ma jiro dildilaacyo ama dildilaaca on muunada ka dib ololaya. Marka loo eego shuruudaha dalbadaha oo lagu xusay qandaraaska, birta qaab dhismeedka alloy sidoo kale waxaa loo isticmaali karaa ballaarinta tijaabada.
xiniinyo aan burburin
Tuubooyinka birta ah waa in ay hoos yimaadaan ogaanshaha cilladda ultrasonic mid mid si waafaqsan xeerarka GB / T 5777-2008. Marka loo eego shuruudaha dalbadaha, tijaabooyin kale oo aan burburin ayaa lagu dari karaa ka dib markii ay wada xaajoodaan alaab-qeybiyaha iyo alaab-qeybiyaha oo lagu tilmaamo qandaraaska.
Baaritaanka daxalka intergranular
Tijaabada daxalka intergranular waa in lagu sameeyaa tuubooyinka birta ah ee aan lahayn (kulka u adkaysta). Habka imtixaanku waa inuu waafaqsan yahay qodobada habka Shiinaha E ee GB / T 4334-2008, iyo u janjeersiga daxalka intergranular lama ogola ka dib imtixaanka.
Ka dib markii ay wada xaajoodaan alaab-qeybiyaha iyo alaab-qeybiyaha, oo lagu xusay heshiiska, dalbadeeyuhu wuxuu magacaabi karaa hababka kale ee baaritaanka daxalka.
