Piav qhia meej txog cov kev qhia tshwj xeeb ntawm cov kav dej uas siv tooj liab hauv cov tub yees txias
Cov raj tooj liab tau siv dav hauv cov tshuab tub yees. Cov raj tooj liab yog siv rau hauv kev sib txuas cov raj, cov khoom siv hluav taws xob sib txuas, cov raj capillary, thiab lwm yam. Txawm li cas los xij, cov khoom siv ntawm cov raj tooj liab kuj txawv. Feem ntau, feem ntau siv tooj liab raj hauv lub tshuab tub yees yog tooj liab qib TP2M. , lwm hom kuj siv.
1. Lub hom, raws li txoj cai thiab specifications ntawm cov khoom yuav tsum ua raws li cov kev cai ntawm Table 1:

Piv txwv:
Round raj ua los ntawm TP2, nyob rau hauv ib tug mos mos lub xeev, nrog ib tug txheej txoj kab uas hla ntawm 4.76MM thiab ib phab ntsa thickness ntawm 0.5 hli yog cim: tube TP2M φ4.76 × 0.5 GB / T { {10}}
2. Cov ntaub ntawv tsom xam
Cov tshuaj muaj pes tsawg leeg ntawm cov yeeb nkab yuav tsum ua raws li cov kev cai ntawm cov qib sib thooj hauv GB / T 5231 tus qauv.
T2 yog tooj liab ntshiab, thiab TP1 thiab TP2 yog phosphorus-deoxidized tooj liab.
Cov kev cai tshwj xeeb hauv qab no tau ua rau cov tshuaj muaj pes tsawg leeg ntawm T2: Cu + Ag Ntau dua lossis sib npaug li 99.90%. Lwm cov khoom xyaw yog raws li GB 5231.
Cov kev cai tshwj xeeb hauv qab no yog tsim rau cov tshuaj muaj pes tsawg leeg ntawm TP1: Cu + Ag Ntau dua lossis sib npaug rau 99.90%, P yog 0.004% ~ 0.012%. Lwm cov khoom xyaw yog raws li GB 5231.
Cov kev cai tshwj xeeb hauv qab no yog tsim rau cov tshuaj muaj pes tsawg leeg ntawm TP2: Cu + Ag Ntau dua lossis sib npaug rau 99.9%, P yog 0.015% ~ 0.040%. Lwm cov khoom xyaw tau teev tseg hauv GB / T 5231.
3. Dimensions thiab loj kam rau ua

4. Mechanical zog
Chav tsev kub txhua yam khoom ntawm cov yeeb nkab yuav tsum ua raws li cov cai hauv Table 3.

5. Kev suav ntawm metric hnyav
Txoj Kev 1: Yog tias tus qauv qis dua 1000mm, coj cov yeeb nkab tooj liab nrog qhov ntev ntawm 200mm ± 10mm thiab zom ob qhov chaw nres nkoj. Cov chaw nres nkoj yuav tsum tau nyob rau ntawm lub axis thiab tsis muaj shrinkage. Siv lub vernier caliper los ntsuas qhov ntev, ntsuas nws nrog qhov sib npaug nrog qhov tseeb ntawm 1 mg, thiab suav qhov hnyav rau ib chav tsev ntev, uas yog qhov hnyav ntawm ib metres.
Kev suav cov mis: Gram hnyav=ntev / hnyav * 1000
Txoj Kev 2: Yog tias qhov hnyav ntawm daim duab xav tau, siv qhov ntsuas nrog qhov tseeb ntawm 0.1g los ntsuas nws.
