Cov hnab looj tes tiv thaiv kev txiav, hnab looj tes roj hmab, hnab looj tes tiv thaiv

Kev tiv thaiv kev ua haujlwm dai roj hmab hnab looj tes ua haujlwm li cas?
Cov txheej txheem tshwj xeeb khiav ntawm kev ua haujlwm tiv thaiv hnab looj tes dipping tshuab ntau lawm kab
1, preheat: tom qab ziab qhov cub, preheat cov cuab yeej sib tsoo rau 30 ℃ -40 ℃.
2, rau hauv pwm: phau ntawv rau hauv paj rwb sab hauv (pwm ntiv tes).
3, txias: khiav rau 1 feeb, qhov kub ntawm 30 ℃.
4, anti-thav duab: rau hauv cov txheej txheem tiv thaiv, tsis siv neeg tiv thaiv ncej (pwm ntiv tes)
5. Dipping: Nkag mus rau Dingqing roj hmab dipping tank, poob tag nrho cov dipping ncej vertically down, thiab ib nrab poob rau hauv 45 degrees rau 5 vib nas this.
6, poob: tom qab dipping kua nplaum rau hauv lub tank poob, txhawm rau kom cov khoom tuab, qhov hnyav sib xws, qhov poob qis yog nruab nrog lub tshuab tsis siv neeg vibration, lub sijhawm 20 vib nas this.Tag nrho lub sij hawm poob: (1) Raws li cov khoom thickness, hnyav, yuav tsum tau: (2) huab cua kub ntawm ib hnub, (3) viscosity ntawm cov kua nplaum, thiab lwm yam (siv cov kis tau tus mob los tswj qhov ceev ntawm lub roller chain)
7, qhuav thiab manic: mus rau hauv lub thawv kom qhuav (vulcanization), cov khoom siv roj ntsha hluav taws xob cua sov, lub thawv kom qhuav nrog lub kiv cua kom ua cua kub, kub tuaj yeem tswj tau.
Qhov ntsuas kub qis: kub 62 ℃ -98 ℃ sijhawm: 15 feeb, ntu nruab nrab: kub 92 ℃ -113 ℃ sijhawm: 20 feeb, qhov kub kub: kub 102 ℃ -168 ℃ sijhawm: 15 feeb, tag nrho cov cua sov lub sijhawm: 50 feeb.
8. Txias: Tom qab cov khoom yog vulcanized thiab qhuav, nws tawm ntawm qhov cub kom qhuav thiab nkag mus rau lub sijhawm txias ntawm cov khoom tiav rau 8 feeb.
9. Demoulding: Manually tshem cov hnab looj tes tiav.
10. Txias: Tom qab demoulding, cov pwm nkag mus rau hauv seem cua txias (cua txias), lub sij hawm yog 0.5 feeb, pwm kub yog 30-35 ℃.
Cov kab ntau lawm nkag mus rau hauv lub voj voog dua thaum kawg ntawm ib lub lis piam (tag nrho cov txheej txheem yuav siv li 80-90 feeb).
