Txoj kev rau kev tsim pob tshab cov khoom lag luam marble

Nyob rau tam sim no, cov khoom neeg tsim marble yog tsim nrog cob. Txawm hais tias cov khoom yog qhov teeb meem sib kis, cov ntsiab lus ntawm cov tawv muaj ntau txog 30%, uas ua rau cov khoom lag luam yooj yim rau kev deform, khoov thiab muaj hnub nyoog thaum siv. Qhov kub tiv taus kub ntawm qhov khoom yog li 40 ° C, uas cuam tshuam rau lub neej kev pab. Yog li ntawd, kev ntxhib los mos thiab kev ntxhib los mos ntawm ntuj pob zeb tsis tuaj yeem pom. Lub tswv yim no muab lub teeb xa cov ntoo dag uas muaj lub siab sim thiab tuaj yeem tsim cov khoom siv hluav taws xob thiab cov txheej txheem tsim tawm ntawd.

Tus txhais lus dag marble, raws li huab hwm coj piv, cov khoom siv yog 5-100 ntxaij dawb pob zeb diamond siv lead ua los yog rosin jade hmoov xuab zeb yog 500-700, ultra-nplua calcium carbonate hmoov yog 30-180, thiab pob tshab cov roj hmab tsis muaj ntxig polyester cob yog 58 -150, Qhov pib tsim yog 0.9 1.8, tus ntsuas nrawm yog 0.06-0.08, cov xim yog 0.01-1.5, thiab pob tshab nano-SiOz ~ cov khoom siv yog 30-50.

Ultra-nplua calcium carbonate hmoov yog calcium carbonate hmoov saum toj no 1250 mesh, pob tshab polyester cob tsis zoo siv cov khoom siv roj hmab siv roj hmab, tus pib siv ketone initiator, accelerator siv cobalt accelerator, thiab xim siv titanium dioxide, hlau daj, thiab lwm yam.

Cov theem tsim khoom ntawm cov pob zeb ci dag translucent muaj raws li hauv qab no:

1. Cov khoom xyaw: do 5 txog 100 mesh dawb pob zeb diamond siv lead ua los yog rosin jade hmoov xuab zeb thiab ultra-nplua calcium carbonate hmoov kom tau sib xyaw A;

2, ntxiv cov xim ntxiv rau qhov sib tov A thiab do rau 5 txog 2O feeb kom tau txais qhov sib tov B;

3, ntxiv cov pob tshab tsis muaj ntxig polyester cob, pib thiab kev nrawm rau kev sib xyaw B, sib tov thiab do, tom qab ntawd nqus tsev, qhov nqus tsev kawm ntawv yog 60 70cmHg, txuas ntxiv mus do kom txog thaum cov khoom ua agglomerate, kom tau txais cov sib xyaw C;

4. Ntxiv cov pob tshab nano SiO pob tshab rau cov khoom sib xyaw C, do, thiab muab cov khoom tso rau hauv cov pwm tom qab nqus;

5. Tso qhov txhaj tshuaj pwm tso rau hauv chav nqus tsev, ua kom muaj zog thiab siv siab, thiab daim ntawv;

6, demoulding tom qab kho, kho lub sijhawm ≥ teev, kho rau 6 hnub tom qab demolding:

7. Raws li cov ntsiab lus tshwj xeeb, txiav, txhuam thiab ua kom tiav cov khoom siv pob zeb los ua kom tau lub teeb kis cov duab ntxoo.
