YINSHAN 42.5 Zoo tshaj plaws rau sulphoaliminate cement 42.5 / Low Alkalinity Cement
Daim Ntawv Thov
Cov cement dawb CSA yog cov cement tshwj xeeb Calcium Sulfo Aluminate (CSA) uas tsim los rau cov pob zeb kho kom zoo nkauj, terrazzo, pem teb, iav fiber reinforced concrete (GFRC), cov mortars qhuav, cov grout tsis ntsws, fiber cement thiab ntau ntxiv. Cov khoom siv raw khoom ntshiab tshwj xeeb, kev ua kom zoo calcination thiab kev sib tsoo saib xyuas zoo lav qhov xim dawb sib xws.
Cov Khoom Muaj Ntawv Pov Thawj Tsim Tawm raws li GB / T 19001-2008 IDT ISO9001: 2008 Kev Tswj Xyuas Kev Zoo.

Cov txiaj ntsig
1. Kev teeb tsa sai, Kev tawv sai, lub zog siab; 4 teev compressive zog tuaj yeem ncav cuag 15 Mpa, 43 Mpa tom qab 28d, tsim nyog los ua cov khoom muaj zog siab.
2. Kev nthuav dav me me, qhov qhuav me me, qhov ntev hloov me me heev. Qhov qhuav me me tsuas yog 1/10 ntawm Portlandcement.
3. Muaj cov khoom tiv thaiv xeb zoo heev hauv sulfate, chloride, magnesium ntsev thiab dej hiav txwv. Kev tiv thaiv xeb.
coefficient ntawm kev sib txhuam > 1.
4. Kev nkag tsis tau zoo, qhov siab permeation yog 1/5 ntawm Portland cement.
5. Cov khoom tiv taus khov siab, tuaj yeem tau txais lub zog ntawm qhov hnyav ntawm qhov txias hauv 2 teev ~ 3 teev.
6. Kev tso cua sov tsawg
7. Tus nqi PH yog qis dua 10.0 rau cov khoom GRC.
9. Kev ua haujlwm tiv taus whiskering zoo10. Muaj peev xwm sib tov nrog Portland cement hauv qhov sib piv kom raug, tuaj yeem txo qhov kev ntswj ntawm Portland cement, txo cov kab nrib pleb.
Cov haujlwm tsim nyog suav nrog
1.GRC
2. Cov tshuaj txhuam kho kom zoo nkauj
3. Cov tshuaj pleev rau phab ntsa sab hauv thiab sab nraud4. Cov khoom siv sab hauv tsev thiab sab nraum zoov
5. Cov tshuaj nplaum uas ua los ntawm cov cement
6. Pob zeb dag thiab pem teb
7. Txheej nyias nyias ntawm kev kho cov pob zeb thiab cov khoom siv sib dhos ua ke
8. Cov tshuaj nplaum uas tawg tsis pub tawg
9. Cov tshuaj nplaum sab nraud uas ua rau cov khoom rwb thaiv tsev, cov tshuaj nplaum sib txuas thiab cov nplaum pobzeb
10. Cov pob zeb zoo nkauj
11. Cov pob zeb ua tiav lawm
12. Kev txhawb nqa tsev
13. Lub zog siab thaum ntxov tsis yog cov grouts ntsws
14. Cov khoom siv tsis muaj dej thiab ntsaws
Xoom rau Qis Shrinkage
Cov cement CSA muaj zog dua thaum ntxov dua li cov cement portland uas ua rau cov pob zeb tsis ntsws thiab cov khoom siv mortar uas tsis ntsws thiab tsis ntsws. Cov cement CSA siv yuav luag 100% ntawm cov dej sib tov thaum lub sijhawm ua kom dej noo, ua rau muaj dej me ntsis los pab txhawb rau kev ntsws. Qhov kub ntawm cov dej noo qis dua li cov txheej txheem teeb tsa sai sib piv. Tsis tas li ntawd, vim muaj zog thaum ntxov, me ntsis lossis tsis muaj kev ntsws tom qab teeb tsa thawj zaug.
