Granite Ntuj vs granite dag (Mineral Casting)

Granite Ntuj vs granite dag (Mineral Casting):

Plaub qhov sib txawv tseem ceeb thiab phau ntawv qhia rau kev xaiv qhov tsis txhob khawb:

 

1. Cov Lus Txhais thiab Cov Ntsiab Cai ntawm Kev Tsim

Granite Dub Ntuj

Kev Tsim: Tsim los ntawm kev siv zog qeeb ntawm magma tob hauv ntiaj teb's crust. Ua los ntawm quartz, feldspar, thiab biotite, nrog rau xim los ntawm cov minerals plagioclase tsaus lossis pyroxene.Cov hom sawv cev: Tuam Tshoj Jinan dub, Is Nrias teb dub M10 (qhov ceev 2.8-3.1g / cm³), lwm yam granite (qhov ceev 2.7-3g / cm³).

Cast Granite (Mineral Casting)

Kev Tsim: Ib yam khoom siv hluavtaws ua los ntawm kev sib xyaw cov xuab zeb quartz, cov resin, thiab cov xim, tom qab ntawd pwm hauv qab qhov kub siab lossis siab kom ua raws li cov qauv granite ntuj.

Cov khoom xyaw: 60–90% xuab zeb quartz + epoxy/polyester resin; tsis muaj cov qauv minerals ntuj.

 

2. Kev Sib Piv Cov Khoom Siv Lub Cev Thiab Tshuaj

属性 (Property)	Ntuj Dub Granite	Granite Casting thiab ntxhia pob zeb Castings
Hardness	6-7, 抗压强度 ≥200 MPa	4-5, 抗压强度 80-120 MPa
密度 (Density)	2.63-3.1 g / cm³	2.2-2.5 g / cm³ (Qhov siab)
酸/碱抗性 (Acid/Alkali Resistance)	高度抗腐蚀 (HCl中无腐蚀)	树脂在强酸/溶剂中降解
吸水率 (Water Absorption)	≤ 0.2%	0.5-1.2%
Thermal Stability	4.6 × 10⁻⁶ / ℃	Kub kub> 80 ℃

 

3. Cov Ntawv Thov thiab Kev Tshuaj Xyuas Tus Nqi

Granite Dub Ntuj

Kev Siv Zoo Tshaj Plaws:

Kev Tsim Kho Zoo Tshaj Plaws: Sab nraud cladding, monuments (piv txwv li, Shanxi Black tombstones nrog 110° ci ntsa iab).

Kev Siv Hauv Kev Lag Luam: Cov khoom siv precision (kev ruaj khov thermal zoo dua).

Tus nqi: Tus nqi ntawm cov pob zeb ntxhib yog qhov siab heev (cuam tshuam los ntawm ntau yam thiab kev siv tshuab ua).

Cast Granite (Mineral Casting)

Kev Siv Zoo Tshaj Plaws:

Kho Kom Zoo Nkauj Sab Hauv Tsev: Cov txee ua haujlwm pheej yig, cov vaj huam sib luag phab ntsa (cov qauv hloov kho tau).

Cov Kev Xav Tau Sib Dua: Rooj tog, cov khoom dai kom zoo nkauj (sib dua 30%).

Tus nqi: Tus nqi qis tsis haum rau cov khoom ib qho tshwj xeeb (kev lag luam tsim khoom siab).

Kev tiv thaiv ib puag ncig thiab kev ruaj khov.

 

4. Kev Ruaj Ntseg thiab Kev Cuam Tshuam rau Ib puag ncig

Pob Zeb Ntuj: Siv zog ntau heev rau kev khawb av tab sis rov ua dua tshiab (piv txwv li, tsoo ua cov pob zeb sib xyaw); tsawg kawg nkaus kev tawm hluav taws xob (xaiv Chav Kawm A tau ntawv pov thawj).

Pob Zeb Ua Los Ntawm Khoom Siv: Cov pa phem VOC thaum lub sijhawm tsim khoom, tab sis pov tseg cov khoom siv rov ua dua tshiab; tsis muaj radioactivity.
