Granite Yachilengedwe vs Mwala Wopanga (Mineral Casting)

Granite Yachilengedwe vs Mwala Wopanga (Mineral Casting):

Kusiyana zinayi zazikuluzikulu ndi kalozera pakusankha kupewa dzenje:

 

1. Tanthauzo ndi Mfundo Zopangira

Natural Black Granite

Mapangidwe: Mwachilengedwe amapangidwa ndi kusungunuka kwapang'onopang'ono kwa magma mkati mwa Dziko Lapansi's kutu. Zopangidwa makamaka ndi quartz, feldspar, ndi biotite, zokhala ndi mtundu wochokera ku mchere wakuda wa plagioclase kapena pyroxene.Mitundu yoyimira: China Jinan wakuda, India wakuda M10 (kachulukidwe 2.8-3.1g/cm³), miyala yamtengo wapatali (kachulukidwe 2.7-3g/cm³).

Cast Granite (Mineral Casting)

Mapangidwe: Chopangidwa ndi kusakaniza mchenga wa quartz, utomoni, ndi utoto, kenako ndikuwumbidwa pansi pa kutentha kwakukulu kapena kukakamizidwa kutengera mawonekedwe achilengedwe a granite.

Chiwerengero: 60-90% mchenga wa quartz + epoxy / polyester resin; alibe zomanga zachilengedwe zachilengedwe.

 

2. Kufananiza kwa Zinthu Zakuthupi ndi Zamankhwala

属性 (Katundu)	天然黑花岗岩 (Natural Black Granite)	人造花岗岩 (Cast Granite & mineral casting)
硬度 (Kuuma)	莫氏硬度 6–7，抗压强度 ≥200 MPa	莫氏硬度 4–5，抗压强度 80–120 MPa
密度 (Density)	2.63–3.1 g/cm³ (高密度)	2.2–2.5 g/cm³ (轻质)
酸/碱抗性 (Kukana kwa Acid/Alkali)	高度抗腐蚀(HCl中无腐蚀）	树脂在强酸/溶剂中降解
吸水率 (Kutenga madzi)	≤0.2% (适合户外使用）	0.5–1.2% (需防水处理）
热稳定性 (Thermal Stability)	低膨胀率(4.6×10⁻⁶/℃）	树脂在 >80℃ 时软化

 

3. Mapulogalamu ndi Kusanthula Mtengo

Natural Black Granite

Kugwiritsa Ntchito Bwino:

Kumanga Kwambiri: Zovala zakunja, zipilala (mwachitsanzo, miyala yamanda ya Shanxi Black yokhala ndi 110° kuwala).

Kugwiritsa Ntchito M'mafakitale: Maziko olondola a zida (kukhazikika kwapamwamba kwamafuta).

Mtengo: Mtengo wa mwala wovuta ndi wokwera kwambiri (wokhudzidwa ndi ukadaulo wosiyanasiyana komanso wokonza).

Cast Granite (Mineral Casting)

Kugwiritsa Ntchito Bwino:

Zokongoletsera Zam'nyumba: Zopangira zotsika mtengo, mapanelo a khoma (machitidwe osinthika).

Zosowa Zopepuka: Mipando, zokongoletsera zokongoletsera (30% zopepuka).

Mtengo: Mtengo wotsika kwambiri siwoyenera kuzinthu zamtundu umodzi (chuma chopanga kwambiri).

Chitetezo cha chilengedwe ndi kukhazikika.

 

4. Sustainability ndi Environmental Impact

Mwala Wachilengedwe: Kugwiritsa ntchito mphamvu zambiri mumigodi koma kutha kugwiritsidwanso ntchito (mwachitsanzo, kuphwanyidwa ngati kuphatikizika); ma radiation ochepa (sankhani Gulu A lovomerezeka).

Mwala Wopanga: Kutulutsa kwa VOC panthawi yopanga, koma zinyalala zimatha kubwezeredwa; palibe radioactiveizi.
