Mtengo Wabwino Wopanga Potaziyamu Hydroxide CAS:1310-58-3
Potaziyamu Hydroxide: Potaziyamu hydroxide (mankhwala a chemical formula :KOH, kuchuluka kwa fomula :56.11) ufa woyera kapena flake solid. Malo osungunuka ndi 360~406℃, malo owira ndi 1320~1324℃, kuchuluka kwa relative density ndi 2.044g/cm, malo owunikira ndi 52°F, refractive index ndi N20 /D1.421, nthunzi kuthamanga ndi 1mmHg(719℃). Alkaline wamphamvu komanso wowononga. N'zosavuta kuyamwa chinyezi mumlengalenga ndi deliquescence, ndikuyamwa carbon dioxide mu potassium carbonate. Sungunuka mu pafupifupi magawo 0.6 a madzi otentha, magawo 0.9 a madzi ozizira, magawo atatu a ethanol ndi magawo 2.5 a glycerol. Ikasungunuka m'madzi, mowa, kapena ikachiritsidwa ndi asidi, kutentha kwakukulu kumapangidwa. pH ya 0.1mol/L yankho inali 13.5. Poizoni wapakati, mlingo wapakati wakupha (makoswe, pakamwa) 1230mg/kg. Amasungunuka mu ethanol, amasungunuka pang'ono mu ether. Ndi amchere kwambiri komanso amawononga zinthu.

Wopanga Mtengo Wabwino CalciumAlumina Simenti CAS:65997-16-2
CalciumAlumina Simenti ndi simenti yokhala ndi calcium calcium kapena calcium aluminiyamu ngati gawo lalikulu la mchere. Imapangidwa ndi aluminiyamu yachilengedwe kapena aluminiyamu yamakampani ndi calcium carbonate (mwala wa laimu) molingana ndi gawo linalake, lomwe limapangidwa poyatsa kapena kusungunuka ndi magetsi.
Zosakaniza ndi magulu: CalciumAlumina Simenti ikhoza kugawidwa m'magulu awiri: aluminiyamu wamba calcium calcium simenti (al2O3 53-72%, CAO 21-35%) ndi aluminiyamu yoyera calcium simenti (al2O3 72-82%, CAO 19-23%). Magulu awiri: Simenti ya aluminiyamu wamba ikhoza kugawidwa m'magulu awiri: low-iron type (FE2O3 <2%) ndi high-speed rail type (Fe2O37-16%). low-rail aluminium calcium simenti ikhoza kugawidwa m'magulu awiri: alum soil simenti (Al2O353 ~ 56%, CAO 33-35%), aluminiyamu -60 simenti (al2O359%to 61%, CAO 27-31%), ndi low-calcium aluminium acid simenti (Al2O3 65-70%, CAO 21 to 24%). Simenti ya calcium yopangidwa ndi aluminiyamu yokha ingagawidwe m'magulu awiri: Al2O3 72-78%) ndi mtundu wa aluminiyamu wopangidwa ndi aluminiyamu wokwera kwambiri (Al2O3 78-85%). Kuphatikiza apo, pali simenti ya calcium yolimba komanso yofulumira yoyambirira ya aluminiyamu.CAS: 65997-16-2

Mtengo Wabwino Wopanga Stearic acid CAS:57-11-4
Stearic acid: (mtundu wa mafakitale) Octadecanoic acid, C18H36O2, imapangidwa ndi hydrolysis ya mafuta ndipo imagwiritsidwa ntchito kwambiri popanga stearate.
Stearic Acid-829 Stearic acid, Stearic acid ndi mafuta olimba ochokera ku mafuta a nyama ndi ndiwo zamasamba, omwe zigawo zake zazikulu ndi stearic acid (C18H36O2) ndi palmitic acid (C16H32O2).
Chogulitsachi ndi choyera kapena choyera ngati ufa kapena kristalo wolimba, mawonekedwe ake ali ndi kristalo wonyezimira pang'ono wa singano; Chili ndi fungo lochepa lofanana ndi mafuta ndipo sichikoma. Chogulitsachi chimasungunuka mu chloroform kapena diethyl ether, chimasungunuka mu ethanol, sichisungunuka m'madzi. Malo oundana Malo oundana (Appendix Ⅵ D) a chinthuchi sayenera kutsika kuposa 54℃. Mtengo wa ayodini Mtengo wa ayodini wa chinthuchi (Appendix Ⅶ H) supitirira 4. Mtengo wa Asidi (Appendix Ⅶ H) wa chinthuchi umayambira pa 203 mpaka 210. Stearate imakumana mosavuta ndi ma magnesium ndi calcium ions kuti ipange magnesium stearate ndi calcium stearate (white precipitate).
