Okusayidi nthaka. Katundu ndi Mapulogalamu

Nthaka okusayidi (dzina lina - nthaka okusayidi) - ndi munthu okusayidi amphoteric, crystalline colorless ufa chikasu pa Kutentha pang'onopang'ono komanso sublimating pa madigiri 1800. Insoluble madzi. The makutidwe ndi okosijeni nthaka mu mankhwala - 2. The mankhwala chilinganizo ZnO. Nkhanizi ndi zofunika kwa anthu. Iwo ali zotsatira m'zigawozigawo pa thupi la munthu.

okusayidi nthaka: katundu thupi

1. The madutsidwe matenthedwe ndi 54 W / (m * K).
2. Ndi michenga yopangira zida zamagetsi ndi gulu m'lifupi mwake 3.3 EV.

Chemical katundu wa okusayidi nthaka

1. Umakaphatikizana ndi zidulo. Mu ichi kupanga mchere.
2. Wakwiya ndi alkalis kupanga tetra-, tri- ndi geksagidroksitsinkatov.
3. Nkhanizi anali kusungunuka mu amadzimadzi njira ammonia. Izi ndipamene Ammoniate zovuta.
4. Pamene alloying ndi oxides soda ndi mitundu okusayidi nthaka ndi zincate.
5. Pamene alloying ndi okusayidi pakachitsulo ndipo okusayidi boron, silicates nthaka, ndi mitundu makolala kunyezimira.

Monga okusayidi okonzeka nthaka (ZnO)

okusayidi nthaka akhoza zopezera mu njira zingapo:

• Natural mchere zincite;
• ndi moto nthaka nthunzi (Zn) mu mpweya (O) - otchedwa "French ndondomeko";
• ndi kuwonongeka matenthedwe wa mankhwala zotsatirazi: hydroxide Zn (o) 2, nthaka nthochi Zn (CH3COO) 2 nitrate Zn (NO3), carbonate ZnCO3;
• pansi zobwera chifukwa cha okosijeni ZnS yowotcha (nthaka sulfide);
• pamene Madziwo kaphatikizidwe;
• ndi m'zigawo za sludges ndi dusts smelters. Wa zinthu zofunika kwambiri ndi zomera kuti amakhazikika mu zitsulo zotha ntchito, munali chiwerengero chapadera cha chitsulo kanasonkhezereka.

okusayidi nthaka

okusayidi nthaka ntchito makampani labala, pepala, ena mapulasitiki, katundu mphira zikopa yokumba, zingwe magetsi, galasi, ziwiya zadothi, zodzoladzola (khungu creams, mankhwala kukongola) ndi zonunkhira. Izo ntchito monga activator kwa vulcanization zosiyanasiyana nkhani rubbers chothandizira kaphatikizidwe organic - methanol, chloroprene rubbers nthumwi vulcanizing, ndi pigment ndi filler mu kupanga. Poyamba okusayidi nthaka anafunika monga pigment woyera mu utoto ndi enamels, koma tsopano kwathunthu kuchotsedwa TiO2 (titaniyamu woipa ndi sanali poizoni). Ponseponse nthaka okusayidi ndipo ndinalowa mu utoto, tayala ndi mafuta kuyenga makampani.

Ponseponse ndi nthaka okusayidi mankhwala ndi mankhwala (mankhwala "nthaka mafuta", "Sudocrem", "Ikani Lassara"). Izo ntchito monga mbali ya mafuta wonunkhira bwino antiseptic, mu mawonekedwe a ufa. Zochita amagwiritsidwa ntchito kulenga bactericidal ndi chophimba denga mu zipatala, pamalo kudziletsa kuyeretsa. Ndi okusayidi nthaka opangidwa otsukira mano ndi kupanga kwa mano njira. Poyamba ntchito padziko lonse mafakitale kwa kuyeretsedwa photocatalytic madzi.

Komanso pansi kulingalira ndi mankhwala ntchito kupanga utoto ndi galasi zochokera galasi madzi, monga chimodzi cha dzimbiri remover ndi monga zowonjezera ku chakudya nyama. Komanso, ufa wa thunthu ndi nkhani zingamuthandize ngati sing'anga ntchito lasers ufa. Pamaziko a okusayidi nthaka analenga The LEDs mitundu buluu. Ena nanostructures (mwachitsanzo, woonda filimu) zochokera mankhwala angagwiritsidwe ntchito ngati masensa kwachilengedwenso kapena gasi tcheru.

Kodi ndi zovuta pa okusayidi nthaka anthu chiyani?

Izi pawiri mankhwala ali otsika kawopsedwe. Mu mpweya wa malo ntchito MPC sayenera miligram oposa 6 pa mita kiyubiki. Fumbi la okusayidi nthaka akhoza kupangidwa pa kuwomba mankhwala mkuwa. Ex ntchito ndi okusayidi nthaka ayenera mankhwala samalowa diso. Mankhwala ndi okusayidi nthaka tikulimbikitsidwa yekha monga mwa kulamula dokotala.
