Zinc oxide. Izakhiwo kanye Izicelo

Zinc oxide (elinye igama - zinc oxide) - kuyinto i-nitrous amphoteric, crystalline kungekho nto enemibala emihle powder yellowing phezu Ukushisa akusheshi futhi ukushintsha ngezinye 1800 degrees. Zingaxazululeki emanzini. I namachibi zinc e zezakhi - 2. chemical ifomula ZnO. Lokhu kwaziswa kubaluleke kunazo zonke esintwini. It kunomphumela enezici emzimbeni womuntu.

Zinc oxide: izakhiwo Physical

1. I conductivity ezishisayo kuyinto 54 W / (m * K).
2. Kuyinto Semiconductor nge ububanzi iviyo 3.3 ev.

izakhiwo Chemical zinc oxide

1. It ihlangana acid. Kulesi yakha usawoti.
2. Ihlangana alkalis ukwakha tetra-, tri- futhi geksagidroksitsinkatov.
3. Lokhu kwaziswa kwaba ziyoncibilika e isixazululo ammonia aqueous. Lokhu yakha Ammoniate eziyinkimbinkimbi.
4. Lapho alloying nge oxides alikhali ne-zinc-nitrous amafomu a zincate.
5. Lapho alloying ne -silicon oxide ne boron oxide, zinc silicates, kanye namafomu ezinjengenyanga lwengilazi.

Njengoba uzilungiselele zinc oxide (ZnO)

Zinc oxide ingatholakala ngezindlela eziningana:

• Yemvelo amaminerali zincite;
• ovuthayo zinc umusi (Zn) e-oksijini (O) - lo okuthiwa "inqubo French";
• ngu noqhekeko ezishisayo zezakhi ezilandelayo: hydroxide Zn (OH) 2, i-zinc acetate Zn (CH3COO) 2 nitrate Zn (NO3), ZnCO3 carbonate;
• ngaphansi oxidative labadubuli ZNS (zinc sulfide);
• lapho zamagama ezingaphansi kolwandle;
• ngu isizinda sludges futhi dusts smelters. Okubaluleke kakhulu yilezo izitshalo ukuthi ngokukhethekile Scrap Metal, oqukethe ingxenye enkulu yensimbi lashukumisa.

Zinc oxide

Zinc oxide isetshenziswa irabha umkhakha, iphepha, abanye zepulasitiki, izimpahla iraba, lesikhumba yokufakelwa, izintambo zikagesi, ingilazi, izitsha zobumba, izimonyo (ukushuka okhilimu, beauty zokwelapha) namakha. Isetshenziselwa njengenhlangano Activator ukuze iqine ezahlukene rubbers kulethe zamagama udaba eziphilayo - methanol, chloroprene rubbers agent vulcanizing, isakhi sombala kanye yamathebhu ekukhiqizeni. Ngaphambili zinc oxide kwakudingeka njengoba sombala mhlophe upende enamels, kodwa manje exoshwa ngokuphelele TiO2 (ama-titanium dioxide akunakudluliswa enobuthi). Yande zinc oxide futhi ithole upende, isondo futhi uwoyela izimboni.

Yande ne-zinc-nitrous kwezokwelapha ekhemisi (izidakamizwa "Zinc Wamafutha", "Sudocrem", "Namathisela Lassara"). Isetshenziselwa njengengxenye wamafutha isinqandakuvunda, ngesimo izimpushana. Ngo umkhuba isetshenziswa ukudala amagciwane nophahla Uthwale ezibhedlela, self-yokuhlanza evele. Nge-zinc oxide ekhiqizwa toothpastes futhi ukuqinisa ngoba amazinyo izifo. Ngaphambili kusetshenziswa ngezinga ezimbonini ukuze ukuhlanzwa photocatalytic yamanzi.

Futhi ngaphansi ukucatshangelwa kuyinto into asetshenziswe ekukhiqizeni upende namabhodlela esekelwe ingilazi uketshezi, njengoba omunye ingxenye yesigaba sokubhekela izimo remover nokugqwala njengenhlangano okufakiwe ukuze kokudla kwezilwane. Ngaphezu kwalokho, lo powder efana sisetshenziselwa izinto ethembisa njengoba osebenzelana ukusebenzela powder lasers. Ngesisekelo zinc oxide wadala I LED imibala eluhlaza okwesibhakabhaka. Ezinye nanostructures (isib ifilimu elincanyana) esekelwe yalolu ketshezi ingasetshenziswa njengendlela izinzwa yemvelo noma igesi-sensitive.

Uyini umthelela womuntu zinc oxide?

Le ngxube yamakhemikhali has ubuthi ongaphakeme. Emoyeni kwezakhiwo zokusebenza MPC kufanele kube kungekho kuka 6 Miligram ngalinye imitha cubic. Uthuli zinc oxide zingase zimiswe phezu kokudubula imikhiqizo zethusi. umsebenzi Ex ne-zinc-nitrous kumele imfuyo Asingeni iso. Izidakamizwa ne-zinc-nitrous Kunconywa kuphela njengoba kwayala udokotela.
