Magnesium chloride

Colorless kristal nke, mgbe ihe ikuku gburugburu ebe obibi, ngwa ngwa-amalite tisaa - bụ magnesium chloride, onye usoro MgCI2. Ọ bụrụ na ha na-etisasịwo na mmiri, ihe ngwọta na-enweta na ọtụtụ-eji maka mmepụta nke dị iche iche na ụlọ ihe bụghị, e.g., Magnesia ciment. Nchekwa nke bekee ga-rụrụ na a kaa akara akpa, n'ihi na ọ bụ nnọọ hygroscopic.

N'ịbụ nke ọma mmiri-soluble umi, magnesium chloride ẹdude ke nkịtị mmiri nke oké osimiri, ma ọ na-hụrụ na ego nke potash, ebe ọ bụ na ụdị hexahydrate. Mere, nke a umi na-adịghị amịpụtara ọ bụla laabu na ulo oru usoro na-eji maka nnata nke eke ogige nke dị ọcha, na-enwetara kristal na-echi ọnụ n'ala. Dị ka a na-amalite ihe onwunwe, MgCl2 na-eji na njikere nke magnesium na magnesium oxide, n'ihi na mmepụta nke ire ọkụ retardant maka impregnating osisi. Ke adianade do, magnesium chloride eji maka nkwadebe nke a na-akpọ Sorel ciment. N'oge a mmepụta calcined magnesium oxide na-agbakwunyere a lekwasị ngwọta nke magnesium chloride.

The onwunwe nke a onwunwe - ngwa ngwa hardening na nkịtị ikuku okpomọkụ - na-enye ohere na ya iji dị ka ksilolita, akara na bonding ihe onwunwe na-ewu. Astringent Njirimara ekwe ojiji nke MgCl2 mgbe abịakọrọ sawdust na inweta fiberboard. Zvukoteploizoliruyuschy fiberboard eji dị ka a ihe onwunwe. hardening mmetụta a na-enweta n'ihi na hydrolysis usoro na inweta ya na Mg2OCl2 nnu nke bụ unyi anaghị agbasa na mmiri.

Umi bụ magnesium chloride n'ihi na ya elu hygroscopicity, bụ ike isonye na guzobere hydrates na mgbanwe ichekwa mmiri ụmụ irighiri. Larịị nke hygroscopicity wee buru ibu na ọ bụrụ na ihere iru mmiri bụ n'okpuru 50%, magnesium chloride, nakwa dị ka chlorides, calcium na lithium, anabata mbibi nke ọla. Otu onye dị otú hydrates - hexahydrate, nke bụ a agịga ekara kristal nke gbazee na 106 Celsius C. Na mmeghachi omume nke magnesium chloride na amonia kpụrụ ilu nnu uto rhomboid kristal nke bụ ngwa ngwa soluble na okenye agbanwe agbanwe na alcohols.

Onyinye magnesium chloride n'ihi ya Njirimara ukwuu forms isi salts nke nwere a na-echebe mmetụta. The ikwu nkwụsi ike nke ndị a salts na a okpomọkụ nso akpata ha dịgasị ojiji, ma ọ na-emepụta ezu nsogbu metụtara na gburugburu ebe obibi mmetọ. Karịsịa, potassium salts nke magnesium chloride eji na mbibi nke icing na okporo ụzọ na oyi. Mmetụta nke a ngwa bụ ejighị nnọọ n'aka, dị ka ọ bụ ihe ize ndụ wastewater mmetọ na mmebi n'ụdị corrosion.

Maka electrolytic mmepụta nke magnesium metal n'ụdị magnesium chloride a na-eji, nkwadebe nke a compound site dị otú ahụ na nkà na ụzụ nwere ike maka ọgwụ na nzube.

Ọdịdị nke umi, na mgbakwunye na nke ekwuola oké osimiri mmiri, pụtara n'ụdị carnallite. The bụ isi a ịnweta nọ Solikamsk district. Kacha nkịtị ebe magnesium chloride na-eji, ọ bụ engineering, ebe umi a na-eji rụọ ọrụ na usoro nke-agbaze snow. Na nri ụlọ ọrụ, a compound mara n'okpuru aha nke a nri mmako E511. Nke a mmako bụ dị ka a na nri akụrụngwa kacha-eji bi Japan. Ha na-akpọ ya "Nigar" - a ilu ihe ọṅụṅụ. Nigar nwetara ndammana site n'oké osimiri mmiri site evaporation. Ngwaahịa a nwere a dịgasị iche iche nke bara uru ọcha - ígwè, sodium, potassium, zinc na ndị ọzọ. Nigar na-eji tumadi dị ka a n'aka ịrahụ arahụ soy mmiri ara ehi na maka imewe nke Japanese mba nri nke tofu.
