Zinc waa bir bir-cad oo leh qaab-dhismeedka xaraashka ah ee xijaabka leh. Waxay leedahay dhibic dhalaal ah oo ah 419.58 ° C, oo ah qodob karkaraya oo ah 907 ° C, MOHS adkeyn ah oo ah 2.5, dib u hakinta korantada ee ah 0.02 ω ω · mm² / m, iyo cufnaanta 7.14 g / cm³.
Midabka zinc-ka ee 'zinc' waxay ku yimaadaan laba qaab dhismeedka walxaha ka kooban: laf-dhabarta iyo tuubada. Boodh-jeexjeexa zin-jecel wuxuu leeyahay awood dabool weyn.
Kimikoob ahaan, boodhka zinc waa mid aad u falcelin ah. Xaaladaha cimilada ee caadiga ah, waxay samaysataa lakab khafiif ah, cufan oo cufan oo hilib ah, kaasoo ka hortagaya fidsion dheeraad ah, taasoo ka dhigeysa mid u adkaysta jawiga ugu adkaysata jawiga. Si kastaba ha noqotee, uma adkaysato in lagu saleeyo cusbada aashitada ama aashitada. Waxay ku milmaysaa aashitada endingic, saldhigyada, iyo aashitada aashitada laakiin waa mid aan biyo ku dhex jirin.
Dhulka zinc wuxuu gubanayaa olol cad oo dhalaalaya oo ku jirta oksijiinta saafiga ah laakiin way adagtahay in la dhaco hawada caadiga ah, sidaa darteed looma kala saari karo inuu yahay mid guban kara. Deegaanka caadiga ah, boosteejooyinka zinc waxay ka falcelisaa qoyaan ama biyo si ay u soo saaraan gaaska hydrogen, laakiin heerka soosaarka hydrogen-ka waa mid aad u gaabis ah, in ka yar 1 l / kg · (kg · (kg ·). Sidaa darteed, boodhka zinc looma kala saari karo walax ay soo saarto gaasas guban kara marka aad la xiriirto biyaha. Si kastaba ha noqotee, kaydinta nabdoon iyo gaadiid, waxaa lagugula talinayaa in loola dhaqmo sidii fasal ahaan 4.3 shey khatarta ah (maaddooyinka qatar ah marka qoyan tahay). Waqtigan xaadirka ah, qawaaniinta ku saabsan kaydinta iyo gaadiidka ee budada zinc waxay ku kala duwan yihiin gobollada kala duwan ee Shiinaha, iyadoo qaar ka mid yihiin kuwa kale oo jilicsan iyo kuwa kale.
Booska zinc ayaa ku qarxin kara hawada, hanaan ku lug leh gubashada gaaska. Tusaale ahaan, boodh-ka-foosha foosha Micron-cabirku wuxuu leeyahay dib-u-dhac saaxiibtinimo oo aan fiicnayn oo ah 180 Ms, oo leh xaddidan qarax oo ah 1500-2000 g / m³. U fiirsashada 5000 g / m³, waxay gaartaa cadaadiska ugu badan ee qasaarada ah, cadaadiska qaraarka qasaarada ah ee kaco, iyo ugu badnaan MPA, 46.67 MPA / s, iyo 12.67 MPA · / Mpa, siday u kala horreeyaan. Qaramada Hazard heerka halista ah ee budada zins-cabirrada ah ee Micn-Sled waxaa loo kala saaraa ST1, oo muujinaya halista qasaarood oo aad u yar.
Qaababka wax soo saarka:
1. Sherstream-zaring screding:
Shiinaha ayaa leh zinc zinc badan oo zinc ah, oo ku dhawaad 20% kaydka adduunka, labaad oo keliya Australia. Shiinaha ayaa sidoo kale ah soosaaraha ugu weyn ee zinc ama ku tabarucaya saddex-meelood meel meel ka mid ah wax soo saarka adduunka, oo lagu qiimeeyo adduunka ugu horreeya ee adduunka. Nidaamka sceling-ka wuxuu ku lug leeyahay dib-u-habeynta zinc ore si uu u helo zinc sulfide, kaas oo markaa loo yareeyo zinc zinc-ka saafiga ah ee loo maro geedi socodka pyrometalling ama hydrometallicalgical, taasoo dhalisay zinc itooris.
Sanadkii 2022, waxsoosaarka zinc-ka Shiinaha ayaa soo saaray 6.72 milyan oo tan. Qiimaha noocyada zinc waxay ugu dambeyntii go'aamisaa qiimaha budada zinc-ka ee laf-dhabarta, oo lagu qiyaasi karo 1.15-1.2 jeer qiimaha zinc-ka zinc.
2. Habka 'zinc' ee 'zinc': **
(99.5%) zinc-ka waxaa lagu kululeeyaa ilaa 400-600 ° C si ka mid ah foornada ama foornada badaha ilaa la kariyey. Zinc-ka la dhalaaliyey ayaa markaa loo gudbiyaa si aan macquul ahayn oo loo yaqaan 'refractact cr cr cr cr cr and cr' iyo aqabbada xaaladaha kuleylka leh ee kululaynta iyo qanjirka, oo leh hawo isku buuqsan oo ah cadaadis 0.3-0.6 MPA. Budada zins ee zinc-ka ee zinc-ka ah waxaa lagu soo ururiyaa qashin-haye ka dibna waxaa ka gudbaya lakabyo badan oo gariir ah oo gariir u ah si loo kala saaro cabbir ka hor baakadaha kahor baakadaha.
3. Qaabka loo yaqaan 'zinc'.
Qaabkani wuxuu noqon karaa mid qalalan kara ama qoyan, soo saari kara boodhka weelka zicka ee qalalan ama u eg boodhka zake zinc. Tusaale ahaan, dhalada kubbadda qoyan waxay soo saari kartaa caraf udgoon zinc zinc zinc ah. Budada zinc ee atomized-ka ayaa lagu qasay xargaha dareeraha aliphactarbonow iyo qadar yar oo saliid ah oo ku dhex jira boorsada. Mar haddii hiwaayadda la doonayo iyo qaab-dhismeedka bullaacadda la doonayo, slurry-ka waxaa loo sifeeyaa si loo sameeyo chen che shatter oo ka badan 90% zinc zinc. Keega shaashadda ayaa markaa isku qasan si loo soo saaro slide-ka zinc ee jaakad, oo leh bir bir ah oo ka badan 90%.
Adeegsiga:
Booska zinc waxaa ugu horreyn lagu isticmaalaa warshadaha jaakadaha, sida ee ku jira jaakadaha anti-hodan ah ee zinc-anti-anti-securiton. Waxaa sidoo kale loo isticmaalaa midabyo, metallogy, kiimikooyin, iyo dawooyinka. Warshadaha jaakadaha ah ee ku dhawaad 60% ee dalabka zinc budada, waxaa ku xiga warshadaha kiimikada (28%) iyo warshadaha dawooyinka (4%).
Boorsada zirinc-ka ah waxay ka kooban tahay ku dhawaad walxaha laf-dhabarka, oo ay ku jiraan boodhka caadiga ah ee zinc-ka-wanaagsan ee loo yaqaan 'zinc'. Dambe wuxuu leeyahay nuxurka zinc-ka sareeya, wasakhda hoose, walxaha jilicsan, dhaqdhaqaaq dusha sare ah, oo loo qaybiyo cabirka qaniinyada, iyo kala-soocidda cabirkiisu yahay ciriiri, iyo kala-duwanaansho aad u wanaagsan, taasoo ka dhigaysa wax soo saarka waxqabadka sare. Ultra-wax-ka-nashaada-ka-wanaagsan ee 'zinc' zinc 'ayaa si weyn loogu isticmaalaa jaakadaha iyo codsiyada la-dagaallanka-ka-hortagga, gaar ahaan kuwa hodanka ah ee zinc-hodanka ah ama si toos ah loogu dabaqo jaakadaha anti---ka-soo-baxa. Xirmooyinka, boodhka zinc oo leh cabbir qayb ka yar wax ka yar 28 μm ayaa badanaa la isticmaalaa. Boos-sarre-High-High Pinc-ka-wanaagsan ayaa keydiya kheyraadka, waxay wanaajisaa hufnaanta adeegsiga, waxayna kor u qaadaa ka-hortagga qarashka ka hortagga xudunta, oo bixiya suuqa suuq weyn.
Booska zinc zinc waxay leedahay qaab-jilicsan oo loo yaqaan 'plake' oo ay soo saaraan kubad kubado ah ama uumiga uumiga jirka (PVD). Waxay leedahay saamiga xariifka sare (30-100), fiditaanka sare, daboolida, iyo gaashaafta guryaha, waxaana inta badan loo isticmaalaa jaakadaha da'romet (jaakadaha zinc-aluminium). Booska zinc zinc waxay bixisaa caymis wanaagsan, awooda sabeeya, awooda isku-darka, awoodda gaashaandhigga, iyo luster metlecic ah marka loo eego budada zersical zersical. Xoqanka 'Dacromet', boodh-karka zinc-ka ah ayaa ku faafaya si sahlan, sameynta lakabyo isbarbar socda oo wejiga wajiga, hagaajinta wajahda udhaxeysa zinc iyo sunta birta iyo ka dhex jira walxaha zinc. Tani waxay keenaysaa in la daato cufan, wado wado oo la dheereeyey, jidadka loo yaqaan 'zinc' iyo dhumuc daalaca ah, iyo gaashaandhiga gaashaandhiga iyo anti-anti-combosion. Xirmooyinka la-dagaallanka ee la-dagaallanka leh ee lagu sameeyay boodhka zinc ee zinc si fiican u difaac si aad u wanaagsan oo loo yaqaan 'milix' oo ka fiican caabbinta korantada ee korantada ka badan ama xargaha hufan, oo leh heerarka wasakheynta hoose, la kulma shuruudaha ilaalinta deegaanka.
