Waa maxay macdanta ah? Views iyo fikradaha

Wixii qarniyo, ra'yigaaga ku saabsan waxa macdanta ayaa si joogto ah la beddelo. Haddaba, haddii aynu u jeceshahay ama ma, on dhinacyada oo dhan, inaannu tagno oo ku saabsan macdan ah. Haddii aad aaminsan this "Love" in advertising oo dhan, waxay meel kasta waa, laga bilaabo daawada cadayga iyo cunto afjaridda bisadaha jeermis dilay.

Sidaas waxa macdan? Oo hadda ku saabsan fikradda this ma jiro iswaafiqitaan iyo doodda sii. Haddii aad fududeeyo qeexidda jira, jawaabta su'aasha "Waa maxay macdanta ah" lagu soo koobi karaa sida soo socota: Macdanta jira cunnooyinka adkaha ah isagoo asal ahaan dabiiciga ah iyo qaab-dhismeedka crystal ka imanba, ka kooban oo ka mid ah oo matali kara by formula kiimikada. Taasi waa, sida ay qeexitaankan, macdan - yihiin walxaha sameeyay in koorsada ah hababka dhulka iyo Halabuurka kiimikada lagu qeexay. Waxay dareemi kartaa jidh ahaan, in uu yahay, dareemay, qiyaasay, miisaamay, ama wax tusa, xataa haddii iyadoo la kaashanayo qalabka indhaha. Marka laga eego this, fariinta ku saabsan macdan ah, tusaale ahaan, cuntada cat, sida aan ka maqal commercials, waxa ay u muuqataa ugu yaraan in xayaysiin ah sumcad caadiga ah, laakiin by waaweyn iyo - macno darro dibadda. Iyadoo ay run tahay waxaa jira macdanta dabiiciga ah, taas oo aan la kulmaan maalin walba guriga, waxa ka badan, iyada oo aan taas oo ay adag tahay in la damacsan nolol buuxda. Mid ka mid ah iyaga ka mid ah - ee cusbo leh dhagaxayga weyn (halite).

A sifo aad u muhiim ah oo ah macdanta ee qeexitaankan waa "asal ahaan ka imanba dabiiciga ah." Oo xiiso gaar ah waa "dabiiciga ah" asal ahaan. Waxaa jira tiro badan oo kiimiko ah imanba kala duwan lagu yaqaan in ay farmashiye, laakiin kaliya jajab yar oo ka mid ah xeryahooda helay ee dabiiciga ah, sida wakiil ka ah macdanta qeexidda baahisey. Sababtuna waxay tahay, in farmashiye ee shaybaarka fursad u leeyihiin inay abuuraan jawi kala duwan ka badan ka jira in dabeecadda dhabta ah, iyo ururiyaan in a "shirkad" waa kiimikada in si dabiici ah u wada dhacaan shiidaa.

Sii si aad u ogaato, si kastaba ha ahaatee, in macdanta sida, oo wixii aan, waxaan la soco in, si adag u hadlayay, dheeman dardaro iyo luul, abuuray in shaybaar, loo yaqaan macdanta ma. Ma loo saarin karaa in ay macdan ka mid yihiin dabiiciga ah iyo (in kasta oo ay asal ahaan dabiiciga ah), oo caan ah tan iyo Qarniyadii hore iyo cadaatay jet isagoo nooc viscous of dhuxusha. Sababta - la'aan qaab-dhismeedka crystal.

Qaar badan oo farmashiye su'aalo kala saaro macdanta bixisey iyo Meerkuridu - biraha kaliya in dhacdaa si dabiici ah qaab dareere ah. Horaantii, marka doorka ugu weyn waxaa la ciyaaray ay Halabuurka, mercury waxaa loo tixgeliyaa inay macdanta ah (si kastaba ha ahaatee, biyaha ayaa sidoo kale) ee kala soocidda ee macdanta. Haddaba, marka qeexidda macdanta waxaa lagu daray iyo joogitaanka dhismeedka crystal ah, inta badan ee farmashiye walxaha dareere dabiiciga ah fasalka ee macdanta lama filayo.

In taxanaha ah ee aan loo isticmaalaa in lagu maqlo Xusuuso luul dahabka qaali ah. Si kastaba ha ahaatee, ma la odhan karaa macdanta ah ay sabab u tahay xaqiiqda ah in ay qaab-dhismeedka waa inhomogeneous. In ay ka kooban yahay macdanta joogo calcite (carbonate calcium, wax crystalline) iyo walxaha organic, mid kasta oo ka mid ah qaybaha dastuurka uu leeyahay Halabuurka kiimikada ah.

Currently, ereyga "macdanta" oo waxaa badanaa loo isticmaalaa sida magaca taxane macdanta ah, iyo sida magaca hal crystal ah. Tusaale ahaan, diamond waa hanti gaar ah sida ay darantahay ingeega, fahamsan yahay hantida guud ee kiristaalo of noocyada macdanta. Laakiin marka aan ka hadlayno mid ka mid ah diamond ee dunida ugu weyn "Cullinan", macnaha qaaday si gooni gooni ah macdanta.
