Waa maxay faraqa u dhexeeya 3a, 4a iyo 5a seves molecular?Ma 3-daan nooc ee shaandhada molecular ayaa isku ujeedo loo isticmaalaa?Maxay yihiin arrimaha la xidhiidha mabda'a shaqada?Waa kuwee warshadaha ku habboon?Kaalay oo lasoco JXKELLEY.
1. Qaabka kiimikaad ee 3a 4a 5a shaandho molecular
3A qaacido kiimiko shaandho molecular: 2/3K₂O1₃·Na₂₂O·Al₂O₃·2SiO₂.·4.5H₂O
4A qaacido kiimiko shaandho molecular: Na₂O·Al₂O₃·2SiO··4.5H₂O
5A qaaciido kiimiko shaandho molecular: 3/4CaO1/4Na₂OAl₂O₃·2SiO··4.5H₂O
2. Baaxadda daloolka 3a 4a 5a shaandho molecular
Mabda'a shaqada ee shaandhada molecular inta badan waxay la xiriirtaa xajmiga daloolka shaandhada molecular, kuwaas oo ah 0.3nm/0.4nm/0.5nm siday u kala horreeyaan.Waxay ku dhejin karaan molecules gaaska dhexroorkoodu ka yar yahay cabbirka daloolka.Baaxadda cabbirka daloollada, way sii weynaataa awoodda xajinta.Baaxadda daloolku way kala duwan yihiin, waxyaalaha la shaandheeyay iyo kuwa la kala saarayna way kala duwan yihiin.Marka la eego siyaabaha fudud, 3a shaandho molecular kaliya waxay ku dhejin kartaa molecules ka hooseeya 0.3nm, 4a shaandho molecular, molecules adsorbed waa inay sidoo kale ka yaraadaan 0.4nm, iyo 5a shaandho molecular waa isku mid.Marka loo isticmaalo sida qallajiyaha, shaandhada molecular waxay nuugi kartaa ilaa 22% miisaankeeda qoyaanka.
3. 3a 4a 5a warshadaha codsiga shaandhada molecular
3 Shaleemo molecular inta badan waxaa loo isticmaalaa in lagu qalajiyo gaaska dildilaaca batroolka, olefin, gaaska sifaynta iyo gaaska saliidda, iyo sidoo kale qallajiye kiimikaad, dawooyinka, galaaska dahaadhka ah iyo warshadaha kale.Inta badan waxaa loo isticmaalaa qalajinta dareeraha (sida ethanol), qalajinta hawada ee galaaska dahaadhka, nitrogen iyo hydrogen qalajinta gaaska isku qasan, qalajinta qaboojiyaha, iwm.
4 Shaandhooyin molecular ah ayaa inta badan loo isticmaalaa in lagu qalajiyo gaaska dabiiciga ah iyo gaaska kiimikada kala duwan iyo dareerayaasha, qaboojiyaha, daawooyinka, xogta elektaroonigga ah iyo walxaha kacsan, nadiifinta argon, iyo kala soocida methane, ethane iyo propane.Inta badan loo isticmaalo qalajinta qoto dheer ee gaaska iyo dareeraha sida hawada, gaaska dabiiciga ah, hydrocarbons, qaboojiyaha;diyaarinta iyo nadiifinta argon;qalajinta joogtada ah ee qaybaha elektaroonigga ah iyo walxaha burburay;Walaxda fuuqbaxa ee rinjiyada, polyester-ka, midabada iyo dahaarka.
5Shandho molecular waxaa inta badan loo isticmaalaa qalajinta gaaska dabiiciga ah, ka saarista kaarboon laba ogsaydh;kala-soocidda nitrogen iyo oksijiinta si loo diyaariyo oksijiinta, nitrogen iyo hydrogen;dewaxing batroolka si loo kala saaro hydrocarbons caadiga ah iyo hydrocarbons laami ah iyo hydrocarbons wareeg ah.
Si kastaba ha ahaatee, aagga weyn ee gaarka ah ee dusha sare iyo xayeysiinta dabaysha ee shaandhada molecular ee la cusboonaysiin karo waxay gaari kartaa xayaysiin qoto dheer oo biyo ah iyo ammonia hadhaaga ah.Isku-darka nitrogen-hydrogen-ka ee burburay wuxuu galaa qalajiyaha si uu uga saaro qoyaanka haraaga ah iyo wasakhda kale.Qalabka sifaynta wuxuu qaataa munaaradaha xayeysiiska labanlaaban, mid wuxuu nuugaa gaaska qallafsan ee ammonia, kan kalena wuxuu qurxiyaa qoyaanka iyo ammonia haraaga ah ee kuleyl (guud ahaan 300-350 ℃) si loo gaaro ujeedada dib u soo kabashada.Hadda, miyaad heli kartaa faraqa u dhexeeya 3a 4a 5a shaandho molecular?
