Naxaasta Aluminiumka ah ee aan Tolmada lahayn
1. Silig fidsan oo naxaas ah (aluminium) maro daboolan:
Cabbirka dhumucda -- A: 0.80 ~ 5.60mm;
Cabbirka dhumucda -- B: 2.00 ~ 16.00mm.
2. Maro daboolan oo naxaas ah (aluminium) silig wareegsan -- D: 1.90 ~ 5.00mm.
1. Xadhkaha aluminiumku waxa uu buuxiyey shuruudaha GB/T 55843-2009, iska caabinta 20℃ waa in ay ahaataa ≤0.02801 ω ·mm²/m;
2. Siligga naxaasta ah wuxuu u hoggaansamaa shuruudaha GB/T 55842-2009, iyo iska caabbinta 20 ℃ waa inay ka yaraataa ama la mid tahay 0.01724 ω ·mm²/m.
Cabbirka daareeyaha wareegsan waa inuu u hoggaansamaa shaxda soo socota:
| Dhexroor Magaca | leexasho |
| 0.90＜d＜taako=”＞≤2.50 | ±0.013 |
| 2.50＜d＜taako=”＞≤3.00 | ±0.025 |
| 3.00＜d＜taako=”＞≤5.00 | ±1%D |
Kordhinta dabaylaha wareega waa in ay raacdaa shaxda soo socota:
| Dhexroor Magaca | Min.Erabitaan % |
| 0.90＜d＜taako=”＞≤2.50 | 15 |
| 2.50＜d＜taako=”＞≤5.00 | 20 |
Waqtigan xaadirka ah, codsiga alaabada daahan silig elektromagnetic ah ayaa si weyn u kordhay isticmaalka fiilada korantada iyadoo la dardargelinayo xawaaraha dhismaha warshadaha casriga ah ee Shiinaha iyo koritaanka degdega ah ee alaabta dhoofinta.Siliga dahaarka leh iyo siliga elektromagnetic inta badan waxay isticmaalaan daahan budada ah ee korantada ah.Waqtigan xaadirka ah, waxaa inta badan loo isticmaalaa insulating oxide film silig electromagnetic halkii daawaynta sulfuric acid xooga leh ee silig aluminium, iyo sidoo kale waxaa loo isticmaali karaa in rinjiga dhaldhalaalka ah ee daahan rinjiga on-line.
Sababtoo ah dhumucda daahan ee daahan budada guud waxaa lagu dabaqi karaa silig wareeg ah oo leh dhexroor ka badan 1.6mm ama silig siman oo ballac ah in ka badan 1.6mm × 1.6mm, iyo daahan insulating leh dhumucdiisuna waxay ka badan tahay 40 μ m, laguma dabaqi karo dahaarka u baahan dahaarka khafiifka ah.Haddii daahan budada ah ee aadka u dhuuban la isticmaalo, dhumucda 20-40 μM waa la gaari karaa.Si kastaba ha ahaatee, sababtoo ah kharashka farsamaynta daahan iyo dhibka dahaarka, si ballaaran looma isticmaali karo.Marka dhumucda filimku aad u qaro weyn yahay, dabacsanaanta iyo hawlaha kale ee filimku waa la dhimay, taas oo aan ku habboonayn alaabta leh xagal foorarsi oo aad u weyn oo fiilada birta ah.Sababtoo ah xaddidaadda dhumucda filimka, silig dhuuban kuma habboona farsamada daahan budada ah.
