Qaraxa Shenhai-Caddaynta
Iyada oo ku saleysan Tusmada Dabagalka Isbarbardhigga (CTI), Qalabka dahaarka adag ee loo isticmaalo qalabka korantada ee badbaadada leh waxaa loo kala saari karaa saddex heer: I, II, iyo IIa, sida ku cad shaxda 1.9. Sida laga soo xigtay GB/T 4207-2012 “Hababka lagu Go'aamiyo Tusmooyinka Dabagalka Korontada ee Walxaha Dahaarka Adag,” Qiimaynta alaabta dahaarka ee sida caadiga ah loo isticmaalo ayaa la bixiyaa, sida lagu faahfaahiyay Shaxda 1.10.
| Heerka maadada | Marka la barbar dhigo Tusmada Raadinta (CTI) |
|---|---|
| I | 600≤CTI |
| II | 400≤CTI#600 |
| IIIa | 175≤＜400 |
Marka laga reebo kala soocidda walxahan, Alaabta dahaadhku waa inay sidoo kale buuxiyaan shuruudaha heerkulka shaqada. Haddii qalabka korantada ee la xoojiyay uu ku shaqeeyo xaalado aan caadi ahayn oo la ogol yahay oo lagu qiimeeyay xaaladdiisa shaqo, shaqadeeda ugu badan heerkulka waa in aysan si xun u saameyn qalabkeeda makaanikada iyo korantada. Sidaa darteed, heerkulka xasiloon ee walxaha dahaarka waa in uu ahaado ugu yaraan 20 ° C ka sarreeya heerkulka ugu sarreeya ee qalabka, oo aan ka hooseynin 80 ° C.
| Heerka maadada | Qalabka dahaarka |
|---|---|
| I | dhoobada dhalaalaysa, miica, muraayad |
| II | Melamine asbestos arc caag u adkaysta, silikoon organic dhagax arc caag u adkaysta, Walxaha kooxda polyester-ka aan saturated |
| IIIA | Polytetrafluoroethylene caag ah, melamine galaas fiber fiber caag ah, looxa maro galaas epoxy oo dusha lagu daweeyay rinji u adkaysta arc |
Naqshadayaashu waxay dooran karaan qalabka dahaadhka ee ku habboon iyadoo lagu saleynayo tamarta shaqada ee qalabka korantada iyo shuruudaha kale ee la xiriira. Haddii alaabta aan kor ku soo sheegnay aysan buuxin baahiyaha naqshadeynta, agabka kale waa la tijaabin karaa oo lagu qiimeyn karaa sida ku cad habka imtixaanka caadiga ah (GB/T 4207-2012).
Waa muhiim in taas la ogaado “alaabta dahaarka adag” tixraac walxaha adag inta lagu jiro hawlgalka. Agabka qaar, kuwaas oo dareere ah wakhtiga sahayda oo adkeeya codsiga, waxaa sidoo kale loo tixgeliyaa alaab adag oo dahaarka, sida varnishes dahaarka ah.
