Codsiga Alaabta

PnBWaxaa inta badan loo isticmaalaa sidii wakiil nadiifin ah oo loogu talagalay wasakhda culus. Waxay si hufan u milmi kartaa saliidda isku xidhka iyo dufanka waxayna ka dhigi kartaa mid ku habboon qaacidada guriga iyo warshadaha. Qayb ahaan ku milmi karta biyaha, PnB waxay milmi kartaa dareeraha ugu badan iyadoo la adeegsanayo sidan soo socota:

① sida nadiifiyaha guriga iyo warshadaha, ka saara dufanka iyo rinjiga, wakiilka isku xidhka iyo dareeraha nadiifinta birta iyo dusha sare ee adag;

② oo ah wakiil isku xidha oo wax ku ool ah iyo dareere ah dahaarka biyaha yareeya;

③ sida wakiilka isku-xidhka waxtarka leh ee rinjiga emulsion-ka ku salaysan biyaha;

④ sida dareeraha firfircoon ee rinjiga ku salaysan dareeraha;

⑤ sida kiimikada dhexdhexaadka ah ee wax soo saarka ester, dareeraha iyo balaastikada.

DPnB
Codsiga dahaarka:Iyada oo ah mid ka mid ah kaaliyaha ugu fiican ee sameynta filimada rinjiga ku salaysan biyaha, DPnB waxaa loo isticmaali karaa sidii isku-darka resin acrylic, resin acrylic phenyethylene iyo polyvinyl acetate taasoo siinaysa waxqabad aad u fiican filimka rinjiga.
Codsiga nadiifiyaha:Waxay khuseysaa walxaha nadiifinta gaar ahaan kuwa u baahan xawaare hooseeya oo isbeddelaya, sida ka saarista shamaca iyo nadiifiyaha dabaqa. Maadaama ay tahay wakiil isku xidh wanaagsan oo loogu talagalay saliidaynta dufanka iyo dufanka, DPnB waxaa loo isticmaali karaa sidii ka jarista rinjiga iyo ka saarista dufanka xayawaanka.
Codsiga kale:DPnB waxaa sidoo kale loo isticmaali karaa wax soo saarka beeraha, qurxinta, khad elektaroonig ah iyo dharka.
