Codsiga Alaabta

PnB waxaa inta badan loo isticmaalaa sida wakiilka nadiifinta wasakhda culus. Waxay si hufan u milmi kartaa isku-xidhka saliidda iyo dufanka waxayna ka dhigi kartaa mid ku habboon qaabka qoyska iyo warshadaha. Qayb ahaan biyaha ku milmay, PnB waxay ku milmi kartaa dareeraha ugu badan codsiga sida soo socota:

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

② sida wakiilka isku dhafka ah ee waxtarka leh iyo dareeraha daaha-yaraynta biyaha;

③ sida wakiilka xinjirowga ee waxtarka leh ee rinjiga emulsion-ka ee biyaha;

④ sida dareeraha firfircoon ee rinjiga ku salaysan dareeraha;

⑤ sida dhexdhexaadinta kiimikaad ee ester, dareeraha iyo soo saarista balaastiga.

DPnB
Codsiga dahaarka:Sida mid ka mid ah kaaliyeyaasha ugu fiican ee samaynta filimada ee rinjiga biyaha ku salaysan, DPnB waxaa loo isticmaali karaa sidii xinjiraha resin acrylic, phenylethylene acrylic resin iyo polyvinyl acetate oo siinaya waxqabad aad u fiican si loo rinjiyeeyo filimka.
Codsiga ku jira nadiifiyaha: waxay khusaysaa walxaha nadiifinta gaar ahaan kuwa u baahan xawli yar oo deg deg ah, sida wax ka saara iyo nadiifiyaha sagxadda. Sida wakiilka wanaagsan ee isku xidhka ee saliidaynta dufanka iyo dufanka, DPnB waxa loo marsan karaa sida rinji-qaade iyo ka saara dufanka xoolaha.
Codsi kale:DPnB waxa kale oo loo isticmaali karaa wax soo saarka beeraha, waxyaalaha la isku qurxiyo, qalin elektarooniga ah iyo dunta.
