Codsiga Alaabta

PM:
Codsiga dahaarka:PM, oo ah sun yar oo xoog leh, ayaa si weyn loogu isticmaalaa sidii dareere iyo wakiil isku xidha khad, dahaarka rinjiga iyo rinjiga ku salaysan biyaha. Waxay ku habboon tahay emulsion-ka benzene propylene, emulsion-ka propylene alkene acid iyo rinjigeeda emulsion-ka, kuwaas oo lagu garto yareynta heerkulka dahaarka, dedejinta isku xidhka iyo ilaalinta dahaarka xaalad wanaagsan.
Isticmaalka sunta cayayaanka:PM waxaa inta badan loo isticmaalaa dhexdhexaadinta metolachlor ee lagu dilo haramaha, iyo wakiilka joojinta ee emulsion-ka cayayaanka.
Codsiyada kale:PM waxaa loo isticmaali karaa ka hortagga qaboojiyaha shidaalka, nadiifiyaha, soo-saaraha, iyo wakiilka dhayidda macdanta ee biraha aan birta ahayn. Intaa waxaa dheer, waxaa loo isticmaali karaa sidii walxo isku-darka dabiiciga ah, midabaynta rinjiga iyo dharka, iyo dareeraha saliidda wareegaysa.

DPMwaxaa loo isticmaalaa dareere loogu talagalay xasiliyeyaasha PVC, nitrocellulose, ethyl cellulose, polyvinyl acetate, dareere loogu talagalay rinjiga iyo midabaynta, iyo qayb ka mid ah dareeraha biriiga. Waxaa loo isticmaali karaa dareere ahaan khad daabacan, rinji dhaldhalaal ah, dareeraha jarista iyo saliidda shaqaynaysa; sida wakiilka isku xidhka rinjiga ku salaysan biyaha (badanaa loo isticmaalo isku darka); sida dareeraha firfircoon ee rinjiga ku salaysan biyaha; sida dareeraha iyo wakiilka isku xidhka ee nadiifiyaha guriga iyo warshadaha, ka saarista dufanka iyo rinjiga, nadiifiyaha birta iyo dusha sare ee adag; sida dareeraha salka iyo wakiilka isku xidhka ee khad daabacaadda shaashadda xariirta ee nooca dareeraha ah; sida dareeraha iyo wakiilka isku xidhka ee dharka rinjiga weelka; sida wakiilka isku xidhka iyo wakiilka daryeelka maqaarka ee qaacidada qurxinta; sida xasiliyaha sunta cayayaanka iyo isku xidhka? wakiilka iftiimiyaha dabaqa.
