Codsiga Alaabta:
1.Waxa inta badan loo isticmaalaa sida dareeraha saliidda, nitrocellulose, resin synthetic, dheeha khamriga iyo ethyl cellulose;loo isticmaalo sida wakiilka qalajinta degdega ah ee varnish iyo daahan daahan ee warshadaha daahan;loo isticmaalo sida wakiilka wax gasha iyo wakiilka siman ee daabacaadda iyo warshadaha midabaynta;loo isticmaalo wax lagu daro warshadaha shidaalka;loo isticmaalo sidii kaaliye dheehaynta warshadaha dunta;loo isticmaalo sida dhexdhexaadka ah ee synthesis organic.Diethylene glycol monomethyl ether waxaa inta badan loo isticmaalaa sida dareere aad u karsan oo loogu talagalay khad, dheeh, resin, cellulose iyo rinjiga, waxaana lagu dari karaa rinjiga si ay u sahlanaato qulqulka, buraash iyo heerkulbeegga, waxaana loo isticmaali karaa soosaaraha hydrocarbon. , Dhexdhexaad u ah diyaarinta derivatives ester ee warshadaha synthesis organic iyo reagent kiimikaad ee kimistari gorfaynta.Polyethylene glycol monomethyl ether ayaa loo isticmaali karaa sidii dareeraha biriiga.
2.Waxa loo isticmaali karaa sida dareere ah dheeha milmaya, khad daabacaadda, cortisone, iwm. ee khamriga iyo kala firdhiso sunta cayayaanka, wakiilka daawaynta maqaar iyo balaastikada.
3.Widely loo isticmaalo sida dareeraha iyo dareeraha rinjiga nitrofibre, varnish, dhaldhalaalka, iwm.;dareere aan firfircoonayn ee xabagta;dareere ah dhammaan noocyada saliidda iyo dufanka, lignin, nitrocellulose, acetate cellulose, dheeha alkolada-milmi leh, daabacaadda khad iyo xabagta synthetic iyo sidoo kale kala firdhiso cayayaanka, wakiilka daaweynta maqaarka, balaastiigiyaha, dhalaalaya, iyo dhexdhexaad ah ee synthesis organic.
4.Loo isticmaalo sida dareere.
Qoraalada Kaydinta Alaabta:
1. Ku kaydi bakhaar qabow oo hawo leh.Ka fogow dabka iyo isha kulaylka.Shuruudaha baakadaha waa la xidhay, oo aan la xidhiidhin hawada.
2.Waa in si gooni ah loo kaydiyaa walxaha oksida, acids, iwm, waana in aan la isku darin.Waa inaan lagu kaydin tiro badan ama wakhti dheer.
3.Ku qalabaysan noocyo ku habboon iyo tirada qalabka dab-damiska.Aagga kaydinta waa in lagu qalabeeyaa qalabka daaweynta degdegga ah ee daadsan iyo agab hoy oo ku habboon.
