Ka taxadarida gaadiidka: Alaabtani waa dareere, si adag ayaa loo mamnuucay in lagu qaso oksidat, kiimikooyinka la cuni karo, alkali, anhydride acid, iwm. Inta lagu jiro gaadiidka, waa in laga ilaaliyaa soo-gaadhista qorraxda, roobka iyo heerkulka sare.Xagaaga ilaa inta suurtogalka ah ee gaadiidka subaxda iyo fiidkii, si looga hortago soo-gaadhista iftiinka qoraxda, gaadiidka sida waafaqsan khadka la cayimay, joogsiga waa inuu ka fogaadaa dabka, ilaha kulaylka, aagga heerkulka sare.Waxaa si adag loo mamnuucay in alaabta lagu qaado isla gaadhiga kiimikooyinka la cuni karo.Markaad waddo ku raacayso, waa inay raacdaa waddadii loo qoondeeyay oo yuusan joogin meelaha la deggan yahay iyo meelaha dadku ku badan yahay.Waa mamnuuc in lagu dhex simbiro gaadiidka tareenada.Maraakiibta alwaaxda ah iyo maraakiibta sibidhka ayaa si adag looga mamnuucay gaadiidka badan.
P-tert-butylphenol waxay leedahay sifooyin antioxidant waxaana loo isticmaali karaa xasiliye ahaan caagga, saabuunta, hydrocarbons koloriin leh iyo fiilooyinka dheefshiidka.Uv nuugista, sunta cayayaanka, caagga, rinjiga iyo walxaha kale ee ka hortagga dildilaaca.Tusaale ahaan, loo isticmaalo xabagta polycarbon, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, styrene stabilizer.Intaa waxaa dheer, sidoo kale waa alaabta ceeriin ee cayayaanka daawada, sunta cayayaanka iyo acaricide, udgoonka iyo wakiilka ilaalinta dhirta.Waxa kale oo loo isticmaali karaa jilciye, dareere, lagu daro dheeha iyo rinjiyada, antioksidanter ee saliidda saliidda, demulsifier saliid iyo daro ee shidaalka baabuurta.
Codsiyada kale:
(1) Saliidda phenolic ee ku milma saliidda, badeecada iyo uumiga formaldehyde waxaa loo heli karaa ujeedooyin kala duwan.In xabagta chloroprene isku qasan 10-15% ee alaabta, si aad u hesho xabagta milmi, noocan oo kale ah koollada waxaa inta badan loo isticmaalaa in gaadiidka, dhismaha, madaniga ah, kabo-samaynta, iwm In khad daabacaadda, waxaa loo isticmaali karaa beddelka rosin, dhimis. daabacaad, sawir-qaadis heersare ah iyo wixii la mid ah.Daboolka dahaarka ah, waxaa loo isticmaali karaa varnish dip gariiradda iyo laminate varnish.
(2) Soo saarista polycarbonate, sida fosgene polycarbonate wakiilka joojinta falcelinta, ku darida qaddarka buug-Kimikada 1-3% ee xabagta.
(3) Loo isticmaalo resin epoxy, wax ka beddelka resin xylene;Sida polyvinyl chloride stabilizer, surfactant, nuugeeyaha UV.
(4) Iyada oo leh sifooyinka antioxidant, waxaa loo isticmaali karaa sidii caag, saabuun, hydrocarbons koloriin leh iyo nitrocelluloose stabilizer.Sidoo kale waa walxo cayriin ah oo ka hortag ah cayayaanka (daaw), acaricide acaride (cayayaanka cayayaanka) iyo wakiilka ilaalinta dhirta, udgoonka, resin synthetic, iyo sidoo kale waxaa loo isticmaali karaa jilciye, dareere, dheeh iyo rinji lagu daro.Waxa kale oo loo isticmaali karaa sida walxaha demulsifier ee goobta saliidda iyo wax lagu daro saliidda baabuurta.
