2. Marxaladda gaaska chromatography xal go'an, dareere, baraf-diid, balaastiiste iyo wakiilka fuuq-baxa
3.Dalka amaahda;humidizer;huurka;dawooyinka lidka ku ah;antioxidant;wakiilka hagaajinta unugyada;surfactant;xasiliye;dhumuc weyn leh;xakameynta cajiinka;emulsifier;wakiilka xawaash;wakiilka farsamaynta.GB2760 ~ 96 waxa ay ku taxan yihiin wax lagu daro cuntada.Waxaa inta badan loo isticmaalaa soo saarista xawaashka kala duwan, midabada, waxyaalaha lagu ilaaliyo, iyo checalbook vaniljka digirta, kernels qaxwaha dubay, iyo xawaashka dabiiciga ah.Waxyaalaha qoyaanka ah iyo kuwa jilicsan ee nacnaca, rootiga, baakadaha hilibka, jiiska, iwm. Waxa kale oo loo isticmaali karaa sidii caaryada kaaliyaha u adkaysta ee baastada iyo walxaha.Ku darista 0.006% soylk waxay ka dhigi kartaa dhadhanka isbeddelin inta lagu jiro kuleylka.Waxaa laga sameeyaa tofu baakad cad oo dhalaalaya, shiilkuna wuxuu kordhin doonaa mugga.
4. Doofaar-glycol waa dhexdhexaadka benzazole ee jeermiska.
5. Sida dareere ah, waxyaabaha lagu kaydiyo, midabada, antioxidants iyo kuwa kale ee cuntada lagu daro ee ay adag tahay inay ku milmaan biyaha sida biyaha ayaa lagu milmaa biyaha, ka dibna lagu daraa cuntada;waxay leedahay hygroscopicity xooggan waxayna leedahay saameyn qoyaan iyo dhaxan cuntada.Xeerarka dalkayga waxa loo isticmaali karaa macmacaan, iyadoo la isticmaalayo ugu badnaan 3.0g/kg.
6. Patyl glycol waa walxo muhiim ah oo loogu talagalay polyester-ka aan saturated lahayn, resin epoxy, iyo poliurethane.Qiyaasta aaggani waxay ka dhigan tahay 45% wadarta guud ee isticmaalka propylene glycol.Polyester-kan aan dheregsanayn wuxuu ku weyn yahay dahaarka dusha sare iyo caag la xoojiyay.Viscosity iyo hygroscopicity propylene glycol ayaa si fiican u sun ah.Sidaa darteed, waxaa si weyn loogu isticmaalaa warshadaha cuntada, daawada iyo qurxinta sida wakiilada qoynta, antifreeze, saliidaha iyo dareerayaasha.Warshadaha cuntada, propylene glycol iyo asiidhyada dufanku waxay ka falceliyaan si ay u abuuraan propylene glycol fatty acid.Buuga Kiimikada waxaa inta badan loo isticmaalaa sidii emulsifier cunto ahaan;propylene glycol waa dareere aad u fiican oo loogu talagalay xashiishyada iyo midabada.Pigbolly waxaa badanaa loo isticmaalaa sida dareere, jilciye, iyo wakiilka gumin samaynta noocyada kala duwan ee cadarka, boomaatada, iyo glycrastasus ee warshadaha dawooyinka.Sababtoo ah propylene glycol waxay leedahay milmayn wanaagsan oo leh noocyo kala duwan oo dhir udgoon ah, waxa kale oo loo isticmaalaa sida dareere iyo jilciye loogu talagalay qurxinta.Pigbolly waxa kale oo loo isticmaalaa sida dareere u ah maaddooyinka qoyaanka tubaakada, wakiilada caaryada iska ilaaliya, qalabka wax lagu farsameeyo ee saliidda lagu saleeyo iyo khad lagu calaamadiyo cuntada.Xalka hydraulic ee propylene glycol waa ka hortag waxtar leh.
7. Sida daawo qaadasho ahaan, wakiilka dawooyinka qayb ka mid ah.Waxaa loo isticmaali karaa sida qoyaanka ee alaabta la isku qurxiyo, jilciya, dareeraha, iwm. Warshadaha tubaakada waxaa loo isticmaali karaa sida qiiqa, moisturizers tubaakada, preservative, iwm Warshadaha cuntada waxaa loo isticmaalaa sida udgoon, dareerayaasha midabka la cuni karo, Kiimikada buugaagta cuntada baakadaha wakiilada jilicsan, Waxa kale oo loo isticmaali karaa in lagu soo saaro xabagta polyesterka ee aan saturated lahayn, iyo sidoo kale balaastikada, wakiilada fuuqbaxay, surfactants, wakiilada daaweeyayaasha, binders, iwm. Waxa kale oo loo isticmaali karaa warshadaha sida rinjiga, sunta cayayaanka, dahaarka iyo warshadaha kale
8. Ka saarista duulista, wakiilka barafaysan iyo qaboojiyaha, cuntada iyo xawaashyada, wakiilada udgoonka, waxyaalaha la isku qurxiyo iyo alaabta caafimaadka shakhsi ahaaneed, wareejinta kulaylka, dareeraha hadhka iyo biriiga, rinjiga iyo dahaarka, cuntada xayawaanka / quudinta xayawaanka, daroogooyinka, polyurethane, polyurethane, polyurethane, polyurethane , polyurethane, polyurethane, poliurethane, poliurethane, xabagta polyesterka aan saturated.
9. Walxaha, isku-dhafka organic, ka-hortagga barafka, caagagga, jeermiska.Heerarka falanqaynta chromatography gaaska.chromatography gaaska dareere go'an (heerkulka ugu badan ee 150 ° C, dareeruhu waa chloroform), falanqaynta go'doonsan khamriga, ester iyo ketone, iwm.
