Toddobaadkan, xarunta qiimaha alaabada ee silsiladda warshadaha ee phenol-ketone guud ahaan way hoos u dhacday. Kharash yar oo soo mara, oo ay weheliso cadaadiska saadka iyo baahida, ayaa cadaadis gaar ah oo hoos u dhac ah ku keenay qiimaha silsiladda warshadaha. Si kastaba ha ahaatee, alaabada kor u socota waxay muujiyeen iska caabin hoose oo weyn marka loo eego kuwa hoose, taasoo keentay hoos u dhac ku yimid faa'iidada warshadaha hoose. Inkasta oo faa'iidada warshadaha phenol-ketone ee dhexe ay yaraadeen, faa'iidada guud ee alaabada kor u socota iyo kuwa dhexe ayaa weli daciif ahayd, halka warshadaha hoose ee MMA (Methyl Methacrylate) iyo isopropanol ay wali sii wadaan faa'iido gaar ah.
Marka la eego qiimaha celceliska toddobaadlaha ah, marka laga reebo koror yar oo ku yimid qiimaha celceliska toddobaadlaha ah ee phenol (oo ah badeecad dhexdhexaad ah), dhammaan alaabada kale ee silsiladda warshadaha phenol-ketone ayaa hoos u dhacay, iyadoo intooda badan ay hoos ugu dhaceen inta u dhaxaysa 0.05% ilaa 2.41%. Kuwaas dhexdooda, alaabta kor ka soo baxda ee benzene iyo propylene labaduba way daciifeen, iyadoo qiimaha celcelis ahaan toddobaadlaha ah uu hoos ugu dhacay 0.93% iyo 0.95% bishiiba siday u kala horreeyaan. Inta lagu jiro toddobaadka, ka dib koror yar oo isdaba joog ah, qiimaha mustaqbalka saliidda cayriin wuxuu arkay hoos u dhac muddo gaaban ah oo sii kordhaya. Xaaladaha suuqa dhammaadka ayaa ahaa kuwo gaabis ah, dareenka taxaddarka hoosena wuu xoogganaa. Si kastaba ha ahaatee, baahida isku darka shidaalka ee Mareykanka ayaa kor u qaaday qiimaha toluene, cutubyada isku dheelitir la'aantana waa la xiray sababo la xiriira faa'iidooyin dhaqaale oo liita, taasoo keentay dib u soo kabasho qiimaha benzene dhammaadka toddobaadka. Dhanka kale, qaar ka mid ah cutubyada propylene ee hoos u dhaca ayaa dib u bilaabay hawlgalladooda, taasoo si yar u xoojisay taageerada baahida ee propylene. Guud ahaan, inkastoo dhammaadka walxaha ceeriin ay muujiyeen isbeddel daciif ah, hoos u dhacu wuxuu ka yaraa kan alaabada hoose.
Badeecadaha dhexdhexaadka ah ee phenol iyo acetone ayaa inta badan dhinac ka ganacsan jiray, iyadoo isbeddello cidhiidhi ah ay ku yimaadeen celceliska qiimaha toddobaadlaha ah. Iyadoo ay jirto hoos u dhac ku yimid qiimaha, qaar ka mid ah cutubyada bisphenol A ee hoos u dhaca ayaa dib u bilaabay hawlgalladooda, waxaana jiray rajooyin laga qabay dayactir cutubyada phenol-ketone ee Hengli Petrochemical muddada dambe. Qodobbada dheer iyo kuwa gaaban ayaa isku xidhmay suuqa, taasoo keentay ismari waa u dhexeeya iibsadayaasha iyo iibiyayaasha. Badeecadaha hoose waxay arkeen isbeddel hoos u dhac ah oo ka muuqda dhammaadka kharashka sababtoo ah sahay ku filan iyo la'aanta horumar ku yimid baahida dhammaadka. Toddobaadkan, celceliska qiimaha toddobaadlaha ah ee warshadaha hoose ee MMA ayaa hoos u dhacay 2.41% bil-bil, taasoo ah hoos u dhacii ugu weynaa ee toddobaadlaha ah ee silsiladda warshadaha. Tani waxay inta badan sabab u ahayd baahida dhammaadka oo daciif ah, taasoo keentay sahay ku filan oo suuqa ah. Gaar ahaan, warshadaha ku salaysan Shandong waxay la kulmeen cadaadis weyn oo kaydka ah waxayna ahayd inay hoos u dhigaan qiimaha si ay u kiciyaan shixnadaha. Warshadaha hoose ee bisphenol A iyo isopropanol ayaa sidoo kale la kulmay isbeddello hoos u dhac ah oo gaar ah, iyadoo celceliska qiimaha toddobaadlaha ah uu hoos u dhacay 2.03% iyo 1.06% siday u kala horreeyaan, maadaama suuqu uu ku sii jiray wareeg daciif ah oo hagaajin heer hoose ah iyadoo ay jirto cadaadis sahay iyo baahi.
Marka laga hadlayo faa'iidada warshadaha, inta lagu jiro usbuuca, oo ay saameeyeen saameynta hoos u dhaca ee cadaadiska saadka iyo baahida ee sii kordhaya ee warshadaha hoose iyo kharashka oo daciif ah, faa'iidada alaabada hoose ee silsiladda warshadaha ayaa muujisay isbeddel hoos u dhac ah. Inkasta oo faa'iidada guud ee warshadaha phenol-ketone ee dhexdhexaadka ah ay soo hagaagtay, haddana faa'iidada guud ee aragtiyeed ee silsiladda warshadaha ayaa si weyn hoos ugu dhacday, inta badan alaabada silsiladda ku jirtana waxay ku jireen xaalad khasaare ah, taasoo muujinaysa faa'iidada silsiladda warshadaha oo daciif ah. Kuwaas waxaa ka mid ah, warshadaha phenol-ketone waxay diiwaan geliyeen kororka ugu weyn ee faa'iidada: khasaaraha aragtiyeed ee warshadaha toddobaadkan wuxuu ahaa 357 yuan/ton, taasoo soo gaabisay 79 yuan/ton marka la barbar dhigo usbuucii hore. Intaa waxaa dheer, faa'iidada warshadaha hoose ee MMA ayaa si weyn hoos ugu dhacday, iyadoo celceliska faa'iidada guud ee aragtiyeed ee toddobaadlaha ah ee warshadaha uu ahaa 92 yuan/ton, taasoo ah hoos u dhac 333 yuan/ton laga soo bilaabo usbuucii hore. Guud ahaan, faa'iidada hadda jirta ee silsiladda warshadaha ee phenol-ketone waa mid daciif ah, iyadoo inta badan alaabada ay wali ku xayiran yihiin khasaarooyin. Warshadaha MMA iyo isopropanol oo keliya ayaa leh faa'iido aragtiyeed oo wax yar ka sarreysa xariiqda jebinta-siman.
Diiradda Muhiimka ah: 1. Muddada gaaban, qiimaha mustaqbalka ee saliidda cayriin waxay u badan tahay inay sii ahaato isbeddel isbeddelaya oo daciif ah, kharashyada daciifka ahna waxaa la filayaa inay sii socdaan. 2. Cadaadiska saadka ee silsiladda warshadaha ayaa weli jira, laakiin qiimaha alaabada silsiladda warshadaha ayaa maraya heer hoose oo sannado badan ah, sidaa darteed qiimaha hoos u dhaca ayaa laga yaabaa inuu xaddidan yahay. 3. Way adag tahay in warshadaha isticmaalaha ugu dambeeya ay arkaan horumar la taaban karo, baahida daciifka ahna waxay sii wadi kartaa inay bixiso jawaab celin taban oo kor u kaca.
