1,Tallaabooyinka muhiimka ah ee xulashada
1. Go'aami habka kululaynta
Kuleylinta wajiga dareeraha: Ku habboon nidaamyada xiran ee heerkulka ≤ 300 ℃, fiiro gaar ah waa in la bixiyaa saameynta viscosity ee dareeraha.
Kululaynta wajiga gaaska: ku habboon nidaamyada xiran ee 280-385 ℃, oo leh hufnaan kuleyl sare leh laakiin u baahan xasilloonida kuleylka sare.
2. Deji xadka heerkulka
Heerkulka ugu badan ee hawlgalka: Waa inuu ahaadaa 10-20 ℃ ka hooseeya qiimaha magaca ah ee saliidda wareejinta kulaylka (sida 320 ℃ qiimaha magacaaban, isticmaalka dhabta ah ≤ 300 ℃) si looga fogaado coking ama oksaydhka.
-Heerkulka ugu yar ee hawlgalka: Viscosity waa in la hubiyaa inuu yahay ≤ 10mm ²/s (haddii baafinta kulaylka loo baahan yahay xilliga jiilaalka si looga hortago adkaanta).
3. Nooca nidaamka iswaafajinta
-Nidaamka xiran: Badbaadada sare, ku haboon hawlgalka joogtada ah, lagu taliyey saliid wareejinta kulaylka synthetic (sida isku dhafka diphenyl ether).
-Nidaamka furan: Waa lagama maarmaan in la doorto saliidda macdanta leh sifooyinka antioxidant xooggan (sida L-QB300) oo la gaabiyo wareegga beddelka.
2,Doorashada nooca saliidda kulaylka
Nooca macdanta ayaa leh qiimo jaban iyo celceliska kuleylka, kuna xaddidan isticmaalka wajiga dareeraha ≤ 300 ℃ LQB300 LQC320
Nooca synthetic wuxuu leeyahay xasillooni kulayl xoog leh (ilaa 400 ℃) wuxuuna ku habboon yahay wajiga gaaska iyo xaaladaha heerkulka sare. Waxa kale oo ay ku habboon tahay 240 ℃ iyo 400 ℃ isku darka biphenyl ether iyo noocyada alkyl biphenyl
3,Halbeegyada waxqabadka muhiimka ah
1. Dejinta kulaylka: Qiimaha aysiidhka ≤ 0.5mgKOH/g iyo kaarboonka haraaga ah ≤ 1.0% waa marinnada badbaadada, beddelka ayaa loo baahan yahay haddii uu dhaafo heerarka.
2. Badbaadada Oxidation: Barta toosh ee furan waa ≥ 200 ℃, halka karkarinta bilawga ah ay ka sarreyso heerkulka shaqada ugu badan.
3. Saaxiibtinimada deegaanka: mudnaanta waa in la siiyaa kuwa aan sunta ahayn iyo saliidaha wareejinta kulaylka noolaha (sida nooca diphenyl ether).
4,taxaddarrada xulashada
1. Ka fogow ismaandhaafka:
- Saliidda macdanta looma isticmaali karo hababka gaaska-wejiga, haddii kale waxay u nugul tahay oksaydhka iyo daadinta.
-Nidaamka xiran waxay mamnuucayaan isticmaalka barta karkarinta hoose iyo saliidaha aan kacsanayn.
2. Summada iyo Shahaadaynta:
-Dooro badeecooyinka shahaadaysan si waafaqsan heerka GB23971-2009 oo arag warbixinnada imtixaanka qolo saddexaad.
-Mudnaan sii summadaha bixiya adeegga iibka kadib, sida Saliida Kuleylka Weyn ee Wall iyo Kiimikada Tongfu.
5,Talooyinka dayactirka
Tijaabada joogtada ah: Qiimaha aysiidhka iyo kaarboonka haraaga ah ayaa la tijaabiyaa lixdii biloodba mar, isbeddellada viscosity-ga ayaa la qiimeeyaa sanadkiiba.
Xiritaanka nidaamka: Nidaamyada xiran waxay u baahan yihiin ilaalinta nitrogen, halka nidaamyada furan ay u baahan yihiin wareegyo nadiifin oo gaaban.
