Propylene oxide waxaa loo qaataa inay tahay dhexdhexaad wax soo saarka polyurethane, antifreeze iyo kiimikooyinka kale ee warshadaha.Mitirka cufnaanta dhuumahawaxaa lagu dhex darayaa khadka wax soo saarka ee xarunta wax soo saarka oksaydhka propylene -- Warshadda Oxide Propylene si loo xakameeyo falgalka kiimikada, kaas oo hal fal-celin oo muhiim ahhaydarojiin peroxide (H₂O₂)waxay la falgashaa propylene iyadoo ay joogaan kiciyaha si uu u sameeyo propylene oxide.
Heerka falcelinta, tayada badeecada iyo waxtarka guud dhammaantood waa la hagaajin karaa iyada oo loo marayoMitirka fiirsashada haydarojiin peroxideMarxalado kala duwan oo wax soo saar ah. Falcelinta ugu weyn waxay ku tiirsan tahay falgalka epoksaydhka, halkaas oo propylene ay la falgasho hydrogen peroxide (H₂O₂) iyadoo ay joogaan kiciyaha (badanaa kiciyaha ku salaysan tungstate ama molybdate) si uu u sameeyo propylene oxide (C₃H₆O) iyo biyo (H₂O).
Cabbiraadda Dhibcaha Soo Saarista Propylene Oxide
Meelaha muhiimka ah ee lagu cabbiro waxaa ka mid ah gelitaanka walxaha ceeriin, weelka falcelinta, marxaladda kala-soocidda iyo soo kabashada, iwm. Meesha laga galo quudinta haydrojiin peroxide waa meel lagama maarmaan ah si loo hubiyo qeexitaannada loo baahan yahay. Guud ahaan, haydrojiin peroxide waxaa lagu kaydiyaa qaab xooggan, waxaana loo baahan yahay in la qaso ka hor inta aan la sii farsamayn ama la falgelin kiimikooyinka kale.
Kadib u tag weelka falcelinta ama falgalka falgalka. Kani waa meel kale oo lagu cabbiroCabbirka fiirsashada haydarojiin peroxidesi falcelintu u socoto sidii la filayay. Mitirka cufnaanta habka khadka gudahaama dareemayaal kale ayaa awood u leh inay ku rakibaan meesha laga soo saaro falgalka si ay ula socdaan fiirsashada waqtiga-dhabta ah ee hydrogen peroxide marka ay la falgasho propylene.mitirka cufnaanta khadka tooska ahWaxay suurtogal ka dhigaysaa in la hagaajiyo firfircoonida hydrogen peroxide si loo kormeero si joogto ah. Haddii fiirsashada ay si dhakhso ah hoos ugu dhacdo ama falcelintu aysan horay u socon sidii la filayay, waxaa lagama maarmaan ah in la hagaajiyo socodka hydrogen peroxide ee ku jira fal-galiyaha.
Falcelinta kadib waxaa ku jira kala soocidda iyo nadiifinta propylene oxide iyo waxyaabaha ka soo baxa, sida biyaha iyo hydrogen peroxide-ka aan falcelinta lahayn. Tusaale ahaan, hydrogen peroxide-ka heerka sare ah wuxuu khatar ku yahay waaritaanka deegaanka iyo badbaadada aadanaha. Cabbirka isku-darka saxda ah wuxuu suurtogal ka dhigayaa in la cabbiro oo la farsameeyo si loo waafajiyo sharciyada iyo qawaaniinta.
Nidaamyada cabbiraadda caqliga leh ee meelaha muhiimka ah ee geeddi-socodka waxay wax badan ka caawiyaan hagaajinta wax-soo-saarka. Adeegsiga teknoolojiyada horumarsan sidaDensitometers-ka khadka tooska ah, spectrophotometers, iyo hababka titration waxay u oggolaanayaan la socodka waqtiga-dhabta ah, cabbiraadda saxda ah ee uruurinta, iyo xakamaynta habka oo wanaagsan, taasoo ugu dambeyntii horseedda wax-soo-saar sare iyo hawlgallo ammaan ah.
