Faahfaahinta Alaabta

Propylene carbonate waa qayb muhiim ah oo dabiici ah oo si weyn loogu isticmaalo qaybo kala duwan sida warshadaha elektiroonigga ah, warshadaha polymer, warshadaha kiimikada, daabacaadda dharka iyo rinjiyeynta, iyo kuwa kale. Warshadaha elektiroonigga ah, carbonate propylene waxaa loo isticmaalaa qayb muhiim ah oo ka mid ah batariyada lithium-ion ee elektirolytka, taas oo kor u qaadi karta xasilloonida wareegga iyo badbaadada baytariyada. Intaa waxaa dheer, waxaa sidoo kale loo isticmaalaa in lagu soo saaro qalab elektaroonik ah oo tayo sare leh, oo door muhiim ah ka ciyaaraya soo saarista qaybaha elektaroonigga ah. Warshadaha polymer, propylene carbonate waxaa loo isticmaali karaa sida dareere iyo balaastiig loogu talagalay polymers (sida polyurethane, resin epoxy), hagaajinta dabacsanaanta iyo sifooyinka alaabta. Waxa kale oo loo istcimaalaa in lagu soo saaro xabagyada iyo dabaylaha, iyo sidoo kale kala firdhiya daaweeyayaasha resin phenolic iyo midabada koollada biyaha ku milma. Warshadaha kiimikada, carbonate propylene ayaa ah sheyga ugu muhiimsan ee ka samaysan dimethyl carbonate (DMC). Isla mar ahaantaana, waxaa loo isticmaalaa in laga saaro carbon dioxide iyo hydrogen sulfide ee gaaska dabiiciga ah iyo gaaska dildilaaca batroolka, iyada oo door muhiim ah ka ciyaarta sifeynta gaaska. Goobta daabacaadda dharka iyo midabaynta, carbonate propylene waxaa loo isticmaali karaa sidii wakiilka hagaajinta fiilooyinka synthetic. Dhinacyada kale, carbonate propylene waxaa loo isticmaalaa farsamaynta macdanta juqraafiga iyo kimisteriga gorfaynta. Waxaa intaa dheer, waxay sidoo kale bedeli kartaa resin phenolic sida xabagta alwaax.

Taxadarrada badbaadada

Propylene Carbonate waa walax daxalaysa, oo leh koodhka heerka halista ee R36. Waxay u keeni kartaa cuncun indhaha, mareenka neefsiga iyo maqaarka. Inta lagu jiro qalliinka, waxaa lagu talinayaa in la xidho galoofyada ilaalinta ku habboon iyo muraayadaha, iyo in la hubiyo hawo wanaagsan oo deegaanka ah si looga hortago neefsashada gaasaska xanaaqa. Marka la kaydinayo propylene carbonate, waa in la dhigaa meel qabow oo hawo leh, oo ka fog ilaha dabka iyo oksidayaasha, kana fogow iftiinka qorraxda tooska ah iyo xaaladaha qoyan. Sababtoo ah dabeecadda gubanaysa ee carbonate propylene, aagga kaydinta waa in lagu hayaa engegan oo lagu qalabeeyaa qalab dab-damis oo habboon. Haddii ay dhacdo in daadato, isticmaal walxaha aan shaqaynayn (sida cammuudda) si aad u nuugo dareeraha daatay si aad uga fogaato taabashada tooska ah ee maqaarka ama indhaha. Ka dib marka la taabto maqaarka, isla markiiba ku raaci biyo badan oo la tasho dhakhtar; haddii indhaha ay saameeyaan, isla markiiba ku luqluq biyo badan oo raadso gargaar caafimaad.

Kiimikadayada sida aadka ah loo iibiyo waxaa ka mid ah dareerayaasha warshadaha iyo dhexdhexaadiyeyaasha kiimikaad, sida Taxanaha Alcohol, Taxanaha Ether, Esters, Precursor Series, Acid-Ester Solvents, Bacrimiyeyaasha NPK-Biyaha-Milan, iyo Kiimikada kale ee Warshadaha. Alaabooyinkani waxay ka kooban yihiin sahay deggan, nadiifnimo la isku halayn karo, iyo heerar tayo leh oo joogto ah. Weydiinta waa la soo dhawaynayaa.
