Tshooj 1: Propylene's "Industry Position" - Qhov "Second-nyob rau hauv-Txoj Haujlwm" ntawm Kev Lag Luam Petrochemical
propylene, tshuaj formula C₃H₆, yog ib qho tsis muaj xim, me ntsis qab zib flammable roj ntawm chav tsev kub. Txawm hais tias nws 知名度 qis dua me ntsis ntawm ethylene, "Niam ntawm Kev Lag Luam Petrochemical," hais txog txoj haujlwm ntawm kev lag luam, propylene tuaj yeem suav hais tias yog "thib ob-hauv-Kev txib."
Thoob plaws ntiaj teb, ntau tshaj 140 lab tons ntawm propylene yog tsim txhua xyoo, ntawm uas Tuam Tshoj suav txog ze li ntawm 70 lab tons. Qhov no propylene thaum kawg dhau los ua cov hnab yas hauv koj txhais tes, dashboard hauv koj lub tsheb, txheej rwb thaiv tsev ntawm koj lub tsev tub yees, thiab txawm tias cov fibers ntawm koj cov khaub ncaws.
Yog vim li cas propylene tseem ceeb heev nyob ntawm nws cov tub ntxhais hauv ib "carbon-carbon ob daim ntawv cog lus" (C=C) hauv nws cov molecule. Qhov ob daim ntawv cog lus no ua zoo li "tshuaj tes," tso cai rau nws yooj yim "tuav tes" nrog lwm cov molecules - polymerizing, ntxiv, oxidizing ... hloov mus rau ntau pua thiab ntau txhiab cov khoom.
Tshooj 2: Kev siv ntau tshaj plaws ntawm propylene - Polypropylene (PP), suav txog ze li 70%
2.1 Polypropylene yog dab tsi?
Kev siv ntau tshaj plaws ntawm propylene yog kev tsim cov polypropylene, nrog kev sib faib ntawm kwv yees li 68% -71%.
Polypropylene is one of the five general-purpose plastics, with advantages such as low density, heat resistance, chemical corrosion resistance, and good electrical insulation. Yooj yim hais, nws yog "tag nrho-ib ncig ntawm cov neeg ua si" hauv ntiaj teb plastics.
2.2 Polypropylene siv nyob qhov twg?
Cov kev siv downstream ntawm polypropylene yog dav heev:

Cov tsheb tshiab lub zog yog ib qho ntawm qhov nrawm tshaj plaws - thaj chaw thov rau polypropylene. Hloov kho polypropylene yog feem ntau siv rau tsheb sib sib zog nqus - hloov hlau nrog yas. Rau txhua 100 kg ntawm qhov hnyav, qhov ntau ntawm lub tsheb fais fab tuaj yeem nce li ntawm 10 km. Tam sim no, cov yas siv rau hauv lub tsheb tshiab lub zog tau tshaj 35 kilograms.
Tshooj 3: Qib Thib Ob ntawm Propylene - Siab -Tus nqi- Ntxiv Derivatives
Dhau li ntawm polypropylene, propylene kuj muab tau ntau yam ntawm -tus nqi- ntxiv tshuaj. Txawm hais tias lawv tus kheej cov khoom sib koom tsis loj npaum li ntawm polypropylene, ua ke lawv txhawb nqa "ib nrab" ntawm propylene downstream kev lag luam.
3.1 Propylene Oxide (PO) - Cov Tub Ntxhais Raw Khoom rau Polyurethane
propylene oxide yog qhov thib ob loj tshaj plaws derivative ntawm propylene, nrog rau kev sib faib ntawm kwv yees li 7% -8%.
Nws siv ntau tshaj plaws yog kev tsim cov polyether polyols, uas yog siv los ua 制造 polyurethane (PU) ua npuas ncauj. Polyurethane ua npuas ncauj yog cov npuas dej dawb hauv cov txheej txheej rwb thaiv tsev ntawm cov tub yees, lub tub yees, thiab lub tshuab rhaub dej, thiab nws tseem yog daim txhuam cev mos hauv sofas thiab txaj.
Qhov kawg - siv daim ntawv thov ntawm propylene oxide yog siv nyob rau hauv peb qhov chaw loj: rooj tog, khoom siv hauv tsev, thiab tsheb.
3.2 Acrylonitrile - Los ntawm ABS rau Carbon Fiber
Acrylonitrile tso nyiaj rau kwv yees li 6% -7% ntawm propylene's downstream noj.

Acrylonitrile yog cov khoom siv tseem ceeb rau cov pa roj carbon fiber ntau, thiab cov roj carbon fiber yog cov khoom siv tseem ceeb rau aerospace thiab siab -kawg ntaus pob ncaws pob khoom (xws li lub tsheb kauj vab, nuv ntses rods). Kev lag luam nyob sab Europe thiab Asmeskas yog ntau dua 偏向 cov ntawv thov siab - kawg, thaum Asia - cheeb tsam Pacific yog tus thawj coj los ntawm kev noj cov khoom yas loj.
3.3 Butanol thiab Octanol - Tom qab-the-Scenes Heroes ntawm Coatings thiab Plasticizers
Butanol thiab octanol yog lwm ceg tseem ceeb ntawm propylene, nrog kev sib koom ua ke ntawm kwv yees li 7% -8%.
Butanol thiab octanol feem ntau yog siv los tsim cov acrylates (coatings, adhesives) thiab plasticizers (cov ntaub ntawv uas soften plastics), thiab muaj feem xyuam nrog kev lag luam xws li vaj tse thiab cov khoom yas.
3.4 Acrylic Acid - Los ntawm txheej rau cov ntaub qhwv
Acrylic acid suav txog kwv yees li 4% ntawm propylene noj thiab yog tsim los ntawm catalytic oxidation ntawm propylene.
Nws cov kev siv tseem ceeb suav nrog:
Acrylate txheej:Phab ntsa xim, automotive xim
Superabsorbent Polymer (SAP):Cov khoom siv tseem ceeb rau cov pawm thiab cov ntaub so huv huv
Adhesives:Cov kab xev, daim ntawv lo, siab -sensitive adhesives
3.5 Isopropanol - Ib "Tus Neeg Tuaj Saib Xyuas" rau tshuaj tua kab mob thiab cov kuab tshuaj
Isopropanol yog tsim los ntawm cov dej ncaj qha ntawm propylene thiab feem ntau yog siv los ua:
Solvent:Inks, coatings, hluav taws xob tu
Tshuaj tua kab mob:Lwm txoj hauv kev kho mob cawv (kev xav tau nce ntxiv tom qab kis thoob qhov txhia chaw)
Chemical intermediate:Kev tsim cov acetone, isopropylamine, thiab lwm yam.
3.6 Phenol/Acetone - Raw Materials rau Bisphenol A
propylene reacts nrog benzene los tsim cumene, uas tom qab ntawd oxidized kom tau phenol thiab acetone (tsim ua ke, sib sau ua ke hu ua "phenol-acetone"):
Phenol → Bisphenol A → Epoxy cob, Polycarbonate (PC)
Acetone → Polymethyl methacrylate (PMMA, acrylic iav)
Tshooj 4: Kev Siv Cov propylene tshiab - Cov Cuab Yeej Tshiab rau Kev Loj Hlob Yav Tom Ntej
4.1 POE (Polyolefin Elastomer) - Cov khoom siv tseem ceeb rau Photovoltaic Encapsulation Films
POE yog cov khoom siab tshaj -kawg tau txais los ntawm copolymerization ntawm propylene thiab ethylene, feem ntau yog siv rau photovoltaic encapsulation films (cov khoom ntim rau hnub ci vaj huam sib luag). Nrog rau kev loj hlob tsis tu ncua ntawm lub ntiaj teb photovoltaic ntsia muaj peev xwm, qhov kev thov rau POE tau nce sai heev.
4.2 Lithium roj teeb Separator Zaj duab xis
High-kawg polypropylene yog siv los tsim cov lithium roj teeb cais cov yeeb yaj kiab, uas yog ib qho tseem ceeb ntawm cov roj teeb tsheb tshiab.

Xaus
Los ntawm cov khaubncaws sab nraud povtseg ntawm lub tub yees mus rau lub tsheb bumpers, los ntawm lub qhov ncauj qhov ntswg kho mob mus rau photovoltaic encapsulation films, propylene tau dhau los ua tob rau hauv txhua lub ces kaum ntawm kev lag luam niaj hnub no. Nws tsis yog ib lo lus tshuaj xwb, tab sis yog "pob txha tsis pom" hauv peb lub neej niaj hnub.
Nrog kev nce ntawm kev lag luam tawm tshiab xws li lub zog tshiab tsheb, photovoltaics, thiab semiconductors, propylene tab tom hloov pauv los ntawm "cov khoom siv yas ntau" mus rau "siab- nqi- ntxiv tshuaj zoo." Nyob rau hauv kaum xyoo tom ntej no, leej twg tuaj yeem muaj qhov chaw nyob hauv qhov siab - kawg daim ntawv thov teb ntawm propylene yuav tau txais lub zog siab hauv qhov kev txhim kho kev lag luam no.
