Thaum lub cev muaj zog ntawm cov tsheb hluav taws xob tshiab ntau tshaj 20,000 RPM, cov khoom siv roj av tsis txaus ntseeg. (Ppdi) Raws li cov khoom siv ntawm cov tseem ceeb "nyob rau hauv lub teb kub siab dua lossis muaj kev sib luag ntawm lub zog loj dua qub, muaj kev sib raug zoo ntawm lub zog tshiab, kev tshawb fawb ntse yog rov kho dua lub Underlying logic ntawm thoob ntiaj teb siab {{}}}}}}} Cov ntaub ntawv kev lag luam.
1. Kev Lag Luam Kev Loj Hlob: Lub "triple resonance" ntawm thev naus laus zis kev tiv thaiv thiab kev tiv thaiv kev tiv thaiv thiab ib puag ncig kev tiv thaiv thiab ib puag ncig kev tiv thaiv thiab kev tiv thaiv ib puag ncig
1. High {{{{{}}}}}}} Cov Khoom Siv Hluav Taws Xob "Rigid Xav Tau" rau PPDI Cov Ntaub Ntawv
Lub ntiaj teb tsim kev lag luam tau nrawm nrawm rau "siab {{}}}}}}
Lub zog hluav taws xob tshiab: Kev nce hauv lub tsheb ua kom muaj zog ua rau lub pob txha winding kub kom tau dhau 180 degree. Tsoos MDI / TDI Polyurethane yog ib qho yooj yim los soften thiab deform, thaum lub sij hawm ppdi tuaj yeem ua haujlwm stably mus rau 220 degree, thiab kev ua kom qaug zog lub neej tau nce los ntawm 3 zaug. It has been used in Tesla Model S Plaid, BYD e platform 3.0 and other high-end models.
Kev siv neeg hlau: cov khoom sib koom tes yuav tsum tau walland siab - zaus kev co thiab siab {1} kev sib txhuam kub. PPDI Elastomers tau dhau los ua "cov khoom siv ntawm kev xaiv" rau cov roj teeb liab ntawm Abb, tsawg dua los yog sib npaug ntawm 5%) thiab siab dua lossis sib npaug los yog sib npaug rau 60%).
Roj thiab roj: downhole cov cuab yeej yuav tsum tau tiv thaiv kev kub siab ntawm 300℃thiab hss / cos 腐蚀 corrosion. PPDI cov ntaub ntawv raug hloov kho los ntawm kev ntxiv nano - alumina, uas nce lub neej ncua rau ntau tshaj 2 zaug uas cov khoom siv.
2. Cov kev sib tsoo thev naus laus zis: lub leap ntawm "kuaj" rau "lag luam"
Kev ua lag luam ntawm ppdi polyurethane elastomers tau txwv los ntawm ob qho teeb meem loj:
Siab tus nqi ntawm raw cov ntaub ntawv: tus nqi ntawm ppdi monomers yog 3-5 zaug uas ntawm MDI, thiab nws tau ntev monopolized los ntawm cov neeg loj heev xws li BASF thiab TEASTRO.;
Cov txheej txheem yog qhov nyuaj: cov tshuaj tiv thaiv kub (120-150 degree) thiab qhov ntau ntawm cov tshuaj tua kab, txwv tsis pub nws yooj yim los tsim cov khoom siv gelation.
Nyob rau hauv xyoo tsis ntev los no, thev naus laus zis tau raug nqi raug nqi txo thiab cov txiaj ntsig zoo:
Zosization ntawm raw cov ntaub ntawv: Tuam Tshoj WANHUA Tshuaj Yuav Tsum Tau Loj {| Monomers nyob rau hauv 2023, nrog 40% tus nqi qis dua txawv teb chaws, rhuav cov thoob ntiaj teb monopoly;
Cov txheej txheem Innessation: Bayer, Tebchaws Yelemees, tau tsim "txuas ntxiv cov tshuaj tiv thaiv lub sijhawm los ntawm 8 teev mus rau 2 teev thiab nce ntxiv rau ntau tshaj 95%.;
Additive kev ua kom zoo: Toray ntawm Nyij Pooj uas tau qhia txog Epoxy Resin Crosslinking tus neeg sawv cev los ntawm lwm cov khoom siv 20℃tsis muaj post- vefolanization kev kho mob.
3. Kev tiv thaiv kev tiv thaiv ib puag ncig: hloov kho tshiab los ntawm "Kev Kho Mob Yas" rau "Kev Lom Zem"
Ntiaj teb cov kev tiv thaiv muaj kev tiv thaiv, txhawb nqa ppdi - befleated cov hlau thiab polycyclic aromatic hydrocarbons (PAHS).:
EU ncav cuag cov kev cai tswj hwm: los ntawm 2025, Elastomers muaj cov txhuas thiab cadmium yuav raug txwv tsis pub siv hauv cov khoom pib. PPDI cov ntaub ntawv tau dhau los ua thawj qhov kev xaiv rau kev ua raws li vim tsis - cov tshuaj lom thiab ib puag ncig cov phooj ywg.;
Tuam Tshoj "Girbon ob lub hom phiaj: nws yuav tsum tau tias cov pa roj teeb rau ntawm lub neej tawm ntawm lub neej ua haujlwm tshiab (60% qis dua li cov hlau) thiab lub neej ntev (txo cov zaus ntawm kev hloov).;
Cov Qauv Lag Luam: Qee cov tuam txhab (xws li xws li lub cav hluav taws xob hauv Tebchaws Meskas) {}}}} hom elastomers, nrog cov peev txheej siv ntau dua 90%
