Horumarka Qolka- Heerkulka Tignoolajiyada Dib-u-warshadaynta Silikoon Lagu daabacay Sayniska

2026,08,04

Erayada furaha : Dib-u-warshadaynta silikoon, dhaqaalaha wareegtada, depolymerization polysiloxane, Ga/BCl₃ kicinta

Jumlada Muhiimka ah : Koox cilmi baaris caalami ah ayaa soo saartay Ga / BCl₃ nidaamka catalytic iskaashi awood u dhow-qolka-heerkulka (40°C) depolymerization qashinka silikon cross-linked leh> 90% dhalidda, tallaabo weyn ee dhaqaalaha wareeg silikoon.

Daraasad taariikhi ah oo lagu daabacay Sayniska Agoosto 2, 2026, ayaa shaaca ka qaaday tignoolajiyada dib-u-warshadaynta silikoonka heerkulka-kacaanka ah. Cilmi-baarayaal ka kala socda MIT, Tsinghua University, iyo Wacker Chemie waxay soo saareen gallium (Ga) iyo boron trichloride (BCl₃) nidaamka catalytic synergistic catalytic kaas oo depolymerizes qashinka silikoonka ee isku-xiran (caag, saliid, iyo elastomers) dhexda chlorosilane-qiimaha sare ee 40 ° C cadaadiska atmosphes Nidaamku wuxuu gaaraa> 90% hufnaanta beddelka, isagoo wax ka qabanaya caqabad warshadeed oo dheer: Qaab dhismeedka silikoon ee aadka u xasilloon ee isku-xiran ayaa ka dhigaya dib-u-warshadaynta dhaqameed mid xoog leh iyo wax-soo-saar hoose. Horumarkaani waxa uu sahlayaa dib u warshadaynta wareegyada xiran ee qashinka silikoonka, yaraynta ku tiirsanaanta alaabta ceeriin ee quartz iyo jarida qiiqa kaarboonka 65% marka loo eego wax soo saarka caadiga ah. Dhirta tijaabada ganacsiga ayaa loo qorsheeyay inay ka bilaabato Jarmalka iyo Shiinaha Q1 2027.
