Lub Plaub Hlis 10-13, 2014, Qingdao tau nyob rau lub caij nplooj ntoo hlav sov thiab muaj huab cua zoo rau lub hiav txwv. Cov tub ntxhais kawm los ntawm Taiwan, Philippines, Beijing, Shanghai, hebei, henan, chongqing, zhuhai, liuzhou, jinan, zibo thiab Qingdao ua tiav qib 13th QTG chia kev kawm tiav nrog kev txaus siab tag nrho. Kev kawm paub qhov kev xav yooj yim ntawm polyurea, cov cuab yeej txau, thiab xyaum lub ru tsev cog afforestation polyurea dej tsis ua haujlwm, impermeable, tiv taus cov ceg ntoo ua cov txheej kev tsim kho.
Qingdao tsev kawm ntawv qib siab ntawm kev tshawb fawb thiab thev naus laus zis ntawm Kev Tshaj Tawm Kev Kawm Txuj Ci (Qtech Kev Kawm Pab Pawg, xa mus rau QTG), yog tus tsim lub tshuab polyurea hauv Tuam Tshoj, tus xibfwb huang microwave hauv beijing-shanghai high-speed railway kev tsim kho chaw hauv 2009, tau kom deb li deb. tuav 13 lub sijhawm, rau the Beijing-shanghai high-speed railway, shanghai-hangzhou high-speed railway, Shi Wugao hlau, Qingdao bay choj, choj hong kong-zhuhai-macao thiab lwm lub teb chaws tseem ceeb tiv thaiv polyurea qhov project, faus ntau ntawm cov kws tshaj lij thiab cov neeg ua haujlwm; Nyob rau tib lub sijhawm ntawd, nws tseem muab txoj kev kawm thiab kev hloov pauv rau cov phooj ywg thoob ntiaj teb uas xav paub cov txuj ci kev paub ntawm polyurea thev naus laus zis thoob ntiaj teb. Qhia ntau ntxiv, nws muaj kev txhawj xeeb heev los ntawm polyurea kev lag luam hauv tsev thiab txawv teb chaws. Qhov nrov siab thiab ntau tus neeg koom nrog tau dhau ntawm PDA hauv Asmeskas thiab Europe, thiab dhau los ua Suav PDA tsim nyog nws lub npe.
Txoj kev cob qhia no tau hloov kho thiab ntxiv cov ntaub ntawv cob qhia. Raws li cov cai ntawm cov tub ntxhais kawm thiab peb qhov kev paub dhau los, ntawm lub hauv paus ntawm thawj qhov kev xav thiab kev qhia, peb ua tib zoo npaj thiab npaj, ntxiv ntau cov kev tshawb fawb txog niaj hnub tam sim no thiab cov xwm txheej zoo kawg, uas yog phau ntawv muaj cov tshuaj txau polyurea elastomer tshuab los ntawm cov xibfwb. huang, thiab xyuam xim ntxiv rau kev ua haujlwm ntawm polyurea thev naus laus zis. Cov ntawv luam tawm tshiab suav nrog lub hauv paus ntsiab lus ntawm "zero elongation fracture" thiab ntsuas radical; Qhob pas dej ua ke pinhole, kho cov teeb meem ceev; Kawm ntawm ultra-ntev durability ntawm polyurea cov ntaub ntawv; Yim txoj kev rau kev txheeb xyuas sai ntawm qhov tseeb lossis cuav polyurea; Kev daws ntawm kev nplaum ntawm refractory hlau substrates; Kev tsom xam thiab cov ntsiab lus ntawm qhov ua tsis ua haujlwm ntawm polyurea project; Mus ntsib cov keeb kwm kev tsim khoom siv polyurea thev naus laus zis los ntawm H3500 mus rau phx-40 tiam hydraulic lub cav loj thiab rab phom txau.
