Cov Khoom Siv Nias (PPSU Khoom Siv)Ua lub luag haujlwm tseem ceeb hauv kev xa cov dej tsis muaj xeb thoob plaws EU. PPSU tiv taus qhov kub txog li 207 ° C thiab tiv taus kev puas tsuaj ntawm cov tshuaj lom neeg. Cov qauv kwv yees thiab kev xeem laus lees paub tias cov khoom siv no tuaj yeem muab kev xa dej nyab xeeb thiab txhim khu kev qha rau ntau tshaj 50 xyoo, txawm tias nyob rau hauv ib puag ncig hnyav.
Cov Ntsiab Lus Tseem Ceeb
- PPSU cov khoom siv niastiv taus kev xeb thiab kev puas tsuaj los ntawm tshuaj lom neeg, ua kom muaj kev nyab xeeb thiab kav ntev ntawm cov dej tsis muaj xeb lossis xau.
- Cov khoom siv no ua tau raws li cov qauv EU nruj, ua kom dej haus huv thiab tsis muaj cov tshuaj lom hauv tsev, cov lag luam, thiab cov tsev pej xeem.
- Kev teeb tsa yog ceev thiab tsim nyog nrog PPSU cov khoom siv nias, txo lub sijhawm ua haujlwm thiab cov nqi kho thaum txhim kho cov dej zoo.
Cov Khoom Siv Nias (PPSU): Kev Tiv Thaiv Kev Sib Tsoo thiab Kev Ua Raws Cai ntawm EU
Cov Khoom Siv Xovxwm PPSU Yog Dab Tsi?
PPSU cov khoom siv niassiv polyphenylsulfone, ib hom yas ua tau zoo, los txuas cov kav dej hauv cov tshuab dej. Cov chaw tsim khoom tsim cov khoom siv no rau kev teeb tsa sai thiab ruaj ntseg. Cov khoom siv siv lub cuab yeej nias los tsim lub foob tsis xau. Ntau tus engineers xaiv lawv rau cov haujlwm plumbing vim tias lawv tsis xeb lossis corrode. PPSU nias fittings muab lwm txoj hauv kev sib dua li cov khoom siv hlau. Lawv qhov chaw sab hauv du pab tswj cov dej ntws thiab txo qhov kev pheej hmoo ntawm kev sib sau ua ke. Cov yam ntxwv no ua rau lawv yog qhov kev xaiv nrov hauv cov khoom siv dej niaj hnub.
Cov Khoom Siv PPSU Tiv Thaiv Kev Xeb Li Cas
Cov khoom siv PPSU sawv tawm rau nws lub peev xwm los tiv taus xeb hauv cov dej. Nws cov qauv molecular muaj cov saw hlau phenylene aromatic thiab sulfone pawg. Cov yam ntxwv no muab PPSU kev ruaj khov tshuaj lom neeg siab thiab tiv taus rau ntau yam pH, los ntawm acidic mus rau alkaline. Kev tshawb fawb lees paub tias PPSU tswj nws lub zog thiab cov duab txawm tias thaum raug rau cov tshuaj lom neeg hnyav thiab kub siab. Dej chlorinated, feem ntau siv rau kev tua kab mob, tuaj yeem ua puas ntau cov ntaub ntawv. Txawm li cas los xij, PPSU tiv taus kev puas tsuaj los ntawm chlorine, khaws nws lub zog kho tshuab dhau sijhawm. Cov yam ntxwv no ua rauCov Khoom Siv Nias (PPSU Khoom Siv)ib qho kev daws teeb meem txhim khu kev qha rau cov kab ke dej uas ntsib cov dej hnyav. Tsis zoo li cov hlau, PPSU tsis ua tshuaj nrog dej lossis cov tshuaj tua kab mob, yog li nws tiv thaiv kev xau thiab ua kom lub cev siv tau ntev.
