Ua Cov Ntawv Fluoroplastic Muaj Cov Khoom Siv Plasticizers

Feem ntau, lub phaj fluoroplastic nrog cov yas yog tsau rau hauv qhov nruab nrab ua haujlwm ntev. Lub plasticizer yuav maj mam nqus los ntawm kev ua haujlwm nruab nrab, uas ua rau lub ntim ntawm O-sealing nplhaib kom qis. Thaum O-type yog tas mus li deformed ntau dua 40 feem pua, fluorine Cov roj hmab phaj poob lub peev xwm sealing thiab leaked. Thawj qhov kev ntxhov siab tsim nyob rau hauv cov khoom siv roj hmab ntawm fluoroplastine vim compression deformation, thiab nws yuav maj mam txo nrog kev poob ntawm cov txheej txheem fluoroplastic thiab qhov kub thiab txias yuav ploj mus. Thawj qhov compression uas ua haujlwm qis dua rau kev ua haujlwm qis dua xoom yuav txo qis lossis ploj tag vim qhov kub thiab txias. Nyob rau hauv rooj plaub ntawm -50 ~ -60 degree C, cov khoom siv roj hmab uas tsis tshua muaj siab yuav poob tag nrho nws qhov kev ntxhov siab thaum pib; Txawm hais tias cov khoom siv roj hmab uas tsis muaj qhov kub thiab txias, qhov kev ntxhov siab thawj zaug ntawm lub sijhawm no yuav tsis ntau tshaj qhov kev ntxhov siab ntawm 25 feem pua ​​​​ntawm 20 ° C. Qhov no yog vim qhov pib compression ntawm fluoroplastics nyob ntawm lineflation coefficient. Yog li ntawd, thaum xaiv qhov pib compression ntim, nws yog ib qho tsim nyog los xyuas kom meej tias tseem muaj peev xwm sealing txaus tom qab qhov kev ntxhov siab poob vim qhov poob ntawm cov txheej txheem thiab kub poob. Fluoropia uas ua haujlwm qis dua xoom, them nyiaj tshwj xeeb rau qhov ntsuas rov qab thiab deformation Performance index ntawm cov khoom siv roj hmab. Hauv cov ntsiab lus, cov qauv tsim yuav tsum yog tsim los xyuas kom meej tias cov fluorine daim kab xev tsim nyog kom muaj qhov kub thiab txias ua haujlwm, los yog siv cov ntaub ntawv kub-resistant thiab low-temperature fluoroplastic sheet cov ntaub ntawv kom ntev lub neej kev pab cuam. 3) Lub siab ntawm qhov nruab nrab ua haujlwm siab thiab qhov nruab nrab deformation ua haujlwm ruaj khov yog qhov tseem ceeb uas ua rau muaj qhov tsis zoo ntawm cov fluorine plywood mus tas li. Kev ua haujlwm siab ntawm cov khoom siv hydraulic niaj hnub no nce ntxiv. Ntev-lub sij hawm high-voltage cuam tshuam tuaj yeem ua rau lub cev deformation ntawm fluorine roj hmab mus tas li. Yog li ntawd, thaum tsim, cov ntaub ntawv zoo-resistant roj hmab yuav tsum raug xaiv raws li kev ua haujlwm siab. Qhov siab dua qhov ua haujlwm siab, qhov siab dua qhov hardness thiab siab ua haujlwm ntawm cov khoom siv. Txhawm rau txhim kho qhov tsis kam ntawm cov khoom siv roj hmab fluorine, ua kom cov elasticity ntawm cov khoom (tshwj xeeb tshaj yog elasticity ntawm cov khoom ntawm qhov kub thiab txias), thiab txo qhov deformation mus tas li ntawm cov khoom. Feem ntau, cov qauv ntawm cov khoom yuav tsum tau ntxiv plasticizers.
