Daim Ntawv Thov Txias Hom Optical Cable Filling Gel
Khoom Taw Qhia
Khoom taw qhia: Optical cable filling gel txais GTL txheej txheem roj thiab cov khoom siv hluav taws xob siab molecular ua cov ntaub ntawv tseem ceeb. Lawv tau ua ke ua cov mos mos, tsis muaj viscosity, siab thixotropic Performance index, tsis muaj xim pob tshab filling gel los ntawm cov txheej txheem ntau lawm uas nws cov yam ntxwv muaj dej tsis zoo, kev ua haujlwm zoo heev thiab cov khoom kub thiab qis. Nws tuaj yeem ua kom mos hauv qab -40 ℃ thiab tsis muaj dej ntws ntawm qhov kub ntawm 80 ℃. Cov txheej txheem sau yog yooj yim uas tuaj yeem sau rau ntawm qhov kub thiab txias, tshwj xeeb tshaj yog tsim rau cov hlua khi thiab cov tub ntxhais cable. Raws li ntau yam kev xav tau ntawm cov neeg siv khoom, cov txheej txheem kev ntsuas ntawm viscosity, nkag mus, thixotropic thiab lwm yam uas tuaj yeem hloov kho thiaj li ua tau raws li cov txheej txheem filling.
Technical parameters
Txias Daim Ntawv Thov Optical Cable Filling Gel Technical Specification
1 、 Cov Lus Qhia Tshwj Xeeb
Filling gel yog xav tau los ua homogeneous, hydrogen absorption, thiab tsis suav nrog cov hmoov av, hlau hais, thiab lwm yam impurities. Nws yuav tsum tsis pom pom huab cua npuas, thiab cov pwm yuav tsum tsis muaj zaub mov. Filling gel yuav tsum tsis muaj tshuaj lom, tsis muaj stimulation rau ntawm daim tawv nqaij.
