Silicone roj yog siv dav hauv cov nplaum. Thiab vim nws cov khoom tshwj xeeb, tau dhau los ua ib qho tseem ceeb ntxiv rau ntau yam nplaum.
Silicone roj tuaj yeem siv los ua cov yas yas thiab ntxiv rau cov nplaum xws li silicone sealants thiab epoxy adhesives. Nyob rau hauv silicone sealants, dimethyl silicone roj feem ntau yog siv los ua ib tug plasticizer thiab diluent vim nws zoo compatibility nrog lub hauv paus polymers, raws li zoo raws li nws odorless, non-toxic, non-volatile, thiab chemically ruaj khov zog. Nws qhov sib ntxiv tuaj yeem kho cov viscosity ntawm lub sealant, txhim kho kev tsim kho fluidity thiab lubricity ntawm cov khoom siv, yog li txhim kho cov kev ua tau zoo ntawm cov nplaum nplaum, xws li kev cuam tshuam, qaug zog, thiab lwm yam.
Qhov sib ntxiv ntawm silicone roj hauv epoxy nplaum tuaj yeem txhim kho nws qhov yooj yim thiab kev laus ua haujlwm. Silicon oxygen bonds hauv silicone roj molecules muaj kev ruaj ntseg thiab tuaj yeem tiv taus qhov yaig ntawm epoxy adhesives los ntawm ib puag ncig sab nraud, txuas ntxiv lawv lub neej kev pab cuam. Lub caij no, cov roj silicone tseem tuaj yeem txhim kho cov dej tsis kam ntawm epoxy nplaum thiab tiv thaiv kom tsis txhob ya raws los ntawm kev puas tsuaj rau nws cov khoom. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias ntau ntxiv ntawm silicone roj yuav txo tau lub zog thiab kub tsis kam ntawm epoxy nplaum. Yog li ntawd, hauv kev siv tswv yim, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog nws qhov zoo thiab qhov tsis zoo thiab ntxiv rau hauv qhov nruab nrab.
Tsis tas li ntawd, cov roj silicone tseem tuaj yeem siv los ua cov khoom muaj txiaj ntsig zoo hauv cov ntawv tiv thaiv cov kab mob, tsim nrog cov roj dimethyl silicone uas muaj cov pab pawg ua haujlwm silicon ua lub hauv paus polymer. Nyob rau hauv qhov kev txiav txim ntawm crosslinking agents thiab catalysts, nws yog hloov dua siab tshiab rau hauv ib nrab crosslinked polysiloxane zaj duab xis nrog anti-adhesive zog los ntawm condensation los yog ntxiv cov tshuaj tiv thaiv. Tus neeg sawv cev tiv thaiv no yog nyob rau hauv daim ntawv ntawm cov roj silicone ua ntej kho, thiab tom qab kho, nws dhau los ua cov roj hmab zoo li elastic zaj duab xis nrog cov nyhuv zoo los tiv thaiv.
Zuag qhia tag nrho, daim ntawv thov ntawm cov roj silicone hauv cov nplaum muaj ntau yam zoo, tab sis nws kuj yuav tsum tau xaiv thiab kho raws li qhov xav tau tiag tiag.
