Tsawg viscosity methyl silicone roj yog ib yam ntawm cov kua silicone nrog cov yam ntxwv tshwj xeeb, thiab nws cov yam ntxwv tuaj yeem ua tiav raws li hauv qab no
Tsawg nto nro thiab tsawg viscosity
Low viscosity meticone muaj tsawg heev nto nro thiab viscosity, uas tso cai rau nws ntws thiab permeate tau yooj yim rau ntau cov ntawv thov. Cov cuab yeej no tso cai rau methicone los txhim kho cov khoom fluidity thiab uniformity thaum siv los ua ib qho additives hauv coatings, inks, tshuaj pleev ib ce thiab lwm yam lag luam.
Kub thiab kub tsis kam
Methyl silicone roj tuaj yeem siv tau ntev hauv qhov kub ntau ntawm -50 degree C txog 180 degree C, thiab muaj qhov kub thiab txias tsis kam. Nws qhov chaw khov yog feem ntau qis dua -50 degree C, qee qhov ntau yam tuaj yeem ncav cuag -70 degree C, lub sijhawm ntev cia ntawm qhov kub thiab txias, qhov tsos ntawm cov roj, viscosity thiab lwm yam khoom tsis hloov pauv. . Nyob rau tib lub sijhawm, thermal decomposition kub ntawm methyl silicone roj yog siab li 300 degree, evaporation poob yog me me, thiab nws muaj thermal stability zoo heev.
Tshuaj stability thiab hluav taws xob rwb thaiv tsev
Methyl silicone roj muaj tshuaj lom neeg ruaj khov thiab hluav taws xob rwb thaiv tsev. Nws tsis yog volatile, insoluble nyob rau hauv dej, methanol, ethylene glycol thiab lwm yam kuab tshuaj, tab sis yuav miscible nrog benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride los yog kerosene. Tsis tas li ntawd, lub ntim tsis kam ntawm methyl silicone roj tsis hloov nyob rau hauv qhov kub ntawm chav tsev mus rau 130 degree C, uas qhia tau hais tias zoo heev hluav taws xob rwb thaiv tsev zog.
Hydrophobicity thiab physiological inertia
Methyl silicone roj muaj cov khoom zoo hydrophobic, uas tuaj yeem tiv thaiv dej nkag thiab xeb. Nyob rau tib lub sijhawm, nws kuj muaj lub cev tsis muaj zog, tsis muaj tshuaj lom thiab tsis muaj mob rau tib neeg lub cev, yuav tsis ua rau muaj kev tsis haum tshuaj lossis cov teebmeem stimulating, yog li nws yog dav siv hauv kev kho mob, tshuaj pleev ib ce thiab lwm yam.
Lubrication thiab vibration damping zog
Methylsilicone roj kuj muaj cov roj lubrication zoo thiab kev co damping zog, tuaj yeem siv los ua cov roj lubricating, damping roj, roj poob siab thiab lwm yam. Nws cov lubrication kev ua tau zoo yog superior rau ntau cov tsoos lubricants, txo kev sib txhuam thiab hnav, thiab txuas ntxiv lub neej ntawm cov khoom siv. Nyob rau tib lub sijhawm, nws qhov kev vibration damping kev ua tau zoo kuj tuaj yeem nqus tau kev co, tiv thaiv kev vibration propagation, thiab txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm cov khoom siv.
Hauv cov ntsiab lus, tsawg viscosity methicone tau siv dav hauv ntau qhov chaw nrog nws cov khoom tshwj xeeb, muab kev lees paub muaj zog rau kev txhim kho kev ua haujlwm thiab kev ruaj ntseg ntawm ntau yam khoom.
