Muaj qhov sib txawv tseem ceeb ntawm phenyl silicone roj thiab methyl silicone roj hauv ntau yam, thiab cov hauv qab no yog cov ncauj lus kom ntxaws txog qhov sib txawv ntawm ob:
I. Molecular qauv thiab tshuaj muaj zog
Phenyl silicone roj: nws cov qauv molecular muaj phenyl, silicone bonds thiab acyl oxide, lub molecule yog tus loj thiab ruaj khov qauv, nrog zoo heev tshuaj stability. Lub siab viscosity thiab zoo brushability ntawm phenyl silicone roj ua rau nws insensitive rau kub thiab oxygen, uas qhia tau hais tias zoo kub kuj, hluav taws xob kuj, lubrication thiab solubility nyob rau hauv cov organic solvents.
Methyl silicone roj: lub molecule muaj tsuas yog methyl thiab silicone bonds, lub luj molecular yog me me, cov qauv molecular kuj yooj yim, yog li nws stability yog phem tshaj li phenyl silicone roj. Methyl silicone roj muaj cov cua kub zoo heev, hluav taws xob rwb thaiv tsev, huab cua tsis kam, hydrophobicity, physiological inertia thiab me me nto nro, tab sis nws viscosity kub coefficient yog tsawg, siab tsis kam mus compressibility.
2. Lub cev muaj zog
Phenyl silicone roj: feem ntau tsis muaj xim rau daj pob tshab roj, tsis muaj cov khoom tsis huv, nrog lub siab viscosity kub coefficient, tsis tshua muaj khov taw tes thiab flash point. Nrog rau qhov nce ntawm molar feem ntawm phenyl, nws qhov kub tsis kam, hluav taws xob tiv thaiv, lubricity thiab solubility hauv cov kuab tshuaj organic tau txhim kho, tab sis nws qhov kub tsis kam yuav raug txo.
Methylsilicone roj: kuj tsis muaj xim pob tshab kua nplaum, tab sis nws cov viscosity tsawg, lubrication zoo heev. Methicone yog insoluble nyob rau hauv polar solvents xws li dej, methanol thiab ethylene glycol, tab sis nws yog miscible nrog non-polar solvents xws li benzene, dimethyl ether, methyl ethyl ketone, carbon tetrachloride los yog kerosene.
3. Daim ntawv thov teb
Phenyl silicone roj: Vim nws cov tshuaj zoo heev ruaj khov thiab lub cev muaj zog, phenyl silicone roj yog dav siv hauv tshuaj pleev ib ce, khoom tu tawv nqaij, tu plaub hau thiab tshuaj. Tsis tas li ntawd, nws kuj tseem siv tau los ua cov kub thiab hluav taws xob resistant silicone roj hmab molding raw cov ntaub ntawv, ntaub xov cov neeg ua hauj lwm thiab cov khoom ntim LED.
Methyl silicone roj: feem ntau yog siv rau hauv lubricants, sealants, industrial coatings thiab lwm yam teb. Nws kuj yog siv dav hauv cov khoom siv hluav taws xob, khoom siv hauv tsev, kev tsim hluav taws xob, kev thauj mus los, petrochemical, textile printing thiab dyeing industries. Methylsilicone roj kuj tseem siv tau los ua defoamer, defilm tus neeg sawv cev thiab ntxiv rau cov xim thiab cov tshuaj pleev ib ce txhua hnub.
Hauv cov ntsiab lus, muaj qhov sib txawv tseem ceeb ntawm phenyl silicone roj thiab methyl silicone roj hauv cov qauv molecular, cov khoom siv tshuaj, lub cev thiab daim ntawv thov. Thaum xaiv siv, kev xaiv tsim nyog yuav tsum tau ua raws li cov kev xav tau tshwj xeeb thiab qhov xwm txheej ntawm cov khoom.
