Kev siv tshwj xeeb thiab kev ua haujlwm ntawm cov roj dimethyl silicone
Dimethyl silicone roj yog cov pob tshab, tsis muaj xim, tsis muaj ntxhiab, tsis qab, thiab tsis yog - kua qaub oily. Nws muaj cov yam ntxwv xws li lub teeb nyem siab, tsis tshua muaj qhov chaw khov, zoo thermal stability, thiab tsis kam mus rau qhov kub thiab txias. Nws tuaj yeem siv tau rau lub sijhawm ntev ntawm qhov kub ntawm qhov kub ntawm -50℃mus rau +180 degree, thiab tuaj yeem ncav cuag 200℃thaum siv tsis muaj huab cua lossis hauv ib puag ncig tsis muaj roj. The oil has very low surface silicone tension, high compressibility, good shear resistance, low viscosity-temperature coefficient, and low dielectric loss; nws yog arc-resistant, corona-resistant, thiab tsis yog{11}}flammable; nws yog hydrophobic thiab noo noo-pov thawj, thiab kuj muaj zoo physiological inertness.
Cov kev siv tshwj xeeb thiab kev ua haujlwm ntawm dimethyl silicone roj yog raws li hauv qab no:
Due to its low surface tension and insolubility in water, vegetable oils, and high-boiling-point mineral oils, dimethyl silicone oil exhibits good chemical stability and is non-toxic. Nws yog dav siv los ua defoamer hauv kev lag luam xws li tshuaj lom neeg, kev kho mob, tshuaj, khoom noj khoom haus, textile, luam ntawv thiab dyeing, thiab papermaking. Ntxiv 10-100 PPM ntawm silicone roj muab cov teebmeem zoo heev.
Vim nws cov khoom tsis yog - nplaum nrog roj hmab, yas, thiab hlau, dimethyl silicone roj yog siv los ua pwm tso tawm tus neeg sawv cev hauv molding thiab ua cov khoom siv roj hmab thiab yas, thiab tseem nyob rau hauv precision casting. Siv nws ua cov pwm tso tawm tus neeg sawv cev tsis tsuas yog ua kom yooj yim demolding tab sis kuj tawm ntawm cov khoom nto huv si, du, thiab nrog cov ntaub ntawv ntshiab.
Siv ib txheej ntawm dimethyl silicone roj rau saum npoo ntawm iav thiab ceramics, ua raws li kev kho cua sov ntawm 250-300 degree, ua ib qho semi- tsis tu ncua tsis muaj dej tsis zoo, pwm-pov thawj, thiab insulating zaj duab xis. Thaum siv los kho cov khoom siv insulating, nws txhim kho lawv cov kev ua haujlwm rwb thaiv tsev; thaum siv los kho cov cuab yeej kho qhov muag, nws tiv thaiv cov lo ntsiab muag thiab prisms los ntawm kev ua pwm; thaum siv los kho cov fwj tshuaj, nws ncua lub txee lub neej ntawm cov tshuaj thiab tiv thaiv kev poob vim adhesion rau lub raj mis phab ntsa; thaum siv los kho qhov chaw ntawm cov duab zaj duab xis, nws muab lubrication, txo kev sib txhuam, thiab ncua cov zaj duab xis lifespan.
Haum raws li lub roj nplua nyeem rau roj hmab thiab yas bearings thiab iav. Nws tseem tuaj yeem siv los ua cov roj nplua nyeem rau kev sib txhuam ntawm cov hlau ntawm qhov kub thiab txias, lossis rau kev sib txhuam ntawm cov hlau thiab lwm yam hlau. Txawm li cas los xij, vim hais tias lub lubricating kev ua tau zoo ntawm methyl silicone roj tsis yog tshwj xeeb zoo nyob rau hauv chav tsev kub, nws yog feem ntau tsis pom zoo raws li ib tug lubricant ntawm hlau nyob rau hauv chav tsev kub.
Nws tuaj yeem siv los ua cov khoom siv ntxiv rau ntau yam ntaub ntawv. Piv txwv li, nws tuaj yeem siv los ua ib qho gloss hauv cov xim. Ntxiv me me ntawm cov roj silicone rau cov xim tuaj yeem tiv thaiv blistering thiab wrinkling, thiab txhim kho cov gloss ntawm cov xim zaj duab xis. Ntxiv me me ntawm cov roj silicone rau number case tuaj yeem txhim kho kev luam ntawv zoo. Ntxiv me me ntawm silicone roj rau polishing roj (xws li automotive varnish) tuaj yeem ua kom gloss, tiv thaiv cov xim zaj duab xis, thiab muab cov dej tsis zoo.
