Rau Cable Silicone

► Cov hlau thiab cables, cov khoom siv tsheb hauv tsheb tshiab

► 20kg thawv los yog 440kg pallet lub thawv

► Khaws ntawm chav tsev kub hauv qhov cua thiab qhov chaw txias.
► Kev thauj mus los raws li cov tshuaj tsis muaj kev phom sij thiab kom deb ntawm cov pa phem ncaj qha tshav ntuj thiab dej.

► Siab thiab tsis kub tsis kam
Silicone roj hmab polymer molecules yog cov saw hlau tsim los ntawm kev sib hloov Si-0 (silicon-oxygen) daim ntawv cog lus, thiab lawv cov khoom tseem ceeb yog cov molar mass linear polysiloxanes. Txij li Si-0-Si daim ntawv cog lus yog hom kev cog lus yooj yim ntawm nws cov khoom muaj pes tsawg leeg, silicon atoms feem ntau txuas nrog methyl pawg, thiab ib qho me me ntawm cov pab pawg tsis txaus ntseeg tau qhia rau ntawm cov saw hlau sab. Lub zog intermolecular yog me me, cov molecule muaj cov qauv helical, thiab cov methyl pawg tau teem rau sab nraud thiab tuaj yeem tig tau dawb. Si-0-Si daim ntawv cog lus uas tsim cov saw tseem ceeb ntawm polysiloxane yog qhov sib txawv ntawm C-degree daim ntawv cog lus thiab C-0 daim ntawv cog lus ntawm cov khoom sib xyaw polymer. Nws daim ntawv cog lus lub zog yog kwv yees li 1.3 npaug ntawm qhov kawg, thiab lub kaum sab xis thiab daim ntawv cog lus ntev kuj loj dua. Vim nws cov qauv molecular tshwj xeeb, polysiloxane qhia tau tias thermal stability ntau dua, softness, hluav taws xob rwb thaiv tsev thiab tshuaj stability, thiab lwm yam, uas ua rau silicone roj hmab muaj thermal stability zoo dua li lwm cov roj hmab zoo tib yam. Tsis tas li ntawd, piv nrog cov pa roj carbon atoms, silicon atoms muaj cov khoom siv hlau muaj zog dua thiab tsis muaj zog electronegativity, yog li ntawd li 50% ntawm Si-0-Si bonds muaj nyob rau hauv daim ntawv ntawm ionic bonds.
 

► Thaum tshav kub kub tsis kam
Silicone roj hmab muaj qhov kub zoo dua li cov roj hmab zoo tib yam. Nws tuaj yeem siv tas li ntawm 150 degree yam tsis muaj kev hloov pauv; nws tuaj yeem siv tsis tu ncua rau 10, 000 teev ntawm 200 degree ; Nws tseem tuaj yeem siv rau lub sijhawm ntawm 350 degree. Thaum hlawv, nws tsim cov silica tsis-flammable thiab nws tus kheej tua, tso carbon dioxide thiab dej, thiab muaj toxicity tsawg heev. Nws yog dav siv nyob rau hauv lub sij hawm yuav tsum tau tshav kub tsis kam: thermos seals, siab cooker rings, tshav kub-resistant handles.
 

► Kub kub stability
Qhov tseem ceeb tshaj plaws ntawm cov roj hmab silicone yog nws qhov kub thiab txias, uas tuaj yeem siv tau ntev hauv ib puag ncig nrog huab cua ntawm 180 degree. Yog hais tias tsim nyog muab tub lim thiab kub-kub additives raug xaiv, nws cov kev khiav hauj lwm kub yuav siab li 375 degree, thiab nws muaj peev xwm tiv taus instantaneous kub ntawm ob peb txhiab degrees Celsius. Nws yog kwv yees tias lub neej kev pab cuam ntawm silicone roj hmab zoo tib yam tuaj yeem ncav cuag 20 xyoo ntawm 120 degree thiab 5 xyoo ntawm 150 degree.
