Kev ua haujlwm ntawm cov khoom siv rwb thaiv tsev yog los tiv thaiv ib feem ntawm cov khoom siv hluav taws xob los ntawm kev cuam tshuam hluav taws xob uas muaj peev xwm sib txawv. Yog li ntawd, cov khoom siv rwb thaiv tsev yuav tsum ua ntej muaj kev tiv thaiv hauv av thiab compressive zog, thiab tuaj yeem tiv thaiv kev nyab xeeb xws li hluav taws xob poob siab thiab kev nkag mus. Thib ob, nws muaj qhov kub thiab txias zoo dua los tiv thaiv embrittlement thiab pwm vim yog lub sijhawm ntev overheating; Tsis tas li ntawd, nws tseem yuav tsum muaj kev hloov pauv kub zoo heev, dej thiab xob laim tiv thaiv, muaj kev cuam tshuam siab tawv, thiab yooj yim tsim thiab ua cov cuab yeej siv. Raws li cov kev cai saum toj no, qhov kev ua tau zoo ntawm cov ntaub ntawv rwb thaiv tsev muaj xws li compressive zog, tensile zog, kev faib ua feem, thermal expansion coefficient, thiab lwm yam.
Cov ntaub ntawv rwb thaiv tsev zoo tshaj plaws rau cov khoom siv hluav taws xob tuaj yeem muab faib ua cov khoom siv hluav taws xob tsis muaj hluav taws xob, cov khoom siv hluav taws xob hluav taws xob hluav taws xob, thiab cov khoom siv hluav taws xob sib xyaw ua ke raws li lawv lub cev. Cov ntaub ntawv pov thawj inorganic muaj xws li biotite, asbestos, ntuj marble, pottery, laminated iav, sulfur, thiab lwm yam. Lawv yog siv los ua winding rwb thaiv tsev khaubncaws sab nraud povtseg rau hluav taws xob motors thiab cov khoom siv hauv tsev, lub hauv paus phaj rau lub hwj chim keyboards, thiab composite insulators. Organic chemical rwb thaiv tsev txheej cov ntaub ntawv muaj xws li: cov pos hniav, epoxy resin, vulcanized roj hmab, ntshiab paj rwb xov, ntawv, hemp, polyester, thiab lwm yam. Feem ntau ntawm lawv yog siv nyob rau hauv kev tsim thiab tsim ntawm peb proofing xim, txawv txawv txav rwb thaiv tsev ntaub ntawv rau winding kis kab. , thiab lwm yam. Cov khoom siv rwb thaiv tsev sib xyaw yog ntau yam khoom siv rwb thaiv tsev tsim los ntawm cov khoom siv saum toj no los ntawm kev tsim thiab kev ua, siv los ua lub hauv paus thiab cov khoom siv hauv tsev.
