1. Hluav taws xob muaj nuj nqi
Kev ua haujlwm zoo --- feem ntau cov khoom lag luam xav tau kev ua haujlwm zoo dua qub, thiab ib qho khoom lag luam xav tau qee qhov kev tiv thaiv.
Rwb thaiv tsev muaj nuj nqi --- rwb thaiv tsev tsis kam, dielectric coefficient, dielectric poob, hluav taws xob tsis kam, thiab lwm yam.
Cov yam ntxwv kis tau tus mob xa mus rau cov yam ntxwv sib kis tau zoo, cov yam ntxwv tiv thaiv kev cuam tshuam, thiab lwm yam.
2. Mechanical muaj nuj nqi
Nws hais txog lub zog tensile, elongation, dabtsi yog khoov, elasticity, saj zawg zog, poob siab tsis kam, abrasion tsis kam thiab mechanical impact resistance.
3. Thermal muaj nuj nqi
Nws yog hais txog qhov ntsuas kub ntawm cov khoom lag luam, kev ua haujlwm kub, cua sov thiab cua sov dissipation yam ntxwv, lub peev xwm nqa tam sim no, luv luv Circuit Court thiab overload muaj peev xwm, thermal deformation thiab thermal shock resistance peev xwm ntawm cov khoom siv, thermal expansion ntawm cov ntaub ntawv, thiab dripping. kev ua haujlwm ntawm cov khoom siv impregnated lossis coated ntawm cov xov hlau thiab cables siv rau kev xa hluav taws xob.
4. Corrosion kuj thiab huab cua tsis kam
Nws hais txog electrochemical corrosion kuj, lom thiab kab mob corrosion kuj, tshuaj lom neeg (roj, acid, alkali, tshuaj hnyav, thiab lwm yam) corrosion kuj, ntsev pos huab, lub teeb tsis kam, txias tsis kam, pwm kuj, ya raws, thiab lwm yam.
5. Kev laus ua haujlwm
Nws hais txog lub peev xwm ntawm cov khoom lag luam thiab lawv cov khoom siv los ua raws li lawv cov haujlwm qub nyob rau hauv cov txiaj ntsig ntawm kev ntxhov siab, hluav taws xob, kev ntxhov siab thermal thiab lwm yam sab nraud, los yog nyob rau hauv cov nyhuv ntawm sab nraud climatic tej yam kev mob.
6. Lwm cov haujlwm
Nws suav nrog cov yam ntxwv ntawm qee cov ntaub ntawv (xws li hardness thiab creep ntawm hlau cov ntaub ntawv, thiab compatibility ntawm polymer cov ntaub ntawv) thiab ib co tshwj xeeb daim ntawv thov yam ntxwv ntawm cov khoom (xws li tsis nplaim retardancy, atomic hluav taws xob tsis kam, kab tom, ncua kev sib kis, thiab lub zog. damping).
