粘度 Viscosity

液體或氣體對流動所表現(xiàn)的阻力。粘性的大小用粘度表示。單位：1Pa.s=1,000mPa.s=1,000cps

The resistance of a liquid or gas to flow. The size of viscosity is expressed by viscosity.

Setting：1Pa.s=1,000mPa.s=1,000cps.

邵氏硬度 Shore Hardness

常用來表征材料的一種硬度標(biāo)準(zhǔn)。其中，Shore A型適用于一般橡膠、合成橡膠，Shore C型適用于含有發(fā)泡劑制成的微孔材料，Shore D型適用于一般硬橡膠、樹脂、亞克力、玻璃等

A hardness standard commonly used to characterize materials. Among them, shore A is suitable for general rubber and synthetic rubber, shore C is suitable for microporous materials made of foaming agent, and shore D is suitable for general hard rubber, resin, acrylic, glass, etc.

比重 Specific Gravity

比重也稱相對密度。是指夜、固體相對于標(biāo)準(zhǔn)壓力和溫度3.98°C下的純水（999.972kg/m3）密度的比值

Specific gravity is also called relative density. It refers to pure water (999.972kg/m) of liquid and solid at 3.98 ° C relative to standard pressure and temperature 3） Density ratio.

拉伸強度 Tensile strength

是指在拉伸試驗中，試樣直至斷裂為止所受的最大拉伸應(yīng)力及為拉伸強度，其結(jié)果用MPa表示

It refers to the maximum tensile stress and tensile strength of the sample until fracture in the tensile test, and the result is expressed in MPa.

伸長率 Elongation

是指試樣在斷裂時的位移值于原長的比值，以百分比表示

It refers to the ratio of the displacement value of the sample at fracture to the original length, expressed in percentage.

抗撕強度 Tear Strength

是指將帶有裂口的長條形片樣的兩“褲腿”經(jīng)受拉力試驗機的拉伸，測得完全撕裂時所受的最大力，除以樣片的厚度，單位為KN/m

It refers to the maximum force on the two "trouser legs" of the long strip sample with cracks under the tension of the tensile testing machine and measured when it is completely torn, divided by the thickness of the sample, with the unit of kn / m.

表干時間 Tack-free time

單組分室溫硫化硅橡膠暴露在大氣環(huán)境里的固化過程中，用手指觸摸表面，黏性消失，不黏手的時間

When RTV silicone rubber is exposed to atmospheric environment and cured,the viscidity disappears and the time of non-sticking hands is reached by touching the surface with fingers.

操作時間 tack-free Time

加成型液體硅橡膠與固化劑或催化劑混合后，在一定的時間內(nèi)粘度增長至膠條失去流動性的這段時間叫操作時間，也稱工作時間

After the reinforced liquid silicone rubber is mixed with curing agent or catalyst, the time when the viscosity increases to the time when the adhesive strip loses fluidity within a certain period of time is called operation time, also known as working time.

固化時間 Curing Time

加成型液體硅膠與固化劑或催化劑混合后，在一定的時間內(nèi)粘度增長至膠體變成具有穩(wěn)定硬度的彈性體的這段時間叫固化時間

After the reinforced liquid silica gel is mixed with the curing agent or catalyst, the time when the viscosity increases to the time when the colloid becomes an elastomer with stable hardness is called the curing time

觸變性 Thixotropy

當(dāng)流體受到剪切力時，稠度變小，停止剪切時稠度又增加，或受到剪切時稠度變大，停止剪切時稠度又變小的性質(zhì)，即一觸及變的性質(zhì)

When the fluid is subjected to shear stress，the consistency decreases，when stops，the consistency increases.
