| 1、极性化学键与模具表面通过相互作用形成具有再生力的吸附型薄膜； 1. The polar chemical bond interacts with the surface of the die to form a regenerative adsorptive film. 2、聚硅氧烷中的硅氧键可视为弱偶极子（Si+-O-),当脱模剂在模具表面铺展成单取向排列时，分子采取特有的伸展链构型； 2. Silicon-oxygen bonds in polysiloxane can be regarded as weak dipoles (Si +-O-). When the release agent is spread on the surface of the die in a single orientation arrangement, the molecule adopts a unique stretching chain configuration. 3、自由表面被烷基以密集堆积方式覆盖，脱模能力随烷基密度而递增；但当烷基占有较大空间位阻时，伸展构型受到限制，脱模能力又会降低； 3. The free surface is covered by alkyl in a dense stacking manner, and the demoulding ability increases geshanb.89ix.comtaiyangn.89ix.comgelidun.89ix.comgangguanp.89ix.comtongshizi.71ix.comzhuzaojm.3 7ix.com.cnwith the alkyl density. However, when alkyl occupies a larger space steric resistance, the extension configuration is limited and the demoulding ability decreases. 4、脱模剂分子量大小和粘度也与脱模能力相关，分子量小时，铺展性好，但耐热能力差。4. Molecular weight and viscosity of demoulding agent are also related to demoulding ability. Molecular weight is small, spreading is good, but heat resistance is poor. |
