离型纸技术指标 Technical specifications of release paper

离型纸的技术指标有以下几个，干硅涂布量，常温剥离力，老化剥离力以及残余粘着率。

Release paper technical indicators are the following, dry silicon coating amount, normal temperature peeling force, aging peeling force and residual adhesion rate.

干硅涂布量是指：离型剂涂布在材料上的量，单位是克每平方米。一般为溶剂型硅油的涂布量从0.30~0.80克每平方米，无溶剂型硅油的涂布量从0.80~1.30克每平方米。需要专门测试设备才能测试涂布量。

The amount of dry silicon coating refers to the amount of release agent coating on the material, in grams per square meter. Generally, the coating amount of solvent-based silicone oil is from 0.30 to 0.80 grams per square meter, and the coating amount of solvent-free silicone oil is from 0.80 to 1.30 grams per square meter. Special testing equipment is required to test the amount of coating.

硅油涂布量直接影响到剥离性能。较高的涂布量，能够密实地将原纸覆盖，保证硅油均匀分布。而较低的硅油涂布量，则容易出现漏涂等现象，致使剥离不良。有些离型涂布供应商以降低硅油涂布量，致使剥离偏重，生产出重离型纸，在使用时是具有相当风险的。 可靠的生产厂家是在不降低硅油涂布量的前提下，通过化学配方的调整实现剥离力的调整。这是需要相当长时间的技术积累的，而非一蹴而就的。

The amount of silicone oil coating directly affects the stripping performance. High coating capacity, can densely cover the base paper, ensure the uniform distribution of silicone oil. The lower the amount of silicone oil coating, it is easy to appear the phenomenon of coating leakage, resulting in poor stripping. Some release coating suppliers to reduce the amount of silicone coating, resulting in heavy stripping, the production of heavy release paper, in use is quite risky. Reliable manufacturers can adjust the stripping force by adjusting the chemical formula without reducing the amount of silicone oil coating. This is a skill that takes a long time to build, not a quick fix.

常温剥离力：在常温下通过标准测试方法得到的剥离力数据，单位是N/25mm，可以转换成多少克。 一般0.10N/25mm，即10克以下的剥离力，俗称为轻剥离； 0.20N/25mm，即20克以下的剥离力，俗称为中剥离； 0.35~0.45N/25mm，即35~45克的剥离力，俗称为重剥离； 0.60~0.80N/25mm，即60~80克的剥离力，俗称为重重剥离； 当然也有0.03~0.04N/25mm，即3~4克的剥离力，俗称为轻轻剥离； 也有1.00N/25mm，即100克以上的剥离力，俗称为超重剥离。

Normal temperature stripping force: stripping force data obtained by standard test methods at normal temperature, in units of N/25mm, can be converted into grams. General 0.10N/25mm, namely 10 grams of peeling force, commonly known as light peeling; 0.20N/25mm, that is, 20 grams of peeling force, commonly known as the middle peeling; 0.35~0.45N/25mm, that is, 35~ 45g of stripping force, commonly known as heavy stripping; 0.60~0.80N/25mm, that is, 60~80 grams of stripping force, commonly known as heavy stripping; Of course, there are 0.03~0.04N/25mm, namely 3~4 grams of stripping force, commonly known as gently stripping; There is also 1.00N/25mm, that is, more than 100 grams of stripping force, commonly known as overweight stripping.

老化剥离力，经老化后测得的剥离力数据，一般较常温剥离力略大。

Aging stripping force: the stripping force measured after aging is generally slightly larger than that at normal temperature.

残余粘着率，是指离型纸在经过第一次剥离后，第二次剥离时的力，经计算后得到的数据，主要反映硅油固化的效果。 UV固化硅油的残余粘着率一般为100%，热固化硅油的残余黏着率最高为90%。少数供应商若是声称自己的离型纸残余黏着率为100%，那就可疑了。如果发生脱硅这样的情况，这种离型纸的残余粘着率一般不会高过70%。 离型纸技术指标的测试是一件相当复杂的工程。一般电子厂、胶带厂仅能测试后几项数据。至于硅油涂布量，一般不会出现于离型涂布供应商的技术报告中。

Residual adhesion rate refers to the force of the release paper after the first peeling and the second peeling. The data obtained after calculation mainly reflects the curing effect of silicone oil. The residual adhesion rate of UV curing silicone oil is generally 100%, and the highest residual adhesion rate of heat curing silicone oil is 90%. A few suppliers who claim that their release paper residual adhesion rate is 100% are suspicious. If desilication occurs, the residual adhesion rate of the release paper is generally not higher than 70%. It is a very complicated project to test the technical index of release paper. General electronic factory, tape factory can only test the last few data.The amount of silicone coating generally does not appear in the technical report of the mold coating supplier.
