欧宝体育登陆首页怎样区别好不好?
欧宝体育登陆首页怎样区别好不好?
1、浸泡法。分别将两种欧宝体育登陆首页浸泡入两个装有清水的碗中,欧宝体育登陆首页立刻就被浸透,用手指轻轻一碰就烂了,如果纸直接成了“烂泥”就是不好的欧宝体育登陆首页。合格的欧宝体育登陆首页则缓慢地浸透,用手搅拌也不会烂掉,用手捞起来以后依然是完整的。
1. Soaking method. Soak the two kinds of toilet paper in two bowls with clear water, and the toilet paper will be soaked immediately. It will rot with a gentle touch of your finger. If the paper becomes "mud" directly, it will be a bad toilet paper. Qualified toilet paper is slowly soaked, stirring by hand will not rot, and it is still intact after being picked up by hand.
2、撕扯法。轻轻一拉就撕烂了,而且裂口很毛,不够整齐,桌面上也掉落一层白灰,就是不合格的欧宝体育登陆首页。合格欧宝体育登陆首页韧性较强,拉扯完放开,纸面上有拉扯的纹路,撕开以后,裂口很整齐,桌面也不见白灰。
2. Tearing method. A slight pull will tear, and the cracks are very furry, not neat enough, the desktop also dropped a layer of white ash, that is, unqualified toilet paper. Qualified toilet paper has strong toughness. When it is pulled and released, there are stretched lines on the paper surface. After tearing, the cracks are very neat, and the desktop is not white ash.
撕的时候还有一个诀窍,如果是纯木浆制作的欧宝体育登陆首页,当你横着撕一次,再竖着撕一次,对比前后的撕裂口会发现不一样,差别明显;而差的欧宝体育登陆首页,横着竖着撕的裂口都是一样的。
There is also a trick when tearing, if it is made of pure wood pulp toilet paper, when you tear it horizontally and vertically again, the tear opening before and after comparison will be different, the difference is obvious; and poor toilet paper, the tear opening is the same horizontally and vertically.
3、燃烧法。燃烧欧宝体育登陆首页。点燃后,合格纸巾燃烧时依然比较完整,但不合格纸巾不时有灰飞起,烧完以后,合格纸巾的颜色偏黑,如木炭燃烧完的颜色,且纸灰是一张完整的网状,但散装餐巾纸却呈灰白色,比较零散地堆在一起,没有通透的网状感觉。
3. Combustion method. Burn toilet paper. After ignition, the qualified napkins are still relatively complete when burning, but the unqualified napkins fly up from time to time. After burning, the color of qualified napkins is black, such as charcoal burned out, and the ash is a complete net, but the bulk napkins are gray-white, scattered together, without a transparent network feeling
