衛生紙怎樣區別好不好?

1、浸泡法。分別將兩種衛生紙浸泡入兩個裝有清水的碗中,衛生紙立刻就被浸透,用手指輕輕一碰就爛了,如果紙直接成了“爛泥”就是不好的衛生紙。合格的衛生紙則緩慢地浸透,用手攪拌也不會爛掉,用手撈起來以后依然是完整的。
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。輕輕一拉就撕爛了,而且裂口很毛,不夠整齊,桌面上也掉落一層白灰,就是不合格的衛生紙。合格衛生紙韌性較強,拉扯完放開,紙面上有拉扯的紋路,撕開以后,裂口很整齊,桌面也不見白灰。
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.
撕的時候還有一個訣竅,如果是純木漿制作的衛生紙,當你橫著撕一次,再豎著撕一次,對比前后的撕裂口會發現不一樣,差別明顯;而差的衛生紙,橫著豎著撕的裂口都是一樣的。
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、燃燒法。燃燒衛生紙。點燃后,合格紙巾燃燒時依然比較完整,但不合格紙巾不時有灰飛起,燒完以后,合格紙巾的顏色偏黑,如木炭燃燒完的顏色,且紙灰是一張完整的網狀,但散裝餐巾紙卻呈灰白色,比較零散地堆在一起,沒有通透的網狀感覺。
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
