紙豆腐為什麼不能包覆空氣?



在手工造紙要使用竹簾,竹簾的特性是可以折成90度,當師傅在決定紙張厚度之後,會將含水量很多的紙放置於置紙板上,當他第一張置紙時,在置紙板上舖了一張塑膠網或布或草蓆等,這些覆蓋物須淋上水,此時濕紙上上去時能利用毛細作用,讓水份子的結合將竹簾上的紙吸附於覆蓋物上,那麼第二張完成的紙就吸附於第一張紙上,如此一直重覆置紙,形成所謂的紙豆腐。


在重覆置紙過程,竹簾須折成90度的角度,是因為紙豆腐的表面如有異物或空氣形成較高的點,紙張放上去時較高的點會讓紙豆腐的紙與竹簾上的紙槳接觸,那麼高點周圍的紙會無法接觸,而無法毛細現象,順利的讓竹簾上的紙吸附於紙豆腐上,而竹簾掀起它還附著於竹簾上,這一張紙就破掉了,所以竹簾置紙時要折成90度是為防止紙面有空氣泡產生,師傅在抄紙時,如紙面上有雜質,需用鑷子夾起,夾起的地方有破洞要修補,如此紙面同高,氣泡就不會產生,如在置紙時在紙豆腐表面形成氣泡,需用很細的吸管,用嘴巴將氣泡內的空氣吸出來,這樣才不會影響下一張紙的操作。

紙張放久愈好用?

紙張中的纖維接受空氣中的溫度、濕度,會熱漲冷縮,放置長時間的紙,纖維會因這原理而彈性疲乏,此時會產生所謂“潤”的感覺,這種紙在使用時,纖維收縮膨脹會比較不明顯,所以存紙如存酒、存茶一樣愈久愈有味! 通常剛烘乾仍有熱度的紙,假設一百張是3000公克,等放置冷卻之後會變成3100公克,多出來的100公克就是水份,紙張既然愈放愈好用,就用塑膠袋存封放置,既可防潮又可防蟲,但此舉卻犯存紙之大忌,裝在塑膠袋

Consider a scenario in which WWA and our collaborators could assume the preponderance, if not the entirety, of this monitoring phrazle and assessment work. Consider the capacity expansion that would benefit our financially constrained National Forest partners.
