Hōʻike huahana
Hōʻike huahana:
ʻO ke kaumaha o ka gram he 100g/㎡~500g/㎡;ʻO 1 ~ 6 mika ka laulā, a ʻo ka lōʻihi e like me ka makemake o ka mea kūʻai aku.
Nā hiʻohiʻona huahana:
ʻO nā waiwai kino a me nā mechanical he 2 a 3 mau manawa kiʻekiʻe ma mua o nā huahana maʻamau a he haʻahaʻa ke kaumaha kiko'ī no ke kaumaha hoʻokahi;
ʻOi aku ka maikaʻi o ka waika a me ka alkali, maikaʻi ka hoʻoheheʻe wela, a me ke kūpaʻa ikaika.
