【Taiwan endemic species】Bamboo sheath arrow bamboo | Bamboo leaf hairpin | Hairpin | Heat shrinkable

Sitting alone in the secluded huang, playing the piano and whistling again. People in the deep forest don't know, but the bright moon comes to shine. —— Don. Wang Wei⟪Zhuli Pavilion⟫ [Plant Knowledge] Taiwan's endemic species - Arrow bamboo ◆ Scientific name: Pseudosasa usawae ◆ Alternative names: Yazhu Aberdeen, Baoshe Yazhu ◆ Distribution: all over the lower altitude mountainous areas in central, northern and eastern Taiwan ◆ Appearance: It is a perennial evergreen herb with single leaves and alternate leaves, 1-3 or more leaves in clusters; the inflorescence is spike-shaped, and the fruit is caryopsis, but the seed setting rate is not high. ◆ Features: Arrow bamboo is named for its thin bamboo stalks that can be used to cut bows and arrows, and its shoots are called arrow shoots. In addition to being cut into bows and arrows and harpoons, they can also be used to build chicken coops, fences, make beds, furniture, etc. At the same time, arrow bamboo shoots are crispy and tender. It is a traditional delicacy of the Ami people in Hualien. It is called "laa-jih 拉志". Glutinous rice is also known as the "Three Treasures of Guangfu". 【Scientific principle】Heat shrink film Plastic is a high molecular compound, which can be divided into "thermosetting" and "thermoplastic" according to the processing properties: ◆ Thermoplastic It is chain or dendritic, and its molecules can move freely at high temperature. After heating, the components will not undergo chemical reactions, but will soften and deform. Therefore, it can be softened and melted by repeated heating, and solidified after cooling. At present, most disposable plastic food container packaging is made of thermoplastics, such as polyvinyl chloride (PVC) for making packaging films and fresh-keeping boxes. ◆ Thermosetting Plastic It has a network structure and is formed by bridging reactions. It is heated and undergoes irreversible chemical reactions such as vulcanization reactions before the finished product is manufactured. After molding, even if it is heated again, it can no longer change its shape. Only certain plastic food containers and packaging are made of thermosetting plastics. The common ones are polycarbonate used to make kettles, or polyether sulfones used to make high-temperature resistant containers such as food utensils, medical equipment, and electronic parts. And we use the heat-shrinkable sheet as a thermoplastic, it will shrink and thicken after heating, and change the heating time of the heat-shrinkable sheet by moving the heat gun, so that the petals have a shape with a thick tip and a thin edge, and heat it to soften it bending. - - - - - - - - - - 【Product Information】 ◆ Material: plastic, Bronze, hairpin (wood, bamboo, etc.) ◆ Size: 18×3×2 cm 【Customization】 The hairpin part can be freely selected: ◆ Wooden hairpin: relatively stable, can be coiled separately ◆ Bamboo hairpin: more beautiful ◆ Metal hairpin: gold and silver, can be coiled; if the hair is longer, it is recommended to choose wooden hairpin ◆ U-shaped hairpin: gold and silver, suitable for decoration after hairpin ʘ If there is no special note or the customer service is not contacted within three days after the order is placed, it will be produced according to the product photo 【Precautions】 ◆ The branches are made of paulownia wire as the skeleton, which can be bent gently ◆ The product is made to order, and the construction period is about 7-10 working days (excluding holidays). If you need it urgently, please contact us ◆ Since the products are all handmade, there may be slight differences in color and shape ◆ If dirty, please wipe gently with a thin cotton cloth ◆ Please put it in a strong box when not in use to avoid deformation of the flowers ◆ Do not get wet ◆ Reference materials: Wikipedia, including Arrow bamboo Plastic Station⟪[Plastic Knowledge] Thermoplastic and Thermosetting Plastic⟫ Plastic Industry Technology Development Center⟪Knowledge of Plastics and Proper Use——Introduction to Commonly Used Plastic Materials⟫
