There are many ways to make biobased fruit fork supplier, among which the most common one is the polymerization of ethylene under the pressure of 1000 ~ 2000 atmospheres at 200 ~ 300β. In the biobased fruit fork supplier, no other substances are doped. The produced biobased fruit fork supplier has low density, soft texture, and high stability with respect to sunlight, air, moisture and chemical agents, so there is no need to add stabilizers and plasticizers, which are mostly toxic or highly toxic.
trait
Plastic bottles are easy to carry, not afraid of falling, with acid and alkali resistance characteristics, convenient production, but also conducive to recycling.
Problem modification
(1) When planning kneading plastic bottles, it is assumed that the data is high-density biobased fruit fork supplier or polypropylene, the cross section of the plastic bottle should be rectangular or oval, and the data is low-density biobased fruit fork supplier or other flexible plastic bottles. Its cross section is better to be circular. This makes it easy to squeeze the contents out of the plastic bottle. The plastic parts used in collaboration with plastic bottle mouths are mainly bottle caps and sealers. The planning of plastic bottle mouth should consider how to make the plastic bottle mouth can better cooperate with the cap and seal. The bottom of the plastic bottle is the thin part of the mechanical function of the plastic bottle. Therefore, the bottom of the plastic bottle is generally planned into a concave shape; The corner of the plastic bottle and the inner recess are made of large arc. In order to facilitate the accumulation of plastic bottles and increase the stability of plastic bottles, the bottom of plastic bottles should be planned with grooves.
(2) When the plastic bottle surface is labeled, the labeling surface should be smooth. A "frame" can be planned on the surface of the plastic bottle, so that the label is accurately positioned and does not move. In blow molding, the part of the billet that is first touched by blowing is always the part that is first hardened. So the wall thickness there is also larger. The edge and corner parts are the parts that the billet blows and finally touches, and the wall thickness of this part is small. Therefore, the edges and corners of plastic bottles should be planned into rounded corners. Change the surface shape of the plastic bottle, such as the middle of the plastic bottle is relatively thin, increase the circumferential groove or rib on the surface of the plastic bottle, and the stiffness and bending resistance of the plastic bottle can be trekked. Longitudinal grooves or reinforcing bars can eliminate the deviation, sagging or deformation of plastic bottles under long-term load.
(3) The printing surface of the plastic bottle is the most concentrated part of the customer's efforts. The printing surface should be smooth and continuous; Assuming that the plastic bottle contains a handle, groove, reinforcement and other structures, the planning should be careful not to create inconvenience to the printing operation. Oval plastic bottle, the rigidity is also higher, but the production cost of the mold is higher. Therefore, in order to ensure the rigidity of plastic bottles, in addition to the selection of high stiffness information, but also through the shape planning of plastic bottles, enhance the rigidity and load strength of plastic bottles.
(4) Because most plastics have notch sensitivity, cracks and cracking occur briefly in the sharp corners of plastic bottles, the root of the mouth thread, the neck and other parts, so these parts should be planned into rounded corners. Regarding the transfer of rectangular plastic bottles, it is necessary to support most of the load of plastic bottles, so it is necessary to partially increase the wall thickness of the plastic bottles, and it is also conducive to the stiffness and load resistance of the plastic bottles.
