After the release of the iPhone 12, many discussions have been raised, with topics such as color, price, configuration, and whether it is worth buying
.
However, the majority of netizens did not buy it, and complained one after another: it means that Apple is not going to want new users, and is ready to pay for the old money; there are at home, but the charging cable and headphone cable are about to break, okay? Apple is too confident in its quality Come on; Apple's sockets are not the same as Android's, which is the source of material waste.
.
.
The editor, who is not an Apple user, can't help but want to complain.
Probably only Apple dares to do such a thing and give such a "reasonable explanation"
.
Whether it is a mobile phone charger or a headset, the shell is generally made of ABS or PC material
.
PC has high strength and elastic coefficient, high impact strength, wide temperature range, high transparency and free dyeing, high HDT, good fatigue resistance, good weather resistance, excellent electrical properties, low molding shrinkage, good dimensional stability, etc.
Features, commonly used in electronic appliances, such as CDs, switches, home appliance shells, signal tubes, telephones,
etc.
Compared with these two materials, ABS is not resistant to high temperature, and the long-term use temperature should not be higher than 60 °C, while the thermal deformation temperature of PC is 135 °C
.
The outer covering material of the data cable includes PVC, TPE, and braided wire.
The characteristics of each are:
PVC material is a commonly used material for most data cables.
It has non-flammability, high strength, weather resistance and excellent geometric stability
.
TPE material is actually a soft rubber material that can be processed by ordinary thermoplastic molding machines.
Its elasticity and toughness have been greatly improved compared with PVC materials.
However, the most important thing is that it is more environmentally friendly and can be Recycling reduces costs
.
Most of the data cables made of braided wires are made of nylon.
As we all know, nylon is a kind of clothing material, so the folding resistance and durability of data cables made of braided wires are naturally higher than those of PVC and TPE materials.
But unfortunately, it has not been adopted by mobile phone manufacturers
.
The topic of reducing carbon emissions has been raised countless times, and plastic has also been blamed countless times, but in fact plastic is only a very small role
.
Compared with the convenience that plastic brings to human life, it is simply insignificant
.
To protect the environment and save resources, it is far from enough to reduce the use.
What is more important is how to recycle and reuse materials, and maximize the value of resources through recycling
