Nneɛma a wɔde yɛ PET plastic nneɛma ne sɛnea wɔde di dwuma .

PET yɛ Engiresi kasa mu polyethylene terephthalate a wɔatwa no tiaa. Ɛkyerɛ polyethylene terephthalate plastic, a polyethylene terephthalate PET ne polybutylene terephthalate PBT ka ho titiriw. Wɔtaa frɛ polyethylene terephthalate nso sɛ polyester resin.

PET plastic nhyehyɛe .

Molecule nhyehyɛe a ɛwɔ PET plastic mu no yɛ symmetrical kɛse na ɛwɔ crystal orientation tumi pɔtee bi, enti ɛwɔ film-forming ne forming properties a ɛkorɔn. PET plastic wɔ optical ahoɔden pa ne wim tebea a ɛko tia, na amorphous PET plastic wɔ optical transparency pa.

Bio nso, PET plastic wɔ abrasion resistance a ɛkyɛn so, dimensional stability, ne electrical insulation. Nkotoku a wɔde PET ayɛ no wɔ ahoɔden a ɛkorɔn, ɛda adi yiye, ɛnyɛ awuduru, ɛko tia, emu yɛ hare na ɛyɛ adwuma yiye, enti wɔde adi dwuma kɛse. PBT no molecule nkɔnsɔnkɔnsɔn nhyehyɛe no te sɛ PET de no, na ne su dodow no ara yɛ pɛ, gye sɛ molecule no nkɔnsɔnkɔnsɔn titiriw no asesa afi methylene akuw abien so akɔ anan so, enti molecule no yɛ nea ɛyɛ mmerɛw kɛse na adwumayɛ no adwumayɛ ye.

Pet Features .

PET yɛ polymer a ɛyɛ fitaa a ɛyɛ nufusu anaa kɔkɔɔ a ɛyɛ hann a ɛyɛ ahwehwɛ a ɛyɛ fɛ a ɛwɔ soro a ɛyɛ mmerɛw na ɛhyerɛn. PET wɔ nneɛma a edidi so yi:

1. Ɛwɔ creep resistance pa, ɔbrɛ resistance, friction resistance ne dimensional stability, low wear ne high hardness, na ɛwɔ toughness a ɛsen biara wɔ thermoplastics mu.

2. Electrical insulation adwumayɛ pa, ɔhyew ketewaa bi nkɛntɛnso, nanso corona resistance a enye.

3. Non-toxic, wim tebea a ɛko tia, nnuru a ɛko tia, nsu a ɛba fam a ɛtwetwe, a ɛko tia acid a ɛyɛ mmerɛw ne organic solvents, nanso ɛnyɛ nea ɛko tia nsu a ɛyɛ hyew a wɔde gu mu ne alkali.

4. Glass transition temperature a ɛwɔ PET resin mu no yɛ kɛse, crystallization ahoɔhare no yɛ brɛoo, molding cycle no tenten, molding cycle no tenten, molding shrinkage rate no yɛ kɛse, dimensional stability no nyɛ papa, crystallization molding no yɛ brittle, na ɔhyew a ɛko tia no sua.

Lamination PET su ahorow .

Ɛdenam nucleating agent, crystallizing agent, ne glass fiber reinforcement a ɛma ɛkɔ anim so no, PET wɔ su ahorow a edidi so yi a ɛka PBT no su ho:

1. Ɔhyew a ɛkyinkyim no hyew ne ɔhyew a wɔde di dwuma bere tenten no yɛ nea ɛkorɔn sen biara wɔ thermoplastic general engineering plastics mu.

2. Esiane sɛ ne ho yɛ hyew kɛse nti, wɔde PET a wɔahyɛ no den no hyɛ solder bath mu wɔ 250°C ma 10s a enni deformation anaasɛ ne kɔla nsakra, a ɛfata titiriw ma ɛlɛtrɔnik ne anyinam ahoɔden afã horow a wɔde solder ayɛ no.

3. Bending ahoɔden yɛ 200MPa, elastic modulus yɛ 4000MPa, creep resistance ne ɔbrɛ resistance nso ye paa, soro denden no yɛ kɛse, na mfiridwuma su no te sɛ nea ɛwɔ thermosetting plastics mu no.

4.Esiane sɛ ɛkame ayɛ sɛ ethylene glycol a wɔde yɛ PET no bo yɛ den sen Butanediol de a wɔde di dwuma wɔ PBT, PET resin ne PET a wɔahyɛ no den mu no yɛ bo a ɛba fam sen biara wɔ mfiridwuma mu plastic mu na ɛwɔ adwumayɛ a ɛho ka yɛ den.
