3. Pɔlivinil Kloraid (PVC)

PVC ji nɔ ko ni jara waaa ni ekɛ nitsumɔ waaa plastic ni haa hulu tsoɔ ni afɔɔ nitsumɔ yɛ tsumaa nibii, tsofafeemɔ he nibii, kɛ nibii ni akɛwoɔ mli lɛ amli. Sɛɛnamɔi titrii ni yɔɔ he lɛ ekomɛi ji:

• Plasticity ni nɔ kwɔ: PVC lɛ he nitsumɔ waaa, ni abaanyɛ akɛ nibii srɔtoi afata he koni ekɛtsake bɔ ni eyɔɔ ha lɛ.

Shi, nɔ ni ehiii yɛ PVC he ji bɔ ni etsuuu nii jogbaŋŋ yɛ shihilɛ mli, ejaakɛ ebaanyɛ ejie nibii ni yeɔ mɔ awui yɛ be mli ni atsuɔ he nii kɛ be mli ni ashɛrɛɔ ashwieɔ lɛ, ni no haa ehe hiaa ni akɛtsu nii jogbaŋŋ yɛ nitsumɔi ni shihilɛ mli taomɔ nii babaoo yɔɔ mli lɛ amli.

4. Polistain (PS)

PS ji plastic ko ni mli tse waa ni ejara waaa ni akɛtsuɔ nii babaoo yɛ niyenii ni akɛwoɔ tsɔne mli, nibii ni akɛyeɔ nii, kɛ tsɔnei ni akɛtsuɔ nii yɛ tsɔne mli lɛ amli. Sɛɛnamɔi titrii ni yɔɔ he lɛ ekomɛi ji:

• Nɔ ni haa mɔ naa kpɛɔ ehe waa: PS lɛ yɛ nɔ ni haa mɔ naa kpɛɔ ehe jogbaŋŋ, ni ehaa ajieɔ nibii ni akɛtsuɔ nii lɛ akpo faŋŋ.
• Eyɛ mlɛo akɛ aaatsu he nii: Eyɛ mlɛo akɛ aaafee PS lɛ thermoform, ni abaanyɛ afee lɛ oya ni efee nibii ni yɔɔ hwanyaŋŋ.
• Shika ni baa shi: PS lɛ shika ni akɛfeɔ lɛ faaa, ni no hewɔ lɛ ehi kɛha nibii babaoo ni afeɔ lɛ.

Nɔ ni ehiii yɛ PS he ji bɔ ni ehiɛɛɛ shi jogbaŋŋ lɛ, ni no haa efoɔ oya, ni ehiii kwraa kɛha nitsumɔi ni biɔ hewalɛ ni nɔ kwɔ.

5. Polilaktik Asid (PLA)

PLA ji plastic ko ni nyɛɔ efiteɔ ni etsuɔ ​​nii jogbaŋŋ yɛ shihilɛ mli, ni akɛtsuɔ nii babaoo yɛ niyenii ni akɛwoɔ tsɔne mli, tsofafeemɔ nibii, kɛ 3D kalamɔ mli. Sɛɛnamɔi titrii ni yɔɔ he lɛ ekomɛi ji:

• Shihilɛ mli nitsumɔ kpakpa: PLA lɛ nyɛɔ efiteɔ kwraa ni ekɛ shihilɛ mli taomɔ nii lɛ kpãa gbee.
• Nɔ ni haa mɔ tsui nyɔɔ emli: PLA lɛ yɛ nɔ ni haa mɔ tsui nyɔɔ emli jogbaŋŋ, ni ehaa ajieɔ nibii ni akɛtsuɔ nii lɛ akpo yɛ faŋŋ mli.
• Nibii ni akɛtsuɔ nii ekoŋŋ: Abaanyɛ akɛ PLA atsu nii ekoŋŋ ni akɛtsu nii ekoŋŋ, ni no baaha nibii ni akɛtsuɔ nii lɛ afitemɔ aba shi.

Nɔ ni ehiii yɛ PLA he ji bɔ ni enyɛɛɛ ekɛ dɔlɛ atsu nii jogbaŋŋ, ejaakɛ kɛ́ edɔ waa lɛ, efɔɔ fitemɔ, ni no haa ehe hiaa ni akɛtsu nii yɛ hiɛdɔɔ mli yɛ hei ni edɔɔ waa lɛ.
