He aha nā mea i hoʻohana mau ʻia ʻekolu

Pono e ʻōlelo ʻekolu, pono: PPR, PVC, PE

1. ʻO nā paipu plastik maʻamau: PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (polyethylene pale wela), PE (polyethylene) \HDPE (reinforced high-density polyethylene) ethylene), etc.

ʻO ka lua, ua hōʻike ʻia ka nui o nā paipu plastik ma ke ʻano o ke anawaena o waho.E like me PPR paipu: De63

3. Ke ola lawelawe oMF BALL VALVE X9011ua hoʻoholo ʻia e like me GB / T18252-2000 "Plastic pipe system - Ka hoʻoholo ʻana i ka ikaika hydrostatic lōʻihi o nā paipu thermoplastic e ka extrapolation".ʻO kēia ke ʻano o ka extrapolating a me ka wānana i nā waiwai ikaika lōʻihi o nā mea thermoplastic a i ʻole nā ​​​​ʻatikala mai nā hopena o nā hoʻokolohua ikaika hydrostatic o nā paipu.* Hoʻohana ka hapa nui o nā mea i luna i kēia ʻano e helu ai, ma lalo o ke kūlana wela o 20 ℃, he 50 mau makahiki ke ola o ka paipu plastik.

ʻO ka hā, ʻo nā mea hana hoʻoheheʻe no nā paipu plastik he mīkini hoʻoheheʻe ʻia, i hoʻoheheʻe ʻia i loko o nā paipu e ka mīkini hoʻoheheʻe ʻia.

5. ʻElua mau ala e hoʻopili ai i nā paipu plastik: hoʻoheheʻe wela a me ke kāpili.

6. ʻO nā maʻamau no nā paipu plastik ka mea nui:

1. PPR (polypropylene): GB/T18742.1, GB/T18742.2, GB/T18742.3

2. PVC (polyvinyl chloride): GB / T10002.1-2006, GB / T10002.2-2003

3. PE (polyethylene): GB15558, GB/T13663

4. HDPE (Enhanced High Density Polyethylene): GB/T19472.2-2004

ʻO nā paipu plastik ka nui o ka PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (heat-resistant polyethylene), PE (polyethylene), HDPE (enhanced high-density polyethylene), etc. ʻO nā mea i hoʻohana ʻia. polypropylene (PP), polyvinyl chloride (PVC), polyethylene (PE) a me nā polymers ʻē aʻe.

He huaʻōlelo maʻamau no nā paipu i hana ʻia me nā mea plastik.Loaʻa i nā paipu plastik nā hiʻohiʻona o ke kaumaha māmā, ka hoʻomaʻemaʻe a me ka palekana, ke kahe wai liʻiliʻi, ka mālama ʻana i ka ikehu, ka mālama metala, ka hoʻomaikaʻi ʻana i ka nohona, ke ola lōʻihi, ka palekana a me ka ʻoluʻolu, a me nā mea ʻē aʻe, a ua makemake ʻia e ka hui ʻenehana pipeline.I nā makahiki he 10 i hala iho nei, i alakaʻi ʻia e ka hoʻomohala macroeconomic o koʻu ʻāina, ua ʻike nā paipu plastik o koʻu ʻāina i ka ulu wikiwiki ʻana ma lalo o ke ʻano o ka hoʻomohala nui ʻana o nā mea hale kemika.I ka makahiki 2010, ua ʻoi aku ka nui o nā paipu plastik ma mua o 8 miliona mau tona, a ʻo Guangdong, Zhejiang a me Shandong i helu ʻia no 42% o ka hopena.He nui nā mea maikaʻi o nā paipu palaki ma mua o nā paipu metala kuʻuna a me nā paipu paʻa ma nā kahua he nui, no laila ua hoʻohana nui ʻia lākou ma nā wahi he nui.
