Polypropylene Plastic(PP)
* ʻO ka polypropylene kahi thermoplastic semi crystalline. Loaʻa iā ia ke kūpaʻa hopena kiʻekiʻe, nā waiwai mechanical ikaika, a me ke kūʻē ʻana i nā mea hoʻoheheʻe organik a me ka corrosion acid-base.
* Paipai kemika maikaʻi loa nā māka palekana meaʻai.
* Nā huahana plastik PP i hoʻopilikino ʻia
ʻO ka polypropylene, i hoʻopau ʻia e like me PP, he polymer i hana ʻia mai ka propylene ma o ka hopena polymerization. He mea keʻokeʻo, waxy me ka ʻike a māmā. Kemimi kumu (C3H6)n, density 0.89 ~ 0.91g/cm3, flammable, hehee wahi o 164 ~ 170 ° C, palupalu ma 155 ° C a pela aku, ka hoʻohana 'ana i ke ana wela o -30 ~ 140 ° C.
He kūpaʻa ia i ka corrosion e ka waikawa, ka alkali, ka wai paʻakai a me nā ʻano mea hoʻoheheʻe kūlohelohe ma lalo o 80 ℃, a hiki ke decomposed ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka oxidation. Hoʻohana ʻia ia ma kahi ākea o nā noi, e komo pū me ka mea kūʻai aku i ka mea kūʻai aku, nā ʻāpana plastic no ka ʻoihana automotive a me nā textiles.
He aha kāu e hana ai me PP Plastic?
ʻO ka polypropylene ka mea maʻalahi loa ma ke ʻano o ka density. ʻO kona hiʻohiʻona he ʻano kala ʻole a translucent granules, a ma ke ʻano he plastic-grade plastic, hoʻohana nui ʻia ia i ka ʻeke meaʻai, e like me nā pahu Styrofoam, nā kīʻaha plastik PP, a pēlā aku. Hiki ke hoʻokaʻawale ʻia ka Polypropylene i ʻelima mau ʻāpana nui e like me kāna mau noi nui: PP injection molding, PP drawing, PP fiber, PP film, a me PP pipe.
Eia kekahi mau noi no ka Polypropylene (pp)
- Nā mea lapaʻau
- ʻāpana kaʻa
- ʻO nā pahu meaʻai
- Hoʻopili ʻia
- Mea lako kīʻaha
- Nā ʻōmole
- Nā lole
- mea pāʻani
- ʻO nā pāpale ʻōmole
- Nā lole lole
- Nā huahana i ulana ʻia
- Nā mea hana hale
- Nā huahana mea kūʻai aku
- Nā lako kīhāpai
- Nā lako hale liʻiliʻi
Polypropylene (PP) ʻano
Ke kū'ē i ke kemika: ʻAʻole i hoʻopili ʻia nā kumu hoʻoheheʻe a me nā ʻakika me ka PP, no laila he ipu kūpono ia no ia mau wai (e laʻa me nā mea hoʻomaʻemaʻe, nā huahana kōkua mua, etc.).
ʻO ka elasticity a me ka paʻakikī: Elastic ka PP i loko o kekahi ʻano o ka deflection a hoʻololi i ka plastic deformation i ka hoʻomaka ʻana o ke kaʻina deformation me ka ʻole o ka haki ʻana, no laila ua manaʻo ʻia he mea "paʻakikī".
Ka pale ʻana i ka luhi: Mālama ʻo PP i kona ʻano ma hope o ka wili a me ke kulou ʻana. He waiwai nui kēia waiwai no ka hana ʻana i nā hinges hiki ke hoʻoneʻe.
Insulation: He kiʻekiʻe ka pale uila o ka mea PP a he mea insulating.
Transmittance: Hiki ke hana ʻia i nā kala ʻālohilohi, akā hana maʻamau i nā kala opaque kūlohelohe me kahi pae o ka transmittance. Inā makemake ʻia ka transmittance kiʻekiʻe, pono ke koho ʻia ka acrylic a i ʻole PC.
Pehea i hana ʻia ai ka mea PP?
E like me nā plastics ʻē aʻe, hoʻomaka ka Polypropylene (PP) ma ke ʻano he "hapa" (hui māmā) mai ka distillation o nā wahie hydrocarbon a hui pū me nā catalysts e hana i nā plastics ma o ka polymerization a i ʻole polycondensation reactions.

Polypropylene (PP)- Kaʻina hana:
Lawe ʻia ka pauka i loaʻa i ka pauka silos a laila hoʻololi ʻia i pellets e hoʻokomo i kahi ʻano piha
nā mea hoʻohui maikaʻi.
ʻO ka polypropylene (PP) ka hana hou ʻana a me ka pale ʻana i ke kaiapuni
Ke hana hou ʻia ka polypropylene, hoʻemi ia i ka hoʻohana ʻana i nā kumuwaiwai palena ʻole e like me ka aila a me ke kinoea propane. Ma kahi o 8% o ka aila o ka honua (e pili ana i 400 miliona tons) i hoʻohana ʻia i nā hana hana plastics kuʻuna, kahi o 4% i hoʻohana ʻia ma ke ʻano he "feedstock" a hoʻohana ʻia kekahi 4% i ka hana ʻana. Inā hana ʻia nā plastics mai nā plastic recycled, e hoʻemi ʻia ka hoʻohana ʻana i ka ikehu e 88%. ʻO ka hana hou ʻana i nā plastic polypropylene no laila he mea aloha kaiapuni!
E hoʻomaka i kāu papahana SendCutSend mua i kēia lā!
Hoʻouka i kāu hoʻolālā CAD a hoʻohana paha i kā mākou mea hana ʻāpana a loaʻa i kahi ʻōlelo kūʻai manuahi ma kāu mau ʻāpana ʻoki laser maʻamau, hāʻawi ʻia i kou puka i loko o nā lā.
E hoʻopaʻa i kahi kaʻa i kēia manawa
