Polypropylene (PP) He thermoplastic i hana ʻia mai ka polymerisation o ka propylene, me ka insulation uila maikaʻi, ke kūpaʻa kemika, ke kūpaʻa wela (ʻoiai ʻaʻole maikaʻi e like me kekahi mau plastics wela kiʻekiʻe), ka ikaika tensile a me ke kūpaʻa hopena.
Wahi a ka mana hou loa o nā kūlana honua ISO 15874-2-2013
Hiki ke hoʻokaʻawale ʻia nā paipu wai wela a me ke anu o ka polypropylene i ʻehā mau PP-H nui, PP-B, PP-R a me PP-RCT, a hiki ke ʻike ʻia kēia kauoha ma ke ʻano he kauoha iterative o ka huahana, ʻoi aku ka ikaika o ka hana piha, akā loaʻa i kēlā me kēia ko lākou mau ikaika ponoʻī, eia ka mea e hoʻolauna ʻia:
ʻO ka mea mua, ka paipu plastik PP-H laina extrusion paipu (i ʻike nui ʻia ʻo ka polypropylene ʻano I)
Introduction: ʻO ka paipu PPH (Polyproplyene-Homo homopolymer polypropylene pipe), i ʻike nui ʻia ʻo Type I polypropylene, ʻo ia ka mea PP maʻamau no ka hoʻololi beta, no laila he ʻano like a palupalu hoʻi ke ʻano kristal Beta.
helehelena: ʻO ke kūpaʻa kemika maikaʻi loa, ke kūpaʻa i ka abrasion, ka insulation maikaʻi, ke kūpaʻa wela kiʻekiʻe, hiki i ka mahana hana ke piʻi i 100 ℃, ʻaʻohe mea ʻawahia, kaumaha māmā, he nui ka maikaʻi o kēia huahana ma mua o ke kūpaʻa wela kiʻekiʻe o ka paipu PP, ke kūpaʻa i ka corrosion, a me ka anti-aging.
hoʻohana: He kūpaʻa maikaʻi loa nā mea paipu PPH i ka wela a me ke kūpaʻa i ka pala, no laila hoʻohana pinepine ʻia lākou i nā ʻōnaehana halihali wai wela kiʻekiʻe, e like me ka lako wai wela, nā ʻōnaehana hoʻomehana, a me nā ʻōnaehana paipu ʻoihana kemika corrosive.
ʻO ka lua, ka paipu PP-B (i ʻike nui ʻia ʻo ka polypropylene ʻano II)
Introduction: Hana ʻia ka paipu PP-B i ka polypropylene copolymer poloka, i ʻike nui ʻia ʻo Type II polypropylene, loaʻa iā PP-B kahi ʻike kiʻekiʻe o ka ethylene copolymer, e hāʻawi ana i ka paipu PP-B i ke kūpaʻa hopena haʻahaʻa kiʻekiʻe, i hiki ai iā ia ke mālama i ka paʻakikī o ke kaiapuni haʻahaʻa, ʻaʻole maʻalahi e haki a lilo paha i mea palupalu.
helehelena: ʻO ka maʻamau, nalowale kekahi o nā waiwai wela kiʻekiʻe o PP-B i hoʻohālikelike ʻia me nā ʻano polypropylene ʻē aʻe. ʻO kēia no ka mea ʻo ke alo o nā ethylene copolymers e hoʻohaʻahaʻa i ka pae heheʻe o PP-B, no laila ʻaʻole ia e ʻae i nā mahana kiʻekiʻe e like me PP-H.
E hoʻohana i: Hoʻohana pinepine ʻia ka paipu PP-B i nā ʻōnaehana paipu no ka hoʻolako ʻana i ka wai anuanu a me ka wai mahana maʻamau, e like me nā ʻōnaehana hoʻolako wai piula no ke kūkulu ʻana, nā hale noho a me nā ʻoihana. Hoʻohana ʻia nō hoʻi ia i ka ʻoihana kemika no nā ʻōnaehana paipu i hoʻohana ʻia e halihali i nā ʻano kemika ʻaʻole e palaho, nā waikawa, nā alkalis a me nā mea hoʻoheheʻe.
'Ōlelo Aʻo: ʻAʻole kūpono ʻo PP-B no nā noi e pono ai ka lawelawe ʻana i ka wai wela kiʻekiʻe a i ʻole nā kemika, no ka mea, hiki ke palupalu a nalowale paha kona mau waiwai mechanical i nā mahana kiʻekiʻe.
ʻO ke kolu, ka paipu PP-R (i ʻike nui ʻia ʻo Type III polypropylene)
Introduction:ʻO ka paipu PP-R (polypropylene random), i ʻike ʻia hoʻi ʻo ka paipu polypropylene tripropylene, ka paipu polypropylene copolymer random, he ʻano paipu e hoʻohana ana i ka polypropylene copolymer random ma ke ʻano he mea maka.
helehelena: ʻO ka maʻamau, nalowale kekahi o nā waiwai wela kiʻekiʻe o PP-B i hoʻohālikelike ʻia me nā ʻano polypropylene ʻē aʻe. ʻO kēia no ka mea ʻo ke alo o nā ethylene copolymers e hoʻohaʻahaʻa i ka pae heheʻe o PP-B, no laila ʻaʻole ia e ʻae i nā mahana kiʻekiʻe e like me PP-H.
E hoʻohana i: Hoʻohana pinepine ʻia ka paipu PP-B i nā ʻōnaehana paipu no ka hoʻolako ʻana i ka wai anuanu a me ka wai mahana maʻamau, e like me nā ʻōnaehana hoʻolako wai piula no ke kūkulu ʻana, nā hale noho a me nā ʻoihana. Hoʻohana ʻia nō hoʻi ia i ka ʻoihana kemika no nā ʻōnaehana paipu i hoʻohana ʻia e halihali i nā ʻano kemika ʻaʻole e palaho, nā waikawa, nā alkalis a me nā mea hoʻoheheʻe.
'Ōlelo Aʻo: ʻAʻole kūpono ka PP-B no nā noi e pono ai ka lawelawe ʻana i ka wai wela kiʻekiʻe a i ʻole nā kemika, no ka mea hiki ke palupalu a nalowale paha kona mau waiwai mechanical i nā mahana kiʻekiʻe.
ʻO ke kolu, ka paipu PP-R (i ʻike nui ʻia ʻo Type III polypropylene)
Introduction: ʻO ka paipu PP-R (polypropylene random), i ʻike ʻia hoʻi ʻo ka paipu polypropylene tripropylene, ka paipu polypropylene copolymer random, he ʻano paipu e hoʻohana ana i ka polypropylene copolymer random ma ke ʻano he mea maka.
helehelena: Hoʻopau ia i nā waiwai pono o PP-H a me PP-B, hiki ke kū i kekahi mau mahana kiʻekiʻe a hoʻomaikaʻi i ke kūpaʻa ʻana i ka hopena haʻahaʻa, a me ka loaʻa ʻana o ke kūpaʻa kolo maikaʻi aʻe, e lilo ia i mea makemake nui ʻia, hiki ke hoʻohana nui ʻia i nā ʻōnaehana wai wela a me ke anu.
E hoʻohana i: ʻŌnaehana wai anuanu a me wela o nā hale, nā ʻōnaehana hoʻomehana, a me nā ʻōnaehana hoʻolako wai maʻemaʻe.
