5996 kāʻei conveyor kāʻei hoʻoheheʻe ʻulaʻula modular

Nā waiwai kino:

ʻO ka polypropylene he mea ʻawaʻawa ʻole, ʻaʻala ʻole, ʻono ʻole ka waiū keʻokeʻo keʻokeʻo keʻokeʻo polymer kiʻekiʻe, ʻo 0.90~.091g/cm3 wale nō ka nui, ʻo ia kekahi o nā ʻano māmā loa o nā plastics āpau i kēia manawa.

ʻOi aku ka paʻa i ka wai, i ka wai 24h wai absorption rate he 0.01% wale nō, ʻo ka molecular volume e pili ana i 8-150,000, hoʻoheheʻe maikaʻi ʻia, akā no ka emi ʻana, nā huahana pā mānoanoa e maʻalahi i ka sag, maikaʻi ka ʻili o ka huahana, maʻalahi ke kala.

He maikaʻi ka pale wela o PP, he 164-170 ℃ ka helu hoʻoheheʻe, hiki ke sterilized a sterilized nā huahana i nā mahana ma luna o 100 ℃, inā ʻaʻohe ikaika o waho 150 ℃ ʻaʻohe deformed, ʻo ka embrittering mahana he -35 ℃, ma lalo -35 E hiki mai ana ka embrittering, ʻaʻole maikaʻi ka pale anuanu e like me ka polyethylene.

Paʻa Kemika:

He kūpaʻa kemika maikaʻi ka Polypropylene, ʻAʻole maʻalahi wale ka sulfuric acid, nitric acid erosion, akā paʻa nō hoʻi no nā ʻano reagents ʻē aʻe, akā ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa momona hydrocarbon, aromatic hydrocarbon a me chlorinated hydrocarbon hiki ke hana i ka palupalu a me ka pehu ʻana o PP, pēlā. e like me kona kūpaʻa kemika i ka manawa like aia kekahi piʻi me ka piʻi ʻana o ka crystallinity, suitfor chemical pipe a me nā mea hana pono, no laila maikaʻi ka hopena anti-corrosion polypropylene.

ʻoi aku ka maikaʻi o ka hana insulation kiʻekiʻe, ʻaneʻane ʻaʻohe wai e hoʻopili ʻia, ʻaʻole pili ka hana insulation e ka haʻahaʻa
