ʻIke mākou a pau he maʻalahi ka nui o ka plastic i ka hoʻokuʻu ʻana i nā carcinogens ma hope o ka hoʻomehana ʻana, e pili ana i ke olakino o ke kanaka, polypropylene, PP plastic ka mea pale wela maikaʻi loa i loko o ka plastic plastic nui ʻelima.Hoʻohana nui ʻia i ka ʻeke meaʻai.ʻO ka plastik i hoʻomehana ʻia e ka umu microwave.
ʻO ka polypropylene, i kapa ʻia ʻo PP no ka pōkole, he resin synthetic thermoplastic i hana maikaʻi ʻia me ka waihoʻoluʻu, ʻaʻala ʻole, non-toxic, translucent paʻa mea paʻa, liʻiliʻi liʻiliʻi a me ka māmā: ʻO PP ka mea ʻoi loa ka paʻa o ka plastic raw material, me ka nui o 0.89 wale nō. ~ 0.91g/cm (ʻoi aku ka liʻiliʻi ma mua o ka wai)
ʻO ke kūpaʻa wela maikaʻi: Ma nā plastics maʻamau, ʻo ka plastic plastic ka mea wela maikaʻi loa, a ʻo kona mahana deformation thermal he 80-100 ° C. Hiki ke kuke ʻia i ka wai paila.
ʻO ka paʻakikī maikaʻi: He kūpaʻa maikaʻi ʻo PP plastic i ka crackedness, a me ke ola luhi luhi kiʻekiʻe, he mea maʻalahi ke hoʻoheheʻe.
Ke kū'ē kemika: Hiki i ka plastik PP ke kū'ē i ka waikawa, ka alkali, ka wai paʻakai a me nā mea hoʻoheheʻe kūlohelohe ma lalo o 80 ° C, a hiki ke hoʻoheheʻe ʻia ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka hopena oxidation.
I ka manawa like, loaʻa i ka plastik PP ka insulation uila, nā waiwai mechanical kiʻekiʻe a me nā waiwai hoʻoili kiʻekiʻe.
ʻO nā hemahema o ka plastik PP: ka haʻahaʻa haʻahaʻa haʻahaʻa, lawa ʻole ka rigidity, ke kū ʻana o ka wā maikaʻi ʻole, a me ka "pōʻino keleawe".Loaʻa iā ia kahi hanana post-contraction.
Ma ke ʻano he ʻelima o nā plastic plastic nui, hoʻohana nui ʻia ʻo PP Plastic i ke ola o kēlā me kēia lā:
A. Ke kahua o ka ʻoihana kaʻa:PP me nā mea hoʻohui metala: pads, ventila pipes, fans, etc.
B Lako hale:
C pahu mālama hou
Ma keʻano he mea hana maʻamaunā huahana plastik a me nā poni, hiki iā ʻoe ke hālāwai i nā pono he nui ma Zhongda.Inā makemake ʻoe iā mākou, e ʻoluʻolu e kelepona mai iā mākou i kēlā me kēia manawa.
Ka manawa hoʻouna: Dec-05-2022
