He aha nā waiwai pono e loaʻa i nā mea waihoʻoluʻu plastic?

ʻO ka Hue, ka māmā, a me ka saturation nā mea ʻekolu o ke kala, akā ʻaʻole lawa ke kohomea waihoʻoluʻu plastics pili wale i nā mea ʻekolu o ke kala.ʻO ka mea maʻamau e like me ka mea ʻulaʻula, ʻo kona ikaika tinting, ka mana huna, ka pale ʻana i ka wela, ka neʻe ʻana o ka neʻe ʻana, ka pale ʻana i ka wā, ka pale ʻana i ka solvent a me nā waiwai ʻē aʻe e pono e noʻonoʻo ʻia, a me ka launa pū ʻana o nā kala me nā polymers a i ʻole nā ​​​​mea hoʻohui.
(1) Hiki ke kala kala
ʻO ka ikaika kala kala e pili ana i ka nui o ka puaʻa i koi ʻia no ka loaʻa ʻana o kekahi huahana kala, i hōʻike ʻia ma ke ʻano he pākēneka o ka ikaika kala o kahi laʻana maʻamau, a pili i nā waiwai o ka puaʻa a me kona hoʻopuehu.Ke koho ʻana i kahi kala, pono ʻia e koho i kahi kala me ka ikaika o ke kala e hōʻemi i ka nui o ka kala.

(2) Ka mana uhi ikaika.
ʻO ka mana huna ikaika e pili ana i ka hiki o ka puaʻa ke uhi i ke kala hope o ka mea ke hoʻopili ʻia i ka ʻili o ka mea.Hiki ke hōʻike ʻia ka mana huna ma ka helu a ua like ia me ka nuipaʻa o ka puaʻa (g) i koi ʻia no kēlā me kēia ʻāpana ʻili ke uhi ʻia ke kala hope.ʻO ka maʻamau, ʻo nā puaʻa inorganic he mana uhi ikaika, ʻoiai ʻo nā puaʻa organik he aniani a ʻaʻohe mana uhi, akā hiki iā lākou ke loaʻa ka mana uhi ke hoʻohana pū ʻia me ka titanium dioxide.

(3) Kūleʻa wela maikaʻi.
ʻO ke kūpaʻa wela o nā puaʻa e pili ana i ka hoʻololi ʻana o ka waihoʻoluʻu a i ʻole nā ​​​​waiwai o nā puaʻa i ka hana ʻana i nā mahana.ʻO ka maʻamau, ʻo ka manawa pale wela o ka puaʻa e koi ʻia e 4 ~ 10min.ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka pale ʻana o nā puaʻa inorganic a ʻaʻole maʻalahi ke hoʻoheheʻe ʻia i nā mahana hoʻololi i ka plastik, ʻoiai ʻaʻole maikaʻi ka wela o nā puaʻa organik.

(4) Ke kū'ē kū'ē maikaʻi.
ʻO ka neʻe ʻana o ka puaʻa e pili ana i ke ʻano o ka launa pū ʻana o nā huahana plastik kala me nā mea paʻa ʻē aʻe, nā wai, nā kinoea a me nā mea ʻē aʻe, a neʻe nā puaʻa mai loko mai o ka plastic i ka ʻili manuahi o ka huahana a i ʻole nā ​​mea i pili me ia.ʻO ka neʻe ʻana o nā kala i loko o nā plastics e hōʻike ana i ka hoʻohālikelike maikaʻi ʻole ma waena o nā kala a me nā resins.ʻO ka mea maʻamau, ʻoi aku ka nui o ka wai o nā puaʻa a me nā puaʻa organik, aʻo nā puaʻa inorganic he haʻahaʻa ka wai.

(5) Kūleʻa māmā maikaʻi a me ka pale ʻana i ka wā.
ʻO ka māmā a me ka hikiwawe e pili ana i ke kūpaʻa kala ma lalo o ka mālamalama a me nā kūlana kūlohelohe.ʻO ka wikiwiki māmā e pili ana i ke ʻano molekala o ka mea kala.Loaʻa i nā kala like ʻole nā ​​hana molekala a me ka māmā māmā.

(6) Ke kū'ēʻana i ka waika maikaʻi, ke kū'ē alkali, ke kū'ē'ē a me ke kū'ē kemika.
Hoʻohana pinepine ʻia nā huahana plastik no ka mālama ʻana i nā kemika a me ka lawe ʻana i nā kemika e like me ka waikawa a me ka alkali, no laila e noʻonoʻo ʻia ke kūpaʻa a me ka alkali o nā puaʻa.
