ʻO nā mea āpau e pono ai ʻoe e ʻike e pili ana i nā waiwai waiwai PS no ka mea lawe lipine maikaʻi loa

ʻO ka mea polystyrene (PS) kahi koho kaulana no ka mea lawe lipine maka ma muli o kona mau waiwai kūikawā a me kona ʻano. Ma kēia ʻatikala ʻatikala, e nānā pono mākou i nā waiwai waiwai PS a kūkākūkā pehea lākou e pili ai i ke kaʻina hana.

ʻO ka mea PS kahi polymer thermoplastic i hoʻohana ʻia i nā ʻoihana like ʻole e like me ka hoʻopili ʻana, ka uila a me ka automotive. I loko o ka lawe lipine hana he koho maikaʻi loa ia ma muli o kona hoʻokele waiwai, rigidity a me ka pale wela.

I ka hoʻohana ʻana i nā mea PS ma ke ʻano he mea lawe lipine maka, pono e hoʻomaopopo i kona ʻano. ʻO ka mua, he polymer amorphous ʻo PS, ʻo ia hoʻi, ʻaʻohe ona ʻano crystalline. Hoʻopili kēia ʻano i kona mau ʻano mechanical a me ka wela, ʻo ia hoʻi ka stiffness, brittleness, opacity a me ka pale wela.

ʻO ka hui kūʻokoʻa o nā waiwai o nā mea PS e kūpono iā lākou no ka ʻoihana uila. ʻO ke kikoʻī, ʻo kona kūpaʻa ʻana i ka moisture e hōʻoia i ka palekana o nā mea uila i ka wā o ka lawe ʻana a i ʻole ka mālama ʻana. ʻO ia ke kumu i koho nui ʻia ai nā mea PS no ka mea lawe lipine maka.

ʻO kekahi hiʻohiʻona koʻikoʻi o ka mea PS ʻo kona formability. Mahalo i kona haʻahaʻa hoʻoheheʻe haʻahaʻa, hiki i ka PS ke hana maikaʻi loa, hiki i ka hoʻopau kiʻekiʻe kiʻekiʻe a me nā manawa hana maikaʻi i ka wā e hana ai i nā mea maka.

ʻO ka hana hoʻoheheʻe ʻana o PS
1. He haʻahaʻa haʻahaʻa ka haʻahaʻa haʻahaʻa o ka mea Amorphous, ʻaʻole pono e hoʻomaloʻo piha ʻia, ʻaʻole maʻalahi ka decompose, akā loaʻa ka coefficient hoʻonui thermal nui a hiki i ke koʻikoʻi kūloko. Loaʻa iā ia ka wai maikaʻi a hiki ke hoʻoheheʻe ʻia me ka mīkini hoʻoheheʻe a i ʻole plunger.
2. He kūpono ka hoʻohana ʻana i ka wela o ka mea kiʻekiʻe, ka wela o ka poni kiʻekiʻe, a me ke kaomi haʻahaʻa haʻahaʻa. ʻO ka hoʻolōʻihi ʻana i ka manawa injection he mea maikaʻi ia e hōʻemi i ke koʻikoʻi o loko a pale i ka shrinkage cavity a me ka deformation.
3. Hiki ke hoʻohana ʻia nā ʻano ʻīpuka like ʻole, a ua hoʻopili ʻia ka ʻīpuka me ka ʻāpana plastik i loko o kahi arc e pale i ka pōʻino i ka ʻāpana plastik i ka wā o ka puka. He nui ka slope demoulding, a ua like ka ejection. ʻO ka mānoanoa o ka pā o ka ʻāpana plastik he ʻano like ʻole, a ʻaʻohe mea hoʻokomo e like me ka mea hiki, e like me Inserts pono e hoʻomehana ʻia.
ʻO ka hōʻuluʻulu ʻana, he koho maikaʻi loa ka mea PS no ka mea lawe lipine maka no kona ʻano ponoʻī a me kona ʻano. Ma ke ʻano he polymer thermoplastic, ʻoi aku ka maikaʻi o ka PS, paʻa a me ka wela. Hoʻohui ʻia, ʻoi aku ka maikaʻi o kona pale ʻana i ka wai no ka pale ʻana i nā mea uila i ka wā o ka lawe ʻana a me ka mālama ʻana.

ʻO ka hoʻomaopopo ʻana i nā waiwai waiwai PS a me kā lākou hopena i ke kaʻina hana he mea koʻikoʻi ia i ka hoʻonui ʻana i ka hana lipine carrier. Ma ke koho ʻana i nā mea waiwai PS premium, hiki iā mākou ke hana i nā lipine halihali o ka maikaʻi a me ka maikaʻi kiʻekiʻe, e hōʻoiaʻiʻo ana i ka kūleʻa o kekahi hana uila uila.
