He aha ka pai kilika?ʻO ka paʻi pale ke kaomi ʻana i ka ʻīnika ma kahi pale stencil e hana i kahi hoʻolālā paʻi.He ʻenehana ākea i hoʻohana nui ʻia i nā ʻoihana like ʻole.Kapa ʻia ke kaʻina hana i ka paʻi pale a i ʻole ka paʻi pale, akā pili kēia mau inoa i ke ʻano like.Hiki ke hoʻohana ʻia ka paʻi pale ma nā ʻano like ʻole o ka substrate, akā inā ʻaʻole i ʻae ʻia a i ʻole poʻe.Nānā kēia ʻatikala i nā mea like ʻole i hiki ke hoʻohana ʻia i nā ʻano paʻi pale, ʻo ia hoʻi nā plastics.
He aha nā mea hiki ke hoʻohana ʻia no ka paʻi kilika?
Hoʻohana mua ʻia ka paʻi pale ma ka lole a me nā mea pepa.Hiki iā ia ke paʻi i nā kiʻi a me nā mamana ma nā lole e like me ke siliki, ka pulupulu, ka polyester a me ka organza.Ua ʻike maikaʻi ʻia ka paʻi pale, hiki ke hoʻohana ʻia kēlā me kēia lole e koi ana i ke ʻano o ka paʻi ʻana no ka paʻi pale.Akā, kūpono nā ʻīnika ʻokoʻa no nā mea like ʻole, me nā seramika, lāʻau, aniani, metala a me ka plastic.
ʻO ka paʻi siliki koe wale nō ka hoʻohana ʻia i loko o nā lole a i ʻole nā mea pepa, i kēia manawa hoʻohana pū ka mea hana i loko o nā huahana plastik i mea e nani ai.
ʻO nā mea plastik i kūpono no ka paʻi siliki loaʻa kēia:
ʻO ka Polyvinyl chloride: ʻO ka PVC ka maikaʻi o ka waihoʻoluʻu ʻulaʻula, ka pale ʻana i ka haki, ka waikawa a me ke kūpaʻa alkali, a me ke kumu kūʻai haʻahaʻa.Eia nō naʻe, ʻo kekahi mau mea i hoʻohui ʻia i ka wā o ka hana ʻana o PVC he mea ʻawaʻawa, no laila ʻaʻole hiki ke hoʻohana ʻia nā huahana PVC no nā ipu meaʻai.
ʻO Acrylonitrile Butadiene Styrene: ʻO ka plastik resin ABS kahi mea ʻenekinia i hoʻohana nui ʻia i nā televise, nā helu helu a me nā huahana ʻē aʻe i nā makahiki i hala.ʻO kona hiʻohiʻona he maʻalahi ka hana a me ke ʻano.Hoʻohana nui ʻia ka polyethylene plastic a hiki ke hana ʻia i nā huahana like ʻole ma o ka extrusion, injection molding a me nā kaʻina hana ʻē aʻe.
ʻO Polypropylene: ʻO PP kekahi o nā ʻano plastik koʻikoʻi i kūpono i nā ʻano hana hana a pau.Hiki iā ia ke hana i nā paipu like ʻole, nā pahu, nā ipu, nā kiʻiʻoniʻoni, nā fibers, etc.
Pehea ka hana ʻana o ka paʻi paʻi kiʻi kiʻi?
Loaʻa nā ʻano hana like ʻole o ka paʻi pale, akā hoʻohana lākou a pau i ka ʻenehana kumu like.Aia ka pale i kahi mākia i hohola ʻia ma luna o kahi kiʻi.Hiki i ka mesh ke lilo i polymer synthetic e like me ka nylon, me nā puka mesh ʻoi aku ka liʻiliʻi a me ka liʻiliʻi i hoʻohana ʻia no nā hoʻolālā e koi ana i nā kikoʻī hou aku.Pono e kau ʻia ka mānoanoa ma luna o kahi kiʻi i hoʻopaʻa ʻia e hana.Hiki ke hana ʻia ke kiʻi e paʻa ana i ka mesh mai nā mea e like me ka lāʻau a i ʻole ka aluminika, ma muli o ka paʻakikī o ka mīkini a i ʻole nā kaʻina hana a ka mea hana.Hiki ke hoʻohana ʻia kahi tensiometer no ka hoʻāʻo ʻana i ka ʻoluʻolu o ka pūnaewele.
E hana i ka la'ana ma ka pale 'ana i kekahi hapa o ka pale ma ka 'ole o ka ho'olālā makemake.ʻO nā wahi ākea kahi e ʻike ʻia ai ka ʻīnika ma ka substrate.Ma mua o ka paʻi ʻana, pono e hele ke kiʻi a me ka pale ma ke kaʻina paʻi mua kahi e "hoʻopaʻa ʻia" ai ka emulsion ma ka pale.
Ma hope o ka maloʻo ʻana o ka hui ʻana, ʻike ʻia ia i ke kukui UV ma o kahi kiʻiʻoniʻoni i paʻi ʻia me ka hoʻolālā makemake.Hoʻopaʻakikī ka ʻike i ka emulsion ma nā wahi i hōʻike ʻia akā hoʻopalupalu i nā ʻāpana i ʻike ʻole ʻia.A laila holoi ʻia lākou me kahi ʻūhā wai, e hana ana i nā wahi maʻemaʻe i loko o ka pā ma ke ʻano o ke kiʻi i makemake ʻia, e hiki ai i ka ʻīnika ke hele.He kaʻina hana kēia.
ʻO kaʻili e kākoʻo ana i ka lole i kapa pinepineʻia he pallet i ka paʻi lole.Hoʻopili ʻia me ka lipine pallet ākea e pale ai i ka pallet mai ka leaka ʻana o ka ʻīnika makemake ʻole a hiki ke hoʻohaumia ʻia ka pallet a i ʻole ka hoʻololi ʻana o ka inika makemake ʻole i ka substrate e hiki mai ana.
Nā noi paʻi pale plastik
I nā makahiki i hala iho nei, ua hoʻonui nui ʻia ka ʻenehana uila paʻi no ka uhi kiʻiʻoniʻoni lahilahi no nā mea uila ʻoi aku ka ʻoi aku ka nui o nā hale kūloko, hoʻomaikaʻi i ke kūlana paʻi no ke kākoʻo ʻana i ka miniaturization o nā mea uila.ʻO ka hopena, pono e hoʻomohala ʻia ka paʻi pale e hoʻokō i kēia mau koi.
ʻOkoʻa nā plastics ʻokoʻa nā noi plastik.Paʻi pale paʻi me ka polypropylene no nā pahu, ʻeke ʻeke, pepa a me nā hae.Hoʻohana ʻia ka Polycarbonate e hana i nā DVD, nā CD, nā ʻōmole, nā lens, nā hōʻailona a me nā hōʻike.Hoʻohana maʻamau no ka polyethylene terephthalate me nā ʻōmole a me nā hōʻike backlight.Hoʻohana pinepine ʻia ka polystyrene i loko o nā pahu pahu a me nā tile kaupaku.Hoʻohana no ka PVC me nā kāleka hōʻaiʻē, nā kāleka makana a me nā noi hana.
Hōʻuluʻulu manaʻo
ʻO ka paʻi paʻi kiʻi ʻana he ʻano hana maikaʻi e loaʻa ai ka hoʻohana ʻana i nā noi like ʻole.Manaʻolana mākou ua wehewehe kēia ʻatikala i ke ʻano o ke kaʻina hana a ua wehewehe i kekahi o kāna hoʻohana ʻana me nā mea plastik.Inā makemake ʻoe i ka paʻi pale a i ʻole nā lawelawe hōʻailona ʻāpana ʻē aʻe,e hoʻokaʻaʻike i kā mākou kūʻaie kiʻi i kāu ʻōlelo manuahi, ʻaʻohe kuleana.
