Ua noʻonoʻo paha ʻoe i ka mea e paʻa mau ai kāu t-shirt kiʻi pop a i ʻole nā ​​​​hōʻailona ʻoihana no nā makahiki? E hui i ka paʻi paʻi kiʻi pale - ka hero unsung blending science and creativity e hoʻololi i nā hoʻolālā i ke kiʻi paʻa. ʻO kēia hui pū ʻana o nā resins, nā puaʻa, a me nā mea hoʻohui ke kaulike i ka kahe kūpono (no ka hele ʻana o ka pale maʻemaʻe) a me ka viscosity ikaika (e pale i ke koko), e hāʻawi ana i nā ʻano ʻoi aku ma waena o nā lole, plastics, aniani, a me nā mea hou aku. ʻO ka manaʻo palupalu paha o nā ʻano wai a i ʻole ka uhi wiwo ʻole o nā pastes synthetic, ʻo ia ka iwi kuamoʻo o nā mea hana liʻiliʻi a me ka hana nui, e hoʻopau ana i ka huhū o nā hoʻolālā mae a i ʻole nā ​​​​papa like ʻole e hōʻeha nei i nā papahana amateur.​

Aia ka mea kilokilo i kona ʻokoʻa: aia kahi paʻi no kēlā me kēia papahana. ʻO nā koho wai-friendly Eco-friendly (≤50g/L VOCs) he mea kūpono no nā lole a me nā huahana keiki, aʻo nā pāpaʻi i hoʻopaʻa ʻia i ka solvent maloʻo i loko o 5-10 mau minuke no ka hoʻohana ʻana i ka ʻoihana paʻakikī. Hoʻolaʻa nā ʻano ʻokoʻa UV-curable i 1-3 kekona no nā hopena 3D kiʻekiʻe ma luna o nā mea uila, a ʻo nā paʻi thermoset e kū i ka 50+ holoi ma hope o ka hoʻōla wela (140-160 ℃) - kūpono no nā lole haʻuki. E hoʻohui i nā pāpaʻi metala, puff, a i ʻole ka hoʻokuʻu ʻana i loko o ka hui ʻana, a loaʻa iā ʻoe kahi mea hana e hoʻoulu ai i ka hana hou, mai nā hiʻohiʻona ʻehaʻeha a hiki i ke ʻano keaka. Loaʻa ka poʻe hoʻomaka i nā ʻano haʻahaʻa mānoanoa (10-30μm) e laha maʻalahi me ka ʻole o ka hoʻopaʻa ʻana i nā pale, e hiki ai i ka poʻe hobbyists nā hopena ʻoihana.

ʻAʻole pili wale ka pāpaʻi hou i ka hana - pili ia i ka holomua. He 800-12,000 mPa·s viscosity, ≥4B adhesion, a me 1,000-hola UV ke kū ʻana i ka wā ʻino no nā hōʻailona waho a i ʻole ka hoʻohana pinepine ʻana i nā lole hana. ʻOi aku, ʻo ka hoʻomau ʻana ke kū i ke kahua waena: formaldehyde-free, plasticizer-free koho a me ka hoʻopili ʻana i ka pahu kaiaola (hoʻololi i nā bākeke PVC hoʻohaumia) hōʻemi i nā ʻōpala a me nā kumukūʻai. Mai nā kāʻei hui maʻamau a i nā mea hoʻolaha branded, nā menus hale ʻaina a i nā decals automotive, hoʻololi pono ia i nā pono like ʻole. No nā mea hana a me nā mea hana like, ʻaʻole he mea wale ka paʻi kūpono - ʻo ia ke kī i ka wehe ʻana i nā mea pau ʻole a lōʻihi e hoʻohui ai i ka maikaʻi, ka noʻonoʻo, a me ka pono.
