Ka Wehewehena a me nā ʻAno o ka Pena Enamel Acrylic
ʻO ka pena enamel acrylic kahi ʻano uhi kahi ʻo ka resin acrylic ka mea hana kiʻiʻoniʻoni nui. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka wā, ke kūpaʻa i ka pala kemika, a me nā waiwai hoʻonaninani. Wahi a nā hopena hulina, loaʻa i ka pena enamel acrylic nā waiwai anti-corrosion, pale wai, a me ka pale ʻaila maikaʻi loa, a hiki ke pale pono i ka ʻili o nā mea mai ka mana a me ka hōʻino ʻana o ke kaiapuni waho. Eia kekahi, ma ke ʻano he pena acrylic ʻelua ʻāpana, hoʻohana ka pena enamel polyurethane acrylic i ka hopena ma waena o ka -OH o ka acrylic a me ka -NCO o ka polyurethane e hoʻopili a hoʻōla i ka kiʻiʻoniʻoni, a he kūpaʻa maikaʻi loa i ka ʻelemakule, kūpaʻa i ka holoi wai, nā waiwai kino, hoʻopaʻa kala, a me ka paʻa ʻana o ka mālamalama.
ʻO ka hana pale wai o ka pena enamel acrylic
- Loaʻa i ka pena acrylic nā waiwai pale wai maopopo a kūpono ia no nā hiʻohiʻona e pono ai ka pale ʻana i ka pala a me ka wai, e like me nā lako hana kila, nā alahaka, nā moku, ka metallurgy, nā ipu, nā mīkini kūkulu, nā ʻano kaʻa halihali like ʻole, a pēlā aku. Eia kekahi, loaʻa i ka pena polyurethane acrylic nā waiwai pale wai a me ke kūpaʻa alkali, a kūpono ia no nā ʻoihana me ka ʻino nui.
- Hiki ke manaʻo ʻia ka enamel acrylic (e like me ka pena magnetic acrylic, ka pena magnetic polyurethane acrylic) he ʻano pena me nā waiwai wai ʻole. ʻO kona hiʻohiʻona wai ʻole e kūpono ia no nā hiʻohiʻona kahi e pono ai ka pale ʻana mai ke komo ʻana o ka wai, me ka loaʻa pū ʻana o nā pono e like me ke kūpaʻa i ka pala a me ke kūpaʻa i ka ʻelemakule.
ʻO ke kumu nui o ka hana pale wai
He mau waiwai wai maikaʻi loa ko ka enamel acrylic (i ʻike ʻia hoʻi he pena acrylic), a ua hoʻohana nui ʻia a hōʻoia ʻia kēia hiʻohiʻona ma ke kahua o ka anti-corrosion ʻoihana. Eia kahi loiloi kikoʻī a me nā manaʻo hoʻohana:
ʻO ke kumu nui o ka hana pale wai
- Nā ʻano mea
Hoʻohana ka pena enamel acrylic i ka resin acrylic ma ke ʻano he mea hana kiʻiʻoniʻoni nui. Loaʻa i kona ʻano molekala nā waiwai hydrophobic, a ma hope o ka hoʻōla ʻana, hiki iā ia ke hana i kahi kiʻiʻoniʻoni mānoanoa a hoʻomau, e pale pono ana i ke komo ʻana o ka wai. Hoʻohui pū kekahi mau huahana i ka chlorosulfonated polyethylene rubber a i ʻole nā mea i hoʻololi ʻia i ka polyurethane (e like me ka pena magnetic acrylic polyurethane), e hoʻoikaika hou ana i ke kūpaʻa wai a me ka pale ʻana i ka makū.
No ka laʻana, hiki i ka emulsion acrylic wai-hoʻokumu ʻia ma o ka hoʻolālā hui hydrophobic kūikawā ke pale i nā mole wai mai ke komo ʻana i ka substrate ma hope o ka maloʻo ʻana.
ʻOi aku ka maikaʻi o ko lākou kūpaʻa wai i nā huahana i hana ʻia me ka solvent (e like me ka pena magnetic metala acrylic) a kūpono hoʻi no nā wahi pulu no ka manawa lōʻihi.
- Hōʻoia hana
Ua hōʻike ʻia nā hoʻokolohua hoʻokolohua ma hope o ka hoʻomoʻu ʻia ʻana no 24 mau hola, ʻaʻohe ʻili a hāʻule paha o ka pena enamel acrylic ma luna o ka ʻili.
Ma nā papahana o waho (e like me nā alahaka, nā moku, a me nā hale kila), hiki i kāna hana wai ʻole ke pale aku i ka ʻānai ʻana o ka wai ua a me ka wai kai, a laila e hoʻolōʻihi ai i ke ola o ke kahua.
