Wehewehe Huahana
He hui i hoʻohana nui ʻia ʻo Polyurea i hoʻopili pono ʻia i ka pale ʻana i ka palaho o nā pahu mālama, ka pale wai ʻana i nā hale sima e like me nā wahi kaʻa, nā waihona wai, a me nā tunnels, a ma ke ʻano he mau mea hoʻopiha hui a i ʻole nā mea hoʻopaʻa.
- Hiki ke helu ʻia kahi papa inoa lōʻihi o nā mea i hoʻohana ʻia e like me nā uhi pale wai. No kekahi mau kenekulia, ʻo ke koho wale nō i loaʻa he mau huahana asphalt. I ke kenekulia 20, ua hoʻomohala ʻia nā mea ʻē aʻe he nui, me ka epoxy a me ka vinyl ester.
- ʻO Polyurea ka ʻenehana uhi hou loa i hoʻomohala ʻia. ʻO kēia mea, i hoʻomohala ʻia no ka ʻoihana kaʻa i ka hopena o nā makahiki 1980, ua hoʻohana nui ʻia i nā ʻano like ʻole. Ma muli o kona hoʻōla wikiwiki ʻana, ke kūpaʻa ʻana i ka pala, a me ke kūpaʻa ʻana i ka ʻaʻahu, ua holomua nui ia i ka hana ʻenekinia pale wai i nā makahiki he 10 i hala.
- I ka wā i hana ʻia ai ka polyurea, ua manaʻolana ʻia he mea polyurethane i emi iki ka maʻalahi i ka wai. Ma ka hoʻololi ʻana i nā hui carboxyl i loko o ka polyurethane me nā hui amino, ua loaʻa ka huahana a mākou e kapa nei he polyurea. ʻOi aku ka liʻiliʻi o ka maʻalahi o kēia huahana i ka wai ma mua o nā uhi polyurethane ʻē aʻe.
- ʻElua ʻano maʻamau o ka Polyurea. Hoʻohana pinepine ʻia ka polyurea ʻala. Hiki ke ʻokoʻa loa ka hana kino o kēia huahana, no laila he nui nā noi like ʻole. ʻO ka ʻoiaʻiʻo, ʻo ka hemahema wale nō o kēia uhi ʻana, ʻo ia ka paʻa ʻole o ka UV. ʻO kekahi ʻano, ʻo ia ka polyurea aliphatic. Ma ka hoʻohana ʻana i nā ʻano kemika like ʻole e hoʻolilo iā ia i paʻa UV maikaʻi aʻe, ua uku ʻia kahi uku hoʻopaʻi. ʻO ke kumukūʻai o kēia polyurea he pālua ia o ka polyurea ʻala.
Nā hiʻohiʻona huahana
ʻO nā uhi Polyurea, ma ke ʻano he ʻano hou o ka uhi hana kiʻekiʻe, he nui nā ʻano kupaianaha.
- He haʻaheo ia i nā waiwai kino maikaʻi loa, e like me ke kūpaʻa maikaʻi o ka ʻaʻahu, e hiki ai i ka uhi ke mālama i kona kūpaʻa a me ka hopena pale no ka manawa lōʻihi ma nā wahi i hoʻopilikia pinepine ʻia e ka friction a me ka ʻaʻahu;
- I ka manawa like, he kūpaʻa hopena koʻikoʻi kona, e pale pono ana i nā mana hopena o waho a pale i ka ʻili o ka mea i uhi ʻia mai ka hōʻino.
- Ma ke ʻano o nā waiwai kemika, hōʻike nā uhi polyurea i ke kūpaʻa koʻikoʻi i ka pala. Inā paha e kū ana i ka ʻino ʻana o nā waikawa, alkalis, a i ʻole ma nā wahi kemika ʻino e like me ke kiʻekiʻe o ka makū a me ka paʻakai kiʻekiʻe, hiki iā lākou ke noho paʻa no ka manawa lōʻihi a ʻaʻole hiki ke hana ʻia i nā hopena kemika e hōʻino ai i ka uhi.
- Eia kekahi, he kūpaʻa maikaʻi kona i ke aniau, e mālama ana i kona kūpaʻa hana i nā ʻano aniau like ʻole, e like me ke kiʻekiʻe o ka mahana, nā mahana haʻahaʻa, a me ka radiation ultraviolet, me ka ʻole o ka ʻike ʻana i nā pilikia e like me ka pauka ʻana, ka hoʻololi ʻana o ke kala, a i ʻole ka ʻili ʻana ma muli o nā loli o ke aniau. He wikiwiki loa ka wikiwiki o ka hoʻōla ʻana o nā uhi polyurea, kahi e hoʻomaikaʻi nui ai i ka pono o ke kūkulu ʻana a hiki ai ke hoʻopau ʻia ka uhi ʻana a hoʻohana ʻia i loko o kahi manawa pōkole.
- Eia kekahi, he pipili maikaʻi kona i nā ʻano substrates like ʻole, hiki ke hoʻopili pono i nā ʻili o nā metala, ka sima, ka lāʻau, a me nā mea ʻē aʻe, e hana ana i kahi papa pale paʻa a paʻa.
NĀ PONO O KA HUAHANA
- ʻO kekahi o nā kumu i kaulana koke ai nā uhi polyurea, ʻo ia ko lākou ʻano like ʻole o nā waiwai maikaʻi loa i hōʻike ʻia. Ua ʻōlelo ākea ka pūnaewele Polyurea.com e pili ana i nā waiwai kino i loaʻa, ʻaʻohe uhi ʻē aʻe ma ka honua e hiki ke hoʻokūkū me ka polyurea. Ma ka hoʻoponopono ʻana i ke ʻano, hiki i nā huahana polyurea ke loaʻa kahi ākea loa o nā waiwai, mai ka elongation kiʻekiʻe a i ka ikaika tensile maikaʻi loa, akā pili kēia i ke ʻano o ka mea a me ka hoʻopili pololei ʻana. Loaʻa iā Polyurea ka hoʻopili maikaʻi loa i nā substrates like ʻole me ka sima, ka metala, a me ka lāʻau, ʻoiai me ka ʻole o ka primer, a hiki ke hoʻohana ʻia i nā wahi me nā ʻano like ʻole o ka mahana a me ka haʻahaʻa. ʻO ka pōmaikaʻi kupaianaha loa o ka polyurea ʻo ia kona hoʻōla wikiwiki loa. Ke hoʻopili ʻia, hiki i ka polyurea ke hiki i ka mānoanoa e pono ai i hoʻokahi ʻaʻahu, ʻoi aku ka wikiwiki ma mua o ka hoʻohana ʻana i nā uhi kuʻuna, e ʻae ana i ka mea nona e hoʻomau i ka hoʻohana ʻana i ka hale a me ka hōʻemi ʻana i nā pohō ma muli o ka downtime.
- Hiki i ka mānoanoa o kahi hoʻopili hoʻokahi o nā uhi polyurea ke loaʻa mai ka 0.5mm a i ka 12.7mm, a ʻo ka manawa hoʻōla mai ka koke a i kahi 2 mau minuke, kahi mea e kōkua ai i ka hiki koke ʻana i kahi kūlana hiki ke hoʻohana.
- Ma ke ʻano he uhi ʻili mānoanoa e hoʻōla wikiwiki ana, i ka wā e pono ai kahi pale wai membrane humuhumu a paʻa hoʻi, he koho kūpono ka polyurea. Hiki ke hoʻokō ʻia nā waiwai ʻē aʻe, e like me ke koi ʻana i ka anti-slip a me ke ʻano o ka ʻili, ma o kekahi mau ʻano. Hiki ke pena ʻia ka uhi a hiki ke hoʻohana ʻia ma nā wahi e hoʻokō ai i nā koi wai inu.
- Ma muli o kona ʻano hana like ʻole, he ākea loa nā noi o ka polyurea. ʻO ka uhi o loko o nā pahu mālama, nā papa pale lua, a me ka pale ʻana o ka ʻili o nā alahaka nā manawa i hoʻohana nui ʻia no kēia ʻano mea. ʻO ka ʻoiaʻiʻo, ʻaneʻane palena ʻole nā mea hiki ke hoʻohana ʻia ka polyurea.
- Hoʻopilikia pinepine ʻia nā pahu o nā hale hana hoʻomaʻemaʻe wai ʻino e ka vortex, ka holoi ʻana, a me ka nui o ke kinoea hydrogen sulfide i ka wā o ke kānana ʻana, ka hoʻohuihui ʻana, a me nā kaʻina hana dehydration. Hiki i ka hoʻohana ʻana i ka polyurea ke hāʻawi i ka anti-wear e pono ai, ke kū'ē i nā kemika, a me ke kū'ē i ka hopena, a hiki ke hoʻihoʻi koke i ka hale hana i ka hana, ʻoi aku ka wikiwiki ma mua o nā ʻano hana ʻē aʻe.
- Ke hoʻopili ʻia i nā alahaka a me nā wahi ʻē aʻe i pili i ka haʻalulu a me ka neʻe ʻana, ʻo ka maʻalahi o ka polyurea kekahi pono ʻē aʻe ma mua o kēlā mau uhi lahilahi a emi iki ka maʻalahi e like me ka epoxy.
Nā hemahema o ka huahana
- ʻOiaʻiʻo, he mau hemahema nō hoʻi ko ka polyurea. He pipiʻi iki nā lako e pono ai no ka hoʻopili ʻana i nā uhi polyurea, mai $15,000 a i $50,000 a ʻoi aku paha. Hiki i ke kahua kūkulu kelepona i lako pono ʻia ke kumukūʻai a hiki i $100,000.
- ʻOi aku ke kiʻekiʻe o ke kumukūʻai o nā mea polyurea ma mua o nā uhi ʻē aʻe. ʻOi aku ke kiʻekiʻe o ke kumukūʻai mua ma mua o ka epoxy. Eia nō naʻe, ʻoiai ʻo ke ola lawelawe o nā uhi polyurea he 3 a 5 mau manawa o nā huahana ʻē aʻe, aia nō nā pono o ke kumukūʻai kūpono i ka wā o ke ola lawelawe.
- E like me nā mea pale wai ʻē aʻe, hiki i ke kūkulu kūpono ʻole ke alakaʻi i ka hāʻule ʻana o ka noi. Eia nō naʻe, kiʻekiʻe loa nā koi no ke kūkulu ʻana me nā uhi polyurea. He mea koʻikoʻi loa ka mālama ʻana i ka ʻili e like me ke oneblasting a i ʻole ka priming no ka polyurea. ʻAneʻane pili ʻole ka hapa nui o nā papahana uhi polyurea i hāʻule ʻole i ka polyurea ponoʻī, akā ua hana ʻia e ka mālama ʻili kūpono ʻole a maikaʻi ʻole paha.
Kūkulu ʻana
- ʻO ka hapa nui o ka polyurea i hoʻohana ʻia no ka pale wai ʻana ua kūkulu ʻia me ka hoʻohana ʻana i nā lako pīpī multi-component. ʻO ka maʻamau, hoʻohana ʻia kahi ʻōnaehana ʻelua-ʻāpana, me ka hui ʻana o ka amino resin a me ka mea isocyanate e waiho kaʻawale ʻia i loko o nā pahu 50-galani. I ka wā o ke kūkulu ʻana ma kahi hana, hoʻoili ʻia nā mea mai loko mai o nā pahu 50-galani i ka pahu o nā lako pīpī a hoʻomehana ʻia i kahi mahana kūpono (60-71°C). A laila, hoʻouna ʻia ka isocyanate a me ka polyol resin ma o kahi hose wela i ka pū pīpī.
- Hoʻomalu pono ʻia ka lakio o nā mea ʻelua, ma ka lākiō 1:1.
- Ua ana ʻia ka manawa hoʻōla o ka polyurea i kekona, no laila hiki ke hoʻohuihui ʻia kēia mau kemika i ka manawa koke e haʻalele ai lākou i ka pū pīpī; inā ʻaʻole, e hoʻōla a paʻakikī lākou i loko o ka pū pīpī.
- Kūʻai aku kekahi mau mea hana i nā ʻāpana pīpī piha holoʻokoʻa, me nā mea hana a me nā lako āpau, i hoʻokomo ʻia ma nā trailers a i ʻole nā moena kalaka.
