ʻO ka Sila Polyurethane vs. Silicone Sealant: ʻO wai kāu e koho ai?
ʻO ke koho ʻana i ka sila kūpono kekahi o nā hoʻoholo koʻikoʻi loa i ke kūkulu ʻana, ka ʻenekinia façade, nā papahana ʻoihana, a me ka hana ʻoihana. ʻO ʻelua o nā huahana i hoʻohana nui ʻia, ʻo ia ka sila polyurethane (PU) a me ka sila silicone, akā naʻe, he nui nā mea hana a me nā mea kūʻai aku e hakakā nei e hoʻoholo i ka mea e hana maikaʻi ana no kā lākou mau noi kikoʻī.
ʻO ka ʻoiaʻiʻo, ʻaʻohe mea lanakila no ke ao holoʻokoʻa. Hana ʻia kēlā me kēia mea me nā ʻano kemika like ʻole e hoʻolilo iā ia i mea maikaʻi loa i nā wahi like ʻole.
Inā pili kāu papahana i nā hui hoʻonui sima, nā alaloa, nā papa kaʻa, nā papahele ʻoihana, nā alahaka, a i ʻole nā wahi kaʻa ukana kaumaha,mea hoʻopaʻa polyurethaneʻo ia pinepine ke koho kūpono loa.
Inā kālele ana kāu papahana i nā paia pale aniani, ka aniani puka makani, ka pale ʻana i waho o ka wā, a i ʻole ka hōʻike UV lōʻihi,mea hoʻopaʻa siliconema ke ʻano laulā hāʻawi i ke kūpaʻa maikaʻi ʻana i ka wā.
Hoʻohālikelike kēia alakaʻi i nā sila polyurethane a me silicone mai kēlā me kēia kuanaʻike koʻikoʻi—me ka hoʻopili ʻana, ka lōʻihi, ka hiki ke neʻe, ke kū'ē ʻana i ka UV, ka pena ʻana, nā kumukūʻai mālama, a me nā noi i ʻōlelo ʻia—e kōkua ana i nā mea hana ʻaelike, nā mea kākau hale, nā mea hoʻolaha, a me nā mea kūʻai OEM e hana i nā hoʻoholo kūʻai naʻauao.
ʻO Polyurethane vs. Silicone ma kahi Nānā
Hāʻawi nā sila polyurethane i ka hoʻopili ikaika ʻana i nā mea porous, ka ikaika mechanical kiʻekiʻe, ka pena maikaʻi loa, a me ke kūpaʻa abrasion kiʻekiʻe. Hāʻawi nā sila silicone i ke kūpaʻa UV maikaʻi loa, ke kūpaʻa i ka wā, a me ka elasticity lōʻihi, e kūpono ai no ka glazing a me nā noi façade waho.

He aha ka mea hoʻopaʻa polyurethane (PU)?
He mea hoʻopaʻa elastomeric hoʻōla wai ka polyurethane sealant i hana ʻia e hāʻawi i ka hoʻopili ikaika, ka ikaika mechanical kiʻekiʻe, a me ka maʻalahi maikaʻi loa. Hoʻopili maikaʻi loa ia i nā mea kūkulu porous e like me:
• Sima
• Sima
• Hana Pā pōhaku
• Pōhaku
• Piliki
• Mea hao
• Alumini
• Ke kila
• Lāʻau
ʻAʻole e like me ka silicone, hoʻopili kemika ka polyurethane i nā substrates he nui me ka ʻole o ka mōhai ʻana i ka ikaika o ke kūkulu ʻana, e lilo ia i hoʻokahi o nā sila hilinaʻi loa no ka ʻenekinia kīwila a me ke kūkulu ʻana i nā hana kaumaha.
Hoʻohana pinepine ka poʻe loea i nā sila PU kahi e pono ai ka neʻe ikaika, ke kūpaʻa i ka hopena, a me ke kūpaʻa mechanical.
No kahi laina piha o nā huahana polyurethane papa kūkulu, e kipa i kā mākou Hōʻiliʻili Huahana Polyurethane Sealant.
Nā Pōmaikaʻi Koʻikoʻi o ka Sealant PU
1. Hoʻopili maikaʻi loa
Hoʻokumu ka Polyurethane i nā pilina ikaika loa me nā mea kūkulu porous.
ʻO kēia ka mea e lilo ai ia i mea makemake nui ʻia no:
• Nā papa sima
• Nā hui hoʻonui
• Nā hale kaʻa
• Papahele ʻoihana
• Nā hui alahaka
• Ke kūkulu ʻana i ka tunnel
2. Paʻakikī o ke Kahakai Kiʻekiʻe
Ke hoʻohālikelike ʻia me ka silicone, loaʻa i ka polyurethane ka paʻakikī Shore A kiʻekiʻe ma hope o ka hoʻōla ʻana.
ʻO nā pono e komo pū ana:
• ʻOi aku ka maikaʻi o ke kūpaʻa ʻana i ka hopena
• Hoʻemi ʻia ka pōʻino o ka ʻili
• Ola lawelawe lōʻihi
• ʻOi aku ka maikaʻi o ka hiki ke hāpai i nā ukana
3. ʻIli hiki ke pena ʻia
ʻO kekahi o nā pono nui o ka polyurethane, hiki ke pena ʻia ma hope o ka hoʻōla ʻana.
Mahalo nā mea kākau hale i kēia no ka mea hiki i ka mea sila ke hoʻohālikelike pono i nā hoʻopau a puni me ka ʻole o nā laina hui i ʻike ʻia.
4. Kū'ē maikaʻi loa i ka abrasion
Nā hui kūkulu i hōʻike ʻia i:
• Kaʻahele Forklift
• Ka neʻe ʻana o ke kaʻa
• Ka lole hele wāwae
• Hoʻomaʻemaʻe mīkini
loaʻa ka pōmaikaʻi nui mai ke kūpaʻa ʻana o ka polyurethane.
5. Ikaika Mechanical Kiʻekiʻe
Hoʻohui nā mea hoʻopaʻa PU i ka maʻalahi me ka ikaika tensile kiʻekiʻe, e hiki ai iā lākou ke omo i ka neʻe ʻana me ka mālama ʻana i ka hoʻopili maikaʻi loa.
Nā noi kūpono no ka Polyurethane Sealant
Hoʻohana nui ʻia nā polyurethane sealant i nā hana:
• Nā hui hoʻonui sima
• Nā ala holo mokulele
• Nā Alanui Nui
• Nā hale kaʻa
• Nā hale kūʻai ʻoihana
• Nā panela sima i hana mua ʻia
• Nā hui hoʻohui o ka pā pale
• Nā hale kila
• Nā ʻōnaehana uhi
• Nā ipu hoʻouna
• ʻAhahui kino kaʻa
No nā noi hana kaumaha, e ʻimi i kā mākou Construction Polyurethane Sealant Solutions, i hoʻolālā ʻia no nā ʻoihana koʻikoʻi a me nā papahana ʻoihana.
He aha ka mea hoʻopaʻa silicone?
Mea hoʻopaʻa siliconehe elastomer hana kiʻekiʻe i hana ʻia mai nā polymers silicone. Ua kaulana ia no ke kūpaʻa kūikawā i ka radiation ultraviolet, ozone, ka makū, a me nā wela kiʻekiʻe.
ʻAʻole e like me ka polyurethane, noho paʻa loa ka silicone no nā makahiki he nui, ʻoiai ma nā wahi waho ʻino.ʻO kona kūpaʻa kemika e lilo ai ia i mea makemake nui ʻia no ka ʻenekinia façade a me nā ʻōnaehana glazing.
Nā Pōmaikaʻi Koʻikoʻi o ka Silicone Sealant
1. Kū'ē UV kūikawā
Kūpaʻa ka silicone i ka lā no ka manawa lōʻihi me ka ʻole o ka haki ʻana a i ʻole ka hōʻino nui ʻana.
2. Ka maikaʻi loa o ke aniau
Hana maikaʻi ʻo Silicone ma lalo o nā kūlana i lalo:
• Ua
• Hau
• Hau
• Haumākū kiʻekiʻe
• Nā wahi kahakai
• Nā aniau wao nahele
3. Ke kū'ē'ē mahana koʻikoʻi
ʻO ka mahana lawelawe maʻamau e kū mai ana ma kahi o:
• -50°C
• a i +150°C
ka hana ʻana i ka silicone i kūpono no nā aniau koʻikoʻi.
4. Hoʻōla Elastic Lōʻihi
Mālama ka silicone i ka elasticity ma hope o nā makahiki o ka neʻe ʻana o ka hui cyclic.
Ka Wehewehe ʻana i nā ʻokoʻa hana koʻikoʻi
1. Ka hiki ke pena (No ke aha e lanakila ai ʻo PU)
ʻO kekahi o nā hemahema nui o ka silicone ʻo ia ka hiki ʻole o ka pena ke pipili i kona ʻili.
Eia nō naʻe, ʻae ʻo Polyurethane i ka hapa nui:
• Nā pena acrylic
• Nā uhi wai
• Nā pena ʻaila
• Nā uhi ʻoihana
ʻO kēia ka mea e koho maopopo ai ʻo PU i ka wā e koʻikoʻi ai ke ʻano o ke kuhikuhipuʻuone.
Mea lanakila: Polyurethane

2. Ke kū'ē ʻana i ka ʻānai a me ka haehae
Hiki i ke kaumaha mechanical kaumaha ke komo koke i nā hui silicone maʻamau.
Hāʻawi ka Polyurethane i nā mea e pono ai:
• ʻOi aku ka paʻakikī o ka haehae
• ʻOi aku ka maikaʻi o ke kūpaʻa ʻana i ka ʻōpala
• Hoʻomaikaʻi ʻia ka hana hopena
e lilo ia i mea kūpono no ka papahele ʻoihana a me nā hui e hali ana i ke kaʻa.
Mea lanakila:Polyurethane

3. Hoʻopili ʻana i nā mea hoʻoheheʻe porous
Loaʻa i ka sima a me ka pōhaku nā pores microscopic.
Hoʻokomo pono ka Polyurethane i loko o kēia mau pores, e hana ana i ka hoʻopili mechanical a me ke kemika ikaika ma mua o ka silicone.
ʻO nā substrates maʻamau e komo pū me:
• Sima
• Piliki
• Pōhaku
• Paila
• Papa sima
Mea lanakila: Polyurethane

4. Ke kū'ē ʻana i ka UV
Hana kūikawā ʻia ka silicone no ka hoʻopili ʻana i ka lā no ka manawa lōʻihi.
Hana maikaʻi ka Polyurethane ma waho akā pono paha nā uhi pale i nā wahi me ka hōʻike ikaika ʻana o ka UV ma nā makahiki he nui.
Mea lanakila: Silicone

5. Ka Maluʻolu a me ka Neʻe ʻana o nā Hui
E loli mau ana nā mea hoʻopaʻa ʻelua.
Eia naʻe:
• ʻO ka silicone ma ke ʻano laulā e hāʻawi i ka elasticity lōʻihi.
• Hāʻawi ka Polyurethane i kahi kaulike maikaʻi ma waena o ka maʻalahi a me ka ikaika o ke kūkulu ʻana.
ʻO ke koho ʻana ma muli o ka hoʻoikaika ʻana o ka noi i ka ʻike ʻana i ke aniau a i ʻole ka hana mīkini.

6. Ka Pono o ke Kumukūʻai
Hāʻawi pinepine ka Polyurethane i kahi kumukūʻai haʻahaʻa no ke ola holoʻokoʻa no nā papahana ʻenekinia kīwila ma muli o:
• ʻOi aku ka maikaʻi o ke kūpaʻa ʻana i ka ʻaʻahu
• Hoʻopili ikaika
• ʻOi aku ka maʻalahi o ka pena hou ʻana
• Hoʻemi ʻia ka mālama ʻana ma nā wahi i nui ai ka poʻe hele
Hiki i ka Silicone ke hāʻawi i nā kumukūʻai mālama haʻahaʻa i nā noi glazing ma muli o kona kūpaʻa UV i kūlike ʻole.
