ʻO ka pulupulu polyurethane ka mea hoʻoheheʻe polyurethane kiʻekiʻe.No ka mea, ka mea o kanā mea hoʻoheheʻe kiʻekiʻeua paʻi ʻia i loko o kahi keʻena huikau liʻiliʻi a milo ikaika i ka wikiwiki kiʻekiʻe, maikaʻi loa ka hui ʻana.ʻO ka mea e neʻe ana me ka wikiwiki kiʻekiʻe e hana i nā kulu noe maikaʻi ma ka nozzle o kapū puhia e pulupulu pono ia ma ka ili o ka mea.Hoʻohana nui ʻia ʻo Foamed polyurethane spraying no ka mālama ʻana i ka wela a me ka sila ʻana i ka mālama wela a me ka refrigeration.Hoʻohana ʻia ia no ka uhi ʻana i nā mea hoʻoheheʻe wela e like me nā pahu mālama spherical nui, nā paipu paipu kūikawā nui-diameter, a me nā paia mālama anu, a hiki ke hoʻomaopopo i ka hoʻoulu ʻana ma ka pūnaewele.
Nui nā pilikia i loaʻa i ka hana ʻana i ka polyurethane spraying, no laila he aha kēia mau pilikia?Pehea i hana ai kēia?
ʻO ka hapa nui kēia he pilikia hana, i wehewehe ʻia penei:
| Pilikia maʻamau | Ke kumu | Manaʻo |
| ʻO ka ʻili o ka ʻōhuʻa ʻala a me ka maʻamau | ʻAʻole maikaʻi ka atomization, ʻoi aku ka maʻamau me nā mea hoʻoheheʻe ea hui | Hiki ke hoʻololi kūpono i ke kaomi hope o ka ea compressor a me ka mamao mai ka papa kumu.Inā hiki, e hoʻolōʻihi a hoʻemi i ka nozzle hui ʻana o ka ea.Liʻiliʻi liʻiliʻi.Hiki ke mālama pono ʻia ka polyurethane sprayer kiʻekiʻe mai ka substrate. |
| ʻO ka wikiwiki ka manawa o ka huʻa a me ka viscosity o ka ʻeleʻele a me ke keʻokeʻo | ||
| He palupalu loa ka huʻa | Nui loa ka polyether | Manaʻo ʻia e hana i ka hoʻāʻo foaming manuahi ma ka ratio kūpono.Inā palupalu, hiki iā ʻoe ke hoʻonui i ka nui o ka isocyanate l kūpono.Inā palupalu, pono e nānā ʻia inā pono e hoʻohana ʻia ka ethylenediamine, e hoʻonui kūpono i nā mea maka i hoʻohana ʻia i ka mea keʻokeʻo. |
| ʻūhā ka ʻūhā
| Nui ka wai i loko o ka ʻōnaehana | Inā he palupalu wale ka ʻili, e noʻonoʻo inā ʻoi aku ka nui o ka ʻokoʻa ma waena o ka wela mea a me ka wela ambient, inā he kiʻekiʻe ka wela o ka mea, a haʻahaʻa ka wela o ka ambient.ʻO kekahi kumu ʻē aʻe he nui loa ka ʻokoʻa o ka viscosity ma waena o polyether a me Isocyanate a ʻoi aku ka isocyanate. |
| Nui loa ka ʻokoʻa viscosity ma waena o ka polyether a me Isocyanate | ||
| ʻO ka ikaika haʻahaʻa haʻahaʻa ma waena o ka foam a me ka substrate | ʻAʻole maʻemaʻe ka ʻili o ka substrate, me ka lepo e lana ana a i ʻole nā ʻaila ʻaila | ʻAʻohe komo ʻana o ka substrate, a ʻike ʻia ka makū ma ke kikowaena ma ka ʻili ʻana.Eia kekahi, he haʻahaʻa loa ka mahana o ka substrate, a wikiwiki loa ka wikiwiki o ka pua."Ke kāpīpī" ('o ia ho'i ka pipi'i 'ana i kahi papa ha'aha'a lahilahi), akā hiki i ka pulupulu mānoanoa ke ho'oulu i ka ha'alulu nui a me ka 'ili. |
| hāhā ʻōhū
| Ma muli o ka haʻahaʻa haʻahaʻa o ka lālā a me ka hana o ka polyether i hoʻohana ʻia i ka ʻōnaehana foaming | Hiki ke hoʻohui ʻia ʻo Sucrose, mannitol ma ke ʻano he polyether starter e like me ke kūpono.Eia kekahi, e hoʻonui pono i ka nui o nā papa e hoʻoheheʻe ʻia i ka wā o ke kūkulu ʻana i mea e pale aku ai i nā hanana hou |
| kaawale
| ʻOi aku ka wikiwiki a i ʻole ka lohi ʻana o ka manawa huʻa | E noʻonoʻo e hoʻomalu i ka wikiwiki o ka puaʻa |
| Hoʻohui ʻia ka ʻaila ʻaila silikoni he nui i ka ʻōnaehana huʻa |
