ʻO ka mea hoʻopaʻa hoʻopaʻa hoʻohui kūkulu Lejell223
Hōʻike huahana
ʻO Lejel-223 kahi mea hoʻoheheʻe polyurethane i hoʻopaʻa ʻia. Loaʻa iā ia ka hana hoʻopaʻa maikaʻi a me ka hoʻopaʻa ʻana. ʻAʻohe corrosion a me ka pollution i nā substrates, pili i ke kaiapuni, ʻaʻohe bula i ka wā o ka noi, ʻoluʻolu a maikaʻi hoʻi nā hiʻohiʻona
Eia kekahi, kūpaʻa loa kā mākou sealant i nā mea kūlohelohe e like me ka radiation UV, ka wela wela, a me nā kemika, e hōʻoiaʻiʻo ana i kona lōʻihi a me ka pono i nā kūlana paʻakikī. Hāʻawi ia i ka weatherproofing maikaʻi loa a pale i ka hoʻohaʻahaʻa ʻana o nā mea kūkulu hale, pēlā e hoʻonui ai i ke ola o nā hale. Eia hou, ua maʻalahi ka hoʻohana ʻana i kā mākou sealant, mālama i ka manawa a me nā koina hana i ka wā o ka hoʻokomo ʻana. Hoʻolaha kāna ʻano mea ʻawaʻawa i ka palekana no nā limahana a me nā mea noho, e hana ana ia i kahi koho kūpono no nā papahana e hoʻokumu ana i ke olakino a me ka hoʻomau. I ka hopena, ko mākou hale.
Nā wahi o ka noi
He kūpono no nā wahi kahi e pono ai ka neʻe haʻahaʻa, ke kūpaʻa kiʻekiʻe i ke komo ʻana a me ke kaomi. No ka hōʻoiaʻiʻo ʻana i ka wai o ke alo o ka ea ma nā alahaka, nā tunnels a me ka paipu hoʻoheheʻe wai.

Nā kikoʻī ʻē aʻe
ʻO Guangdong Pustar Adhesives & Sealants Co., Ltd. he mea hana ʻoihana o ka polyurethane sealant a hoʻopili i Kina. Hoʻohui ka hui i ka noiʻi ʻepekema, hana a kūʻai aku. ʻAʻole wale kāna kikowaena ʻenehana R&D ponoʻī, akā hui pū me nā kulanui he nui e kūkulu i kahi ʻōnaehana noiʻi noiʻi a me ka hoʻomohala ʻana.
Ua hoʻomaikaʻi nui ʻia ka poliurethane sealant "PUSTAR" nona ponoʻī e nā mea kūʻai aku no kona kūlana kūpaʻa a maikaʻi loa. I ka hapa lua o ka makahiki 2006, i ka pane ʻana i nā loli o ka noi mākeke, ua hoʻonui ka hui i ka laina hana ma Qingxi, Dongguan, a ua hōʻea ka pae hana makahiki ma mua o 10,000 tons.
No ka manawa lōʻihi, aia kahi kū'ē like ʻole ma waena o ka noiʻi ʻenehana a me ka hana ʻana i nā mea hana polyurethane sealing, kahi i kaupalena ʻia ai ka hoʻomohala ʻana o ka ʻoihana. ʻOiai i ka honua, hiki i nā hui liʻiliʻi ke hoʻokō i ka hana nui, akā ma muli o kā lākou Adhesive ikaika loa a me ka hoʻopaʻa ʻana i ka hana, ke hoʻonui mālie nei ka mana o ka mākeke, a ʻo ka hoʻomohala ʻana o ka polyurethane sealant a me nā mea hoʻopili i ʻoi aku ma mua o nā mea hoʻopaʻa silicone kahiko ke ʻano maʻamau. .
Ma hope o kēia ʻano, ua hoʻokumu ʻo Pustar Company i ke ʻano hana hana "anti-experiment" i ka hana noiʻi a me ka hoʻomohala lōʻihi, wehe i kahi ala hou i ka hana nui, hui pū me kahi hui kūʻai ʻoihana, a ua hoʻolaha ma nā wahi āpau. ʻāina a lawe ʻia aku i ʻAmelika Hui Pū ʻIa, Rusia a me Kanada. A ʻo ʻEulopa, kaulana ke kahua noi i ka hana kaʻa, kūkulu a me ka ʻoihana.
Hose sealant hoʻohana i nā ʻanuʻu
Nā ʻanuʻu kaʻina o ka hoʻonui ʻana i ka nui ʻana
E hoʻomākaukau i nā mea hana hana: ka pū hoʻopaʻa puʻupuʻu kūikawā nā mīkina lima pepa maikaʻi ʻo spatula knife Clear glue utility knife brush rubber tip scissors liner.
E hoʻomaʻemaʻe i ka ʻili o ke kumu lāʻau
E waiho i ka mea pale (polyethylene foam strip) e hōʻoia i ka hohonu o ka padding ma kahi o 1 knm mai ka paia.
Pepa i hoʻopili ʻia e pale i ka hoʻohaumia ʻana o nā ʻāpana hana ʻole
E ʻoki i ka nozzle me ka pahi
Eʻoki i ka puka sealant
I loko o ka nozzle glue a i loko o ka pū glue
Hoʻopili like ʻia ka sealant a hoʻokuʻu mau ʻia mai ka nozzle o ka pū glue. Pono e neʻe mālie ka pū kelu e hōʻoia i ka pili pono ʻana o ke kumu pipili me ka mea hoʻopaʻa a pale i nā ʻōhū a i ʻole nā lua mai ka neʻe wikiwiki loa.
E kau i ke kāpili maʻemaʻe i ka ʻōpala (maʻalahi e hoʻomaʻemaʻe ma hope) a hoʻololi i ka ʻili me ka ʻōpala ma mua o ka hoʻohana maloʻo.
Wehe i ka pepa
Hoʻohana ʻia nā ʻanuʻu o ka paipu paʻa paʻa
Poke i ka ʻōmole sila a ʻoki i ka nozzle me ke anawaena kūpono
E wehe i ka lalo o ka sealant e like me ke kini
E hoʻokuʻu i ka nozzle glue i loko o ka pū glue
