Hōʻike huahana
Inā ʻoe he ʻenehana kaʻa kaʻa a i ʻole ka mea nona ke kaʻa e nānā ana e hoʻoponopono i kou pale makani iā ʻoe iho, kūpono kā mākou polyurethane PU sealants no ka hōʻoia ʻana i kahi sila palekana a maikaʻi. ʻO kāna noi maʻalahi a me kāna hana hilinaʻi e lilo ia i mea hoʻohui waiwai i kekahi pahu hana mālama kaʻa.
Ma waho aʻe o nā pono kūpono, ua hoʻolālā ʻia kā mākou polyurethane sealants me ka ʻoluʻolu o ka mea hoʻohana. ʻO kāna kaʻina hana hoʻohana ʻoluʻolu e loaʻa i kahi sila maʻemaʻe, maikaʻi, mālama i ka manawa a me ka hoʻoikaika ʻana i nā hana hoʻoponopono makani.

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
