Painga o te Polyurethane Foam Caulking
1.High pai me te whakaora pūngao, kahore āputa i muri whakakī, me te hononga kaha i muri i whakaora.
2. He awangawanga me te pupuhi, kaore e pakaru, ka pirau, ka hinga ranei i muri i te rongoa.
3.With ultra-iti pāmahana kawe wera, ātete huarere me te tiaki wera.
4. Ko te tino pai o te whakamarumaru, te tangi oro, te parewai me te makuku-tohu i muri i te rongoa.
He aha te mea me aro ki te wa e hanga ana?
Ko te pāmahana whakamahi noa o te pahuka polyurethane ko +5 ~ + 40 ℃, me te pāmahana whakamahi pai ko +18 ~ + 25 ℃. I te mea he iti te pāmahana, ka tūtohuhia kia waiho ki te mahana o te +25 ki te +30 °C mo te 30 meneti i mua i te whakamahinga kia pai ai te mahi. Ko te awhe parenga pāmahana o te pahuka i rongoa he -35℃～+80℃.
Ko te pahuka polyurethane he makuku whakamaroke i te makuku, me rehu ki runga i nga mata maku ina whakamahia. Ko te teitei ake o te makuku, ka tere ake te rongoa. Ka taea te horoi i te pahuka kare i rongoa ki te horoi, ka tangohia te pahuka i rongoa ma te miihini (te kirikiri, te tapahi ranei). Ko te pahuka i rongoa ka huri kowhai ina pa ana ki te rama ultraviolet. E taunaki ana kia whakakakahuhia te mata o te pahuka i rongoa ki etahi atu mea (maata sima, peita, aha atu). I muri i te whakamahi i te pu rehu, me horoi tonu me te kaihoko horoi motuhake. I te wa e whakakapi ana i te taika rawa, ruia paitia te tank hou (kia 20 pea nga wa), tangohia te taika kau, ka tere te whakakapi i te taika rauemi hou kia kore ai e ora te hononga pu.
Ko te rerenga rere me te keu o te pu rehu e whakahaere ana i te nui o te rere pahuka. Katia te takirere rere ki te taha karaka ka mutu te rehu.
