Piripiri Wera-rewa mō ngā Mahi Rakau WD8610
He piripiri polyurethane rewa wera kotahi te wāhanga o te WD8610, he totoka i te pāmahana rūma, ka huri hei wai i muri i te whakamahana, ā, ka hanga he hononga tuatahi i muri i te paninga me te here. Kātahi ka tino pai te piri, te ātete pāmahana, te ātete wai, te ātete hinu, me te ātete tawhito nā tōna kaha ki te whakamaroke me te hau me te makuku i runga i te mata o te rauemi kua herea.
E tutuki ana i te hua te rohenga o ngā matū waro pūngāwerewere i roto i ngā piripiri (GB33372-2020).
E whakamahia whānuitia ana te WD8610 mō te here i ngā papa rakau, ngā papa matotoru, ngā papa ātete ahi, ngā papa kirihou kōhatu, ngā papa kirihou rakau, ngā panera whakapaipai, te PVC, te ABS, te PMMA, te PC me ētahi atu papa me ngā kiriata nā te roa o te wā whakatuwheratanga.
1. Wāhanga kotahi, ngāwari ki te whakahaere, e tika ana mō te mahi mīhini, he tino pai te mahi.
2. He totoka te ihirangi o te 100%, kāore he parahanga, he hoa taiao.
3. He whānui te whakamahinga, he pai te piri ki ngā kirihou, te rakau, me ētahi atu.
4. He roa te wā whakatuwheratanga, he kaha tīmatanga teitei, he pai mō te herenga rohe nui.
5. I muri i te whakamaroketanga, he pai tōna ātete ki te pāmahana, ki te wai, ki te makariri, ā, he roa hoki.

Te tukatuka i mua
1. He paru hinu, he puehu te mata e piri ana, ā, ka pā ki te kaha o te piri, me horoi, me maroke, me kore hinu, me kore puehu rānei.
2. Mō ngā rauemi pēnei i te PP me te kaha mata kei raro iho i te 32 dyne, me whakamahi i te korona, i te mura rānei hei whakarite kia eke te uara dyne ki te 36, neke atu rānei.
3. Kaua te pāmahana o te mata o te rauemi piri i te wā e whakamahia ana e raro iho i te 20 ℃. Mēnā he iti rawa te pāmahana, ka poto te wā whakatuwheratanga, ka pā pea tēnei ki te wā mahi, ā, ka kore e pai te piri, ka motu rānei. Mēnā e tika ana kia herea te rauemi, me whakamahana.
Tikanga paninga
1. Ka whakamahia he tāke piri rewa hiri me te pūnaha piri rewa 20L/200L mō te tukanga piri rewa. Mēnā ka kitea he matotoru rerekē, he matūriki, he pahuka, he āhuatanga kē atu rānei i te wā o te tukanga piri rewa, whakapā atu ki ngā kaimahi hokohoko hangarau o Kangda tonu.
2. Ko ngā tikanga paninga ko te paninga hurihuri, te paninga waru, me te rehu i te pūwero tuitui.
Te wā whakamaroke
Ko te tukanga whakamaroke o WD8610 e whakawhirinaki ana ki ngā āhuatanga e whai ake nei:
1. Me whai taumata pāmahana me te haumākū motuhake te haumākū me te pāmahana o te taiao mō te whakamahinga me te whakamaroke kia taea ai te whakakotahitanga matū o te PUR. Nō reira, e taunakihia ana kia whakahaerehia te whakamaroke o te hua i raro i ngā āhuatanga pāmahana me te haumākū e tika ana. I te nuinga o te wā, e taunakihia ana kia kaua e iti iho te pāmahana i te 25 ℃, ā, kia kaua hoki e iti iho te haumākū i te 50% mō te whakamaroke mō te 1-7 rā.
2. Te haumākū i runga i te mata o te papa kua herea.
3. Te āheinga manawa o te papa kua herea.
4. Te horahanga piri/te matotoru o te paparanga piri i te wā e pania ana.
Tikanga horoi
1. Pūnaha kāpia rewa: Tuatahi, tātarihia te toenga o te kāpia mai i te pūnaha kāpia rewa, kātahi ka tāpirihia te kaihoko horoi WD8600 hei horoi rewa wera kia mimiti rawa te toenga o te kāpia rewa wera polyurethane.
2. Pūnaha whakapiripiri: Ka horoia te waru me te roera ki te wai horoi motuhake WD8602.
3. Mō ngā piripiri kua whakamaroketia, tēnā whakapā atu ki ngā tohunga hangarau o Kangda.
1. Me tāuta ngā taputapu whakaputa hau ā-rohe ki te wāhi mahi hei whakarite i te hauhautanga.

3. Nā te tauhohenga makuku o te hua, me āta tirohia te hiri o te takai i mua i te whakamahinga kia tino hiritia, kia mau tonu ai te kounga o te hua.
4. Pānuihia te pukapuka haumaru hua i mua i te whakamahinga.
Te pāmahana taiao: Penapena ki te rūma hauhautanga, maroke hoki i te 5-35 ℃.
Te roanga rokiroki i roto i te ipu hiri taketake: 9 marama.
