Ngā tikanga hanga
Tūnga Hākinakina
- 1. Te maimoatanga mata taketake: Tangohia te puehu, ngā paru hinu, ngā toenga tote, te waikura, me ngā mea tuku puehu mai i te mata o raro mā te tahia tuatahi, kātahi ka horoia. Kia oti te huri pai, ka mahia te kohikohi puehu mā te korehau.
- 2. Te paninga tuatahi motuhake: Tāpirihia te tuatahi motuhake mō te polyurea ki roto i te rōra hei hiri i ngā pūwero o te kiriuhi, hei whakaiti i ngā hapa o te paninga, hei whakanui ake i te piri i waenga i te paninga polyurea me te mata o raro.
- 3. Te whakapiripiri ki te putty polyurea (i runga i te āhua o te pakaru o te mata o raro): Whakamahia te rauemi whakapiripiri motuhake mō te polyurea hei whakatika me te whakataurite i te mata o raro. I muri i te whakamaroke, whakamahia he wira huri hiko hei oro pai, kātahi ka whakamahia he mīhini horoi korehau hei horoi.
- 4. Tāpirihia te paninga motuhake mō te polyurea ki te rōra: Katia anō te mata o te whenua, kia nui ake ai te piri i waenga i te polyurea me te turanga.
- 5. Rehuhia he paninga ātete wai polyurea: Whai muri i te whakamātautau i te rehu, rehuhia mai i runga ki raro, kātahi ki raro, me te neke haere i roto i tētahi wāhi iti me te tauira whakawhiti me te roa. Ko te matotoru o te paninga he 1.5-2mm. Ka oti te rehu i te kotahi te haere. Kei roto i "Ngā Whakatakotoranga Paninga Hangarau Polyurea" ngā tikanga motuhake. He mahi nui tāna ki te ārai wai, he ātete ki te kakahu, he ātete hoki ki te paheke.
- 6. Rehuhia/hurihia te paninga motuhake mō te polyurea: Whakaranua te matū matua me te matū whakamaroke kia ōrite te ōwehenga, whakaohokia kia pai, kātahi ka whakamahia te roera motuhake hei huri i te paninga polyurea ki runga i te mata paninga polyurea kua whakamaroke katoa. Ka ātete ki ngā hihi ultraviolet, ka ārai i te koroheketanga me te huringa tae.
Papa awheawhe
- 1. Te maimoatanga o te turanga: Hurihia te paparanga e mānu ana i runga i te turanga, kia kitea te mata o te turanga mārō. Me whakarite kia eke te turanga ki te taumata C25, neke atu rānei, kia papatahi, kia maroke, kia kore he puehu, ā, kia kaua e orohia anō. Mena he honikoma, he mata taratara, he kapiti, me ētahi atu, whakamahia ngā rauemi whakatika hei whakatika, hei whakataurite hoki kia mau tonu ai.
- 2. Te paninga o te paninga polyurea: Tāpirihia te paninga polyurea motuhake ki te turanga kia ōrite te hiri i ngā pūwero o te mata, kia pai ake te hanganga o te whenua, kia whakaitihia ngā hapa o te paninga i muri i te rehu, kia nui ake ai te piri i waenga i te putty polyurea me te papa sima, te papa raima. Taria kia maroke rawa i mua i te haere ki te taahiraa hanga e whai ake nei. Mena he nui te wāhi mā e kitea ana i muri i te paninga, me pania anō kia parauri pouri te papa katoa.
- 3. Te paninga o te putty polyurea: Tāpirihia te putty polyurea motuhake e ōrite ana ki runga i te turanga kia papatahi ai te papa, kia hiritia ngā pūwero e kore e kitea e te kanohi tahanga, ā, kia kore ai e puta he pūwero i te rehu o te polyurea nā ngā pūwero i runga i te papa. Taria kia maroke rawa i mua i te haere tonu ki te mahi hanga e whai ake nei.
- 4. Te paninga o te parai polyurea: Ki runga i te putty polyurea kua whakamaroketia, pania te parai polyurea kia ōrite te piri i waenga i te paparanga polyurea kua rehuhia me te putty polyurea.
- 5. Te rehu i te hanganga polyurea: I roto i ngā haora 24 i muri i te whakamaroketanga o te paninga, whakamahia ngā taputapu rehu ngaio hei rehu ōrite i te polyurea. Me maeneene te mata o te paninga, kāore he rerenga, he kōhao iti, he mirumiru, he ngatata rānei; mō ngā pakaru ā-rohe, ngā kōhao iti rānei, ka taea te whakamahi i te whakatikatika ā-ringa i te polyurea.
- 6. Te paninga o te paninga polyurea: Kia maroke te mata o te polyurea, pania te paninga polyurea hei ārai i te koroheketanga, te whakarerekētanga o te tae, me te whakapakari i te ātete kakahu o te paninga polyurea, hei tiaki i te paninga polyurea.
Ngā taputapu keri
- 1. Ko te papa whakarewa, ko te onepū hei tango i te waikura kua eke ki te paerewa SA2.5. Kāore he puehu parahanga, he paru hinu, me ētahi atu i runga i te mata. Ka mahia ngā maimoatanga rerekē i runga i te turanga.
- 2. Te rehu paninga (hei whakarei ake i te piri o te polyurea ki te turanga).
- 3. Hanganga rehu polyurea (te paparanga tiaki matua. Ko te matotoru e taunakihia ana kia waenga i te 2mm me te 5mm. Ka whakaratohia he mahere hanga motuhake e ai ki ngā hua e rite ana).
- 4. Hanganga paraihe/rehu o runga (ārai i te kōwhai, ātete ki te hihi UV, e whakanui ake ana i te whānuitanga o ngā tae e hiahiatia ana).
