He momo rauemi whakapaipai whare te pūti. Ko te paparanga pūti mā i runga i te mata o te rūma kau i hokona mai nei he nui ake i te 90 te mā, he nui ake i te 330 te pai. Ka wehea te pūti ki te pakitara o roto me te pakitara o waho. Me ātete te pūti pakitara o waho ki te hau me te rā, kia nui ai te kāpia, kia kaha ai, kia iti ai te taupū tiaki taiao. Ko te taupū whānui o te pūti pakitara o roto he pai, he hauora, he tiaki taiao hoki, kia kore ai te pakitara o roto e whakamahia ki waho, ā, kia kore ai te pakitara o waho e whakamahia ki roto. Ko te tikanga he gypsum, he sima rānei te pūti, kia taratara ai te mata, ā, he ngāwari ki te piri. Heoi, i te wā e hanga ana, me pania tonu he paparanga o te āpitihanga ki te papa turanga hei hiri i te papa turanga, hei whakapai ake i te piri o te pakitara, kia pai ake ai te piri o te pūti ki te mata turanga.
Ko te nui o te HPMC e whakamahia ana, e whakawhirinaki ana ki te āhuarangi o te taiao, te rerekētanga o te pāmahana, te kounga o te paura pungarehu konupūmā o te rohe, te tunu huna o te paura putty me "te kounga e hiahiatia ana e te kaiwhakahaere". I te nuinga o te wā, i waenga i te 4kg me te 5kg.
Ko te mahi a te HPMC he whakahinuhinu, ka taea ai te hanga i te paura putty kia pai te mahi. Kāore te Hydroxypropyl methylcellulose e whai wāhi ki tētahi tauhohenga matū, engari he āwhina anake. Ko te paura putty he momo tauhohenga matū i runga i te mata wai me te pakitara,
Ētahi raruraru:
1. Te tango paura o te putty
A: E pā ana tēnei ki te horopeta o te konupūmā raima, ā, e pā ana hoki ki te horopeta me te kounga o te cellulose, e whakaatuhia ana i roto i te tere pupuri wai o te hua. He iti te tere pupuri wai, ā, kāore i te rawaka te wā whakamakuku o te konupūmā raima.
2. Te tihore me te hurihuri i te paura putty
A: E pā ana tēnei ki te tere pupuri wai. He iti te matotoru o te cellulose, he mea ngāwari ki te puta, he iti rānei te horopeta.
3. Te mata o te ngira o te paura putty
E pā ana tēnei ki te cellulose, he ngoikore te āhua hanga kiriata. I taua wā anō, he paku tauhohenga ngā poke o te cellulose ki te konupūmā pungarehu. Mena he kaha te tauhohenga, ka whakaatuhia e te paura putty te āhua o te toenga tofu. Kāore e taea te piri ki te pakitara, ā, kāore he kaha here. Hei tāpiri, ka puta anō hoki tēnei i roto i ngā hua pēnei i ngā rōpū carboxy kua konatunatua ki te cellulose.
