Te tūranga oka taea te whakamarara anōpūmuapaurai roto i te paura putty: he kaha te piri me ngā āhuatanga miihini, he tino ātete ki te wai, he uruhanga, he ātete ki te kawakore me te ātete ki te kakahu, ā, ka taea te whakapai ake i te pupuri wai me te whakanui ake i te wā tuwhera mō te roa ake.
1. Te pānga o te moata hou i konatunatua
1) Whakapai ake i te hanganga.
2) Te pupuri wai atu hei whakapai ake i te makuku o te sima.
3) Whakanuia te ngāwari o te mahi.
4) Āraia te pakaru wawe.
2. Te pānga o te whakapakeketanga o te moata
1) Whakaitihia te rerekētanga pīngore o te moata, ā, whakapiki ake i te hototahitanga ki te paparanga turanga.
2) Whakanuia te ngāwari me te ātete ki te pakaru.
3) Whakapai ake i te ātete ki te hinganga o te paura.
4) Kāore e pai mō te wai, e whakaiti rānei i te mimiti wai.
5) Whakanuia te piri ki te paparanga turanga.
Ka hangaia he emulsion polymer e te paura rapa ka taea te whakamarara anō ina pā ki te wai. I te wā e whakaranua ana, e whakamarokehia ana hoki, ka maroke anō te emulsion. Ka mahi te paura rapa i roto i te paura putty, ā, e whā ngā taahiraa e oti ai te tukanga hanganga pūnaha hiato o te whakamakuku sima me te hanganga kiriata paura rapa:
①Ina whakaranua te paura rapa ka taea te whakamarara anō ki te wai i roto i te paura putty, ka whakamararatia hei matūriki polymer pai;
②Ka āta hangaia te kirikiri sima mā te whakamakuku tuatahi o te sima, ka whakakīia te wāhanga wai ki te Ca(OH)2 i hangaia i te wā o te tukanga whakamakuku, ā, ka whakatakotoria ngā matūriki polymer i hangaia e te paura rapa ki runga i te mata o te kirikiri sima/te ranunga matūriki sima kāore i whakamakukuhia;
③ I te mea ka nui haere te makuku o te sima, ka heke te wai i roto i ngā pūwero o te uaua, ā, ka āta herea ngā matūriki polymer ki roto i ngā pūwero o te uaua, ka hanga he paparanga piri ki runga i te mata o te ranunga matūriki sima me te whakakī o te sima gel/sima kāore i te makuku;
④ I raro i te mahi a te tauhohenga wai, te mimiti o te paparanga turanga me te mimiti o te mata, ka whakaitihia te makuku, ā, ka whakakotahihia ngā paparanga whakarārangi kua hangaia hei kiriata angiangi, ā, ka honoa ngā hua tauhohenga wai hei hanga i tētahi hanganga whatunga katoa. Ko te pūnaha hiato i hangaia e te wai sima me te hanganga kiriata paura rapa ka whakapai ake i te ātete pakaru hihiri o te putty.
Mai i te tirohanga o te whakamahinga mahi, kaua te kaha o te putty e whakamahia ana hei paparanga whakawhiti i waenga i te whakamarumaru o waho me te paninga o te pakitara o waho e teitei ake i te moata parai, ki te kore ka ngawari te puta o te pakaru. I roto i te pūnaha whakamarumaru katoa, me teitei ake te ngāwari o te putty i te papa. Ma tenei, ka pai ake te urutau o te putty ki te huringa o te papa me te tiaki i tona ake huringa i raro i te mahi a nga ahuatanga taiao o waho, ka whakaiti i te kukū o te ahotea, ka whakaiti i te tupono o te pakaru me te tihore o te paninga.
