Ko te kukume tahi i waenga i ngā wāhanga e pā ana o ngā matū rerekē e rua he whakaaturanga o te kaha ngota. Ka puta noa mai i te wā e tino tata ana ngā ngota o ngā matū e rua. Hei tauira, he piri i waenga i te peita me tePaipa DINSEN SMLe whakamahia ana. E pā ana ki te kaha o te mārō o te kiriata peita me te mata o te mea kua pania. Ka hangaia tēnei kaha here e te taunekeneke i waenga i ngā rōpū polar (pēnei i te hydroxyl, te carboxyl rānei) o te polymer i roto i te kiriata peita me ngā rōpū polar i runga i te mata o te mea kua pania.
Ka whakamahia e mātou i te nuinga o te wāte tikanga whatunga hei whakamātautau:
a. Kōwhiria he mata e tika ana, ka whakanoho ki tētahi tūranga pumau. Mō tētahi paparanga kiriata kāore e neke atu i te 50um te matotoru, tapahia te tohu i te tawhiti 1mm. Mō tētahi paparanga kiriata he 50um-125um te matotoru, tapahia te tohu i te tawhiti 2mm.
b. Tātaitia te tapawhā e hiahiatia ana i te ahunga poutū, ka whakamahi i te paraihe ngohengohe hei tango i ngā para kua wehea i runga i te paparanga kiriata.
c. Tirohia mēnā kua rakuraku te motu ki te pūtake. Ki te kore e uru ki te pūtake, me hanga anō he mata ki ētahi atu wāhi.
d. Tapahia he rīpene 3M, e 75mm te roa, ka whakapiri i tōna wāhanga waenganui ki te mata kua rakurakuhia, kia piri ōrite te rīpene ki te mata kua rakurakuhia, kātahi ka mirimiri ki te rapa kia piri pai ai.
e. Haea te rīpene i te 180° kia roa rawa te wā e taea ana i roto i te 90±30s.
f. Tirohia te paparanga kiriata kua tihorea mai i te papa whakarewa i roto i te wāhi whatu i raro i te karāhe whakanui.
