I te mea he tino iti te matotoru o te kapia wai-wai, kāore e taea te whakatutuki i ngā hiahia o te rokiroki me te hanganga o te paninga, nō reira me whakamahi i te whakamātotoru e tika ana hei whakatika i te matotoru o te paninga wai-wai ki te āhua tika.

He maha ngā momo whakamātotoru. I te wā e whiriwhiri ana i ngā whakamātotoru, me whai whakaaro ki ētahi atu āhuatanga hei hanga i te paninga kia pai rawa te mahi hanga, kia pai te āhua o te kiriata paninga, kia roa hoki te ora mahi.

Ko te kōwhiringa o te momo whakamātotoru ka whakawhirinaki nui ki te hiahia me te āhuatanga tuturu o te whakatakotoranga.

He mea nui ēnei i te wā e whiriwhiri ana, e whakamahi ana hoki i ngā whakamātotoru.

1. He nui ake te hononga o te HEC taumaha ngota teitei ki te taumaha ngota iti, ā, he nui ake te whai huatanga o te whakamātotoru i te wā e rongoa ana. Ā, ina piki ake te tere kutikuti, ka pakaru te āhua takai, ka nui ake te tere kutikuti, ka iti ake te pānga o te taumaha ngota ki te matotoru. Kāore he pānga o tēnei tikanga whakamātotoru ki te rauemi turanga, ngā tae me ngā tāpiringa e whakamahia ana, me whiriwhiri noa i te taumaha ngota tika o te cellulose me te whakarerekē i te kukū o te whakamātotoru ka whiwhi i te matotoru tika, ā, nō reira ka whakamahia whānuitia.

2. Ko te whakamātotoru HEUR he wairewa matotoru me te diol, te diol ether rānei hei whakarewa tahi, me te ihirangi totoka o te 20% ~ 40%. Ko te mahi a te whakarewa tahi he aukati i te piri, ki te kore ka noho ēnei whakamātotoru i roto i te āhua tiēre i te kukū kotahi. I te wa ano, mā te noho o te whakarewa ka ārai i te huka o te hua, engari me whakamahana i te takurua i mua i te whakamahinga.

3. He ngāwari te maka atu i ngā hua iti-totoka, iti-mātotoru, ā, ka taea te kawe me te penapena i roto i te rahinga. Nō reira, he rerekē te nui o te totoka o ētahi whakamaroke HEUR i roto i te hua kotahi. He teitei ake te nui o te whakarewa-tahi o ngā whakamaroke iti-mātotoru, ā, ka paku iti iho te matotoru waenga-kutikuti o te peita ina whakamahia, ka taea te whakakore i tēnei mā te whakaiti i te whakarewa-tahi i tāpirihia ki tētahi atu wāhi o te hanganga.

4. I raro i ngā āhuatanga whakaranu e tika ana, ka taea te tāpiri tika i te HEUR iti-matotoru ki ngā peita rapa. Mēnā ka whakamahia ngā hua matotoru teitei, me whakaranu te whakamātotoru ki te ranunga wai me te whakarewa-tahi i mua i te tāpiri. Mēnā ka tāpirihia he wai hei whakaranu tika i te whakamātotoru, ka whakaitihia te kukū o te whakarewa-tahi taketake i roto i te hua, ka whakanui ake i te piri, ka piki ake hoki te matotoru.

5. Me āta haere te tāpiri i te whakamātotoru ki te tāke whakaranu, ā, me whakatakoto ki te taha o te pakitara o te tāke. Kaua te tere o te tāpiri e tere rawa kia noho tonu te whakamātotoru ki te mata o te wai, engari me tōia ki roto i te wai ka hurihia ki raro huri noa i te rakau whakaoho, ki te kore, kāore e pai te whakaranu o te whakamātotoru, ka tino matotoru rawa rānei te whakamātotoru, ka pupuhi rānei nā te nui o te kukū o te wai.

6. Ka tāpirihia te whakamātotoru HEUR ki te tāke whakaranu peita i muri i ētahi atu wāhanga wai, ā, i mua i te whakamomona peita, kia tino kanapa ai.

7. Ka tāpirihia ngā whakamātotoru HASE ki te peita hei whakaehu i te hanga peita whakaehu, kāore he waimehatanga, he whakakorenga rānei i mua. Ka taea te tāpiri hei wāhanga whakamutunga i te wāhanga whakaranu, hei wāhanga horapa tae, hei wāhanga tuatahi rānei i te whakaranu.

8. Nā te mea he waikawa nui te HASE, mēnā he kawakore kei roto i te peita whakapūkara, ka whakataetae ia mō tēnei kawakore i muri i te tāpiri. Nō reira, me tāpiri mārire, mārire hoki te whakapūkara whakamaroke HASE, me te whakaoho kia pai, ki te kore, ka kore e pumau te pūnaha horapa o te tae, te here whakapūkara rānei, ā, ka whakau te mea whakamutunga e te rōpū mata kua whakakorea.

9. Ka taea te tāpiri i te kawakawa i mua atu, i muri rānei i te tāpiritanga o te matū whakamaroke. Ko te painga o te tāpiri i mua atu, kia kore ai e puta he kore pumau o te horapa o te tae, o te here emulsion rānei, nā te mea ka hopu te matū whakamaroke i te kawakawa mai i te mata o te tae, o te here rānei. Ko te painga o te tāpiri i te kawakawa i muri mai, ko te horapa pai o ngā matūriki whakamaroke i mua i te pupuhi, te rewa rānei i te kawakawa, ka ārai i te matotoru, i te kohikohi rānei o te rohe, i runga i te hanganga, ngā taputapu me te tukanga hanga. Ko te tikanga haumaru ko te waimeha i te matū whakamaroke HASE ki te wai i te tuatahi, kātahi ka whakakorea ki te kawakawa i mua.

10. Ka tīmata te pupuhi o te whakamātotoru HASE i te pH o te 6 pea, ā, ka tino whai hua te whakamātotoru i te pH o te 7 ki te 8. Mā te whakarerekē i te pH o te peita rapa ki runga ake i te 8 ka ārai i te hekenga o te pH o te peita rapa ki raro iho i te 8, ā, ka mau tonu te pumau o te matotoru.
