He rauemi hanga nui te Paura Latex Whakamarara Anō (RDP), ā, e whakamahia whānuitia ana i roto i ngā piripiri hanga, ngā rauemi pakitara, ngā rauemi papa me ētahi atu mara. Nā tōna kaha ki te whakamarara anō, te piri me te ngāwari, ka nui ngā painga i te wā o te hanganga.
1. Te whakarite i te emulsion
Ko te taahiraa tuatahi ki te hanga paura rapa ka taea te whakamarara anō ko te whakarite i te emulsion. Ko te tikanga o tēnei ka mahia mā te polymerization emulsion. Ko te polymerization emulsion he pūnaha āhua wai i hangaia mā te whakamarara ōrite i ngā monomers, ngā emulsifiers, ngā initiators me ētahi atu rauemi mata ki roto i te wai. I roto i te tukanga polymerization, ka polymerize ngā monomers i raro i te mahi a ngā initiators hei hanga mekameka polymer, ā, ka puta he emulsion pumau.
Ko ngā monomer e whakamahia whānuitia ana mō te whakapūhuitanga emulsion ko te ethylene, te acrylates, te styrene, me ētahi atu. I runga i ngā āhuatanga e hiahiatia ana, ka taea te whiriwhiri i ngā monomer rerekē mō te whakapūhuitanga copolymer. Hei tauira, ko te emulsion ethylene-vinyl acetate copolymer (EVA) e whakamahia whānuitia ana i roto i te whakarite i te paura rapa ka taea te whakamarara anō nā te mea he pai te ātete ki te wai me te piri.
2. Whakamaroke rehu
I muri i te whakaritenga o te emulsion, me huri hei paura rapa ka taea te whakamarara anō. Ko te tikanga ka tutukihia tēnei mahi mā te hangarau whakamaroke rehu. Ko te whakamaroke rehu he tikanga whakamaroke e huri tere ana i ngā rauemi wai hei paura.
I te wā e whakamarokehia ana te paura, ka whakakorikoria te wai kia rite ki ngā pata iti mā roto i te pūwero, ā, ka pā atu ki te hau wera wera. Ka tere te mimiti o te wai i roto i ngā pata, ā, ka whakapūpū te toenga o ngā matūriki hei paura ririki. Ko te mea nui ki te whakamaroke i te paura ko te whakahaere i te pāmahana me te wā whakamaroke kia rite te rahi o te paura rapa, kia nui hoki te whakamaroke, me te karo hoki i te pirau wera i puta mai i ngā pāmahana teitei.
3. Te maimoatanga mata
Hei whakapai ake i te mahi me te pumau o te paura rapa ka taea te whakamarara anō, ka rongoatia tōna mata. Ko te kaupapa matua o te maimoatanga mata he whakanui ake i te rere o te paura, te whakapai ake i tōna pumau rokiroki me te whakarei ake i tōna kaha ki te whakamarara anō i roto i te wai.
Ko ngā tikanga maimoatanga mata noa ko te tāpiri i ngā mea ārai-piki, ngā mea pani me ngā matū horoi. Ka taea e ngā mea ārai-piki te ārai i te pikinga o te paura i te wā e rongoa ana, me te pupuri i tōna rere pai; ko te tikanga ka whakamahia e ngā mea pani ētahi pūmua wairewa-wai hei pani i te paura rapa hei ārai i te urunga mai o te makuku; mā te tāpiri i ngā matū horoi ka taea te whakapai ake i te horapa anō o te paura rapa kia tere ai, kia ōrite ai te horapa i muri i te tāpiri wai.
4. Te tākai me te rokiroki
Ko te taahiraa whakamutunga o te tukanga whakaputa paura rapa ka taea te whakamarara ko te takai me te rokiroki. Hei whakarite i te kounga me te mahi a te hua, me aro nui ki te aukati i te makuku, te parahanga me te puehu kei rere i te wā o te tukanga takai. I te nuinga o te wā ka takaihia te paura rapa ka taea te whakamarara ki roto i ngā putea pepa maha-paparanga, i ngā putea kirihou rānei he pai te ātete ki te makuku, ā, ka whakanohoia he whakamaroke ki roto i te putea hei aukati i te makuku.
I te wā e rongoa ana, me whakanoho te paura rapa ka taea te whakamarara anō ki roto i te taiao maroke, e whai hau ana, kia matara atu i te rā tika me ngā taiao pāmahana tiketike, hei ārai i te hangai o te paura, te hekenga rānei o tana mahi.
He maha ngā mahi o te tukanga whakaputa paura rapa ka taea te whakamarara anō, pērā i te whakarite i te whakapūkara, te whakamaroke rehu, te maimoatanga mata, te takai me te rokiroki. Mā te whakahaere tika i ngā tawhā tukanga o ia hononga, ka taea te whakaputa paura rapa ka taea te whakamarara anō me te mahi tino pai me te kounga pumau hei whakatutuki i ngā hiahia rerekē o te umanga rauemi hanga. Mā te haere tonu o te whanaketanga o te hangarau, ka pai ake te taiao me te whai hua o te tukanga whakarite paura rapa ka taea te whakamarara anō a muri ake nei, ā, ka pai ake hoki te mahi a te hua.
