Te Tukanga Whakaputa o te Paura Polymer Whakamarara Anō

He maha ngā wāhanga o te tukanga whakaputa paura pūmua ka taea te whakamarara (RPP), tae atu ki te whakapūmua, te whakamaroke rehu, me te tukatuka muri. Anei tētahi tirohanga whānui o te tukanga whakaputa noa:

1. Te whakapūhui:

Ka tīmata te tukanga mā te whakapūhui i ngā monomer hei whakaputa i tētahi marara pūhui, i tētahi emulsion rānei e pumau ana. Ko te kōwhiringa o ngā monomer e whakawhirinaki ana ki ngā āhuatanga me ngā whakamahinga e hiahiatia ana o te RPP. Ko ngā monomer noa ko te vinyl acetate, te ethylene, te butyl acrylate, me te methyl methacrylate.

1. Te Whakaritenga Monomer: Ka purea ngā Monomer, ka konatunatua ki te wai, ki ngā kaiwhakaoho, me ētahi atu tāpiringa i roto i te oko tauhohenga.
2. Whakapūhui: Ka pāngia te ranunga monomer e te whakapūhui i raro i ngā tikanga pāmahana, pēhanga, me te whakaohooho e whakahaeretia ana. Ka tīmatahia e ngā kaiwhakaoho te tauhohenga whakapūhui, ka hua ake ai te hanganga o ngā mekameka pūhui.
3. Whakapūmau: Ka tāpirihia ngā surfactants, ngā emulsifiers rānei, hei whakapūmau i te horapa o te polymer, hei ārai hoki i te totohu, i te kohikohi rānei o ngā matūriki polymer.

2. Whakamaroke Rehu:

I muri i te whakapūhuitanga, ka whakamaroketia te whakapūhuitanga o te pūhui kia huri hei paura maroke. Ko te whakamaroketanga o te pūhui ko te whakapūhuitanga o te whakapūhuitanga kia rite ki ngā pata iti, kātahi ka whakamaroketia ki te hau wera.

1. Whakakorikori: Ka pamuhia te horapa o te polymer ki te pūwero rehu, ka whakakorikorihia hei pata iti mā te whakamahi i te hau kōpeke, i te atomizer centrifugal rānei.
2. Te Whakamaroke: Ka whakaurua ngā pata ki roto i te rūma whakamaroke, ka pā atu ki te hau wera (ka whakamahanahia ki ngā pāmahana i waenga i te 150°C ki te 250°C). Ko te mimiti tere o te wai mai i ngā pata ka hua ake he matūriki totoka.
3. Kohikohinga Matūriki: Ka kohia ngā matūriki maroke mai i te rūma whakamaroke mā te whakamahi i ngā āwhiowhio, i ngā tātari putea rānei. Tērā pea ka whakarōpūhia ngā matūriki kikokore hei tango i ngā matūriki nunui rawa, kia ōrite ai te tohatoha o te rahi o te matūriki.

3. Tukatuka-muri:

I muri i te whakamaroke rehu, ka tukatukahia te RPP hei whakapai ake i ōna āhuatanga, hei whakarite hoki i te pumau o te hua.

1. Whakamatao: Ka whakamataohia te RPP maroke ki te pāmahana rūma hei ārai i te mimiti o te makuku, hei whakarite hoki i te pumau o te hua.
2. Tākai: Ka tākaihia te RPP kua whakamatao ki roto i ngā putea, i ngā ipu rānei ātete-makuku hei tiaki i te makuku me te haumākū.
3. Mana Whakahaere Kounga: Ka whakamatautauria te RPP hei manatoko i ōna āhuatanga ā-tinana me ā-matū, tae atu ki te rahi o te matūriki, te kiato papatipu, te nui o te makuku toenga, me te nui o te pūmua.
4. Te Rokiroki: Ka rongoatia te RPP kua tākaihia ki roto i tētahi taiao whakahaeretia kia mau tonu ai tōna pumau me tōna roa o te oranga tae noa ki te tukunga atu ki ngā kaihoko.

Whakatau:

Ko te tukanga whakaputa paura pūmua ka taea te whakamarara anō ko te whakakotahitanga o ngā monomer hei whakaputa i te whakamararatanga pūmua, ā, muri iho ka whakamarokehia te whakamararatanga hei huri i te whakamararatanga hei paura maroke. Mā ngā mahi tukatuka-muri ka whakarite i te kounga o te hua, te pumau, me te takai mō te rokiroki me te tohatoha. Mā tēnei tukanga ka taea te hanga i ngā RPP maha-mahi me te maha-mahi e whakamahia ana i roto i ngā momo ahumahi, tae atu ki te hanga, ngā peita me ngā paninga, ngā piripiri, me ngā kakahu.
