Ngā paninga wai-hāngai vs. ngā paninga whakarewa-hāngai

He maha ngā wā ka tangohia te ingoa o ngā paninga mai i te mea e herea ai, te kapia rānei, i hangaia ai. Ko ngā epoxies, alkyds me ngā urethanes he tauira katoa o ngā kapia e hoatu ana i te ingoa ki te paninga. Engari ehara i te mea koinei anake ngā wāhanga e hanga ana i te paninga. Haunga ngā tāpiringa, ka taea te hoatu i ētahi āhuatanga mahi ki te paninga, me ngā tae e hoatu ana i te tae, kei roto hoki i ngā paninga he huānga e whakarewa ana i te katoa ki roto i te wai kia ngāwari ai te tono.

Ko te tikanga, ko te wai, ko tētahi atu whakarewa matū rānei te āhua o tēnei matū whakawairakau. Nō reira te ingoa o ngā kupu "wai-e hangai ana" me te "whakarewa-e hangai ana". Ko te momo hua e tika ana mō te mahi ka whakawhirinaki ki ngā āhuatanga. I te nuinga o te wā, kāore tetahi e pai ake i tetahi, engari he rerekē te mahi i ngā āhuatanga rerekē. Ko te mea pai, ka noho tahi ngā kōwhiringa e rua i roto i ngā mahi a te tohunga paninga.

NGĀ PANIHANGA WAI-WHAKAMAHI

E ai ki te Paint Quality Institute, he whakahaere tohutohu me te whakamātautau peita, tata ki te 80 ōrau o ngā peita whare e hokona ana i ēnei rā, he peita wai. Kāore e kore ko tētahi o ngā tino take o ngā hua wai, ahakoa he peita whare o roto, he paninga tiaki taumaha rānei: he iti ake ngā kakara.

I te wā e mahi ana i roto i ngā wāhi kuiti, i ngā wāhi hauhautanga kore rānei, ka kore e pai te mimiti o ngā whakarewa mō ngā kaimahi, ka kino rānei ki tō rātou hauora. Nā konei, he maha ngā kaupapa pēnei i ngā tāke rokiroki wahie me ngā waka tāke tereina e whakamahi ana i ngā paninga wai. Ka whakaitihia hoki e ēnei te kukū o ngā rauemi mura e hangai ana i roto i te wāhi kuiti. Heoi, ehara i te mea ko te whakamahinga o ngā paninga wai ka whakakore i te hiahia mōNgā mahi haumaru mō ngā wāhi kuiti kua whakaaetia e te OSHA.

Ko te tutuki i ngā whakaritenga taiao tētahi atu take noa mō te whiriwhiri ki te whakamahi i tētahi paninga wai. He maha ngā whakarewa ka mimiti hei mea e mōhiotia ana ko ngā matū waro mimiti, arā, ko ngā VOC. He maha ngā kāwanatanga ā-motu, ā-rohe, me ā-rohe e whakahaere ana i ngā VOC mā te whakawhāiti i te nui o ngā pakihi e whakaaetia ana kia tukuna i roto i tētahi wā kua whakaritea. Ko teKa whakatakotohia e te EPA ngā ture ā-motumō ngā VOC, engari kua whakakaha ake anō ngā here a ētahi whenua, ā, me whakapau kaha ki te whakawhāiti i ā rātou tukunga.

Ahakoa rā, kāore e kore he whakarewa kei roto i ngā paninga wai. He maha kei roto ngā mea e kiia nei ko ngā whakarewa-tahi, arā, he iti ake te kukū o ngā whakarewa, ā, ko te tikanga he āwhina ki te pana i te toenga o te wai i waho o te paninga i a ia e maroke ana. Engari, nā te mea kāore he whakarewa o ngā paninga wai, he iti ake rānei, he huarahi pai ēnei hei whakaiti i te putanga VOC a te pakihi. Mō ētahi kamupene, ko te tikanga o tēnei he iti ake te whakapau moni ki ngā tohutohu mō te ture taiao. Mēnā rānei, kaua rātou e utu i ngā whiu nui mō te hipa i ngā whakaritenga VOC.

NGĀ PANINGA I RARO I TE WHAKAKORE

Ko ngā peita whakarewa he mea hanga mai i ngā matū wairewa ka mimiti mā te tauhohenga matū me te hāora. I te nuinga o te wā, mā te hau e neke ana e karapoti ana i te paninga whakarewa ka tere ake te tauhohenga, ka whakaiti i te wā maroke.

Kotahi te painga nui o ēnei paninga i ngā paninga wai. Kāore e pāngia e ngā āhuatanga taiao pēnei i te pāmahana me te haumākū i te wā e whakamaroke ana. Ka taea e te haumākū te aukati i te mimiti o te wai i roto i te paninga wai, ā, kāore e whai hua i ētahi āhuarangi.

He wero anō hoki ngā paninga wai-pūtake ki te wāhanga whakarite mata o tētahi kaupapa paninga. Ahakoa he whakakapi pai te wai mō ngā whakarewa i ētahi wā, he wāhanga matua anō hoki o te tukanga waikura, koinei te take katoa mō te umanga paninga ahumahi i te tuatahi. Mena ka pā te wai ki te papa i mua i te paninga, ka tīmata pea te waikura ira. Hei whakarite kia kore ai tēnei e tupu, me hanga ngā paninga wai-pūtake kia puta katoa te wai mā roto i te kiriata mata i mua i te waikura. Kāore tēnei e whakaarohia ana mō ngā paninga wai-pūtake.

Nō reira, hei whakarāpopototanga, ahakoa he kōwhiringa pai ngā paninga wai mō ngā mahi e pā ana ki ngā wāhi kuiti me te whakamahinga tonu o ngā paninga, kāore i te kore he ngoikoretanga. Ko ngā mahi i roto i ngā āhuatanga tuwhera, makuku, pērā i ngā mea e kitea pinepine ana i roto i ngā kaupapa paninga hanganga, ka taea tonu te whai hua mai i te paninga tika.
