Kōwhiringa rauemi tapanga

Me hangai te tapanga whaimana ki ngā āhuatanga o te mata me te piripiri, me te hoahoa āhua, te pai o te tā, me te pānga whakapiri hei whakahaere tukanga, ko te tono whakamutunga anake ka tino tika, ka whai mana te tapanga.

1. Te āhua o te tapanga

He aha te āhua o te tapanga e hiahiatia ana e koe?
Kāore he tae:mārama, mārama, tino mārama, tino mārama;
Mā: mā kanapa, mā ma, mā atarangi;
Ngā tae whakarewa: koura kanapa, koura matte, koura hiraka; hiriwa kanapa, hiriwa matte, hiriwa hiraka;
Taiaho: hologram, tauira taiaho.

He aha te tono me te āhua o te tapanga e hiahiatia ana e koe?
Tapanga ngongo ngohengohe: 370° te taupoki katoa (kua rahuitia te wāhi o te hinu kanapa hei taupoki) 350° te taha takoto kau;
Hiri: ka taea anake te hiri i muri i te whakapiri me te whakanoho ki te pāmahana rūma neke atu i te 23℃ mō te 24 haora i muri i te whakamaroke.

He aha te rahi o te tapanga?
Te pakari: te whakatau tika i te uauatanga me te kounga o te whakapiri; Te āhua me ngā āhuatanga o ngā mea whakapiri;
Matotoru: ka whakatau tika mēnā ka taea te whakapiri aunoa i te tapanga, ā, ka pā hoki ki te piko o te tapanga me tōna kounga.

2. Rauemi mata tapanga e tika ana mō te tā
Ko te rauemi piri-ā-ringa te kaikawe whakaahua me ngā mōhiohio, nō reira ko te whakaoti rapanga tānga rauemi te kaupapa matua a ngā kaiwhakarato rauemi. Ko ngā raruraru kounga o te kiriata piri-ā-ringa UV e whakaatahia ana i te waituhi maku me te maturuturu o te waituhi, ā, ko ngā take matua o ēnei raruraru ko ēnei āhuatanga:

Te taumata matatau o te kaiwhakahaere:He rerekē ngā momo rauemi, he rerekē te matotoru o te paparanga waituhi, ā, he rerekē ngā whakaritenga mō te waeine whakamaroke UV i runga i te mīhini tā. I runga i te mīhini tā, ka taea te whakarite i te kaha whakamaroke UV, te tere tā me te matotoru o te waituhi, pērā i te kore e taea e te kaiwhakahaere te whakahaere i te whanaungatanga i waenga i a rātou anō, ka pā ki te pānga whakamaroke UV, ka whakaata tika te pānga whakamaroke i te maturuturunga o te waituhi.

Kounga waituhi:Kei te piki haere te maha o ngā kaiwhakarato waituhi UV kei te mākete, kāore te kounga i te ōrite, ā, kāore te kaihanga kotahi i te ōrite te tere maroke me te tere whakamaroke o te waituhi tae rerekē. Nā te waituhi tonu i puta ai te āhuatanga mākū waituhi (ina koa te waituhi pango).

Rauemi:Ko ngā rauemi tā, ina koa ko ngā rauemi angiangi, ko tōna kukū mata te take matua e pā ana ki te mārō o te waituhi, engari mō ētahi rauemi (pērā i te BOPP, PP, PET) ka whakawhirinaki noa ki te kukū mata korona, kāore e taea te whakatutuki i ngā whakaritenga o te tā waituhi UV.

3. Te āhuatanga o ngā mea whakapiri
Ka pā nui ngā āhuatanga rerekē o ngā mea whakapiri ki te whakapiringa whakamutunga o te tapanga. He rerekē ngā whakaritenga mō te piripiri i ia āhuatanga.

Mena he iti te kaha o te mata, pērā i te HDPE, LDPE, PP, me ētahi atu, me whakamahi te kāpia me te kaha piri kaha.

Hei tauira, ka whakapirihia ngā pounamu PET me ngā putea PVC he nui ake te kaha o te mata, nā te mea he rerekē te āhua o ngā mea whakapiri, me ārai i te piri kia noho ki runga i ngā mea whakapiri, nō reira me whiriwhiri te piripiri he kaha ake te piri.

Ahakoa he mea whakakirihou, he nui rawa rānei te mea tango huruhuru i runga i te mata o te mea whakapiri, ka pā ki te kaha o te piri.

Ko ngā mata taratara o ngā mea whakapiri, pērā i ngā pounamu ngohengohe, te kakahu kore-whatu, te mata taratara o ngā pounamu PP me te PE, me whai piripiri ngāwari ake.

4. Te āhua o te pewa o ngā mea whakapiri
Me papatahi te mata tapanga o ngā mea whakapiri ina whakatuwheratia. Mena he piko ngā mata tapanga e rua (he mata tapanga porowhita) i muri i te whakawhanuitanga o te mata tapanga, kāore e taea te whakapiri pai i te ūnga tapanga. Nō reira, me hoahoa te tinana o te pounamu kia kore ai e whakamahia he āhua koretake.

I muri i te tango i te āhua o te mata tapanga porowhita, ka nui ake te rahi o te radian, ka teitei ake ngā whakaritenga mō te ngawari o te rauemi. Ko te ngawari me te pakari he takirua o ngā tikanga whakapuakitanga e rite ana.
