Kua noho ko ngā papa vinyl me ngā hua PVC whakapaipai hei mea nui i roto i ngā whare hou, nā te mea he pakari, he maha ngā whakamahinga, he iti hoki te utu. Mai i ngā papa papa SPC (Stone Plastic Composite) ki ngā whakairo whakapaipai, ngā panera pakitara, me ngā whakapaipai taha, ka whakawhirinaki nui ēnei hua ki ngā tukanga whakairo werohanga tika hei whakatutuki i te kounga pumau. Kei te ngākau o tēnei tukanga tētahi wāhanga nui e warewarehia ana kia puta rā anō ngā raruraru: ngā whakaū PVC mō te werohanga.
Me whai taurite te whakahāngai werohanga o te PVC mō ngā papa me ngā mahi whakapaipai—me tu atu ngā rauemi ki ngā pāmahana tukatuka teitei (160–200℃) me te kore e pirau, me pupuri tonu te ataahua (tae ōrite, mata maeneene), me te tutuki i ngā paerewa taiao pakari. Mā te whiriwhiri i tētahi whakapūmau iti rawa ka arahi pea ki ngā hapa utu nui: te kōwhai o ngā papa, te "puawai" o te mata, ngā taha pakarukaru, tae noa ki te kati o te raina whakaputa. Ka whakamāramahia e tēnei tuhinga me pēhea te whiriwhiri, te whakamahi, me te arotau i ngā whakapūmau PVC mō te whakahāngai werohanga i roto ipapa winīrume ngā kaupapa whakapaipai, e whakaoti ana i ngā wero o te ao tūturu e pā ana ki ngā kaihanga me ngā kaiwhakawhanake hua.
He aha te take e hiahiatia ai he whakaū motuhake mō te whakakikoruatanga PVC mō ngā papa me ngā whakapaipai?
Nā te kore pumau o te PVC i raro i te wera me te kutikuti, kāore e taea te whiriwhiri i ngā mea whakau mō te hanga werohanga. Kāore i rite ki ngā tukanga whakaputa, ka pāngia te PVC e ngā pikinga tere o te pāmahana, te pēhanga teitei, me te wā noho poto i roto i te oko e te hanga werohanga—ngā āhuatanga e tere ake ai te tango i te waikura (te tukunga HCl) me te pakaru o te mekameka ngota. Mō ngā papa winira me ngā hua whakapaipai, he nui ake ngā tūponotanga:
AtaahuatikaMe rite te tae, te kanapa, me te maeneene o te mata o ngā papa me ngā whakapaipai. Ahakoa te iti o te tae, te puāwaitanga rānei, ka kore e taea te hokohoko.
Te ātete ā-mīhiniMe ātete te papa i te haere o te waewae, engari me ātete ngā whakairo whakapaipai ki te pānga. Ka pāngia te kaha rewa o te PVC e ngā mea whakau me ngā āhuatanga kume whakamutunga.
Te tutuki i ngā whakaritenga taiaoKo ngā ture ā-ao (EU REACH, US FDA) e aukati ana i ngā konganuku taumaha pēnei i te mata me te cadmium i roto i ngā hua kaihoko, e akiaki ana i te umanga ki ngā huarahi kē atu e pai ana ki te taiao.
Mō ngā wāhanga papa winiru i werohia ki te werohanga—pērā i ngā hononga honohono, ngā kōtaha taha, ngā tākai whakapaipai rānei—me ārai noa ngā whakaū i te pirau wera engari me whakarei ake hoki i te ngāwari o te tukatuka. Ki te kore e ōrite ngā whakaū, ka puta he raruraru pērā i te pakaru rewa, te putunga pokepokea ai, te kore ōrite rānei o ngā rahinga wāhanga—ka piki ake te tere o te para.
Te Whakatau i te NoaWhakapūmau PVCNgā Wero i roto i te Werohanga Molding
Ahakoa te momo whakaū tika, he maha ngā wā ka pāngia ngā kaihanga e ngā raruraru tono e whakararu ana i te kounga o te hua. Kei raro nei ngā otinga mahi hei whakatau i ngā raruraru e tino pāngia ana i roto i ngā papa winīra me ngā whakahāngai werohanga whakapaipai:
1. Te Pirautanga Wera (Te Kōwhai, Te Kakara Ahi)
RaruraruKa huri te taha o te papa, ngā whakapaipai rānei ki te kōwhai/parauri i te wā e hangaia ana; ka puta he kakara HCl kino i roto i ngā taputapu. Ka puta tēnei ina kore e taea e ngā mea whakau te whakakore i te HCl, te tu atu rānei i ngā pāmahana tukatuka.
Ngā TakeKāore i te rawaka te horopeta o te whakapūmau, he iti te kounga o ngā whakapūmau me ngā matū hohe ngoikore, he nui ake rānei ngā pāmahana tukatuka i te awhe o te whakapūmau. Mō ngā papa papa matotoru, ka nui ake te pirau i te mea ka nui ake te wera o te pokepokea ai.
Ngā otinga:
- Whakanuia te horopeta whakaū mā te 0.5–1 phr (ngā wāhanga mō ia rau kapia) mō ngā wāhanga matotoru-pakiwaitara; whakamahia ngā whakaū hiato hiato me ngā mea tautoko tahi (hei tauira, te hinu pīni soya kua whakapūkaratia) hei whakanui ake i te mahi wera.
- Whakaitihia te pāmahana o te oko mā te 5–10℃, ā, whakaitihia te tere o te tīwiri hei whakapoto i te wā noho.
- Huri ki tētahi mea whakaū Ca-Zn, tine waro rānei, he tino whai hua, kua whakamātauhia tana mahi i te 180–190℃.
2. Puawaitanga o te Mata (Hukapapa Mā)
RaruraruKa puta he kiriata paura mā ki runga i te mata o ngā papa, o ngā whakapaipai rānei i werohia, ka whakakino i te ataahua me te piri.
Ngā TakeHe ngoikore te hototahitanga i waenga i te whakapūmau me te kapia PVC, he nui rawa rānei ngā hinu whakahinuhinu taumaha-iti i roto i te tauira whakapūmau. He mea noa tēnei mō ngā whakapūmau Ca-Zn kounga-iti.
Ngā otinga– Kōwhiria he whakaū me ngā matūriki kua whakarerekētia te mata hei whakapai ake i te mararatanga o te PVC; karohia ngā whakaū he nui te ihirangi waikawa stearic.
- Horahia ngā whakau ki roto i tētahi puranga matua me te kapia PVC i mua i te whakahāngai kia ōrite ai te tohatoha.
- Whakaitihia te horopeta o ngā mea tautoko hei whakaū, ā, whakakapia ngā hinu whakahinuhinu iti te rewa ki ngā hinu whakakapi taumaha-ngota teitei ake.
3. Rere Rewa Kino (Whakakī Kāore i Oti, Pakaru Rewa)
RaruraruKāore i oti ngā hononga papa i werohia, ngā tauira whakapaipai rānei; he ngaru ngā mata, he koretake rānei te kakano nā te ngoikore o te kaha rewa.
Ngā TakeNgā mea whakau e whakanui ana i te matotoru rewa, te kore rānei e ranea te hinu whakahinuhinu i roto i te pūnaha whakau. Ko ngā mea whakau whenua onge ka tino pāngia e tēnei raruraru i ngā kawenga teitei.
Ngā otinga:
- Tīpakohia heWhakapūmau Ca-Znkua arotauhia kia rere—rapua ngā tātai me te rahi matūriki kua whakahaeretia me ngā whakaterenga whakakirihou.
- Tāpirihia he 0.3–0.5 phr o te hinu whakahinuhinu o waho (hei tauira, te ware pi polyethylene) hei whakapai ake i te rere o te rewa, me te kore e whakararu i te pumau.
- Whakatikatikahia te pāmahana o te pokepokea ai (whakapikihia mā te 10–15℃) hei whakaiti i te ātete rewa i te wā e whakakī ana.
4. Te Kore-Tutuki i ngā Ture
Raruraru: Kāore ngā hua e eke ki ngā whakamātautau konganuku taumaha (mata, cadmium) ka hipa rānei i ngā herenga hekenga mō ngā taonga pa-kai, ngā taonga whakapaipai rānei a ngā tamariki.
Ngā TakeTe whakamahi i ngā whakaū tote mata tawhito, i ngā whakaū Ca-Zn iti-kounga rānei kua poke i ngā konganuku taumaha.
Ngā otinga– Tangohia ngā whakaū mai i ngā kaiwhakarato me ngā tiwhikete tuatoru (REACH, FDA) e whakaū ana i te kore paitini.
- Whakatairangahia ngā whakatakotoranga Ca-Zn "kore konganuku taumaha"—ka whakaratohia e ngā kaihanga rongonui ngā pūrongo whakamātautau motuhake mō ia puranga.
- Kaua e whakaranua ngā momo whakaū; ka taea e ngā toenga taputapu kua poke i te mata te whakangaro i ngā puranga e tutuki ana i ngā whakaritenga.
Te Kōwhiri i ngā Whakapūmau PVC mō te Hanga Werohanga
Ehara i te mea he mahi matapae te whiriwhiri i te whakaū tika—engari me whakarite ngā whakaritenga hua, ngā tikanga tukatuka, me ngā whakaritenga ture. Whāia tēnei anga mō te whakatau māia:
Tautuhia ngā Kaupapa Matua o te Hua
Tīmata mā te tautuhi i ngā mea kāore e taea te whiriwhiri: Ataahua: Me hiahia koe ki te mārama (hei tauira, ngā panera whakapaipai) me te mā tonu rānei (ngā papa SPC)? Ko te tine waro, ko te Ca-Zn tino parakore rānei te mea pai rawa atu.
Taiao whakamahinga whakamutunga: Ka pāngia rānei te hua e te UV (whakapaipai o waho) e te kakahu kino rānei (papa)? He pai ake ngā mea whakau oneone, ngā mea whakau Ca-Zn whakarei ake i te UV rānei.
Ngā Ture: He rerekē ngā paerewa o ngā mākete ūnga (EU, US, Āhia)—me whakarite kia tutukihia i mua i te whakaritenga kia kore ai e mahi anō.
Whakatauritehia te Whakapūmau ki ngā Tikanga Tukatuka
Ko ngā tawhā whakapūmau werohanga e whakatau ana i te mahi a te whakapūmau: Pāmahana: Ko te whakapūmau pāmahana teitei (≥190℃) me whakamahi i te tine waro, i te Ca-Zn matatau rānei me ngā mea honohono.
Te wā huringa: Me whakamahi ngā matū whakaū me te whakakirikiri tere (hei tauira, te Ca-Zn iti-matotoru) mō ngā huringa tere kia kore ai e ngoikore te whakakirikiri.
Momo taputapu: Ka hiahiatia e ngā mīhini tīwiri-rua kutikuti-teitei he whakau me te marara pai hei ārai i te pirau kutikuti.
Whakamātautau mō te Hototahi me te Mahi
Kaua rawa e mahue te whakamātautau iti. Whakahaerehia ngā whakamātautau hei aromatawai i: Te pumau o te tukatuka: Tirohia mēnā he rerekē te tae, he putunga pokepokea ai, me te matotoru o te whakakī.
Ngā āhuatanga whakamutunga: Whakamātauria te kaha kume, te ātete pānga, me te kounga o te mata (kanapa, puāwai).
Te pakari mō te wā roa: Whakamātauria te pakeketanga wera (70℃ mō ngā hāora 72) kia mau tonu ai te tae me te kaha—he mea nui mō ngā papa.
Taurite Utu me te Uara
Ahakoa he pai ake te mahi a te tine waro, ka whakaitihia e ngā whakaū Ca-Zn ngā utu mā te 30–40% mō ngā hua kore-mārama. Tātaihia te tapeke o te utu o te mana pupuri: ka taea e te whakaū Ca-Zn he utu nui ake te whakaiti i ngā tere para (mā te whakaiti i ngā hapa) nui atu i te mea he iti te utu, he iti te mahi.
I roto i ngā papa vinyl me ngā whakahāngai werohanga whakapaipai, ehara i te mea he tāpiri mahi noa iho ngā whakapūmau PVC—he kaiārahi hoki i te kounga, te whai huatanga, me te tutuki i ngā whakaritenga. Ko te tapahi i ngā huarahi ki ngā whakapūmau ka hua ake he hapa utu nui me ngā mōrearea ture, ko te haumi ki te tauira tika ka whakanui ake i te pumau o te whakaputa me te roa o te hua.
Mā te whakatairanga i te hototahitanga ki ō tikanga tukatuka, te whakarite ki ngā paerewa ture, me te whakamātautau pakari, ka taea e koe te huri i te kōwhiringa whakaū hei painga whakataetae. Mō te nuinga o ngā tono, kua arotauhiaNgā whakaū hiato Ca-Zntuku i te taurite pai rawa atu—engari kaua e mangere ki te whakapai ake ki ngā kōwhiringa tine waro, ki ngā kōwhiringa oneone onge rānei mō ngā hua utu nui, motuhake rānei.
Kia maumahara: Ehara te whakaū pai rawa atu i te mea tino utu nui, i te mea tino rongonui rānei—engari ko te mea i whakaritea mō ngā hiahia motuhake o tō hua. Mā te huarahi tika, ka karohia e koe ngā hapa noa, ā, ka tukuna atu he papa winiru i werohia me ngā hua whakapaipai e tū motuhake ana i roto i te mākete kiki.
