Te Ara ki te Whānui ake i te Ora o Tōu Mātātoko Injekihana Piraikete

Te Mārama ki te Ora Matomato o te Tā Mold Plastic me ngā Paerewa SPI Class

Ngā Haerenga Ora o te waainga SPI Class 101–105 me ngā taumata whanaketanga i te ao tuturu

E ai ki te Huinga o te Ahumahi Paraihe, e rima ngā momo rerekē o ngā mātā inihua e whakaaturia ana e te roa o tō rātou ora me ngā matapae e huri ana i te hanga i a rātou. Ko te tuatahi, te Karawhiti 101, e taea ana te nui ake i te miriona waea mā te kaha o ngā paraihe tapahi pērā i te H13, te S136 rānei. Kei te nuinga o ngā tūmau whakangao i ēnei wā, e hia tau pea ka hangaia ngā mea kia ū tonu, ā, ina koa kei ngā taputapu hauora me ngā taputapu e tino mau nei tātou i ēnei rā. Ki te heke ake i te arataki, e pai ana ngā mātā Karawhiti 102 mō te miriona waea, engari ka whakamahi i ngā matapae iti ake pērā i te P20, te 718 rānei. Ka tino mau ngā kaihanga i ēnei hei hanga i ngā wāhanga mō ngā motukā, nā te mea ka tuku ratou i te āhua pai i waenganui i te kaha me te utu. Kātahi ka tū karawhiti 103 e taea ana te haurua miriona waea me ngā mea pērā i te NAK80, te paraoa noa rānei, e kitea ana noa i ngā taputapu kei te kāinga. Mō ngā huinga iti ake i te 100k waea, ka tino whakamahi ngā tāngata i ngā mātā Karawhiti 104 e hangaia ana mai i te parāira. Arā anō, ko ngā tāngata e whakamātau ana i ngā hoahoa hou ka tīmata ki ngā tauira Karawhiti 105 e hangaia ana mai i ngā paraihe māpari, i ngā matapae hoki, e tino maroke ana i te iti ake i te 500 waea i mua i te hiahia ki te whakakapi.

Ko te mahi i te ao whai muri e heke iho ana 15–30% i raro i ngā tohu tāpiripiri SPI nō te āhua o ngā pūtau: he pai ake te marere o ngā harapeka kākahu pērā i ngā harapeka karaihe ki te karaihe, ā, he tere ake te warewarengatanga 40% i ngā arataki kāore i karaihe, ā, ko te whakahaere kore tōaitanga anō hoki e iti ake ai te roa o te ora.

Ngā āhuatanga matua e pā ana ki te kawe kaiwhakaahua porohita roa o te ora: hoahoa, matēria, tiaki, me te whakahaere tikanga

Ngā pou e whā e hāngai ana ki te roa o te ora angamaheni i te wā i tua atu i te whakarārangitanga SPI:

• Whakarite Hoahoa , tae atu ki te hoki makariri ā-hāwere, me te whakapapa ōrite, ka whakaiti i ngā takotoranga kikoheke e timata ana te mamae.
• Te Whiriwhiri I Ngā Kōwhiringa me whai mātai ki te āhuarangi rēhina—hei tauira, he mea nui te S136 e here ana i te pānga kia kore ai ngā toka karaiti tōtō i te PVC.
• Whakahaere Whakarato , pērā i te horoi me te whakapau manga kua takotoria, ka aukati i ngā toka iti kia kaua ai e tipu ki te porotiti o te hanganga.
• Te tāwhai tikanga tukanga , ina nui noa te pupuri i te wera paruru i roto i te ±5°C me te whakakore i ngā tāpene poto, ka whakarite tonu i ngā utu tana me te pūmahara wera.
  Ko te cawhitinga wera e kore nei e whakahaere ana anake e hua ana i te 68% o ngā porotiti māmā o ngā rama (Plastics Technology, 2023), e whakaatu nei i te āhua o te whakauru whakahaere paramita hei tiaki i te angaimahi—āno he mea anō kia ū te kounga matū ki ngā tīmatanga SPI.

Te hoahoa mō te Roa Ora: Ngā Whakaritenga Hanganga Matua mō ngā Rama Tā Injekihana Pāripi

Te whakapai ake i ngā punaha whakamaroke, whakaweto, me te tāpene kia mōhiotia ai te pānga wera me te hanganga

He nui te take o te whakarerea i ngā mea ki te wāhi tika mō te roa o ngā momo. Ina heke kāore ngā huringa o te mōmona i te tino, ka hua ngā raru. E ai ki ētahi rangahau pūkahukahu miramira mai i te tau ki muri, ko te heke kāore e tā ana i te haurua o ngā raruraru whakarereketanga, ā, he pai ake hoki te wareware i ngā wāhi e hangaia ana te toki. Ko te hoahoa tika o ngā ara hūkai e pupuri ana i te wāhi tike i roto i te rerekētanga o te 5 nekeneke Celsius i waenganui i ngā wāhi rerekē o te mōmona i ia mātātoko. Ka āwhina tēnei i te aukati i ērā itiiti arai ka hua ina heke kāore te wāhi tike. He mea nui anō te tāraiwa tika. Ngā punaha e tāmata ana ki te mahi, e 0.03 ki te 0.05 mirimita te rahi i ia tapakiromeita, e pupuri ana i ngā pōro pāpaku kia kaua e pakaru. Ka iti ake tēnei i te pēhanga tūpono ki roto i te karu mōmona e 30%, arā, he iti ake te toki ki ngā karu matua. A, ina tae mai te wā ki te wehe i te wāhi, kei te pai ake ngā papatipu tākarotia i te whakamahi anake i ngā karu. Ka tīmata tēnei i te kaha ki runga ki te hua o te hua, tētahi mea i whakaaturia kia iti ake te raru o te galling e toru hoki mā whā i ngā takotoranga hangarau motuka.

Ngā tikanga pai mō te hoahoa pātene, te āhuatanga o te āhua, me te tāraiwa o te toki

Ko te wāhi o te pātene e pā ana tino ki te āhuatanga o te rere me te tāraiwa o te toki. Ko ngā pātene tapa e pai ake ana i ngā pātene taha mō ngā wae tapa piri, e 22% te penapena i te maroritanga o ngā molekiula e hua ana i te tārai (Material Science Quarterly, 2024). Ko te āhuatanga o te āhua e toru ngā mātāpono matua:

• Ngā kōngā tāpae e hiahiatia ana he 1° ia 25 mm o te pōpara o te wae kia kore ai te tāpae e tōtō
• He iti rawa ngā pōpara o 0.5t (kei hea te = te tino pōpara o te matapae) ki ngā paparanga huinga kia māmā ai te toki
• Kua whakamātauria te āhuatanga o te core-cavity kia tōtō ki roto i te 0.02 mm e ngā mīhini ine takotoranga
  Ko te tāraiwa o te toki e hua ana i ngā rārangi takotoranga kua whakapai ai i te āhua, engari kāore i te tino rite o te pāpā, ka tārai anō i te uta māmā atu i ngā wāhi kātata, ka roa ake te wā o te whakamahi i ngā paerewa SPI.

Te whiriwhiri āhuatanga mō te roa ake o te mātai whakakī i te pāpā

Te whakarāpopotanga i ngā hiko toto matua (P20, H13, S136, 718, NAK80) mō te pakaru, te pā ki te pouri, me te pakaru mai i te wera

Ko te tira porowhita i whiriwhiria mō ngā rāwekenga he nui te pā ki te aronga o tā rātou mahi, ō rātou utu whakahaere, me te maha o ngā wā e hiahiatia ai te tiaki. Mō ngā kōrerorero iti i raro ake i te rima tekau mano karu, ka pai te P20 steel mai i te āhua moni, ahakoa kāore i pai ki te pouri. Ina heke te wāhi ki ngā pūnaha kawe wera, i te wā e hiahiatia ana te haurua miriona karu, ko H13 te kōwhiringa nui noa iho nā te matotoru me te āhua ki te whakamaori i ngā wera whakamuri. Ko S136 e takoto ana i ngā taiao e whakamahia ana ngā matapae pouri pērā i te PVC, engari me tino whai whakaarotia te maimoatanga wera kia pai ngā hua. Ko ngā kōwhiringa tikangia aha pērā i te 718 me te NAK80 e pupuri ana i te āhua hoki i ngā wera tikangia. Ina koa ko NAK80 e pupuri ana i tana tika ake ake ki te 300 degrees Celsius kaua ko ngā maimoatanga whakakaha atu, nā reira he pai rawa mō ngā wāhanga e hiahiatia ana ngā roa tata. Ka wehe pea ngā tira porowhita rerekē i runga i te wāhi i whakamahia ai. Ko S136 e tū ana ake i ngā wāhi kuwini e pakaru ana te matapae, ā, ko H13 e roa ake ana i ngā wāhanga kawe e pā ana te pēhanga wera. He mea hoki te tere o te tuku wera. Ko H13 e tuku wera atu ana i te 30% tere ake i te P20, e whakaae ana i ngā wā karu tere ake engari e hiahiatia ana he whakahaere tika ake i te wera i te tirohanga katoa.

Te whakauru i te matā o te mōhiotia ki te momo rēhina, ngā tāpiritenga, me te taiao whanonga (hei tauira, PVC, kī, nui ake te wai)

Ko te whakauru i ngā īnanga tika o te mātā tohatoha ki ngā tikanga tukatuka motuhake e aki ai i te pakaru koretake o te matēria i te wā o te hanga. Ina mahi ana me ngā polimeri kua kīia ki te kara, ka hiahia ki ngā mātā pūpahi kua pūharakeke. Hei tauira, ko te kiko 718 e mau ana i te wā roa ake i te 40% tata ki te mātā P20 tīmatanga ina whai kiko ana ki ngā matēria kōkirikiri, e nui ana te take i te wā roa. Me hiahia anō ki ngā kōwhiringa mātā kahurangi pērā i te S136 ngā rēhina kōhuruhuru pērā i te PVC kia taea ai te herekenga ki ngā raru piti me te whakarewa. Ahakoa i ngā taiao e kore nei he kōhuru te take matua, kei te parurenga i ngā wāhi whakaputa he mea tono anō i ngā kiko e āki ana ki te kōhuru. E taea ana e ngā tātai mata te āwhina i konei, engari e hāngai ana ki te utu tiaki ake i muri mai. Ko ngā rēhina hautarawhiti pērā i te polypropylene e pai ana ki ngā momo karapoti kaukauka kore-beryllium i roto i ēnei ara whakamaroke āhuatanga, engari kāore he hiahia ki ētahi mea hoki pēnei ngā matēria amorphic pērā i te ABS. Ko te noho o ngā taputapu whakamaroke ārai ahi he wero anō nā te mea e kātata ana ēnei ki ngā huinga kōpiri e arataki ana ki ngā raru pakaru kōkirikiri. Ko ngā karapoti pātiniti mātātini koiora e hiahiatia ana hei whakahaere i tēnei take. Ko te titiro ki ngā rahi o te whakaputa anō hoki e āhua ai te aha e tika ana ki te moni. Ka taea e te mātā P20 tīmatanga te mahi pai mō ngā haerenga takotoranga, engari ina kōrerotia ana ngā mātā e whakaputa haere ake i te haurua miriona, ka tika ake te utu atu moni mō ngā mātā taputapu kounga teitei pērā i te S7 ahakoa te utu tuatahi.

Ngā Tikanga Whakahaere ake e Hōhonu ai te Wā Pūmau o te Pepa Tāpiri Kōpae

Ngā mahi tiaki noa, paraire, me ngā wā poto mō te roa o te kōpae tāpiri kōpae

Ka taea e te whai i tētahi kaupapa tiaki tika te whakaroa i te wā ora o ngā rama mai i te 30 ki te 50 ōrau, mōrearea i te wā e tika ana mātou anake ki te whakatika i ngā mea ina hekeia ngā raru. Ka āwhina te tirohanga i ngā rama ia rā ki te kite i ngā raru i mua i te piki ake, pērā i ērā itiiti kapihi, i ngā hinga rānei e hangaia ana ki te mata. Kaua tekau mā whitu, he mea nui kia horoi i te paraihe parurenga katoa e noho ana kei ngā parirau, ngā ara whakamaroke, me ngā wāhanga nekeneke. Ka whakamahi mātou i ngā horoi māmā mō tēnei, nā te mea ka pirau ai ngā parirau me te tōaitanga o te wera i roto i te rama ngā mea uaua. I ia toru marama pea, ko te wehenga i te katoa e taea ai te tiro i ngā rahi tōaitanga, te maroke i ngā mata anō ki te paerewa, me te whakakī i ngā wāhanga e wareware ana tere, pērā i ērā pīni tūtāpui tawhito e pakanga ana. E ai ki ngā ine takehere mai i ngā kaihanga Tumu-1, ko ngā kaihanga e arataki ana i tēnei momo tikanga ka kitea e 42% te heke haere o ō rātou takotoranga mōrearea. He mea whai hua, nā te mea kāore he tangata e hiahia ana kia tū te hoko i te wā pōrite rawa.

Ngā hōtaka mātai, ngā tikanga horoi, me ngā rārangi whakamātautau kua whakamāoritia ki te hanga whenua Tiriti-1

Ko te mātai i ngā pou arataki me ngā takotoranga pokainga ia 5,000–8,000 mātai e aukati ana i te pararēhua o te metara-kī-te-metara—ka whakaatu ngā whakamātautau a te ahumahi mō te mātai tika ka iti ake ngā herenga e pā ana ki te pararēhua 68%. Ko te horoi puoroira he ara tūturu hei tango i ngā kirihou iti ake i te haurua-mikirona mai i ngā mata kakara e kore e taea e te hau totohu te tae atu. Ko ngā tikanga arotake kua whakamāoritia ko:

• Te whakapono i te tere o ngā awa whakamaroke (whakaroa ±5%)
• Te penapena takotoranga me te āhua karuwha trū whakamātau
• Ngā tirohanga i te rāwekenga o te papamōhiotia e whakamahia ana ngā ine pūmanawa 0.02 mm
  Ina honoa katoa, ka taea e ēnei tikanga kia eke ngā moma rama SPI Class 104 ki te 500,000 mātai nekehineke—āno he resin taraiwa kua waiho ki roto anō hoki.

Te whakapaipai i ngā Parāmata Tukanga hei Iti i te Wear Moma Ineiti Pāpaku

Te whakahaere mōrahi: te whakahaere i te paemata o te runga, paemata mata o te moma, me te mamae e hua ana i te mātai

Ko te tika o te whakahaere mōhio hikohepari e whai whakaaro ana ki te roa o ngā rama. Mā te pupuri i ngā kiko o ngā wae, inā koa kei roto i te rāwekenga o ngā wae pēnei i te 5 nekeneke Celsia anō, ka āki ai i ngā panonitanga mōrearea e kino ana ki ngā karu me ngā karuha i te roa o te wā. Ko te hoahoa o te punaha whakakī ano he mea nui anō. Ka pai ake ngā mahi i te wāhi ka makariri ngā rama i runga i ō rātou mata. Mō te makariri kore-taurite? E toru hauwhā pea o ngā herenga tūmataiti e hua mai ana i ēnei, e ai ki Plastics Technology i te tau ki muri. Āwhina ngā punaha e mōhio ana i ngā panonitanga o te kiko i waenganui i ngā waea kia maua ngā raruraru i mua i te wa e kino ai ki te tohu. Ā, titiro ki ngā nama: ko ngā rama e rere ana me ngā tikanga mōhio tūpato e here ana i te 40% iti ake te nuinga o te wā i ngā rama e kore nei e whakahaeretia tika.

Ngā tikanga matua / whakamutunga me te tautuhinga o te kaha pakipaki hei aronga i ngā kirihou iti me ngā korikori

Ko te tīmata āta i ngā mīhini mā te piki haere i ngā pāmahana whakahaere i roto i ngā huringa 15 ka āwhina ki te karo i te pāmahana wera e āhei ai te arahi ki aua kōpeke iti e hanga ana i roto i ngā rauemi. I te wā e kati ana i ngā taputapu, he mea nui kia tika te horoi i ngā pūnaha, kia āhei ai te whakawera kia kore ai e noho te raima i mahue, e puta ai te waikura ina kore e mahi. He nui hoki te nui o te taumaha o te pūāhua. Me noho te pēhanga ki roto i te 5% o te mea e hiahiatia ana e te raima motuhake. Mēnā he iti noa iho te heke, ka tīmata mātou ki te kite i ngā raruraru pēnei i ngā pakaru iti i puta mai i te whakaheke, i ngā take whakapataritari rānei i ngā rārangi wehe. Ko ēnei pūoko aunoa e tirotiro ana i te taumaha i mua i te whakahaere i ngā puranga nui he tino whai hua nā te mea ka kitea e rātau ngā raruraru iti o te whakatikatika e kore e kitea e te tangata i te wā o ngā tirotiro auau engari ka taea te arahi ki ngā pakaru nui ake ka tupu ake i te wā. E whakaatu ana ngā raraunga ahumahi e kotahi o ngā hapa pokepokea ai e whā e pā ana ki ngā kaha kōpeke hē i whakamahia i te wā o te hanga.
