Mā ngā inenga matū ahumahi mō te ine i te paru ka whakarite kia ōrite ngā āhuatanga polyoxymethylene acetal, e tautoko ana i te kaha miihini me te pumau wera i roto i ngā tono kirihou acetal. Teitei te tikangā mita mātotoru paruka whakaitihia hoki ngā utu rauemi mā te arotau i te horopeta, e ai ki ngā pūrongo ahumahi e whakaatu ana i ngā penapena 7–9% mō ia puranga. Ka whakaitihia e te aroturukitanga kiato tukanga ipurangi te whakahaere ā-ringa, ka whakaitihia te wā whakatā mahi tae atu ki te 20%.
Mā ngā mita matatau o te whakahaere tukanga ahumahi e whakarato he urupare matua mō ngā whakaranu parai acetal, e aunoa ai ngā whakarerekētanga i te wā o te tukanga whakaranu. Ko te hua o tēnei he kaha ake ngā ātete tukanga me te iti ake o ngā puranga kāore i te tino hiahiatia, e whakanui ana i te putanga me te whai huatanga o ngā rauemi.

Kupu Whakataki
Ko te ine i te mātotoru me te kukū ā-roto e pupuri ana i te mana whakahaere tino pakari o te ranunga paru acetal. Ka tukuna e ngā mita mātotoru paru tino tika ngā raraunga wā-tūturu mō ia puranga polyoxymethylene acetal. Mā te ine ine densitome ahumahi mō te ine paru ka whakarite kia rite te horapa o ngā matūriki me te ōritetanga o te otinga. Ka ārai ngā tikanga ine i te mātotoru tukanga i te kohikohinga me te āhei i te whakatikatika tika i roto i te whakamahinga o te whakaranu paru acetal. Mā te whakamahi i ngā mita mātotoru whakahaere tukanga ahumahi ka āhei te aroturuki aunoa i te mātotoru tukanga ipurangi me te tata kore e wawao ā-ringa. Ka tautokohia e ngā tono mita mātotoru marau whakahāngai te whakatikatika tika o ngā reiti whāngai, te whakahekenga rānei, ka tapahia te rerekētanga o te hua. Ka inehia e ngā taputapu ā-roto mai i Lonnmeter te mātotoru me te kukū, ka tautoko i ngā tono kirihou acetal katoa, ka tutuki i ngā whakaritenga hua me te kounga. Ka whakaitihia e ngā tikanga ine i te mātotoru paru ngā ngaronga rauemi mata, te para, me te wā kore mahi e puta mai ana i ngā ranunga hē.
He Tirohanga Whānui mō te Tukatuka Parai Acetal
Ka tukatukahia te acetal polyoxymethylene (POM) hei para wai mō te hanga motuka, hikohiko, me te matū. Nā te pakari teitei o te POM (te modulus kume ~ 2.8 GPa), te tauwehenga waku iti (~0.2), me te mātotoru (1.41–1.43 g/cm³) ka taea te whakaranu tika, pumau te rahi i raro i te whakaoho. Ka mau tonu te tohatoha matūriki ōrite i te ranunga para hei tautoko i ngā tono kirihou acetal kounga teitei me te whakaiti i te kakahu i te wā e tukatukahia ana.
Ko ngā mita mātotoru ahumahi, pērā i ngā mita mātotoru ā-roto me ngā mita mātotoru ahumahi mō te ine i te paru, ka tukuna he pānui tino tika i te wā tūturu. Mā te aroturuki i te mātotoru tukanga ipurangi ka tere te urupare ki ngā rerekētanga mātotoru, ka tautoko i te whakahaere tukanga mā ngā whakaranu paru acetal me te whakaiti i te mōrearea whakahiato. Mā te aroturuki tonu mā ngā mita mātotoru paru tino tika ka ārai i ngā rerekētanga e hua ai ngā ranunga kore-taurite, ngā hapa, me te whakamahinga nui o ngā rauemi mata. Mā ngā tono mita mātotoru marau whakahāngai ka whakarei ake i te whakahaere i roto i ngā tukanga tonu me ngā tukanga puranga, ka mea he mea nui ēnei mita mātotoru whakahaere tukanga ahumahi mō te arotau i te ine mātotoru paru acetal puta noa i te whakaputanga.

Ngā Wero i roto i te Ine i te Kiato/Te Kukū ā-Rārangi
Ko te whakakotahitanga i roto i te paru acetal ka hua ake te paru o te pūoko me te tohatoha matapōkere, ka whakapēhia ngā pānui mai i ngā mita kiato ahumahi tae atu ki te 8%. Ko ngā rerekētanga o te matotoru me ngā rahi matūriki rerekē ka whakarerekē i te wā urupare me te tika i roto i ngā tono mita kiato marau whakahāngai, ka uaua ake te whakatikatika me te whakahaere wā-tūturu. Ko ngā huringa pāmahana tere—±3°C nekehanga—ka pā ki te kiato paru tae atu ki te 1.2%, ka whakawehi i te pumau i roto i te aroturuki kiato tukanga ipurangi. Ka puta mai i te tauira ā-ringa ngā whakaroa raraunga tae atu ki te 7 meneti me te whakaaro kino o te kaiwhakahaere, ka whakararu i te ine kiato paru tino tika. Ko te kore hototahi o ngā rauemi pūoko ki ngā āhuatanga polyoxymethylene acetal ka taea te whakaoho i te pupuhi o te mata, ka puta he nekehanga i roto i te densitometer ahumahi mō te ine paru. Me whakarato e ngā mita kiato whakahaere tukanga ahumahi he mahi pakari ahakoa ngā hapa o te whakamahinga o te whakaranu paru acetal, te aukati i ngā pānui hē me te arotau i ngā tono kirihou acetal. He mea nui te piripono ki ngā tikanga ine kiato paru tika hei whakarite i te mahi tonu me te pono.
Ngā Painga o te Whakauru i ngā Mita Kukū/Rārangi-ā-roto
Mā ngā mita mātotoru ā-roto ka taea te whakatikatika tonu i te hanganga o te paru acetal mā te whakarato i te ine i te mātotoru tukanga tūturu, tonu. Ka tukuna e ngā tono mita mātotoru marau whakahāngai he urupare tere mō te whakatikatika i te mātotoru paru, te whakaiti i te whakamahinga rauemi mata nui me te aukati i ngā puranga kore-tautuhi. Ka mau tonu ngā mita mātotoru paru tino tika i ngā āhuatanga polyoxymethylene acetal i te wā whakaranu, kia rite ai te tohatoha matūriki me te whakapai ake i te ōritetanga hua. Ka aunoa te mana whakahaere a te densitometer ahumahi mō te ine paru, ka whakaiti i te wawaotanga ā-ringa a te kaiwhakahaere me ngā hapa tauira, ka hua ake he raina whakaputa kua māmā ake. Ka taea te whakawhanui i ngā otinga mita mātotoru ā-roto a Lonnmeter, ā, ka urutau ki ngā tono kirihou acetal rerekē, e tautoko ana i ngā whakaritenga hanga rerekē. Ka whakanui ake te aroturuki i te mātotoru tukanga ipurangi hou i te tere o te mahi, ka whakakore i ngā whakaroa tukanga, ka whakaiti i ngā utu whakahaere e pā ana ki ngā tirotiro kounga ā-ringa. Ko ngā mita mātotoru whakahaere tukanga ahumahi i hangaia mō ngā paru whakakoi me iti ake te tiaki i ngā taputapu tuku iho, me ngā rauemi pakari i hangaia hei tu atu i ngā taiao paru kaha me ngā huringa pāmahana auau.
Whakauruhia ngā taputapu Lonnmeter mō te whakahaere tika i te whakamahinga o te ranunga parai acetal, te aroturuki i te kiato tukanga ipurangi, me ngā mita kaha mō te whakahaere i te kiato tukanga ahumahi puta noa i ngā tono kirihou acetal rerekē. Tonoa he utu inaianei tonu.
