Kei roto i te mīhini whakaputa hau ngā wāhanga e whai ake nei: te pūwero, te tīwiri whāngai, ngā wāhanga whakamahana me te papu taputapu. Ka whāngaihia ngā rauemi ki roto i te mīhini i te pūwero. Ka nekehia ngā rauemi e te tīwiri whāngai e hurihuri tonu ana, e peia ana e te motuka me te pouaka miihini i roto i te oko me te mata. Ka pupuri ngā wāhanga whakamahana i te taha o te oko i ngā pāmahana kua whakahaeretia hei whakangawari me te whakarewa i te rauemi polymer. I muri i te putanga mai i te mata, ka tomo te rauemi rewa ki roto i te pokepokea ai me tētahi, neke atu rānei ngā kōhao, ka whakamatao, ka totoka ki te āhua e hiahiatia ana. I ētahi pūnaha, ka whakanohoia he papu taputapu ki waenganui i te oko me te mata hei whakarite i te pēhanga ōrite i roto i te rauemi e puta ana.

Te Whakaputa Polymer me te Werohanga Molding

Ngā Pūwāhi Ine Matotoru Matua i runga i te Mīhini Whakaputa

Putanga o te Hopper / Rohe Whāngai: Ka ine i te matotoru rewa tuatahi i te tīmatanga o te whakangawari o te pūmua.

Rohe Rewa (Waenganui-Pēra): Ka hopu i te whakawhiti ki te āhua rewa katoa.

Rohe Ine(I mua i te Papu Taputapu, i te Mate rānei): Ka ine i te matotoru o te rewa polymer i raro i ngā reiti kutikuti whakahaere.

Tomokanga Mate: E whakarato ana i ngā raraunga matotoru rewa i te wā tūturu i te pūwāhi o te whakaputanga.

Te Mārama ki te Rewa o te Polymer me te Matatini

He aha te whakarewa polymer?

He pūhui tēnei kua werahia kia rewa, e whakaatu ana i ngā āhuatanga rere e āhei ai te hanga mā te whakaputanga, te whakapūtanga rānei.te matotoru rewa o ngā pūmua—te ātete ki te rere—e whakawhirinaki ana ki te taumaha ngota, te pāmahana, te tere kutikuti, me ngā tāpiringa, e pā ana ki te kaha me te mutunga o te hua whakamutunga. I roto i tetukanga whakaputanga polymer, te wāhi e tukuna ai te pūmua rewa mā roto i te mate, ā, i roto i te whakahāngai werohanga, te wāhi e whakakī ana i ngā whakahāngai i raro i te pēhanga, me te pupuri i te kounga pai rawa atumatotoru rewahe mea nui. Tuku Ihote ine i te matotoru o te rewa o te polymerko ngā tikanga, pērā i te rheometry capillary kore-raina, he maha ngā wā ka whakaroa nā te mea ka whakaroa, ka akiaki i te nekehanga kiroto i te rārangimita viscometer mō ngā polymersmō ngā māramatanga wā-tūturu.

Ngā Wero i roto i te Whakaputa Polymer me te Whakahaere Tukanga

Tetukanga whakaputanga polymerā, he nui ngā arai e pā ana ki te hanga i te werohanga ki te pupuri i te pumau tonumatotoru rewa. Mā te rerekētanga nā ngā pikinga wera me ngā tere kutikuti e rerekē ana ka hua ake he kore tauritete matotoru rewa o ngā pūmua, e puta ai ngā hapa pēnei i ngā koretake o te mata, ngā āputa rānei i roto i ngā kōtaha kua whakapūtātia. Ka raru ngā raina whakapūtātanga nui ki te ōritete ine i te matotoru o te rewa o te polymerputa noa i te rere, me te pupuri i te tutuki i roto i te mana whakahaere tukanga. I roto i te hanga werohanga tere-rahi, ka kore e taea e ngā whakatikatika ā-ringa te pupuri i te tere o ngā wā huringa tere, ka tūpono ka piko, ka kore rānei e oti ngā whakakī. E whakaatu ana ēnei wero i te hiahia mō ngā mea matataumita waikeri polymerngā pūnaha, pērā i temita waikeri polymer aunoa, hei whakarato raraunga wā-tūturu, hei wikitoria hoki i ngā herenga o ngā tikanga tuku iho.

He aha te Hiranga o te Aroturuki i te Matatini Rewa

He mea nui te ine i te matotoru rewa i roto i te tukanga whakaputanga polymer me te hanga werohanga mō ētahi take. I roto i te whakaputanga, mā te matotoru rewa ōrite ka whakarite kia rite te whakakī o te mate, ā, ka ārai i ngā hapa pēnei i te koretake o te mata, te pupuhi rānei o te mate. I roto i te hanga werohanga, ka pā ki te whakakī o te pokepokea ai, te kounga o te wāhanga, me te wā huringa, ka taea e ngā rerekētanga te arahi ki te piko, ki te kore rānei e oti ngā whakakī. Mā te aroturukitanga wā-tūturu ka taea e ngā kaiwhakahaere te whakarerekē i te pāmahana, te pēhanga, te hanganga rauemi rānei i runga i te tere, me te arotau i te whakamahinga pūngao me te whakaiti i te para—ngā āwangawanga matua i te mea ka whakakaha ake ngā ture waro i te tau 2025.

Ko te uauatanga o te ine i te matotoru o te rewa polymer e ahu mai ana i te āhua kore-Newtonian o ngā rewa polymer, e rerekē ana te matotoru me te tere kutikuti me te hītori wera. Ka arohia tēnei e ngā pūnaha o ngā pūnaha ine matotoru polymer-rewa ā-roto mā te whakarato raraunga tonu, ka taea ai te whakahaere tukanga e kore e taea e ngā tikanga tuimotu te taurite.

Ngā Pātai Auau

He aha i nui ake ai te hiranga o te matotoru rewa i te pāmahana, i te pēhanga rānei?

Ka pā tika te matotoru o te rewa ki te rere o te rewa, te whakakī o te mate, me te ōritetanga o te hua, he nui ake te pānga o te pāmahana, te pēhanga rānei. Ko te ine tika i te matotoru o te rewa polymer ka ārai i ngā hapa pēnei i te piko, te pupuhi rānei o te mate, ā, he mea nui tēnei mō te whakahaere tukanga.

Me pēhea e whakarite ai a Lonnmeter i te whakaurunga raraunga?

Ka whakauruhia te mita waikeri polymer aunoa mā roto i ngā kawa 4-20mA, RS485 rānei, e tuku ana i ngā raraunga wā-tūturu ki ngā pūnaha whakahaere. Ko tana hītori kei roto i te pūnaha, e wātea ana mā te pūmanawa, e whakarato ana i ngā māramatanga hītori, e hipa ana i ngā herenga polymer mita waikeri tuku iho.

He aha ngā āhuatanga e pā ana ki te matotoru rewa o ngā polymer?

Ka pāngia te matotoru rewa o ngā pūmua e te taumaha ngota, te pāmahana, te tere kutikuti, me te aroaro o ngā tāpiringa, ngā whakakī rānei. Ko te taumaha ngota teitei me te pāmahana iti ka whakanui ake i te matotoru, ka pā ki te tukanga whakaputa pūmua.

Ko te aroturuki i te matotoru rewa he tūāpapa o te tukanga whakaputanga polymer me te whakahāngai werohanga, e whakarite ana i te kounga me te whai huatanga. Mā te tohungatanga kua whakamātauhia a Lonnmeter me te ine matotoru matatau mō ngā polymer, ka taea e ngā kaihanga te wikitoria i ngā wero i roto i te whakahaere tukanga me te arotau i te whakaputanga. Tonoa he utu i tēnei rā mai i tēnei kaiwhakarato ine matotoru polymer pono!
