Me pēhea te hanga kirihou Elastomer me ōna whakamahinga i roto i te umanga motuka
Pendahuluan
Ko ngā kirihou elastomer he rauemi he rite ngā āhuatanga pīngore ki te rapa, engari he painga anō kei roto i ngā pūhui kirihou. He tino whai hua ēnei rauemi i roto i ngā momo tono maha nā te mea he pakari, he ngāwari, he kaha hoki ki te hoki ki tōna āhua taketake i muri i te whakarerekētanga. Ko tētahi ahumahi kua tino whai hua mai i te noho mai o ngā kirihou elastomeric ko te ahumahi motuka. Ka whakamāramahia e tēnei tuhinga te hanga o ngā kirihou elastomeric me ō rātou whakamahinga i roto i te rāngai motuka.
Me pēhea te hanga kirihou Elastomer
1. Kōwhiringa Monomer
Ko te taahiraa tuatahi ki te hanga kirihou elastomeric ko te whiriwhiri i te monomer tika. Ko ngā monomer ngā ngota taketake e hono ana hei hanga i ngā polymer. Ko ngā monomer noa e whakamahia ana hei hanga kirihou elastomeric ko te butadiene, te isoprene, me te ethylene.
2. Tukanga Whakapūhui
I muri i te whiriwhiri i tētahi monomer, ko te taahiraa e whai ake nei ko te tukanga polymerization. He maha ngā tikanga polymerization ka taea te whakamahi, tae atu ki:
– Te Whakapūhuitanga o te Emulsion: Ka whakamararatia ngā monomers ki roto i te wai mā te whakamahi i tētahi emulsifier, kātahi ka tāpirihia he matū hei tīmata i te tauhohenga whakapūhuitanga.
– Te Whakapūhui Papatipu: Ka purea ngā Monomer kātahi ka tauhohe ki roto i tētahi tauhohenga nui.
– Te Whakapūhuitanga Otinga: Ka konatunatua te monomer ki te whakarewa me te kaiwhakaoho hei whakatutuki i te whakapūhuitanga.
Ka puta mai i te whakapūhui ngā mekameka pūhui roa mai i ngā monomer kua tīpakohia.
3. Te Huinga o ngā Tāpiringa
Kia oti te tukanga whakapūhui, ka taea te tāpiri i ngā momo tāpiri ki te pūhui hei whakapai ake i ōna āhuatanga. Kei roto i ēnei tāpiri:
– Kaiwhakaahua: Ka whakanui ake i te ngāwari me te ātaahua.
– Pūmau UV: Ka ārai i te pirau nā te hihi ultraviolet.
– Ngā Ārai Matewai: Ārai i te waikura ka kino pea ngā āhuatanga o te pūmua.
Tērā pea ka tāpirihia ētahi atu tāpiringa i runga i ngā whakaritenga whakamahinga whakamutunga o te elastomer.
4. Kaiwhakaōrite (Whakarei Hototahi)
Hei whakapai ake i ngā āhuatanga ā-pūkaha me te ā-wera, ka whakaranua ngā elastomers ki ētahi atu momo polymers. Ka whakamahia ngā compatibilizers hei whakarite kia pai te ranunga o ēnei rauemi e rua, ā, ka puta he hua me ngā āhuatanga pai rawa atu.
5. Te Tā me te Tukatuka Whakamutunga
Kia oti ngā kai katoa te whakaranu, ko te wāhanga whakamutunga ko te whakahāngai me te tukatuka. Ka rerekē pea tēnei tukanga i runga i te āhua me te rahi o te hua elastomer e hiahiatia ana. Ko ngā tikanga noa ko:
– Te Werohanga: Ka werohangahia te elastomer wai ki roto i te pokepokea ai, ka whakamataohia kia mārō ra ano.
– Te Whakaputa: Ka akiakihia te elastomer mā roto i te mata hei hanga i tētahi hua roa pērā i te paipa, i te rau rānei.
– Te Pupuhi Whakarewa: Ka hurihia te elastomer wai hei putea, hei pounamu, hei hua angiangi rānei mā te pupuhi i te hau ki roto i te pokepokea.
Ngā Whakamahinga o ngā Kirihou Elastomer i roto i te Ahumahi Aunoa
Ko te umanga motuka tētahi o ngā kaiwhakamahi nui rawa atu o ngā kirihou elastomeric mō ngā take maha. Anei ētahi o ngā whakamahinga o ngā kirihou elastomeric i tēnei rāngai:
1. Pūnaha Whakatārewatanga
Me whakamahi ngā pūnaha whakatārewatanga waka i ngā rauemi ka taea te mimiti i ngā wiri me ngā āwhatiwhati, kia pai ai te haere. He pai ngā kirihou elastomeric mō tēnei tono nā te mea ka taea e rātou te whakaiti i ngā wiri me te haruru e puta mai ana i ngā rori koretake.
2. Ngā Hiri me ngā Pakitara
Ka whakamahia ngā hiri me ngā gasket hei ārai i ngā turuturu wai me te hau i roto i ngā wāhanga miihini pēnei i ngā tuku me ngā pūnaha wahie. He maha ngā wā ka whakamahia ngā kirihou elastomeric hei hanga hiri me ngā gasket nā te mea he nui te ātete matū me te kaha ki te noho pīngore i raro i te whānuitanga o ngā pāmahana.
3. Te Hanga Tāia
Ahakoa kei te whakamahia whānuitia tonu te rapa maori i roto i te hanga potae, kei te piki haere te rongonui o ngā kirihou elastomeric nā te mea he ātete ki te kakahu me ngā āhuatanga pīngore. Mā te ranunga elastomer ka pakari ake ngā potae, ā, ka pai ake te mahi i roto i ngā momo āhuatanga huarere.
4. Te Hanga Taura me ngā Wāhanga Hiko
Me āta whakamarumaru ngā taura hiko me ngā wāhanga o ngā waka kia kore ai e poto te ara iahiko me te kino ki te taiao. E whakamahia ana ngā elastomers hei rauemi whakamarumaru nā te mea he tino ngāwari, he ātete hoki ki te kakahu me te tawhito.
5. Te roto o te waka
He maha ngā whakamahinga o ngā elastomers i roto i ngā roto o te waka hei hanga i ngā wāhanga pēnei i ngā papaaho whakahaere, ngā panera tatau, me ngā whakapaipai nohoanga. He pai te pā atu ki ēnei rauemi, he pakari, he ngāwari hoki te horoi, ā, he mea tino pai mō ngā momo whakamahinga o roto.
6. Pūnaha Tiaki
He maha ngā wā ka whakamahia ngā elastomers i roto i ngā pūnaha tiaki pēnei i ngā pare paru, ngā taupoki miihini, me ētahi atu wāhanga nā te mea he ātete ki te hinu, te wai, me ētahi atu matū. Ka āwhina tēnei ki te tiaki i te roto o te waka mai i te waikura me te kino.
7. Pūnaha Whakamatao me te Whakamahana
E whakamahia ana ngā elastomers i roto i ngā ngongo me ētahi atu wāhanga o ngā pūnaha whakamatao me te whakamahana waka nā te mea he ātete ki ngā pāmahana tino kino me ngā matū whakamatao. Mā ngā ngongo i hangaia mai i ngā elastomers ka pai te rere o te wai, ā, kāore e turuturu.
Whakamutunga
He tino ngāwari, he pakari hoki ngā kirihou elastomer, ā, kua huri i ngā āhuatanga maha o te umanga motuka. Ko tā rātou tukanga hanga he whiriwhiri tika i ngā rauemi me ngā tukanga tāpiri hei whakaputa i tētahi hua whakamutunga me ngā āhuatanga e hiahiatia ana. Nā tō rātou whakamahinga i roto i ngā pūnaha whakatārewatanga, ngā hiri, ngā gaskets, ngā potae, ngā taura, ngā roto o te waka, me ngā pūnaha tiaki, he mea tino nui rātou i roto i te umanga motuka.
E tūmanakohia ana ka whakarei ake te mahi a ngā kirihou elastomeric i roto i te umanga mā te haere tonu o ngā whanaketanga hangarau rauemi me ngā tukanga hanga. Mā te auahatanga tonu, e tūmanakohia ana ka hangaia e ngā kaihanga motuka he waka haumaru ake, he waka whakamarie ake, he waka whai hua ake hoki mā te whakamahi i tēnei rauemi whakamiharo.
