He whānui te whakamahinga o te karāhe i ēnei rā, ā, he hua tonu tēnei e tino hiahiatia ana e te mākete. Mā te whakamahi i ngā tikanga maimoatanga motuhake, kāore e taea e tātou te aro nui ki ngā āhuatanga o te karāhe anake, engari ka taea hoki e tātou te whakatika i ōna ngoikoretanga, kāore nei e pāngia e ngā āhuatanga tūturu o te karāhe. Hei tauira, kāore e taea e te karāhe whakakikoruatia te whakamahana i te whakamarumaru anake, engari kāore hoki e pupuhi ngā kongakonga e whara i te tangata, he mea haumaru, he mea pono hoki. Muri iho, ko tātou heikaiwhakarato pounamu waika whakaatu i ngā painga o te arai karāhe mōngā thermosme te tikanga whakaputa o te arai karāhe.
二. Painga oarai karāhe mō te thermos
1. Mō te haumaru, he maha ngā wāhanga ka tauhohe kingā ipu whakarewa pērā i te kowiri tira i te pāmahana teitei hei whakaputa i ngā matū kino ki te tinana; Ina koa mō te rongoā Hainamana tuku iho kua kohuatia, kaua e ringihia te hupa rongoā ki roto i te ipu whakarewa, nā te mea ka tauhohe ngā wāhanga whai hua o te wai rongoā ki te whakarewa, ā, ka puta he urupare kino.
2. Mō te utu, ki te whakaritea ki te utu o te kowiri tira, ki ētahi atu rauemi rānei, he iti ake te utu o te arai karāhe;
3. Mō te pānga o te whakamarumaru wera,arai karāhe korehauhe tino paiārai wera pānga i waenga i ngā momo raina, ā, he nui te utu; Koinei te take i whakamahia tonutia ai ngā raina karāhe i roto i ngā wāhi werangā pounamu waii te kāinga;
4. Te tiaki taiao, te akuaku me te horoi ngāwari;
He aha te hanga o te arai karāhe o te ipu thermos?
① Te whakarite i te pounamu kore-para. Ko te rauemi karāhe e whakamahia ana mō ngā thermos nō te karāhe silicate konutai konupūmā e whakamahia whānuitia ana. Tangohia te wai karāhe pāmahana teitei, kāore he poke, ka pupuhi ki roto.pounamu karāhe o rotohe pounamu pātea me te pounamu o waho he pātea me te matotoru o te pakitara o te 1 ~ 2mm i roto i te pokepokea whakarewa.
② Te pātaka o te pūkahukahu. Ka whakanohoia te pounamu o roto ki roto i te pounamu o waho, ka hiritia te waha o te pounamu ki roto i te kotahi, ā, ka whakatakotoria he awa mō te whakakikorua hiriwa me te tango hau ki raro o te pounamu o waho. Ka kiia tēnei hanganga karāhe ko te pātaka o te pūkahukahu. E toru ngā momo pātaka o te pounamu karāhe: te tikanga hiri tō raro, te tikanga hiri whakaiti pakihiwi me te tikanga hiri hononga hope. Ko te tikanga hiri tō raro ko te tapahi i te waha o te pātaka o roto o te pounamu me te raro o te pātaka o waho o te pounamu, ka whakakīia te pounamu o roto mai i te raro o te pounamu o waho ka whakapirihia ki te papa whakauru mono asbestos, kātahi ka porowhita ka kati i te raro o te pounamu o waho, ka hono i te awa hiku iti, ka hiri whakarewa i te waha o ngā pounamu e rua. Ko te tikanga hiri whakaiti pakihiwi ko te tapahi i te pātaka o roto o te pounamu, ka tapahia te pātaka o waho o te pounamu, ka whakakīia te pounamu o roto mai i te pito o runga o te pounamu o waho ka whakapirihia ki te papa whakauru mono asbestos, ka whakaiti i te pounamu o waho ki roto i te pakihiwi o te pounamu, ka rewa ka hiri i ngā whakatuwheratanga pounamu e rua, ka hono i te paipa hiku iti. Ko te tikanga hiri hononga hope ko te tapahi i te pounamu o roto me te pounamu o waho, tapahia te hope kia rua ngā wāhanga, ka whakanohoia te pounamu o roto ki roto i te pounamu o waho, ka whakarewahia anō te hope, ka honoa te paipa hiku iti.
③ Whakakikoruatia ki te hiriwa. Ka ringihia he nui o te otinga matū haukini hiriwa me te otinga aldehyde hei kaiwhakaiti ki roto i te paparanga o te pounamu mā roto i te katita hiku iti hei tauhohenga whakaata hiriwa. Ka whakaitihia ngā katote hiriwa ka whakatakotoria ki runga i te mata karāhe hei hanga i te paparanga angiangi o te kiriata whakaata hiriwa.
④ Whakakorekore. Honoa te paipa hiku o te pounamu paparua-rua kua pania ki te hiriwa ki te pūnaha korekorekore, ka whakamahana ki te 300 ~ 400 ℃, kia taea ai e te karāhe te tuku i ngā hau mimiti me te makuku toenga. I taua wā anō, ka whakamahia te papu korekorekore mō te tango hau. Ina tae te nekehanga korekorekore i roto i te wāhi paparua o te arai pounamu ki te 10-3 ~ 10-4mmhg, ka rewa te paipa hiku.
