1. E ai ki te rauemi whakamahana, ka taea te whakamahi i te waea whakamahana ātete PS, te waea whakamahana PVC, te waea whakamahana rapa silicone, me ētahi atu. E ai ki te rohe mana, ka taea te wehewehe ki ngā momo waea whakamahana e rua: te mana kotahi me te mana maha.
2. Ko te waea whakamahana ātete-PS he waea whakamahana, he tino pai mō te whakapā tika ki te kai, he iti te ātete ki te wera, ā, ka taea anake te whakamahi mō ngā wā iti-mana, ko te tikanga kāore e neke ake i te 8W/m, ko te pāmahana mahi mō te wā roa -25 ℃ ~ 60 ℃.
3. Ko te waea whakamahana 105℃ kua hipokina ki ngā rauemi e rite ana ki ngā whakaritenga o te PVC/E grade i roto i te paerewa GB5023 (IEC227), he pai ake te ātete ki te wera, ā, he waea whakamahana e whakamahia whānuitia ana me te kaha toharite kāore e neke ake i te 12W/m me te pāmahana whakamahi -25℃～70℃. He whānuitia te whakamahinga i roto i ngā pouaka whakamatao, ngā hauhautanga, me ētahi atu hei waea whakamahana ātete-tōmai.
4. He tino pai te ātete wera o te waea whakamahana rapa silicone, ā, he whānuitia te whakamahinga i roto i ngā pouaka whakamātao, ngā pouaka tio me ētahi atu mīhini whakarewa hukapapa. Ko te matotoru o te mana toharite kei raro iho i te 40W/m, ā, i raro i te taiao pāmahana iti me te pai o te tohatoha wera, ka eke te matotoru o te mana ki te 50W/m, ā, ko te pāmahana whakamahinga he -60℃ ~ 155℃.
Kia roa te mahi a te pouaka whakamātao, ka tio tōna mata, ā, i taua wā, ka taea te whakamahi i te waea whakamahana ārai-tio hei whakarewa kia puta ai te wai rewa i roto i te pouaka whakamātao mā te paipa waikeri.
I te mea kua tāutahia te pito o mua o te paipa waikeri ki roto i te pouaka whakamātao, ka tiohia te wai kua rewa i raro i te 0°C hei aukati i te paipa waikeri, ā, me tāuta he waea whakamahana hei whakarite kia kore ai te wai kua rewa e tio i roto i te paipa waikeri.
Ka tāutahia te waea whakamahana ki roto i te paipa rerenga wai hei whakarewa me te whakamahana i te paipa i te wā kotahi kia pai ai te rere o te wai.
