Ina teitei te pāmahana, ā, ka haere tonu te ua, ehara i te mea ka pā noa ki te mahi whakaputa o tā mātou wheketere, engari he maha hoki ngā kaihoko e āwangawanga ana mō te rokiroki o ngā hiri.
Ko te hiri silicone he rapa silicone whakamomona i te pāmahana rūma. He whakapiri i hangaia mai i te rapa silicone 107 me te whakakī hei rauemi mata matua, ā, he mea tāpiri atu ki te kaihoko hononga, te kaihoko thixotropic, te kaihoko hononga, me te whakakorikori i roto i te āhua korehau. Ka tauhohe ki te wai i te hau, ka totoka hei hanga rapa silicone ngāwari.
He tino kaha ngā whakaritenga mō te taiao rokiroki mō ngā hua hiri silicone. Mā te taiao rokiroki kino ka whakaitihia te mahi a te hiri silicone, ka whakapakeketia rānei. I ngā wā tino kino, ka ngaro te mahi a tētahi wāhanga o ngā hiri silicone, ā, ka waiho kia para te hua.
Me kōrero tātou mō ētahi tohutohu mō te rokiroki i ngā hiri silicone.
I roto i te taiao pāmahana teitei, ka tere ake te koroheketanga o te hiri silicone, ka puta he āhuatanga "whakaiti", ka tere ake te ngaronga o ētahi āhuatanga, ā, ka whakapoto i te roa o te wā e ora ai. Nō reira, he nui te pānga o te pāmahana rokiroki ki te kounga o te hiri silicone, ā, me kaua e neke ake te pāmahana rokiroki i te 27°C (80.6°F).
I roto i te taiao pāmahana iti, ka meinga e te pāmahana taiao tino iti te whakatio o te kaihoko hono me te kaihoko honohono i roto i te kāpia silicone. Ka puta he āhua kino o te kāpia i ngā tioata, ā, ka kore e ōrite ngā tāpiringa ā-rohe. I te wā e whakarārangihia ana, ka taea te whakaora ā-rohe i te colloid engari kāore e whakaora ā-rohe. Nō reira, kāore e taea te whakamahi i te hiri silicone kua whakatio. Hei ārai i te whakatio o te rapa silicone, kaua te taiao rokiroki e iti iho i te -5°C (23℉).
I roto i te taiao haumākū nui, ka totoka te hiri silicone ina tūtaki ki te kohu wai. Ka nui ake te haumākū whanaunga i roto i te taiao rokiroki, ka tere ake te maroke o te hiri silicone. He maha ngā hiri silicone e whakaputa ana i te nui o te hiri maroke i roto i te 3-5 marama i muri i te hanga, he mea e pā tika ana ki te haumākū whanaunga o te taiao rokiroki he nui rawa, ā, he tika ake te tono kia ≤70% te haumākū whanaunga o te taiao rokiroki.
I te katoa, me penapena ngā hua rapa silicone ki tētahi wāhi maroke, hauhautanga, me te hauhautanga. Ko te pāmahana rokiroki pai rawa atu kei waenganui i te -5 me te 27°C (23--80.6℉), ā, ko te haumākū rokiroki pai rawa atu he ≤70%. Ka ārai i te penapena ki ngā wāhi e pāngia ana e te hau, te ua, me te rā tika. I raro i ngā tikanga kawe me te rokiroki noa, ko te wā rokiroki he 6 marama te iti rawa mai i te rā i hangaia ai.
Hei ārai i te hekenga o te kounga o ngā hua rapa silicone i te wā e rongoatia ana, me whakanoho te whare putunga ki tētahi wāhi matao, kāore he rā tika. Kāore hoki e taea te whiriwhiri i ngā wāhi iti e ngāwari ana ki te kohikohi wai. Mō ngā whare putunga he nui te pāmahana, me mahi pai tātou ki te whakamatao i te tuanui. Ko te whare putunga me te paparanga whakamahana i runga i te tuanui te mea pai rawa atu, ā, me whakapūhaumātao anō hoki i te wā kotahi. Mena ka taea e ngā āhuatanga, me whakauru te whare putunga ki ngā hauhautanga me ngā whakamaroke hau hei pupuri i te pāmahana me te haumākū o te whare putunga i te raumati me te wā ua.
