He rauemi whai hua, he maha ngā whakamahinga o te whakamahana pahuka rehu, e whakamahia ana i roto i te umanga hanga me te whakamahana hei whakapai ake i te whai huatanga o te pūngao me te hanganga pai. Ko te nuinga o te wā he ranunga matū e tauhohe ana hei hanga pahuka e whānui ana, e whakarato ana i ngā āhuatanga whakamahana pai rawa atu mā te hiri i ngā āputa, ngā kapiti, me ētahi atu wāhi e ngawari ana ki te turuturu o te hau. He whānuitia te whakamahinga o tēnei rauemi whakamahana i roto i ngā whare noho, arumoni, me ngā whare ahumahi, e tuku ana i te mahi wera pai rawa atu me te penapena pūngao.
He aha te mea hanga o te whakamahana pahuka rehu?
Ko te whakamahana pahuka rehu e hangaia ana mai i ngā wāhanga wai matua e rua: ko ngā isocyanate me ngā polyol. Ina konatunatua ēnei wāhanga e rua, ka tauhohe hei hanga i te pahuka ka whakawhanui, ka whakapakeke. Ko te mea nui o tēnei tukanga ko te whakamahinga o ngā whakakorikori polyurethane motuhake e whakahaere ana i te tere tauhohenga, kia tika ai te whakamaroke o te pahuka, kia tutuki ai ngā āhuatanga whakamahana e hiahiatia ana.
1. Ngā Isocyanate:
He matū tauhohe ngā isocyanates e whai wāhi nui ana ki te hanganga o te pahuka polyurethane. Ka tauhohe rātou ki ngā polyol hei hanga i te hanganga polymer polyurethane, e homai ana ki te pahuka tōna hanganga me tōna pakari.
2. Ngā Polyol:
Ko ngā polyol tētahi atu wāhanga nui o te whakamahana pahuka rehu. Ka konatunatua ēnei ki ngā isocyanate hei whakaputa i te pahuka polyurethane. Ka rerekē te momo me te hanganga o ngā polyol, ka taea ai te whakaputa i ngā āhuatanga pahuka rerekē, pērā i te ngāwari, te pakari, me te mātotoru.
3. Ngā Whakakōkī Polyurethane:
He mea nui ngā whakakorikori polyurethane hei whakahaere i te tauhohenga i waenga i ngā isocyanates me ngā polyols. Mā ēnei whakakorikori ka whakawhanuitia te pahuka, ka maroke tika, ka whakarato i ngā āhuatanga whakamarumaru e hiahiatia ana. Hei tauira, ko teMXC-A33Ka whakamahia te whakakorikori hei whakaputa i ngā mirumiru pahuka ngohengohe, mārō, me te āhua mārō, kia maha ai ngā whakamahinga mō ngā momo hiahia whakamahana. Ka taea hoki te rewa ki roto i ngā whakarewa pēnei i te MEG, DEG, me te BDO, kia taea ai te whakamahi i ngā momo tono. I tētahi atu taha,MXC-Te whakamahia ana i roto i te hanga pahuka ngāwari polyether, pahuka whakarewa, pahuka āhua-pakari, me te pahuka maro, kia pai ai mō ngā tono whakamahana motuka.
Ngā Whakamahinga o te Whakamarumaru Pahuka Rehu
He maha ngā whakamahinga o te whakamahana pahuka rehu, tae atu ki:
- Te Āraitanga Whare NohoE whakamahia whānuitia ana te pahuka rehu i roto i ngā kāinga hei whakamarumaru i ngā pakitara, i ngā tuanui, me ngā rūma tuanui, hei āwhina i te whakaiti i ngā utu pūngao me te whakapai ake i te whakamarie.
- Ngā Whare PakihiE whakamahia ana hoki i roto i ngā hanganga arumoni hei ārai i ngā wāhi nunui, hei whakarato i tētahi taiao whakahaere pai ake, hei whakaiti hoki i ngā whakapaunga whakamahana me te whakamatao.
- Ngā Taupānga AhumahiE whakamahia ana te whakamahana pahuka rehu i roto i ngā taiao ahumahi hei whakamahana i ngā paipa, ngā tāke me ētahi atu taputapu, hei ārai i te ngaronga pūngao me te whakarei ake i te whai huatanga.
Whakamutunga
He rauemi tino whai hua te whakamahana pahuka rehu polyurethane e tuku ana i ngā āhuatanga whakamahana tino pai. Mā te whakamahinga o ngā whakamahana motuhake pēnei i te MXC-A33 me te MXC-T ka whakarite kia pai te maroke o te pahuka, ka whakarato i ngā āhuatanga whakamahana e hiahiatia ana mō ngā mahi maha. Ahakoa i roto i ngā wāhi noho, arumoni, ahumahi rānei, he taputapu tino nui te whakamahana pahuka rehu hei whakarei ake i te whai huatanga o te pūngao me te hanganga pai.
