I te whanaketanga tonu o te hangarau hanga whare hou, kua noho te Pūnaha Whakamarumaru me te Whakaoti o Waho (EIFS) hei otinga nui i roto i te mara o ngā whare penapena hiko. Hei whakapai ake i te mahi a te EIFS, ko te tono ohydroxypropyl methylcellulose (HPMC)Kei te piki haere te hiranga o te mahi hangahanga. Ehara i te mea ka arotau noa te HPMC i te mahi hangahanga, engari ka whakanuia ake hoki te roa me te penapena pūngao o te pūnaha.
Te mātāpono mahi me ngā wero o te EIFS
He pūnaha whakakotahi te EIFS e whakauru ana i te whakamarumaru o te pakitara o waho me ngā mahi whakaoti. Kei roto i te nuinga o te wā ko ngā panera whakamarumaru, ngā piripiri, te kakahu mata whakakaha, te paninga turanga me te paninga mata whakapaipai. He pai te mahi whakamarumaru wera a te EIFS me ngā āhuatanga mama, engari he raruraru hangarau anō hoki kei roto i ngā mahi mahi, pērā i te koretake o te mahi hanga piripiri, te pakaru o te paninga, me te mimiti nui o te wai. Ka pā tika ēnei raruraru ki te roa o te pūnaha, te āhua me te ataahua.
Ngā āhuatanga mahi oHPMC
He matū cellulose ether tino mahi te HPMC, e mōhiotia ana mō ōna āhuatanga whakamātotoru, pupuri wai me te whakarerekētanga pai i roto i ngā rauemi hanga. Ko ōna mahi matua i roto i te EIFS ko:
Te pupuri wai pai ake: Ka whakanui ake te HPMC i te kaha pupuri wai o te hononga me te paninga, ka roa ake te wā mahi hanga, me te whakarite hoki kia taurite te makuku o ngā rauemi sima i te wā e whakapakeke ana kia kore ai e ranea te kaha, e pakaru rānei i puta mai i te tere o te ngaronga wai.
Te arotau i te mahi hanga: Ka whakapai ake te HPMC i ngā āhuatanga rheological o te mea here, ā, ka whakanui ake i tōna ātete ārai-totoka, ka māmā ake te paninga ki te paninga, ā, he pai hoki te horapa, kia pai ake ai te whai huatanga me te kounga o te hanga.
Te kaha o te hononga: Mā te tohatoha ōrite o te HPMC ka taea te whakapai ake i te matotoru me te piri o te kāpia, ka hanga he hononga kaha i waenga i te papa whakamahana me te pakitara.
Te ātete pai ake ki te pakaru: Mā te whakanui ake i te ngāwari o te moata, ka ārai pai te HPMC i te pakaru o te paninga nā te huringa pāmahana, te rerekētanga rānei o te paparanga turanga.
Ngā tono motuhake o te HPMC i roto i te EIFS
I roto i te EIFS, e whakamahia ana te HPMC i ngā āhuatanga e whai ake nei:
Te moata honohono: Whai muri i te tāpiri i te HPMC, ka pai ake te mahi me te piri o te moata honohono, kia kore ai te papa whakamahana e neke i te wā hanga.
Paparanga whakakaha moata: Mā te tāpiri i te HPMC ki te paparanga whakakaha ka taea te whakapai ake i te pakari me te ātete ki te pakaru o te moata, ā, i te wa ano ka whakarei ake i te pānga paninga o te mata karāhe muka.
Paninga mata whakapaipai: Mā ngā āhuatanga pupuri wai me te matotoru o te HPMC ka pai ake te paninga whakapaipai, ka pai ake hoki te pānga peita, me te whakaroa ake i te wā whakatuwheratanga me te whakaiti i ngā hapa hanga.
Te whakapai ake i te mahi o te whare
Mā te whakamahi i te HPMC i roto i te EIFS, ka whakapaitia te mahi a te whare puta noa i te poari:
Te pānga whakaora pūngao kua whakarei ake: Mā te hononga piriti wera i waenganui i te papa whakamarumaru me te pakitara ka whakaitihia te pānga piriti wera, ā, mā te tohatoha ōrite o te HPMC ka whakarite kia pumau me te mahi whakamarumaru wera o te paparanga moata.
Te pakari ake: He ātete ake te moata me te paninga kua whakarerekētia ki te ngatata me te huarere, ka roa ake ai te roa o te ora o te pūnaha.
Te whakapai ake i te whai huatanga o te hanga: Ka whakapai ake te HPMC i te mahi hanga, ka nui ake te whai huatanga me te tika o te tukanga hanga, ā, ka whakaitihia hoki ngā utu mahi anō.
Te kounga āhua kua whakapaitia: He papatahi ake te paninga whakapaipai, ā, he ōrite ake te tae, kia ataahua ake ai te āhua o te whare.
Hei tāpiri matua i roto i te EIFS,HPMCKa āwhina i te arotau i te pūnaha me tana mahi tino pai, ka whakarato i ngā otinga whai hua me te roa mō ngā whare hou e penapena ana i te hiko. I te heke mai, i te mea kei te piki haere tonu te umanga hanga i ana whakaritenga mō te mahi teitei me te pumau, ka whānui ake ngā tūmanakohanga tono o te HPMC i roto i te EIFS.
