Ko te HPMC (Hydroxypropyl Methyl Cellulose) he cellulose ether e rongonui haere ana i roto i te umanga hanga hei tāpiri ki te putty. Ko te paninga skim ko te paninga o tētahi paparanga angiangi o te rauemi sima ki runga i tētahi mata taratara hei whakangawari, hei hanga hoki i tētahi mata ōrite. I konei ka tūhuratia e mātou ngā painga o te whakamahi i te HPMC ki ngā paninga mārama.
Tuatahi, he mea whakamākū te mahi a te HPMC, arā, ka āwhina i te pupuri i te makuku o te paparanga kiri. He mea nui tēnei nā te mea ki te tere rawa te maroke o te rauemi, ka pakaru, ka mimiti rānei, ka hua ake he mata kāore i te ōrite. Mā te whakaroa i te wā whakamaroke, ka taea e te HPMC te āwhina kia maroke pai ake ngā paparanga kiri, ka hua ake he āhua maeneene ake, he āhua ataahua ake.
Tuarua, he whakamātotoru anō hoki te mahi a te HPMC, arā, ka taea e ia te āwhina ki te whakanui ake i te matotoru o te putty. He tino whai hua tēnei ina mahi ana me ngā rauemi angiangi, wai rānei kua pania ki te kiri, nā te mea ka taea e ia te ārai i ngā maturuturunga me te whakarite kia piri tika te rauemi ki te mata. Mā te whakanui ake i te ōritetanga o te paparanga putty, ka taea hoki e te HPMC te āwhina ki te whakaiti i te tūponotanga o ngā pute hau e puta ana i roto i te rauemi, ka arahi pea ki ngā pakaru me ētahi atu hapa.
Ko tētahi atu painga o te HPMC ko tana āwhina ki te whakapai ake i te ngāwari o te mahi miihini o te putty. Nā te mea he hinu whakahinuhinu tana mahi, e māmā ake ai te whakamahi i te rauemi, ā, e whakarite ana kia ōrite te tohatoha o te rauemi puta noa i te mata. Mā te whakapai ake i te ngāwari o te mahi miihini, ka taea e te HPMC te penapena wā me te kaha i te wā e whakamahia ana, ā, he mea rongonui tēnei mā ngā kaimahi kirimana me ngā kaiwhaiwhai DIY.
Hei tāpiritanga, he tino hototahi te HPMC me ētahi atu tāpiringa e whakamahia whānuitia ana i roto i ngā wanihi, pērā i te rapa me ngā here kiriaku. Ko te tikanga ka taea te whakamahi tahi me ēnei rauemi hei whakatutuki i ngā āhuatanga mahi motuhake, pērā i te whakapai ake i te piri, te ātete wai rānei. Mā te whakarei ake i te mahi whānui o ngā putty, ka taea e te HPMC te āwhina ki te whakaroa i te roa o te ora o ngā mata kua oti, me te whakaiti i te hiahia mō ngā whakatikatika utu nui, ngā whakakapinga rānei.
He mea tika hoki kia whakahuatia ngā painga taiao o te whakamahi i te HPMC. He pūmua tūturu i ahu mai i te cellulose, he pirau-ora, kāore hoki e paitini, ā, he mea haumaru ake, he mea pumau ake hoki hei whakakapi i ngā tāpiringa hangai. Hei tāpiri, nā te mea he wairewa ki te wai, kāore he mōrearea o te poke i te wai whenua, i ētahi atu pūnaha wai rānei i te wā e whakamahia ana, e horoia ana rānei.
Hei whakamutunga, he tāpiringa putty maha-mahi, he whai hua hoki te HPMC, he maha ngā painga e pā ana ki te pupuri wai, te whakamātotoru, te hanga, te hototahi me te pumau. Mā te whakauru i te HPMC ki roto i ā rātou rauemi paninga kiri, ka taea e ngā kaimahi kirimana me ngā kaimahi DIY te whakatutuki i ngā mata maeneene ake, he ōrite ake, me te whakapai ake i te mahi me te pakari.
