Mō te raruraru he ngāwari te paura putty ki te paura, kāore rānei i te rawaka te kaha. E mōhio ana tātou katoa, me tāpiri te cellulose ether hei hanga paura putty, ka whakamahia te HPMC mō te putty pakitara, ā, he maha ngā kaiwhakamahi kāore e tāpiri i te paura rapa ka taea te whakamarara anō. He maha ngā tāngata kāore e tāpiri i te paura polymer hei penapena utu, engari koinei anō te take he ngāwari te putty noa ki te paura, ā, he ngāwari ki te raru te kounga o te hua!
Ko te putty noa (pērā i te putty 821) he mea hanga te nuinga ki te paura ma, he iti noa te kāpia māngaro me te CMC (hydroxymethyl cellulose), ā, ko ētahi he mea hanga ki te methyl cellulose me te paura Shuangfei. Kāore he piri o tēnei putty, ā, kāore e ātete ki te wai.
Ka taea e te cellulose te mimiti i te wai, ā, ka pupuhi i muri i te whakarewanga ki te wai. He rerekē ngā tere mimiti wai o ngā hua mai i ngā kaihanga rerekē. He mahi tā te cellulose ki te pupuri wai i roto i te putty. He kaha wā poto noa iho te putty maroke, ā, ka āta memeha haere i muri i te wā roa. He hononga tata tēnei ki te hanganga ngota o te cellulose tonu. He wetewete taua putty, he nui te mimiti wai, he ngāwari ki te pakaru, kāore he kaha, ā, kāore he ngāwari. Ki te pania he paninga o runga, ka ngāwari te pakaru me te pahuka i te PVC iti; ka ngāwari te whakaiti me te pakaru o te PVC teitei; nā te nui o te mimiti wai, ka pā ki te hanganga kiriata me te pānga hanga o te paninga o runga.
Ki te hiahia koe ki te whakapai ake i ngā raruraru o runga ake nei mō te putty, ka taea e koe te whakarerekē i te tātai putty, tāpirihia he paura rapa ka taea te whakamarara anō kia tika ai te whakapai ake i te kaha o muri mai o te putty, ā, whiriwhiria te HPMC hydroxypropyl methylcellulose kounga teitei me te kounga kua oti te whakapūmau.
I roto i te tukanga hanga putty, ki te kore e ranea te nui o te paura rapa ka taea te whakamarara anō, ki te whakamahia rānei he paura rapa ngoikore mō te putty, he aha te pānga ki te paura putty?
Kāore i te rawaka te paura rapa ka taea te whakamarara anō i te putty, ko te whakaaturanga tino tika ko te paparanga putty he marara, he pakaru te mata, he nui te nui o te peita e whakamahia ana mō te paninga o runga, he ngoikore te āhuatanga whakataurite, he taratara te mata i muri i te hanganga o te kiriata, ā, he uaua ki te hanga i tētahi kiriata peita matotoru. Ka ngawari te kiri peita o ēnei pakitara ki te tihore, ki te pupuhi, ki te tihore, ki te ngatata. Ki te whiriwhiri koe i te paura putty ngoikore, he mārama ko ngā hau kino pēnei i te formaldehyde e hangaia ana i runga i te pakitara ka whara tinana i ētahi atu.
