Ko te paura putty he rauemi hanga e whakamahia whānuitia ana, he mea hanga te nuinga ki te gypsum me ētahi atu tāpiringa. Ka whakamahia hei whakakī i ngā āputa, i ngā hononga me ngā kapiti i roto i ngā pakitara me ngā tuanui. Ko te Hydroxypropylmethylcellulose (HPMC) tētahi o ngā tāpiringa e whakamahia whānuitia ana i roto i te paura putty. He pai te mahi pupuri wai me te piri pai, ka taea te whakapai ake i te mahi me te kaha o te putty. Heoi, ka pāngia te kounga o te HPMC cellulose e ngā āhuatanga maha, pērā i te whakaoho me te waimeha.
He taahiraa nui te whakaoho i roto i te whakarite i te paura putty. Mā tēnei ka whakarite kia ōrite te tohatoha o ngā kai katoa, ā, kia kore he puranga me ētahi atu hapa i roto i te hua whakamutunga. Heoi, mā te whakaoho nui rawa ka hua ake he cellulose HPMC kounga iti. Mā te whakaoho nui rawa ka pakaru te cellulose, ka whakaiti i tōna pupuri wai me ōna āhuatanga piri. Nō reira, kāore pea te putty e piri tika ki te pakitara, ā, ka pakaru, ka tihore rānei i muri i te paninga.
Hei karo i tēnei raruraru, he mea tino nui kia whai i ngā tohutohu a te kaihanga mō te whakaranu i te paura putty. I te nuinga o te wā, ka tohua e ngā tohutohu te nui o te wai e tika ana me te roa o te whakaoho. Ko te mea pai, me whakaoho pai te putty kia whiwhi ai i te kakano maeneene, ōrite hoki, me te kore e pakaru te cellulose.
Ko te whakangawari tetahi atu mea nui e pā ana ki te kounga o te cellulose HPMC i roto i te paura putty. Ko te whakawaiwai ko te tāpiri wai, ētahi atu whakarewa rānei ki te putty kia māmā ake ai te hora me te hanga. Heoi, mā te tāpiri nui rawa o te wai ka waimeha te cellulose, ka whakaiti i ōna āhuatanga pupuri wai. Ka tere rawa te maroke o te putty, ka pakaru, ka mimiti.
Hei karo i tēnei raruraru, he mea nui kia whai i ngā tohutohu a te kaihanga mō te whakawai i te paura putty. I te nuinga o te wā, ka tohua e ngā tohutohu te nui o te wai, te whakarewa rānei e tika ana hei whakamahi me te roa o te whakaranu. E taunakihia ana kia tāpirihia he iti noa te wai, ā, kia pai te whakaranu i mua i te tāpiri. Mā tēnei ka whakarite kia marara tika te cellulose ki roto i te putty, ā, kia mau tonu ōna āhuatanga pupuri wai.
Hei whakarāpopototanga, ka pā te whakaoho me te whakakōkī ki te kounga o te HPMC cellulose i roto i te paura putty. He mea nui kia āta whai i ngā tohutohu a te kaihanga kia mau tonu ai te cellulose ki te pupuri wai me te piri. Mā te mahi i tēnei, ka taea te whiwhi i tētahi putty kounga teitei ka puta he hua pai rawa atu, ā, ka roa te piri me te pakari.
