Taumata hangahangahydroxypropyl methylcellulose (HPMC)He etera cellulose wairewa-wai tēnei e whakamahia whānuitia ana. Nā tōna pai ki te pupuri i te wai, ki te matotoru, me te pumau, ka whakamahia whānuitia i roto i ngā rauemi hanga, inā koa ko te putty pakitara. Hei rauemi nui mō te whakapaipai whare, ka pā tika te mahi me te pānga paninga whakamutunga o te putty pakitara ki te ataahua me te pakari o ngā whare. Mā te tāpiri o te HPMC ka taea te whakapai ake i te mahi o te putty, ka maeneene ake te hanganga, ka ōrite ake te mata o te pakitara.
1.Ko te mahi matua a te HPMC hanga-whakairoiro i roto i te putty ko te pupuri i te wai. Me pupuri te putty kia makuku i te wā hanga kia pai ai te mahi me te piri. I muri i te rewa ki te wai, ka hangaia e te HPMC he whatunga hydrogel ōrite ka taea te raka i te makuku me te whakaroa i te tere mimiti, ā, ka roa ake te wā tuwhera o te putty, ka hoatu hoki he wā ki ngā kaimahi hanga mo te whakataurite me te whakaoti i te wā tono. I taua wā anō, ko te pupuri pai i te wai ka ārai i te putty mai i te pakaru, i te tihore rānei mena ka maroke wawe rawa, ka whakarite kia maeneene me te pakari te mata o te pakitara.
2.He tino pai ngā āhuatanga whakamātotoru me te whakatārewatanga o te HPMC. Ka tau te paura putty i muri i te whakaranua ki te wai, ka hanga he puranga, he paparanga wai rānei. Ka whakanuia e te HPMC te matotoru o te wāhanga wai, ka hanga kia ōrite, kia pumau hoki te paru putty, ka taea ai te taurewa i roto i te wai, ā, ka karohia ngā raruraru paparanga me te taunga. Ehara i te mea ka āwhina noa i te whakamahinga kotahi o te putty i te wā hangahanga engari ka whakaitihia hoki te para, ā, ka whakapai ake i te whai huatanga o te hangahanga.
3.Ka whakapai ake hoki te HPMC i te piri me te ngāwari o te mahi o te putty. Ka hanga he hanganga whatunga tonu i roto i te paru putty, ka whakanui ake i te piri i waenga i te putty me te mata o te papa, ka whakaiti i te paura me te kiri i te wā hanga. I te wa ano, na tona hinu whakahinuhinu, ka maeneene te putty, ka ngawari hoki te paninga e te HPMC, ka whakaiti i te tūponotanga o ngā karawarawa, te ahua kirikiri rānei, ka whakapai ake i te maeneene me te hua whakapaipai o te mata pakitara.
4.I roto i ngā mahi whaihua, me whiriwhiri te nui me te taumata matotoru o te HPMC e whakamahia ana i runga i te hanganga o te putty me te taiao hanga. I te nuinga o te wā, ka whakamahia te HPMC iti-makuku ki roto i te putty māmā, i te putty parai rānei hei whakarite kia ngāwari te whakaranu me te tono maeneene; i te mea ka taea te whiriwhiri i te HPMC matotoru-waenga ki te teitei mō te putty matotoru, te putty whakataurite rānei hei whakarei ake i te pupuri wai me ngā āhuatanga whakatārewatanga. Hei tāpiri, ka pā te pāmahana me te haumākū i te papa hanga ki te pupuri wai o te HPMC, me whakarerekē tika te horopeta kia pai ai te mahi i raro i ngā āhuatanga rerekē.
5.Te taumata hoahoangaHPMCHe nui ngā painga o te putty pakitara. Mā te whakapai ake i te pupuri wai o te putty, te matotoru o ngā āhuatanga, te piri, me te ngāwari o te mahi, ehara i te mea ka whakarei ake te HPMC i te whai huatanga o te hanga engari ka whakarite hoki i te ataahua me te pakari o te whakaotinga pakitara whakamutunga. I roto i te hanganga hou, kua riro te HPMC hei tāpiringa tino nui i roto i ngā hanganga putty, he mea nui ki te whakapai ake i te kounga o ngā rauemi hanga me te hanganga.
