Te tūranga o te hydroxypropyl methylcellulose i roto i te putty
Mai i te whakamātotoru, te pupuri wai me te hanganga o ngā mahi e toru.
Te Whakamātotoru: Ka taea te whakamātotoru i te cellulose kia iri, kia ōrite te otinga, kia ātete hoki ki te totohu. Te pupuri wai: Kia mārō te paura putty, ā, kia āwhina i te tauhohenga o te konupūmā pungarehu i raro i te mahi a te wai. Te Hanganga: He pānga whakahinuhinu te cellulose, ka taea ai te pai o te mahi a te paura putty. Kāore te Hydroxypropyl methylcellulose e whai wāhi ki tētahi tauhohenga matū, ā, he mahi āwhina noa iho. Ka tāpirihia te paura putty ki te wai hei puranga i te pakitara, he tauhohenga matū tēnei, nā te mea kei reira te hanganga o tētahi matū hou ko te konupūmā kāponāte. Ko ngā wāhanga matua o te paura konupūmā pungarehu ko: he ranunga o te konupūmā hauwai Ca(OH)2, te konupūmā waikura CaO me te iti o te konupūmā kāponāte CaCO3. Ka hangaia e te konupūmā pungarehu te konupūmā kāponāte i raro i te mahi a te CO2 i roto i te wai me te hau, ko te hydroxypropyl methyl Cellulose ka pupuri noa i te wai, ā, ka āwhina i te tauhohenga pai ake o te konupūmā pungarehu, kāore nei e whai wāhi ki tētahi tauhohenga.
Tuatahi ka tātarihia e mātou ngā take mō te maturuturunga o te paura o te putty mai i ngā rauemi mata o te putty: te paura konupūmā pungarehu, te hydroxypropyl methylcellulose, te paura konupūmā taumaha, te paura konupūmā pungarehu wai.
1. I roto i te mahi hanga tuturu, hei tere ake i te pirau, ka whakanuia te pāmahana whakapūkara ki te 1000-1100 °C. Nā te rahi o ngā rauemi mata o te kōhatu, nā te koretake rānei o te tohatoha pāmahana i roto i te oumu i te wā e whakapūkara ana, he maha ngā wā kei roto i te kotakota te kotakota kāore i te wera me te kotakota kua wera rawa. Kāore te konupūmā kāponāte i roto i te kotakota e wera ana i te tino pirau, ā, kāore i te kaha piri i te wā e whakamahia ana, kāore e taea te whakarato i te kaha piri ki te putty, ka hua ake te tango paura nā te kore e tino pakeke me te kaha o te putty.
2. Ka nui ake te nui o te konupūmā hauwai i roto i te paura konupūmā pungarehu, ka pai ake te pakeke o te putty e hangaia ana. Engari, ka iti ake te nui o te konupūmā hauwai i roto i te paura konupūmā pungarehu, ka kino ake te pakeke o te putty i te wāhi hanga, ka hua ake te raruraru o te tango paura me te tango paura.
3. Ka konatunatua te paura konupūmā pungarehu ki te nui o te paura konupūmā taumaha, ka iti rawa te ihirangi o te paura konupūmā pungarehu, ā, kāore e ranea te pakeke me te kaha o te putty, ka maturuturu te paura o te putty. Ko te mahi matua o te paura putty he pupuri i te wai, he nui te wai hei whakapakeke i te paura konupūmā pungarehu, ā, he nui te pānga whakapakeke. Mena he raruraru kei te kounga o te hydroxypropyl methylcellulose, he iti rānei te ihirangi whai hua, kāore e taea te whakarato i te makuku e ranea ana, ka kore e ranea te whakapakeketanga, ka maturuturu te paura o te putty.
Ka kitea mai i runga ake nei he tino ngoikore te kounga o te hydroxypropyl methylcellulose, ā, kāore e taea te whakatutuki i tētahi hua, ā, ka taka te paura putty. Ko te take matua he hina te konupūmā taumaha.
