He momo rauemi whakapaipai whare te paura putty, ko ngā wāhanga matua ko te paura taruku me te kāpia. Ko te paparanga mā i runga i te mata o te rūma kau i hokona mai nei he putty. Ko te tikanga he neke atu i te 90° te mā o te putty, ā, he neke atu i te 330° te pai.
He momo rauemi turanga te putty e whakamahia ana mō te whakatika pakitara, e whakatakoto ana i te turanga pai mō te taahiraa whakapaipai e whai ake nei (te peita me te pepapātū). E rua ngā momo putty: te putty o roto o te pakitara me te putty i runga i te pakitara o waho. Ka taea e te putty pakitara o waho te ātete i te hau me te rā, nō reira he pai te whakakī, he kaha teitei, ā, he iti te taupū taiao. He pai te taupū whānui o te putty i roto i te pakitara o roto, ā, he akuaku, he pai hoki mō te taiao. Nō reira, kāore te pakitara o roto e whakamahia mō te whakamahi o waho, ā, kāore te pakitara o waho e whakamahia mō te whakamahi o roto. Ko ngā putty he mea hanga ki te gypsum, ki te sima rānei, nō reira he māmā ake te piri ki ngā mata taratara. Heoi, i te wā e hanga ana, me parai tonu he paparanga o te kaihoko atanga ki runga i te turanga hei hiri i te turanga me te whakapai ake i te piri o te pakitara, kia pai ake ai te piri o te putty ki te turanga.
He tokomaha ngā kaiwhakamahi paura putty me whakaae he raruraru nui te tango paura putty. Ka taka te peita rapa, ka pupuhi, ka ngatata hoki te paparanga putty, ka pakaru te peita rapa.
Ko te tango paura me te whakama i te paura putty ngā raruraru tino kitea i muri i te hanganga putty. Hei mārama ki ngā take mō te tango paura putty, me mārama tuatahi tātou ki ngā wāhanga taketake o te rauemi mata me ngā mātāpono whakamaroke o te paura putty, kātahi ka whakakotahi i te mata o te pakitara i te wā e hangaia ana te putty: te maroke, te mimiti wai, te pāmahana, te maroke o te rangi, me ētahi atu.
E waru ngā take matua e marere ai te paura putty.
take tuatahi
Kāore i te rawaka te kaha o te piri o te putty hei tango i te paura, ā, ka whakaitihia e te kaihanga te utu. He ngoikore te kaha o te piri o te paura rapa, ā, he iti te nui o te tāpiri, inā koa mō te putty pakitara o roto. Ā, he nui te pānga o te kounga o te kāpia ki te nui o te tāpiri.
Take tuarua
He mea tino nui te tauira hoahoa koretake, te whiriwhiri rauemi me ngā raruraru hanganga i roto i te tauira putty. Hei tauira, ka whakamahia te hydroxypropyl methylcellulose (HPMC) hei putty kore-wai mō te pakitara o roto. Ahakoa he tino utu nui te HPMC, kāore e mahi mō ngā whakakī pēnei i te paura rere rua, te paura talcum, te paura wollastonite, me ētahi atu. Mena ka whakamahia anake te HPMC, ka puta he wehewehenga. Heoi, kāore te CMC me te CMS me ngā utu iti e tango i te paura, engari kāore e taea te whakamahi i te CMC me te CMS hei putty kore-wai, kāore hoki e taea te whakamahi hei putty pakitara o waho, nā te mea ka tauhohe te CMC me te CMS ki te paura konupūmā hina me te sima mā, ka puta he wehewehenga. Kei reira anō ngā polyacrylamides i tāpirihia ki te paura konupūmā raima me te sima mā hei paninga kore-wai, ka puta hoki he tauhohenga matū hei tango i te paura.
Take Tuatoru
Ko te whakaranu kore taurite te take matua mō te tango paura o te putty i ngā pakitara o roto, o waho hoki. Ko ētahi kaihanga o te motu e whakaputa ana i te paura putty me ngā taputapu māmā, rerekē hoki. Ehara i te mea he taputapu whakaranu motuhake, ā, ko te ranunga kore taurite te take o te tango paura o te putty.
Take tuawhā
Nā te hapa o te tukanga whakaputa ka paura te putty. Mēnā kāore he mahi horoi a te mīhini whakaranu, ā, he nui ake ngā toenga, ka tauhohe te CMC i roto i te putty noa ki te paura konupūmā pungarehu i roto i te putty ātete wai. Ka tauhohe te CMC me te CMS i roto i te putty pakitara o roto, me te sima mā o te putty i roto i te pakitara o waho, ka puta te tango paura. He putanga horoi kei ētahi taputapu motuhake a ētahi kamupene, ka taea te horoi i ngā toenga i roto i te mīhini, ehara i te mea hei whakarite i te kounga o te putty anake, engari hei whakamahi hoki i te mīhini kotahi mō ngā kaupapa maha, me te hoko i te taputapu kotahi hei whakaputa i ngā momo putty.
Take Tuarima
Tērā pea ka puta te tango paura i te rerekētanga o te kounga o ngā whakakī. He nui ngā whakakī e whakamahia ana i roto i te putty pakitara o roto, o waho hoki, engari he rerekē te nui o te Ca2CO3 i roto i te paura konupūmā taumaha me te paura talc i ngā wāhi rerekē, ā, mā te rerekētanga o te pH ka puta hoki te tango paura o te putty, pērā i ērā i Chongqing me Chengdu. Ko te paura rapa kotahi e whakamahia ana mō te paura putty pakitara o roto, engari he rerekē te paura talc me te paura konupūmā taumaha. I Chongqing, kāore e tangohia te paura, engari i Chengdu, kāore e tangohia te paura.
take tuaono
Ko te take o te rangi tētahi atu take mō te tango i te paura o te putty i ngā pakitara o roto, o waho hoki. Hei tauira, he maroke te āhuarangi o te putty i ngā pakitara o roto, o waho hoki, ā, he pai te hauhautanga i ētahi wāhi maroke o te raki. He ua te rangi, he roa te haumākū, kāore i te pai te āhua o te putty ki te hanga kiriata, ā, ka ngaro hoki te paura, nō reira he pai ētahi wāhi mō te putty ātete wai me te paura konupūmā.
take whitu
He poke ngā here kore-waro pēnei i te paura konupūmā hina me te sima mā, ā, he nui te paura rere rua kei roto. Ko ngā mea e kiia nei ko te paura konupūmā hina maha-mahi me te sima mā maha-mahi kei te mākete he poke, nā te mea he nui te nui o ēnei here kore-waro poke e whakamahia ana, ā, ko te putty ā-wai o ngā pakitara o roto, o waho hoki ka tino kore-paura, ā, kāore e ā-wai.
take waru
I te raumati, kāore e ranea te pupuri wai o te putty i ngā pakitara o waho, inā koa i ngā wāhi he nui te pāmahana me te hauhautanga pērā i ngā tatau me ngā matapihi teitei. Ki te kore e ranea te wā tīmatanga o te whakatakoto o te paura konupūmā me te sima, ka ngaro te wai, ā, ki te kore e tiakina pai, ka tino paura hoki.
