Ko te Hydroxypropylmethylcellulose (HPMC) he pūhui e whakamahia whānuitia ana i roto i te ahumahi hanga.Ko tana mahi matua ko te whakarei ake i nga ahuatanga mahi o nga rawa penei i te moata me te raima.Ko tetahi o nga tono a HPMC ko te gypsum-based self-leveling, he nui te paanga ki te ahumahi hanga.
Ko te raima-whaiaro he papanga papaa teitei he ngawari ki te whakauru, ka taea te tono ki runga raima, papa tawhito ranei.He whiringa rongonui mo te hanga arumoni me te whare noho na te nui o te mahi me te mauroa.Ko te wero nui i roto i te tono raima-whaiaro ko te pupuri i te kounga me te riterite o nga rawa i te wa e takatu ana me te whakaurunga.Koinei te waahi ka uru mai a HPMC.
Ko te Hydroxypropyl methylcellulose he whakamataketo waihanga ka taapirihia ki nga ranunga whakahiato-whaiaro i runga i te gypsum kia pai ai te tohatoha o te ranunga.Ka awhina ano hoki ki te whakahaere i te kirikiri me te pupuri i te kounga o nga rawa.He mea nui te HPMC i roto i nga ranunga gypsum whakataurite i a ia ano i te mea e whakapumau ana i te ranunga, me te whakarite kia kore te wehewehenga e puta me te whakapai ake i te kaha hononga o te ranunga.
Ko te tukanga tono o te gypsum whakataurite-whaiaro ko te whakaranu i te gypsum ki te HPMC me te wai.Ko te wai hei kaikawe mo te HPMC, kia rite te tohatoha o te ranunga.Ka whakauruhia te HPMC ki te ranunga i te tere o te 1-5% o te taumaha maroke o te gypsum, i runga i te rite e hiahiatia ana me te mutunga o te whakamahinga o te rauemi.
He maha nga painga ki te taapiri i te HPMC ki te ranunga raima-whaiaro.Ka piki ake te mauroa o te rauemi ma te whakanui ake i tona kaha me te aukati ki te wai, matū me te abrasion.I tua atu, ka whakanui ake te HPMC i te ngawari o te rauemi, ka taea e ia te urutau ki nga huringa o te pāmahana me te makuku.Ma tenei ka aukati i nga kapiti, ka whakaiti i nga ururua me te whakanui i te ahua o to papa.
Ka taea hoki e Hydroxypropyl methylcellulose te mahi hei kaiwhakatairanga adhesion ma te whakanui ake i te kaha here o te gypsum whakataurite-whaiaro ki te tïpako.I te wa e whakamahia ana te ranunga, ka whakarite te HPMC kia piri te ranunga ki te taputapu, ka hanga he hononga pumau me te kaha.Ka whakakorehia e tenei te hiahia mo nga taputapu miihini, te whakaora i te wa me te moni i te wa e whakauruhia ana.
Ko tetahi atu painga o te HPMC i roto i te gypsum-based self-leveling ko tana koha ki te oranga o te taiao i roto i te umanga hanga.He pai te taiao o te HPMC me te ngawari ki te tuku atu, na te mea he haumaru me te tauwhiro ki etahi atu matū matū.
Ko te Hydroxypropyl methylcellulose (HPMC) kua kitea he whakauru nui ki roto i nga tono whakataurite-whaiaro i runga i te gypsum.Ma te whai waahi ki te riterite, te kounga me te riterite o te ranunga, ka whakapai ake te HPMC i te mauroa me te rerehua o te rauemi.Ko ona painga o te whakapakari i te kaha here rawa e awhina ana ki te whakaora i te wa me te moni o te umanga.I tua atu, ko te whakamahinga o te HPMC e whakatairanga ana i te oranga o te taiao, na te mea he mea pai ki te umanga hanga.
