Te Painga o te HPMC i runga i nga Hua-a-Gypsum

Kua roa te whakamahi a Gypsum i roto i te umanga hanga na te mea he maha nga mahi me te whanui o te whakamahinga. He kore-paitini, he ahi-atete, he kore-whakaahua, he tino mahi me te ratarata-kaiwhakamahi, ka taea e ona kaiwhakamahi te hanga i nga whakapaipai ataahua. He pai rawa atu te waiariki me te oro o te gypsum.

Ko te nuinga o nga whakamahinga o nga hua gypsum i roto i te ahumahi hanga ko te gypsum precast taiepa me te gypsum ceiling plasterboard, gypsum self-leveling mortas, gypsum hand-applying or machine-apply plasters, gypsum trowelable compounds, gypsum joint fillings and gypsum adhesives.

Ko nga ahuatanga me nga mahi o te gypsum ka taea te whakapai ake ma te whakamahi i nga taapiri e pa ana. Hua Cellulose Etera Hydroxypropyl Methyl Cellulose (HPMC), Hydroxy Ethyl Methyl Cellulose (HEMC) he mea hanga motuhake hei taapiri mahi teitei hei huri i nga hua sima-a-wai-a-papa ki nga tohu utu nui me nga taonga hanga whare e rapuhia ana.

raima troweling pūhui

He rereke mai i te kirikiri me te tikanga ciment i whakamahia i roto i te hanga tuku iho, ka whakamahia e te puhui raima gypsum te gypsum hei rauemi taketake me te polymer molecular teitei hei rauemi cimentitious, he pai te hototahi me te piri kaha ki nga papa hanga noa.

Ko te Hydroxypropylmethylcellulose (HPMC), Hydroxyethylmethylcellulose (HEMC) kua hangaia hei whakarato i nga whakapainga e whai ake nei ki nga puhui raima raima:

He pai te pupuri wai me te wa mahi roa

Ko te riterite o nga hua me te rheology

whakaiti i te hanga kapia

Whakapai ake i te adhesion me te whakahekeheke

raima whakakī hononga

Ka whakamahia te whakakii hono ki te whakaki i nga hononga i waenga i te papa gypsum me te papa muka.

Ko te Hydroxypropylmethylcellulose (HPMC), Hydroxyethylmethylcellulose (HEMC) kua hangaia hei whakarato i nga whakapainga e whai ake nei ki nga puhui raima raima:

Ka whakapai ake i te kaha o nga hononga me te ngawari, ka whakaiti i te tupono o te pakaru o nga hononga i raro i te roha me te whakaheke

He pai te pupuri wai me te wa mahi roa

Ko te riterite o nga hua me te rheology

whakaiti i te hanga kapia

Whakapai ake i te adhesion me te whakahekeheke
