He maha nga mea e pa ana ki te whakamahinga o te hydroxypropyl methylcellulose HPMC i roto i nga taonga hanga whare, ina koa te raima-a-gypsum, penei:
1 te pupuri wai
Ko te Hydroxypropyl methylcellulose mo te hanga ka aukati i te whakaurunga nui o te wai e te tïpako, a, ka oti te gypsum, me pupuri te wai i roto i te raima ka taea.Ko tenei ahuatanga e kiia ana ko te pupuri wai, he rite tonu ki te pokey o te otinga hydroxypropyl methylcellulose hanga-motuhake i roto i te stucco.Ko te teitei ake o te pokey o te otinga, ka nui ake tona kaha pupuri wai.Kia piki ake te nui o te wai, ka heke te kaha pupuri wai.Ko te mea tenei na te nui o te wai ka waimeha i te otinga o te hydroxypropyl methylcellulose mo te hanga, ka heke te pokey.
2 anti-sagging
Ko te raima me nga taonga anti-sag ka taea e nga kaitono te whakauru i nga koti matotoru me te kore e paheke, a ko te tikanga ko te raima ake ehara i te thixotropic, ka paheke ki raro i te wa e tono ana.
3 Whakaitihia te pokey, ngawari te hanga
Ka taea te whiwhi te raima gypsum iti-poka me te ngawari ki te hanga ma te taapiri i nga momo hua hydroxypropyl methylcellulose hangahanga motuhake.A, no te whakamahi i nga tohu iti-nui o te whare-motuhake hydroxypropyl methylcellulose, ka iti ake te tohu o te viscosity Ka ngawari ake te hanga, engari he ngoikore te kaha o te pupuri wai o te hydroxypropyl methylcellulose iti-viscosity mo te hanga, me te nui ake o te taapiri.
4 Te hototahitanga o te stucco
Mo te nui o te kumete maroke, he pai ake te whakaputa i te nui ake o te nui o te kumete maku, ka taea ma te taapiri i nga mirumiru wai me te hau.Engari he nui rawa te nui o te wai me te mirumiru hau
