Rā Whakairi:3,Hurae,2023

Hydroxypropyl methyl cellulose(hpmc)Ko te tikanga ka whakamahia i roto i te paura putty me te 100000 viscosity, i te mea he nui nga whakaritenga mo te moata mo te viscosity me te whiriwhiri me te 150000 viscosity mo te whakamahi pai ake. Ko te mahi tino nui ohydroxypropyl methyl celluloseko te pupuri i te wai, ka whai i te whakamatotoru. Na reira, i roto i te paura putty, i te mea ka tae te pupuri wai me te iti iho te pokey, ka taea hoki. Ko te tikanga, ko te teitei ake o te pokey, ko te pai ake o te pupuri wai. Heoi, ka nui ake te pokey 100000, karekau he mea nui te paanga o te pokey ki te pupuri wai.

Jufu Building Material GradeHydroxypropyl Methyl CelluloseKa wehewehea e te Viscosity, ka wehewehea ki nga momo e whai ake nei:

1. Iti pokey: 400 pokey cellulose, te nuinga whakamahia mō te kumete whakaōrite whaiaro. Te pokey iti, te rere pai, a, i muri i te taapiri, ka whakahaerehia e ia te pupuri i te wai mata. Kaore e kitea te toto, he iti te whakaheke, ka iti te pakaru. Ka taea hoki te aukati i te parataiao, te whakarei ake i te rere me te papu.
2. Waenga ki te iti viscosity: 20000 ki 50000 viscosity cellulose, te nuinga whakamahia mō hua gypsum me whakakī tahi. He iti te pokey, he pai te pupuri wai, he pai te mahi, he iti te taapiri wai,
3. Pokey Waenga: 75000-100000 viscosity cellulose, te nuinga whakamahia mo te putty taiepa o roto me waho. He pai te pokey, he pai te pupuri i te wai, me te pai o te papanga hanga.
4. Te pokey teitei: 150000 ki te 200000 yuan, te nuinga whakamahia mo te polystyrene matūriki matūriki kumete moata paura rauemi, vitrified moroiti pirepire kumete kiriweti ki te pokey teitei me te pupuri wai. Ko te moata ehara i te mea ngawari ki te taka me te whakairi, te whakapai ake i te hanga.
Ko te tikanga, ko te teitei ake o te pokey, ko te pai ake o te pupuri wai. Na reira, he maha nga kaihoko ka whiriwhiri ki te whakamahi i te cellulose viscosity medium (75000-100000) hei utu mo te cellulose viscosity low medium (20000-50000) hei whakaiti i te nui o te taapiri me te utu whakahaere.
Te pokey oHPMChe taurite ki te pāmahana, ara, ka piki te pokey me te hekenga o te pāmahana. Ko te pokey o te hua te tikanga ko tana otinga 2% kei te mahana o te 20 nga nekehanga Celsius, a he tika nga hua whakamatautau.
I roto i nga tono motuhake, me aro ki nga waahi he nui nga rereketanga o te pāmahana i waenga i te raumati me te takurua, me te kaha ki te whakamahi i te pokey iti i te takurua. Ki te kore, ki te iti te pokey, ka piki ake te pokey o te cellulose, ka taumaha hoki nga rakuraku.
