He aha te whakamahinga matua o te hydroxypropyl methylcellulose?
——Whakautu: Kei te whakamahia nuitia te HPMC i roto i nga taonga hanga, paninga, kapia waihanga, uku, rongoa, kai, kakano, ahuwhenua, whakapaipai, tupeka me etahi atu ahumahi. Ka taea te wehewehea te HPMC ki te tohu hangahanga, te karaehe kai me te karaehe rongoa e ai ki te kaupapa. I tenei wa, ko te nuinga o nga hua o te kaainga he tohu hanga. I roto i te hanganga hanga, ka whakamahia te paura putty i roto i te nui nui, mo te 90% e whakamahia ana mo te paura putty, ko te toenga ka whakamahia mo te moata ciment me te kopa.
Me pehea te wehewehe i te kounga o te HPMC ngawari me te ngawari?
——Whakautu: (1) Maama: Ahakoa kaore e taea e te ma te whakatau mena he ngawari te whakamahi i te HPMC, a mena ka taapirihia nga maaka ma i te wa o te mahi whakaputa, ka pa ki tona kounga. Engari, ko te nuinga o nga hua pai he pai te ma. (2) Pai: Ko te pai o te HPMC he 80 mesh me te 100 mesh, he iti ake te 120 mesh. Ko te nuinga o te HPMC i hangaia i Hebei he 80 mata. Ko te pai ake o te pai, ko te tikanga, ko te pai ake. (3) Whakawhiti marama: hoatu te hydroxypropyl methylcellulose (HPMC) ki roto i te wai kia hanga he colloid maramara, ka titiro ki tana whakawhiti marama. Ko te nui o te whakawhiti marama, ko te pai ake, e tohu ana he iti ake nga insolubles kei roto. . I te nuinga o te wa he pai te uruhanga o nga reactors poutū, he kino ake te kino o nga reactors whakapae, engari ehara i te mea he pai ake te kounga o nga reactors poutū i te pai o nga reactors whakapae, a ka whakatauhia te kounga hua e te maha o nga mea. (4) Te taumahatanga motuhake: Ko te nui ake o te taumahatanga motuhake, ko te taumaha ake ka pai ake. He nui te motuhake, te tikanga na te mea he tiketike te ihirangi o te roopu hydroxypropyl kei roto, he nui te ihirangi o te roopu hydroxypropyl, he pai ake te pupuri wai. (5) Te Weranga: Tangohia tetahi wahi iti o te tauira ka tahuna ki te ahi, ko te toenga ma he pungarehu. Ko te nui ake o nga mea ma, ko te kino o te kounga, me te mea kaore he toenga i roto i nga taonga parakore.
He aha te utu o te hydroxypropyl methylcellulose?
—–Whakautu; Ko te utu o te hydroxypropylmethyl e whakawhirinaki ana ki tona ma me te ihirangi pungarehu. Ko te teitei ake o te parakore, ko te iti o te pungarehu o te pungarehu, ko te utu teitei ake. Ki te kore, ko te iti ake o te ma, ko te nui o te pungarehu, ko te iti ake o te utu. Tone ki te 17,000 yuan mo ia tana. Ko te 17,000 yuan he hua parakore me te tata kore poke. Mena he nui ake te utu o te waeine i te 17,000 yuan, kua piki ake te hua o te kaihanga. He ngawari te kite mehemea he pai, he kino ranei te kounga i runga i te nui o te pungarehu i roto i te hydroxypropyl methylcellulose.
He aha te pokey o te hydroxypropyl methylcellulose e tika ana mo te paura putty me te kumete?
—–Whakautu; Ko te paura putty te tikanga 100,000 yuan, a ko te whakaritenga mo te kumete he teitei ake, me 150,000 yuan kia ngawari ki te whakamahi. I tua atu, ko te mahi tino nui o te hydroxypropyl methylcellulose ko te pupuri wai, ka whai i te whakapakeke. I roto i te paura putty, i te mea he pai te pupuri wai me te iti o te pokey (70,000-80,000), ka taea hoki. Ko te tikanga, he teitei ake te viscosity i raro i te 100,000, a he pai ake te pupuri i te wai whanaunga. Ka nui ake te viscosity ki te 100,000, ka whai hua te viscosity ki te pupuri wai Kaore i te nui te paanga.
