Te pokey iti: Ko te 400 te nuinga e whakamahia ana mo te kumete whakamaarama whaiaro, engari he mea kawemai.
Take: He iti te pokey, he iti te pupuri i te wai, engari he pai nga ahuatanga o te whakataurite, he nui te kiato moata.
Waenga me te iti pokey: 20000-40000 te nuinga whakamahia mo te whakapiri tira, kaihoko caulking, moata anti-kapiti, waiariki moata herenga here, etc.
Take: He pai te mahi, he iti ake te wai taapiri, he nui te kiato kumete.
1. He aha nga tino whakamahinga o te hydroxypropyl methylcellulose (HPMC)?
——A: Kei te whakamahia nuitia te HPMC ki nga taonga hanga whare, paninga, kapia waihanga, karaima, rongoa, kai, kakano, ahuwhenua, whakapaipai, tupeka me etahi atu ahumahi.Ka taea te wehewehea te HPMC ki: te tohu hanga, te karaehe kai me te tohu rongoa e ai ki te whakamahinga.I tenei wa, ko te nuinga o nga hua o te whare he tohu hanga.I roto i te kohinga hanga, ka whakamahia te paura putty i roto i te nui nui, mo te 90% e whakamahia ana mo te paura putty, a ko te toenga ka whakamahia mo te raima ciment me te kopa.
2. E hia nga momo hydroxypropyl methylcellulose (HPMC) kei reira?He aha o raatau whakamahinga?
——A: Ka taea te wehea te HPMC ki te momo inamata me te momo rewa wera.Ka marara nga hua inamata ki te wai matao ka ngaro ki te wai.Karekau he pokey o te wai i tenei wa na te mea ka marara noa te HPMC ki roto i te wai kaore i tino memeha.I muri tata ki te 2 meneti, ka piki haere te pokey o te wai, ka puta mai he colloid viscous marama.Ka tere marara nga hua wera-wairewa i roto i te wai wera ka ngaro i roto i te wai wera ina tutaki ki te wai matao.Ka heke te pāmahana ki tetahi pāmahana (ko te hua o ta tatou kamupene he 65 nga nekehanga Celsius), ka ata puta te pokey tae noa ki te hanga i tetahi colloid puataata.Ko te momo whakarewa wera ka taea anake te whakamahi mo te paura putty me te moata.I roto i te kapia wai me te peita, ka pupuhi ka kore e taea te whakamahi.Ko te momo tata he whanui ake nga tono.Ka taea te whakamahi mo te paura putty, te kumete, te kapia wai, me te peita me te kore he aukati.
3. He aha nga tikanga whakarewa o te hydroxypropyl methylcellulose (HPMC)?
——Whakautu: Tikanga wetewete wai wera: I te mea he koretake te HPMC ki te wai wera, ka taea te marara o te HPMC ki te wai wera i te wa tuatahi ka rewa tere i muri i te whakamatao.E rua nga tikanga angamaheni e whakaahuatia ana i raro nei:
1) Kuhua te nui o te wai wera ki roto i te ipu ka whakamahana ki te 70 ℃.Taapirihia te hydroxypropyl methylcellulose me te whakaoho puhoi.I te tuatahi ka maanu te HPMC ki runga i te mata wai, katahi ka hangai he slurry, ka whakamatao me te whakakorikori.
2).Tāpirihia te 1/3, te 2/3 rānei o te nui o te wai e hiahiatia ana ki roto i te ipu, whakamahana ki te 70°C, whakamararatia te HPMC kia rite ki te tikanga i roto i te 1), ka whakarite i te slurry wai wera;kātahi ka tāpirihia te toenga o te wai matao ki te slurry wai wera.slurry ki te wai, whakaohokia me te whakamatao i te ranunga.
Te tikanga whakaranu i te paura: Whakaranuhia te paura HPMC me te nui o etahi atu matū paura, uru pai ki te whakaranu, katahi ka tapirihia he wai kia memeha.I tenei wa, ka taea te whakakore i te HPMC ka kore e piri tahi, no te mea he iti noa te HPMC i ia wahanga.Koki iti.Ka memeha tonu te paura ina pa ana ki te wai.——Ka mahia tenei tikanga e nga kaihanga paura putty me te kumete.Ko te Hydroxypropyl methylcellulose (HPMC) e whakamahia ana hei whakakaha me te pupuri wai i roto i te kumete paura putty.
4. Me pehea te whakatau i te kounga o te hydroxypropyl methylcellulose (HPMC) ngawari me te mohio?
——Whakautu: (1) Maama: Ahakoa kaore te ma e whakatau mena he ngawari te whakamahi a HPMC, mena ka taapirihia nga rama 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, me te 120 mesh he iti ake.Ko te nuinga o te HPMC i hangaia i Hebei he 80 mata.Ko te pai ake ko te pai ake.(3) Whakawhiti marama: Kuhua te hydroxypropyl methylcellulose (HPMC) ki roto i te wai hei hanga i te colloid maramara, me te tirotiro i tana whakawhiti marama.Ko te teitei ake o te whakawhiti marama, ko te pai ake, e tohu ana he iti ake nga matū korekore o roto.Ko te kaha o te hau o nga reactors poutū he pai ake i tera o nga reactors whakapae, engari kaore e taea te kii he pai ake te kounga o nga reactors poutū i tera o nga reactors whakapae.He maha nga mea e whakatau ana i te kounga o nga hua.(4) Te taumaha motuhake: Ko te nui ake o te taumaha motuhake me te taumaha ake, ka pai ake.Ko te taumahatanga motuhake na te nui o te ihirangi hydroxypropyl kei roto.Ko te teitei o te ihirangi hydroxypropyl, ko te pai ake o te pupuri wai.
5. He aha te inenga o te hydroxypropyl methylcellulose (HPMC) i roto i te paura putty?
——Whakautu: Ko te inenga o te HPMC i roto i nga tono tuuturu he rereke i runga i te ahuarangi, te pāmahana, te kounga konupūmā pungarehu o te rohe, me te tauira whakauru.te paura me te "kounga e hiahiatia ana e te kaihoko".Ko te tikanga, kei waenga i te 4kg ki te 5kg.Hei tauira, ko te nuinga o te paura putty i Beijing he 5 kg;Ko te nuinga o te paura putty i Guizhou he 5 kg i te raumati me te 4.5 kg i te takurua;
6. He aha te pokey tika o te hydroxypropyl methylcellulose (HPMC)?
——Whakahoki: Ko te paura Putty te utu 100,000 yuan, me te moata me nui ake, no reira 150,000 yuan te nui.A ko te mahi tino nui o te HPMC ko te pupuri wai, ka whai muri 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 pai.O te akoranga, te teitei te pokey, te pai te pupuri wai whanaunga.Ina neke ake te viscosity ki te 100,000, he iti te paanga o te pokey ki te pupuri wai.
7. He aha nga tohu hangarau matua o te hydroxypropyl methylcellulose (HPMC)?
——A: Hydroxypropyl content and viscosity, te nuinga o nga kaiwhakamahi kei te awangawanga mo enei tohu e rua.Ko te teitei o te ihirangi hydroxypropyl, ko te pai ake o te pupuri wai.Ma te kaha o te pokey, he pai ake te pupuri i te wai (kaore i te tino) pai ake, me te nui o te pokey, he pai ake te whakamahi i roto i te kumete ciment.
8. He aha nga mea matua o te hydroxypropyl methylcellulose (HPMC)?
—— A: Ko nga rauemi mata matua o te hydroxypropyl methylcellulose (HPMC): miro parakore, methyl chloride, propylene oxide, etahi atu rauemi mata ko te houra caustic, te waikawa, te toluene, te waipiro isopropyl, etc.
9. He aha te mahi matua a te HPMC ki te tono paura putty?He pānga matū kei a ia?
——Whakautu: E toru nga mahi nui a te HPMC mo te whakamatotoru, te pupuri wai me te hanga i te paura putty.Matotoru: Ka taea e te Cellulose te whakakaha i te whakatarewatanga, ka mau i te ahua o te otinga me te aukati i te heke.Te pupuri wai: Kia ata whakamaroke te paura putty ka awhina i te hohenga o te konupūmā hina i raro i te mahi a te wai.Hanganga: He whakahinuhinu te whakahinuhinu o te Cellulose ka taea e te paura putty te mahi pai.Karekau a HPMC e uru ki roto i nga tauhohenga matū, he mahi awhina anake.Ina tapirihia te paura putty ki te wai ka pa ki te pakitara, ka puta he tauhohenga matū.Ka hangaia he matū hou, ka tangohia te paura putty i runga i te pakitara mai i te pakitara ka huri hei paura i mua i te whakamahi.Kare e mahi na te mea kua hanga he matū hou (konupora warowaiha).) ki runga.Ko nga waahanga matua o te paura konupūmā hina ko: he ranunga o Ca(OH)2, CaO me te iti o te CaCO3, CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O Gray calcium ka memeha i roto i te wai me te hau CO2 I raro i te mahi a te konupūmā warowaihā, ka pupuri noa te HPMC i te wai me te awhina i te konupūmā hina kia pai ake te mahi, kaore hoki e uru ki tetahi tauhohenga ake.
10. Ko te HPMC he cellulose ether kore-ionic, na he aha te mea kore-katote?
A: E ai ki nga korero a te reimana, ko nga katote kore he matū karekau e katote i roto i te wai.Ko te katotetanga ko te tukanga e wehe ai nga electrolytes ki roto i nga katote e nuku noa ana i roto i etahi whakarewa (hei tauira, te wai, te waipiro).Hei tauira, te konutai pūhaumāota (NaCl), te tote e pau ana ia rā, ka memeha ki te wai, ka katote, ka whakaputa i nga katote konutai (Na+) me nga katote konutai (Na+) me nga katote hauota (Cl).Arā, ka tukuna te HPMC ki roto i te wai, karekau e wehe ki roto ki nga katote katoo, engari kei te noho i roto i te ahua ngota.
