Hydroxypropyl methyl cellulose me te ōwehenga ciment

He aha te HPMC hpmc hydroxypropyl cellulose me te ōwehenga ciment?

Ko te paru paruru i te parekura, ko ona ahuatanga e whakawhirinaki ana ki te taumaha kupenga e whai ake nei: raima.hydroxypropyl methyl cellulose7-9, Siken Carbide paura 40-45, te konupora waikawa paura 10-20, ka maroke te paura kaha o te taone nui 40-25, te konumohe i whakarereketia te 2000-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6-6- 7 Ko te miihini whakairo parewai i te parekura o tenei hua, he kaha ki te whakakii i te wera, he kaha te kaha ki te pakitara, te makuku o te taiao, te makuku o te makuku, te aukati i te makuku. I tenei ra ka korerohia e maatau te ahua o te rongoa o te hydroxypropyl cellulose Aquous te otinga katoa o te waa? Kia ako tonu tatou.

1 2. Ko te teitei o te pāmahana whakawhiti karaihe, ko te nui o te taumaha o te waikawa whanaunga, ko te ahua o te otinga he teitei ake; 3. Ko te teitei o te ihirangi o te Eter Cellulose, ko te teitei o te kohinga e tika ana kia aro ki te whakauru i te whakauru, me te pa ki nga ahuatanga o te raima CEMING; 4 I tua atu, ko te hua matotoru tonu te rereke i runga i te nui o te wai e whakamahia ana mo te raima epoxy.

Ko te whakamaarotanga o te rongoa mo te kohinga o te paparanga, engari he nui rawa te ahua o te maatauranga o te papa. Mo etahi whakarereketanga-a-taangata-a-tinana me te kaha o te wai, te ahua o te ahua o te cellulose ether ka tohua kia iti ake.

Ko te otinga a te Cellulose Ether he tinana pseudoplastic, i te mutunga o te kitenga o te reinga kutikuti he nui ake, he iti ake te tirohanga.

Na reira, ko te moni ko: te taapiri o te paruru o waho, engari ka nui ake te otinga o te miihini o te ao hou, ka puta te otinga kukupa.

Ko te pupuri i te wai mai i te hydroxypropyl methyl cellulise tetahi o nga waahanga nui o te celluloxypropy methyl cellulose. Ko te reanga o te whakahekenga o te kiko wai i roto i te papanga whakaranu me nga hua kua pa ki te raima e pa ana ki te pāmahana hau, te pāmahana me te reanga o te pehanga. Na reira, i roto i nga waa rereke, me te hydroxypropyl methyl cellulose te nui o te whaihua o te wai hua he rereke.

I roto i te katoa, ko te teitei o te tirohanga o te hydroxypropyl cellulise, ko te mea pai o te pupuri wai, engari ko te kino o te tirohanga ki te 100,000 MPA. s. I te wa e nui ake ai te ahua o te huringa o te hydroxypropy methyl cellulose 100,000, ka tino pai ake te utu o te wai-wai ma te whakapiki i te nui o te hydroxypropyl cellulose.

I roto i nga tikanga hangahanga, ka taea te whakatika i te hua pupuri wai o te slurry ma te whakatika i te nui o te cellloxypropy cellulose. Ka taea e nga hua o te hydroxypropyl methyose nga hua raupaparorohiko raupaparorohiko hei whakaoti i te raru o te pupuri wai i raro i te pāmahana tiketike. I roto i te waa o te pāmahana nui tonu, otira i nga waahi wera me te hoha, me te hanga i te pouaka whakaata, te kounga teitei o te hydroxypropyl methyl e hiahiatia ana hei whakawhanake i te pupuri wai.

Te kounga teitei o te hydroxypropyl cellulose, he pai te toenga, ko te miihini o te hauota o te mamati me te wai o te mamati i puta mai i te wai Whakatakotoria, te pupuri i te wai nui.

Ko te kounga nui o te hydroxypropyl cellulose ka uru ki nga whenua whakaranu me nga raima totika, me te whakakoi i te kaha o te raukaha i te kaha. I roto i te tukanga hanga raumati nui rawa atu, kia eke ki te tohutao mo te kohinga me te kounga o te hydroxypropy, ka whakakotahihia e te hunga uaua. I te heke o te pāmahana, ko te nui o te hydroxypropyl cellulose ka taea te whakaheke me te whakatutukitanga o te kaupapa mo te wahanga wai.

Mena kaore i te taapiri te Eter, ko te chromatolo ka maroke, kaore e taea te whakakii i te raima i roto i te huarahi noa, kaore e taea te whakaheke i te raima ciment me te pai ake. I te wa ano, ko te taapiri o te cellulose Ether e hanga ana i te paruru i te waatea, me te ngawari, ka whakapai ake i te kaha kōkiri i te hononga CIMING.

1, te rahi matūriki hydroxypropyl

Ko te rahi o te matūriki o te cellulose e patu ana i tona ngoikoretanga. Ko te Cellul Cellulose Ether, ko te tere ake o tana reeti i roto i te wai me te teitei ake o ona ahuatanga-pupuri wai. Na reira, ko te rahinga matūriki o te cellulose Ether kia whakauruhia ki te tirotiro i tetahi o ona ahuatanga. I roto i te rahi, te rahi o te matūriki celluluse o te 80 mesh e pa ana ki.

2, hydroxypropyl methyl cellulose maroke kaore he reanga nui

Maeneene maroke Kaore he reiti o te tipu, e tohu ana i etahi pāmahana maroke tenher, ko te ngaro o te kounga matū, ko te ngaro o te kounga matū mo te tauira kounga o te hanganga. Mo te kounga o te cellulose eter i te maroke kaore he tere o te reanga, ka whakaiti i nga waahanga e tika ana ki te whakamahi i nga kamupene o raro, engari me whakapai ake ano hoki te utu hoko. I te nuinga o te waa ko te waa maroke maroke kaore i te neke atu i te 5.0%.

3, hydroxypropyll methyl cellulose pāhare pāporo

Mo etahi kohinga o te Eter i roto i nga ihirangi pungarehu he tiketike rawa, ka whakaiti i te eter Cellulose i roto i nga waahanga e whai kiko ana, ko te konupora tonu o te whakamahi i nga waahanga o raro.

4, hydroxypropyl methyl cellulose viscicondy

Ko te Methrose Cellulose Cellulose Te Waehere Waihoki me te matotoru te tohu hei taapiri i te raima raima Cellulose me te whakauru.

5, hydroxypropyl methyl cellulose ph uara ph

Ko te tirohanga o te hydroxypropyl o nga hua methyl cellulose e whakaheke tere ana i te pāmahana teitei, i muri i te rokiroki mo te wa roa, ina koa me iti te uara pH. I te nuinga o te wa e whakahaerehia ana te kāwai uara pH o te ether i te 5-9.

6. Whakawhitinga o te cellloxypropyl methyl cellulose

Ko nga painga me nga ngoikoretanga o te whakawhiti i te cellroxypropyl cellulose e pa ana ki te tino paanga o tana whakamahinga ki te hanga taonga. Ko nga mea tuatahi e kino ana ki te whakawhiti i te cellulose eter1) te kounga o nga rauemi mata; (2) te tino hua o te paheketanga; (3) Te tukatuka i te hangarau hangarau; (4) Te whakareri whakarewa raupaparorohiko; (5) te tino hua o te zhonghe.

E ai ki te tino tono, ko te whakawhiti o te ether cellulose kaua e iti iho i te 80%.

7, hydroxypropyl methyl cellulose i whakapaetia

Ko te Cellurose te hydroxypropyl methyl i roto i nga waahanga cell. Whakamahia ai te pāmahana ki te whakawa i te momo me te tohu o te eter cellulose, me te tohu o te whakakapinga cellulose e pa ana.

8. Hei taapiri, ko te tote me te toenga ka kino ano te mate o te kāpia. I te wa ka ara ake te pāmahana o te otinga o te Fix, ka pakaru te wai o te Polymer i te wai, me te whakamahana o te otinga waiu. A, no te tae te wāhi piri, ka maroke te polymer, a ka whakaputaina te piri. Na reira, ko te pāmahana whakahaere o nga mema raima kei te nuinga o te pāmahana o mua. I raro i tenei paerewa, ko te raro o te pāmahana, te teitei o te tirohanga, me te nui ake o te tino hua o te whakakitenga me te pupuri i te wai.
