Te tere pupuri wai o HPMC 200000 pokey hydroxypropyl methyl cellulose

Ko te mahi nui o te wai-wairewahydroxypropyl methyl cellulose HPMCi roto i te kumete he mea nui i roto i nga waahanga e toru, tetahi he pai te pupuri i te wai kaha ngaio, e rua ko te kino ki te pokey me te compressibility o te kumete, e toru ko te taunekeneke ki te sima. Ko te pupuri i te wai ngoikore o te kumete i roto i te tukanga katoa o te kawe he ngawari ki te wehe i te rere o te wai, ka horahia ki runga i te mata o nga mea maiengi, ko te nuinga o te wai he ngawari ki te keri, te whakaputa i nga ahuatanga rereke o te kumete, te paru ki raro i te kino o te paru. te whakakotahitanga noa me nga waahanga iti o nga rauemi mata i waenganui o te hononga me te whakaiti i te kaha o te pupuhi o te pakitara masonry. Ko te pupuri i te wai o te kumete ka whakamaramatia e te stratification.
Ko te nui ake o te pokey ohydroxypropyl methyl celluloseKo te HPMC, ko te pai ake o te mahi pupuri wai, ko te pai ake te pokey o te wairewa wai polymer. Ko te roa me te ahua o te mekameka ngota ka whakawhirinaki ano ki te papatipu ngota ngota o te polymer (te pāmahana whakawhiti karaihe). Ko te maha o nga roopu mahi ka pa ki te awhe pokey.
Hydroxypropyl methyl cellulose HPMC ake te mahi pupuri wai mai i te hydroxypropyl methyl cellulose ake te memehatanga me te whaipainga wai. E mohiotia ana ko te cellulose he kore e rewa ki te wai na te mea he ahua teitei te hanga tioata, ahakoa kei roto i te mekameka ngota o te muka he maha nga roopu OH tino waikore.
Ko nga here kovalent tino kaha me nga topa van der Waals i waenga i nga hanganga ngota e kore e taea te utu ma te kaha whakamakuku o nga roopu methyl anake. Na reira, ka taea te rewa i roto i te wai anake. Ina whakaurua mai nga ngota ngota whakakapi, ehara i te mea ko nga ngota ngota whakakapi anake ka whakangaro i te mekameka hauwai, engari ko nga here kovalent i roto i te mekameka hauwai ka whakangaromia e nga ngota ngota whakakapi i nga poro i nga mekameka tata. Ka nui ake te whakakapinga, ka nui ake te mokowhiti ngota. Ko te nui ake o te whaipainga hei wawahi i nga here kovalent. I te wa e roha tonu ana te kurupae muka, ka uru mai te wairewa wai, ka rewa te wairewa te hydroxypropyl methyl cellulose ki te wai, ka puta he wairewa wai tino keokeo.
I te pikinga o te pāmahana ambient, ka iti ake te whai hua o te whakamakuku o te polymer, ka peia te wai i waenganui o te mekameka. Ka nui te wai ka tangohia, ka whakaemi haere te hanganga ngota, ka puta he kupenga ahu-toru o nga kopa ka taea te totoro. Ko te pokey, te inenga, te rahi matūriki me te pāmahana tono o te hydroxypropyl methyl cellulose ko nga mea e kino ai te mahi pupuri wai o te kumete.
Hydroxypropyl methyl cellulose viscosity kua wehea ki: viscosity 100,000, viscosity 150,000, viscosity 200,000.
Me pehea te whiriwhiri hydroxypropyl methyl cellulose?
100,000 pokey hydroxypropyl methyl cellulose ka taea te whakamahi hei paura putty pakitara o roto. Kaihere taera. Kaipupuri. Moata raima here. Te pakari o nga rauemi grouting kore whakaheke.
He teitei ake te whakatakotoranga moata moata moata whakaahuru, he 150 mano hydroxypropyl methyl cellulose ranei 200 mano hydroxypropyl methyl cellulose. Ki te whiriwhiri i nga hua hou e 100 mano te pokey, whakaputa rere ki te whakairi i tetahi ahuatanga tino ngawari.
Ko te mahi tino nui o te methyl cellulose ko te pupuri wai, ka whai i te whakapakeke. Kia hoha ki te paura o te tamaiti i roto i te pakitara o roto, mena he pai ake te rewa o te wai me te iti o te pokey (70000-80000), ka taea tonu te tono. Ka nui ake te pokey ki te 100,000, karekau he kino ki te pupuri wai. I roto i te hanga me te hanga o te paura putty pakitara o roto, kaore he take ki te whiriwhiri i te 200,000 viscosity. Na te mea he nui rawa te pokey, he uaua ki te raraku me te rakuraku i nga rahinga nui.

Ko te Hydroxypropyl methyl cellulose e whakamahi ana i te 100,000 viscosity.
1. Kaupapa Hangaia te kumete raima moata puranga putty moata.
Ko te wairewa teitei ka taea e te raima te whakamaaramatanga o te raima, ka piki tonu te kaha o te piri. Waihoki, ko te kaha o te kaha me te kaha o te tapahi laser ka taea te whakapai ake, ka pai ake te painga o te hanga whare, te whakapai ake i te pai.
2. I roto taiepa putty paura makuku ātete.
I roto i te putty, moisturizing, hononga, whakahinuhinu he mea tino nui, ki te aukati i te nui o te wai i puta mai i nga kapiti me nga tikanga maroke ka pai ake te hononga o te paura putty pakitara o roto, whakaitihia te rere o te iri ahuatanga i roto i te hanga, te hanga miihini maeneene.
3. Plaster of Paris paraihe raupapa hua.
I roto i te raima o nga hua raupapa Paris, kei a ia nga tino paanga o te pupuri wai, te matotoru me te makuku. Ko te penei, he paanga o te tautuhinga tuatahi, ka taea te whakanui ake i te waa hanga me te whakatutuki i nga raru o te pakaru me te kaha o te kaha o te kaha o te mahi hangahanga.
4. Puti parewai.
Ka rite ki te tono nui o demulsifier, ka taea e te whakapai ake i te kaha tensile me te tapahi taiaho compressive kaha, te whakapai ake i te paninga mata, te whakapai ake i te adhesion me te hononga kaha compressive.
5. Te whakapiri tira uku.
Ko nga taera papa whakarewa wai teitei me nga turanga ahumahi kaore e hiahiatia kia makuku, kia makuku ranei i mua, ka tino pai ake te kaha o te hononga. He roa te wa hanga, he ngawari me te kakahu, ka penapena te wa me te whakapau kaha ki te hanga. I tua atu, he mea whakahinuhinu te kounga teitei.

6. Kaihoko. Te hiri o te awaawa.
HPMC muka ki te adhesion o te kounga teitei, iti te whakaheke me te teitei kakahu ātete, te tiaki o nga rauemi mata taketake i te whakangaromanga o taputapu ahumahi, ki te ārai i te urutomo o kaupapa hanga katoa.
7. Dc nga mea maamaa.
Ko te kaha o te hono maenee ka whakarite i te punaha tohanga kounga teitei o te raima me te kaha ki te whakataurite i a koe ano o te sima, ka whakatika i te reiti pupuri makuku kia tere ai te pakari me te whakaiti i te pakaru me te kati.
8. Te peita o te pakitara peita a-ahumahi.
I roto i te ahumahi tukatuka whakakikorua me te ahumahi whakangao, ka taea te whakamahi i te methylpropyl methyl cellulose hei kaihoko hanga kiriata, demulsifier, demulsifier me te whakapiri, kia pai ake ai te kakahu o te kiriata, te pai o te mahi whakakikorua, te piri me te mata o te pH he utu. whakapai ake. He pai hoki nga hua e tumanakohia ana ina konatunatua ki nga whakarewa waro. He nui te pupuri makuku me te mahi peita o te kounga teitei.

Hydroxypropyl methyl cellulose 1500000 viscosity.
I waenganui o te 100,000 viscosity me te 200,000 viscosity, 150,000 viscosity tata ki te 100,000 viscosity.

Hydroxypropyl methyl cellulose 200,000 whakamahi.
I roto i nga rauemi hanga, ina koa ko te whakamahi i te kumete paparanga parakore, ko te mea nui ko te whakapai ake i te whakakotahitanga, te whakarei ake i te kaha o te kaha, kia ngawari ake te whakapiri i te kumete raima, te whakapai ake i te pai. I tua atu, he hua anti-vertical liquidity. Ka taea e te mahi makuku teitei te whakaroa i te wa rere o te kumete raima, te whakapai ake i te aukati pakaru me te punga, te whakapai ake i te kounga o te mata, te whakapai ake i te piri.
(1) Ko te pupuri i te wai o te methyl cellulose e whakawhirinaki ana ki te nui o te taapiri, te pokey, te pai o te matūriki me te tere memeha. Ko te tikanga, he nui te nui o te taapiri, he iti te pai, he nui te pokey, he tiketike te reeti pupuri wai, i roto i enei ko te nui o te taapiri he nui te awe ki te reeti pupuri wai, ko te pokey me te reeti pupuri wai kaore i raro. nui atu i te hononga, ko te reiti memehatanga ka whakawhirinaki ki te tohu whakarerekētanga o te mata me te pai o te matūriki o te matūriki cellulose. Methyl cellulose me te hydroxypropyl methyl cellulose kei runga ake nei he maha nga etera cellulose he nui ake te reeti pupuri wai.
