Hydroxypropyl methylcellulose mo te rehu taiepa!

Ko nga hua Hydroxypropyl methylcellulose mo te hanga e whakamahia nuitia ana hei whakapai ake i te mahi o nga rawa hanga waipēhi, penei i te ciment me te gypsum.I roto i nga moata ciment, ka pai ake te pupuri i te wai, te whakaroa i te whakatikatika me te wa tuwhera, me te whakaiti i te whakaheke.

a.Te pupuri wai

Ko te Hydroxypropyl methylcellulose mo te hanga ka aukati i te makuku kia kore e uru ki te pakitara.Ka noho te nui o te wai ki roto i te kumete, kia roa ake ai te wa whakamakuku o te sima.Ko te pupuri wai he rite ki te pokey o te wairewa eter cellulose i roto i te kumete.Ko te teitei ake o te pokey, ko te pai ake o te pupuri wai.Kia piki ake nga ngota ngota wai, ka heke te pupuri wai.Na te mea mo te rite tonu o te otinga hydroxypropyl methylcellulose hanga-motuhake, ko te pikinga o te wai te tikanga he heke te pokey.Ko te whakapai ake i te pupuri wai ka roa ake te wa whakamaroke o te kumete e hangaia ana.

b.Whakapai ake te hanga

Ko te whakamahinga o te hydroxypropyl methylcellulose HPMC ka taea te whakapai ake i te hanga o te kumete.

c.Te kaha whakahinuhinu

Ka mahi nga apiha whakauru hau katoa hei makuku ma te whakaheke i te awangawanga o te mata me te awhina i nga whaina o te kumete kia marara ina konatunatua ki te wai.

d.Anti-sagging

Ko te tikanga o te kumete-atete pai ki te whakauru ki roto i nga paparanga matotoru karekau he kino o te totohu, te rere whakararo ranei.Ka taea te whakapai ake i te aukati sag ma te hanga-motuhake hydroxypropyl methylcellulose.Ko te hydroxypropyl methylcellulose hanga-motuhake i hangaia e Shandong Chuangyao Company ka taea te whakarato i nga taonga anti-sagging pai ake o te kumete.

e.Ihirangi mirumiru

Ko te nui o te mirumiru o te hau ka pai ake te tuku kumete me te kaha mahi, ka whakaiti i te hanga kapiti.Ka whakahekehia ano te uara kaha, ka puta he ahuatanga "whakarereke".Ko te ihirangi mirumiru o te rangi ka whakawhirinaki ki te wa whakakorikori.

Nga painga o te hydroxypropyl methylcellulose i roto i te hanga rauemi hanga:

Ko te Hydroxypropyl methylcellulose ona ahuatanga motuhake mo te whakamahi i nga rawa hanga whare, mai i te whakaranu ki te whakamararatanga ki te hanga, penei:

Hiato me te whirihoranga:

1. He ngawari te whakauru ki te tauira paura maroke.

2. Kei a ia nga ahuatanga o te marara wai matao.

3. Whakatarewa tika i nga matūriki totoka, kia maeneene ai te ranunga, kia rite tonu.

Te marara me te ranu:

1. Ko te tauira whakakotahi maroke kei roto te hydroxypropyl methylcellulose ka ngawari te whakauru ki te wai.

2. Hohoro te tiki i te riterite e hiahiatia ana.

3. He tere ake te rewa o te cellulose ether me te kore he kapia.

Hanganga ipurangi:

1. Whakapai ake i te whakahinuhinu me te kirihou hei whakarei ake i te machinability me te hanga hua ake watea me te tere.

2. Whakanuia nga ahuatanga pupuri wai me te whakaroa i te wa mahi.

3. Ka awhina ki te aukati i te rere poutū o te kumete, te kumete me nga taera.Whakaroahia te wa whakamahana me te whakapai ake i te pai o te mahi.

Kua oti te mahi me te ahua:

1. Whakapai ake i te kaha honohono o nga taapiri taera.

2. Whakanuia te whakahekenga anti-kapiti me te kaha anti-ngatata o te moata me te whakakii i te papa.

3. Whakapai ake i te ihirangi hau i roto i te kumete me te tino whakaiti i te tupono ka pakaru.

4. Whakapai ake i te ahua o nga hua kua oti.

5. Ka taea e ia te whakarei ake i te aukati rere poutū o te whakapiri tira.

Ko te Hydroxypropyl methylcellulose (HPMC) he etera cellulose kore-ionic i hangaia mai i te miro parakore na roto i te raupapa o nga tukanga matū.Ko te Hydroxypropylmethylcellulose (HPMC) he paura ma kore kakara, kore reka, kore-paitini ka taea te rewa ki te wai matao hei hanga i te wairewa puataata.Kei a ia nga ahuatanga o te whakapakeke, te here, te whakamarara, te whakaemulsifying, te hanga kiriata, te whakatārewa, te adsorbing, te gelling, te kaha o te mata, te pupuri i te makuku me te tiaki i te colloid.
