Ndeipi basa reHPMC mukongiri?

HydroxyPropyl methylcellose (HPMC) chikamu chakasikwa chinowanzoshandiswa mune yekuvaka indasitiri, kunyanya mukugadzirwa kwe kongiri. Basa rayo muongiri rinoita rakawanda, rakakanganisa zvese zvekuita kwemidziyo uye maitiro. Inotorwa kubva ku cellulose, iyi compound ine zvimiro zvakasarudzika zvinobatsira kuvandudza basa rekushanda, kusimba uye hunhu hwese hwezvivakwa zvekongiri.

1. Nhanganyaya kuHPMC:
1.1 makemikari chimiro:
Hydroxypropylmethylcylosellose ndeye Synthetic Polymer inotorwa kubva kuCellulose, polymer yakasikwa inowanikwa mumasero emasero. Chemical chimiro cheHPMC chine cellulose maketani akabatanidzwa ne methyl uye hydroxyprupropyl mapoka. Zviitiko zvevaidzipa izvi zvinogona kuchinjirwa kushandura zvivakwa zveHPMC uye nekuita kwayo mukokiri.

1.2 Zvivakwa zvemuviri:
HPMC ipurusi remvura rakazara nemvura ine midziyo yakanaka kwazvo-inoumba. Paunoparadzirwa mumvura, inoumba firimu rakatetepa rinobatsira kushandura iyo rheological uye michina yezvivakwa zvekongiri. Iyo firimu ine zvakare zvivakwa zvemvura, zvichidzivirira kurasikirwa kwakanyanya kwemvura mumatanho ekutanga ekuporesa kongiri.

2. Chikanganiso pakubata:
2.1 Kuchengeta mvura:
Imwe yemabasa ekutanga eHPMC mukongiri ndeye kugona kwayo kuchengetedza mvura. Semunhu hydrophilic polymer, hpmc inoumba firimu rakatetepa rakatenderedza nzvimbo dzechikamu, kudzora kubuda kwemvura panguva yekugadzika uye kuporesa matanho. Izvi zvinowedzera kushanda kweiyo kongiri yemusanganiswa, kubvumira kukanganisa kwakanaka uye kuiswa.

2.2 Kuvandudza Rheology:
HPMC inoita se rheology modifier, inokanganisa kuyerera uye deformation maitiro ekongiri. Nekugadzirisa huwandu hweHPMC, iyo kongiri musanganiswa inogona kuve yakagadziriswa kuti izadzise iyo yaunoda kusawirirana pasina kukanganisa zvimwe zvivakwa. Izvi zvinonyanya kukosha mukushandisa zvinosanganisira kupomba kana kudururira kongiri.

3 .comct pane kusimba:
3.1 Deredza kuwanda kwekupinda:
Kuwedzera HPMC kuenda kuConcrete Mixes inobatsira kuderedza kufarirwa kwezvinyorwa. Iyo firimu-inogadzira nzvimbo yeHPMC inoumba chipinganidzo chinokonzeresa kufamba kwemvura uye zvinokonzeresa zvinhu, nekudaro zvichikura kugadzika kwechimiro chekongiri nekuderedza njodzi yekurwiswa kwemakemikari uye kurwiswa kwesimbi.

3.2 Kusimudzira Freeze-Thaw Kudzivisa:
HPMC inovandudza iyo freeze-thaw kuramba kongiri nekuvandudza chimiro chayo chepor. Iyo yakaonda firimu HPMC mafomu akatenderedza coment zviyero zvinodzora saizi uye kubatana kwePorillary Pores, nekukasira kuderedza mukana wekusununguka-thaw kukuvara.

4. Kushandiswa kweHPMC muongongori:
4.1 kuzvimisa kongiri:
HPMC inoshandiswa zvakanyanya mukugadzirwa kwekuzvimiririra kongiri. Yayo-yekuchengetedza uye rheology-inoshandura zvinhu zvinoona kuti musanganiswa unochengetedza iyo inodiwa yekuyerera midziyo panguva yekudzivirira kusarongeka uye kujekesa kwakawanda.

4.2 Tile Adhesives uye Moturs:
Mumatehwe ehembe uye mongwe, hpmc zviito seanoti uye binder. Iyo inokwikwidza zvivakwa zvekubatanidza kwezvinhu izvi uye zvinopa kuenderana kunodiwa kune nyore kushandisa.

4.3 Kunze kweSimbiso uye Kupedza Systems (Eifs):
HPMC inoshandiswa mukudzingwa kwemadziro uye nzvimbo dzepamusoro kuti dzivandudze primer deper kusimudzira uye kusimudzira kuti ushande. Izvi zvinobatsira kuvandudza mashandiro ese uye hupenyu hurefu hwezvikumbiro zvei.

5. Kuenderana nezvimwe zvinobvumirana:
5.1 Synergy ine searnplasticastizer:
HPMC inogona kushanda synergistically nevane mashura kuti adzorere zvemvura mukodzero yemvura muConcrete musanganiswa uchiramba uchishanda. Uku kusanganisa kunowedzera simba uye kusimba kweiyo yakakonzerwa kongiri.

5.2 kuenderana nekudzosera admixture:
Kana retardeders dzinoshandiswa kunonoka nguva yekugara kongiri, HPMC inogona kukwana aya anowedzera nekuwedzera kudzikisira kushanda uye kudzokorora kwemvura kwemusanganiswa.

6. Kufungisisa kwekutsigira:
6.1 Biodengradability:
HPMC inowanzoonekwa seyakaishamwaridzana nekuti ndeye bioderables. Iyi ficha inoenderana nekuwedzera kusimbisa kwekusimbisa uye eco-hushamwari maitiro ekuvaka.

6.2 Deredza kabhoni tsoka:
Uchishandisa HPMC muConcrete Mixes inobatsira kuderedza kabhoni tsoka yemapuro ekuvaka. Nekuvandudza mashandiro uye kujaira kwekongiri, zvivakwa zvinogona kuda zvishoma kugadziriswa kana kutsiva, zvichikonzera kubatsira kwenguva refu.

7. Mhedziso:
Hydroxypruppropyl methylcellestulose inoita basa rakakosha mukusimbisa dzakasiyana siyana dzekuita kongiri. Zvekuita pakushanda, kusimba uye kuwirirana nevamwe vanomubvuma kunoita kuti ive yakakosha muindasitiri yekuvaka. Sezvo kudiwa kwezvinhu zvakakwirira-zvinoitwa uye zvakarongeka zvekuvakisa zvinowedzera kukura, HPMC inomira kunze semhinduro yemashandisirwo inobatsira kugadzirisa mashandiro ekongiri uye huwandu hwakazara hwezvivakwa.
