HydroxyPropyl methyl cellever (HPMC) inoshandiswa zvakanyanya mukugadzira, uye kuita kwakadzama kwekuita hpmc kunowedzera kuita uye kurova kwemotokari, kupa huwandu hwehukama uye kusarudzika kwemhando yepamusoro uye kujaira kwekuvaka zvirongwa.
Doad, chinhu chakakosha chezvinhu zvekuvaka, zvinotora basa rakakosha mukurongedza mabhuru ekuvaka uye kupa kutendeka kwechimiro kune akasiyana siyana architectural zvivakwa. Kuumbwa uye zvivakwa zvewero zvinokoshesa zvinopesvedzera kuita uye kusimba kwemasonfany anoshanda. Kuti uvandudze kugona, kuderedza, uye kuita kwevhu, kwakasiyana siyana kwakasiyana siyana kunobatanidzwa mukuumbwa kwayo. Pakati peizvi zvekuwedzera, hydroxyprupyl methyl cellelose (HPMC) inomira seyakaverengeka uye yakashandiswa zvakanyanya zvinoshandiswa. Chinyorwa ichi chinodedera muchikamu cheHPMC mune mongororo yezvinyorwa, kusimbisa mabasa ayo, mabhenefiti, uye mhedzisiro pazvinhu zvemota.
1.comemical kuumbwa uye chimiro cheHPMC:
HpMC ndeyemhuri ye cellulose etana, inotorwa kubva kune yakasikwa cellulose kuburikidza neyekutevedzana kwemakemikari kugadzirisa. Chemakero charo chemakemikari chinosanganisira kudzokorora zvikamu zve glucose mamorekuru vakadzora ne methyl uye hydroxyprupropyl mapoka. Dhigirii rekutsiva (DS) uye kutsiviwa kwemberi Kuvapo kwe hydroxyprupyl uye methyl mapoka anopa zvese hydrophilic uye hydrophobic hunhu kune hpmc, zvichiita kuti ive svutugadzike mumvura ichiratidzira zvivakwa-zvinoshanda.
2.Function yeHPMC muMoltar:
Kudzokorora kwemvura: imwe yemabasa ekutanga eHPMC muMoltar ndeyekuwedzera kuchengetwa kwemvura. Nekugadzira iyo yakaonda firimu yakatenderedza coment zvidimbu, HPMC zvinokurumidza kudzora kwemvura panguva yekuporesa kwemvura, ichiita kuti ive yakawanda hydration uye yakakwana kukura kwesimba remota. Ichi chivakwa chinonyanya kubatsira mukupisa uye yakaoma mamiriro ekunze kana panguva dzekushanda kwenguva refu.
Yakavandudzwa Workability: HPMC inoita senge rheology modifier mumotokari, ichivandudza kushanda kwayo uye kusawirirana. Kuwedzerwa kweHPMC kunowedzera kugona kwerufu kuyerera uye kuparadzira zvakanyanyisa, kufambisa nyore nyore kushandisa uye kuderedza mukana wekusaririra kana kubuda ropa. Izvi zvinonyanya kukosha mukushandisa zvakadai sekuparadza uye kushandurwa, uko kwakapfava uye vunifomu kupera kwacho kunodiwa.
Yakavandudzwa Dhizimusi: HPMC inosimudzira iri nani kushamisika pakati pevhu uye substrate nzvimbo. Kuumbwa kweiyo cohesive moter paste, yakafambiswa neHPMC, inovandudza chisungo simba uye inoderedza njodzi yekushongedza kana kushamisika. Izvi zvinonyanya kukosha mukushandisa uko motsi inoshandiswa kune dzakasiyana siyana substrates, yakadai sekongiri, zvidhinha, kana dombo.
Kupisa kuramba: Kuvhapo kweHPMC muMorm Firmations kunobatsira kuvandudza kupaza kupokana nekudzikiswa shrinkage. Nekuwedzera kubatana uye kuderedza kurasikirwa kwemvura, HPMC inobatsira kuderedza kukura kwekudzikira kwemarara, nekudaro kuwedzeredza kusimba kwakazara kwemasonfant.
3.Frants yeHPMC paMortar Zvivakwa:
Simba reMuchina: Ipo HPMC kunyanya inoshanda seyekuchengetwa kwemvura mumiririri uye kushandira enhraccer, kukanganisa kwayo kwemuchina wekusimba kwemutya. Muzhinji, kubatanidzwa kweHPMC hakuwedzere kushandura simba rekumanikidza kana rinosindimara resimba remota, rakapa kuti dosage iri mukati meiyo yakakurudzirwa. Nekudaro, kunyanyisa kushandisa HPMC kunogona kutungamira mukudzikiswa zvishoma musimba nekuda kwemidhirowa.
Kugadzika nguva: HPMC inogona kukanganisa nguva yekuisa yemota, iganda kusvika padiki. Kuvapo kweHPMC kunogona kuwedzera nguva yekutanga yekugara, kubvumira kwenguva yakareba kushanda uye nekuvandudza kupedzisa. Nekudaro, zvakanyanyisa huwandu hweHPMC kana zvisina kukodzera kusarudzwa kwegiredhi kunogona kunonoka kudzora nguva yekugara, zvinogona kukanganisa zvirongwa zvekuvaka.
Mvura inodiwa: HPMC inobatsira kuderedza iyo yemvura inodiwa yemutumbi uchiramba uchiita basa rakakwana. Ichi chivakwa chinobatsira sezvo ichibvumidza kuumbwa kweiyo mongoro yakakwirira-yekuita nemvura yakajeka yemvura ine huwandu hwemvura, zvichikonzera simba rakatsvukwa, kusimba, uye kuramba zvinhu zvakatipoteredza.
4.Practical Zvikumbiro zveHPMC muMoltar:
Kuvakwa maseal Kugona kwayo kuvandudza basa rekushanda, kudenha, uye kuchengetwa kwemvura kunoita kuti ive yakakosha yekuwana kuwana yakakwirira-mhando motsi inosanganiswa yakakodzera pakuvaka akasiyana siyana ekuvaka.
Plaservering uye kushandurwa: Mukuparadzira uye kuisirwa zvikumbiro, HPMC inobatanidzwa muumbi mafambiro ekusimudzira kushanda uye kuwana zvakapfava, yunifomu inopedza. Iko kushandiswa kweHPMC kunobatsira kudzivirira sagging kana kupaza panguva yekushandisa, zvichikonzera kuaineshetically inofadza uye inogara nzvimbo.
Tile anomhara uye Grouts: HPMC inoita basa rakakosha muTile inonamatira uye mafambiro ekurongedza, uko kunovandudza kudiwa, kuchengetwa kwemvura, uye kusawirirana kwemvura. Nekuona kunyorova kwakanyorova uye kusungwa pakati pematiles uye substrates, hpmc inobatsira kugadzira yakasimba uye yakareba-inogara-nguva yekuvandudza kumvura inomira uye mashandiro emvura.
Kugadziriswa uye Kudzoreredza: Mukugadziriswa uye Kudzoreredza Mapurojekiti, HPMC-Modified Mouts Modars anowanzo kuwanikwa kugadzirisa midziyo yakakuvara, uye dzorera marara, uye dzorera zvigadzirwa zvezvivakwa. Kubatanidzwa kweHPMC kunowedzera kubatana uye kuderedza kwekugadzira mota, kuona kusanzwisisika kusanzwisisika neapo kusevha uye kusarudzika kwenguva refu.
HydroxyPropyl methyl Cellel Cellelose (HPMC) inoita basa rakakosha mukuwedzera mashandiro, kushanda, uye kusimba kwemutya mune zvekuvaka zvekushandisa. Yayo yakasarudzika yekuchengetwa kwemvura, rheology kushandurwa, uye inonamira kukwidziridzwa zvivakwa kunoita kuti ive iyo inopindirana nayo yekugadzira motsi-yemhando yemhando yepamusoro. Nokunzwisisa mabasa uye miganho yeHPMC, nyanzvi dzekuvaka dzinogona kurongedza maumbirwo marefu kuti usangane nezvakangoita basa raida, kuona kubudirira uye kuzere kwesononny inoshanda.
