Iyo huwandu hwe hydroxypropyl methylcellose (HPMC) muPutty poda ndeimwe yezvakakosha zvinhu zvinoona kuita kwePutty poda. Kunzwisisa HPMC Kuwedzeredza kunogona kuvandudza basa rekushanda, kudzokorora kwemvura, kujaira kwePutty poda, nepo kuwedzeredza kana kusakwana kwekuwedzera kuchakanganisa mhedzisiro yekupedzisira yePutty poda.
1. Basa reHPMC mune putty poda
HPMC chinhu chinowanzoshandiswa-mvura-soluble polymer ine inotevera mabasa makuru:
(1) Kuwedzeredza Kuchengeta mvura
Basa guru reHPMC rekuchengetwa kwemvura yekuchengetwa kwePutty poda
(2) kuvandudza basa rekushanda
HPMC inogona kuvandudza lubricity yePutty poda, ita kuti kupuruzira svutugadzike, kuderedza kudzikisira, kugadzirisa kugona kuvaka kuvaka, uye kuderedza kusimba kwevashandi vekuvaka.
(3) Kuvandudza kuderedza
HPMC inogona kusimudzira iyo yekushambadzira pakati pePutty poda neWall base, dzivirira iyo putty layer kubva pakudonha, uye kugadzirisa kusimba.
(4) kudzivirira kutsvedza
Munguva yekuvaka, HPMC inogona kudzivirira zvinobudirira poda poda kubva pakutsvedza nekuda kwekusuruvara, kugadzirisa mhando yekuvaka, kunyanya kana matema kana akavakwa matema.
2. Zvinhu zvinokanganisa HPMC
Iyo huwandu hweHPMC inokanganiswa nezvinhu zvakawanda, kusanganisira iyo formula yePutty poda, nzvimbo yekuvaka, uye mhando yeHPMC.
(1) formula ye putty poda
Putty poda inowanzoumbwa neyekuremerwa calcium (calcium kabhoni), kaviri kubhururuka ash, simende, lime poda, etc. yakasiyana mafomula ine zvisizvo zvido zveHPMC. Semuenzaniso, putty-yakavakirwa-putty inoda mvura yakawanda yeiyo hydration maitiro, saka huwandu hweHPMC yakashandiswa ichave yakakwirira.
(2) Nzvimbo yekuvaka
Tembiricha, humidity, uye mvura yekunyora yemugodhi yeiyo base layer inokanganisawo huwandu hweHPMC yakashandiswa. Mune tembiricha yakadzika uye yakaoma nzvimbo, kuitira kudzivirira kunyanyisa kwemvura, zvinowanzo kuve zvakakosha kuti uwedzere huwandu hweHPMC.
(3) HPMC mhando
HPMC yemhando dzakasiyana siyana uye mhando dzine zvivakwa zvakasiyana senge viscosity, kutsiva degree, uye kujekeswa, uye zvine mhedzisiro dzakasiyana paPutty poda. Yakakwira-viscosity HPMC ine zviri nani kudzokorora kwemvura, asi zvinogona kukanganisa basa, saka zvakakodzera kusarudza yakakodzera mhando zvinoenderana nemamiriro ezvinhu chaiwo.
3. Yakakurudzirwa Dosage yeHPMC
Iyo Yakakurudzirwa Dosage yeHPMC kazhinji inosiyana zvichienderana nerudzi rwePutty poda:
(1) Yemukati madziro putty poda
Iyo Yakakurudzirwa Dosage yeHPMC inowanzo kuve 0.2% ~ 0.5% (hama (inoenderana nehuwandu hwehuwandu hwePutty poda). Kana iyo viscosity yeHPMC yakakwira, iyo yakakurudzirwa dosage iri pedyo neiyo yakaderera kukosha; Kana iyo viscosity yakaderera, inogona kuwedzerwa nenzira kwayo.
(2) Kunze kweWall Wall Putty poda
Exterior Wall Kuparadzanisa Kunoda Kuramba Kwemamiriro ekunze uye kupaza HPMC yakawedzerwa kazhinji ndeyekuwedzera pakati pe 0.3% ~ 0.6% yekushomeka kuchengetwa kwemvura uye kudedera.
(3) gobvu danda putty
Kune gobvu layer putty, kuitira kudzivirira kukurumidza kurasikirwa kwemvura uye kupaza, huwandu hweHPMC yakawedzerwa inogona kuwedzerwa nenzira kwayo, kazhinji pakati pe 0.4% uye 0.7%.
4. Kuchera
(1) Dzivisa kuwedzera kwakawandisa
Kuwedzera zvakawandisa HPMC kunogona kukonzera vhiza yeiyo putty kuti ive yakanyanya kuwanda, kuita kuti kuvakwa kwakaoma, kupenya kusiri kupenya, uye kutokanganisa kushungurudzika kana kupaza kana kupaza.
(2) Sarudza iyo chaiyo modhi
HPMC ine zvisizvo viscooki yakakodzera mhando dzakasiyana dzemhando dzePutty poda. Semuenzaniso, HPMC neyakaderera viscosity (400-20000MPA · Zvakafanana Mukati) Ipo HPMC neViskmsity (75,000-100,000MPASMS (75,000-100,4-100,4MSM
(3) Kupararira zvine musoro uye kupaza
HPMC inofanira kuve yakanyatso kuparadzirwa panguva yekugadzira yekugadzira kuti udzivise kuunganidzirwa yakakonzerwa nekuwedzera kwakananga mumvura. Inokurudzirwa kuwedzera zvishoma nezvishoma pasi peyakaderera-kumhanya kumhanyisa, kana kushandisa nzira yekutanga kusanganisa nedzimwe podes uye wozowedzera mvura kuti isimbise.
(4) Shandisa nezvimwe zvinowedzera
HPMC inowanzoshandiswa pamwe chete nedzimwe zvinowedzera (senge starch ether, redispersle latex poda, etc.) kuti uwedzere kuitwa kwePutty poda.
Iyo huwandu hweHPMC mune putty poda chinhu chakakosha chinokanganisa basa rekushanda uye mhando yechigadzirwa chakapera. Kazhinji. Paunenge uchisarudza HPMC, iyo viscosity, degree rekutsiva uye humwe hunhu hunofanirwa kunge hwakasanganiswa kuti uve pachena hupfu hwekuchengetwa kwemvura, kudenha uye kuita kwekuvaka. Panguva imwecheteyo, kusanganiswa zvine musoro kune mamwe maitiro ekuwedzera uye kushandisa nzira chaiyo inogona kushandisa basa reHPMC, nekukasira kuvandudza mhando yemhando yepamusoro yePutty poda.
