Hydroxypropyl Methylcellulose (HPMC)chinhu chakakosha chekuvaka chinowedzera uye chinoshandiswa zvakanyanya mu putty, mataira anonamira, madziro ekuvhara, uye mamwe minda. Kuita kwayo kwepamusoro kwakavandudza zvakanyanya putty kuvaka glue. Ichi chinyorwa chichaongorora kurongeka kweputty kuvaka glue zvichibva pane basa reHPMC cellulose uye kuongorora kudiwa kwayo kwemusika uye maitiro ekusimudzira.
(1) Tsanangudzo yeglue yekuvaka
Putty building glue inamira yechivako inoshandiswakugadzirisa nekuzadza nzvimbo dzekuvakazvakadai semadziro, sirin’i, uye pasi. Basa rayo guru nderekusimudzira kunamatira, fluidity, uye kuvaka kwekuita kwe putty. Kuti uvandudze maitiro ekuvaka uye ekupedzisira kuomarara mhando yeputty, akawanda putty kuvaka glues anowedzera zvimwe zvakagadziridzwa zvinhu, seHydroxypropyl Methylcellulose (HPMC).
HPMC inotamba anotevera mabasa makuru mu putty:
- Kuvandudza fluidity:HPMC inogona kunyatso kuvandudza fluidity ye putty slurry, zvichiita kuti kuvaka kuve nyore uye nyore kushanda.
- Kuwedzera adhesion:HPMC inogona kuwedzera simba rekubatanidza pakati peputty uye madziro kana base layer, kuderedza kudurura uye kupaza.
- Wedzera nguva yekuvhura:Mushure mekuwedzera HPMC, iyo nguva yekushanda ye putty inogona kuwedzerwa, iyo inobatsira kugadzirisa mamiriro ekuvaka uye kuderedza marara.
- Kudzivirira stratification uye kunaya:HPMC zvakare ine kumwe kuchengetwa kwemvura, iyo inodzivirira stratification uye kunaya kwemvura panguva yekuchengetedza uye kushandiswa.

(2) Chikamu chekuvaka glue ye putty
Kurongeka kweglue yekuvaka ye putty inogona kukamurwa zvichienderana nekuumbwa kwayo, basa, mamiriro ekushandisa, uye zvimwe zvinhu. Kazhinji kutaura, putty glue inogona kukamurwa muzvikamu zvinotevera:
1. Kurongeka nekuumbwa
Mvura-based glue
Mvura-based glue ndiyo inowanzozivikanwa yeputty glue. Nheyo yayo yepasi ndeyemvura-inonyungudika resin uye mamwe-anonyungudika emakemikari ekuwedzera. Mvura-based glue ine zvakanakirakuchengetedzwa kwezvakatipoteredza, kwete-chepfu, uye hapana hwema. Inosangana nezvinodiwa zvezvivakwa zvakasvibirira uye inokodzera kushongedza kwemba, zvivakwa zveveruzhinji, nedzimwe nzvimbo. HPMC, sechinhu chakakosha chemvura-based glue, inogona kunyatso kuvandudza simba rayo rekubatanidza uye kuita kwekuvaka.
Solvent-based glue
Solvent-based glue inoshandisa solvent senzira yekuparadzira. Ine ahigh bonding simbauye kazhinji yakakodzera kune dzimwe nzvimbo dzekuvaka dzakakosha, senge nzvimbo dzine hunyoro hwepamusoro. Kunyange zvazvo glue inonyungudutsa ichishandiswa zvakanyanya, kushandiswa kwayo muzvivakwa zvemazuva ano kunoganhurirwa nekuti zvinonyungudutsa zvinonyungudutsa zvinogona kusvibisa nharaunda.
2. Kurongeka nebasa
Ordinary putty glue
Ordinary putty glue inokodzera kugadziriswa kwemadziro mudzimba dzakawanda uye zvivakwa zvekutengesa. Basa rayo guru nderekuwedzera adhesion pakati pe putty uye base layer uye kugadzirisa mashandiro ekuvaka. Mutengo weglue uyu unowanzo kuve wakaderera uye wakakodzera kune yakakura-chiyero maapplication.
Waterproof putty glue
Waterproof putty glue yakagadzirirwa kurarama nenzvimbo dzine hunyoro kana mapurojekiti ekuvaka anosangana zvakananga nemvura, senge yekugezera, kicheni, nedzimwe nzvimbo. Iyo haina chete kuita kweyakajairwa putty glue, asi zvakare zvinobudirira kudzivirira hunyoro kubva mukati memadziro. Waterproof putty glue inowanzo wedzera mamwe akakosha ekuwedzera mvura, senge emulsion isina mvura uye simende-based zvinhu.
Anti-crack putty glue
Anti-crack putty glue inonangana nedambudziko rekutsemuka rinogona kuitika pamadziro panguva yekushandiswa, uye inovandudza kutsemuka kwayo kuburikidza neakagadziridzwa resin kana elastic enhancers. Iri rudzi rweputty glue rinowanzo shandiswa muzvivakwa zviri nyore kukanganiswa nekushanduka kwekushisa kana kudengenyeka kwechimiro, senge madziro ekunze, matenga, uye zvimwe zvikamu.

3. Kuronga nenzira yekuvaka
Manual kuvaka glue
Iyi glue inokodzera nzira dzechinyakare dzekugadzira manyorerwo, uye inoda kupedzwa nebhurasho remanyorero, kuzora, nezvimwe. Chinhu chayo chikuru ndechemutengo wakaderera uye wakakodzera kugadzirisa diki-diki kana kushongedza.
Mechanical spray glue
Mechanical spray glue inonyanya kushandiswa mumapurojekiti makuru ekuvaka, kunyanya zvivakwa zvepamusoro zvinoda kuwanda kweputty coating. Kushandisa michina yekupfapfaidza yekuvaka haingogone kuvandudza kugona kwekuvaka, asi zvakare kuve nechokwadi chekugovera yunifomu yeglue uye kuderedza marara.
4. Kurongwa nezvinowedzerwa
Ordinary putty glue
Iri rudzi rweglue rinoshandisa zvakajairwa additives uye rakakodzera kune general madziro kuvaka. HPMC inoita basa rinokosha mairi, kuvandudza fluidity uye operability.
Yakagadziriswa putty glue
Modified putty glue inowedzera mamwe makemikari anowedzera, akadai sepolymer emulsions, elastomers, nezvimwe. Izvi zvinowedzera zvinogona kuvandudzakunamatira, elasticity uye kusagadzikana kwemamiriro ekunzeyeglue, uye inonyanya kukodzera kumabasa ekuvaka anodiwa zvikuru.

(3) Kudiwa kwemusika uye maitiro ekusimudzira
Nekukurumidza kukura kweindasitiri yekuvaka, kudiwa kweglue yekuvaka yeputty kuri kuwedzera. Kunyanya muchirevo chekuwedzera kuomesera kwekuchengetedza kwezvakatipoteredza zvinodiwa,mvura-based putty glue zvishoma nezvishoma yave iyo huru yemusika. Kuitira kuzadzisa kudiwa kwemusika, vazhinji vagadziri veHPMC cellulose vari kuwedzera kuedza kwavo kweR&D kusimudzira kuvandudzwa kwetekinoroji yekuvaka glue yeputty. Somuenzaniso, vagadziri vakawanda vari kutanga kukuralow-VOC (volatile organic compounds) kana VOC-isina zvakatipoteredza zvine hushamwari glueskusangana nezvinodiwa zvezvivakwa zvakasvibirira.
Nekufambira mberi kwehunyanzvi hwekuvaka, tekinoroji yekupfapfaidza tekinoroji iri kuitawo maitiro. Iyi nzira haingogadziri kushanda kwekuvaka, asiwo inoderedza kudiwa kwevashandi, saka inoshandiswa zvakanyanya muzvivako zvepamusoro-soro, zvivakwa zvekutengeserana, uye mamwe minda.
Kurongeka kweglue yekuvaka ye putty inonyanya kukamurwa zvichienderana nemhando dzakasiyana senge kuumbwa, basa, uye nzira yekuvaka. Sekuwedzera kwakakosha,HPMCinoita basa rakakosha mukuvandudza mashandiro, kuita kwekuvaka, uye kunamatira kweputty glue. Nekuwedzera kuri kuda kwezvivakwa zvekuvaka zvine hushamwari uye zvine hushamwari mumusika wekuvaka, glue yekuvaka yeputty icharamba ichikwidziridza uye kukura mune yakasvibira, ine hushamwari, uye inoshanda gwara. Vagadziri veHPMC cellulose vanoita basa rakakosha mukuita uku, uye hunyanzvi hwavo hwechigadzirwa uye kuvandudzwa kwetekinoroji zvinokanganisa zvakananga gwara remusika wese.
