Hydroxypropyl Methyl Cellulose (HPMC, Hydroxypropyl Methyl Cellulose) i polymer material inoshandiswa zvakanyanya mu putty powder. Iyo ine yakanaka solubility yemvura, kunamatira, kuchengetedza mvura, kukora, kugadzira firimu uye lubricity, saka inoita basa rakakosha muputty poda.
1. Kuchengeta mvura
Rimwe remabasa akanyanya kukosha eHPMC mune putty poda ndeyekupa yakanakisa kuchengetedza kwemvura. Putty poda inoomesa mushure mekushandisa, nepo HPMC ichichengeta hunyoro uye inorebesa nguva yekuomesa. Ichi chimiro chinobvumira iyo putty poda kuti ive nenguva yakareba yekushanda panguva yekurapa, iyo inobatsira pakuvaka. Kuchengetedza mvura kunodzivirirawo kuputika kweputty layer, kuvandudza simba uye kugadzikana kwechigadzirwa chakapedzwa.
2. Kukora
Seyakakora mumiriri, HPMC inogona kuwedzera zvakanyanya viscosity yeputty poda, ichiita iyo putty poda yakawanda uye kunyangwe ikaiswa. Inogona kugadzirisa kuwirirana kweputty poda kudzivirira kudonha kwezvinhu uye matambudziko ekuvaka, nekudaro kuve nechokwadi chekuti putty poda inogona kupfekedzwa zvakaenzana pamadziro pasina kuyerera, kuvandudza kunaka kwekuvaka.
3. Mafirimu ekugadzira zvinhu
Iyo firimu yakaumbwa neHPMC panguva yekuomesa inogona kuwedzera simba repamusoro uye kusimba kweputty powder. Mafirimu ekugadzira zvivakwa chinhu chakakosha mukugona kweputty kuramba kutsemuka uye kupfeka. Iyi firimu chimiro hachingodziviriri kutsemuka kwepasi pe putty layer, asi zvakare inosimudzira kuramba kweiyo putty layer kune zvakatipoteredza, senge UV kuramba uye hunyoro kuramba.
4. Lubricity
HPMC ine lubricity yakanaka uye inobatsira kuvandudza kuita kwekuvaka kweputty poda. Munguva yekusanganisa uye yekuvaka maitiro eputty poda, iyo lubrication mhedzisiro yeHPMC inoita kuti zvive nyore kubvongodza putty poda zvakaenzana uye kuishandisa zvakanaka pamadziro. Izvi hazvingoite kuti kuvaka kuve nyore, asiwo kunoderedza kusakara uye kubvaruka kwezvishandiso zvekuvaka.
5. Kugadzikana
HPMC inogona kuvandudza zvakanyanya kugadzikana kweputty powder. Inogona kudzivirira putty poda kubva pakugadzirisa, agglomerating uye mamwe matambudziko panguva yekuchengetedza uye kuve nechokwadi kugadzikana kwenguva refu kwechigadzirwa. Uku kudzikamisa mhedzisiro yeHPMC inodzivirira iyo putty poda kubva pakumutswa kakawanda isati yashandiswa uye inochengetedza yunifomu yemhando.
6. Kuvandudza anti-slip performance
Paunenge uchigadzira madziro akatwasuka, kana iyo putty poda isina yakanaka anti-slip zvimiro, inowanzoita sagging uye sagging. Iko kunamatira uye kukora mhedzisiro yeHPMC inovandudza zvakanyanya anti-slip performance ye putty poda, kuve nechokwadi chekuti zvinhu zvacho zvinogona kusungirirwa zvakasimba kumadziro kuita nzvimbo yakati sandara, yakatsetseka.
7. Kuwedzera kuvakwa
Kuvepo kweHPMC kunoita kuti putty poda ive nyore kuvaka, inoderedza kunamatira kwezvishandiso, uye inovandudza kushanda kwekuvaka. Inogona kuita kuti putty powder isanyanya kuomerera kune zvishandiso panguva yekuvaka, kuderedza kupikisa panguva yekushandiswa, nekuvandudza kunyaradza uye mhedzisiro yekuvaka.
8. Rongedza maawa ekuvhura
HPMC inogona kugadzirisa nguva yekuvhura yeputty powder. Nguva yekuvhura inoreva nguva iyo putty powder inogona kugadziriswa uye kuchekwa mushure mekuvaka. Nekudzora huwandu hweHPMC hwakawedzerwa, nguva yekuvhura yeputty poda inogona kukwidziridzwa zvakakodzera kana kupfupikiswa kuti ienderane kune zvakasiyana zvinodiwa zvekuvaka.
9. Vandudza crack resistance
Nekuda kwekukora uye kuchengetedza mvura zvivakwa zveHPMC, inogona kunyatso kudzivirira iyo putty poda kubva pakuderera uye kuputika nekuda kwekurasikirwa kwemvura yakawandisa panguva yekuomesa. Inogona kupa elasticity yakakodzera, ichibvumira iyo yakaomeswa putty layer kuti irambe kushushikana kwekunze uye kuderedza kuitika kwekutsemuka kwepasi.
10. Kuvandudza kusamira kwemamiriro ekunze
HPMC inogona kuwedzera kumira kwemamiriro ekunze kweputty poda uye kudzivirira kuchembera uye kuparara kweiyo putty layer munzvimbo dzakaoma. Nekuda kweiyo firimu-inogadzira zvivakwa uye kugadzikana kweHPMC, inogona zvinobudirira kurwisa ultraviolet erosion uye humidity shanduko, kuwedzera hupenyu hwebasa reputty poda.
HPMC inotamba akawanda mabasa mu putty poda. Kubva pakuchengetedza mvura, kukora, uye kuumbwa kwemafirimu kusvika pakusimudzira mashandiro ekuvaka uye kuvandudza kuramba kwekuputika, inoita basa rakakosha mukuita uye kuvaka mhedzisiro yeputty poda. Kushandiswa kwaro kunoita kuti putty powder ive nekuita zviri nani kuvaka, kugadzikana uye kusimba, kupa vimbiso yakakosha yekuvaka madziro. Muchidimbu, HPMC chinhu chakakosha uye chakakosha cheputty powder uye inoita basa risingadzoreki mukuvandudza kushanda kwese kweputty powder.
