HPMC (Hydroxypropyl Methylcellulose) chiwedzerwa chinoshandiswa zvakanyanya mukuvaka, kunyanya mukuvaka senge gypsum plaster. HPMC is a non-ionic cellulose ether inogadzirwa nekuita natural cotton cellulose ine sodium hydroxide uyezve etherifying iyo nemethyl chloride uye propylene oxide. Nekuda kwehunhu hwayo hwakanaka, HPMC inoshandiswa zvakanyanya muindasitiri yekuvaka kunyanya mune gypsum-based materials.
Zvivakwa uye maitiro eHPMC
Kuomesa mhedzisiro: HPMC inogona kuwedzera zvakanyanya viscosity yegypsum plaster, zvichiita kuti musanganiswa uve nyore kubata panguva yekuvaka. The thickening effect haingobatsiri kuwedzera kushanda kwemusanganiswa asiwo inovandudza kunamatira kwayo kune substrate.
Kuchengetedzwa kwemvura: Mu gypsum plaster, HPMC inoshanda sechinhu chekuchengetedza mvura, ichichengeta mvura iri musanganiswa kuti isanyungudika zviri nyore. Ichi chivakwa chinoita basa rakakosha mukuita kwekuvaka kwegypsum plaster, kunyanya munzvimbo dzakaoma, kudzivirira kuoma nguva isati yakwana kana kuputika nekuda kwekurasikirwa nekukurumidza kwehunyoro.
Kuvandudza mashandiro ekuvaka: Iyo lubricity yeHPMC inogona kuvandudza kuyerera uye kuparadzira kuita kwechinhu, nekudaro ichidzikisa kuramba panguva yekuvaka uye kuita kuti zvive nyore kuti plaster ipararire zvakaenzana.
Kunonoka kuseta nguva: HPMC inogona zvakare kunonoka yekutanga kuseta nguva yegypsum plaster, ichipa vashandi vekuvaka nguva yakareba yekushanda kuti vagadzirise uye kugadzirisa. Iyi ficha inonyanya kukosha mukuvaka-nzvimbo yakakura kana yakaoma-yakaita madziro marapirwo.
Basa reHPMC mune gypsum plaster
Yakanatsiridzwa yekunamatira: HPMC inogonesa gypsum plaster kuti inamire zvakasimba kune substrate pamusoro panguva yekushandiswa, ingave madziro, sirin'i kana imwe nzvimbo yekuvaka, inopa yakanaka yekubatanidza zvivakwa uye kudzivirira iyo plaster kubva kusvuuka kana kutsemuka.
Enhanced crack resistance: Nekuti HPMC ine yakanakisa yekuchengetedza mvura zvivakwa, inogona kuderedza yakawandisa evaporation yemvura, nekudaro kudzivirira shrinkage isina kuenzana yegypsum plaster panguva yekuomesa, kuderedza kuitika kwekutsemuka, uye kuwedzera kusimba kwechigadzirwa chekupedzisira.
Yakavandudzwa sag kuramba: Mune zvimwe zvivakwa zvakamira, kunyanya kupurasita madziro, kuvapo kweHPMC kunogona kudzivirira plaster kubva pakutsvedza pasi nekuda kwesimba rinokwevera zvinhu pasi, ichisimbisa kugadzikana kwemusanganiswa kuitira kuti igone kunamatira zvirinani kune dzakamira kana dzakatsvuka nzvimbo. pamusoro.
Kunatsiridza kupfeka uye kuramba kwechando: HPMC inopa gypsum plaster kukura kwakanyanya kuabrasion yemuviri uye nechando-kunyunguduka kuramba munzvimbo dzakaderera-tembiricha. Izvi zvinonyanya kukosha pakuvaka kwekunze kana kushandiswa munzvimbo dzine hunyoro.
Kushandiswa uye kushamwaridzana kwezvakatipoteredza kweHPMC
HPMC pachayo inogadziriswa kubva kune yakasikwa zvinhu donje cellulose uye ine yakanaka biodegradability uye kushamwaridzana kwezvakatipoteredza. Sechinhu chisina chepfu uye chisingakuvadze, HPMC haizokonzerese kukuvadza kune vashandi vekuvaka uye nharaunda. Naizvozvo, HPMC zvakare isarudzo inoremekedzwa zvakanyanya mukugadzira uye kushandiswa kwezvinhu zvakasvibirira zvekuvaka.
Chengetedzo kana uchishandisa HPMC
Kuenzanirana kunonzwisisika: Mugadziriro yegadziriro yegypsum plaster, huwandu hweHPMC hwakawedzerwa hunoda kuenzaniswa zvinoenderana nezvinodiwa zvekuvaka uye hunhu hwezvinhu. Yakawandisa kana yakawandisa HPMC inogona kukanganisa mashandiro emusanganiswa, semuenzaniso yakawandisa viscosity inogona kutungamirira kunetsa mukubata, nepo kusakwana viscosity kunogona kukonzera kusabatana zvakanaka.
Inochinjika kune dzakasiyana nharaunda: Kuchengeta mvura kweHPMC uye kunonoka kuseta nguva zvivakwa zvinoita kuti ive yakakodzera kune akasiyana mamiriro ekunze, asi munzvimbo dzine hunyoro hwepamusoro kana tembiricha yakaderera, fomula yekushandisa ingangoda kugadziridzwa kuti ive nechokwadi chekuvakwa kwakanaka.
Kuchengeta uye Kubata: HPMC inofanirwa kuchengetwa munzvimbo yakaoma, ine mhepo inofefetera kure nekunyorova uye tembiricha yepamusoro kuti ive nechokwadi chekuti zvinhu zvayo zvinoshanda hazvikanganiswe. Panguva yekushandiswa, kutarisirwa kunofanira kutorwa kudzivirira kunyura kwakanyanyisa kunyorova kudzivirira kukanganisa kushanda kwayo.
Musika uye tarisiro yekusimudzira yeHPMC
Sezvo kudiwa kweindasitiri yekuvaka kwepamusoro-kuita, akawanda-anoshanda zvekuvaka anowedzera, tarisiro yekushandiswa kweHPMC mune gypsum plaster inovimbisa zvikuru. Haisi kungovandudza kushanda kwese kwezvivakwa zvekuvaka, asi zvakare inopindirana neyezvino girinhi uye zvakatipoteredza zvine hushamwari mazano ekuvaka. Panguva imwecheteyo, nekufambira mberi kwetekinoroji, maitiro ekugadzira eHPMC anozovandudzwa uye mutengo unotarisirwa kudzikiswa, ichikurudzira kushandiswa kwayo kwakakura muindasitiri yekuvaka.
Sekuwedzera kwakakosha mune gypsum plaster, HPMC ine zvakawanda zvakanakisa zvivakwa zvakaita sekukora, kuchengetedza mvura, uye yakawedzerwa nguva yekushanda. Inogona kuvandudza zvakanyanya kuita kwekuvaka uye kusimba kweiyo gypsum-yakavakirwa zvinhu. Hushamwari hwayo kwezvakatipoteredza uye husina chepfu hunhu zvakare hunoita kuti ive imwe yeakakosha zvigadzirwa muindasitiri yekuvaka yemazuva ano. Mune ramangwana rekuvandudza kwezvinhu zvekuvaka, HPMC inotarisirwa kuita basa rakakosha uye nekusimudzira kufambira mberi kwetekinoroji uye kuvandudzwa kwekuita kwezvinhu zvekuvaka.
