Hydroxypropyl Methylcellulose (HPMC)imhando ye cellulose ether isingashandisi ionic inoshandiswa zvakanyanya mukuvaka, kunyanya mukugadzira mataira. Inotorwa kubva mu cellulose yechisikigo (yakadai sedonje kana huni), uye mapoka ehydroxypropyl nemethyl anounzwa kuburikidza nekuchinja kwemakemikari, zvichiita kuti inyungudike zvakanaka mumvura, irambe ichichengetedza mvura, irambe ichinamira uye igone kuchinjika pakuvaka.
1. Basa reHPMC mukuisa mataira
Kuvandudza mashandiro ekuvaka
Kuwedzera HPMC kune glue yemataira kunogona kuvandudza mashandiro ekuvaka. Inogona kugadzirisa kugadzikana kweglue yemataira, zvichiita kuti zvive nyore kupararira zvakaenzana pamadziro kana pasi, kudzivirira kutsvedza kana kutsvedza. Zvakakosha zvikuru pakuisa mataira akamira, izvo zvinogona kuvandudza kushanda zvakanaka kwekuvaka uye kunyatsorongeka kwekuisa mataira.
Kuvandudza kuchengetwa kwemvura
Chimwe chezvinhu zvakakosha zveHPMC kuchengetedza mvura. Inogona kuvharira hunyoro nekunonoka kupinda kwehunyoro mu substrate, zvichiita kuti zvinhu zvisina kugadzirwa zve simende zvive nehunyoro hwakakwana hwekuita kuti mvura irambe ichinaya. Izvi hazvingobatsiri chete kunatsiridza kunamira kwekutanga kwetiles, asiwo zvinoderedza kudonha kwegomba nekudonha.
Kuvandudza simba rechisungo
HPMC inogadzira firimu rinochinjika mumota yesimende, izvo zvinoita kuti kubatana pakati pechinamira chemataira nemataira nechikamu chepasi chiwedzere. Hunhu hwayo hwakanaka hwekugadzira firimu uye kuchinjika kwayo kunoita kuti chikamu chinonamira chemataira chakaomeswa chive chakasimba uye chisingatsemuke, uye chinogona kugadzirisa madziro kana pasi zvichikonzerwa nekuchinja kwekushisa.
Wedzera nguva yekuvhura nenguva yekugadzirisa
Iyo inonzi "nguva yakavhurika" inoreva nguva iyo chinamira chemataira chinogona kuramba chichikwanisa kubatana zvakanaka mushure mekuparadzirwa pamusoro pevhu. HPMC inowedzera nguva ino kuburikidza nekuchengetwa kwemvura zvakanaka, ichipa vashandi vekuvaka nzvimbo yakawanda yekushanda, izvo zvinonyanya kukosha pakuvaka munzvimbo inodziya zvakanyanya kana yakaoma. Panguva imwe chete, HPMC inowedzerawo "nguva inogadziriswa" yemataira, zvichibvumira vashandi vekuvaka kugadzirisa mataira matsva kuti vave nechokwadi chekuti pavement yakanaka.
Dzivirira kutsemuka uye kupfumbuka
Mushure mekuwedzera HPMC kune tile adhesive kana simende mortar, kuchinjika kwese kwechinhu chacho kunowedzerwa, kushushikana kwekupwanyika kunoderedzwa, uye njodzi yekupwanyika kwepamusoro kunokonzerwa nekupwanyika, kuwedzera kwekupisa uye kusimba kunoderedzwa. Panguva imwe chete, kugona kwe cellulose kugadzira firimu kunoitawo kuti pamusoro pacho pasanyanya kuwa, zvichivandudza kunaka kwacho.
2. Zvinhu zveHPMC
Kunyungudika kwakasimba: HPMC inogona kuparadzirwa nekukasika uye kunyungudika mumvura inotonhora kuti iite mhinduro yakajeka isina kuungana.
Chipimo chidiki uye mhedzisiro yakakosha: Huwandu hwayo hunoshanda hwekuwedzera hunowanzova 0.3%-1.0%, izvo zvinogona kuvandudza mashandiro echinamira chemataira, nekushanda kwacho kwakachipa.
Kushanda zvakanaka nezvimwe zvinhu: HPMC inogona kushanda zvakanaka nezvimwe zvinhu zvakaita sesimende, jecha requartz, upfu hwelatex, uye mapolymers anogona kunyungudika kuti ivandudze mashandiro ekugadzira.
Inochengetedza nharaunda uye haina chepfu: HPMC chinhu chakasvibira uye chine hushamwari kune nharaunda chisina chepfu, chisina hwema, chisingakanganisi, uye chine hushamwari kune vashandi vekuvaka nenzvimbo.
3. Mazano ekushandisa uye matanho ekudzivirira
Sarudza modhi chaiyo
Nzvimbo dzakasiyana dzekuvaka nemarudzi emataira dzine zvinodiwa zvakasiyana zvekusimba kweHPMC, mwero wekutsiva, kunyungudika kwemvura nezvimwe zviratidzo. Kazhinji, HPMC ine viscosity yakakura yakakodzera nzvimbo dzekuvaka dzakamira kana mataira makuru, izvo zvinogona kudzivirira kutsvedza zviri nani; nepo mamodheru ane viscosity yakaderera akakodzera nzvimbo dzekuvaka dzine zvinodiwa zvepamusoro zvekuyera.
Mamiriro ekuchengetedza
HPMC inofanira kuchengetwa munzvimbo inotonhorera, yakaoma uye ine mhepo inofefetera, ichidzivirira kusangana nehunyoro kudzivirira hunyoro uye kuunganidzana kwemvura.
Kudzora kwakaringana kwemuyero
Kunyangwe chipimo cheHPMC chisina kukura, chine mhedzisiro yakakura pakushanda kwayo. Chipimo chakawandisa chinogona kukonzera kuoma kwenguva refu kana mimwe migumisiro, saka chipimo chinofanira kudzorwa nemazvo zvichienderana nefomura chaiyo.
Sechinhu chakakosha chinowedzera zvinhu zvekuisa matairaHPMCine basa guru mukuvandudza kuchengetedza mvura, kushanda zvakanaka kwekuvaka, kusimba kwekubatana uye kugara kwenguva refu kwematiles ekunamira. Nekusimudzirwa kwepfungwa yezvinhu zvekuvaka zvakasvibira uye kufambira mberi kuri kuitwa tekinoroji yemazuva ano yekuvaka, HPMC icharamba ichiita basa rakakosha mukuisa mataira uye indasitiri yese yezvinhu zvekuvaka. Kusarudza zvigadzirwa zveHPMC zvemhando yepamusoro uye zvinochinjika ivimbiso yakakosha yekuona kuti kuvaka kwakanaka uye kugara kwenguva refu.
