Hydroxypropyl methylcellulose (HPMC)chinhu chinoshandiswa zvakanyanya mukugadzira zvinhu zve polymer mumasisitimu e mertar, chinowanzoshandiswa kuvandudza kuchengetedza mvura mumertar, kushanda zvakanaka, uye kushanda zvakanaka. Chinowedzera zvakanyanya kunamira kwemortar, chinowedzera kushanda zvakanaka, uye chinovandudza kupararira uye hunhu husingatsvedzeri. Nokudaro, chinoshandiswa zvakanyanya mumafomura ekushandisa akasiyana-siyana, kusanganisira ma tile adhesives, plaster mortars, self-leveling mortars, uye thermal insulation systems. Zvisinei, sezvineiwo nezvimwe zvinhu, kushandiswa kwacho kune zvakwakanakira, uye kushandiswa kweHPMC mumortar kunewo zvimwe zvinhu zvakaipa kana zvipingamupinyi zvinoda kufungwa nezvazvo.
1. Zvinokonzera Mutengo
HPMC imhando ye cellulose ether yakagadziriswa, uye zvinhu zvayo zvekugadzira uye maitiro ekugadzira zvakaoma. Kana tichienzanisa nezvinhu zvemazuva ano zvisingasanganisike kana zvimwe zvinowedzera zve organic zvine huremu hushoma, mutengo wayo wakakwira zvakanyanya. Kune mapurojekiti anoshandisa huwandu hwakawanda hwemortar, kuwedzera HPMC yakawandisa kunogona kuwedzera zvakanyanya mutengo wekugadzira. Izvi zvinogona kuva muganho mumapurojekiti ekuvaka anodhura zvakanyanya.
2. Kuwedzera Kuvimba Nekuvaka
HPMC inovandudza mashandiro ekuvaka mudura kunyanya nekuwedzera kusimba kwemvura uye kuwedzera kuchengetwa kwemvura. Kana vashandi vekuvaka vakanyanya kuvimba nekusanganiswa uku uye vakaregeredza kudzora chiyero chemvura nesimende, kuyera huwandu hwesero, uye mamwe magadzirirwo ekutanga ekugadzira, izvi zvinogona kutungamira mukugadziriswa kwehunhu hwedura kune divi rimwe chete. Semuenzaniso, nepo kunamira uye kuchengetedza mvura kuchigona kuwedzerwa, simba kana kuderera kunogona kusave kwakakodzera, zvichikonzera kutsemuka kwenguva refu.
3. Kukanganisa Kushanda Kwekuomesa
HPMC inosimbisa kuvandudza kushanda zvakanaka uye hunhu hwe rheological hwe mortar itsva. Zvisinei, panguva yekuoma, cellulose ethers haibatanidzwi mukuita kwe hydration ye cement. Kuwanda kwe dose kunogona kunonotsa hydration ye cement, zvichideredza kukura kwesimba re mortar pakutanga, kunyanya mumamiriro echando uye hunyoro. Kunonoka uku, kunyange zvazvo kuchibatsira mune mamwe mashandisirwo anoda nguva refu yekushanda, kunogona kuva zvikanganiso mumapurojekiti ari kutsvaga kuwedzera simba nekukurumidza.
4. Njodzi yekudzikira uye kutsemuka
HPMC inogona kuwedzera zvakanyanya kuchengetwa kwemvura mudhaka uye kuderedza kupwanyika nekukurumidza. Zvisinei, kuchengetwa kwemvura zvakanyanya kunogona kuwedzera kupwanyika kwekutanga kwedaka resimende panguva yekuoma, zvichigona kuwedzera njodzi yekupwanyika kwedaka munzvimbo dzakati. Uyezve, kuchengetwa kwemvura yakawanda zvinorevawo kuti hunyoro hunoramba huri mudhaka kwenguva yakareba. Kana mushure mekuoma kusina kukwana, kuoma kusina kuenzana kunogonawo kukonzera kupwanyika kwepamusoro.
5. Kuenderana Nezvimwe Zvimwe Zvinosanganiswa
Pamusoro peHPMC, maformula emazuva ano emortar anowanzo sanganisira upfu hwepolymer hunonyungudika (RDP), starch ethers, zvinoderedza mvura, uye zvinopinza mhepo. Kugadzirwa kweformula kusingakodzeri kunogona kukonzera kudyidzana kunopesana pakati peHPMC nezvimwe zvinosanganiswa. Semuenzaniso, kudyidzana pakati pezvimwe zvinoderedza mvura nemacheni epolymer kunogona kukanganiswa nekunaka kweHPMC, zvichideredza kuyerera kwemvura. Neimwe nzira, kusanganiswa kweHPMC nemastarch ethers kunogona kukonzera mortar yakanyanyisa kusviba, zvichikanganisa kushanda. Naizvozvo, kuyedzwa kwekuenderana uye kugadzirisa kwakakosha mukushandiswa kwemabasa.
6. Mamiriro Ezvakatipoteredza
Hunhu hwekukora uye hwekuchengetedza mvura hweHPMC hunosiyana zvichienderana nekupisa uye simba reionic remushonga. Munzvimbo dzine tembiricha yakakwira, viscosity yemhinduro dzeHPMC inowanzo kudzikira, zvichiita kuti dzisanyanya kusimba kuchengetedza mvura. Uyezve, hunhu hwadzo hwekukora hunogona kukanganiswa mumvura yakaoma kana masisitimu ane munyu wakawanda. Izvi zvinoreva kuti kushanda kweHPMC kunogona kusagadzikana mumamiriro ekunze akasiyana kana mamiriro ekuvaka, zvichiita kuti pasarudzwe giredhi rakakodzera zvichienderana nemamiriro emunzvimbo.
7. Kuoma Kwekudzora Chipimo Chemushonga
Chiyero chinoshanda cheHPMC chakamanikana. Kana chiyero chakanyanya kuderera, zvichave zvakaoma kuwana mhedzisiro inodiwa yekuchengetedza mvura uye kukora. Kana chiyero chakanyanya kukwira, dhaka rinenge rakanyanya kusimba, rakaoma kupfava panguva yekushandiswa, kana kuti risingafambi zvakanaka, kana kutoita "stringy", zvichikanganisa kutsvedzerera kwepamusoro. Uyezve, kusviba kwakanyanya kunogona kuita kuti zviome kubvisa mabubble emhepo, zvichideredza huwandu hwedhaka uye, zvichikanganisa simba rayo nekugara kwenguva refu.
Paunenge uchiwedzeraHPMCKuisa muhari kunogona kuvandudza zvakanyanya kuchengetedza mvura, kushanda zvakanaka, uye kunamira, zvakare kune zvakunokuvadza zvakaita sekuwedzera kwemutengo, kuomesa zvishoma nezvishoma, kuwedzera njodzi yekudonha, kusawirirana kushoma nezvimwe zvinhu, uye kudzora muyero wemuyero. Mukushandiswa kweinjiniya, mhando yeHPMC nemuyero zvinofanirwa kusarudzwa zvakakodzera zvichienderana nerudzi rwemuhari, nzvimbo yekuvaka, uye zvinodiwa pakushanda, uye kugadziriswa pamwe chete nezvimwe zvikamu. Kuburikidza nekugadzira kwesainzi uye matekiniki ekuvaka akakodzera chete ndipo panogona kuwedzerwa mabhenefiti eHPMC uku ichidzivirira mhedzisiro yakaipa yekusakwana kwayo.
