AnxinCel® HPMC mudhaka regypsum

Mukuvaka, gypsum mortar chinhu chakakosha chekushongedza uye kuenzana chine mashandiro akanaka ekuvaka uye mashandiro ekuchengetedza nharaunda. Zvisinei, gypsum mortar yakachena ine matambudziko akadai sekusanamira zvakanaka, kutsemuka, uye kuchengetwa kwemvura shoma, saka zvakakosha kugadzirisa mashandiro kuburikidza nekusanganiswa. Pakati pavo,AnxinCel® HPMC (hydroxypropyl methylcellulose)ine basa guru rekugadzirisa gypsum mortar semushonga wekuwedzera we cellulose ether unoshanda zvakanyanya.

1. Nhanganyaya kuAnxinCel® HPMC

AnxinCel® HPMC ipolymer isinganyungudike mumvura inowanikwa nekuchinja kwepolymer cellulose yechisikigo ne etherification. Ine kunyungudika kwakanaka, kugadzirisa viscosity uye kugona kudzivirira colloid. Mhando dzezvigadzirwa zvayo dzakapfuma mumhando dzakasiyana uye dzinogona kushandiswa kuma mortar systems pasi pemamiriro akasiyana ekuvaka, kunyanya muzvinhu zvakagadzirwa ne gypsum. Ine huwandu hwakawanda hwekushandisa.

2. Kushanda uye basa mu gypsum mortar

2.1. Kuvandudza kuchengetwa kwemvura uye kudzivirira kurasikirwa nemvura nekukurumidza uye kutsemuka

Zvinhu zveGypsum zvinooma nekukurumidza, uye panguva yekuvaka, zviri nyore kurasikirwa nemvura nekukurumidza nekuda kwekutorwa kwemvura nepasi kana kupwanyika kubva munzvimbo, zvichikonzera kutsemuka uye kusabatana zvakanaka. AnxinCel® HPMC inogona kugadzira chimiro chakafanana uye chakasimba che colloidal network mumota, ichinyatsovhara hunyoro uye inovandudza kuchengetwa kwemvura. Migumisiro yekuvandudzwa kwekushanda kwekuchengetedza mvura inosanganisira:

Iva nechokwadi chekuti gypsum inonyorovesa zvakakwana uye inovandudza simba rayo;

Deredza mitswe inokonzerwa nekurasikirwa nemvura uye kuderera kwemvura;

Kuvandudza mhedzisiro yekubatana nechigadziko.

2.2. Wedzera mashandiro ekuvaka uye nguva yekushanda

AnxinCel® HPMC inogadzirisa kugadzikana uye kuyerera kwemota kuti ipe mota kunzwa kuri nani kwekuvaka uye kushanda zvakanaka. Zvikuru sei, inoratidzwa seizvi:

Wedzera mafuta uye kuderedza kuramba kwekuvaka;

Wedzera nguva yekushanda kuti zvive nyore kugadzirisa zvinhu nevashandi vekuvaka;

Dzivisa kudonha kwemvura kana kudonha, kunyanya zvakakodzera pakuvaka madziro kana denga.

Kushanda uku kwakakosha zvikuru pakuvaka nekuvaka kwakakura munzvimbo dzine tembiricha yakakwira uye yakaoma, izvo zvinogona kuvandudza mashandiro uye kuderedza kudzokororwa kwebasa.

2.3. Gadzirisa kuenderana uye thixotropy kuti uvandudze mashandiro ekudzivirira kudonha

AnxinCel® HPMC ine thixotropy yakakura, kureva kuti, viscosity inoderera kana ichikurunga kana kudzvanya, uye inodzokera nekukurumidza kune yayo yekutanga mushure mekumira kukurunga. Hunhu uhwu hunoita kuti gypsum mortar iite fluid panguva yekuvaka, uye haisi nyore kuyerera kana kudonha mushure mekunamirwa pamadziro, izvo zvinovandudza zvikuru nyore uye kunaka kwekuvakwa kwefacade.

2.4. Kurudzira kusanganiswa kwakafanana uye kugadzikana

HPMC ine basa repamusoro uye inogona kuita basa rekupararira panguva yekukurunga, kuitira kuti zvikamu zvakasiyana-siyana zviri mudhaka rakaoma zvisanganiswe zvakaenzana, zvichidzivirira kupatsanurwa uye kuparadzaniswa kwezvinhu. Maumbirwo ayo akagadzikana emamorekuru anogonawo kuvandudza kugadzikana kwekuchengetwa kwedhaka regypsum uye kudzivirira matambudziko ekubuda kwemvura uye kudonha kwevhu.

2.5. Kuvandudza kunamira uye kunaka kwenzvimbo

Huwandu hwakakodzera hweAnxinCel® HPMC hunogona kuvandudza simba rekubatanidza pakati pe gypsum mortar nehwaro kana zvinhu zvinofukidza, izvo zvinobatsira kuti mortar ikwane zvakasimba mushure mekuvakwa uye isadonha nyore nyore. Panguva imwe chete, kuvandudzwa kwayo kwehunhu hwe rheological hwe slurry kunobatsirawo kuti pamusoro payo pave patete uye panyoro mushure mekushandiswa, zvichivandudza mhando yechigadzirwa chapera.

3. Mazano ekushandisa anokurudzirwa uye mushonga unokurudzirwa

Chiyero chinokurudzirwa cheAnxinCel® HPMC mu gypsum mortar chinowanzova 0.1%~0.3% (muupfu hwakaoma). Chiyero chaicho chinofanira kugadziriswa zvichienderana nemuenzaniso wechigadzirwa, nzvimbo yekuvaka, uye chimiro chemuto. Nzira yekuwedzera ndeyekusanganisa zvinhu zvisina kuoma nezvimwe zvinhu zveupfu hwakaoma kuti zvive nechokwadi chekuti kusanganisa kwakafanana.

Kushandiswa kweAnxinCel® HPMC mu gypsum mortarinogona kuvandudza zvakanyanya hunhu hwayo hwakakosha hwakadai sekuchengetwa kwemvura, kushanda zvakanaka, thixotropy, kudzivirira kudzika kwemvura uye kunamira. Sezvo kuvaka kwemazuva ano kuchiisa kudiwa kwakanyanya pakushanda kwemortar, HPMC, sechinowedzera chegirini, chine hushamwari kune zvakatipoteredza uye chinoshanda zvakanaka, iri kuva chinhu chakakosha uye chakakosha mumafomura emortar egypsum. Ichivimba netekinoroji yepamusoro yeR&D uye kudzora kwakasimba kwemhando, mhando yeAnxinCel® inopa mhinduro yakagadzikana uye yakavimbika yekuvandudza mashandiro ezvigadzirwa zvemortar yegypsum.
