Putty rudzi rwezvinhu zvekushongedza chivako. Rutivi rweputty chena pamusoro peimba isina chinhu rwuchangobva kutengwa runowanzova ruchena kupfuura 90 uye rutete kupfuura 330. Putty yakakamurwa kuita madziro emukati nemadziro ekunze. Putty yekunze inofanira kudzivirira mhepo nezuva, saka ine guruu rakawanda, simba rakawanda uye indekisi yekudzivirira nharaunda yakaderera. Indekisi yakazara yeputty yemadziro emukati yakanaka, ine hutano uye inodzivirira nharaunda, saka madziro emukati haashandiswi kunze uye madziro ekunze haashandiswi mukati. Kazhinji putty yakagadzirwa negypsum kana simende, saka pamusoro payo pakaoma uye zviri nyore kuisunga zvakasimba. Zvisinei, panguva yekuvaka, zvichiri kudikanwa kuisa layer ye interface agent pa base course kuti ivhare base course, uye kuvandudza kunamira kwemadziro, kuitira kuti putty ikwanise kubatanidzwa zviri nani ne base place.
Huwandu hweHPMC hunoshandiswa hunoenderana nemamiriro ekunze, musiyano wekupisa, mhando yeupfu hwecalcium ash hwemunharaunda, nzira yakavanzika yekubika putty powder uye "mhando inodiwa nemushandisi". Kazhinji, pakati pe4kg ne5kg.
HPMC ine basa rekunyorovesa, izvo zvinogona kuita kuti putty powder ishande zvakanaka. Hydroxypropyl methylcellulose haibatanidzwi mune chero compound reaction, asi inongobatsira chete. Putty powder imhando yecompound reaction pamusoro pemvura nepamadziro,
Mamwe matambudziko:
1. Kubviswa kweputty nehupfu
A: Izvi zvine chekuita nechiyero checalcium ye lime, uye zvine chekuitawo nechiyero uye mhando ye cellulose, iyo inoratidzwa muchiyero chekuchengetedza mvura chechigadzirwa. Mwero wekuchengetedza mvura wakaderera uye nguva yemvura yecalcium ye lime haina kukwana.
2. Kubvisa nekumonera upfu hweputty
A: Izvi zvine chekuita nekuchengetwa kwemvura. Kuwanda kwe cellulose viscosity kwakaderera, izvo zviri nyore kuwana kana kuti chiyero chacho chidiki.
3. Poindi yepoda yeputty
Izvi zvine chekuita ne cellulose, iyo ine hunhu husina kunaka hwekuumba firimu. Panguva imwe chete, tsvina iri mu cellulose ine kamuitiro kadiki ne ash calcium. Kana kamuitiro kacho kakanyanya, putty powder inoratidza mamiriro e tofu residue. Haikwanise kuenda kumadziro uye haina simba rekubatanidza. Pamusoro pezvo, inowanikwawo muzvigadzirwa zvakaita se carboxy groups dzakasanganiswa mu cellulose.
