Nzira yekuziva sei kunaka kwe redispersible polymer poda?

chekutanga. Tanga wanzwisisa kuti chiiredispersible polymer poda.

Dispersible polymer powders mapolymer ehupfu akaumbwa kubva ku polymer emulsion kuburikidza neiyo chaiyo yekupfapfaidza kuomesa maitiro (uye kusarudzwa kweakakodzera ekuwedzera). Iyo yakaoma yepolymer poda inoshanduka kuita emulsion kana yasangana nemvura, uye inogona kupera mvura zvakare panguva yekubatana uye kuomesa dhaka, kuitira kuti zvimedu zvepolymer zvigadzire chimiro chemuviri wepolymer mudhaka, inofanana nekuita kwekuita iyo polymer emulsion, iyo inogona kuvandudza simende dhaka. kuita zvepabonde. Emulsion dry powder modified mortar inodaidzwa kuti dry powder mortar (inozivikanwawo sedhaka rakaoma rakasanganiswa, dhaka rakaoma rakasanganiswa). Sezvo hupfu hwakaoma husingadi kutarisa emulsion kuumbwa uye kugadzikana semapolymer emulsions, zvishoma zvekusanganiswa zvinogona kuita kuti dhaka rizadzise zvinhu zvinodiwa, uye ine zvakanakira kurongedza nyore, kuchengetedza, kutakura uye kupa kupfuura emulsions, antifreeze uye kwete. mold kukura, Dambudziko remabhakitiriya mhenyu, uye mukana wekuti inogona kugadzirwa mune imwe-chikamu chigadzirwa neyakagadzirira-musanganiswa packaging senge simende nejecha, uye inogona kushandiswa mushure mekuwedzera mvura.

Paunenge uchinyorera, sanganisa uye rongedza jecha, simende, emulsion yakaoma poda uye zvimwe zvekuwedzera zvekuwedzera, uye zvinongoda kuwedzera imwe huwandu hwemvura panguva yekuvaka-panzvimbo yekugadzira dhaka rakaoma reupfu nekuita zvirinani. Nheyo yekugadzirwa kwekuoma emulsion powder ndeyekuti mapolymer particles mushure mekupararira kwelatex powder anoratidza hukuru hwechidimbu kana chidimbu chekupararira kwakafanana neyekutanga emulsion polymer particles. Imwe chiyero chekudzivirira colloid yakadai se polyvinyl doro inofanira kuwedzerwa kune emulsion, kuitira kuti latex powder inogona kuparadzirwa zvakare mu emulsion kana inosangana nemvura. Chete nechakanaka dispersibility inogona iyo latex poda inowana yakanakisa mhedzisiro. . Iyo inorasika yepolymer hupfu inowanzo chena hupfu. Zvisungo zvayo zvinosanganisira:

Polymer resin: Inowanikwa mukati mechikamu cheiyo rabha poda zvimedu, uye zvakare ndicho chinhu chikuru cheiyo redispersible polymer hupfu.

Kuwedzera (mukati): pamwe chete neresin, inoita basa rekugadzirisa resin. Zvinowedzerwa (zvekunze): Zvimwe zvekushandisa zvinowedzerwa kuti uwedzere kuwedzera mashandiro eiyo inorasika polymer poda.

Protective colloid: chidimbu che hydrophilic material yakaputirwa pamusoro pezve dispersible latex powder particles, iyo inodzivirira colloid yeakawanda redispersible latex powder is polyvinyl alcohol.

Anti-caking agent: yakanaka mineral filler, inonyanya kushandiswa kudzivirira hupfu hwerabha kubva pakubika panguva yekuchengetedza uye yekufambisa uye kufambisa kuyerera kwehupfu yerabha (yakakandwa kubva mumabhegi emapepa kana matangi.)

Nzira yekuziva sei kunaka kwe redispersible latex powder?

Nzira 1, nzira yemadota

Tora imwe huwandu hwehupfu hwelatex hunogona kudzokororwa, woiisa mumudziyo wesimbi mushure mekuyera, kupisa kusvika kumadhigirii anenge 500, mushure mokupisa pahupamhi hwepamusoro hwe500 degrees, itonhodze kusvika kune tembiricha yekamuri, uye uremu zvakare. Chiedza chechiedza uye unhu hwakanaka.

Nzira yechipiri, nzira yekubvisa

Tora humwe huwandu hwehupfu hwelatex hunogona kudzokororwa uye uinyunguduse mu5 nguva yehuwandu hwemvura, fambisa zvakanaka uye rega imire kwemaminitsi mashanu usati waona. Muchidimbu, izvo zvishoma zvinosanganisirwa zvinogara muchikamu chepasi, zviri nani kunaka kweiyo redispersible polymer hupfu. Iyi nzira iri nyore uye iri nyore kuita.

Nzira yechitatu, nzira yekugadzira firimu

Tora humwe hunhu hwelatex powder inodzokororwa, nyungudusa kaviri mumvura, kurunga zvakaenzanirana, rega imire kwemaminetsi maviri, kurunga zvakare, dururira mushonga pagirazi rakachena, woisa girazi panzvimbo ine mhepo ine mumvuri. . Bvisa kana wanyatsooma. Tarisa iyo yakabviswa polymer firimu. Kujeka kwepamusoro uye kunaka kwakanaka. Wobva wadhonza zvine mwero, zvine elasticity yakanaka uye mhando yakanaka. Iyo firimu yakabva yagurwa kuita mitsetse, yakanyudzwa mumvura, uye yakaonekwa mushure mezuva 1, kunaka kwefirimu kwaisanyanya kunyungudika mumvura. Iyi nzira ine chinangwa chakawanda
