Nhau

Sezvo viscosity yemvura-yakavakirwa mvura yakaderera, haigone kusangana nezvinodiwa zvekuchengetedza uye zvekuvaka zvekuchengetera, saka zvinodikanwa kuti ushandise iyo yakakwenenzverwa, kuti ishandise yakakodzera thickener yekugadzirisa iyo yekukonzeresa mvura yekubatanidza mvura-yakavakirwa mvura.

Kune akawanda marudzi emarobhoti. Paunenge uchisarudza manhau, mukuwedzera kune yavo yekubudirira kugona uye kutonga kweanorongedza rheology, zvimwe zvinhu zvinofanirwa kufungwa nekuita kuti kuunganidza kuve nekudyidzana kwekuvaka, kuzivikanwa kwefirimu yefirimu uye hupenyu hwakareba hwebasa.

Iko kusarudzwa kwemarudzi akashata kunonyanya kuve kwakavakirwa pane zvinodiwa uye mamiriro chaiwo ekuumbwa.

Paunenge uchisarudza uye kushandisa manhara, izvi zvakakosha.

1. Yakakwira molecular uremu hec ine dhigirii rakakura rekupinda mukati mekuratidzira yakaderera molecular uremu uye kuratidzira hukuru hwekubudirira pakuchengetedza panguva yekuchengetedza. Uye apo iyo chiyero chesafura ichiwedzera, iyo mhepo yemhepo inoparadzwa, iyo yakakura shear chiyero, iyo madiki mhedzisiro yemanyorerwo euremu pane viscosity. Iyi nzira inosimbisa haina chekuita neyekuita neyekuita zvinhu, zvinowedzera zvinoshandiswa, zvinongoda kusarudza uremu hwechinguvana

2.HEUR thickener is a viscous aqueous solution with diol or diol ether as co-solvent, with solid content of 20%~40%. Basa reCo-solvent ndeyekudzivisa kudenhamira, kana zvisina kudaro mitezo yakadaro iri mune yeGel State pachigadziko chimwe chete. Panguva imwecheteyo, iko kuvapo kweSolven kunogona kudzivirira chigadzirwa kubva pakusununguka, asi chinofanira kudziyirwa munguva yechando usati washandisa.

3. Yakaderera-yakasimba, yakaderera-viscosity zvigadzirwa zviri nyore kurasa uye inogona kutakurwa uye inochengeterwa muhuwandu. Naizvozvo, mamwe muhedheni ane hukama hwakasiyana-siyana hwakasimba hwechigadzirwa chimwe chete. Iyo CO-solvent yezvinyorwa zvekuvhara yakakwira, uye yepakati-shear viscosity ye pendi ichave yakaderera kana ichishandiswa nekudzora iyo co-solvent yakawedzera kumwe kuumbwa.

4 Paunenge uchishandisa yakakwira viscossity zvigadzirwa, iyo thickener inoda kuti isimbe nemusanganiswa wemvura uye co-solvent isati yawedzerwa. Kana iwe ukawedzera mvura kuti ubvise zvakananga, inoderedza kusunganidzwa kweiyo yekutanga ku-solvent mune chigadzirwa, iyo ichawedzera kuderera uye kukonzera visikopa kuti isimuke.

5. Kuwedzera thickener kune tangi yekusanganisa inofanira kunge yakatsiga uye inononoka, uye inofanira kuiswa parutivi rweusvingo. Kumhanya kwekuwedzera hakufanirwe kutsanya zvekuti iyo svutugadzike inogara pamusoro pemvura, asi ichakwevera pasi yakatenderedza shaft inomhanya, kana ikasasanganiswa nemazvo kana iyo svutugadzike ichanyanya kuoma kana yakarongedzwa nekuda kwekusangana kwepamusoro.

6. Heur thickener inowedzerwa kune iyo pendi inosanganisa tangi mushure meimwe zvikamu zvemvura uye pamberi pe emulsion, kuitira kuti uve nechokwadi chehuwandu hwepasi.

7. Hase manhamba anowedzerwa zvakananga kune iyo pendi muchimiro che emulsion mukugadzira kwembolsion kupenda pasina kusimuka kana pre-kusarerekera. Inogona kuwedzerwa sechinhu chekupedzisira mune yekusanganisa chikamu, mune pigment yekupararira chikamu, kana sechikamu chekutanga mukuvhengana.

8. Sezvo Hase iri yakakwirira acid emulsion, mushure mekuwedzera, kana paine alkali mumelsion pendi, ichakwikwidza iyi Alkali. Naizvozvo, zvinodikanwa kuti uwedzere hana yehukama

9. Alkali inogona kuwedzerwa pamberi kana mushure mekunge awedzera mumiririri anowedzerwa. Kubatsira kwekuwedzera kusati kwamboita kuti kusavimbika kwekuparadzwa kwenguruve kana emulsion binder ichakonzerwa neyekukwenenzverwa neyekubata alkali kubva pamusoro peiyo pigment kana binder. Kubatsira kwekuwedzera Alkali mushure meiyo iyo Stickener yakapararira isati yazvimba kana yakanyungudutswa neAlkali, zvichienderana nekuumbwa, maitiro uye maitiro uye maitiro ekugadzira. Iyo nzira yakachengeteka ndeyekudzora iyo inoyevedza matani nemvura kutanga uye wozozvirega neAlkali pamberi.

10. Hase Thickener anotanga kuzvimba nePH kweanenge 6, uye nekubudirira kwekubudirira kunouya mukutamba kuzere paPH kweanosvika , nokudaro simbisa kugadzikana kwe viscosity.
