Kupinda kuri nyore kumakona nemagapu.Nekuda kwekushandiswa kwekudzvanyirira kwakanyanya uye kupfapfaidza pasina mweya, pendi yekupuruzira haina mweya, uye pendi inogona kusvika nyore kumakona, mapundu uye zvikamu zvisina kuenzana, kunyanya kune zvivako zvehofisi zvine mhepo yakawanda uye pombi dzekudzivirira moto.
High viscosity coatings inogona kupfapfaidzwa, nepo bhurasho remaoko uye kupfapfaidza mweya zvinongoshanda kune yakaderera viscosity coatings.Nekuvandudzwa kwehupfumi uye shanduko yemafungiro evanhu, zvave fashoni kushongedza madziro nepakati uye yepamusoro-giredhi yemukati uye yekunze madziro machira panzvimbo ye mosaics uye ceramic tiles munyika.
Emulsion pendi yemvura yave inonyanya kufarirwa mukati uye kunze kwemadziro ekushongedza zvinhu nekuda kweiyo isiri-chepfu, kuchenesa kuri nyore, ruvara rwakapfuma uye pasina kusvibiswa kwezvakatipoteredza.Asi emulsion pendi imhando yependi yemvura ine high viscosity.Panguva yekuvaka, vagadziri vese vane zvirambidzo zvakanyanya pakuderedzwa kwependi yepakutanga nemvura, kazhinji 10% - 30% (kunze kweiyo yakakosha yekuputira iyo inogona kuwedzera imwe mvura shoma isingakanganise mashandiro ekuputira, ayo anozonyorwa. mubhuku rezvigadzirwa).
Kuwedzeredza dilution kunozotungamira mukuumbwa kwemafirimu kwakashata, uye magadzirirwo ayo, kukwesha kuramba uye kusimba zvichakuvadzwa kune akasiyana madhigirii.Iyo dhigirii yekukuvadza yakanangana neiyo dilution, ndiko kuti, iyo yakakura dilution, yakaipisisa kunaka kwefirimu.Kana iyo dilution zvinodiwa zvemugadziri zvakanyatsoteedzerwa, iyo viscosity yepende ye emulsion yakanyanya kukwirira uye kuvaka kwakaoma.Kana iyo roller coating, brush coating kana air spraying inoshandiswa pakuvaka, pendi mhedzisiro yakaoma kugutsikana.Munyika dzekunze, nzira inonyanya kufarirwa ndeyekushandisa mushini wekupfapfaidza usina mweya usina mhepo pakuvaka.
Latex pendi kazhinji haina organic solvents.Iyo haina chete isina kunyungudika kwemhepo panguva yekugadzira uye kuvaka, asi zvakare haina kusvibiswa kune yakapoteredza nharaunda, uye kuburitswa kweiyo organic volatiles panguva yekushandiswa kwakaderera kwazvo.Huwandu hwese hweVOC (organic volatile matter) kazhinji huri mukati meiyo inotenderwa chiyero.Iyo yakachengeteka, yehutsanana uye yezvakatipoteredza inoshamwaridzana yakasvibira chivakwa chekushongedza coating.
Iyo yemvura-based emulsion pendi ine mhepo yakanaka yekupinda uye yakasimba alkali kuramba.Nokudaro, hazvisi nyore kuputika kana pane musiyano mukuru pakati pehunyoro hwemukati nekunze kwekuputira, uye kuvhara hakusi nyore "kutuka" mumba.Inonyanya kukodzera kupenda pamusoro pesimenti uye plaster pamusoro pemadziro emukati uye kunze kwezvivakwa.Latex pendi inoshandiswa zvakanyanya kushongedza mukati nekunze kwemadziro ezvivakwa nekuda kwekusiyana kwayo, ruvara rwakapenya, huremu huremu uye nekushongedza kwekuvaka nekukurumidza.
