Redispersible latex hmoov anti-caking tus neeg sawv cev yog cov tshuaj additive siv dav hauv teb xws li kev tsim kho, khoom noj, tshuaj thiab tshuaj pleev ib ce.Nws yog tsim los ntawm ib yam tshwj xeeb ntawm polymer uas yog soluble nyob rau hauv dej, tab sis thaum nws ntxiv rau ib tug qhuav mix, nws tsim ib tug hmoov uas resists caking.Lub hom phiaj ntawm tsab xov xwm no yog piav qhia txog cov txheej txheem kev npaj thiab daim ntawv thov zoo ntawm redispersible latex hmoov anti-caking tus neeg sawv cev.
Kev npaj:
Kev npaj ntawm redispersible latex hmoov anti-caking agents muaj ob peb kauj ruam.Txoj kev npaj dav dav tau piav qhia hauv qab no:
Kauj ruam 1: Aggregation
Thawj kauj ruam yog kev sib sau ua ke.Qhov no suav nrog condensation ntawm monomers los ua polymers.Cov txheej txheem polymerization tshwm sim nyob rau hauv lub reactor nyob rau hauv kev tswj kub thiab siab tej yam kev mob.Cov monomers maj mam ntxiv rau lub reactor thaum tswj qhov kub thiab txias ntawm qhov xav tau.
Kauj Ruam 2: Rov faib dua
Cov kauj ruam tom ntej yog rov ua dua.Qhov no suav nrog redispersing cov polymer hais mus rau hauv cov khoom me me, uas tom qab ntawd qhuav thiab hauv av rau hauv cov hmoov zoo.Cov txheej txheem redispersion suav nrog ntxiv emulsifiers, dej thiab surfactants rau cov khoom polymer.Cov sib tov yog ces stirred ntawm kev kub ceev nyob rau hauv ib tug homogenizer los yog siab homogenizer.Cov txheej txheem no rhuav tshem cov khoom loj polymer rau hauv cov khoom me me nrog qhov loj ntawm kwv yees li 0.1 microns.
Kauj Ruam 3: Qhuav thiab sib tsoo
Qhov thib peb kauj ruam yog ziab thiab sib tsoo.Cov redispersed polymer hais yog ces qhuav kom tshem tawm dej, tawm hauv cov hmoov.Cov hmoov yog tom qab ntawd hauv av mus rau qhov loj me me ntawm 10 thiab 300 microns.
Kauj Ruam 4: Anticaking Agent
Cov kauj ruam kawg yog ntxiv cov tshuaj tiv thaiv kab mob.Anti-caking agents yog ntxiv rau redispersible polymer hmoov los tiv thaiv lawv los ntawm agglomerating ua ke.Hom thiab ntau npaum li cas ntawm cov tshuaj tiv thaiv kab mob yog nyob ntawm daim ntawv thov ntawm cov tshuaj respersible polymer hmoov.
Qhov zoo ntawm daim ntawv thov:
Redispersible polymer hmoov anti-caking agents muaj ntau yam zoo dua lwm hom tshuaj tiv thaiv-caking.Cov txiaj ntsig no suav nrog:
1. Cov dej tsis zoo
Redispersible latex hmoov anti-caking cov neeg ua haujlwm yog cov dej resistant thiab tuaj yeem tiv taus ntev ntev ntawm cov dej noo tsis poob lawv cov txiaj ntsig.Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas cov khoom raug dej los yog cov av noo siab.
2. Siab thermal stability
Redispersible polymer hmoov anti-caking tus neeg saib xyuas muaj thermal stability, uas txhais tau hais tias nws muaj peev xwm tiv taus kub yam tsis muaj decomposing los yog poob nws cov hauj lwm zoo.Qhov no ua rau nws zoo tagnrho rau siv rau hauv daim ntawv thov qhov twg cov khoom raug raug kub.
3. Txhim khu kev ua kua
Anti-caking agents rau redispersible polymer hmoov txhim kho cov yam ntxwv ntws ntawm cov khoom hmoov, ua rau lawv yooj yim rau kev lis thiab koob.Qhov no ua rau nws zoo tagnrho rau kev siv hauv cov ntawv thov uas yuav tsum tau ntsuas qhov tseeb ntawm cov khoom, xws li kev tsim tshuaj thiab khoom noj.
4. Zoo adhesion
Redispersible latex hmoov los tiv thaiv thaiv cov neeg ua haujlwm muaj cov khoom nplaum zoo thiab yog qhov zoo tagnrho rau kev tsim kho cov khoom siv uas yuav tsum tau sib koom ua ke thiab ua raws li qhov chaw.
5. Kev nyab xeeb thiab kev tiv thaiv ib puag ncig
Lub redispersible latex hmoov anti-caking tus neeg saib xyuas muaj kev nyab xeeb thiab tus phooj ywg ib puag ncig.Nws tsis muaj cov tshuaj phem thiab tsis tso cov pa phem lossis cov tshuaj phem rau hauv ib puag ncig.
Redispersible latex hmoov anti-caking tus neeg sawv cev yog ib tug ntau yam tshuaj additives uas yog dav siv nyob rau hauv ntau yam lag luam.Nws yog npaj los ntawm ib tug series ntawm cov kauj ruam xws li polymerization, redispersion, ziab thiab sib tsoo, ua raws li los ntawm kev ntxiv cov tshuaj tiv thaiv-caking.Qhov zoo ntawm redispersible latex hmoov anti-caking tus neeg sawv cev muaj xws li dej tsis kam, siab thermal stability, txhim kho kev ua tau zoo, zoo adhesion, kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
