Umgubo ojikelezayo ngumgubo owenziwe kukumisa ukutshiza i-polymer emulsion, ekwabizwa ngokuba yirabha eyomileyo yomgubo. Le powder ingancitshiswa ngokukhawuleza kwi-emulsion emva kokudibana namanzi, kwaye igcinwe iipropathi ezifanayo kunye ne-emulsion yasekuqaleni, oko kukuthi, ifilimu iya kwenziwa emva kokuphuma kwamanzi. Le filimu inokuguquguquka okuphezulu, ukumelana nemozulu ephezulu kunye nokumelana okuhle kwimigca eyahlukeneyo. Umgca wokudibanisa ophezulu.

I-rexx ye-latex ephinda isetyenziswe ikakhulu kwimimandla yolwakhiwo efana nokufakwa ngaphakathi kodonga, ukuqinelana ngetayile, unyango lwefestile, igypsum, i-stucco jypsum, ulwakhiwo lwangaphakathi kunye noludwe lwangaphandle lodonga, udaka oluhonjisiweyo, njl njl. amathemba.

Ukunyusa kunye nokusetyenziswa komgubo we-latex ophuculiweyo uphucule kakhulu ukusebenza kwezixhobo zokwakha zemveli, ziphucule kakhulu umanyano, umanyano, amandla e-flexural, ukumelana nefuthe, ukumelana ne-abrasion, ukuhlala ixesha elide, njl njl. Yenza iimveliso zokwakha ngomgangatho wazo ogqwesileyo kunye nomgangatho ophezulu wokuqinisekisa umgangatho weeprojekthi zokwakha.

Umgubo ophindayo

Okwangoku kusetyenziswa umgubo wepolymer osasazekayo osetyenziswayo kwihlabathi liphela: Umgubo werabha we-copolymer (VAC / E / VeoVa), ezi ntlobo zintathu zomgubo wepolymer onganyangekiyo ulawula imarike, ngakumbi i-vinyl acetate kunye ne-ethylene copolymer irabha powder VAC / E, inesikhundla esiphambili kwicandelo lehlabathi, kwaye imele iimpawu zobuchwephesha zokuphinda zisebenze umgubo. Ukusuka kumava obuchwephesha bokusebenzisa iipolym eziguqulwe ngodaka, isisona sisombululo sisiso sobugcisa:

1. yenye yezona polima zisetyenziswa kakhulu emhlabeni;

Amava amaninzi esicelo kwicandelo lokwakha;

3. Inokudibana nepropathi yerheological efunwa ngodaka (Oko kukuthi, ukusebenza okufunekayo);

4. I-resin ye-Polymeric kunye nezinye i-monomers ineempawu zezinto eziphantsi eziphilayo (VOC) kunye negesi ephazamisayo ephantsi;

5. Inempawu zokumelana kakuhle kwe-UV, ukumelana nobushushu obuhle kunye nokuzinza kwexesha elide;

I-6, ngokuxhathisa okuphezulu kwi-saponification;

I-7, inoludwe lwamaqondo obushushu agqithisileyo ebanzi (Tg);

8. Inolungelelwaniso olufanelekileyo ngokugqibeleleyo, ukuguquguquka kunye neepropathi zoomatshini;

9. Unamava amade kwimveliso yemichiza kunye nendlela yokugcina uzinzo ekugcineni imveliso ekumgangatho ophezulu;

Kulula ukudibanisa ne-colloid yokukhusela (i-polyvinyl alcohol) yokusebenza

Umzobo 1 ngumfanekiso we-powder redispersible ethengiswa kwintengiso

Iimpawu zomgubo redispersible

1. Umgubo werhasi ngumgubo onganyibilikiyo ongenakususwa ngamanzi. I-copolymer ye-ethylene kunye ne-vinyl acetate, kunye ne-polyvinyl yotywala njenge-colloid yokukhusela.

2. I-VAE redispersible latex powder inepropathi eyakha ifilimu, i-50% isisombululo samanzi senza i-emulsion, kwaye yenza ifilimu efana neplastiki emva kokubekwa kwiglasi iiyure ezingama-24.

3. Ifilimu eyenziweyo inokuguquguquka okuthile kunye nokuxhathisa kwamanzi. Inokufikelela kwimigangatho yesizwe.

I-4.Redispersible latex powder has a high performance: has high bonding uwezo kunye nokusebenza okungafaniyo, ukuchasana kwamanzi okumandla, amandla afanelekileyo okuqinisa, kwaye inika udaka ukuxhathisa okuphezulu kwe-alkali, okunokuphucula ukubambelela komdaka kunye namandla eguquguqukayo ukongeza kwi-plastiki, ukunxiba ukumelana kunye nokusebenza, kuye kube bhetyebhetye olomeleleyo kudaka oluqhekekayo.

Ukusetyenziswa komgubo we-latex odibeneyo kwisidaka esomileyo somgubo:

Mort Umdaka wokwakha kunye nodaka lodaka: I-latex redispersible powder ine-impermeability elungileyo, ukugcinwa kwamanzi kunye nokuqina okungafunekiyo, kunye namandla aphezulu wokubopha, anokusombulula ngokufanelekileyo ukuqhekeka kunye nokungena okukhoyo kudaka lwendabuko. Neminye imiba esemgangathweni.

Mort Umgangatho wokulinganisa kunye nomgangatho womgangatho: Umgubo werhasi onokuphinda unamandla amakhulu, umanyano olulungileyo, ukunamathela kunye nokuguquguquka okufunekayo. Inokuphucula ukubambelela, ukumelana ne-abrasion kunye nokugcinwa kwamanzi kwezixhobo. Inokuzisa i-rheology egqwesileyo, ukusebenza kunye nokusebenza okungcono kakhulu kokuzilungisa kumgangatho wodaka lokulinganisa kunye ne-screed.

Ukuncamathela kwethayile, iarhente yokudibanisa iithayile: I-latex redpersible powder ine-adhesion elungileyo, ukugcinwa kwamanzi okuhle, ixesha elide elivulekileyo, ubhetyebhetye, ukumelana ne-sag kunye nokumelana okuhle nomkhenkce. Inokuzisa ukubambelela okuphezulu, ukumelana nesiliphu kunye nokusebenza kakuhle kolwakhiwo kwi-tile yokuncamathelisa, ukunamathela kumaleko omncinci kunye nokugcwalisa ngokudibeneyo.

Mort Udaka olungafakwanga manzi: Umgubo oxutywe ngokutsha we-latex uyawomeleza amandla e-bond kuwo onke amasuntswana, unciphisa imodyuli ye-elastic, unyusa ukugcinwa kwamanzi, unciphise ukungena kwamanzi, kwaye unike iimveliso ngokuguquguquka okuphezulu, ukuxhathisa kwemozulu ephezulu kunye neemfuno zokulwa kwamanzi amaninzi. Inomphumo wexesha elide inkqubo yokutywina kunye neemfuno zokukhutshwa kwamanzi kunye nokuxhathisa kwamanzi.

Mort Udaka lwangaphandle lokugquma udonga: I-emulsion yomgubo ongagudlukiyo kwinkqubo yangaphandle yokwambathisa eludongeni yonyusa umanyano lodaka kunye namandla okubopha kwibhodi yokugquma, ukuze ukwazi ukufuna ubushushu ngelixa unciphisa ukusetyenziswa kwamandla. Ukufikelela ekusebenzeni okuyimfuneko, amandla eguquguqukayo kunye nokuguquguquka kwimveliso yangaphandle yofakelo lodonga lwangaphandle, unokwenza iimveliso zakho zodaka zibe nokusebenza okuhle kwebhanti kunye noxinzelelo lwezinto zokufakelwa kunye nesiseko. Kwangaxeshanye, kuyanceda ekuphuculeni ukuxhathisa kwempembelelo kunye nokumelana nomphezulu wokuqhekeka.

A Ukulungisa i-Mortar: Ukuphinda ufumane umgubo we-latex unakho ukuguquguquka okufunekayo, ukubetheka, ukuqinelana okuphezulu, amandla aguqukayo kunye nokuqina. Yenza udaka lokulungisa luhlangabezane nezi mfuno zingasentla zokulungisa ikhonkrithi eyakhiweyo nengacwangciswanga.

I-Interface Mortar: I-latepersible powder powder isetyenziselwa ukuphatha umphezulu wekhonkrithi, ikhonkrithi ene-lime, isitena sesanti kunye nokubhabha izitena zomlotha, njl., Ukusombulula ingxaki yokuba ujongano alukho lula ukunamathela ngenxa yokufunxwa kwamanzi okanye ukuguda , kwaye umaleko wokutyabeka awunanto. Igubu, ukuqhekeka, ukuchuba, njl.njl.Lenza ukubambelela komelele, akukho lula ukuwa kunye nokumelana namanzi, kunye nokumelana okuhle kakhulu komkhenkce. Inomphumo obalulekileyo ekusebenzeni ngokulula, ulwakhiwo olululo.

Umgubo ojikelezayo usetyenziswa ikakhulu kwi:

Ngaphakathi nangaphandle kwe-putty powder, i-tile yokuncamathela, iarhente yokudibanisa ithayile, iarhente yomdibaniso womgubo owomileyo, udaka lwangaphandle lokugquma, udaka oluzimeleyo, ukulungisa udaka, udaka lokuhombisa, udaka olungangenwa ngamanzi kudaka lwangaphandle olomileyo oluxubileyo. Onke amatyhubhu asetyenziselwa ukuphucula ubungangamsha kunye nemodyuli ephezulu yokukhanya kwesamente, nokubanika ukuguquguquka okungcono kunye nokuqina okuqinileyo kwendibaniselwano ukumelana nokulibazisela isizukulwane sokungafuneki kwamadaka esamente. Kungenxa yokuba ipolymer kunye nodaka ziyisakhiwo sothungelwano olungenelelayo, ifilimu eqhubekayo yecolymer yenziwa kwii-pores, ezomeleza ulwalamano phakathi kwezinto ezihlanganayo kunye nokuthintela ezinye zeepores zodaka. Ke ngoko, udaka oluguqulweyo emva kokuqina lube nokusebenza okungcono kunodaka lwesamente. Kubekho uphuculo olukhulu.
