Water peita: ngā, kaihanga, hanganga

Industrial me toi peita taiepa, maha tuanui, wāhi papa, te taonga i roto i reira, me te matapihi, me te tatau whakaaro te tono i te peita i runga i te whakaehunga wai. peita taherapa, nga āhuatanga hangarau e whakarato he kapinga-ātete, me te-kounga tiketike tae, hi-tech me e kore pānga paitini i runga i kaiao ora.

Ngaahi Tefito'i Mo'oni o hanganga o te tiaki i te hanganga o te peita e hāngai ana te wai-

taherapa Taitara (he purara wai) mō ko e tika ana ki te aroaro i roto i tona ngarahu slurry hāngai wai-tahi hanga te whakaehunga. E konatunatua āhuatanga marara ki te reo wai, a ka kua hanga me te tīari i whakarara ki reira.

Ko te kupu, Kei roto te taherapa he filler, he thickener, me taherapa rongoā horoi.

Ko te matūriki polymer i muri i te wai kua maroke i runga i te mata te hanga i te apa kolirovanny flat. Ka taea te ngāwari nekehia atu ā peita Undried, me tona apa e kore kakara kino. Peita ātete ki te pānga aunoa, engari e kore e te tono ki mata whakarewa ki te ārai i te waikura i runga i te aroaro o te haumākū tonu.

Ko te āhuatanga hangarau matua o te peita e hāngai ana te wai-

Taherapa peita, te āhuatanga hangarau o nei - te pokey, rere auau, mahara motuhake , me te wa o te whakamaroke, kua he mahi production pūmau, tano e tano mo te maimoatanga o te papa ā-o whare noho.

Ko te tohu o te waimehatanga o te puranga waikano ki te wai ka mea whanganga pokey taupū e te whakamahi i te rheometer.

auau rere o te whakaehunga peita tei runga i te absorbency o te mata tangohanga, me te he i 100 ki te 200 ml ia mita tapawha o mata, waituhi paparanga oti te he kotahi mirimita matotoru.

Motuhake peita taherapa taimaha ko e pā ana ki 1.3 manokaramu ia rita.

Maroke te wā peita te taherapa, tei runga i te haumākū, me te pāmahana, mai i rua haora ki te ra kotahi. āhuatanga tino arotau whakaaro whakamaroke pāmahana rangi 20 degrees, me te 65% haumākū.

Ko te ora papa o nga peita whakaehunga ko nuinga o ti'aturi i runga i ona tikanga rokiroki (i roto i te pai - he wahi pouri hauhautanga), me te toharite o te 24 marama.

Taipitopito o te waituhi wai-purara te tino kitea i roto i te GOST raraunga 28196-89.

Whakatakotoranga GOST

Taherapa, tohutohu (GOST) e kua rēhitatia i raro i te tau 28196-89, kua huaina te reira i roto i te peita purara waiwai, ngā aukati o ngā uhi me taima, herehere i roto i te manene wai o waerau waihanga, e kua tapiritia ngā matū ngaahi houalotú pērā i te emulsifier, stabilizer me atu.

GOST 28196-89 whakakapi te tawhito GOST 19214-80 ko GOST 20833-75, TU 6-10-1260-87 TU 6-10-2031-85 TU 6-10-2054-86 TU 06.10.2081 -86 i runga i peita me varnishes. He fireproof peita wai-purara katoa, a ka ka taea ratou te hanga me te mahi anake i roto i te wāhi takoha-hā.

E ai ki a GOST, kia kawea ratou waka, me te rokiroki i roto i tarakh hiri i te pāmahana i runga 0 nekehanga, engari kua whakaaetia he taka wā poto i roto i te pāmahana ki te -40 nekehanga mo te kotahi marama.

Taherapa peita, whakaekea ana whakaritenga ona āhuatanga marama reflectance, rere production whakamāramatanga lightfastness - whakanohoia te wāhanga whakamātautau o te 24 haora te i raro i te rama motuhake, ka hoki 2 haora i roto i te pouri katoa, a ka whakaritea ki te tauira tohunga.

Āhuatanga o te whakamahinga o te wai-whakaehunga peita VEAK

Water peita VEAK, whakaritenga e he tetahi o te tika te nuinga mo te mahi haumaru me te tere i roto i te wāhi o te whare noho, optimally oreore mo hanga kāinga.

Ko reira ma, me te huinga o ngā uhi atu, me e taea te tiki e koe i tetahi tae e hiahiatia ana.

I roto i ia take kia tika i tona, me te maroke te mata - taua tikanga VAEK kohi ka iti iho i te 150 karamu ia mita tapawha. He pai ki te takoto ki raro, i runga i papa tawhito, me te kua pania reira, no te mea e he hāngai-taherapa me maroke i roto i te 4 hāora.

Mai VEAK - peita taherapa kiriaku, te āhuatanga hangarau tukua tona waimehatanga ki te wai, engari e kore e neke atu i te 10 ōrau o te rōrahi tuatahi. Whakamahia thinners matū e taea. āhuatanga o te peita tukua ki reira horoi i te papa pania ki te wai mahana, engari te horoi i te taputapu i reira whai tonu te otinga o te mahi.

I raro i ngā āhuatanga tino arotau, e kore e te mata pania ngaro te tae me te mauroa mō runga i 7 nga tau.

Āhuatanga o te whakamahi o PVA peita

Rite i roto i te kounga me te wā o te mahi, me te te huarahi o te tono peita he polyvinyl tāpia te taherapa, whakaritenga hangarau e tukua ki te whakamahi i te reira i roto i te tae o te papa ā-kore anake o te whare, engari ano hoki pepamārō, kahupapa, drywall me te rakau.

PVA peita ahi-ātete, engari tino wehi o te rerekētanga pāmahana me te haumākū. Tenei peita te taherapa, te āhuatanga hangarau e hanga i taua taea ki te whakamahi i te reira no te oti te mata, a na te mea te reira tino maroke hoki e rua haora.

Consumption o PVA whakaehunga peita ko e pā ana ki 200 milliliters ia mita tapawha, mo te peita i te wahi i ki faaohipa i te reira i roto i te maha o ngā paparanga. Nui atu i te tahi atu momo o te waituhi kohi me te hanganga motuhake hanga reira te utu atu mo te uara.

āhuatanga motuhake o te taherapa peita, "Teks"

A, no te kōwhiri i te momo o te hua peita me te kamupene kia utu ano tona whakarongo ki peita e hāngai ana te wai-"Tex". Ko te silikonomodifitsirovannuyu wai te āhuatanga umeraa Kaore e hāngai ana acrylate-e hōu ma, te kohi āhua me te haratau tono. Hoki i hanga e te reira i te whānuitanga ki tonu o kaiwaea.

Taherapa peita, "Teks", whakaritenga hangarau nei tukua ki te hoatu i te reira i runga i te pereki, raima, papa rakau, whakamahia hoki te maimoatanga o taiepa me tuanui; hanga reira he rererangi i runga i te kiriata Hāmā mahi e taea hau ki porotītiti noa i waenganui i te peita me te matotoru o te rauemi mata. Heoi, ko te rerekētanga matua, me te kitea o te peita "Tex" Ko tona wera tairongo - te rangi i roto i te ruma, ka whakamahi koe i te reira ki te kia mahana atu i +5 degrees.

te mau parau tumu General o te tiaki me te purenga o papa hipoki ki te wai-purara peita

Tetahi peita taherapa - hōroi; āhuatanga Hangarau o te waituhi kore e taea e anake ngāwari me hohoro tono ki te rauemi i runga i te mata poutū whakapae ranei o te te takai me te paraihe, engari ka hoki te wa roa ki te muru i te mata ki te kakahu haukū.

Hei pure i te taputapu hanga me te kakahu i taua peita te hoki whakamahia lather (mō te aukati polyvinyl tāpia); Me i ahatia peita whakaehunga kiriaku tuatahi matū - no te nui tango tere o te rohe e hiahiatia ana o te mata peita, tuatahi whakapiri i runga ki te pepa pepa ranei, maka ana ratou ki runga ki te māngaro gelatinous whakapiri pepapātū noa ranei.

Whakapai i te wahi o te mata o te kiriaku pea te whakamahi i te dryer whare me te matū - tahu whatiwhatinga o te mata, me te tango i to ratou mata.

He whakarewa matū hoki e tika ana mō te tango i peita e hāngai ana te wai-mā te whakarato i te pānga e totohu āta, engari emit ratou he kakara kino, me te e paitini ki te rauropi.

E rave rahi o te tūtohutanga i runga i te whakamahi o peita waterborne

I mua i te mahi ki te hiahia peita e hāngai ana te wai-ki te kia hāngai, raima, me te mea e tika ana zashpatlevat ngā mata katoa. Ahakoa te peita kaiao, tunu tonu koutou mo mōwhiti, he kanohi puehu me karapu.

Peita ngaueue Bank te, nga tirotiro i konatunatua, ka diluted ki te wai rite ki nga tohutohu. I zashpatlovannye taiepa tono peita e i roto i toru ngā papa i runga i te pepapātū - kotahi. tono te peita i roto i takai whakarara i te matapihi ki te taiepa. Ko te mea e whakamahia ana mo te paraihe tono, awa, Tāhorongia me spatulas.
