Polyurea - he aha te mea te reira? waterproofing polyurea

Founga o coatings taatiraa me ngā āhuatanga hanganga kua roa kua wehea ki e rua ngā wāhanga: rauemi māori, me te waihanga. Oddly nui, i enei ra i reira tenei ano he wahi mo te rauemi raw tūturu, i te mea pai ki nga papanga waihanga nei mahi. Otiia ano i roto i te māngai o mua waihanga mō rauemi tuku iho i reira e maha kōwhiringa tika. I roto i tenei turanga raupapa me te polyurea. He aha te mea te reira, a reira he aha te hiahiatia - e kore e hāngai ana mō ngā kaihanga ngaio enei pātai mo te wa roa, engari kia matau reimana ohie ratou i roto i te taipitopito. Nā ki te mau huru ahurei o tenei rauemi waihanga hanga taea reira ki te mahi i-te kounga tiketike mātao, whakakapi te nuinga o nga taputapu maheni o te rōpū.

mōhiohio General e pā ana ki polyurea

Material Ko te waerau waihanga me tona hanganga rite polyurethanes, e kua synthesized e copolymerization o diisocyanates. Ko e mo'oni, te urunga ki te rōpū o elastomers me mau huru faaoti nohoia polyurea. He aha te mea i te wāhi o te tirohanga o te tono mahi? Ko te rauemi tuatahi ahei o hanga te paninga mārō, me te roa. Ko te tere o te pato'iraa tauhohenga ko tino nui, Heoi, hoki kia hiahia te hanga o ngā hua niao ki kia atu whakatikatika hangarau.

Ko tētahi atu āhuatanga o te rauemi waihanga e tika ana ki te nucleophilicity tiketike o amines. Tenei te tikanga e te hanganga o te hua oti iti tairongo ki makuku. Ko tenei huru, ka tāutuhia tetahi o nga mahi matua hoki i whakamahia i roto i te hanga o te polyurea paninga - wuru.

momo o te polyurea

Ka taea e tetahi te mea e, e toaati te rōpū katoa o waerau waihanga me te i roto i te tahi mau tikanga kia hanga whakarerekētanga ki tahi i te tahi. Heoi, i roto i te polyurea, i reira e rua momo faufaa rerekē: te pūhui memeka, me te kakara. Ko ngā te kē tuatahi i roto i taua taea te whakamahi i te reira ki te hanga i UV paninga ātete. e kore te mea haka Ie tukatuka polyurea i te puka o te paninga me e kore e ngaro tona tae i raro i te mana o te rā.

Ko te momo tuarua - polyurea kakara e taea te whakaaro rite te rauemi pūkenga. Ko te kupu, ki te ki te paninga tino tika tīmeka tiaki te tuanui, he tika ana mo te wuru o te turanga tenei whakatinanatanga, me rite ki te tikanga o te rongoā papa whakapaipai roto. I tua atu, whakamahia te wuru polyurea te tenei ra mo te hanga o te taputapu me te waka, me te i roto i te hanga o ngā tauārai tiaki ātete mō ngā teihana hurihiko me whakaurunga.

Kotahi-wae, me rua-wae

Hoki te māramatanga o tenei wehenga kia hanga ki te mau parau tumu o te tauhohenga polyurea. Ko te rauemi paerewa ko te hanganga e rua-wae, e mahi i raro i te mana o te whakakōkī. E ko, e te tukanga solidification wahi i te tikanga o te wāhanga pŭpŭ tauturu. Na ko reira e tika ana ki te whakatutuki i te pātai o te mea ko te polyurea-wae kotahi. He aha te mea i roto i te tukanga o te wuru coatings? Ko reira watea ki te tono i te rauemi, e kore e rapua e te whakakōkī mō te tauhohenga, arā, kawea te whātioatanga te i roto i takitahi, tuku ki a koutou kia tukatuka ā.

e mea he ngāwari ki te whakamahi i tito pana-wae me i te wahi tuatahi, e aki orotahi bicomponent atu ohie. Heoi, i roto i ngā o te kaha o te āhuatanga kei te huri i roto i te huarahi i te ritenga. kia whakamahia tito kotahi-wae hei tiaki pŭpŭ tauturu engari kawenga mō te tukanga wahi kia tono polyurea tikanga. Ki te taea te tono ona ringa, me te ki te-wae e rua, te mea matua - ki te whakamahi i ngā taputapu motuhake mō tenei whakaaro.

Urea hangarau waterproofing

He maha ngā huarahi i roto i i tono tenei momo o te wuru te. Tenei papa peihana tukatuka, hiritia turanga me tuanui o te tiaki wai. I roto i te nuinga o te wā, tono te paninga e runanga i te tikanga kahupapa. kia tika ki te whakaritenga o pikaunga i runga i te taupoki, awenga waho, a pera te tohu o te adhesion rerekētanga i roto i te huarahi. D. ano, kia whakamana ai wuru polyurea te whakamahi i te tito kotahi ranei e rua-wae. I roto i te mahi ki ngā pērā i turanga me ngā hanganga tuanui, he reira e minaminatia ki te whakamahi i te tikanga tuarua-momo, mai te āhuatanga mua kaha. Iti ātete ki tinana awe wuru taea te whakamahi hei paninga paruru ngaahi houalotú.

tukatuka ā-

Ka rite ki kua whakahuatia, mo te tukatuka motuhake e tika ana ake hanganga kotahi-wae. I mua i te rauemi tono kia diluted ki te polyurea wai. Heoi, kia te waimehatanga kia mahia anake i raro i tikanga o pokey iti. I roto i te tahi atu wā ko reira rawaka ki whakaoho te otinga mō te taurite te tae. I roto i te nuinga o te wā, e kore e polyurea tono ā-rapu whai wāhi o te taputapu motuhake ranei ētahi atu wāhanga pŭpŭ tauturu. Me te reira ki te kia tono e takai paraihe ranei. Otiia i roto i te mahi ki te papa whakarewa, he mea tika ki te whakamahi i te tämata. Kei te whakamahia hoki te reira i roto i te maimoatanga o ngā mata karaihe. I muri i te otinga o te wuru kotahi ra kia tatari ki te taupoki ana riro pakeke rawaka.

Tukatuka taputapu motuhake

kaihanga ngaio ki te faaineine i me te polyurea te rehu te whakamahi i ngā taputapu motuhake. I roto i ngā mo enei hiahia ngā wae mō te riringi coatings tuuraa i kuratini. Tikanga, tenei taputapu, whakahaere i te pēhanga tiketike, me te taea ki te rokiroki i te tekau nunumi tohutao mō polyurea. Ko te tauira hou o te taputapu mō te tono polyurea whakaratohia ki ngā waeine mahi mo te tātari o te ranunga tohu taumata mata tukinotia, mita rere, me te tahi atu whakaaro e whakarei hāneanea taputapu.

Ētahi atu tono

Ko te huinga o te pakeke, me te ātete ki te houku meinga polyurea whānui. O te akoranga, te tuatahi o te katoa e whakamahia ana e ia i roto i te hanga, me te oti mahi. Ko nga painga o te rauemi arotakea me te pahi kamupene, ngā toa auto hanga, hinonga mahi e rave nei i roto i te tautoko hangarau o ngā hanganga, piriti me tāke. He hoki nga painga o tenei rauemi hei insulator i. Hei matau i tēnei taonga ko utu te haamana'oraa i te whakahoki ki te pātai, polyurea - he aha te mea te reira. Tenei, runga ake katoa, nohopuku-tautuhinga polymer, e whakarato ana i te hiri, me te kaha whai hua. Ko, ki te te tukanga rite ki te apa mutunga mata Uwhi, ka taea, me te wareware i te piriti matao e.

mutunga

Ka rite ki rauemi hangarau hou katoa, polyurea mua o whakataetae tikanga o noho motuhake mo te utu. Ko te rauemi utu tenei, engari ko te hua ko te utu. Ko tētahi atu mea, ko te e hoki me te whakamahi whakamahi tūmataiti tono ā polyurea rite te hoko o te taputapu utu ka meinga koretake te whakamahi o tenei hangarau. I roto i te rerekē, i roto i te take o ngā nui-tauine kahore napyliteley mātao motuhake e kore e mahi i. tikanga dosing whakarato i te paninga kākahu, a ka whakaora i runga i ngā utu. kia hoki kia whanau te reira i roto i te ngakau e te hunga rerekē nga kaihanga polyurea, aua, a kia rerekē te mahi o te ngā waitohu.
