He turuturu? Me pēhea te āwhina a ngā kaiwhakaoho polyurethane amine

Me whai otinga matatau mō ngā turuturu wai uaua i roto i te raima me te pereki. He nui te pānga pūtea o ēnei take.

E ai ki te American Insurance Association, neke atu i te $10 piriona te ngaronga o ngā rawa i ia tau nā te turuturu o te wai.

Kei roto i ngā kūmara polyurethane hou te whakautu. Ka whakamahia e ēnei pūnaha he mea motuhakeNgā Whakakōkī Amine Polyurethanepērā i te Dimethylaminoethoxyethanol (DMDEE). Mā tēnei matū matua ka taea e te grout te tauhohe wawe ki te wai. Ka whānui ina pa atu, ka hanga he hiri pumau, ngāwari, ā, he ātete wai hoki ki te wāhi e tino hiahiatia ana.

He aha te DMDEE, ā, he aha i waiho ai hei Whakakōkī Pai Rawa?

Dimethylaminoethoxyethanol (DMDEE)koia te miihini e taraiwa ana i ngā kūmara polyurethane mahi-teitei. He whakakorikori motuhake e whakahaere tika ana i te tauhohenga matū e hiahiatia ana hei aukati i ngā turuturu. Mā te mārama ki tōna tūranga me ōna āhuatanga ka kitea he aha i pai ai tēnei mō te āraiwai ngaio.

Te Mārama ki te Tūranga o te DMDEE

He whakakorikori amine tuatoru te DMDEE. Ka whakamahia e ngā tohunga ēnei momo Whakakorikori Amine Polyurethane hei whakahaere i te tere me te kounga o tepahuka polyurethanetauhohenga. I roto i te whakakī wai, ko te mahi matua a DMDEE he tīmata i tētahi tauhohenga tere ina tūtaki te wai ki te wai. Mā tēnei ka whakarite kia tere te horapa o te wai hei whakakī i ngā kapiti me ngā āputa. Heoi, māna tēnei tauhohenga e whakahaere. Kāore te tukanga e tere rawa. Mā tēnei taurite ka taea e te pahuka te hanga i tētahi hanganga matotoru, ōrite, ka hanga he hiri pono ake, pumau ake hoki.

Ngā Āhuatanga Matū Matua me ngā Painga

Nā te hanganga matū o te DMDEE he painga motuhake tēnei. He tino pai ōna āhuatanga mō te hanga i tētahi arai pakari, ātete-wai.

He mea nui tōna urunga katoa ki te wai. Mā tēnei āhuatanga ka whai hua te mahi a te matū whakakorikori i te wā tonu ka werohia te kūmara ki roto i te taiao mākū.

Ki te whakaritea ki ētahi atu whakakōkī amine, he pai ake te mahi a te DMDEE, ā, he pai hoki mō ngā tono ārai wai uaua.

Mā te titiro ki tana mahi ki ētahi atu whakakorikori ka kitea tēnei āhua taurite:

He taurite te roa o te wā whakapūkara me te wā piki o te kirīmi e tukuna ana e te DMDEE, kia pai ake ai te whakahaere a ngā tohunga hangarau i te wā e pania ana, ki te whakaritea ki ngā whakakorikori kaha rawa.

Ko ngā painga matua o te DMDEE ko:

• Tauhohenga Taurite:He tere tauhohenga taurite tōna. Mā tēnei ka karohia te hanganga kiri ngoikore me ngā pūtau kore taurite i puta mai i ngā whakakorikori tino tere.
• Te Kōwhiringa Wai Teitei:Ka tauhohe te nuinga ki te wai. Mā tēnei arotahi ka whakaitihia te whakapūpū wawe, ā, ka pai ake te hanganga o te pahuka.
• Kounga Pahuka Pai Rawa:Mā te tauhohenga whakahaere ka puta he pumau o te pūtake me ngā pūtau ōrite hei hanga i tētahi hiri pakari, roa hoki te mau.

Te Mana o ngā Whakakōkī Amine Polyurethane i roto i te Grouting

Ngā whakakorikori amine polyurethaneKo rātou te kaha akiaki i muri i ngā grout ātete wai whai hua. Ka hurihia e rātou te kapia wai hei pahuka totoka, ārai-wai. Ko ngā āhuatanga motuhake o te whakakorikori e whakatau ana i te tere, te hanganga, me te pakari o te hiri whakamutunga. Mā te whakakorikori kounga teitei pēnei i te DMDEE ka whakarite kia pono te mahi a te grout i raro i ngā āhuatanga uaua, inā koa ka aukati i ngā turuturu kaha.

Me pēhea te whakaterenga a te DMDEE i te tukanga hiri

Ka whakaratohia e te DMDEE te urupare tere e hiahiatia ana hei aukati i te rere o te wai i roto i ōna ara. Ina werohia e te tohunga hangarau tete kūmara polyurethaneki roto i te kapiti mākū, ka tīmata tonu te tauhohenga matū ki te wai e te whakakorikori DMDEE. He tere, he whakahaere hoki tēnei tukanga, e āhei ai te hiri tino whai hua.

Ka puta te mahi hiri i roto i tētahi raupapa mārama:

1. Werohanga:Ka werowerohia tika atu he kūmara iti-matotoru kei roto te whakakorikori DMDEE ki roto i te kapiti, i te āputa rānei e turuturu ana.
2. Tauhohenga:Ka pā te kirikiri ki te wai. Mā te kaha whiriwhiri wai o DMDEE ka taea te whakahohe i tētahi tauhohenga kaha ki te wai tonu.
3. Whakawhanuitanga:Ka tīmata te whakawhanui o te kirikiri i roto i ngā hēkona. Ka taea e ia te whakanui ake i tōna rōrahi tae atu ki te 30 ngā wā, ka puta he pēhanga e pana ana i te pahuka ki roto i ia kapiti iti.
4. Te whakamaroke:Ka tere te whakamaroke o te pahuka hei totoka pakari, rite tonu ki te rapa. Mā tēnei ka whakapakeke te hiri, ā, ka mutu tonu te rere o te wai.

Ko tēnei tukanga tere he painga matua o ngā Whakakōkī Amine Polyurethane matatau. Mā tēnei ka taea e ngā tohunga hangarau te mahi ki te pēhanga wai hohe, he mea e kore e taea e ngā rauemi puhoi te whakapakeke.

Te Waihanga i tētahi Ārai Pahuka Pūtau-Katia, Pakari

Ko te kounga o te hiri ā-wai e whakawhirinaki ana ki te hanganga o te pahuka. He tino pai a DMDEE ki te whakaputa i te pahuka matotoru, he pūtau-kati. He hanganga tēnei o ngā mirumiru iti, takitahi kua tino hiritia tetahi i tetahi. Kāore e taea e te wai te uru, te whiti rānei i roto i tēnei ārai.

Ko te hua ehara i te mea he mono rangitahi noa iho engari he hiri pumau, he hiri kotahi. Ka noho te pahuka pūtau-katia hei wāhanga nui o te hanganga, ka whakarato i tētahi otinga ārai wai ngāwari, pakari hoki e mau ana mō ngā tekau tau.

He maha ngā āhuatanga matua o te pahuka i hangaia mā te whakamahi i te whakakorikori DMDEE:

He mea nui te tauhohenga whakahaeretia e te whakakorikori. Ka ārai i te hanganga o ngā pūtau nui, e hono tahi ana (tuwhera), ka taea ai e te wai te mimiti. Nā tēnei ka waiho ngā grouts whakakorikori DMDEE hei kōwhiringa pai rawa atu mō te hanga i tētahi arai ā-wai pumau, pono hoki.

Te Huarahi Pai Ake o te Grout Whakakorikori DMDEE i Ētahi Atu Tikanga

He mea nui te whiriwhiri i te tikanga ārai wai tika mō te angitu me te pumau o te whakatikatika. Ahakoa he maha ngā kōwhiringa, he pai ake te mahi a te grout polyurethane kua whakakorikoria e te DMDEE i ngā tikanga tuku iho pēnei i te werohanga epoxy me te sima waipēhi, inā koa ka pa ki ngā turuturu kaha me ngā kapiti hihiri.

vs. Werohanga Epoxy mō ngā turuturu kaha

He tikanga rongonui te werohanga epoxy mō te whakatika i te raima hanganga. Ka hangaia he hononga tino kaha, pakari hoki e whakahoki mai ana i te āhua o te hanganga pakaru. Heoi, ka heke tōna whai huatanga ina tūtaki ki te turuturu wai kaha. Me whai papa maroke, ma hoki ngā epoxy kia pai ai te whakamaroke me te whakatutuki i te hononga kaha.

Te Wero ki ngā Epoxies me te Wai 

He maha ngā raruraru o te rere o te wai kaha mō ngā kapia epoxy:

• Ka taea e te wai e rere ana i roto i te kapiti te whakararuraru i te tukanga whakamaroke o te epoxy, te horoi rānei i mua i tōna whakapakeketanga.
• Ko te nuinga o ngā epoxies me whakamahi i ngā mata maroke, nā te mea ka kore e taea te piri tika ki te raima nā te nui o te makuku.
• Me aukati tuatahi e ngā tohunga hangarau te turuturu mā te whakamahi i ngā mahi rangitahi i mua i te whakamātau ki te werohanga epoxy.

Koinei te wāhi i whakakorikoria ai te DMDEEte kūmara polyurethanetino pai. He mea hanga motuhake kia mahi i roto i ngā taiao mākū. Engari kāore e āraia e te wai, ka whakamahia te wai hei matū tauhohe. Ka rapu te kūmara i te makuku, ā, ka tauhohe ina pā, ka tere te horapa hei hanga i tētahi hiri ngāwari, ātete wai e aukati ana i te turuturu mai i roto ki waho.

Ko tētahi atu rerekētanga nui ko te ngāwari. Ka maroke te epoxy hei totoka mārō, pakari. Ka maroke te polyurethane grout hei pahuka pakari engari ngāwari. He mea nui tēnei mō ngā hanganga e pāngia ana e te whānui me te whakaheke wera, te taunga iti rānei.

Mō ngā turuturu kaha, he mārama te kōwhiringa. Ka whakaratohia e te kūmara polyurethane he otinga tere me te urutau e mahi ana ki te wai, kaua ki te ārai i te wai.

vs. Sima Waipēhi mō ngā Whakatikatika Pumau

He otinga tere noa te sima waipēhi hei aukati i ngā turuturu. He paura tēnei, ina konatunatua ki te wai, ka tere te whakapūmau hei hanga i tētahi puru mārō. Ahakoa ka taea e ia te aukati i te turuturu pēhanga iti i roto i ngā meneti, he wāhi poto noa iho, ehara i te whakatikatika tuturu. He ngoikore tōna mahi mō te wā roa nā ōna āhuatanga rauemi tūturu.

Ko te ngoikoretanga matua o te sima waipēhi ko tōna pakari me te ngoikore o te piri. Ka hangaia he puru mata pakarukaru e kore e piri pono ki te raima o nāianei.

E ai ki ngā kairangahau ko te momo rahunga matua o ngā mono sima ko te "whakakore hononga," arā, ka pakaru te hononga i waenga i te mono me te rauemi e karapoti ana i raro i te pēhanga, i te nekehanga rānei. Ka wehe noa te mono i te pakitara o te kapiti.

Ko te tikanga o tēnei ngoikoretanga, kua whakaritea kia kore e taea te whakatika. Mā te nekehanga ā-taiao o te hanganga raima—mai i ngā huringa pāmahana, i te taunga whenua rānei—ka pakaru, ka wetewete rānei te mono uaua, ā, ka hoki mai anō te turuturu. He maha ngā wā ka kore e taea te whakatika i roto i ngā wiki, i ngā marama rānei.

He rerekē, ko ngā grouts polyurethane e whakakahangia ana e te matatauNgā Whakakōkī Amine Polyurethanehe otinga pakari, he otinga roa. Ka werohia te wai para ki roto i te kapiti, ka whakakī i tōna hohonutanga katoa. Kātahi ka whānui hei hanga i tētahi hononga pakari ki te raima tonu.

Ka noho te pahuka pūtau-katia, ngāwari, hei wāhanga nui o te hanganga. Ka taea e ia te tu atu i ngā huringa mākū/maroke, te ātete i te waikura mai i ngā katote wai whenua, me te tu atu i ngā huringa tio-rewa me te kore e pirau. Mā tēnei ka mau tonu te whai huatanga o te whakatikatika mō te roanga o te hanganga, ka aukati i te huringa o ngā whakatikatika rangitahi, ā, ka whakarato i te rangimarie pono o te hinengaro.

Ngā Whakamahinga Whaihua me ngā Mahi Pai rawa atu

He maha ngā otinga whai hua, whai mana hoki mō ngā momo wero ārai wai o ngā grout polyurethane kua whakakorikoria e te DMDEE. Mā te mārama ki ā rātou whakamahinga pai me te whiriwhiri i te pūnaha tika ka angitu, ka pumau hoki te whakatikatika. He mea nui anō hoki te whai i ngā tikanga pai mō te whakahaere mō te haumaru me te mahi.

Ngā Whakamahinga Pai mō te Āraiwai

Ko te whai huatanga o te kūmara polyurethane e whakawhirinaki ana ki te whakataurite i te momo hua ki ngā āhuatanga turuturu motuhake. Ko te nuinga o ngā tohunga e whiriwhiri ana i waenga i ngā momo kūmara e rua: he wai-aroha me te wai-aroha.

Ngā Grout Wai-aroha:He tino pai ēnei momo "wai-aroha" mō te hiri i ngā kapiti i roto i ngā taiao makuku tonu pērā i ngā rūma o raro, ngā pakitara pupuri, me ngā kauhanga e turuturu tonu ana. Ka mimiti i te wai, ka hanga he kirikiri, he pahuka rānei e ngāwari ana, e whakaora ana i a ia anō. Nā tēnei ka tino pai mō te hiri i ngā kapiti kore-hanganga e pāngia ana e te nekehanga iti, te wiri rānei.

Ngā Grouts Wai-whakaarokore:Ko ēnei pūwero "ārai wai" te otinga matua mō te aukati i ngā turuturu kaha, pēhanga teitei. Ka tauhohe rātou ki tētahi whakakorikori hei hanga i tētahi pahuka pūmau, katia-pūtau e pana kaha ana i te wai ki waho. Nā tēnei ka nui ai ēnei mō te whakapuru ārai i muri i ngā hanganga, te whakakī i ngā āputa nui, me te aukati i ngā turuturu e pupuhi ana i roto i ngā tāke, i ngā awaawa rānei.

Te Haumaru Tuatahi: He Mahi Pai Rawa 

Me whakatairanga tonu ngā tohunga hangarau i te haumaru i te wā e mahi ana me ēnei rauemi. Ko te whakahaere tika ko te mau i ngā mōhiti ārai-pipi me ngā karapu ātete-matū. He mea nui te mahi i roto i tētahi wāhi e pai ana te hau kia iti ai te kukū o te kohu. Ko te whai i ēnei tikanga ka ārai i te whara, ā, ka whakarite kiataiao tono haumaru.

Te Kōwhiri i tētahi Pūnaha Whakapūmau Mahi-Tiketike

Ko te whiriwhiri i tētahi pūnaha whakapūkara pai rawa atu me titiro ki tua atu i te momo hua taketake. Ka arotakehia e ngā tohunga ētahi āhuatanga matua hei whakapūmau i te mahi roa me te pono. Me tutuki i tētahi pūnaha kounga teitei ngā whakaritenga hangarau, ngā tiwhikete, me te tautoko a te kaihanga.

I te wā e whiriwhiri ana i tētahi pūnaha, tirohia ēnei tohu kounga:

• Mahi kua Manatokohia:Me whakarārangihia e te pepa raraunga hangarau (TDS) o te hua ngā āhuatanga matua pērā i te matotoru, te kaha kume, me te kaha piri ki te raima mākū (ko te mea pai ko >200 psi).
• Ngā Tiwhikete Ahumahi:He maha ngā hua rongonui e mau ana i ngā tiwhikete pēnei i te NSF/ANSI 61 mō te whakamahi i roto i ngā tāke wai inu, e tutuki ana rānei i ngā paerewa ASTM mō te whakatika raima.
• Te Mana Motuhake o te Kaihanga:Mahi tahi me ngā kaihanga kua whai tiwhikete ISO 9001. Me whakarato rātou i te tautoko hangarau pakari, tae atu ki ngā aratohu tono taipitopito me te urunga atu ki te āwhina hangarau.

Ko te whāinga matua ko te whiriwhiri i tētahi pūnaha e kore e aukati noa i te turuturu i tēnei rā tonu, engari e whakarato ana hoki i tētahi arai pakari, ngāwari, ā, pumau hoki mō te roanga o te oranga o te hanganga.

Hei aukati i ngā turuturu wai tonu, ko te kūmara polyurethane kua whakakorikoria e DMDEE te otinga tino pai, tino whai hua. Nā tōna kaha ki te whakakorikori i te tauhohenga tere ki te wai ka whakarite kia hangaia he ārai pakari, ngāwari, ā, kāore e taea e ētahi atu tikanga te rite. He nui hoki ngā painga taiao o tēnei huarahi.

Mā te whiriwhiri i tētahi tikanga whakatika roa pēnei ka whakatairanga i te pumau mā te:

• Te whakaroa i te roa o te ora o ngā hanganga o nāianei.
• Te whakamahi i ngā rauemi kore-haumanu e pā kino ana ki te oneone, ki te wai whenua rānei.
• Te whakaiti i ngā para mai i te whakahoro me te whakakapinga i ngā wā katoa.

Kati te whakahaere i ngā turuturu, ā, whakakorea rawatia. Kōwhiria he kirikiri ārai wai e whakamahi ana i te mana o te whakakorikori DMDEE hei whakatika tere, pumau hoki.
