Mahinga Me te Whakamahinga
TPEG
1. Ko tenei hua kaore i te paitini, kaore i te riri, he pai te wairewa wai, he wairewa i roto i te wai me nga momo whakarewa pararopi, a he mea tino nui mo te reanga hou o nga miihini kapia kaha.
2. He whaiti te tohatoha o te taumaha ngota o tenei hua, he iti te ihirangi o te polyethylene glycol, he tiketike te reeti pupuri o nga here rua, a ka tino pai ake te mahi polymerization.He tiketike te tere o te huringa o te hua.He pai te mahi matawhānui a te kaihoko.3. Ko te kaihoko whakaheke wai i whakahiatohia e tenei hua he kaha te marara matūriki me te kaha pupuri, a he pai te painga o te marara ki runga i te maha o nga mea paura penei i te ciment.He nui te reiti whakaheke wai me te iti o te whakamahi sima.Ko te kounga o te ciment te taapiri ko te 0.2% -0.5% Te whakaheke wai raima, ka taea e te reiti whakaheke te wai neke atu i te 30%.
4. I muri i te taapiri i te kaihoko whakaheke wai ki te raima, ka hangaia he kiriata adsorption ki runga i te mata o nga matūriki ciment, e whakaheke ana i te tere o te whakamakuku o te ciment, ka tino pai ake te tipu o te kiripiri kohatu ciment, ka whakaiti i nga waahi kapi o te wai. te whakaetonga, me te hanganga whatunga he nui ake te kiko, ka taea te whakapai ake i te raima Ko te kaha ake i te 20%.Ka taea te whakamahi ki te raima hokohoko teitei (i runga ake i te C60).
5. Ko te kaihoko whakaheke wai i hangaia e tenei hua ka taea te whakapai ake i te rheology me te kirihou o te raima.Ka taea e ia te whakatutuki i te hanganga raima ma te rere-whaiaro, te pupuhi, me te kore wiri, ka taea te whakanui ake i te tere o te hanga me te whakaiti i te utu hanga.
6. Ko tenei hua he hua matomato me te taiao, te ihirangi katote chloride: ≤0.1%.Kia mau ki nga paerewa whakahaere tiaki taiao o te ao ISO14001.
HPEG
1. He pai te wairewa o tenei hua.
2. Ka whakamahia e tenei hua he whakakorikori tino kaha me te tukanga whakahiato motuhake.He whaiti te tohatoha o te taumaha ngota, he iti te ihirangi ethylene glycol, he nui te reeti pupuri here rua.Ko te mahi polymerization kua tino pai ake, he nui te tere o te huringa hua, ko te hua whakaheke wai waikawa polycarboxylic i whakahiatohia e te hua he mea tino whai hua, he pai te mahi matawhānui o te whakaheke wai.
3. Mahinga me te tohu kounga o te whakaheke wai waihanga:
1) Mahi utu nui.I roto i te take o te whakatutuki i te reiti whakaheke wai, he utu nui te mahi.
2) He iti te whakaurunga me te tere whakaheke wai.Ko te waipiro whaea-whakaiti wai me te ihirangi totoka o te 20% me te reiti whakaheke wai o te 1.0% (te nui o nga rauemi cimenting) ka tae ki te 30-35%.
3) He pai te pupuri kirihou.He iti te ngaronga o te raima i muri i te 1h.
4) Tino pai te mauroa.Ka taea te whakaiti nui i te kohi wai me te whakapai ake i te mauroa o te raima.
5) Te tiaki matomato me te taiao.I roto i te tukanga whakaputa o te whakaheke wai, kaore he formaldehyde me te katote chloride e kino ana ki te taiao e whakamahia ana, he iti te ihirangi o te sulfate.
Ētahi atu korero
