Tikanga mo te Whakaritea Polycarboxylate Superplasticizer Kua Whakakotahitia I te Pawera Rūma:
Ko te hangahanga e pa ana ki te waahi hangarau o nga whakaurunga rauemi hanga, ina koa e pa ana ki te polycarboxylate superplasticizer kua whakahiatohia i te pāmahana rūma me te tikanga whakarite.Kei roto i te tikanga whakareri ko nga waahanga e whai ake nei: te taapiri i te polyether methyl allyl polyoxyethylene ether, te hauwai peroxide me te waikawa tetradecyl sulfonic 2-acrylamide ki roto i te wai whakaheke hei whakarite i te otinga turanga;te whakamakuku i tetahi otinga A kei roto i te waikawa kiriaku, te waikawa methacrylic me te kaihoko whakawhiti mekameka waikawa mercaptoacetic me te wairewa wai o te huaora C, te whakaoho rite, te kawe i te tauhohenga polymerization tuwhena kore utu i te pāmahana rūma, me te whakarite i te uara pH o te punaha tauhohenga. kia 6-7 ma te whakamahi i te houra wai i muri i te mutunga o te tauhohenga, na reira ka whiwhi te polycarboxylate superplasticizer.Ko te superplasticizer polycarboxylate whiwhi e te tenenga e taea te pupuri marara roa-tonu, he mekameka manga roa, he pai i roto i te pūmautanga marara, ohie i roto i te tukanga faaineineraa, me te iti i roto i te kohi pūngao, ka taea te synthesized i te pāmahana rūma me he painga ōhanga pai.
Mahinga Motara:
1. He homologous i waenga i te reiti whakaheke wai o te motar me te rerenga o te whakapiri ciment.Ka nui ake te rere o te whakapiri ciment, ka nui ake te tere o te whakaheke wai o te motar.
2. Ka piki te tere me te teitei o te tere whakaheke wai ka piki ake te inenga.Ina he rite te inenga, ko te reiti whakaheke wai o te paura PCE he 35% teitei ake i tera o etahi atu superplasticizer i te maakete.
3. Na te awe o te whakaurunga me te kirikiri whakahiato, he rereke te tere o te whakaheke wai i roto i te raima mai i te mota.I te wa e pai ana te whakaurunga me te kirikiri kirikiri ki te rere raima, ka nui ake te reiti whakaheke wai o te raima i to te mota.
4. He mahi whakatio ina kei runga ake te pāmahana -5ºC.Na ka taea te whakamahi i roto i te raima antifreezing.
Ko te Polycarboxylate Superplasticizer Āhuatanga Hua:
1. He nui te whakaheke o te wai: ka taea e ia te whakaheke i te wai ki te neke atu i te 25%, me te whakapai ake i te wai.
i raro i te ahua o te nui o te wai i tapiritia ki te raima;
2. te kaha o te paheketanga: i roto i te whakamaroke rehu, ka nui ake, iti iho ranei te kino o te roopu carboxylic.
polycarboxylate superplasticizer tuku iho.Na ka tino whakaitihia te mahi pupuri i muri i te wai
ransformed to totoka.Ko te Sp-409 he mea hanga e tetahi tukanga motuhake, kia kore ai e pakaru te roopu waikawa carboxylic.
i roto i te mahi hanga paura, kia mau tonu ai te mau tonu o te waipiro whaea wai taketake.
3. He pai te whakarewatanga me te tere o te whakakorenga tere: na ona matūriki rite me te nui o te waahanga mata motuhake.No reira, ka taea
kia tere te rewa i roto i te tukanga o te whakakore i te wai.A kaore he poke e kitea ana i muri i te whakakorenga.
Te whānuitanga o te tono:
1. He pai mo nga kaupapa hanga-tawhiti momo raima raima.
2. He pai mo te whakakotahi i te raima noa, te raima mahi teitei, te raima kaha me te raima kaha ultra-tiketike.
3. He pai mo te raima karekau, parepare me te raima mauroa teitei.
4. E tika ana mo te raima mahi teitei me te raima rere teitei, te raima whakataurite whaiaro, te raima ataahua me te SCC(whaiaro raima raima).
5. He pai mo te inenga teitei o te raima momo paura kohuke.
6. He pai mo te raima papatipu e whakamahia ana i roto i te huarahi tereina, te reriwe, te piriti, te kauhanga, nga kaupapa tiaki wai, nga tauranga, te wapu, te whenua me etahi atu.
Haumaru me te aro:
1. Ko tenei hua he toka toka kaore he paitini, he pirau me te parahanga.
Kare e taea te kai ina tae mai ki te tinana me te kanohi, tena koa horoi ki te wai ma.Ina he mate mate mate tetahi tinana, me tere te tuku i te tangata ki te hohipera kia ora ai.
2. Kei te rongoa tenei hua i roto i te putea pepa me te putea PE o roto.A ape i te ua me nga tini mea hei whakauru.
3. Ko te wa taurangi kounga ko te 12 marama.
