Nga Whakapiri Raima Maamaa | Nga Kaipupuhi Hukarere Mahinga Nui mo te Raima Pukoro
raima pahuka Ko te kaihoko pahuka i tino pahuka i nga tikanga miihini na roto i te punaha pahuka o te miihini pahuka, ka konatunatua te pahuka ki te slurry sima. Na roto i te miihini whakapoka i te punaha miihini mo te hanga-a-waahi, te hanga pokepokea ranei., na roto i te tiaki taiao i hangaia e te maha o nga pores kati o te momo hou o nga rauemi whakamatao marama., He maha nga rangahau me te whakawhanaketanga o nga tohunga o roto me nga iwi ke, e whakamahia nuitia ana i roto i nga papanga pakitara.Painga: kiato iti, taimaha mama, whakawera waiariki, whakamau oro, mahi rū.
1 pahuka Te hanga pahuka i te nuinga e mohiotia ana ko “pahuka”, ko te whakatakotoranga “pahuka”, ko te taputapu matua ko te miihini pahuka.
1.1 Te hanga pahuka i te mahi.Ko te mahi whakapokapoka ko te taapiri i te wai ki te waimeha i te wairewa teitei o te kaihoko pahuka 20 ki 30 wā, ka waiho hei waimeha mokamoka, katahi ka pana ki roto i te miihini pahuka, na roto i te mahi a te hau pehanga teitei, hanga pahuka i.
1.2 Mana kounga pahuka.I muri i te momo me te kounga o te kaihoko pahuka i whakatauhia e te whakamatautau, Ko te mana o te kounga o te pahuka kaore e tika kia whakatauhia e te whakamatautau o te raima pahuka, ma te whakatau o te mita pahuka i te mara ka taea te whakahaere i tona kounga.Ko nga taonga whakahaere kounga ko te nuinga o te pumau me te makuku..
(1) Te tawhiti o te whakataunga: ko te nuinga e tohu ana i te pumau o te pahuka. I muri i te pakaru o te mirumiru, ka heke te rahi o te pahuka me te whakatau.Ma te ine i tona tawhiti noho, ka taea te mohio ki tona pumautanga.Ko te tawhiti o te whakataunga pahuka i te pakitara kaua e neke ake i te 90mm i roto i te 1h.
(2) Te whakaheke toto: ko te nuinga e tohu ana i te makuku o te pahuka, ka nui ake te toto.Ka nui ake te wai, te kino te kounga o te pahuka, ko te tikanga ka heke te maha o nga mirumiru i roto i te pahuka i te wa e piki haere ana te wai, ka arahi ki te porosity o te raima pahuka i heke, me te whakanui ake i te kapi, pahuka i te mimi wai me te kawe werawera i piki ake, e pa ana ki tona whakamahinga, te pakitara whakaata ringihia, e hiahia ana ki te iti iho i te 1h te whakaheke toto 90%.
(3) Mirumiru diameter: te diameter mirumiru i roto i te pahuka i hanga pakitara ko te nuinga 1~2mm, he maha iti o 2~3mm me 0.5~1mm, nui rawa te diameter mirumiru (nui ake i te 3mm) kaore i te whai tohu, mehemea 60% o te diameter mirumiru he iti iho i te 0.5mm, ka kiia hoki kaore he tohu.
1.3 Nga mea whakahaere o te pahuka i te kounga
Te hanga pahuka i te kounga teitei, ehara i te mea ko te kaihoko pahuka noa hei whakatau, mihini pahuka, wai waimeha, te pāmahana o te taiao me era atu mea he paanga.Na reira, ki te whiwhi pahuka i te kounga teitei me whai i nga waahanga e whai ake nei o te matawhānui, mana kounga matawhānui.
(1) Te whakahaere i te kaihoko pahuka.Ka whai awe te kaihoko pahuka i te tawhiti o te whakataunga, tere toto me te diameter mirumiru, engari he nui te awe ki runga i te tawhiti o te whakataunga.Ko te kaihoko hukahuka o te kounga teitei he mea hanga ki te pahuka, i roto i te take o te whakarite nui pahuka i maha, he iti hoki te tere o te toto.I tua atu, rerekē te kaihoko pahuka ahakoa te whakamahi i taua miihini whakapokapoka he rereke ano te diameter o te mirumiru, te pokey teitei o te kaihoko pahuka i hangaia e te finer.Foaming agent na te momo o te surfactant, he rereke ano te diameter o te pahuka, he tino mātotoru etahi o te pahuka i hangaia, ko etahi kaore i te pai.
No reira, he mea tino nui te kowhiringa o te kaihoko pahuka pai.I naianei, he maha nga momo kaihoko pahuka i runga i te maakete, me whakawa tona kaiwhakaari kino i roto i nga momo kitenga, kaua hoki e ngakaukore ma te pukapuka ako.
(2) Te whakahaere i te miihini pupuhi.Ko te miihini pahuka ka nui te awe ki te tere toto, mirumiru diameter me te pahuka maha, a he iti te awe ki runga i te tawhiti o te whakataunga.Karekau nga wa pahuka i te kounga o te pahuka, engari ko te kounga o te kaihoko pahuka, e kore e te kōrero i konei. Foaming mīhini hau compressor pēhanga he uara wā tino pai, he nui rawa te pehanga, he kikokore rawa te pakitara mirumiru, he nui ake te tawhiti o te whakataunga.A he iti rawa te pehanga, e kore e taea te whakaputa pahuka, he paheketanga whakangao miihini pahuka ranei. He rereke nga awhe pehanga tino pai o nga miihini pupuhi rereke.
(3) Te whakahaere wai.He rereke te kaha o te pakeke o te wai ki te pumau o te pahuka..
He rereke te kounga o te pahuka ki te maimoatanga o mua o te wai.Ko etahi maimoatanga o mua, ka whakapai ake i te pumau o te pahuka, whakaitihia te tere o te toto.Ko etahi o mua ka nui ake te nui o te pahuka me te maha o te pahuka, engari kaore i te pai ki te pumau o te pahuka.
(4) Te whakahaere i te pāmahana.Ka rereke te paanga o te pāmahana rereke ki te kounga o te pahuka, ka whakanui ake te pāmahana teitei i te putanga o te pahuka, engari ka angiangi ake te pakitara pahuka, karekau e pai te pumau o te pahuka.Pahana iti, ehara i te mea ngawari te pahuka, kua piki ake te makuku o te pahuka, engari he pai ake te pumau.I roto i te miihini pahuka i te raumati kaua e waiho i roto i te mahi ra wera, kia rite ki te karo i te nui o te pāmahana me te pa ki te kounga o te pahuka i te takurua, kia i roto i te tikanga whakawera o te pahuka i, te whakamahi ranei i te wai wera ki te waimeha i te kaihoko pahuka, kia pai ake ai te hua o te pahuka.
2. Hangaia he slurry raima pahuka i
Ka whakaranuhia e tenei mahi te pahuka me te parapara sima kia hanga he parapara raima kua pahuka i te mutunga ka taea te riringi ki roto i te kohao pakitara..
(1) Te mahi ranu.E rua nga momo mahi ranu: te ranu puranga me te whakaranu tonu.I tenei wa, ia hinonga ko USES te mirumiru whakaranu tonu, ahakoa ko te mirumiru whakaranu mokowhiti te tono, engari he torutoru.I te timatanga o te whanaketanga o te raima pahuka, Ko te ranu puranga he mahinga whanui. Ko te tukanga ko te whakaputa i te pahuka me te slurry ciment i te tuatahi, katahi ka taapirihia nga mea e rua ki roto i te miihini whakaranu pahuka i te momo vane ka uru ki roto ki te slurry raima pahuka. He pai ake tenei tikanga mo te hanga hua., mo te maka ki roto i te waahi na te iti o te kaha, kaore e pai mo te mahi i runga i te waahi.
(2) Ko te whakaranu haere tonu ko te tuku i te pahuka me te slurry sima ki roto i te whakaranu pateko i te wa ano, me te hanga i te slurry sima pahuka i roto i te ranu pateko kahore power.Ko te whakaranu pateko te nuinga mohiotia rite te pahuka i ranu puoto. It is a high-pressure steel cylinder with a diameter of 1000mm ~2000mm. A static mixing piece is installed in the middle.
(3) Quality control of mixed foam.The quality of foam is mainly reflected in two aspects: uniformity of foam cement slurry, namely uniformity, and density control of foam cement slurry.The slurry should have a high degree of uniformity, and its appearance is bright and smooth, with elastic hand pressure, no foam floating, and no visual phenomenon of uneven mixing.
The slurry density shall meet the design requirements, and the difference in wet density shall not be more than 5%, without fluctuation and instability.At present, a prominent problem of cast-in-place is the density fluctuation, which causes the quality instability.And the reason for that is that when you mix it up, ka piki, ka heke te nui o te pahuka, me pehea te whakahaere i te kiato he take nui.
(4) Ko nga mea matua e whakahaere ana i te arotautanga o te slurry sima pahuka:
a. Taurite mana tauwehe.Ko nga mea whakahaere o te whakakao riterite o te pahuka sima slurry ko te nuinga ahakoa he whaitake nga tawhā hoahoa o te whakaranu pateko, ina koa ko tona roa, te tau, Ko te koki me te tikanga whakarite o nga waahanga whakaranu o roto. Ko enei tawhā he tino pai te whakataetae. Mena kaore i te tika te whakataetae, ka kore noa te slurry.He rereke nga hoahoa o nga kaihanga rereke, ko te kaupapa matua ko te kaha ki te whakatutuki i te whaitake, ahakoa te hoahoa i mua i te arotautanga whakamatautau.
b. Ko nga take whakahaere kiato.Ko te take whakahaere o te kiato slurry sima pahuka ko te ōwehenga o te pahuka ki te slurry sima ka uru ki te whakaranu pateko, ara, ahakoa he tika me te tika te ōwehenga o te pahuka ki te slurry sima.Ka nui ake te ōwehenga, te mama ake te slurry.Ki te kore e tika te whakahaere i te ōwehenga o te rua, ka rere ke te kiato.Ko te take matua ko te whakaurunga o nga taputapu ki te whakaurunga o te pahuka me te slurry mana whakahaere., me te tohu o te aunoatanga o tenei tikanga.I tenei wa, ko etahi taputapu kaore i whakauruhia ki runga i te miihini whakahaere, ehara i te mea ngawari ki te whakahaere kiato.
Ko Cie-China.org te kaiwhakarato taapiri raima pahuka e whakarato ana i te kaihoko hukapapa raima, superplasticizer,whakakaha kaha raima pahuka mo te raima mama, Nga poraka CLC. Mena kei te rapu koe pahuka agent, tēnā koa koa whakapā mai.
