I-PVA Fiber Yokwenziwa Kokhonkolo Osebenza Kakhulu

Iqinile, Ukulawula Ukuphuka Okuthembekile kwe-UHPC nangaphezulu

I-PVA fiber yokwenziwa iyinhlanganisela esebenza kahle kakhulu eyenziwe nge-polyvinyl alcohol. Yenzelwe ngokukhethekile ukuqinisa ukhonkolo nokunciphisa ukuqhekeka. Le fibre isebenza kahle kukhonkolo esebenza kakhulu (I-UHPC), i-shotcrete, izingxenye ze-precast, kanye nezinye izicelo ezidingekayo.

Imicu mikhulu, ukusabalala ngokufanayo, futhi ubophe ngokuphephile nge-matrix kasimende. Lesi sibopho esiqinile sisiza ukulawula ukuqhekeka kokuncipha okuvame ukuvela phakathi nokwelashwa. Ngaphezu kwalokho kuqinisa ukumelana nomphumela kanye nokuqina. Ngokungafani nemicu yensimbi, Imicu ye-PVA ayigqwali. Zihlala zizinzile ngesikhathi futhi zigcina ukhonkolo ubukeka uhlanzekile futhi bushelelezi.

I-fiber ngayinye inobude nobubanzi obungashintshi. Leli fomu lomfaniswano liqinisekisa ngisho nokusatshalaliswa uma lixutshwa kukhonkolo. Umphumela uba ukusebenza kangcono kanye nama-clumps amancane. Abahlinzeki besevisi bakuthola kulula kakhulu ukubeka futhi bagcine bephezulu ngaphandle kokuthatha isinyathelo esengeziwe.

I-PVA fiber kwandisa amandla e-flexural kanye nokumuncwa kwamandla. Izinhlaka ziba namandla kakhulu ngaphansi kokukhathazeka, ukudlidliza, noma imithwalo engalindelekile. Lokhu kuyenza ifaneleke phansi, amabhuloho, imigudu, nama-slabs ezimboni lapho ukusebenza kahle okuhlala isikhathi eside kubalulekile.

Into yenelisa imibandela yomhlaba wonke yamafayibha okwenziwa kukhonkolo. Ihambisana neningi lezinhlobo zikakhonkolo nezixube ezivamile njengama-superplasticizer. Awekho amathuluzi ahlukile adingekayo– mane nje uyifake phakathi nokuhlanganisa okuvamile.

Ngoba ayigqwali futhi imelana ne-alkali, I-PVA fiber igcina izindawo zayo zokuhlala ezindaweni ezimbi. Igcina ukwakhiwa okusimeme ngokwandisa ubude besikhathi sokuphila kanye nokunciphisa izidingo zokunakekela.

Sebenzisa le fibre ukwakha ephephe kakhulu, izakhiwo zikakhonkolo ezihlala isikhathi eside ezinokuqhekeka okumbalwa okuphawulekayo nokulungiswa okuncane ngesikhathi.

Izicelo ze-Synthetic Fibers Plastic Synthetic PVA Fiber Reinforced Concrete Admixture Anti Crack Fiber ye-UHPC

Khulisa Ukusebenza Okuqinile Nge-PVA Synthetic Fibers

Inamandla kakhulu, Kakhudlwana, Ukhonkolo Ongazweli Ukuqhekeka

I-PVA (polyvinyl utshwala) imicu yokwenziwa inketho ehlakaniphile yezingxube zesimanje zekhonkrithi. Le micu emincane ihlangana ngokulinganayo kukhonkolo. Basiza ukubamba indaba omunye komunye lapho ukucindezeleka nokukhathazeka noma ukunyakaza kwenzeka. Lokhu kunciphisa kakhulu ukuhlukana kusuka ekuncipheni, izinga lokushisa liyashintsha, noma umthelela.

Osonkontileka basebenzisa imicu ye-PVA kukhonkolo esebenza kakhulu (I-UHPC) nezinye izingxube eziyinkimbinkimbi. Imicu ilingisa ukuqiniswa kwangaphakathi. Baxhuma ama-micro-cracks ngaphambi kokuthi abe yizinkinga ezinkulu. Lokhu kusho impilo ende yezinhlaka ezifana namabhuloho, amavesi, phansi, kanye nama-elementi e-precast.

Ngokungafani nemicu yensimbi, Imicu ye-PVA ayigqwali. Bahlala beqinile ngaphakathi kukakhonkolo iminyaka. Ngaphezu kwalokho azihlanganisi phakathi nokuxuba. Lokhu kunikeza ubushelelezi, isethi njalo isikhathi ngasinye. Ochwepheshe bawathola kulula ukusebenza nawo– awekho amadivayisi ahlukile noma izenzo ezidingekayo.

Amafayibha athuthukisa ukuqina kwe-flexural nokuqina. Ukhonkolo nge-PVA ungashintsha kancane ngaphandle kokulimaza. Imunca amandla amaningi ngesikhathi sokudla okungalindelekile. Lokho kuyenza ivikeleke kakhulu ezindaweni zokuzamazama noma ezindaweni ezinabantu abaningi.

I-PVA fiber admixtures yanelisa izimfuneko eziqinile zomkhakha. Bahlolelwa ukuqina, ukuqina kwesibopho, kanye nokuhambisana nosimende. Ungawangeza ngqo esitshalweni sokuhlanganisa noma esizeni. Amazinga omthamo aphansi– ngokuvamile kalula 0.5% ku 2% ngenani likakhonkolo.

Le sevisi yehlisa izindleko zokulungisa futhi yandisa ubude besikhathi sokuphila. Iphinde isekele izigaba ezincanyana kanye nemiklamo elula. Abaklami bezakhiwo nabaklami bakhetha imicu ye-PVA lapho ukusebenza kahle kubaluleke kakhulu.

Izinzuzo ezibalulekile: .
– Iyeka ukukhula kwezingane kanye nesikhathi eside.
– Yandisa umthelela kanye nokumelana nokukhathala.
– Isebenza kahle ku-UHPC, i-shotcrete, kanye nokhonkolo ozihlanganisayo.
– Ayinazi futhi imelana ne-alkali.
– Kulula ukulinganisa nokuxuba.

Sebenzisa imicu yokwenziwa ye-PVA ukuze uthuthuke ngobuchule, kunamandla, kanye nezakhiwo zikakhonkolo ezethembekile ezengeziwe.
