Ngokumelana nomthelela omkhulu, sinikeza Steel Fibers, ukumiselela okuhle kwe-wire mesh eshiselwe ezitezi zezimboni nezinto ezisakazwa ngaphambilini. Siphinde futhi sihlinzeke ngama-Structural Synthetic Fibers akhethekile anikeza amandla aqinile wokushuba kwezicelo ezifunayo. Le micu ihlakazeka ngokulinganayo kuyo yonke ingxube kakhonkolo, ukudala inethiwekhi yokuqinisa enezici eziningi ezingenakufinyelelwa nezindlela zendabuko. Le ndlela edidiyelwe yenza ukwakhiwa kube lula, isheshisa ukubekwa, futhi ithuthukisa ubuqotho buphelele kanye nokuhlala isikhathi eside kokhonkolo, ukunikeza impendulo yesimanje ezinseleleni zakudala zokuqhekeka nokuqina.

Izici ze-Pva polyvinyl alcohol high-high-high modulus fiber 3-18mm vinylon usimende ukhonkolo

1. I-Superior Crack Control kanye Nokuqina Okuthuthukisiwe:

Isici esiyinhloko semicu yethu yikhono layo lokuhlanganisa kokubili imifantu emincane eyakha ngesikhathi sepulasitiki kanye nemifantu emikhulu kakhonkolo oqinile.. Lokhu kuhlakazeka kwezinhlangothi ezintathu kudala i-matrix ehlangene kakhudlwana emelana nokusakazeka kokuqhekeka. Inzuzo eqondile ukuncishiswa okuphawulekayo kokubili kokuqhekeka kwe-plastic shrinkage kanye nobubanzi bokuqhekeka besikhathi eside. Lokhu kuholela ekukhoneni okuhlala isikhathi eside kakhulu okune-permeability ephansi, okuyinto ethuthukisa ukumelana nokungena kwamanzi, qhwa-ncibilika umonakalo, kanye nokugqwala kwanoma iyiphi insimbi egxilile. Umphumela uba isakhiwo esinempilo ende yesevisi kanye nezindleko zokunakekela ezincishisiwe.

2. Ukwanda Komthelela kanye Nokumelana Nokuhushulwa:

Imicu, ikakhulukazi insimbi kanye ne-robust synthetic macro fibers, kuthuthukisa kakhulu ukuqina kokhonkolo kanye nokusebenza ngemuva kokuqhekeka. Zimunca futhi zisabalalise amandla lapho zithinteka noma zilayishwa. Lesi sici sihlinzeka ngenzuzo yendawo ekwazi ukuqina futhi ejwayeleke kakhulu e-spalling, ukuqopha, kanye nokuhuzuka ngaphansi kwesiminyaminya sezimoto noma ukugqokwa kwemishini. Lokhu kuyinzuzo ebalulekile ezitezi zezimboni, izindawo zokugcina izimpahla, kanye namaphrojekthi engqalasizinda, okuholela endaweni egqoke kanzima egcina ubuqotho bayo ngokuhamba kwesikhathi.

3. Ukusebenza Kahle Kokwakha kanye Nokonga Izindleko:

Isici esibalulekile sokusebenzisa i-fiber reinforcement ukuqedwa kwe-weld wire mesh (WWF) ezinhlelweni eziningi. Lokhu kunikeza izinzuzo ezinkulu esizeni: yenza kube lula ukubeka, njengoba kungekho mesh okufanele isethwe noma okungenzeka kususwe indawo, futhi isheshisa yonke inqubo yokwakha. Ngokususa isinyathelo esidinga abasebenzi, amaphrojekthi abona izindleko zabasebenzi ezincishisiwe kanye nezikhathi zephrojekthi ezisheshayo. Ukusatshalaliswa okufanayo kwamafayibha nakho kuqinisekisa ukuqiniswa okungaguquki kuyo yonke ingxenye yekhonkrithi, ngokungafani ne-mesh, ezingabekwa ngendlela engafanele, okuholela ekusebenzeni okuthembekile nokubikezelwayo.

Ukucaciswa kwe-Pva polyvinyl alcohol high-high-high modulus fiber 3-18mm vinylon usimende ikhonkolo

I-High-Strength PVA Fiber Yokuqiniswa Kokhonkolo

Uhlolojikelele Lomkhiqizo

Lo mkhiqizo ungamandla aphezulu, high-modulus polyvinyl utshwala (I-PVA) i-fiber eklanyelwe ngokukhethekile ukusetshenziswa kusimende nokhonkolo. Imicu iza ngobude obusukela ku 3 mm kwe 18 mm. Zenzelwe ukuthuthukisa ukusebenza kukakhonkolo ngokuthuthukisa ukuqina kwayo, ukumelana nokuqhekeka, kanye nokuqina.

Izici Eziyinhloko

Amafayibha e-PVA anamandla amahle kakhulu okuqina kanye ne-elastic modulus ephezulu. Lokhu kusho ukuthi bangakwazi ukuthwala imithwalo esindayo ngaphandle kokuzelula kakhulu. Ubuso babo buphathwa ukuze buhlanganiswe kahle ne-cement paste, esiza ukudlulisa ingcindezi ngokulinganayo kuyo yonke imiksi. Imicu ihlakazeka kalula kukhonkolo ngaphandle kokugoqa, ukuqinisekisa ukusatshalaliswa okufanayo. Bamelana nokuhlaselwa kwe-alkali kusuka kusimende, ngakho bahlala beqinile ngokuhamba kwesikhathi. Ngokungafani neminye imicu yokwenziwa, Imicu ye-PVA ayiwohloki ngaphansi kwezimo ezivamile zokuphulukisa ukhonkolo.

Izinzuzo Ezinhlelweni Zokhonkolo

Ukwengeza le micu kukhonkolo kunciphisa imifantu enciphayo yepulasitiki. Baphinde balawule ububanzi bokuqhekeka kukhonkolo oqinile, okuthuthukisa ukuqina kwesikhathi eside. Izakhiwo ezenziwe ngokhonkolo oqiniswe ngefayibha ye-PVA zibonisa ukumelana nomthelela ongcono nokusebenza okuguquguqukayo. Lokhu kubenza balungele izitezi zezimboni, i-tunnel linings, izakhi ze-precast, kanye nokulungisa izinsimbi. Amafayibha athatha indawo noma anciphisa isidingo sensimbi enezikhala ezinhlelweni eziningi, ukonga abasebenzi kanye nokunciphisa izindleko. Ukuxuba kulula—faka nje imicu ngesikhathi sokuxutshwa njenganoma iyiphi enye ingxube.

Applications of Pva polyvinyl alcohol high-strength high modulus fiber 3-18mm vinylon cement concrete

Applications of PVA Polyvinyl Alcohol High-Strength High-Modulus Fiber (3–18 mm) in Vinylon Cement Concrete

Enhanced Crack Control

PVA fibers are added to cement concrete to reduce cracking. These short fibers (3–18 mm long) spread evenly through the mix. Babamba ukwaziswa ndawonye lapho ukucindezeleka kukhula. Lokhu kuvimbela imifantu emincane ukuthi ikhule ibe mikhulu. Umphumela uba nzima, indawo ehlala isikhathi eside.

Improved Impact and Abrasion Resistance

Concrete with PVA high-modulus fibers handles heavy use better. It resists chipping, scratching, and wear from foot or vehicle traffic. Iphansi, indlela yokuhamba ngezinyawo, futhi ama-slabs ezimbonini ahlala isikhathi eside ngoba imicu imunca amandla futhi igcine isakhiwo siqinile ngaphansi kwengcindezi.

Ukusebenza Okungcono Ezigabeni Ezincane

Izakhi zikakhonkolo ezizacile njengezimbondela, i-shotcrete linings, noma amaphaneli e-precast ngokuvamile awanamandla. Ukungeza 3-18 mm PVA imicu ibanika ukwesekwa okwengeziwe ngaphandle kokudinga inetha lensimbi. Imicu ihlangana kahle nokunamathisela usimende, ukwenza lezi zigaba ezingasindi ziqine ngokwanele izidingo zomhlaba wangempela.

Ifanele Umsebenzi Wokulungisa Nokubuyisela Inzuzo

Izakhiwo zikakhonkolo ezindala zivame ukudinga ukulungiswa. Ukhonkolo oqiniswe yivinylon isebenza kahle ekuxhumeni nasekuqiniseni. Inamathela ngokuqinile ezindaweni ezikhona futhi ihamba nazo njengoba amazinga okushisa eshintsha. Lokhu kunciphisa i-delamination futhi kuthuthukisa impilo yokulungisa.

Imvelo Izinzile futhi Iphephile

Ngokungafani neminye imicu yokwenziwa, PVA fibers ungagqwali. Zihlala zizinzile ezimeni ezimanzi noma ezine-alkaline ngaphakathi kokhonkolo. Futhi azikhiphi izinto eziyingozi, making them safe for indoor and outdoor use alike. Their compatibility with standard mixing and placing methods means no special tools or training are needed.

Isingeniso Senkampani
