Yimiphi imiphumela i-polymer powder ehlakazeka kabusha enayo emandleni odaka?

Ukuhlanganisa izimpushana ze-polymer ezihlakazeka kabusha (i-RPP) ekwenziweni kodaka kuthinta kakhulu izici zamandla zezinto eziwumphumela. Lesi sihloko sihlola imiphumela ye-RPP emandleni odaka, okuhlanganisa ithonya lawo emandleni acindezelayo, amandla aguquguqukayo, amandla okunamathela, kanye nokumelana nomthelela.

1. Amandla Acindezelayo:

Amandla acindezelayo ayimpahla eyisisekelo yodaka, ebonisa amandla ayo okumelana nemithwalo ye-axial. Ukwengezwa kwama-RPP kungathuthukisa amandla okucindezela ngokusebenzisa izindlela ezimbalwa:

Ukubumbana Okukhulisiwe:

Ama-RPP asebenza njengama-ejenti abophayo, akhuthaza ukuhlangana okungcono phakathi kwezinhlayiya zodaka. Lokhu kuhlanganiswa kwezinhlayiyana okuthuthukisiwe kunomthelela emandleni aphezulu okucindezela ngokunciphisa ama-void angaphakathi nokuthuthukisa ubuqotho besakhiwo bezinto ezibonakalayo.

Ukumuncwa kwamanzi okwehlisiwe:

Ama-RPP athuthukisa ukugcinwa kwamanzi odaka, okuvumela ukugeleza okusebenzayo kwezinto zikasimende. I-hydration efanele iholela kuma-microstructures aminyene ane-void embalwa, okuholela kumandla aphezulu okucindezelayo kanye namazinga aphansi okumunca amanzi.

Amandla e-Flexural athuthukisiwe:

Ukuvumelana nezimo okunikezwa ama-RPP kungathonya ngokungaqondile amandla okucindezela ngokuvimbela ama-microcracks ukuthi angasakazeki futhi enze buthaka okokusebenza. Ama-mortar aqukethe ama-RPP ngokuvamile abonisa amandla athuthukisiwe okuguquguquka, ahambisana nokumelana okuthuthukisiwe kwamandla okucindezela.

2. Amandla Aguquguqukayo:

Amandla e-Flexural akala ikhono lempahla lokumelana nokugoba noma ukuwohloka ngaphansi kwemithwalo esetshenzisiwe. Ama-RPP afaka isandla ekuthuthukiseni amandla okuguquguquka odakeni ngokusebenzisa lezi zindlela ezilandelayo:

Amandla Ebhondi Akhulisiwe:

Ama-RPP athuthukisa ukunamathela phakathi kwezingxenye zodaka nendawo engaphansi, okuholela kumabhondi aqinile nokuncipha kwe-delamination. Lawa mandla ebhondi athuthukisiwe ahumusha ukumelana okuphezulu nokugoba kanye nezingcindezi eziqinile, ngaleyo ndlela kuthuthukisa amandla okuguquguquka.

Ukubumbana Okuthuthukisiwe:

Izici ezihlangene zodaka olushintshiwe lwe-RPP zisiza ukusabalalisa imithwalo esetshenzisiwe ngokulinganayo kusiphambano somsebenzisi. Lokhu nokusatshalaliswa kunciphisa ukugxila kwengcindezi yendawo futhi kuvimbela ukwehluleka ngaphambi kwesikhathi, okuholela kumandla aphezulu wokuguquguquka.

3. Amandla Okunamathelayo:

Amandla okunamathela asho isibopho esiphakathi kodaka ne-substrate. Ama-RPP adlala indima ebalulekile ekwandiseni amandla okunamathela ngalezi zindlela ezilandelayo:

Ukunamathela Okuthuthukisiwe:

Ama-RPP akhuthaza ukunamathela okungcono ngokwenza ifilimu encane, eguquguqukayo ezindaweni ezingaphansi kwe-substrate, ethuthukisa indawo yokuxhumana futhi ikhuthaze ukuhlangana kobuso. Lokhu kunamathela okuthuthukisiwe kuvimbela ukubopha futhi kuqinisekisa ukuxhumana okuqinile phakathi kodaka ne-substrate.

Ama-Shrinkage Cracks ancishisiwe:

Izinto eziguquguqukayo kanye nokugcinwa kwamanzi kwama-RPP zisiza ukunciphisa ukuqhekeka kodaka, okungafaka engozini amandla okunamathela. Ngokunciphisa ukwakheka nokusakazeka kokuqhekeka, ama-RPP anikela kumabhondi anamathelayo aqinile futhi ahlala isikhathi eside.

4. Ukumelana Nomthelela:

Ukumelana nomthelela kulinganisa ikhono lempahla lokumelana nemithelela ezumayo, enamandla amakhulu ngaphandle kokuphuka noma ukuphuka. Ama-RPP athuthukisa ukumelana nomthelela wodaka ngokusebenzisa lezi zindlela ezilandelayo:

Ukuqina Okungeziwe:

Udaka olushintshwe i-RPP lubonisa ukuqina okuphezulu ngenxa yokuguquguquka nokuguquguquka okuthuthukisiwe. Lokhu kuqina okwenyukile kuvumela okokusebenza ukuthi kumunce futhi kuhlakaze amandla omthelela ngempumelelo kakhudlwana, kunciphisa amathuba okuphuka noma ukwehluleka lapho kunomthelela.

Ukuqina Okuthuthukisiwe:

Ukuqina okunikezwa ama-RPP kwandisa impilo yesevisi yodaka, okuqinisekisa ukusebenza kwesikhathi eside ngaphansi kwezimo eziyinselele. Lokhu kuqina okuthuthukisiwe kuhumusha ekumelaneni okuphezulu nokulimala komthelela, ukuhuzuka, nezinye izinhlobo zokucindezelwa komshini.

Sengiphetha, izimpushana ze-polymer ezihlakazeka kabusha zidlala indima ebalulekile ekwandiseni amandla odaka, okuhlanganisa amandla acindezelayo, amandla aguquguqukayo, amandla okunamathela, kanye nokumelana nomthelela. Ngokuthuthukisa ukubumbana, ukunamathela, nokuqina, ama-RPP afaka isandla ekuthuthukiseni ukwakheka kodaka olusebenza kahle olufanele uhla olubanzi lwezinhlelo zokusebenza zokwakha.
