Iipropati zoomatshini zeBasalt Fiber ezinqunqiweyo imicu yekhonkrithi
INTSHAYELELO YEMVELISO
Ikhonkrithi, njengesixhobo sokwakha esisetyenziswa kakhulu kubunjineli bokwakha, ineempawu ezilungileyo zoomatshini, kodwa ngokuqhubeka kokusetyenziswa kobuchwephesha bobunjineli, ukusilela kweempawu zayo ezisisiseko zoomatshini kuyavela kancinci kancinci. Ngenxa yeempawu eziphantsi zokuqina kokuxinana kwesinye kwishumi kuphela samandla okuxinana, okubangela ukuba amalungu enkqubo yokuxinana athambekele ekuqhekekeni, nto leyo enciphisa ngokuthe ngqo ukuqina kwezixhobo, nto leyo enciphisa ububanzi bokusetyenziswa kwazo. Izinto zekhonkrithis. Ukuphucula iimpawu zokusebenza kobunjineli bekhonkrithi nokusombulula iingxaki ekusetyenzisweni kwekhonkrithi, iingcali beziphucula ukusebenza kwekhonkrithi.izixhobo zekhonkrithi kangangeminyaka emininzi kwaye zifumene iziphumo zesigaba ngesigaba, ezinje ngokongezwa kwezinto ezidityanisiweyo, ukulungisa umlinganiselo wokuxuba, ukuphucula inkqubo yemveliso kunye neendlela zokulungisa.
1. Izixhobo zovavanyo kunye neendlela zovavanyo
Kukhethwe isamente ye-silicate eqhelekileyo ye-P. O 42.5, enamandla oxinzelelo angama-28d angama-48.3MPa kunye namandla okuguquguquka angama-28d angama-8.2MPa. Isanti ephakathi ene-fineness modulus engama-2.5-2.6 isetyenziswe njenge-fine aggregate, enobunzima obubonakalayo obuyi-1996kg/m3. Ilitye elityumkileyo eliqhubekekayo eliyi-5-27mm lisetyenziswe njenge-coarse aggregate, enobunzima obubonakalayo obuyi-2737kg/m3. Kusetyenziswe izinga lokunciphisa amanzi elingama-40%. Kusetyenziswe i-40% ye-Sika polycarboxylic acid esebenza kakuhle kakhulu ekunciphiseni amanzi. Ubude be imicu eqoshiweyo yefayibha yebasalt imalunga ne-30mm, ububanzi be-monofilament bumalunga ne-15um, uxinano yi-2.7g/cm3, i-modulus yokuthamba yi-95-120MPa, amandla okutsalwa yi-3300-4500MPa, kwaye ubude ngexesha lokuqhekeka bumalunga ne-2.5-30%.
Ukulingana okufanelekileyo okusetyenzisiweyo kolu vavanyo kuboniswe kwiTheyibhile 1. Uvavanyo lokuxinzelela lusetyenziswa ngokweMigangatho yeeNdlela zoVavanyo lweePropathi zoMechanical zeKhonkrithi eQhelekileyo. Uvavanyo lokuxinzelela lusebenzisa iisampulu zetyhubhu eziyi-100×100×100mm, iisampulu ezi-3 kwiqela ngalinye, ukunyibilikisa okuqhelekileyo okuyi-28d.

2. Tngamanyathelo
(1) qala ngokusula isiqwenga sovavanyo esiza kuvavanywa emva kokujonga inkangeleko nokulinganisa ubungakanani, ngokuchanekileyo kum. Ukungalingani komphezulu we-sampuli kufikelela kwi-100mm, impazamo ayidluli kwi-0.5mm, kwaye umphezulu we-bearing kunye nokungahambi kakuhle okukufutshane akufuneki kube ngaphezulu kweemfuno ze-degree ye-1 degree;
(2) i-axis yesampuli yomatshini wovavanyo ehambelana nombindi wepleyiti yoxinzelelo phantsi komatshini wovavanyo. Vula umatshini wovavanyo, xa ipleyiti yoxinzelelo oluphezulu kunye nesiqwenga sovavanyo zivala, lungisa inkxaso, ukuze amandla afane;
(3) inkqubo yokulayisha ukuze ihlale iqhubeka kwaye ifana, isantya sokulayisha sovavanyo sithatha i-12kN / s-18kN / s; (4) bhala umthwalo ophezulu, ochanekileyo ukuya kwi-0.1MPa.
3. Iziphumo zovavanyo kunye nohlalutyo
Njengoko kunokubonwa kwiTheyibhile 2, amandla okuxinana ekhonkrithi angama-7d kunye nokwanda kwe I-Basalt Iifayibha zibonisa iimpawu zokungatshintshi ukuya ekunciphiseni kancinci kancinci, okubangelwa kakhulu kukongeza iifayibha ze-basalt, kwiifayibha kunye nesamente ezenziwe kwindawo yokudibanisa ukuvelisa umphezulu obuthathaka, kwaye ngokwanda kobuninzi bokuxuba iifayibha, olu hlobo lomphezulu obuthathaka luyaqhubeka nokwanda, ngoko ke amandla okuxinana kwe-cubic ngokwendalo ayaqhubeka nokwehla. Amandla okuxinana ekhonkrithi angama-28d kunye nokwanda komthamo wefayibha ye-basalt abonisa umkhwa wokunyuka kokuqala uze unciphe, isizathu sokwanda kokuqala sisixa esincinci se-doped.imicu ye-basalt zidlala indima ekudibaniseni ukuya kuthi ga kwinqanaba elithile ekunciphiseni ukuguquguquka kwekhonkrithi ngokwayo, ngelixa kwangaxeshanye zonyusa umphezulu obuthathaka xa kuthelekiswa nokwanda kwamandla angama-28d ukuze ube mncinci kakhulu, nto leyo ekusebenzeni ngokubanzi kwamandla yonyuka.
