IYY8503cukungxamaumvavanyi kwaye i YY109 Ngokuzenzekelayo umvavanyi wamandla okuqhumazizixhobo ezibalulekileyo zokuvavanya iimpawu zomzimba zephepha, ibhodi yamaphepha kunye neebhokisi. Zidlala indima ebalulekileyo ekulawuleni umgangatho wezinto zokupakisha. Nazi iindlela zokusebenzisa kunye namanyathelo okhuseleko kwezi zixhobo zimbini.
Ukusetyenziswa kweUmvavanyi wokuCrush:
Iumvavanyi wokutyumza isetyenziswa kakhulu ukulinganisa amandla oxinzelelo lweringi(i-RCT), amandla oxinzelelo oluphezulu(ECT), amandla okubopha(I-PAT) kunye namandla okucinezelwa athe tyaba ebhodi yephepha(i-FCT)Indlela yokusebenzisa yile ilandelayo:
1. Umsebenzi wokulungiselela:
1). Qinisekisa ukuba indawo yokusebenza yesixhobo iyahlangabezana neemfuno, apho ubushushu buqala kwi (20 ± 10)℃.
2). Jonga ukuba ubungakanani bepleyiti yoxinzelelo kunye nokubetha kovavanyo lwesixhobo kuyahambelana na nemigangatho yovavanyo.
2. Ukulungiselela isampuli:
1). Ngokwemigangatho yovavanyo, sika isampuli ibe kubungakanani obuchaziweyo.
2). Qinisekisa ukuba icala elirhabaxa lesampuli lithe nkqo kwiipleyiti ezimbini zoxinzelelo zomvavanyi woxinzelelo.
3. Inkqubo yovavanyo:
1). Beka isampuli phakathi kweepleyiti ezimbini zoxinzelelo zomvavanyi woxinzelelo.
2). Misela isantya sovavanyo, esimisiweyo kwi-12.5 ± 3mm/min, okanye silungiswe ngesandla sibe yi-5 - 100mm/min.
3). Faka uxinzelelo kwisampulu ide iwele.
4. Ukufundwa kweziphumo:
1). Bhala phantsi uxinzelelo oluphezulu olunokumelana nesampuli, oluyimandla oxinzelelo lwesampuli.
2). Iziphumo zovavanyo zingaphuma ngomsebenzi wokuprinta idatha.
Ukusetyenziswa kwe-Burst Strength Tester:
Isivavanyeli samandla okuqhuma sisetyenziswa kakhulu ukulinganisa amandla okuqhuma kwephepha. Indlela yokusebenzisa yile ilandelayo:
1. Amalungiselelo:
1). Qinisekisa ukuba indawo yokusebenza yesixhobo iyahlangabezana neemfuno, kunye nobushushu obuphakathi koluhlu lwe (20 ± 10)℃.
2). Jonga umthombo wamandla wesixhobo ukuqinisekisa ukuchaneka kwaso, ukuchaneka kwaso kufikelela kwi-0.02%.
2. Ukulungiselela isampuli:
1). Ngokomgangatho wovavanyo, sika isampuli ibe bukhulu obuchaziweyo.
2). Qinisekisa ukuba umphezulu wesampuli uthe tyaba kwaye awunaziphene zicacileyo.
3. Inkqubo yovavanyo:
1). Faka isampuli kwisixhobo sokuvavanya amandla okuqhuma.
2). Faka uxinzelelo kwisampulu ide iqhume.
3). Bhala phantsi ixabiso eliphezulu loxinzelelo ngexesha lokuqhekeka kwesampuli.
4. Ukufundwa kweziphumo:
1). Bala amandla okuqhuma kwesampulu, ngesiqhelo kwiiyunithi ze-kPa okanye ze-psi.
2). Iziphumo zovavanyo zingaphuma ngomsebenzi wokuprinta idatha.
Amanqaku Okunika Ingqwalasela:
1. Ukulinganisa Izixhobo:
1).Lungisa rhoqo i-compression tester kunye ne-burst strength tester ukuqinisekisa ukuchaneka kweziphumo zovavanyo.
2)Ukulinganisa kufuneka kwenziwe ngokuhambelana nemigangatho efanelekileyo, efana ne-ISO2758 "Iphepha - Ukumisela Amandla Okuqhuma" kunye ne-GB454 "Indlela Yokufumanisa Amandla Okuqhuma Kwephepha".
2. Ukucwangciswa kweSampuli:
1)Iisampulu mazigcinwe kwindawo eqhelekileyo ukuze zingafumani ukufuma okanye ubushushu.
2)Ubungakanani kunye nokuma kweesampuli kufuneka kuhambelane nemigangatho yovavanyo ukuqinisekisa ukuthelekiswa kweziphumo zovavanyo.
3. Ukusebenza ngokukhuselekileyo:
1)Abaqhubi kufuneka bafumane uqeqesho lobuchwephesha kwaye baqhelane neendlela zokusebenzisa kunye neenkqubo zokusebenza ngokhuseleko lwezixhobo.
2)Ngexesha lenkqubo yovavanyo, lumka ukuthintela ukuba iisampuli zingaphumi okanye ukungasebenzi kakuhle kwezixhobo kubangele ukwenzakala.
Ngokusebenzisa ngokuchanekileyo i-compression tester kunye ne-burst strength tester, umgangatho wokufumanisa iphepha, ibhodi yamaphepha, kunye neebhokisi unokuphuculwa ngempumelelo, ukuqinisekisa ukuba ukusebenza kwezixhobo zokupakisha kuyahlangabezana neemfuno.
