Kumashishini aqala kwiimoto ukuya kwimpahla yokunxiba, ukuqinisekisa ukuba izinto zihlala ixesha elide kubalulekile. Kulapho keumatshini wokuvavanya ukukralaidlala indima ebalulekileyo. Ekwaziwa ngokuba ngumvavanyi wokukrala, esi sixhobo sivavanya indlela izinto ezimelana ngayo nokuguguleka nokungqubana ngokuhamba kwexesha. Makhe sihlolisise umgaqo-nkqubo waso wokusebenza, inkqubo, kunye nokusetyenziswa.

Umgaqo woVavanyo lwe-Abrasion

Umgaqo ophambili wovavanyo lokukrala kukufanisa iimeko zokuguguleka zehlabathi lokwenyani ngokubeka iisampulu zezinto phantsi kokungqubana okulawulwayo. Umatshini ulinganisa ukumelana nokuwohloka komphezulu, unceda abavelisi ukuba baqikelele ixesha lokuphila kwemveliso kunye nomgangatho wayo. Nokuba zivavanya amalaphu, iingubo, okanye iipolymers, injongo kukulinganisa ukulahleka kwezinto, ukufiphala kombala, okanye utshintsho kwisakhiwo emva kokudibana okuphindaphindiweyo.

Usebenza njani umatshini wokuvavanya ukurhawuzelelwa?

Uvavanyo oluqhelekileyo lokukrala lubandakanya la manyathelo alandelayo:

1. Ukulungiselela iSampuli

Isampulu yezinto eziphathekayo (umz., ilaphu, iplastiki, okanye umphezulu opeyintiweyo) isikwa ngokwemilinganiselo emiselweyo. Oku kuqinisekisa ukuhambelana kuzo zonke iimvavanyo.

2. Ukufakela iSampuli

Isampulu ibotshelelwe ngokukhuselekileyo kwiqonga lomvavanyi. Kubavavanyi abajikelezayo abanjengoTaber Abraser, isampulu ibekwa kwi-turntable ejikelezayo.

3. Ukukhetha Izinto Ezirhabaxa

Amavili arhabaxa, amaphepha okugquma, okanye izixhobo zokuhlikihla zikhethwa ngokusekelwe kumgangatho wovavanyo (umz., i-ASTM, i-ISO). Ezi zinto zisebenzisa ukungqubana okulawulwayo kwisampulu.

4. Ukusebenzisa Umthwalo kunye Nokunyakaza

Umatshini usebenzisa umthwalo othile othe nkqo (umz., iigram ezingama-500–1,000) kwinto erhabaxa. Kwangaxeshanye, isampuli idlula kwintshukumo ejikelezayo, ethe nkqo, okanye ejikelezayo, nto leyo edala uqhagamshelwano olurhabaxa oluphindaphindwayo.

5. Ukuphunyezwa komjikelo

Uvavanyo lusebenza kwimijikelo echazwe kwangaphambili (umz., ukujikeleziswa kwe-100–5,000). Abavavanyi abaphambili baquka ii-sensors zokujonga ukuguguleka ngexesha langempela.

6. Uvavanyo Emva koVavanyo

Emva kovavanyo, isampuli iyahlolwa ukuba ayinciphisi ubunzima, ayinciphisi ukutyeba, okanye ayiwonakalisi umphezulu. Idatha ithelekiswa nemilinganiselo yoshishino ukuze kuqinisekiswe ukuba izinto zifanelekile na.

Iintlobo zeendlela zovavanyo lwe-Abrasion

Iimatshini zovavanyo ezahlukeneyo zokukralaukuhlangabezana neemfuno ezithile:

●I-Taber Abraser:Isebenzisa amavili arhabaxa ajikelezayo kwizinto ezisicaba ezifana neentsimbi okanye ii-laminate.

●Umvavanyi waseMartindale:Ilinganisa ukuguguleka kwelaphu ngokugudla okujikelezayo.

●Isivavanyeli se-DIN Abrasion:Ilinganisa ukuqina kwerabha okanye i-sole isebenzisa ivili lokusila.

Usetyenziso lwabaVavanyi be-Abrasion

Ezi matshini zibaluleke kakhulu kwezi zinto zilandelayo:

●Iimoto:Ukuvavanya amalaphu ezihlalo, iideshibhodi, kunye neengubo.

●Amalaphu:Ukuvavanya ukuqina kwempahla yokunxiba, iiyunifomu, okanye iimpahla zemidlalo.

●Ukupakisha:Ukuvavanya ukumelana kweelebheli ekuphathweni nasekuthunyelweni.

●Ulwakhiwo:Ukuhlalutya izigqubuthelo zomgangatho okanye zodonga.

Kutheni Ukubekwa Kwemigangatho Kubalulekile

Abavavanyi be-AbrasionLandela imigaqo engqongqo (umz., i-ASTM D4060, i-ISO 5470) ukuqinisekisa ukuba iyaphindaphindeka. Ukulinganisa kunye neendawo ezilawulwayo (ubushushu, ukufuma) kunciphisa ukuguquguquka, okwenza iziphumo zithembeke kwi-R&D kunye nokuhambelana.
