1.I-calorimeter yokuskena umahluko ye-DSC-BS52ikakhulu ilinganisa kwaye ifunde iinkqubo zokunyibilika kunye nokwakheka kwekristale yezinto, ubushushu bokutshintsha kweglasi, inqanaba lokuphilisa le-epoxy resin, ukuzinza kobushushu/ixesha lokungenisa i-oxidation OIT, ukuhambelana kwe-polycrystalline, ubushushu bokusabela, i-enthalpy kunye nendawo yokunyibilika kwezinto, ukuzinza kobushushu kunye nekristale, utshintsho lwesigaba, ubushushu obuthile, utshintsho lwekristale yolwelo, i-kinetics yokusabela, ubumsulwa, kunye nokuchongwa kwezinto, njl.
I-DSC differential scanning calorimeter yindlela yokuhlalutya ubushushu esetyenziswa kakhulu kuphando lwesayensi nakwiindawo zoshishino, kwaye ibe sisixhobo esibalulekileyo sokuhlola iimpawu zobushushu zezinto. Ii-differential scanning calorimeters zifunda iimpawu zobushushu zezinto ngokulinganisa umahluko ekuhambeni kobushushu phakathi kwesampuli kunye nezinto ezisetyenzisiweyo ngexesha lokufudumeza okanye ukupholisa. Kwindawo yophando lwesayensi, ii-differential scanning calorimeters zisetyenziswa kakhulu. Umzekelo, kwicandelo lekhemistri, ingasetyenziselwa ukufunda iziphumo zobushushu beempendulo zeekhemikhali, ukuqonda iindlela zokuphendula kunye neenkqubo zekinetic. Kwindawo yesayensi yezinto, iteknoloji ye-DSC inokunceda abaphandi baqonde iiparameter ezibalulekileyo ezifana nokuzinza kobushushu kunye nobushushu bokutshintsha kweglasi yezinto, ukubonelela ngenkxaso enamandla kuyilo kunye nophuhliso lwezinto ezintsha. Kwindawo yezimboni, ii-differential scanning calorimeters nazo zidlala indima engenakutshintshwa. Ngeteknoloji ye-DSC, iinjineli zinokuqonda utshintsho olunokwenzeka ekusebenzeni kobushushu beemveliso ngexesha lokuvelisa nokusetyenziswa, ngaloo ndlela ziphucula inkqubo yemveliso kunye nolawulo lomgangatho. Ukongeza, i-DSC ingasetyenziselwa nolawulo lomgangatho wemveliso kunye nokuhlolwa kwezinto eziluhlaza ukuqinisekisa ukusebenza kunye nozinzo lwemveliso.
2.Isivavanyeli sokwanda kobushushu se-YY-1000Asisixhobo esichanekileyo esisetyenziselwa ukulinganisa utshintsho olulinganayo lwezinto xa zishushu, ikakhulu ukumisela iipropati zokwandiswa kunye nokucutheka kweentsimbi, iiseramikhi, iglasi, iiglaze, izinto ezichasayo kunye nezinye izinto ezingezizo ezesinyithi kumaqondo obushushu aphezulu.
Umgaqo osebenzayo we-coefficient ye-thermal expansion tester usekelwe kwi-expansion and contraction phenomenon yezinto ngenxa yotshintsho lobushushu. Kwisixhobo, isampuli ibekwa kwindawo enokulawula ubushushu. Njengoko ubushushu butshintsha, ubungakanani besampuli buya kutshintsha. Olu tshintsho lulinganiswa ngokuchanekileyo zii-sensors ezichanekileyo (ezifana nee-inductive displacement sensors okanye ii-LVDTS), eziguqulwa zibe ziisignali zombane, kwaye ekugqibeleni zicutshungulwe kwaye ziboniswe yisoftware yekhompyutha. I-thermal expansion coefficient tester idla ngokuxhotyiswa ngenkqubo yolawulo lwekhompyutha, enokubala ngokuzenzekelayo i-expansion coefficient, i-volume expansion, i-linear expansion amount, kwaye ibonelele ngedatha efana ne-temperature-expansion coefficient curve. Ukongeza, ezinye iimodeli eziphezulu zixhotyiswe ngemisebenzi yokurekhoda ngokuzenzekelayo, ukugcina kunye nokuprinta idatha, kunye nokuxhasa ukhuseleko lomoya kunye nemisebenzi yokucoca ulwelo ukuhlangabezana neemfuno ezahlukeneyo zovavanyo.
3.Umatshini wovavanyo lwe-elektroniki we-YYP-50KNEyona nto isetyenziswa kakhulu kuvavanyo lokuqina kwendandatho yeplastiki yombhobho, Umvavanyi wokuqina kwendandatho yeplastiki yombhobho usetyenziswa kakhulu ukuvavanya ukuqina kwendandatho kunye nokuguquguquka kwendandatho (isicaba) kunye nezinye iimpawu zoomatshini zemibhobho yeplastiki, imibhobho yefiberglass kunye nemibhobho yezinto ezidityanisiweyo.
Isivavanyeli sokuqina kwendandatho yeplastiki sisetyenziswa kakhulu ekumiseleni ukuqina kwendandatho yemibhobho ye-thermoplastic kunye nemibhobho ye-fiberglass eneziqendu ezinqamlezileyo ezijikelezileyo. Sihlangabezana neemfuno zemibhobho ye-PE eneendonga ezimbini, imibhobho yamanxeba kunye nemigangatho eyahlukeneyo yemibhobho, kwaye sinokugqiba iimvavanyo ezinje ngokuqina kwendandatho yepayipi, ukuguquguquka kwendandatho, ukuthamba, ukugoba kunye nokuwelda amandla okutsalwa. Ukongeza, sixhasa ukwandiswa komsebenzi wovavanyo lwe-creep ratio, osetyenziselwa ukulinganisa imibhobho yeplastiki enobubanzi obukhulu kunye nokulinganisa ukuncitshiswa kokuqina kwayo kwendandatho ngokuhamba kwexesha phantsi kweemeko zokungcwaba ezinzulu ixesha elide.
