1.I-calorimeter yokuskena umehluko ye-DSC-BS52ikakhulukazi ilinganisa futhi ifunde izinqubo zokuncibilika kanye nokwenza i-crystallization yezinto, izinga lokushisa lokuguquka kwengilazi, izinga lokwelapha le-epoxy resin, isikhathi sokungeniswa kokuzinza kokushisa/i-oxidation OIT, ukuhambisana kwe-polycrystalline, ukushisa kokusabela, i-enthalpy kanye nephuzu lokuncibilika kwezinto, ukuzinza kokushisa kanye ne-crystallinity, ukuguquka kwesigaba, ukushisa okuthile, ukuguquka kwekristalu eliwuketshezi, i-kinetics yokusabela, ubumsulwa, kanye nokuhlonza izinto, njll.
I-DSC differential scanning calorimeter iyindlela yokuhlaziya ukushisa esetshenziswa kabanzi ocwaningweni lwesayensi kanye nasemasimini ezimboni, futhi isibe ithuluzi elibalulekile lokuhlola izakhiwo zokushisa zezinto. Ama-calorimeter okuskena ahlukene afunda izakhiwo zokushisa zezinto ngokulinganisa umehluko ekugelezeni kokushisa phakathi kwesampula kanye nezinto ezibhekiselwe kuzo ngesikhathi sokushisa noma ukupholisa. Emkhakheni wocwaningo lwesayensi, ama-calorimeter okuskena ahlukene asetshenziswa kabanzi. Isibonelo, emkhakheni wekhemistri, ingasetshenziswa ukutadisha imiphumela yokushisa yokusabela kwamakhemikhali, ukuqonda izindlela zokusabela kanye nezinqubo ze-kinetic. Emkhakheni wesayensi yezinto, ubuchwepheshe be-DSC bungasiza abacwaningi ukuqonda amapharamitha abalulekile njengokuzinza kokushisa kanye nokushisa kokushintsha kwengilazi kwezinto, okuhlinzeka ngokusekelwa okuqinile kokuklama nokuthuthukiswa kwezinto ezintsha. Emkhakheni wezimboni, ama-calorimeter okuskena ahlukene nawo adlala indima engenakuphikwa. Ngobuchwepheshe be-DSC, onjiniyela bangaqonda izinguquko ezingaba khona ekusebenzeni kokushisa kwemikhiqizo ngesikhathi sokukhiqiza nokusetshenziswa, ngaleyo ndlela benze ngcono inqubo yokukhiqiza kanye nokulawulwa kwekhwalithi. Ngaphezu kwalokho, i-DSC ingasetshenziswa futhi ekulawuleni ikhwalithi yomkhiqizo kanye nokuhlolwa kwezinto zokusetshenziswa ukuqinisekisa ukusebenza komkhiqizo kanye nokuqina.
2.Isihloli se-coefficient yokwandisa ukushisa se-YY-1000Aiyithuluzi elinembile elisetshenziselwa ukukala izinguquko zobukhulu bezinto lapho zishiswa, ikakhulukazi ukunquma izakhiwo zokwanda kanye nokufinyela kwezinsimbi, izinto zobumba, ingilazi, ama-glaze, izinto eziphikisayo kanye nezinye izinto ezingezona ezensimbi emazingeni okushisa aphezulu.
Umgomo wokusebenza we-coefficient ye-thermal expansion tester usekelwe kulokho okwenzeka ekukhuleni nasekuncipheni kwezinto ngenxa yokushintsha kwezinga lokushisa. Ethuluzini, isampula ibekwa endaweni engalawula izinga lokushisa. Njengoba izinga lokushisa lishintsha, ubukhulu besampula buzoshintsha futhi. Lezi zinguquko zilinganiswa ngokunembile yizinzwa ezinembayo ephezulu (njengezinzwa zokufuduka ezishintshayo noma i-LVDTS), eziguqulwa zibe amasignali kagesi, futhi ekugcineni zicutshungulwe futhi ziboniswe yisoftware yekhompyutha. I-thermal expansion coefficient tester ivame ukuhlonyiswa ngohlelo lokulawula ikhompyutha, olungabala ngokuzenzakalelayo i-expansion coefficient, i-volume expansion, inani lokukhulisa eliqondile, futhi lunikeze idatha efana ne-temperature-expansion coefficient curve. Ngaphezu kwalokho, amanye amamodeli aphezulu ahlonyiswe ngemisebenzi yokurekhoda ngokuzenzakalelayo, ukugcina nokuphrinta idatha, futhi asekele ukuvikelwa komkhathi kanye nemisebenzi yokuhlanza ukuze kuhlangatshezwane nezidingo ezahlukene zokuhlola.
3.Umshini Wokuhlola We-elekthronikhi We-YYP-50KNesetshenziswa kakhulu ekuhlolweni kokuqina kwendandatho yepayipi lepulasitiki, Umhloli wokuqina kwendandatho yepayipi lepulasitiki usetshenziswa kakhulu ukuhlola ukuqina kwendandatho kanye nokuguquguquka kwendandatho (okuyisicaba) kanye nezinye izakhiwo zemishini zamapayipi epulasitiki, amapayipi e-fiberglass kanye namapayipi ezinto ezihlanganisiwe.
Isihloli sokuqina kwendandatho yepayipi lepulasitiki sisetshenziswa kabanzi ekunqumeni ukuqina kwendandatho yamapayipi e-thermoplastic namapayipi e-fiberglass anezingxenye ezivundlile. Sihlangabezana nezidingo zamapayipi e-PE anodonga oluphindwe kabili, amapayipi amanxeba kanye nezindinganiso ezahlukene zamapayipi, futhi singaqedela ukuhlolwa okufana nokuqina kwendandatho yepayipi, ukuguquguquka kwendandatho, ukuthamba, ukugoba kanye nokushisela amandla okudonsa. Ngaphezu kwalokho, sisekela ukwanda komsebenzi wokuhlola isilinganiso se-creep, osetshenziselwa ukukala amapayipi epulasitiki amakhulu agqitshwe futhi silingise ukuncishiswa kokuqina kwendandatho yawo ngokuhamba kwesikhathi ngaphansi kwezimo zokungcwaba ezijulile zesikhathi eside.
