Isikhokelo esiBanzi sePlastiki yoVavanyo lwe-Tensile kwiiFactory zokuMonda isitofu

Intshayelelo:

Uvavanyo lokuqina kwamalungu ePlastiki abambe ukubaluleka okukhulu kwindawo yeefektri zokubumba inaliti.Le nkqubo yokulawula umgangatho ibalulekileyo yenzelwe ukuvavanya ngokucokisekileyo iipropathi zoomatshini kunye nokusebenza kwamalungu eplastiki.Ngokubeka ezi mathiriyeli kumandla azolula alawulwayo, abavelisi banokuwalinganisa ngokuchanekileyo amandla kunye nokuqina kwabo, beqinisekisa ukuba iimveliso zokugqibela ziyahlangabezana nemigangatho engqongqo yoshishino kunye nolindelo lwabathengi.Esi sikhokelo sibanzi sihlalutya injongo, inkqubo, kunye nokubaluleka kwamalungu eplastiki ovavanyo oluqinileyo, sikhanyisela indima yawo ebalulekileyo ekugcineni umgangatho wemveliso ephezulu.

1. Injongo yoVavanyo lwe-Tensile:

Eyona njongo iphambili yovavanyo lokuqina kwenxalenye yeplastiki kukufumanisa iimpawu ezibalulekileyo zoomatshini bezinto zeplastiki, kubandakanya amandla abo okugqibela, amandla esivuno, ubude ngexesha lekhefu, kunye nemodyuli yabancinci.Ezi parameters zidlala indima ebalulekileyo ekuvavanyeni imfezeko yesakhiwo semathiriyeli, ukuqikelela indlela yokuziphatha kwayo phantsi komthwalo, kunye nokuqinisekisa ukufaneleka kwayo kwizicelo ezithile.Ngokufumana idatha echanekileyo ngovavanyo lwe-tensile, abavelisi banokwenza izigqibo ezinolwazi malunga nokukhethwa kwezinto kunye nokuphuculwa koyilo, ekugqibeleni okukhokelela ekusebenzeni kwemveliso kunye nokuthembeka.

2. Uvavanyo loLungiso lweSampuli:

Uvavanyo lwe-tensile lufuna ukulungiswa kwemizekelo yovavanyo oluchanekileyo kunye nommeli.Le mizekelo iqhele ukwenziwa ngoomatshini okanye ibunjwe ukusuka kumacandelo eplastiki avavanywayo, ngokulandela imilinganiselo ethile kunye nolungelelwaniso oluchazwe kwimigangatho efanelekileyo efana ne-ASTM D638 okanye i-ISO 527. Ukulungiswa ngononophelo kwemizekelo yovavanyo kuqinisekisa iziphumo ezithembekileyo nezingaguqukiyo ngexesha lovavanyo.

3. IsiXhobo sokuVavanya i-Tensile:

Embindini wenxalenye yeplastiki yovavanyo lokuqina kukho umatshini wovavanyo wendalo yonke (UTM).Esi sixhobo sikhethekileyo sinemihlathi emibini ebambekayo - enye ibambe ngokuqinileyo isampula yovavanyo kwaye enye isebenzise amandla okutsala alawulwayo.Iirekhodi zesoftware ye-UTM ephucukileyo kwaye ihlalutya amandla asetyenzisiweyo kunye nedatha ye-deformation ehambelanayo ngexesha lovavanyo, ukuvelisa i-curves ebalulekileyo yoxinzelelo.

4. Inkqubo yoVavanyo lwe-Tensile:

Olona vavanyo lwe-tensile luqala ngokucinezela ngokukhuselekileyo isampuli yovavanyo ngaphakathi kwe-UTM yokubamba, ukuqinisekisa ukuhanjiswa okufanayo kwamandla asetyenziswayo.Uvavanyo luqhutyelwa kwisantya esiqhubekayo se-crosshead, ngokuthe ngcembe solula i-specimen de ifike kwindawo yokuphuka.Kuyo yonke le nkqubo, i-UTM iqhubeka irekhoda amandla kunye nedatha yokufuduswa, ivumela uhlalutyo oluchanekileyo lokuziphatha kwezinto phantsi koxinzelelo lwe-tensile.

5. Ukuqokelelwa kweenkcukacha kunye noHlalutyo:

Emva kovavanyo, idatha erekhodiweyo ye-UTM icutshungulwa ukuvelisa i-curve-strain curve, umboniso osisiseko wegraphical wempendulo yezinto kwizinto ezisetyenzisiweyo.Ukusuka kweli jiko, iipropathi zoomatshini ezibalulekileyo ziyathathwa, kubandakanya ukomelela kokugqibela, amandla esivuno, ubude ngexesha lekhefu, kunye nemodyuli yoNcinci.Ezi parameters ezinokulinganiswa zinika ukuqonda okubalulekileyo kwindlela yokuziphatha komatshini, okwenza abavelisi benze izigqibo eziqhutywa yidatha kuphuhliso lwabo lwemveliso kunye neenkqubo zokulawula umgangatho.

6. Ukutolika kunye noLawulo loMgangatho:

Idatha efunyenwe kuvavanyo lwe-tensile ihlalutywa ngobuchule ukuvavanya ukuba ingaba imathiriyeli yeplastiki iyahlangabezana neenkcukacha ezifunekayo kunye nemigangatho.Ukuba iziphumo ziwela phakathi koluhlu olufunwayo, iinxalenye zeplastiki zithathwa njengezilungele ukusetyenziswa kwazo.Ngokwahlukileyo koko, nakuphi na ukutenxa okanye iintsilelo zikhuthaza abavelisi ukuba benze uphuculo oluyimfuneko okanye uhlengahlengiso, beqinisekisa ukuveliswa kwezixhobo zeplastiki ezikumgangatho ophezulu.

Isiphelo:

Amalungu ePlastiki avavanya amandla ami njengentsika yolawulo lomgangatho kwiifektri zokubumba inaliti.Ngokubeka izinto zeplastiki kumandla olula okulawulwayo kunye nokuvavanya ngokucokisekileyo iimpawu zabo zomatshini, abavelisi banokuqinisekisa ukuba iimveliso zabo ziyahlangabezana nemigangatho ephezulu yoshishino.Bexhobe ngedatha echanekileyo, abavelisi banokwenza izigqibo ezinolwazi malunga nokukhethwa kwezinto, ukuguqulwa koyilo, kunye nokuphuculwa kwemveliso iyonke, ekugqibeleni banikeze iinxalenye zeplastiki ezithembekileyo nezisebenza kakhulu kubathengi babo.
