Umtjhini wokwenza isivalo seplastiki ngokuqathaniswa nomtjhini wokwenza ikopi: Ngimuphi umehluko?

I-Whai mtjhini wokwenza isivalo

Umtjhini wokwenza ithreyi yeplastiki / isivalo umkhiqizi wasungulwa ngokusekelwe ebuchwephesheni obuvuthiweko bokwenza imitjhini yeplastiki, le yimodeli ethuthukisiweko, ehlakaniphileko begodu kulula ukuyisebenzisa. Ilungele khulu ukubunjwa kwe-PET, i-PS, i-PVC namanye amaphepha weplastiki.

Yini umtjhini wokwenza ikopi yeplastiki

I umtjhini wokwenza ikopi mtjhini owenzelwe ukwenza iinkomitjhana. Ibonakala ngokusebenza kuhle, ukunemba, ukulula kanye nebelo. Kokuthoma, umtjhini wokwenza iinkomitjhana usebenzisa ithekhnoloji ethuthukileko begodu ungaqeda inani elikhulu leenkomishi ngesikhathi esifitjhani, okwenza ngcono khulu ukusebenza kuhle kokukhiqiza. Kwesibili, umtjhini wokwenza ikopi ungalawula ngokunembileko ubukhulu, ijamo nokuqina kwekopi, ukuqinisekisa ikhwalithi nokunzinza kwekopi. Ngaphezu kwalokho, umtjhini wokwenza ikopi kulula ukuwusebenzisa.

Yini umehluko?

Iimbawo:

Umtjhini wokwenza iinkomitjhana zeglasi yeplastiki ulungele ukubumba i-PP, i-PET, i-PS, i-PLA namanye amaphepha weplastiki ukukhiqiza imikhiqizo ehlukileko yokupakisha njengamabhokisi, amapuleti, iinkomitjhana, iintja, izivalo, njll.

Umtjhini wokwenza isivalo usetjenziswa khulu ekwenzeni amakhava, amathreyi, amapuleti, amabhokisi.

Ukutjhwaba

Ukuthatha ubuhle bomtjhini wokupakisha we-aluminiyamu-weplastiki kanye nomtjhini wokubumba iplastiki, umtjhini wokwenza isivalo wamukela ukwakheka okuzenzakalelayo, ukubhoboza nokusika njengoba izakhiwo ezikhethekileko zomkhiqizo zidinga abasebenzisi. Ngethekhnoloji ethuthukileko, ukusebenza okuphephileko nokulula, ukubalekela ukusetjenziswa kwabasebenzi okubangelwa kutjhwaba ngezandla nokusilaphazeka okubangelwa basebenzi ngesikhathi somsebenzi, kuqinisekisa ikhwalithi yemikhiqizo.

Imitjhini yokwenza iinkomitjhana yimitjhini ezenzakalelako eyenza iinkomitjhana zeplastiki ngeendlela ezifana nokubumba, ukusika, nokupakisha. Abafaki isitetjhi sokubetha.

Ipharamitha

Ngokuya ngolwazi lolu, ungakhetha umtjhini ofanele iindingo zakho. Nanyana yini oyikhethako, isiqhema sethu silapha ukukusiza bona wenze ukukhetha okuhle. Imitjhini yethu ihlanganisa umklamo okhangako kanye nentengo encintisanako, okwenza bona ithandwa makhasimende e-China nephasini loke.
