Ngaphasi kwe ikopi yeplastiki elahlwako nofana isivalo sekopi, kuvame ukuba nelebuli yokubuyisela kabutjha enomcibisholo, ukusuka ku-1 ukuya ku-7. Inomboro ezihlukileko zijamele izakhiwo ezihlukileko nokusetjenziswa kwezinto zeplastiki.
Akhe siqale:
“1′′ – I-PET (i-polyethylene terephthalate)
Ivame khulu emabhodleleni wamanzi wamaminerali kanye namabhodlela weenselo. Into le ijamelana nokutjhisa 70 begodu ingazaliswa ngamanzi wezinga lokutjhisa elijayelekileko ngesikhathi esifitjhani. Angeze yafaneleka ukusela iinselo ezine-asidi-base nofana amanzi anezinga lokutjhisa eliphezulu, begodu angeze yafaneleka ukuvezwa elangeni, ngaphandle kwalokho izokukhiqiza izinto ezinobuthi eziyingozi emzimbeni womuntu.
“2″ – HDPE (i-high density polyethylene). Isetjenziswa khulu emabhodleleni wemithi, emaphaketheni we-shawa gel, ayikafaneli iinkomitjhana zamanzi, njll.
“3″ – PVC (i-polyvinyl chloride). Ineplastiki ehle khulu nentengo ephasi, njeke isetjenziswa khulu. Ingamelana nokutjhisa ukuya ku-81 °C kwaphela, begodu kulula ukukhiqiza izinto ezimbi emazingeni womtjhiso aphezulu. Akusetjenziselwa ukupakisha ukudla.
“4′′ – LDPE (i-polyethylene ene-density encani). Ifilimu yokunamathelana nefilimu yeplastiki zoke zenziwe ngale nto. Ukujamelana nokutjhisa akunamandla, begodu ukuncibilika okutjhisako kuzokwenzeka lokha nakudlula i-110 °C.
“5′′ – PP (i-polypropylene). Inokuzinza okuhle kokutjhisa nokuvikela, begodu iphephile begodu ayilimazi emzimbeni womuntu. Umkhiqizo ungahlanzwa emazingeni womtjhiso angaphezu kwe-100, awutjhuguluki emazingeni womtjhiso ali-150 ngaphasi kwesenzo samandla wangaphandle, begodu awunamfutho emanzini abilako. Ibhodlela lebisi lesoya elivamileko, ibhodlela leyogathi, ibhodlela lesiphuzo sejuzi yezithelo, ibhokisi lokudla kwemini le-oveni ye-microwave. Indawo yokuncibilika iphezulu ukuya ku-167 °C. Ngilo kwaphela ibhokisi leplastiki elingafakwa ngaphakathi kwe-oveni ye-microwave begodu lingasetjenziswa godu ngemva kokuhlanzwa ngokutjheja. Kufanele kuqashelwe bona kwamanye amabhokisi wokudla we-microwave, umzimba webhokisi wenziwe nge-No. 5 PP, kodwana isembozo sebhokisi senziwe nge-No. 1 PE. Ngombana i-PE ayikghoni ukujamelana namazinga womtjhiso aphezulu, angeze yafakwa ngaphakathi kwe-oveni ye-microwave kanye nomzimba webhokisi.
“6″ – PS (i-polystyrene). Inkomitsho yeplastiki eyenziwe nge-PS iphuka khulu begodu ijamelana namazinga womtjhiso aphasi. Angeze yasetjenziswa emazingeni womtjhiso aphezulu, esidi enamandla kanye ne-alkali enamandla.
“7″ – PC nabanye. I-PC isetjenziselwa ukwenza amabhodlela webisi, iinkomitjhana, njll.
Ngalokho-ke, lokha nawusela iinselo ezitjhisako, kungcono ukutjheja amatshwayo asesembozweni sekopi, begodu uzame ukungasebenzisi ilogo ye-“PS” nofana iplastiki ye-“No. 6′′ ukwenza isembozo sekopi nezinto zokusebenza etafuleni.
Uchungechunge lwemitjhini yokutjhisa yekopi yeplastiki
HEY11Umtjhini we-Hydraulic Servo Plastic Cup Thermoforming
Isici somtjhini wokwenza ikopi
-Sebenzisa ihlelo lamanzi kanye nokulawula ithekhnoloji kagesi ukwelula i-servo. Mtjhini wezinga eliphezulu lentengo eyakhiwe ngokuya ngeemfuno zemakethe yamakhasimende.
-Umtjhini woke wokwenza ikopi yeplastiki ulawulwa yi-hydraulic kanye ne-servo, nge-inverter feeding, i-hydraulic driven system, i-servo stretching, lokhu kwenza bona ibe nokusebenza okuzinzileko begodu iphethe umkhiqizo onekhwalithi ephezulu.
HEY12Umtjhini wokwenza ikopi yeplastiki elahlekako ye-PLA
Umtjhini wokwenza ikopi Isibawo
Umtjhini wokwenza iinkomitjhana usetjenziselwa ukukhiqizwa kweentlobo ezihlukahlukeneko zeplastiki (iinkomitjhana zejeli, iinkomitjhana zesiphuzo, iinkomitjhini zephakheji, njll) ezinamashidi weplastiki atjhisako, afana ne-PP, PET, PE, PS, HIPS, PLA, njll.
I umtjhini wokwenza ikopi eyakhiwe ngokuzijamela yimitjhini ye-GTMSMAMRT inomzila wokukhiqiza ovuthiweko, amandla wokukhiqiza azinzileko, amakghono wekhwalithi ephezulu, isiqhema se-CNC R & D kanye nenethiwekhi yesevisi yangemuva kokuthengisa epheleleko, engakunikela isisombululo esisodwa.
