Icala elisezantsi lePP kukungafihli okuphantsi kwayo, oko kuyenza ilunge kakhulu kwizicelo ezifuna ukucaca okuphezulu okunje ngePET.

3. Polyvinyl Chloride (PVC)

I-PVC yindleko ephantsi kwaye kulula ukuyiqhubaiplastiki ye-thermoformingedla ngokusetyenziswa kwizinto zokwakha, izixhobo zonyango, kunye nokupakishwa. Iinzuzo zayo eziphambili ziquka:

• Amandla omatshini aphezulu: I-PVC inamandla omatshini kunye nokuqina, ilungele ukwenza iimveliso ezizinzileyo.
• Ukuxhathisa okuqinileyo kweekhemikhali: I-PVC iyaxhathisa kwiikhemikhali ezininzi kwaye ayibikho lula.
• Iplastiki ephezulu: I-PVC kulula ukuyiqhuba kwaye inokuguqulwa ngezongezo ezahlukeneyo ukulungisa iimpawu zayo.

Nangona kunjalo, i-downside ye-PVC kukusebenza kwayo okusingqongileyo, njengoko inokukhupha izinto ezinobungozi ngexesha lokucubungula kunye nokulahlwa, okwenza kube yimfuneko ukuyisebenzisa ngononophelo kwizicelo ezineemfuno eziphezulu zokusingqongileyo.

4. Ipolystyrene (PS)

I-PS yiplastiki ye-thermoforming ecacileyo kakhulu kunye nexabiso eliphantsi esetyenziswa kakhulu ekupakisheni ukutya, iimpahla zabathengi, kunye neemveliso zombane. Iinzuzo zayo eziphambili ziquka:

• Ukucaca okuphezulu: I-PS inokucaca okubalaseleyo, ivumela umboniso ocacileyo weemveliso.
• Kulula ukuyiqhuba: I-PS ilula kwi-thermoform kwaye inokubunjwa ngokukhawuleza ibe yimilo enzima.
• Iindleko eziphantsi: I-PS inexabiso eliphantsi lokuvelisa, okwenza ukuba ilungele imveliso enkulu.

Icala elisezantsi le-PS kukuqina kwayo okungalunganga, okwenza ukuba yophuke ngokulula kwaye ilunge kakhulu kwizicelo ezifuna ubunzima obuphezulu.

5. I-Polylactic Acid (PLA)

I-PLA yiplastiki enokubola ngokusebenza kakuhle kokusingqongileyo, isetyenziswa kakhulu ekupakishweni kokutya, izixhobo zonyango, kunye noshicilelo lwe-3D. Iinzuzo zayo eziphambili ziquka:

• Ukusebenza kakuhle kokusingqongileyo: I-PLA iyakwazi ukubola ngokupheleleyo kwaye iyahlangabezana neemfuno zokusingqongileyo.
• Ukucaca okuphezulu: I-PLA inokucaca kakuhle, ivumela ukubonakaliswa okucacileyo kweemveliso.
• Ukurisayikilisheka kwakhona: I-PLA inokuphinda isetyenziswe kwakhona, kucuthwe inkunkuma yobutyebi.

Icala eliphantsi le-PLA kukunganyangeki kobushushu, njengoko kuthanda ukukhubaza kumaqondo obushushu aphezulu, okwenza kube yimfuneko ukuyisebenzisa ngononophelo kwizicelo zobushushu obuphezulu.

Ungayikhetha njani eyona plastiki iThermoforming?

Ukukhetha eyona ilungileyoiplastiki ye-thermoformingifuna ukuthathela ingqalelo izinto ezahlukeneyo, kubandakanya iipropati zemathiriyeli, iimfuno zesicelo, kunye neendleko.

Kwizixhobo zonyango, ukumelana nobushushu obuphezulu kunye ne-biocompatibility kubalulekile, okwenza i-PP ibe yinto ekhethekileyo yokuchasana nokushisa kunye nokuchasana kweekhemikhali. Ukongeza, izixhobo zokwakha kunye nezicelo ezithile zemizi-mveliso zinokukhetha i-PVC ngenxa yamandla ayo omatshini aphezulu, nangona ingasebenzi kakuhle kokusingqongileyo.

Iindleko zibaluleke kakhulu kwimveliso enkulu. I-PP kunye ne-PS zihlala zikhethwa ngabavelisi abaninzi ngenxa yeendleko zabo zokuvelisa eziphantsi, kodwa kwezinye izicelo eziphezulu, i-PET eneendleko eziphezulu okanye i-PLA ehambelana nokusingqongileyo inokufaneleka ngakumbi. Ngokunyuka kolwazi lobutyebi kunye nokukhuselwa kokusingqongileyo, iimfuno zokusingqongileyo nazo ziba ngumlinganiselo obalulekileyo. I-PET enokuphinda isetyenziswe kunye ne-PLA enokubola ngokupheleleyo ineenzuzo ezibalulekileyo kwizicelo ezineemfuno eziphezulu zokusingqongileyo. Kwizicelo ezifuna ukukhanya okuphezulu kokubonisa iimveliso, i-PET kunye ne-PS zikhetho ezilungileyo, ngelixa izicelo zokumelana nokushisa zifaneleka ngakumbi kwi-PP.

Ngokukhetha izinto ezifanelekileyo, ukusebenza kwemveliso kunokulungiswa ukuhlangabezana neemfuno zezicelo ezahlukeneyo. Xa ukhetha iplastiki ye-thermoforming ingcono, kubalulekile ukuqwalasela iipropati zezinto eziphathekayo, imeko yesicelo, iindleko, kunye neemfuno zokusingqongileyo ngokubanzi ukuqinisekisa ukuba ukhetho olungcono lwenziwa, ukuphucula umgangatho wemveliso kunye nokhuphiswano lwemarike. Ndiyathemba ukuba eli nqaku likunceda ukuba uqonde iimpawu zeeplastiki ze-thermoforming ezahlukeneyo kwaye wenze ukhetho olunolwazi.
