Cov yas feem ntau siv hauv thermoforming ntawm cov tshuab hlwv thiab lawv cov khoom
Tso lus
Thermoforming yog txheej txheem tsim khoom uas muaj cov cua sov ntawm cov ntawv yas kom txog thaum nws ncav cuag lub melting point thiab ces shaping nws mus rau hauv ib tug xav tau daim ntawv. Blister ntim yog ib qho ntawm cov kev siv nrov tshaj plaws ntawm thermoforming. Hauv kev ntim cov hlwv, cov khoom raug kaw ntawm lub hau yas molded thiab lub nraub qaum tsim kom haum rau cov khoom zoo.
Muaj ntau hom yas uas feem ntau siv rau hauv cov thermoforming ntawm cov tshuab blister. Qee yam uas feem ntau muaj xws li:
1. PVC (polyvinyl chloride): PVC yog cov khoom siv yas uas siv ntau tshaj plaws hauv kev ntim cov hlwv vim nws qhov yooj yim, ua haujlwm ntev thiab tus nqi qis. Nws kuj tseem tsim nyog rau kev luam ntawv thiab tuaj yeem ua xim yooj yim.
2. PET (polyethylene terephthalate): PET yog cov yas ntshiab, nruj thiab lub teeb yuag uas zoo tagnrho rau kev nthuav tawm cov khoom. Nws tseem yog recyclable, ua rau nws eco-phooj ywg.
3. PP (polypropylene): PP yog lub teeb yuag, ruaj thiab hloov tau yooj yim yas uas haum rau ntau yam kev siv. Nws kuj tseem tiv taus cua sov thiab tshuaj, ua rau nws zoo tagnrho rau kev siv hauv kev lag luam khoom noj.
4. PS (polystyrene): PS yog cov yas tsis khov thiab ntshiab uas feem ntau siv los ua cov khoom ntim khoom pov tseg, tais, thiab khob.
Txhua yam ntawm cov yas no muaj cov khoom tshwj xeeb uas ua rau nws tsim nyog rau kev siv sib txawv. Piv txwv li, PVC thiab PET yog qhov zoo rau kev nthuav tawm cov khoom vim lawv qhov tseeb thiab kev luam tawm zoo heev. PP yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau ua kom muaj zog thiab tiv taus cov tshuaj, thaum PS yog qhov zoo tshaj plaws rau kev ntim khoom pov tseg vim tias nws yog qhov hnyav thiab pheej yig.
Hauv kev xaus, thermoforming thev naus laus zis tau hloov pauv kev lag luam ntim khoom los ntawm kev tso cai rau kev tsim cov khoom ntim cov kev daws teeb meem. Nrog rau ntau yam ntawm cov yas muaj rau kev siv hauv thermoforming, cov tuam txhab tsim khoom tuaj yeem tsim cov ntim khoom raws li cov kev xav tau tshwj xeeb ntawm lawv cov neeg siv khoom.
