Ukusuka kwimbono yengqiqo:
I-PC (iPolycarbonate): Le yiplastiki engenambala, ecacileyo ebukekayo kwaye imtyibilizi. Ngenxa yobume bayo obungenatyhefu kunye nevumba, kunye neempawu zayo ezibalaseleyo zokuthintela i-UV kunye nokugcina ukufuma, iPC inoluhlu olubanzi lobushushu. Ihlala ingenakuphulwa kwi -180 ° C kwaye ingasetyenziselwa ixesha elide kwi-130 ° C, okwenza kube yinto efanelekileyo yokupakisha ukutya.
I-PET (iPolyethylene Terephthalate) : Le yimathiriyeli ekhazimle kakhulu, ayinambala, kwaye iyabonakala kwaye iqine kakhulu. Inenkangeleko efana neglasi, ayinavumba, ayinancasa, kwaye ayinayo ityhefu. Iyatsha, ivelisa ilangatye elityheli elinomphetho oluhlaza okwesibhakabhaka xa litshisiwe, kwaye ineempawu ezilungileyo zokuthintela igesi.
Ngokwembono yeempawu kunye nezicelo:
PC: Inempembelelo entle yokuchasa kwaye kulula ukuyibumba, ukuyivumela ukuba iveliswe kwiibhotile, iingqayi, kunye neemilo zesikhongozeli ezahlukeneyo zokupakisha ulwelo olufana neziselo, utywala kunye nobisi. I-drawback ephambili yePC kukuchaphazeleka kwayo kuxinzelelo lokuqhekeka. Ukunciphisa oku ngexesha lemveliso, izinto ezicocekileyo eziphezulu zikhethiweyo, kwaye iimeko ezahlukeneyo zokucubungula zilawulwa ngokungqongqo. Ukongezelela, ukusebenzisa i-resins kunye noxinzelelo oluphantsi lwangaphakathi, olufana nexabiso elincinci le-polyolefins, i-nylon, okanye i-polyester yokuxuba inyibilika, inokuphucula kakhulu ukuchasana kwayo noxinzelelo lokuqhaqha kunye nokufunxa kwamanzi.
I-PET: Inomlinganiselo ophantsi wokwandiswa kunye nesantya esiphantsi sokubumba i-shrinkage ye-0.2% kuphela, enye yeshumi ye-polyolefins kwaye iphantsi kune-PVC kunye ne-nylon, okubangelwa imilinganiselo ezinzileyo yeemveliso. Amandla ayo omatshini athathwa njengeyona nto ibhetele, kunye neempawu zokwandisa ezifana ne-aluminium. Amandla okuqina kweefilimu zawo aphindwe alithoba e-polyethylene kwaye aphindwe kathathu i-polycarbonate kunye nenylon, ngelixa amandla ayo empembelelo aphindwe kathathu ukuya kahlanu kwiifilimu eziqhelekileyo. Ukongeza, iifilimu zayo zinezithintelo zokufuma kunye neempawu zokugcina ivumba. Nangona kunjalo, nangona ezi nzuzo, iifilimu ze-polyester zibiza kakhulu, kunzima ukufudumeza itywina, kwaye zithandwa ngumbane ongatshintshiyo, kungoko zingafane zisetyenziswe zodwa; zihlala zidityanisiwe kunye ne-resin ezinokutywinwa kobushushu obungcono ukwenza iifilimu ezidibeneyo.
Ke ngoko, iibhotile ze-PET eziveliswe kusetyenziswa inkqubo yokubumba i-biaxial stretching blowue zinokusebenzisa ngokupheleleyo iimpawu ze-PET, zibonelela ngokucace kakuhle, isicwebezelisi somgangatho ophezulu, kunye nenkangeleko efana neglasi, izenza ezona bhotile zifanelekileyo zokutshintsha iibhotile zeglasi.
