Xa kufikwa kuIiplastiki zeHDPE kunye nePP, kukho ukufana okuninzi okwenza kube lula ukudideka kwezi zinto zimbini kwiiprojekthi zakho zokuvelisa. Nangona kunjalo, ukukhetha phakathi kwe-HDPE kunye neplastiki ye-PP kunokukhokelela kumahluko obonakalayo kwimveliso yakho iyonke. Ngenxa yesi sizathu, kubalulekile ukuqonda umahluko phakathi kwe-HDPE kunye ne-PP kunye neenzuzo ezisisiseko ezinokubakho kwiprojekthi elandelayo yeshishini lakho.

Iimpawu zeplastiki zePP kunye neHDPE

Sicinga ngaloo nto, sihlola amandla azo zombini ezi zinto kwaye sibonisa umahluko wazo ukuze sikuncede ukhethe ezona zinto zilungele iimfuno zeshishini lakho. Jonga oku:

Ibhotile Yamanzi yeHDPE

Izixhobo zeHDPEimele iHigh Density Polyethylene kwaye yiplastiki eguquguqukayo eyaziwa ngeenzuzo zayo ezikhethekileyo. Ngenxa yamandla agqithisileyo ale nto, iHDPE isetyenziswa kakhulu ekwenzeni izikhongozeli ezifana nobisi kunye neejagi, apho ijagi engama-60-gram inokugcina ngokufanelekileyo ngaphezulu kwegaloni yolwelo ngaphandle kokuphazamisa imo yayo yokuqala.

Nangona kunjalo, i-HDPE inokuhlala iguquguquka. Umzekelo, cinga ngeengxowa zeplastiki. Ihlala ixesha elide, imelana nemozulu, kwaye iyakwazi ukumelana nobunzima, i-HDPE lukhetho olufanelekileyo kwabo bafuna iplastiki enokumelana nezinto ezahlukeneyo zoxinzelelo ngelixa igcina amandla ayo, nokuba iqinile okanye iguquguquka.

I-HDPE yaziwa ngokuchasana kwayo nokubola, ukubola kunye nokugqwala, yiyo loo nto isetyenziswa kakhulu kwiindlela ezahlukeneyo zokwakha kunye nokucoca. Ngaphezu koko, inokubunjwa ibe yiyo nayiphi na imilo ngelixa igcina ubunzima bayo bulula, nto leyo eyenza ukuba ibe lukhetho olufanelekileyo xa kuthelekiswa nezinye iintlobo zeplastiki.

Iingenelo zeplastiki yePP
Iteyiphu yeplastiki yePolypropylene

I-PP imele iplastiki ye-polypropylene kwaye yiplastiki eyaziwa kakhulu ngendalo yayo ye-semi-crystalline, enokwakheka ngokulula ngenxa yokunyibilika okuncinci kwezinto. I-Polypropylene ifanelekile ekubumbeni ngenaliti – kodwa ayikokuphela kwayo ukusetyenziswa.

Iplastiki yepolypropylene ikho kuyo yonke indawo, ukusuka kwiintambo ukuya kwiikhaphethi kunye neempahla. Yinto yorhwebo efikelelekayo ebonelela amashishini ngokumelana okukhulu kweekhemikhali kwiintlobo ngeentlobo zeziseko kunye neeasidi. Oku kuthetha ukuba ukubaIvalvu yePP kunye nezinto zokufakelwaukuba kufuneka icocwe, isenokungamelani nezicoci zeekhemikhali ixesha elide kuneeplastiki ezifanayo – nto leyo enika ukucoca nokugcinwa okulula.

Kwakhona, i-PP yinto elula xa ithelekiswa nezinye iintlobo zeplastiki. Oku kwenza ukuba ibe yindawo efanelekileyo yokutshintsha iintlobo ngeentlobo zezicelo zorhwebo, nokuba amashishini afuna iiplastiki zokwenza izikhongozeli eziphinda zisetyenziswe okanye amalaphu.

Ngaba i-HDPE okanye i-PP zifanelekile kwishishini lam?
Zombini iplastiki ye-HDPE kunye neplastiki ye-PP zinezibonelelo ezifanayo. Ukongeza ekubeni zithambile kakhulu, zikwamelana nokuchaphazeleka, nto leyo ethetha ukuba akukho mfuneko yokukhathazeka ngamandla xa usebenza ngezi plastiki. Ngaphezu koko, zombini i-HDPE kunye ne-PP zithathwa njengezimelana nobushushu kwaye azinabungozi ebantwini. Oku kungaba yenye into ekufuneka iqwalaselwe ukuba iplastiki iza kusetyenziswa kwizinto ezifana nezikhongozeli zokutya neziselo.

Okokugqibela, nganye kwezi plastiki ingaphinda isetyenziswe, nto leyo enokuba luncedo kumashishini anobuhlobo nokusingqongileyo ajongene nokuvelisa izinto ezininzi ezisetyenziswa okwethutyana (umz. izikhongozeli zokutya, imiqondiso).

Okokugqibela, ngaphambi kokuba benze isigqibo sokugqibela, amashishini kufuneka acinge ngeenzuzo ezahlukeneyo zokusebenzisa i-HDPE kunye ne-PP. Ukwenza njalo kuqinisekisa ukuba basebenzisa uhlahlo lwabiwo-mali lwabo xa betyala imali kwiintlobo ezithile zeplastiki.
