Kungani i-HDPE inamandla kangaka?
Utshelwa ukuthi uthembele ku-HDPE, kodwa ibukeka njengepulasitiki nje. Kunzima ukukholwa ukuthi ingaba namandla njengezinto zendabuko, okwenza ungabaze ukuyichaza ngemisebenzi ebalulekile.
I-HDPE inamandla kakhulu ngenxa yesakhiwo sayo sama-molecule esiqinile nesiqondile. Ngesikhathi sokukhiqiza, amaketanga amade e-polyethylene akhiwa ngamagatsha ambalwa kakhulu, okuwavumela ukuthi ahlanganiswe ndawonye. Lokhu kudala izinto eziqinile, ezikristalu eziqinile futhi eziqinile kakhulu.
Igama elithi “High-Density Polyethylene” likutshela konke. “High-Density” liyimfihlo yamandla alo. Cabanga ngakho njengokupakisha ipotimende. Uma ufaka nje izingubo, kunendawo eningi engenalutho. Kodwa uma uzigoqa kahle, ungangena okuningi. Ama-molecule ku-HDPE afana nezingubo ezigoqwe kahle; ahlanganiswa ndawonye ngokuqinile. Lokhuisakhiwo esiqinilekwenza kube nzima kakhulu ukuthi amakhemikhali angene noma ukuthi imivimbo ibangele ukuqhekeka. Ngokuphambene nalokho, i-Low-Density Polyethylene (LDPE) inama-molecule ahlanganisiwe afana nezingubo ezigoqekile—awakwazi ukupakisha kahle, ngakho-ke izinto zithambile futhi zibuthakathaka. Njengomkhiqizi, ngiyazi ukuthi ikhwalithi yepayipi lokugcina inqunywa yikhwalithi yalesi sakhiwo sama-molecule ku-resin eluhlaza. Yingakho sithola kuphelai-resin ye-PE100 engeyona i-virgin, esebenza kahle kakhulu.

Iyini inkinga ye-HDPE?
Uzwa ngazo zonke izinzuzo ze-HDPE, kodwa uyazi ukuthi akukho okubalulekile okuphelele. Ukunganaki ubuthakathaka bayo kungaholela ekwehlulekeni emkhakheni, okuyingozi ongenakukwazi ukuyikhokhela.
Izinkinga ezinkulu ze-HDPE ukuthi isengozini yokuwohloka kwe-UV uma ingavikelwe, izinga lokushisa elilinganiselwe uma liqhathaniswa nezinsimbi, kanye nokwanda okuphezulu kokushisa. Ukuhlanganiswa okufanele kudinga imishini ekhethekile kanye nabasebenzi abaqeqeshiwe.
Ngikholelwa ekuthembekeni ngemikhawulo yemikhiqizo yami. Kusiza amakhasimende ethu ukuthi enze izinqumo ezingcono. Okokuqala, imisebe ye-UV yelanga ingenza i-HDPE ibe buthaka. Sixazulula lokhu ngokuphelele ngokufaka cishe u-2% wekhabhoni omnyama kumapayipi ethu okucindezela, yingakho emnyama.i-carbon black isebenza njengesiqinisi se-UV esinamandla. Okwesibili, i-HDPE ayilungele amanzi ashisayo. Isebenza kahle kakhulu ngaphansi kuka-60°C (140°F). Kuketshezi lwezimboni olushisa kakhulu, ezinye izinto zingcono. Okwesithathu, iyakhula futhi inciphe ngokushisa okungaphezu kwensimbi. Kumapayipi agqitshwe, inhlabathi iyibamba endaweni yayo. Kumapayipi angaphezulu komhlabathi, umklamo kumele ubhekele lokhu kunyakaza. Okokugcina, awukwazi ukuyinamathelisa noma ukuyibopha. Udingaimishini efanele yokuhlanganisa ukushisaNakuba lokhu kudinga ukutshalwa kwezimali kokuqala kumathuluzi nokuqeqeshwa, futhi kunamandla amakhulu, njengoba kuqinisekisa uhlelo olungavuzi lutho oluphelele.
Ukuphatha Ukulinganiselwa kwe-HDPE

Ingabe i-HDPE inamandla kunepulasitiki?
Igama elithi “ipulasitiki” livame ukuzwakala libuthakathaka noma lingasetshenziswa. Ukhathazeka ngokuthi ukusebenzisa ipayipi le-HDPE kuyindlela yokunciphisa amandla nokuphila isikhathi eside. Lokhu kungaqondi kahle kungakwenza ukhethe izinto ezisindayo nezibiza kakhulu.
Lokhu kuyindida evamile, ngoba i-HDPEisuhlobo lwepulasitiki. Kodwa-ke, ipulasitiki yezinga lobunjiniyela enamandla kakhulu kunepulasitiki “yenjongo evamile.” Uma iqhathaniswa nezinto ezisetshenziselwa ukupakisha noma izinto zasekhaya, i-HDPE iqine kakhulu, ihlala isikhathi eside, futhi yenzelwe ukusetshenziswa okunzima.
Ukuthi “ipulasitiki” kufana nokuthi “insimbi.” Ithini le-aluminium kanye nogongolo lwensimbi kokubili kuyinsimbi, kodwa kunamandla ahlukene ngokuphelele kanye nokusetshenziswa. Kuyafana ngamapulasitiki. Ipulasitiki esebhodleleni lamanzi elilahlwayo (i-PET) ayifani nepulasitiki esebhampeleni lemoto yakho (ngokuvamile ingxube ye-Polypropylene), engafani nepulasitiki esebhodleleni elikhulu lamanzi elinomfutho ophezulu (i-HDPE). I-HDPE iwela esigabeni esithi “i-thermoplastics yobunjiniyela"Lezi izinto eziklanyelwe ngqo ukubhekana nokucindezeleka komshini, umfutho ophezulu, kanye nezimo ezinzima isikhathi eside kakhulu. Uma umphathi wokuthenga njengo-Arief ecacisa ipayipi, akagcini nje ngokuthenga "ipulasitiki"; ukhetha izinto ezakhiwe kahle kakhulu ezinezici zokusebenza eziqinisekisiwe ezincintisana noma ezidlula izinto zendabuko ezifana nokhonkolo noma insimbi ethambile ezisetshenziswayo eziningi.
