Iimfuno ezahlukeneyo zeentlobo ezahlukeneyo zokucubungula iipayipi ze-PE
Nditsalele umnxeba. yenziwe yi-polymerization ye-monomer ethylene, ngenxa yeemeko ezahlukeneyo ze-polymerization reaction ezifana noxinzelelo kunye nobushushu ngexesha le-polymerization, ubuninzi obahlukeneyo be-resin bungafumaneka, kwaye ngaloo ndlela kukho i-polyethylene enoxinano oluphezulu, i-polyethylene enoxinano oluphakathi kunye ne-polyethylene enoxinano oluphantsi. Ekucutshungulweni kweentlobo ezahlukeneyo zepayipi ye-PE, ngokweemeko ezahlukeneyo zokusetyenziswa kwayo, ukukhethwa kwamanqanaba ahlukeneyo e-resin, ngelixa iimfuno ze-extruder kunye ne-mold nazo zahlukile.
(1) Uqhagamshelo oluthembekileyo: inkqubo yemibhobho ye-polyethylene iqhagamshelwe yi-electro-thermal fusion, kwaye amandla eejoyinti aphezulu kunamandla omzimba wemibhobho.
(2) Ukumelana kakuhle nempembelelo kubushushu obuphantsi: ubushushu obuphantsi bokubhitya kwe-polyethylene buphantsi kakhulu, kwaye ingasetyenziswa kubushushu obuphakathi kwe -60-60℃. Ngexesha lokwakhiwa kwebusika, akukho kubhitya kwepayipi okuya kwenzeka ngenxa yokumelana kakuhle nempembelelo yento.
(3) Ukumelana kakuhle nokuqhekeka koxinzelelo: I-HDPE ayinakuqhekeka kakhulu, inamandla aphezulu okucheba kwaye inokumelana okuhle nokukrwela, kwaye inokumelana okubalaseleyo nokuqhekeka koxinzelelo lokusingqongileyo.
(4) Ukumelana kakuhle neekhemikhali: Umbhobho weHdpeIikhemikhali azikwazi ukumelana nokugqwala ngenxa yeentlobo ngeentlobo zeekhemikhali, kwaye iikhemikhali ezikhoyo emhlabeni aziyi kubangela ukuwohloka kwemibhobho. I-Polyethylene sisithinteli sombane, ngoko ke ayizukubola, ayizukugqwala okanye ibole nge-electrochemical; ukongeza, ayizukukhuthaza ukukhula kwe-algae.
(5) Ukumelana nokwaluphala kunye nexesha elide lokusebenza: iipayipi ze-polyethylene eziqulathe i-2-2.5% ye-carbon black esasazwe ngokulinganayo ziyakwazi ukugcinwa okanye ukusetyenziswa ngaphandle emoyeni ovulekileyo iminyaka engama-50 ngaphandle kokonakaliswa yimitha ye-ultraviolet.
(6) Ukumelana nokukrweleka okuhle: uvavanyo oluthelekisayo lokuxhathisa ukukrweleka kombhobho we-HDPE kunye nombhobho wentsimbi lubonisa ukuba ukumelana nokukrweleka kombhobho we-HDPE kuphindwe kane kunoko kombhobho wentsimbi. Kwicandelo lokuthuthwa kodaka, xa kuthelekiswa nombhobho wentsimbi, umbhobho we-HDPE unokumelana nokukrweleka okungcono, oko kuthetha ukubaI-T Hdpe Umbhobho unexesha elide lenkonzo kwaye ungcono kakhulu.
(7) ukuguquguquka okuhle: ukuguquguquka kombhobho we-HDPE kwenza kube lula ukugoba, ubunjineli bungatshintshwa ngokutshintsha indlela yombhobho ukuze kudlule imiqobo, kwiimeko ezininzi, ukuguquguquka kombhobho kunokunciphisa ubungakanani be-piIzixhobo zePe kwaye kuncitshiswe iindleko zokufakela.
(8) ukumelana okuphantsi kokuhamba kwamanzi: Umbhobho we-HDPE unomphezulu wangaphakathi ogudileyo, i-coefficient yayo yeManning yi-0.009. ukusebenza okugudileyo kunye neempawu zokunganamatheli ukuqinisekisa ukuba umbhobho we-HDPE unomthamo ophezulu wokuhambisa kunembhobho yendabuko, kodwa ikwanciphisa ukulahleka koxinzelelo lombhobho kunye nokusetyenziswa kwamandla kokuhambisa amanzi.
(9) Ukuphathwa okulula: Umbhobho we-HDPE ukhaphukhaphu kunembhobho yesamente, umbhobho we-galvanized kunye nombhobho wentsimbi, kulula ukuwuphatha nokuwufaka, kuncinci abasebenzi kunye neemfuno zezixhobo, oko kuthetha ukuba iindleko zokufakela iprojekthi zinciphile kakhulu.
(10) Iindlela ezahlukeneyo zokwakha: Umbhobho we-HDPE uneendlela ezahlukeneyo zokwakha, ukongeza kwiindlela zemveli zokumba zingasetyenziswa ekwakheni, kodwa kukwakho neendlela ezahlukeneyo zokumba ezingezizo ezokumba ezifana nokugquma imibhobho, ukubhola ngendlela ethile, ukugquma imibhobho, ukuqhekeka kunye nezinye iindlela zokwakha, olukhetho olufanelekileyo kwezinye iindawo ezingavumeli ukugrumba, ngoko ke umbhobho we-HDPE unoluhlu olubanzi lwezicelo.
