Phakathi kokukhula okukhulu kwe-R&D kanye nokusungula izinto ezintsha kumapulasitiki obunjiniyela, ishidi le-polyethylene elinobukhulu obuphezulu (i-HDPE), ngenxa yokusebenza kwalo okuphezulu, liba yinto ekhethwayo emikhakheni yokwakha, ubunjiniyela bamakhemikhali, ukuvikelwa kwemvelo, kanye nemishini. Ngezinzuzo zalo ezivelele ezifana namandla aphezulu, ukumelana nokugqwala, kanye nokulula kokucutshungulwa,Ishidi le-HDPEichaze kabusha isimo sezinto zobunjiniyela.
I. Ukusebenza Okuphezulu
1. Amandla Aphezulu Nokumelana Nokugqwala
Ishidi le-HDPEinobuningi obungaba ngu-0.94-0.98 g/cm³ kanye nezinga eliphezulu lokukristali elingu-80%. Amaketanga ayo agcwele kakhulu ayenza ibe yizakhiwo ezinhle kakhulu zomshini. Amandla ayo okudonsa angama-≥20 MPa, amandla ayo okuguquguquka angama-≥24 MPa, futhi ukunwebeka kwayo lapho iphuka kungafinyelela ku-500%, okwenza ikwazi ukumelana nemithwalo ephezulu futhi ibonise ukumelana okunamandla kakhulu komthelela. Ngaphezu kwalokho, ishidi le-HDPE liyamelana nezixazululo ze-acidic ne-alkaline njenge-hydrochloric acid kanye ne-sodium hydroxide, kanye nezinyibilikisi eziphilayo, ekushiseni kwegumbi. kuma-60°C, ishidi le-HDPE ngeke liguquke, Lokhu kuyenza ibe yisinqumo esifanele sokusetshenziswa emikhakheni yokuvikela amakhemikhali kanye nemvelo.
2. Inobungani nemvelo kanye nokuphepha
I-HDPE ayinabo ubuthi futhi ayinaphunga, futhi idlulise izitifiketi eziningi zokuphepha kokudla kanye nokuphepha kokuvikela imvelo, okwenza kube yinto enobungani nemvelo. Kuyindlela ekhethwayo yokusika amashidi ezindaweni zokucubungula ukudla nasezindaweni zokuhlaba.
II. Izicelo Eziningi
1. Ukwakhiwa Kwezakhiwo Nekhaya
Ishidi le-HDPE lisebenzisa inqubo "yokubumba i-extrusion + ukuqopha ngokunemba", okuholela ekubunjweni kobuso obungenamthungo obuhlangana kahle neshidi ngokwalo, okuvimbela ukuqhekeka nokuqhekeka. Ukwengezwa kwe-masterbatch engamelana ne-UV kuvikela kakhulu ekulimaleni kwe-UV, kwandise impilo yayo yenkonzo yangaphandle. Ifanelekela izakhiwo zangaphandle kanye nokuhlobisa kwangaphakathi.
Amashidi esandwich e-HDPE anezingqimba ezimbili ayisinqumo esikhethwayo semishini yokudlala.
2. Imboni kanye Nezokuthutha
Amashidi e-HDPEzisetshenziswa embonini yamakhemikhali ezindongeni zamathangi namapayipi.
Emkhakheni wezokuthutha, zisetshenziswa njengemigqomo yeshelufu, ama-pallet, imigqomo yamaloli, imigqomo yamalahle, kanye nemigqomo ye-chute. Izakhiwo zazo ezilula, ezingagugi, ezingashayisani, kanye nokumuncwa kwamanzi aphansi zithuthukisa kakhulu ukusebenza kwazo kahle.
Omata bokuvikela umhlaba be-HDPE balula futhi abagqwali, okwenza basetshenziswe kabanzi ekugandayweni kwemigwaqo, ekuniseleni kwezolimo, nasezindaweni zokwakha.
Ngokuthuthuka kobuchwepheshe bepulasitiki yobunjiniyela, ukwakheka nokuthuthukiswa kwamashidi e-HDPE kuyaqhubeka kuthuthukiswa. Esikhathini esizayo, amashidi e-HDPE azothuthukela ekwenzeni kube lula, ukusebenza, kanye nokwenza ngezifiso ukuze kuhlangatshezwane nezidingo ezahlukahlukene. Ngokuhlanganiswa kwawo okuphelele kokusebenza kanye nokusetshenziswa, amashidi e-HDPE aba yinto eshintsha umdlalo emkhakheni wamapulasitiki amasha obunjiniyela.

Esikhathini esizayo,Amashidi e-HDPEizothuthukela ekwenzeni kube lula, ukusebenza, kanye nokwenza ngezifiso ukuze kuhlangatshezwane nezidingo ezahlukahlukene. Ngokuhlanganiswa kwayo okuphelele kokusebenza kanye nokusetshenziswa, amashidi e-HDPE aba yinto eshintsha umdlalo emkhakheni wepulasitiki entsha yobunjiniyela.
Kungakhathaliseki ukuthi kusekukhiqizweni, embonini, ekuvikelweni kwemvelo, ezindizayo, noma kweminye imikhakha, amashidi e-HDPE, ngokusebenziseka kwawo, ubungane bemvelo, kanye nokusungula izinto ezintsha, andisa amathuba empilo yanamuhla. Ukukhetha amashidi e-HDPE kusho ukukhetha ikusasa eliphumelelayo nelizinzile.
Isikhathi sokuthunyelwe: Okthoba-14-2025
