Ipuleti le-UHMWPE lamukela uhlobo lwe-Ziegler olusebenza kahle kakhulu lwe-catalyst low-pressure synthesis indlela futhi lilawulwa ngaphezu kwezigidi ezingu-1.5 kuya kwezingu-3 njengoba kudingeka.Uma kubhekwa ukuwohloka okushisayo kwama-molecule ngesikhathi sokucubungula, i-polyethylene ephezulu-density ene-viscosity isilinganiso samangqamuzana angaphezu kwezigidi ezingu-1.7 ingacutshungulwa ibe yimikhiqizo ehlukahlukene ukuze ibe nokusebenza okuphezulu kakhulu.

1. Ukumelana nokugqokwa okuphezulu: Ipuleti le-UHMWPE linokumelana kangcono nokugqokwa phakathi kwawo wonke amapulasitiki obunjiniyela bamanje futhi lidonsa amehlo kakhudlwana.Lapho i-molecular iphakama, insimbi imelana kakhulu, ngisho nangaphezu kwezinto eziningi zensimbi (njenge-carbon steel, insimbi engagqwali, ithusi, njll.).Isibonelo, amapayipi e-UHMW-PE anokuphila kwesevisi izikhathi ezingu-4-6 zamapayipi ensimbi ngaphansi kwezimo zokugqwala okuqinile nokugqoka okuphezulu, futhi andise ukusebenza kahle kokudlulisela ngo-20%.Ibonisa ngokugcwele ukuphakama "kokonga amandla, ukuvikelwa kwemvelo, umnotho nokusebenza kahle okuphezulu".
2. Ukumelana nokugqwala: Ayigqwali ku-lye futhi ingasetshenziswa ku-hydrochloric acid egxilile ku-80°C.Inokusebenza okuzinzile ku-75% ye-concentrated sulfuric acid kanye ne-20% ye-nitric acid.Iphinde izinze emanzini olwandle kanye nezihlanzi eziwuketshezi.
3. I-coefficient ephansi kakhulu yokungqubuzana: I-coefficient yokungqubuzana okumile ngu-0.07, futhi inezici ezinhle zokuzithambisa.Kuyi-bearing, i-bushing, i-sliding block kanye ne-lining material ekahle.Ukusebenzisa ipuleti le-UHMWPE njengengxenye yokungqubuzana kwezisetshenziswa akukwazi nje ukukhulisa impilo engagugi, kodwa futhi kuthola imiphumela yokonga amandla.
4. Ukumelana nomthelela: Ukumelana nomthelela kuqala phakathi kwamapulasitiki.Kungakhathaliseki ukuthi amandla angaphandle anamandla noma ukushintshashintsha kwengcindezi yangaphakathi, kunzima ukuqhekeka.Amandla ayo omthelela aphindwe ka-10 kunayiloni 66, izikhathi ezingu-20 kune-polyvinyl chloride, futhi izikhathi ezingu-8 kune-polytetrafluoroethylene.Ikakhulukazi ezindaweni zokushisa eziphansi, amandla awo omthelela afinyelela inani eliphakeme, futhi ukuguquguquka kwawo kunganikeza izinhlelo zokuhamba eziphephile kakhulu, isiqinisekiso esithembekile.
