I-Polyethylene Rollers Kwiimpawu kunye neenzuzo kwi-belt conveyor

Iimpawu kunye neenzuzo zei-ultra-high molecular weight polyethylene rollers

I-roller iyinxalenye ebalulekileyo kunye nenxalenye esengozini yezixhobo zokuhambisa, kwaye umgangatho wayo unquma ngokuthe ngqo ubomi benkonzo yesixhobo sokuhambisa kunye nokuba buninzi bamandla asetyenziswayo.Iirola zezixhobo zokuhambisaokwangoku esetyenziswa kwilizwe lethu ubukhulu becala zisebenzisa iirola zentsimbi.Xa kuthelekiswa ne-roller yeemveliso ezifanayo zangaphandle, kukho iintsilelo ezifana nobomi obufutshane benkonzo, i-coefficient enkulu yokumelana nokusebenza, kunye nobunzima obukhulu bee-roller.Ngaphezu koko, iimveliso ze-roller zetsimbi zifanelekile kuphela kwizihlandlo zokuvelisa ngokubanzi.Kwimigodi eneemfuno eziphezulu zengxolo kunye nombane ongatshintshiyo, izityalo ezidliwayo ezidliwayo, iinkampani zeekhemikhali, kunye neminye imisebenzi ekhethekileyo, ubude besicelo ziinyanga ezi-6, ezimfutshane Inyanga enye izise izithintelo ezinkulu kunye nemingcipheko yokuvelisa izixhobo zokuhambisa.Iingozi zokhuseleko zenzeke ngokuphindaphindiweyo, ezibangele ilahleko enkulu kunye nokusetyenziswa kwamandla aphezulu.Ngenxa yobuninzi bee-roller ezisetyenzisiweyo kunye nokusetyenziswa kwamandla amakhulu, ukuguqulwa kwee-roller zentsimbi zendabuko zitshisa amashiya.Ngokusekwe koku, siphuhlise i-ultra-high molecular weight polyethylene rollers esekwe kwimo yezakhono zasekhaya nezangaphandle, ngokwesiseko se-roller zetsimbi ngokubanzi, kunye nokuveliswa kwezinto ezintsha kwizakhono, ubume, kunye nezixhobo zokusebenza.
1. I-Roller yedatha ye-UHMWPE
I-polyethylene ene-molecular weight more than 1.5 million ibizwa ngokuba yi "UHMW-PE", esetyenziswa njengeplastiki yobunjineli ngenxa yemisebenzi yayo emihle yomzimba.Xa sikhetha imathiriyeli ekrwada, siqala siqwalasele le misebenzi ibalaseleyo yesicelo:
(1) Ukumelana nokunxiba Ukumelana nokunxitywa kwe-UHMWPE kuqala phakathi kweeplastiki kwaye yodlula iintsimbi ezithile.Ukuxhathisa okuphakamileyo okunjalo kwenza kube nzima ukuvavanya ukuxhathisa kwayo ngeendlela zokuvavanya ukunxiba kweplastiki ngokubanzi.Ngoko ke, ukugqoka umdaka kukhethiweyo.Kwizixhobo zokuvavanya, ukuxhathisa ukunxiba kuhambelana nobunzima bemolekyuli, njengoko ubunzima bemolekyuli bukhula, ukuxhathisa ukunxiba kuya kuba ngcono;
(2) Ukuchaswa kwempembelelo kunye nefuthe lokufunxa amandla.Kunzima ukuqhekeza kunye nomonakalo ngeendlela zokuvavanya impembelelo jikelele.Amandla ayo eempembelelo ayanda ngokunyuka kobunzima be-molecular, ukufikelela kumlinganiselo ophezulu xa ubunzima be-molecular buyi-1.5 yezigidi, kwaye ke iyaqhubeka ikhula kunye nesisindo se-molecular.Kwaye kancinci kancinci.Ukongeza, inobunzima obuphezulu bomphezulu emva kwempembelelo ephindaphindiweyo;inempembelelo egqwesileyo yokufunxa amandla, enexabiso eliphezulu lokufunxa amandla phakathi kwazo zonke iimodeli zeplastiki, ngoko inengxolo elungileyo yokuthomalalisa kunye nokunciphisa ingxolo okugqwesileyo;
(3) Ukuzithambisa kwe-UHMWPE inomba wokungquzulana ophantsi kakhulu (0.05～0.11), ngoko ke igqwesile ekuzithambiseni.Ukususela kwiThebhile 1, kunokubonwa ukuba into ephikisanayo ingaphantsi kweyona nto ibhetele yokuzithambisa i-polytetrafluoroethylene (PTEE), ngoko idunyiswa kwinkalo yenzululwazi yengxabano njengento ephethe imisebenzi eyinkunzi eyinkunzi;
(4) Ukumelana neekhemikhali.Inokumelana nekhemikhali ebalaseleyo.Ukongeza kwi-acids oxidizing eyomeleleyo, inokumelana nemithombo yeendaba ezonakalisayo (ezifana ne-acids, alkalis, kunye neetyuwa) kunye nemidiya yendalo kwiqondo lobushushu elithile kunye nobunzulu.Isinyibilikisi seti singaphandle).Intywiliselwa kwiintlobo ezingama-80 ze-solvents eziphilayo kwi-20 ° C kunye ne-80 ° C iintsuku ezingama-30 ngaphandle kokubonakala okungaqhelekanga, kunye neminye imisebenzi yomzimba phantse ingatshintshi;
(5) I-UHMWPE engabambekiyo inamandla obhengezo abuthathaka kakhulu, kwaye isakhono sayo sokuchasa ukuncamathela sikwindawo yesibini kuphela kwi-PTEE, eyona nto ingancangathi kakhulu kwiplastiki, ngoko ke imbonakalo yemveliso akulula ukubambelela kuyo. izixhobo.Ukongeza, i-UHMWPE nayo ineempawu zokumelana nobushushu obuphantsi (ukwenza i-roller isebenze kwinqanaba elikhulu), i-hygienic, i-non-toxic, kunye ne-hydrophobic (i-roller ayilula ukufunxa amanzi kunye nokukhubazeka).
Ukungaphumeleli kwe-UHMWPE: Xa kuthelekiswa nezinyithi kunye nezinye iiplastiki zobunjineli, ukumelana nobushushu, kunye nobunzima buphantsi, kodwa bunokuphuculwa "ngokuzalisa" kunye "nokudibanisa".
2. Ukuphakama kwe-ultra-high molecular weight polyethyleneukuhambisa idler roller
(1) Ngenxa yokuba i-coefficient yokumelana nokusebenza kunye ne-inertia ejikelezayo iyancitshiswa kakhulu, umsebenzi we-roller uba buthathaka kwaye uzinzile.I-Ultra-high molecular weight polyethylene inempembelelo entle ekufunxeni kwamandla kunye nokuthomalalisa, enokunciphisa ngokufanelekileyo ingxolo yokusebenza kwaye yenza ukuba izixhobo zokuhambisa zigqibe umgama omde, umthamo omkhulu, kunye nokusebenza ngesantya esiphezulu.Nangona kunjalo, ngokuqwalasela iintsilelo zamandla aphantsi e-polyethylene izinto eziluhlaza, kuyimfuneko ukudlula izibalo ezizinzileyo kunye novavanyo.
(2) Ngenxa yokuba i-ultra-high molecular weight polyethylene roller inenkangeleko yokungabambeleli, i-rust, kunye ne-self-lubricating, inokhuseleko olungcono lokuthutha, nangona i-roller yonakalisiwe kwaye ayiqengqeleki, ayiyi kuqengqeleka. yonakele.Ibhanti lokuhambisaakukho lula ukunxiba kunye nobomi benkonzo yebhanti yokuhambisa,ukuhambisa roller
