I-PE Conical Twin Screw Barrel

Le PE conical twin screw barrel yenziwe ngentsimbi ye38CrMoAla. Imathiriyeli ekrwada ibalulekile ekujikeni ukusebenza, kwaye sikhetha amandla aphezulu kunye nentsimbi engagugiyo kubavelisi bentsimbi abaziwayo baseTshayina abahlangabezana nemigangatho yesizwe (GB/T 3077).

INanhaiya's PE conical twin screw barrels ngokwesiqhelo iveliswa kwiintsimbi ezikumgangatho ophezulu wealloy, ezinje nge38CrMoAlA, ezibonelela ngokugqwesileyo ukunxiba kunye nokuxhathisa umhlwa kunye namandla aphezulu obushushu. I-nitriding kunye nezinye iinkqubo zongeza ubulukhuni bomphezulu kunye nokunganyangeki, ukwandisa ubomi benkonzo. I-conical twin-screw barrel design ikhuthaza iimpawu zokuhamba ezizinzileyo. Ngokuqinisekisa ukutya okuhambelanayo kunye noxinzelelo kuyo yonke inkqubo ye-extrusion, oku kunceda ukunciphisa ukuhamba okungaqhelekanga okunje ngokuguquguquka okanye ukubetha, ukunciphisa ukunxitywa kwezixhobo kunye nokwandisa ubomi benkonzo yombhobho.

INanhaiya's PE conical twin screw barrels ziye zadlula kwi-R&D ezininzi kunye nophuculo kwaye ngoku zidityaniswe kwimigca yokuvelisa abavelisi abahlukeneyo, ukuphumeza ukusebenza komgangatho. Sinikezela ngewaranti yeminyaka eyi-1-2, kuxhomekeke kumlinganiselo othile wokongezwa kwezinto. Imigqomo ye-Nanhaiya ingena kwinkqubo ye-nitriding, kunye ne-2mm engqindilili ye-nickel-tungsten alloy alloy spray-welded kwiindawo ezithandwa kakhulu. Oku kwandisa ukuqina komphezulu we-barrel ukusuka kwi-HRC55-60 ukuya ngaphezulu kwe-HRC65, ukunyusa ukuxhathisa ukunxiba ngamaxesha angama-2-4.

Uphawu kunye nesicelo

I-PE conical twin screw extruders ibonakalisa uyilo olujikajikayo (izikrufu ezibini zijikeleza kumacala achaseneyo). Oku kudala isithuba esincinci esidibanisayo, sivelisa amandla aqinileyo okucheba (ukukhuthaza ukwenziwa kweplastiki ye-PE) ngelixa kukwavumela ukuba iinqwelomoya zicoceke (ukunciphisa intsalela yezinto kunye nokuthintela ukuthotywa).

INanhaiya's PE conical twin screw extruders ibonakalisa indawo encinci yokucocwa phakathi kweenqwelomoya ezijijwayo kunye nodonga lomgqomo (ngokuqhelekileyo yi-0.1-0.3mm). Idityaniswe neziphumo zokucheba kunye ne-extrusion eyenziwe zizikrufu ezijikelezayo, zinyibilika ngokukhawuleza iigranules ze-PE kwaye zisasaze ngokulinganayo izongezo (ezifana ne-antioxidants kunye ne-colorants). Uyilo lwe-screw lubonelela ngesithuba se-vents kunye nezihluzo ezinyibilikayo, ezibavumela ukuba basebenze kunye ne-barrel's exhaust system ukususa ukufuma kunye ne-low-molecular-weight-volatiles kwi-PE melt, ukuqinisekisa imveliso engenamaqamza. Izihluzi zobukhulu obahlukeneyo bee pore zinokusetyenziselwa ukuhluza ubumdaka kunye nokuphucula ubunyulu bemveliso.

I-PE conical twin screw barrel iyahambelana neentlobo ze-PE izinto ezibonakalayo: i-LDPE (i-polyethylene ephantsi-i-low-density), i-HDPE (i-polyethylene ephezulu), i-LLDPE (i-linear low-density polyethylene), kunye nezinye iintlobo ze-PE. Ngokuhlengahlengisa isantya se-screw kunye neeparamitha zegroove, inokwamkela izixhobo eziluhlaza ze-PE ezinezalathisi ezinyibilikayo ezahlukeneyo. Ingasetyenziselwa ukukhutshwa kwemibhobho ye-PE, iiprofayili, kunye neefilimu, kunye ne-PE pelletization kunye nokuguqulwa (okufana nokuqiniswa kweglasi kunye nokuguqulwa kwe-flame retardant). Kufanelekile ngokukodwa ukuveliswa kweebhetshi ezincinci kunye neentlobo ezininzi zeemveliso ze-PE.

Iinkcukacha zeMveliso

Ubushushu obuphezulu, ukuchaneka komatshini, kunye neenkqubo ze-nitriding ziqinisekisa ukusebenza okubanzi kwamacandelo aphambili.

Iindawo ezinobungozi ze-screw kunye ne-barrel ziqiniswa nge-alloy ye-nickel-tungsten alloy layer, ukufikelela kwi-2-3mm umaleko obunzima kunye nokuphucula kakhulu ukuxhathisa ukunxiba.
