Iindaba zeshishini

Ukuthenga i-WPC extrusion mold, thumela i-cross-section yokugqibela kunye nokunyamezela, i-polymer epheleleyo kunye nefomula yokuzalisa iinkuni, indlela yokulungiselela izinto eziphathekayo, ukukhutshwa okujoliswe kuyo kunye nesantya somgca, i-extruder interface, i-downstream layout epholileyo kunye nesicwangciso sokwamkelwa kwemveliso egqityiweyo. Phawula iindawo ezibonakalayo, iindonga ezibalulekileyo, iimbambo zangaphakathi, i-cavities, i-radii kunye nayiphi na i-embossing okanye isibonelelo sesanti kumzobo. Musa ukwamkela isixhobo kwingxelo eyomileyo yobukhulu kuphela. Qhuba ifomyula ekuvunyelwene ngayo ngomgca ocetyiweyo, vumela iprofayili ipholile, emva koko ulinganise imilinganiselo, udonga kunye nobukhulu beembambo, ukuthe tye, ukujija, ubume bomphezulu kunye nobunzima ngobude ngobude. Iimvavanyo zentsebenzo yemveliso zihlala zixanduva lomenzi wemveliso egqityiweyo.

Ukuthenga umbhobho we-extrusion die head, thumela umboneleli iiseti zedatha ezintlanu ezihambelanayo: izinto kunye nokuqulunqwa; umgangatho wombhobho, ububanzi kunye noluhlu lodonga; imveliso kunye nesantya somgca; i-extruder flange kunye ne-melt-inlet interface; kunye necalibrator esezantsi komlambo, ivacuum, ukupholisa kunye nelungiselelo lokukhupha. Isicelo esinika kuphela "ipayipi yePVC, i-110 mm" ayilungele ubunjineli. Eyona nto ibalulekileyo inqaku lekhontrakthi yimeko yokwamkelwa. Xela into ebonakalayo yokuvelisa, ubungakanani bombhobho, imveliso ezinzileyo, isantya somgca, ukufudumeza kunye nokusekwa kwenzwa, ukuhluka okuvumelekileyo kwodonga, ububanzi obungaphandle, i-ovality, imeko yomhlaba kunye neemvavanyo ezifunekayo zemveliso. Intloko yokudaya ibumba inyibiliko eshushu, kodwa ayinako ngokwayo ukuqinisekisa umbhobho wokugqibela opholileyo.

Ukulinganisa i-parallel twin screw kunye nokunxitywa komgqomo njengenkqubo ehambelanayo. Rekhoda izikrufu zozibini kwizikhululo ezibizwa ngokuba yi-axial station, zombini iilobe zomfanekiso-sibhozo zibhobho kwiindlela ezichaziweyo, ukucoceka kwe-screw-to-screw, umgama osembindini, ukumisa kunye nokulingana kwe-axial. Thelekisa imephu nomzobo ovunyiweyo. Iimpawu zinokubangela ukuhlolwa, kodwa imilinganiselo ithatha isigqibo sokuba ithathe indawo yezikrufu, umphanda okanye iseti epheleleyo.

Kwi-PVC ephezulu, cacisa iresiphi epheleleyo kwi-phr, indlela yokutya, imveliso yokuphela, imveliso efunekayo, ukujikeleza kwe-screw, umgama ophakathi, imilinganiselo yokudibanisa kunye nemephu yokugqoka zombini izikrufu kunye nemibhobho yombhobho. Khetha i-nitriding, i-chrome plating okanye umaleko we-bimetallic ngokuchasene nowona msebenzi wokunxiba. Vumela umzobo kunye nendlela yokuhlola phambi kokuba ixabiso libe yinto ethatha isigqibo.

Ukuba ukubunjwa kwesijivu sesitofu kuthatha ixesha elide, qinisekisa kuqala ukuba kulibazisa umjikelo. Emva koko jonga ukuqhubeka kokutya, isantya esisijiva sokwenyani, uxinzelelo lwangasemva kunye nobushushu ngokuchasene nereferensi ezinzileyo. Hlola ijometri kwaye unxibe xa ezo zitshekhi zingachazi ilahleko. Tshintsha amalungu kuphela emva kokuchonga umsebenzi wokunciphisa.

Khetha ibhodi ye-PVC yogwebu ye-conical twin screw barrel ejikeleze ukwakheka, ujongano lomatshini olukhoyo kunye nokunxiba okulinganisiweyo. Qinisekisa umzobo opheleleyo phambi kokuba ukhethe iperi yedayamitha. Cacisa ukukhuselwa kwe-nitriding okanye i-bimetal ngomsebenzi wemveliso, emva koko uvumelane ngovavanyo lokwamkelwa usebenzisa iresiphi yebhodi yakho yokwenene kunye neemfuno zomgangatho.
