Iindaba zeshishini

Khetha umgca we-screw pelletizing line xa i-feedstock isele isondele ekuqulunqweni kokugqibela kwaye imisebenzi ephambili izinzile ukuhambisa, ukunyibilika, ukunyibilika ukunyibilika, ukuveliswa koxinzelelo kunye nokusika i-pellet. Yisiqalo esisebenzayo sokubuyisela i-PE okanye i-PP, i-pelletizing elula, umsebenzi webhubhoratri kunye nemveliso encinci ukuya kwephakathi. Khetha umgca we-twin-screw pelletizing xa umatshini kufuneka udibanise kunye nepelletize. Ifaneleka ngcono kwizihluzi, ii-pigments, i-polymer blends, i-masterbatch, iiplastiki ezilungisiweyo, imijelo emininzi yokutya kunye nokuchithwa okunamandla. Musa ukuthenga umgca we-twin-screw kuphela ngenxa yokuba imveliso yawo edwelisiweyo iphezulu. Yithenge xa ​​imisebenzi yayo yenkqubo ihambelana nokuqulunqwa.

Khetha isikrufu seplanethi xa ulwakhiwo lufuna ukuxubana okugqwesileyo kokusasazwa, indawo ebanzi yokuhambisa ubushushu, isenzo sokuzisula okanye ukucima i-degassing, ngakumbi nge-PVC evakalelwa ngubushushu, iikhompawundi ezizaliswe kakhulu, i-elastomers, i-adhesives kunye nezixhobo ezidibeneyo. Hlala nge-screw enye xa inkqubo izinzile kwaye idinga ukunyibilika kwezoqoqosho, ukuhambisa kunye noxinzelelo. Khetha isikhonkwane esijikelezayo xa udityaniswa ngesantya esiphezulu, ukondla ecaleni okubhetyebhetye okanye umsebenzi owomeleleyo wokusasaza yeyona nto iphambili. Ukuba ukufa kufuna uxinzelelo olungaphezulu kunokuba icandelo leplanethi linokubonelela, cwangcisa inqanaba loxinzelelo olusezantsi ngaphambi kokuyalela.

Khetha incam yesikrufu sokubumba ngenaliti ngezinto ezine: uyilo lwevalvu engabuyiyo, isikrufu esichanekileyo kunye nojongano lomphanda, iresin esetyenzisiweyo kunye nesihluzi, kunye nepateni yokunxiba yendibano ekhoyo. Imodeli yomatshini yodwa ayanelanga xa iinguqulelo, ukulungiswa kwangaphambili okanye izikrufu ezingekho mgangathweni zinokuba khona. Ukufumana iodolo yokutshintsha, thumela umzobo wokuqala xa ukhoyo, emva koko uqinisekise intambo, igxalaba, ubude bencam, ukuhamba ngeringi, isihlalo, idiameter yangaphandle kunye neepaseji ezinyibilikayo ngokuchasene nomatshini uqobo. Ucaphulo olulungileyo luqala ngejometri. Unyango lwezinto eziphathekayo kunye nomphezulu luza ngokulandelayo.

Khetha i-nitriding xa umphezulu wentsimbi ecociweyo ulingana nesinxibo esiqinisekisiweyo, umhlwa kunye nobukhulu bomsebenzi. Khetha i-flight hardfacing okanye olunye ulwakhiwo lwe-bimetallic xa iprojekthi idinga i-alloy eyahlukileyo kwindawo ephezulu yokunxiba. Kwinkonzo eqatha, impendulo engcono inokuba sisikrufu sobuso obuqinileyo esinombhobho we-bimetallic ohambelanayo. Akukho khetho luphezulu ngokuzenzekelayo. Qala ngemowudi yokungaphumeleli, emva koko uvume isikrufu kunye nezixhobo zomgqomo, iindawo zomaleko, indlela yokucubungula kunye neendlela zokuhlola kunye.

Ukonyusa isantya se-screw kudla ngokunyusa ukuhamba kotsalo kunye nesantya apho imathiriyeli ingena khona kwinkqubo, kodwa ubudlelwane abunamda okanye mgca ngokugqibeleleyo. I-rpm eninzi inokongeza ubushushu be-chear, inciphise ixesha lokuhlala kwaye iveze isondlo esibuthathaka okanye icandelo lokunyibilika. Guqula enye iguquguqukayo elawulwayo ngexesha, linda imeko ezinzileyo, uze uthelekise imveliso, inyibilika iprofayili yobushushu, uxinzelelo, umthwalo wemoto kunye nomgangatho wemveliso. Yima xa enye yezo ifikelela kumda wayo ovunyiweyo, nokuba i-drive inokujika ngokukhawuleza.

Sebenzisa indlela eyakhiweyo. Qala ngenkqubo yokucoca evunyiweyo yomthengisi kunye nomatshini ngelixa i-extruder ihlala iphantsi kolawulo oluqhelekileyo lokusebenza. Ukuba intsalela iyabuyiswa okanye isikrufu kufuneka sivele, siyeke, sibeke bucala kwaye uqinisekise amandla ayingozi ngokwenkqubo yesityalo. Kwisikrufu esisusiweyo, sebenzisa izixhobo ezivunyiweyo ezingonakalisi. Isikhokelo soshishino sicebisa izixhobo zobhedu, igawusi yobhedu kunye nelaphu lomqhaphu, kwaye ilumkisa ngokuchasene nezikrweqe zentsimbi kunye nokufudumeza kwetotshi yendawo. Hlola iindawo ezicocekileyo phambi kokuba wenze isigqibo sokuba ingxaki igugile.
