Buyisela isikrufu esinye se-extruder xa ukuguga okulinganisiweyo okanye umonakalo kuthintela uyilo olukhoyo ekwenzeni umsebenzi walo. Yiphucule xa isikrufu sivakala ngoomatshini-okanye sifuna ukutshintshwa-kodwa utshintsho olubhaliweyo kwi-resin, umgangatho wemveliso okanye imveliso ifuna isicwangciso esahlukileyo sokunyibilika, ukuxuba, ukuphuma okanye ukunxiba. Ngaphambi kwesigqibo nasiphi na, jonga umgqomo kunye nawo wonke umgca: isikrufu esitsha asikwazi ukulungisa ukutya okungalunganga, i-resin emanzi okanye ukufa okuthintelweyo.

Esona sikruru sibalaseleyo seso sisombulula umsebenzi wokunciphisa umgca wakho: ukondla, ukunyibilika, ukuxuba, ukukhupha umoya, okanye ukumpompa ngokuchasene noxinzelelo lokufa. Qala nge-resin kunye nefom yokutya, emva koko uhlolisise i-bottleneck yokwenyani ngaphambi kokukhetha isiqhelo, isithintelo, ukuxuba, okanye ukuyila umoya. Isikrufu esiphucula umsebenzi omnye sinokwenza omnye ube mandundu, ngoko ke umatshini, umgqomo, kufa, kunye novavanyo lokwamkelwa kufuneka lucaciswe kunye.

Ukuba i-resin yakho okanye i-compound ifika ilungele i-extrusion kwaye ingxaki eyinhloko i-melting stable kunye nokuhanjiswa koxinzelelo, qala nge-screw echazwe ngokufanelekileyo. Ukuba i-extruder kufuneka idibanise izithako ezihlukeneyo, ifake umgubo onzima okanye i-filler feeding, okanye ixhase ngakumbi ukungena kwe-venting, ukuvavanya i-architecture efanelekileyo ye-twin-screw; kumbhobho wePVC okanye iiprofayili, zibandakanya i-conical twin-screw option apho inkqubo yayo ifanelekile.

Musa uku-odola isikrufu segranulation esicacileyo kwifoto yamachaphaza amnyama kuphela. Rekhoda xa kuvela iziphene, jonga i-feed and downstream, thelekisa iimeko zokusebenza, emva koko ucoce kwaye ulinganise i-screw kunye ne-barrel phantsi kwenkqubo yokugcinwa evunyiweyo yesityalo. I-Nanhaiya's transparent granulation screw single igxininisa utshintsho olugudileyo, ukunyibilika okulawulwayo kunye nokugqitywa komphezulu. Ezo mpawu zibalulekile xa ijometri ekhoyo okanye umphezulu ngokwenene ingumthombo wemathiriyeli egciniweyo okanye ethotyiweyo.

Cacisa isikrufu sogwebu esinye se-PS ngokuchaza ifom yokutya kunye neresiphi, yintoni ekufuneka inyibilikiswe kwaye ixutywe phambi kokwandiswa kwerhasi, umphanda osele ukho kunye nojongano lokufa, kunye neendlela zokwamkelwa ezilinganisekayo zemveliso yogwebu. Nanhaiya kaThixo PS ugwebu isikrufu esinye isebenzisa ingqiqo L / D yoyilo elide, icandelo feed enenjongo yokuhambisa recycled PS kunye arhente nucleating, kunye nokukhetha Maddock-uhlobo okanye pin icandelo lokuxuba. Akukho nanye kwezo mpawu ezithatha indawo yedatha yakho yokwenyani.

Ukuthenga i-granulation parallel twin screw, cacisa i-feedstock echanekileyo kunye ne-pellet ekujoliswe kuyo, ukujikeleza komatshini kunye nejometri ye-screw-pair, imimandla yokusebenza, i-barrel fit kunye nolwakhiwo olufunekayo lokunxiba. Iphepha lemveliso yegranulation kaNanhaiya lidwelisa i-38CrMoAlA, unyango lobushushu, i-nitriding, i-chrome kunye nexabiso lereferensi ye-bimetal, kunye nezinto eziqhelekileyo kunye nokukhethwa koqwalaselo lwe-thermoplastics enyulu kunye ne-recycled. Khetha ulwakhiwo olunye oluchaziweyo lweendawo ezicwangcisiweyo kunokuphatha lonke ixabiso elidwelisiweyo lomphezulu njengophawu kwisikrufu ngasinye. Umyalelo ugqityiwe xa ukwachaza iirekhodi zohlolo kunye nolingo kwiresiphi yemveliso. Ukuhamba okufutshane kunye ne-resin elula akubonisi ukuba i-screw iya kwenza i-pellet efunekayo ukusuka kumxube onzima ohlaziyiweyo.
