Izindaba Zemboni

Khetha umugqa we-pelletizing onesikulufu esisodwa lapho i-feedstock isivele iseduze nokwakhiwa kokugcina futhi imisebenzi eyinhloko izinzile ukudlulisa, ukuncibilika, ukuncibilika kokuncibilika, ukukhiqizwa kwengcindezi kanye nokusika kwe-pellet. Kuyisiqalo esisebenzayo sokugaya okungaguquki kwe-PE noma i-PP, ukuphindaphinda kabusha okulula, umsebenzi waselabhorethri kanye nokukhiqizwa okuncane kuya kokuphakathi. Khetha umugqa ohambisanayo we-twin-screw pelletizing lapho umshini kufanele uhlanganise kanye ne-pelletize. Ifaneleka kangcono kuma-fillers, ama-pigments, ama-polymer blends, i-masterbatch, amapulasitiki aguquliwe, ukusakazwa okuningi kokuphakelayo kanye nokuqothulwa okunamandla. Ungawuthengi umugqa we-twin-screw kuphela ngoba ukuphuma kwawo ohlwini kuphezulu. Ithenge uma imisebenzi yayo yenqubo ifana nokwakhiwa.

Khetha isikulufu seplanethi uma ukwakheka kudinga ukuxutshwa okuhle kakhulu kokusabalalisa, indawo ebanzi yokudlulisa ukushisa, isenzo sokuzisula noma ukukhishwa kwegesi okuhleliwe, ikakhulukazi nge-PVC ezwela ukushisa, izinhlanganisela ezigcwele kakhulu, ama-elastomer, izinto zokunamathisela nezinto eziyinhlanganisela. Hlala nesikulufu esisodwa lapho inqubo izinzile futhi idinga ngokuyinhloko ukuncibilika okongayo, ukudlulisa nokucindezela. Khetha isikulufu esizungezayo esingamawele lapho ukuhlanganisa ngesivinini esikhulu, ukuphakela okuseceleni okuguquguqukayo noma umsebenzi ohlakazekayo onamandla kungukuhamba phambili. Uma ukufa kudinga ingcindezi engaphezu kwaleyo ingxenye yeplanethi inganikeza, hlela isigaba sokucindezela phansi komfula ngaphambi koku-oda.

Khetha ithiphu yesikulufu sokubumba ngomjovo ngezinto ezine: idizayini yevalvu engabuyi, isikulufu esiqondile kanye nesixhumi esibonakalayo somphongolo, inhlaka ecutshunguliwe nesigcwalisi, kanye nephethini yokuguga yokuhlanganisa okukhona. Imodeli yomshini iyodwa ayanele uma izinguqulo, ukulungiswa kwangaphambilini noma izikulufu ezingajwayelekile zingase zibe khona. Ukuze uthole i-oda lokungena esikhundleni, thumela umdwebo wangempela uma utholakala, bese uqinisekisa intambo, ihlombe, ubude bethiphu, uhambo lwendandatho, isihlalo, ububanzi obungaphandle kanye namaphaseji ancibilikayo ngokumelene nomshini wangempela. Ikhotheshini enhle iqala ngejiyomethri. Ukwelashwa kwezinto ezibonakalayo nangaphezulu kuyalandela.

Khetha i-nitriding lapho indawo yensimbi elungisiwe ilingana nokuguga okuqinisekisiwe, ukugqwala kanye nomsebenzi we-dimensional. Khetha i-flight hardfacing noma okunye ukwakhiwa kwe-bimetallic lapho iphrojekthi idinga i-alloy ehlukile endaweni egqoke kakhulu. Ngesevisi eqinile, impendulo engcono ingaba isikulufu esinobuso obuqinile esinombhobho ohambisanayo we-bimetallic. Ayikho inketho ephakeme ngokuzenzakalelayo. Qala ngemodi yokwehluleka, bese uvumela isikulufu kanye nezinto zomgqomo, izindawo zesendlalelo, ukucubungula umzila kanye nemibandela yokuhlola ndawonye.

Ukwenyuka kwesivinini sesikulufu kuvame ukukhuphula ukugeleza kokuhudula kanye nezinga lapho okubalulekile kungena khona enqubweni, kodwa ubudlelwano abunamkhawulo noma abunamugqa ngokuphelele. I-rpm eyengeziwe ingase futhi yengeze ukushisa kwe-shear, ifinyeze isikhathi sokuhlala futhi iveze okuphakelayo okubuthakathaka noma ingxenye encibilikayo. Shintsha okuguquguqukayo okukodwa okulawulwayo ngesikhathi, linda isimo esizinzile, bese uqhathanisa okukhiphayo, iphrofayili yezinga lokushisa elincibilikayo, ingcindezi, umthwalo wemoto kanye nekhwalithi yomkhiqizo. Yima lapho enye yalezo ifinyelela umkhawulo wayo ogunyaziwe, ngisho noma idrayivu ingajika ngokushesha.

Sebenzisa indlela enezingqimba. Qala ngenqubo yokuhlanza evunyelwe wumhlinzeki womshini ngenkathi i-extruder isalokhu ingaphansi kolawulo oluvamile lokusebenza. Uma izinsalela zibuya noma isikulufu kufanele sivezwe, yima, uhlukanise futhi uqinisekise amandla ayingozi ngokuya ngenqubo yesitshalo. Ukuze uthole isikulufu esisusiwe, sebenzisa amathuluzi angalimazi agunyazwe yingxenye. Isiqondiso semboni sincoma amathuluzi ethusi, i-copper gauze nendwangu kakotini, futhi ixwayisa ngama-scrapers ensimbi kanye nokushisisa kwethoshi kwendawo. Hlola izindawo ezihlanzekile ngaphambi kokunquma ukuthi inkinga isigugile.
