Lena inqubo yokukhiqiza yebhizinisi lokukhiqiza ibhokisi lokudla, ungabhekisela ekufundeni ulwazi olufanele lweroukubumba.
I-Rotomolding kuyindlela entsha futhi ethuthukisiwe yokukhiqiza yokucubungula ipulasitiki, ebonakala ngokuthi:
1, ilungele ukucutshungulwaimikhiqizo emikhulu engenalutho, njengeithangi lamanzi, ithangi likawoyela, imishini emikhulu yokuzilibazisa, udonga lokuhlukanisa, njll.
2,Izindleko zokucubungula ziphansi, ikakhulukazi izindleko zesikhunta ziyi-1/3 kuphela yesikhunta somjovo. Ububi bayo ukufunwa okuphezulu kwezinto zokusetshenziswa, futhi ukunemba kokucubungula umkhiqizo oqediwe kubi uma kuqhathaniswa nokubumba umjovo.
Inqubo yayo yokukhiqiza imi kanje:
一,Ukulungiswa kwezinto zokusetshenziswa
(一) Izidingo zezinto ezingavuthiwe zei-rotomolding ukukhiqizwa
I-1.melting index ngokuvamile ayikho ngaphezu kuka-5.0g/10min.
Izinhlayiya ze-2.powder 30 ~ 60 mesh (izinhlayiya eziyindilinga azikwazi ukuba nenani elikhulu lomsila nama-prisms, izinhlayiya ze-flake).
3.somile.
(二) Izidingo zezinto ezingavuthiwe zeukukhiqizwa kwepulasitiki
I-LLDPE yezinga elilodwa lezintambo kunzima ukuqinisekisa izidingo ezithile zemikhiqizo (njengamabhokisi okugcina impi akhiqizwa inkampani yethu), ngakho-ke izinto eziyinhlanganisela (ezaziwa nangokuthi ukuguqulwa kwepulasitiki) zivame ukusetshenziswa, njenge-7042 kanye ne-UR644 impahla enoketshezi oluhle. kodwa amandla anganele. Ngakho-ke ukuze uqinisekise ikhwalithi yemikhiqizo ethile, 7042, 6090, 500S noma UR644, A760. Ifomula yempahla eluhlaza yomkhiqizo othile itholakala ngemva kwamashumi ezigidi zokuhlolwa kwesayensi, okuyimfihlo, okunelungelo lobunikazi, noma ubani akakwazi ukushintsha ifomula ngaphandle kokuhlola.
Umkhiqizo othize kufanele futhi wengezwe ngokusho ukusebenza komkhiqizo, ezinye master, Antioxidants, ezifana ukukhiqizwa umbala ukujoyina roll plastic grade master. Umkhiqizo usetshenziswa ngaphandle isikhathi eside, wengeza ama-antioxidants, ukukhiqizwa kwezinto ezivimbela umlilo, ama-anti-aging agents, abagqugquzeli nokunye.
(三) inqubo ethile yezobuchwepheshe
1. Ngokusho kokuhlelwa komholi, zonke izinhlobo zezinto ezingavuthiwe nama-accelerator ezisohlwini lwefomula yomkhiqizo zifakwa ku-mixer ngabasebenzi abanikezwe ngokukhethekile, futhi i-mixer ixutshwa ekuqaleni kwe-mixer. Isikhathi sokuxuba singu->10 wamaminithi (i-mixer ihlukaniswe yaba i-mixer evamile kanye ne-mixer enesivinini esikhulu, futhi kuyanconywa ukusebenzisa i-mixer enesivinini esikhulu uma isikhwama sivuma. Iphuzu eliyinhloko lale nqubo isilinganiso esinembile sazo zonke izinhlobo ze izinto ezingavuthiwe, okufanele zisetshenziswe nezinsimbi ezisezingeni elifanele.
2, umshini we-extrusion granulation opharetha one-hand disk motor pulley, umshini ungasebenza kalula, impahla ngemuva kokuxuba i-batch emshinini we-granulation, inkinobho yemoto nokunye. Ngemuva kokuthi i-ammeter ye-motor ikhuphuka, vala inkinobho yokushisa futhi ulungise izinga lokushisa kwendawo yokushisa. Inkampani yami uthenge umshini granulating ihlukaniswe yaba izindawo ezine zokushisisa, kusukela hopper phambili ngokushintshana: indawo ngayinye, ngokuvamile 150 ℃. Indawo yesibili ingu-180 ℃. Ngemva kokuqeda indawo yesithathu 180 ℃. Ikhala lingu-190 ℃.
Ngemuva kokuthi umugqa wezinto ezikhishiwe upholiswe ithangi lamanzi, ufakwa ku-granulator futhi ukushintsha kwamandla we-granulator kuyavalwa. Umshini we-pelleting uzodonsa ngokuzenzakalelayo emgqeni wezinto ezibonakalayo ukuze uhlatshwe. Umshini wokwenza umshini kufanele abheke ukusebenza kwe-extruder, uma kutholakala lapho kulindeleke ukuthi kuphume i-extruder vent, kufanele kunqanyulwe umthombo kagesi ngokushesha futhi kuhlale ngemva kokuba umshini uyeka ukusebenza ngokuphelele uvale ikhala, ushintshe ube unenetha elisha. (anezikhala ezindala ngaphandle kokulimala ngemuva komlilo, namanje zingakwazi ukuqhubeka nokusebenzisa), i-extrusion granulator evuliwe kabusha, izinto zokusetshenziswa zepulasitiki inkampani njengento entsha, Empeleni, ingashintshwa kanye ngosuku. Ngemuva kwe-extrusion, impahla kufanele yomiswe kahle emoyeni ngokuya ngesimo sangempela sezinto ngaphambi kwe-granulation.
Inhloso yale nqubo ukuguqula izinto zokusetshenziswa. Qaphela: Izinga lokushisa lokushisa kwezinto zokusetshenziswa kufanele lilungiswe ngokuya ngezinto ezisetshenziswayo ezahlukahlukene.
I-Extruder granulator ine-screw ephindwe kabili namaphoyinti angama-screw point, i-cold cut kanye namaphoyinti ashisayo, inkampani isebenzisa i-cold cut granulator.
3. Ukugaya impushana kuyinqubo edingekayo ngaphambi kokukhiqizwa kokugoqa ngoba impahla esetshenziswa ekukhiqizeni i-powder material, kanti impahla eluhlaza ethengwe yimakethe yi-granule material. Ngemuva kokuthi u-opharetha we-granulator ehlole ukuthi akukho yini into yangaphandle emshinini, i-granular material emva kwe-granulation ifakwa ku-hopper, umshini wokugaya uqalisiwe, futhi isivinini sokuphakela siyalungiswa ukuze sigaywe. Ngemuva kokugaya, izinto zokusetshenziswa ziyomiswa ngendlela efanele, futhi izinga lokushisa lokumisa akufanele lidlule ku-30 ℃.
Le nqubo igxile kwikhwalithi yokugaya impushana, usayizi wezinhlayiyana we-30 ~ 60 mesh, izinhlayiya eziyindilinga, azikho imiphetho, amakhona, i-flake, izinhlayiya ezilandelanayo.
