Inzira ya rotomolding - Fata urugero rwibisanduku byibiribwa nkurugero

Nuburyo bwo kubyaza umusaruro uruganda rutunganya ibiryo, urashobora kohereza kugirango wige ubumenyi bujyanye narotomolding.

Kuzunguruka ni uburyo bushya kandi buteye imbere bwo gutunganya plastike, burangwa na:

1, ibereye gutunganywaibicuruzwa binini, nkaikigega cy'amazi, ikigega cya peteroli, ibikoresho binini byo kwidagadura, urukuta rwo kwigunga, n'ibindi.

2,Igiciro cyo gutunganya ni gito, cyane cyane ikiguzi ni 1/3 cyonyine cyo gutera inshinge. Ingaruka zayo ni nyinshi cyane kubikoresho fatizo, kandi ibicuruzwa bitunganijwe neza birakennye ugereranije no guterwa inshinge.

Ibikorwa byayo byo gukora ni ibi bikurikira:

一、Gutegura ibikoresho fatizo

(一) Ibikoresho bikenewe kurirotomolding umusaruro

1.gushonga indangagaciro muri rusange ntabwo irenze 5.0g / 10min.

2.ifu ya poro 30 ~ 60 mesh (ibice bizenguruka ntibishobora kugira umubare munini wumurizo na prism, uduce twa flake).

3.kuma.

(二) Ibisabwa kubikoresho fatizo kuriumusaruro wa plastiki

LLDPE imwe yo mu mugozi umwe iragoye kwemeza ibisabwa byihariye kubicuruzwa (nk'amasanduku yo kubika intambara yakozwe na sosiyete yacu), bityo ibikoresho bikomatanya (bizwi kandi ko bihindura plastike) bikoreshwa muri rusange, nk'ibikoresho 7042 na UR644 bifite amazi meza. ariko imbaraga zidahagije. Kugirango rero tumenye neza ibicuruzwa byihariye, 7042, 6090, 500S cyangwa UR644, A760. Ibicuruzwa byihariye byibanze biboneka nyuma ya miriyoni mirongo yubushakashatsi bwa siyanse, ibanga, byemewe, umuntu wese ntashobora guhindura formula atabanje kwipimisha.

Igicuruzwa kimwe cyihariye nacyo kigomba kongerwaho ukurikije imikorere yibicuruzwa, shobuja, antioxydants, nko kubyara amabara kugirango yinjire mu cyiciro cya plastike. Igicuruzwa gikoreshwa hanze igihe kinini, kongeramo antioxydants, gukora ibikoresho birinda umuriro, imiti igabanya ubukana, abamamaza nibindi.

(三) inzira yihariye yikoranabuhanga

1. Ukurikije gahunda yumuyobozi, ubwoko bwibikoresho byose byihuta byihuta byashyizwe kumurongo wibicuruzwa bishyirwa mubivanga nabakozi bashinzwe bidasanzwe, kandi kuvanga bivangwa mugitangira cya mixer. Igihe cyo kuvanga ni> iminota 10 (kuvanga bigabanijwemo kuvanga bisanzwe no kuvanga umuvuduko mwinshi, kandi birasabwa gukoresha imashini yihuta niba ikigega kibyemereye. Ingingo yingenzi yiki gikorwa ni igipimo nyacyo cyubwoko bwose. ibikoresho fatizo, bigomba gukoreshwa hamwe nibikoresho bisanzwe byujuje ibyangombwa.

2, extrusion granulation imashini ikoresha hamwe na disiki ya moteri ya moteri ya pulley, imashini irashobora gukora byoroshye, ibikoresho nyuma yo kuvanga ibyiciro mumashini ya granulation, buto ya moteri nibindi. Ammeter imaze kuzamuka, funga buto yo gushyushya hanyuma uhindure ubushyuhe bwahantu hashyuha. Isosiyete yanjye yaguze imashini isya igabanijwemo ibice bine byo gushyushya, uhereye kuri hopper ugana imbere: buri gace, muri rusange 150 ℃. Agace ka kabiri ni 180 ℃. Nyuma yo kunaniza zone ya gatatu 180 ℃. Izuru ni 190 ℃.

Nyuma yuko ibikoresho bisohotse bimaze gukonjeshwa n'ikigega cy'amazi, byinjizwa muri granulator hanyuma amashanyarazi ya granulator arafunga. Imashini ya pelleting izahita ikurura umurongo wibikoresho bya pelleting. Gukora imashini ikora imashini igomba kwitegereza imikorere ya extruder, niba ivumbuye ko biteganijwe ko izakuramo amashanyarazi, igomba guhita ihagarikwa kumashanyarazi hanyuma ikaguma nyuma yuko imashini ihagaritse gukora burundu izuru ripfa, ihinduka meshi nshya. . Nyuma yo gukuramo, ibikoresho bigomba guhumeka neza ukurikije uko ibintu bimeze mbere yo guhunika.

Intego yubu buryo ni uguhindura ibikoresho bibisi. Icyitonderwa: Ubushyuhe bwo gushyushya ibikoresho fatizo bugomba guhinduka ukurikije ibikoresho fatizo bitandukanye.

Extruder granulator ifite screw ebyiri na point imwe ya screw, gukonjesha gukonje hamwe nubushyuhe, isosiyete ikoresha granulator ikonje.

3. Gusya ifu ninzira ikenewe mbere yo gutangiza umusaruro kuko ibikoresho bikoreshwa mugukora ibicuruzwa ni ifu yifu, naho ibikoresho fatizo byaguzwe nisoko nibikoresho bya granule. Nyuma ya granulator ukora igenzura ko ntakintu kinyamahanga kiri mumashini, ibikoresho bya granulaire nyuma yo guhunika bishyirwa muri hopper, imashini yo gusya iratangira, kandi umuvuduko wo kugaburira uhindurwa kugirango usya. Nyuma yo gusya, ibikoresho fatizo bigomba gukama uko bikwiye, kandi ubushyuhe bwumye ntibushobora kurenga 30 ℃.
Ubu buryo bwibanda ku bwiza bwifu yo gusya, ingano ya 30 ~ 60 mesh, ibice bizengurutse, nta mpande, inguni, flake, ibice bikurikirana.
