Iyi ndiyo nzira yekugadzira bhizinesi rekugadzira bhokisi rekudya, unogona kureva kudzidza ruzivo rwakakodzera rwerotomolding.
Rotomolding inzira nyowani uye yepamberi yekugadzira yekugadzira epurasitiki, iyo inoratidzwa ne:
1, yakakodzera kugadziriswahombe makomba zvigadzirwa, zvakaita setangi remvura, tangi yemafuta, midziyo huru yekuvaraidza, rusvingo rwekuzviparadzanisa nevamwe, nezvimwe.
2,Mutengo wekugadzirisa wakaderera, kunyanya mutengo wekuumbwa ingori 1/3 yejekiseni mold.Kushata kwayo kudiwa kwakanyanya kwezvinhu zvakabikwa, uye iyo yakapedzwa kugadzirisa iko kurongeka kwakashata kana ichienzaniswa nekuumbwa kwejekiseni.
Kugadzirwa kwayo kunotevera:
一,Kugadzirira kwezvinhu zvakasvibiswa
(一) Raw zvinhu zvinodiwa kutirotomolding production
1.melting index kazhinji haisi kupfuura 5.0g/10min.
2.powder particles 30 ~ 60 mesh (mapande akatenderera haagoni kuva nenhamba yakawanda yemuswe uye prisms, flake particles).
3.dry.
(二) Zvinodiwa pane zvakabikwa zvekugadzirwa kwepurasitiki
Iro tambo-giredhi LLDPE inonetsa kuona izvo zvinodikanwa zvezvigadzirwa (senge mabhokisi ekuchengetedza ehondo anogadzirwa nekambani yedu), saka zvinhu zvinoumbwa (zvinozivikanwawo sekushandurwa kwepurasitiki) zvinowanzo shandiswa, senge 7042 uye UR644 zvinhu zvine fluidity yakanaka. asi simba risina kukwana.Saka kuitira kuve nechokwadi chemhando yezvigadzirwa, 7042, 6090, 500S kana UR644, A760.Chaiyo chigadzirwa chakagadzirwa mafomula chinowanikwa mushure memakumi emamiriyoni ekuedzwa kwesainzi, zvakavanzika, zvine patent, chero munhu haagone kuchinja fomula pasina kuyedza.
Chigadzirwa chimwe chete chakasarudzika chinofanira kuwedzerwawo zvinoenderana nekuita kwechigadzirwa, vamwe tenzi, antioxidants, senge kugadzirwa kweruvara kujoina roll epurasitiki giredhi master.Chigadzirwa chacho chinoshandiswa kunze kwenguva yakareba, kuwedzera antioxidants, kugadzirwa kwezvinhu zvinopisa moto, anti-aging agents, vanokurudzira uye zvichingodaro.
(三) iyo chaiyo tekinoroji maitiro
1. Zvinoenderana nekurongeka kwemutungamiri, marudzi ese emhando yezvigadzirwa uye accelerator akanyorwa muforoma yechigadzirwa anoiswa mumusanganisi nevashandi vakanyatsopihwa, uye musanganisi anosanganiswa pakutanga kwemusanganisi.Nguva yekusanganisa i> 10 maminetsi (musanganisi wakakamurwa kuita musanganiswa wakajairwa uye unomhanya-mhanya musanganisi, uye zvinokurudzirwa kushandisa inomhanya-mhanya kana homwe ichibvumidza. mbishi zvinhu, izvo zvinofanirwa kushandiswa neanokwanisa chiyero chiridzwa.
2, extrusion granulation muchina opareta neruoko dhisiki mota pulley, muchina unogona kumhanya zviri nyore, izvo zvinhu mushure mekusanganisa batch mumushini wegranulation, mota bhatani zvichingodaro.Mushure mekunge mota ammeter yasimuka, vhara bhatani rekudziya uye gadzirisa tembiricha yenzvimbo yekudziya.Kambani yangu yakatenga muchina wegranulating wakakamurwa kuita ina yekudziya nzvimbo, kubva kune hopper kuenda mberi: imwe neimwe nzvimbo, kazhinji 150 ℃.Nzvimbo yechipiri ndeye 180 ℃.Mushure mekupera kwechitatu zone 180 ℃.Mhuno inosvika 190 ℃.
Mushure meiyo extruded material strip yakatonhodzwa netangi remvura, inopinzwa mugranulator uye simba rekuchinja regranulator rakavharwa.Muchina wepellet unobva wadhonza otomatiki mumutsetse wezvinhu wekupeta.Kugadzira muchina mushandisi anofanirwa kuona kushanda kweiyo extruder, kana yakawanikwa kune iyo inotarisirwa kusvina kunze extruder vent, inofanira kubva yagurwa magetsi sosi uye kugara mushure mekunge muchina wamira kushanda zvachose kubva pamhino extrusion kufa, chinja kuita mesh nyowani. (chembere mesh pasina kukuvadzwa mushure memoto, ichiri kuramba ichishandisa), yakavhurwazve extrusion granulator, epurasitiki mbishi zvinhu kambani sechinhu chitsva, Muchidimbu, inogona kuchinjwa kamwe chete pazuva.Mushure me extrusion, zvinhu zvinofanirwa kuve zvakaomeswa nemhepo zvinoenderana nemamiriro chaiwo ezvinyorwa pamberi pegranulation.
Chinangwa chemuitiro uyu ndechekugadzirisa zvinhu zvakasvibiswa.Ongorora: Kudziya kwekushisa kwezvinhu zvakasvibirira kunofanirwa kugadziridzwa zvinoenderana neakasiyana mbizha.
Extruder granulator ine kaviri screw uye single screw point, inotonhora yekucheka uye inopisa mapoinzi, kambani iri kushandisa inotonhora yekucheka granulator.
3. Kukuya hupfu chinhu chinodiwa usati wakungurutsa kugadzirwa nekuti zvinhu zvinoshandiswa mukukungurusa kugadzirwa ihupfu, uye iyo mbishi inotengwa nemusika ndeye granule material.Mushure mekunge mugadziri wegranulator atarisa kuti hapana nyaya yekune dzimwe nyika mumushini, iyo granular zvinhu mushure mekuiswa muhopi, muchina wekukuya unotangwa, uye kumhanya kwekudya kunogadziridzwa kukuya.Mushure mekugaya, zvigadzirwa zvinoomeswa sezvakakodzera, uye tembiricha yekuomesa haifaniri kudarika 30 ℃.
Iyi nzira inotarisa pamhando yehupfu hwekukuya, particle size ye 30 ~ 60 mesh, zvidimbu zvakatenderera, pasina mipendero, makona, flake, trailing particles.
