Umshini wokukhipha we-WPC: imishini, inqubo, isingeniso sefomula

Njengoba izwe likhula kakhulu embonini yokuvikela imvelo, izindawo zengqalasizinda, ukuvikelwa kwemvelo, izinto ezintsha zamukelwa futhi zamukelwa emakethe. Lesi sihloko mayelana nemishini yokukhiqiza yemikhiqizo yezinkuni nepulasitiki ye-PP PE yasekhaya, izinqubo, ukwakheka kokwenza ikamu elilula, ukuze sikubhekisele kukho.

I. Ukukhipha

Manje, ukukhiqizwa kokucubungula ngokhuni-ipulasitiki kuhlukaniswe kakhulu ngezindlela zesinyathelo esisodwa kanye nezinyathelo ezimbili.
I-Wpc umugqa wephrofayili we-extrusioni-PP / PE ibuyele ku-resin, i-fiber (i-fiber yokhuni, i-fiber yoqalo, i-rice bran, njll.); izinto ezingaphili (i-calcium powder, i-talc); izithasiselo (izithambisi, izisabalalisi, izinto ezihambisanayo, izinto zokuhlanganisa, i-color powder, izinto ezishintshashintshayo, izinto ezikhipha umoya, njll.) ekushiseni okuphezulu okudingekayo kokuxuba emshinini wokuxuba obandayo ukuze uphole ufike kuma-degree angu-40-50 ngokusebenzisa i-granulation ye-flat double granulator bese ingezwa emikhiqizweni ye-extrusion ye-conical double extruder, lokhu kungumkhiqizo wezinyathelo ezimbili. Izinto ezixubile zengezwa ngqo ku-extruder ye-cone ngaphandle kokukhiqizwa kwesinyathelo esisodwa.

II. Ukukhetha imishini, isikhunta

1. Umdidiyeli
Imishini yokuxuba yendabuko iqukethe ukuxuba okushisayo nokubandayo. Ukuxuba okushisayo kuyi-resin, i-fiber, izinto ezingaphili, izithasiselo ebhodweni lokuxuba elishisayo ngokunyakaza okusheshayo ukuze kukhushulwe izinga lokushisa lezithasiselo ezincibilikisiwe futhi zihlakazeke ezintweni ezingaphili ze-resin ne-fiber, ukukhiqizwa kwezinto ezihlakazekile ngokulinganayo kanye nekhwalithi yomkhiqizo kuzinze kakhulu. Ukusabalala kwezinto kuhle noma kubi ngomklamo we-blade kanye nezinga lokuguguleka kwe-blade. Usayizi webhodwe lokuxuba elishisayo lasekhaya elivame ukusetshenziswa yi-200L/300L/500L/800L. Ibhodwe lokuxuba elibandayo liwukuxuba izinto ezishisayo ebhodweni lokuxuba elibandayo ngokusebenza kwejubane eliphansi kwemoto kanye nokugeleza kwamanzi ukuze kususwe ukushisa ukuze kuncishiswe izinga lokushisa lezinto. Izinto zixutshwa ngokuxuba okubandayo ekushiseni esikubekelwe ukukhiqizwa kanye nokuqina kombala, kususwe umhwamuko wamanzi futhi kuncishiswe ukubola kwezinto. Usayizi ojwayelekile webhodwe lokuxuba elibandayo eShayina yi-300L/600L/1000L/2000L.
Njengamanje, amakhasimende amaningi ngokwesimo sangempela sezinto ezibonakalayo, uma umswakama ungadluli ku-5%, ukusetshenziswa kwabaxubi abavamile ukuxuba izinto zokusetshenziswa, bese kuba ngqo ku-granulator, ukusetshenziswa komsebenzi wokukhipha i-granulator ukususa umswakama owedlulele; uma umswakama ungaphezu kuka-5%, ukusetshenziswa kokuxuba okushisayo, bese kuba ngqo ku-granulator, ukusetshenziswa kokuxuba ukushisa kwangaphambili ukuze kuqhutshekwe nokufakwa kwe-pellet, nakho kuyindlela yokonga amandla.
2. Ukukhetha imishini yokuhlanganisa izinkuni. Isetshenziselwa ama-granule okwakha izinkuni e-PP / PE ane-cone double kanye ne-flat double izinhlobo ezimbili, ama-granule epulasitiki e-cone double e-PP / PE awalungile kakhulu ngoba i-fiber kunzima ukuyihlakaza kulula ukuyihlanganisa, ukuze kuthinte ukusetshenziswa komkhiqizo njengokuthi: imikhiqizo emunca amanzi amaningi, kulula ukuyikhuhla njalo njalo. I-flat double ngeke ibonakale njengesenzakalo se-fiber agglomeration, ama-pellets ezinkuni e-PP / PE asekhaya asebenzisa i-flat double granulation. I-Jwell DAYUN Plastic Recycling Auxiliary Equipment Manufacturing Co., Ltd. ukukhiqizwa komshini wokufaka i-pelletizing, ukufaka i-pelletizing ngqo ngemva kokuchotshozwa, izinto zibe yi-extruder, konga isikhathi namandla.
3. Ukukhetha i-extruder: i-extruder yasekhaya, kungakhathaliseki ukuthi indlela yesinyathelo esisodwa noma ezimbili, isetshenziswa ngokuyisisekelo, i-cone double ukuze ikhiphe imikhiqizo. Ngenxa yokuthi okuqukethwe kwe-PP / PE wood-plastic fiber kuphezulu kakhulu emishinini (isikulufa, i-barrel), ukuguguleka nokuklebhuka kuyinto embi kakhulu, kuhlanganiswe ne-fiber, izithasiselo, i-PP / PE ibuyela ezintweni ngemuva kokushisa okuphezulu izokhiqiza i-asidi yamahhala futhi izokhiqiza izinga elithile lokugqwala kwesikulufa, i-barrel, ngakho-ke ikhwalithi ye-screw bar ibaluleke kakhulu. Njengamanje, abakhiqizi be-double alloy screw barrel, besebenzisa isakhiwo esihlukanisiwe, imbobo yangaphakathi yobuchwepheshe be-alloy sintering, bangandisa impilo yenkonzo ye-screw barrel.
4. Isikhunta esinemishini efanayo, ikhwalithi yensimbi kufanele ibe ukumelana nokuguguleka okuhle, impilo yenkonzo ende, ukwakheka kwesikhunta kuhle noma kubi ngokwekhwalithi yomkhiqizo, ukubumba, ukuqina komkhiqizo, isivinini sokukhiqiza. Ikakhulukazi imikhiqizo eqinile eqinile ezidingweni zesikhunta iphakeme.

III. Ukukhethwa kwezinto zokusetshenziswa

1. PP / PE emuva ekukhetheni izinto, emuva ekukhetheni okungcono kakhulu komunwe oncibilikayo akuphakeme kakhulu emuva kuya kokungcono kakhulu ku-1.0 noma ngaphansi. Umbala awumnyama kakhulu, usayizi wezinhlayiya uyafana, izinhlayiya azinazimbobo noma izimbobo ezimbalwa. Kungcono ukusebenzisa izinga lokubuyela emuva ezintweni, okunye ukubuyela emuva ezintweni sekusetshenziswe izikhathi eziningana, kuzonciphisa izakhiwo zemishini.
2. I-fibre choice mesh ku-50-80 mesh noma ngaphezulu, kanye nomlotha, okuqukethwe komswakama kuphansi kune-fibre engcono kakhulu (umlotha, umswakama kungaphansi kuka-5%) ukuhambisana kombala kanye nokufana.
3. Ukukhetha izithasiselo. Ukuze wenze umsebenzi omuhle wokukhetha izithasiselo ze-PP / PE zokhuni-zepulasitiki kubaluleke kakhulu, kuhlobene nokuzinza kokukhiqizwa, isivinini, ikhwalithi yomkhiqizo (ukubumba komkhiqizo, izakhiwo zemishini, izakhiwo zemishini, ukumuncwa kwamanzi, umkhiqizo ekusetshenzisweni kwenqubo yokuthi ngabe kukhona yini ukuna kwezithasiselo, njll.) kanye nokuphila komkhiqizo.

IV. Ukukhetha inqubo

Ukukhiqizwa kwepulasitiki yokhuni lwe-PP/PE ekhaya ngokuyisisekelo kuyindlela yokukhiqiza enezinyathelo ezimbili, inzuzo ukukhiqizwa okuzinzile kanye nekhwalithi yomkhiqizo.
1. Inqubo yokukhiqiza izinto zokusetshenziswa:
I-Wood fibre iyinto emunca kakhulu ngokuqukethwe kwamanzi okuvamile okungaba ngu-15% noma ngaphezulu, ukugcwalisa okungaphelele nakho kufinyelela ku-5% noma ngaphezulu, futhi okuqukethwe kwamanzi okuphezulu nokuphansi kuzothinta ukuzinza kokukhiqizwa kwepulasitiki, ikakhulukazi ukukhiqizwa kwepulasitiki yokhuni kanye nekhwalithi yomkhiqizo wesitha semvelo, njengokuthinta i-foam multiplier, umkhiqizo wesilinganiso sokumunca amanzi, umkhiqizo wokuguqulwa kwemikhiqizo, imikhiqizo yokumelana nesimo sezulu kanye nezinye izakhiwo zomzimba.
Ngakho-ke, kungcono ukulawula umswakama ngaphakathi kwe-1%. Lawula umswakama ofanele wefayibha kanye nokugcwalisa —– okungeziwe ku-mixer ephezulu —– okuxutshwe kuma-degrees ayi-100 —– engeza inani elifanele le-coupling agent —- okuxutshwe kuma-degrees ayi-110-115 —- cima imoto ayihambi vula isembozo se-mixer imizuzu emi-2-3 —– engeza i-PVC, iziqinisi —– ezixutshwe kuma-degrees angama-80 —– nezithambisi nezinye izithasiselo —– ama-degrees ayi-100 kanye nezinsiza zokucubungula, ama-ejenti e-foam ——120-125 i-uploading powder —– i-powder i-uploading ngemva kokuba imoto ima bese uvula isembozo imizuzu emi-2-3 ngaphambi kokuxuba i-handful yezinto ezilandelayo (kungcono ukuxuba i-handful ezinhlanu zezinto ukuze uhlanze i-mixer kanye) —– i-powder ethangini lokuxuba ukuze ifinyelele kuma-degrees angama-40 ingafakwa i-pellet noma ifakwe ekukhiqizweni kwe-twin-screw (ithangi lokuxuba kumele libe nomjikelezo wokupholisa amanzi). Ekuxubeni kumele uqaphele izinga lokushisa nesikhathi, njengokuxuba imbiza ebandayo evamile, ukuxuba izinto ezimbalwa cishe ngemizuzu engama-20-25, imbiza eshisayo cishe ngemizuzu eyi-12-15 (ukubeka izinga lokushisa cishe ngama-degrees ayi-125), uma kukhona umehluko wemizuzu emi-3 noma ngaphezulu, kungaba inkinga yomugqa wokuzwa izinga lokushisa noma ukulawula izinga lokushisa akuvunyelwe, noma ukugqokwa kommese womshini wokuxuba i-bullhorn kungathi sína. Lokhu kuzothinta ukuzinza kwe-foam multiplier, umbala. Ukuphalaza kuvame ukudinga ukunaka izinga lokushisa lokulawula izinga lokushisa linembile, kungakhathaliseki ukuthi ifeni isebenza ngokujwayelekile, usayizi wamanje, usayizi wezinhlayiya, ubuso, ubude, ukuthi izinto ezinamathelayo, ukuthi izinto zizinzile, azikwazi ukuphula izinto.

2. Inqubo yokukhipha: ukunaka okuyinhloko kulezi zici ezilandelayo
a. ukusetha izinga lokushisa le-extruder kwesigaba ngasinye, isihluthulelo isigaba sokucindezela, isigaba sokulinganisa, isikhunta. Ukunemba kokulawula izinga lokushisa, njengokulawula izinga lokushisa akuvunyelwe ukuthinta izinga le-foam nombala. Ukufaka igwebu ikakhulukazi ukusetha izinga lokushisa lesigaba sokucindezela kanye nesigaba sokulinganisa, ukubumba ikakhulukazi izinga lokushisa lesikhunta.
b. ukusebenza okuvamile kwefeni yesigaba ngasinye.
c. usayizi kanye nokuqina komsinga womsinga. Uma ukushintshashintsha komsinga womsinga kukhulu, kusho i-sliding agent. Izinsiza zokucubungula. Izingxenye ze-fibre ne-PVC zokusabalala azifani kakhulu.
d. umsingathi kumele agcine isivinini esifanayo, ngoba isivinini sesivinini sizothinta isiphindaphindi se-foam nombala.
e. izinga lokushisa lokomisa ngokuvamile libekwa kuma-degrees angu-60-80 phakathi, futhi livame ukugcinwa kumthamo wemigqomo ongaba ngu-80%, okusiza ekukhiqizweni nasekuzinzeni kombala ukuze kuthuthukiswe ikhwalithi ebonakalayo yemikhiqizo.
f. imibala ehlukene, imishini ehlukene, ubude besikhathi ama-pellets agcinwa ngaso ekukhiqizweni kwezilungiselelo ezahlukene zokushisa. Futhi ukugqwala ngokhuni-ipulasitiki yimvelo yangaphandle kanye nezinye izinto ezifana nokuphindaphinda ama-foam kunomthelela omkhulu ngakho-ke umqhubi kufanele azi ukubonakala kokuphazamiseka komkhiqizo okuhlukile lapho kulungiswa okufanele embonini.
