Uhlalutyo lwetekhnoloji yokuqhubela kweplastiki-kumgaqo wobuchwephesha wokuphuma

Umgaqo woMatshini

Indlela esisiseko yokuphuma ilula - isikroba sijikeleza emgqomeni kwaye sityhala iplastiki phambili. I-screw yeyokwenyani okanye ithambeka elisongelwe uLawulekazi. Injongo yayo kukwandisa uxinzelelo ukuze woyise ukumelana. Kwimeko yomthengisi, zintathu iindidi zokuxhathisa ezifuna ukoyiswa: Ukuxabana kwamasuntswana aqinileyo (Nike) ngokuchasene nodonga lwesilinda kunye nokuntywila phakathi kojikelezo lwe-screw (indawo yokondla ); Ukunamathela eludongeni lwegreni; Ukunganyangeki kwendlela yangaphakathi yokunyibilika njengoko ityhishiswa phambili.

Ukuba into ayihambi kwicala elinikiweyo, amandla okwinto engalungelelanisiweyo kwale ndlela. Isikhafu asihambi kwicala le-axial, nangona linokujikeleza kamva ecaleni komnqoboleko. Ke ngoko, amandla e-axial kwisikali silungelelene, kwaye ukuba iyasebenza phambili enkulu kwi-plast yeplastiki, ikwasebenza kwakhona ngasemva kwento engaphaya kwento. Apha, i-uproust ifakiwe kukuphazamiseka kwi-Ext kwi-Extund App.

Uninzi lwezikrelemnqa zizodwa zezona ntambo zisekunene, ezinjenge-screws kunye ne-bolts ezisetyenziselwa ukuncokola kunye noomatshini. Ukuba bajonga ngasemva, bajikeleza kwicala elichaseneyo kuba bazama ukuthoba i-barrel kangangoko kunokwenzeka. Kwelinye icala lesikrelemnqa, izikrelem ezimbini zijikeleza kwicala eligxunyekwe kwiisilinda ezimbini kwaye ziwele omnye komnye, umntu kufuneka abe sekhohlo kwaye enye mayibe sekhohlo. Kwelinye i-screws escal win, izikrikhi ezimbini zijikeleze kwicala elinye kwaye kufuneka zibe nesifundo esifanayo. Nangona kunjalo, kulo naliphi na icala, kukho i-thesther ethatyathwayo ethatyathwa amandla angasemva, kwaye umgaqo weNewton usasebenza.

2. Umgaqo we-thermal

Iiplasitiki ezikhoyo ze-thermoplastics - ziyanyibilika xa zishushu kwaye ziqinile ngokupholisa. Ivelaphi ubushushu beplastiki etyhidiweyo? Ukutyibilika phambi kwendawo yokuhlala kunye ne-barrel / i-shees yokufa kunokubaluleka ekuqaleni, nangona kunjalo, amandla okuphuma kwemoto-ukugcwala kwemoto ngokuchasene ne-virrel xa ijika i-screw - yonke le nto iguquliweyo Umthombo obalulekileyo wobushushu wePlastiki, ngaphandle kweenkqubo ezincinci, isikhafu esiphantsi sesantya, i-plastic ephezulu ye-plastics kunye nezicelo zokupheka.

Kuyo yonke eminye imisebenzi, kubalulekile ukuba uqonde ukuba i-heater ye-barrel ayingowona mthombo uphambili wobushushu, kwaye ke ifuthe lokuphuma (jonga i-11). Iqondo lokushisa lasemva kwe-cylindrinder lisenokuba lubalulekile kuba lichaphazela ireyithi yezithuthi ze-solids emazinyweni okanye ekutyeni. Iqondo lokufa kunye neqondo lokulwa lifanele libe liqondo lokufunwa limbonakalo okanye kufutshane neqondo lobushushu ngaphandle kokuba zisetyenziselwa injongo ethile efana netreying, ukuhanjiswa koxinzelelo.

3. Umgaqo wenkohliso

Uninzi lwabasebenzi, utshintsho kwizantya zescrew ufezekiswa ngokuhlengahlengisa isantya semoto. Imoto idla ngokujikeleza ngesantya esipheleleyo malunga ne-1750 RPM, kodwa oku kukhawuleza kakhulu kwisikrelemnqa. Ukuba ijikelezwe ngesantya esikhawulezayo, ubushushu obunzima kakhulu buveliswa kwaye ixesha lokuhlala leplastiki lifutshane kakhulu ukuba lilungiselele iyunifomu, eshukuma kakuhle. Inqanaba lokuphumelela eliqhelekileyo ukusuka kwi-10: 1 ukuya ku-20: 1. Inqanaba lokuqala linokuba yigiya okanye i-pulley, kodwa inqanaba lesibini lisebenzisa iigiya kunye nesikali sibekwe embindini wegiya enkulu yokugqibela.

Kumatshini abathile ohamba kancinci (njengamawele e-winvc), kunokubakho amanqanaba enkohliso 3 kunye nesantya esiphezulu esinokuba sezantsi njenge-30 rpm okanye ezantsi (ukuya kuthi ga kwi-60 yomlinganiso). Kwelinye icala, amanye isitayile esinde kakhulu sokuphazamiseka sinokuqhuba nge-600 i-RPM okanye ngokukhawuleza, ngaloo ndlela efuna inqanaba eliphantsi lokufumana inkohliso kunye nokupholisa okunzulu.

Ngamanye amaxesha inqanaba lokukhohlisa liyinto engekho mthethweni kunye nomsebenzi - kuya kubakho amandla amaninzi ukuyisebenzisa - kwaye kunokwenzeka ukongeza ibhlokhi ye-pulley phakathi kwemoto kunye nenqanaba lokuqala lokugcina inkohliso etshintsha isantya esiphezulu. Oku konyusa isantya seScrew ngaphezulu komda odlulileyo okanye ukwehla kwesantya esiphezulu sokuvumela inkqubo ukuba isebenze kwipesenti enkulu yesantya esiphezulu. Oku kuyakwandisa amandla akhoyo, ukunciphisa i-pharage kwaye uphephe iingxaki zemoto. Kuzo zombini iimeko, ukukhutshwa kunokukhulisa ngokuxhomekeka kwizinto kunye neemfuno zayo ezipholileyo.

4. Ukondla njengelipho

Ukuphuma kudlulisela amandla emoto, ngamanye amaxesha i-heater, kwiplastiki ebandayo, iguqula ukuba iqinile ukuze inyibilike. Ukutya kwegalelo kukuphola kune-borrel kunye neqondo lokuphumla komgangatho kwindawo yokutya. Nangona kunjalo, umphezulu we-barrel kwindawo yokutya phantse ihlala ingekaphezulu koluhlu lweplastiki yeplastiki. Ipholwane ngokudibana namasuntswana okutya, kodwa ubushushu bugciniwe bubushushu bubuyiselwe kwisiphelo esishushu esishushu kunye nokufudumeza. Kwanasemva kokuba ubushushu bube bubushushu bubanjelwe kukudalwa kwe-viscous kwaye akukho kufakelwa igalelo le-barrel kuyafuneka, kuya kufuneka i-heater yeposi. Eyona nto ibaluleke kakhulu yi-cartridge yendawo yokutya, ephantse ibe yi-HDPE.

Umphezulu wengcambu ye-Screat nayo ipholile kukutya kwaye isuswe kudonga lweglasi ngamasuntswana eplastiki (kunye nomoya phakathi kwamasuntswana). Ukuba isikhafu siyamisa ngequbuliso, ukutya oko kuyayeka, kwaye njengokufudumeza ukusuka kwindawo eshushu ngaphambili, indawo ye-screw iba nzima kwindawo yokutya. Oku kunokubangela ukubamba okanye ukungcamla kwamasuntswana kwiingcambu.

5. Kwindawo yokondla, bambelela kwi-cylinder kwaye batyibilika kwi-screw

Ukwenzela ukwandisa inani le-slids ezikhutshwe kwindawo yokutyisa i-barrel ye-barrel entsalela, amasuntswana kufuneka anamathele kwi-barrel kwaye afungelwe kwisikrelem. Ukuba amasuntswana anamathele kwingcambu yesikrelem, akukho nto ikhupha phantsi; Umthamo wesiqendu kunye nenani leenyibilikiswa. Esinye isizathu sokunamathela olihlwempu kwiingcambu kukuba iplastiki inokuphuphuma apha kwaye ivelise i-galls kunye namasuntswana afanayo, okanye athobele impahla kunye nokuqhekeza ngesantya sokukhupha isantya.

Uninzi lwe-plastic slide ngokwemvelo kuba bayabanda xa bengena, kwaye imbambano ayibeki iingcambu ezishushu njengeendonga. Ezinye izixhobo zinokubambelela ngakumbi kunokuba abanye: i-pvc eqingqiweyo, i-Amorphous Pet, kunye ne-colyollys esekwe kwiPolylelefin enepropathi yobunamathela enqwenelekayo.

Kwibarrel, iyimfuneko kwiplastiki ukuba ilandele apha ukuze ikhutshelwe kwaye ityhuselwe phambili ngumsonto wekrow. Kuya kufuneka kubekho ukulingana okuphezulu kwengqungquthela phakathi kweegranus kunye ne-borrel, kwaye ukulingana kokuxabana kukwaphenjelelwa ngamaqondo obushushu angasemva. Ukuba amasuntswana awayibili, bajikeleza endaweni ngaphandle kokuya phambili - yiyo ukuba kutheni ukondla okugudileyo akulunganga.

Ingqumbo engaphezulu ayisiyiyo kuphela into echaphazela ukutya. Amasuntswana amaninzi akaze achukumise i-barrel okanye ingcambu yesikrwqe, ngoko ke kufuneka kubekho unxibelelwano noomatshini kunye nokubonisa unxibelelwano ngaphakathi.

Isilinda esikhukulisekileyo sisimo esikhethekileyo. Umkhombe kwindawo yokutya kunye nendawo yokutya ingena esweni entsalela ye-barrel kwaye inamanzi athobekileyo. Intambo ityhila amasuntswana kwi-Groove kwaye wenza uxinzelelo oluphezulu kakhulu kumgama omfutshane. Oku kukhulisa ukunyamezelana okungaphantsi kwesikhafu esifanayo sekrikhi efanayo, ukuze ubushushu obuqinileyo buveliswe kwindawo engaphambili buncitshisiwe kwaye ubushushu obushushu buncitshisiwe. Oku kunokuthetha imveliso ekhawulezayo ekuphoxekeni kwefilimu yefilimu. Itanki ilungele ngokukhethekileyo kwi-HDPE, eyicotha iplasitiki eqhelekileyo ngaphandle kweplastiki efihliweyo.

6. Izinto ezibizayo kakhulu

Ngamanye amaxesha, iindleko ezibonakalayo zinokuphendula i-80% yeendleko zemveliso-ngaphezu kwazo zonke ezinye izinto-ngaphandle kwemveliso ebaluleke kakhulu kumgangatho kunye nokupakisha, njengabathathi-nxaxheba kwezonyango. Lo mgaqo ngokwendalo ukhokelela kwizigqibo ezibini: Iiprosesa kufuneka ziphinde zisebenzise i-scrap kwaye zibambeke kakhulu endaweni yezixhobo eziluhlaza, kwaye zilandele ukudimaka kangangoko kunokwenzeka ukunqanda ukuphathwa kweethagethi kunye neengxaki zemveliso.

7. Iindleko zamandla zingenakubalwa

Nangona umtsalane kunye neengxaki zokwenyani zomzi-mveliso ofanayo neendleko zamandla anyukayo, amandla afunekayo okuqhuba isiqwengana sexabiso elincinci lexabiso lemveliso. Oku kuhlala kunjalo kuba iindleko zezinto ezibonakalayo ziphezulu kakhulu kwaye umntu ophumeleleyo yinkqubo esebenzayo. Ukuba amandla amaninzi waziswa, iplastiki iya kushushu ngokukhawuleza kangangokuba ayinakulungiswa ngokufanelekileyo.

8. Uxinzelelo ekupheleni kwe-screw lubaluleke kakhulu

Olu xinzelelo lubonisa ukuxhathisa kwazo zonke izinto ezikhanyayo zesikere: isikrini se-filter kunye ne-shrenti engcolisekileyo ye-shredder, ityhubhu yokudluliselwa kwe-adaptha, kunye nokubumba ngokwakho. Ayixhomekekanga kuphela kwiJometri yala macandelo kodwa nakwiqondo lokushisa kwinkqubo, elichaphazela i-viscofity ye-resin kunye negalelo. Ayixhomekekanga kwi-screw uyilo, ngaphandle kokuba ichaphazela ubushushu, i-viscosity kunye negalelo. Ngenxa yezizathu zokhuseleko, iqondo lobushushu libalulekile - ukuba liphezulu kakhulu, ukufelwa kwaye ukubumba kunokuqhuma kwaye kulimaza abantu kufutshane nabantu okanye oomatshini.

Uxinzelelo luyingenelo ukuba luphawulwe, ngakumbi kumda wokugqibela wenkqubo ye-screaw enye (indawo yokupeyinta). Nangona kunjalo, uxinzelelo oluphezulu luthetha ukuba le moto kufuneka ikhuphe amandla ngaphezulu - kwaye ke iqondo lobushushu linyibilike - elinokuthi lilikhuphe umda woxinzelelo. Kwisikhuseli samawele, ukuzibandakanya kwezikrelem ezimbini omnye komnye ngumgadi ofanelekileyo, ngoko ke akukho xinzelelo luyimfuneko kule njongo.

Kwimveliso yamagumbi amdaka, ezinje ngee-tubes ezivela kwisigcawu esigxile kwisigcawu esisebenzisa iibakaki, kufuneka kudalwe uxinzelelo oluphezulu kwi-morance ukuze uncede kwimilambo eyahlukileyo. Ngaphandle koko, imveliso ecaleni komgca we-Weld inokuba buthathaka kwaye iingxaki zinokwenzeka ngexesha lokusetyenziswa.

9. Imveliso = Ukususwa kwentambo yokugqibela /---Uxinzelelo lokuhamba kunye nokuvuza

Ukufuduswa kwentambo yokugqibela kubizwa ngokuba kukuhamba okuhle kwaye kuxhomekeke kuphela kwi-geometry ye-screw, isantya sekrisk kunye nokuxinwa komhlaba. Ilawulwa ngumsinga woxinzelelo kwaye iquka isiphumo sokutsala isiphumo esinciphisa iziphumo (eziboniswe ngoxinzelelo oluphezulu) kunye nakuphi na ukwenza umphumo wokutya okuphelisa iziphumo. Ukuvuza kwintambo kunokuba kukwindlela ezimbini.

Kukwabalulekile ukubala iziphumo nge-RPM nganye (ukujikeleza) njengoko oku kubonisa nakuphi na ukuhla komthamo wempompo ngesakhelo ngexesha. Ezinye zobalo ezinxulumene noko yimveliso nganye yehashe okanye i-kilowatt esetyenzisiweyo. Oku kubonisa ukusebenza kakuhle kwaye kuyakwazi ukuqikelela amandla emveliso yemoto enikiweyo kunye ne drive.

10. Ixabiso le-Shear idlala indima enkulu kwi-viscosity

Yonke iplasitiki eqhelekileyo inamachiza aphantsi kwepropathi, okuthetha ukuba i-vickosity iphantsi njengoko iplastiki ihamba ngokukhawuleza kwaye ikhawuleze. Le mpembelelo yetrastiki iphawuleka kakhulu. Umzekelo, ezinye ii-PVCs zanyusa umgangatho wokuhamba ngento ye-10 okanye ngaphezulu xa i-quast iphindwe kabini. Ngokuchasene noko, amandla e-shiar shear ayincitshiswa kakhulu, kwaye ireyithi yokuhamba inyuswe kuphela ngamaxesha ama-3 ukuya kwango-4 xa ukuphindwe kabini. Iziphumo zokuncitshiswa kwe-shear encitshisiweyo zithetha i-viscofity ephezulu phantsi kweemeko zokuphuma, ezinokuthi zithethe ngakumbi amandla ezemoto afunekayo. Oku kunokuchaza ukuba kutheni i-LDD isebenza kubushushu obuphezulu kune-LDPE. Ixabiso lokuhamba livezwe kwi-Shear Inqanaba, malunga ne-100 s-1 kwi-screw channel, phakathi kwe-100 ne-100 s-1 kwiiprofayili ze-100 kakhulu, kwaye inkulu kune-100 ye-S-1 kumngxunya kwaye incinci I-Die Deps. Inyibilikisa i-Counts yomlinganiso ngumlinganiselo oqhelekileyo osetyenzisiweyo we-viscosity kodwa ibuyiselwe (umz. Ukuhamba / ukuntywila kunokugaya okanye ukuhamba). Ngelishwa, umlinganiso ayisiyo mlinganiso wokwenene kwisitepter enenqanaba le-10 le-Shear ye-10 s-1 okanye elingaphantsi kunye nenqanaba lokuhambahamba ngokukhawuleza.

11. Imoto ichasene nesilinda, kwaye isilinda sichasene nemoto.

Kutheni le nto impembelelo yolawulo yesilinda engasoloko ifana njengoko kulindeleke, ngakumbi kwindawo yokulinganisa? Ukuba isilinda sishushu, isilinda
