Isikrufu sokutofa i-L/D ratiobubude bokusebenza bohlulwe nge-screw diameter, kwaye uninzi lwezikrufu zokutofa zibaleka ngo-18:1 ukuya ku-25:1. Nantsi into ekungekho phepha elikuxelela kona: awukwazi ukutshintsha i-L/D kumatshini osele ungowakho. Ubude bulungiswe ngumbhobho. Yintoni onokuyitshintshaIdayamitha yesikrufu, kunye nomgqomo osisigxina ukuba ukhetho olunye luhambisa i-L / D, umthamo wokudubula, kunye noxinzelelo lwenaliti kunye, kumacala achaseneyo. Isikrufu esincinci sinika i-L/D ephezulu, isithonga esincinci, kunye noxinzelelo olungaphezulu. Tshatisa olo rhwebo kwi-resin yakho kunye nenxalenye yakho, kwaye uninzi lwemibuzo ye-L/D iziphendula ngokwayo.
Kuthethwa Ntoni Umlinganiselo we-L/D kwisikrufu sokutofa
I-L/D bubude bokusebenza kwesikrufu (L) esahlulwe ngedayamitha yaso yangaphandle (D). Isikrufu ngama-22 ubude kunobubanzi baso sine-L/D ye-22:1.
Umlinganiselo ulinganisa ngobungakanani. Isikrufu esiyi-40 mm ku-22:1 sinobude bokusebenza obuyi-880 mm. I-80 mm Screw ku-22:1 yi-1,760 mm ubude. Umlinganiselo ofanayo, oomatshini abahluke kakhulu.
Eyona nto ichazwa ngumlinganiseloungakanani umgaqo weenqwelo-moya isikrufu ekufuneka senze umsebenzi waso. Ukutya, ukunyibilika, kunye nokulinganisa konke kwenzeka ngolo hlobo. Ubude obuninzi buthetha amandla amaninzi okunyibilika kunye nokuxuba ngakumbi. Ubude obuncinane buthetha ngaphantsi kokubini, kunye nexesha elincinane lokuba impahla ihlale ishushu.
Uninzi lwezikrufu zesitofu zihlala phakathi kwe 18:1 kunye ne 25:1, kunye no 20:1 ukuya ku 22:1 umhlaba oqhelekileyo koomatshini benjongo jikelele. Isikhokelo sentsika sigubungela umfanekiso opheleleyo wethuisikrufu sokubumba umbhobho sikhokelo.
Kutheni Isitofu i-L/D Imfutshane kune-Extrusion L/D
I-Extruders idla ngokuqhuba i-25:1 ukuya ku-33:1. Izikrufu zokutofa zihlala zifutshane, kwaye isizathu ngumjikelo, hayi isiko.
Isikrufu se-extruder sijikeleza ngokuqhubekayo. Izinto eziphathekayo zingena kwelinye icala, zidlule, kwaye zishiya kwelinye. Akukho nto ilindileyo.
Isikrufu sokutofa sisebenza ngokugqabhuka. Iyajikeleza ukwenza iplastikhi isitofu esinye, irhoxile, emva koko ime. Iyatofa, kwaye ukungunda kuyaphola. Ngalo lonke elo xesha, inyibilika esele ikwi-barrel ihleli kwaye ihlala ishushu.
Oko kulinda ngumahluko wonke. Umphanda omde ubamba ukunyibilika okuthe chatha, kwaye kumatshini wokutofa, ukunyibilika okuninzi kuthetha izinto ezininzi ezilindileyo kwimijikelo emininzi. Kwi-resin evakalelwa ngubushushu, ubude obongezelelweyo abukho umthamo owongezelelweyo. Yimbali eyongezelelweyo ye-thermal.
Ke uyilo loyilo lwenaliti lulinganisa umthamo wokunyibilika ngokuchasene nexesha lokuhlala, ngelixa i-extrusion ubukhulu becala ithenga nje umthamo wokunyibilika.
Into ekungekho mntu ukuxelela yona: Awunako ukuyitshintsha i-L/D
Amanqaku malunga L / D intetho ngokungathi ufumana ukukhetha inombolo. Kumatshini osele ungowakho, awunawo.
L ilungiswa ngumphanda.Umbhobho sisitya soxinzelelo somatshini esibotshelelwe kwisakhelo somatshini, kunye neendawo zaso zesifudumezi, umqala wokutya, kunye nokunyuka konke kwakhiwe malunga nobude obunye. Akukho mntu wenza umphanda omde.
Ke okukuphela koguquko olushiyekileyo kwi-L/D ngu-D, i-diameter ye-screw. Guqula i-diameter, kwaye umlinganiselo utshintsha kunye nayo, kuba ubude obungaphezulu komgca abuyi kuhamba.
Yiyo loo nto abakhi bomatshini badwelisa ezimbini okanye ezintathu iidiameter ezijijwa kumatshini omnye. Abakuniki iisayizi ezintathu zokudubula. Bakunika amanqaku amathathu kwi-curve yorhwebo, kwaye ubungakanani bokudubula yenye yezinto ezihambayo.
I-Screw Diameter: I-Lever ehambisa yonke into
Kwi-barrel esisigxina, ukhetho olulodwa luhambisa izinto ezine ngexesha elinye. Qonda le theyibhile kwaye uyayiqonda inaliti L/D.
| Ukuba ukhetha i... | Idayamitha yesikrufu esincinci | Idayamitha yesikrufu esikhulu |
|---|---|---|
| Umlinganiselo we-L/D | Phezulu(omnye u-L, omncinci D) | Ngasezantsi(omnye u-L, mkhulu D) |
| Shot umthamo | Encinci(umthamo omncinci kwi-mm nganye ye-stroke) | Enkulu |
| Uxinzelelo lwesitofu lukhona | Phezulu(amandla afanayo kwindawo encinci) | Ngasezantsi |
| Umthamo wokunyibilika ngokudubula | Ngcono(i-L/D eninzi malunga nemathiriyeli encinci) | Unesisa esingaphantsi |
| Ixesha lokuhlala kwinxalenye ethile | Mfutshane(ukudubula kusebenzisa umphanda omncinci) | Ixesha elide |
| Iisuti | Amacandelo amancinci achanekileyo, iindonga ezincinci, i-viscosity ephezulu kunye ne-resins-sensitive resins | Iishothi ezinkulu, iireyini zentengiso, amacandelo ashinyeneyo |
Funda umqolo woxinzelelo kwakhona, kuba ithatha isigqibo semisebenzi emininzi kunokuba abantu balindele. I-hydraulic yomatshini okanye idrayivu yombane ihambisa amandla asisigxina ngasemva kwesikrufu. Uxinzelelo ngamandla ohlulwa ngokwendawo. Isikrufu esincinci sinendawo yobuso obuncinci, ngoko ke amandla afanayo avelisa uxinzelelo oluphezulu lokunyibilika.
Yiyo loo nto umsebenzi wodonga olucekethekileyo kunye ne-viscosity ephezulu uhlala uhlala kwi-screw encinci: inokutyhala inyibilike ibe ngumngxuma oqinileyo esingakwaziyo ukuzalisa isikrufu esikhulu. I-L / D ephezulu ehamba nayo ibhonasi, kungekhona into eyenzekayo.
Kwaye ufunde umqolo wokuhlala. Yeyona ithatha isigqibo ngokuthula ukuba iPC yakho ityheli.
Indlela i-L/D echaphazela ngayo ubungakanani beShot
Ngokungqongqo, i-L/D ayibeki ubungakanani bokudubula. I-diameter kunye ne-stroke yenza: umthamo wokudubula yindawo ye-screw-sectional iphindaphindwe ngokuba ihambe kangakanani.
Kodwa kumatshini wokwenyani awukwazi ukuwahlula, kuba idiameter efanayo ebeka ukudubula kwakho ikwaseta i-L/D yakho. Khetha isikrufu esincinci kwinxalenye encinci echanekileyo, kwaye ukhethe i-L / D ephezulu ngaxeshanye.
Umphumo oluncedo uyavuyisa. Isikrufu esikunika isithonga esincinci sikwakunika ubude bokunyibilika ngakumbi ngegram nganye yezinto kunye noxinzelelo oluphezulu lwenaliti. Ezo zakhiwo zintathu zihambelana nemisebenzi efanayo, yiyo loo nto urhwebo lusebenza ngokucocekileyo rhoqo.
Apho iyeka ukonwaba kuxa unyanzela inxalenye kwisikrufu esingalunganga. Qhuba isithonga esincinci kakhulu kwi-screw ye-diameter enkulu kwaye ufumana eyona nto imbi kuzo zombini: i-L/D ephantsi, umthamo omkhulu womphanda xa uthelekiswa nokudubula kwakho, kunye nezinto ezijikeleza ubushushu ixesha elide kakhulu.
Ixesha lokuHlala: Umbulali osemgangathweni onokuthi ubale
Ixesha lokuhlala lelokuba iqhekeza elinikiweyo lepolymer lihlala lishushu kangakanani ngaphakathi komphanda phambi kokuba litofwe. Lelona nani liphantsi kakhulu ekubumbeni inaliti, kwaye ungaliqikelela kwimizuzwana engamashumi amathathu.
Ixesha lokuhlala ≈ (umthamo wokudubula komphanda ÷ ubungakanani bakho bokudubula) × ixesha lomjikelo
Zombini izakhono kwiiyunithi ezifanayo. Thatha umthamo wokudubula kwireyithingi yomatshini.
Yenza umzekelo. Umatshini onikwe i-200 g yomthamo wokudutyulwa, osebenzisa i-20 g inxalenye kumjikelo wemizuzwana engama-30. Umlinganiselo yi-10, ngoko ke inyibilika ihlala malunga nemijikelo elishumi. Ixesha lokuhlala limalunga nemizuzwana engama-300, okanye imizuzu emihlanu.
Imizuzu emihlanu kwiqondo lobushushu lokunyibilika lixesha elide lePC, iPOM, iPET, okanye iPVC. Akukho nto malunga neesetingi zakho engalunganga. Inxalenye incinci kakhulu kumbhobho, kwaye impahla iyapheka ngelixa ilinde ixesha layo.
Ngoku susa loo msebenzi kwisikrufu esincinci. Umthamo wokudubula wehla ukuya, yithi, 80 g. Kwaloo 20 g inxalenye ngoku isebenzisa ikota yomphanda, inyibilika ihlala kwimijikelo emine endaweni yeshumi, kwaye ixesha lokuhlala liwela malunga nemizuzu emibini.
Awutshintshanga indawo yokumisela. Utshintshe i-screw diameter, kwaye ingxaki yokuthotywa ihamba nayo.
I-20–80% yeBhanti yoMmandla wokuShot
Isikhokelo soshishino esikhankanywa ngokuqhelekileyo kukugcina ukudubula kwakho kwindawo ethile phakathi kwe-20% kunye ne-80% yomthamo olinganisiweyo wokudubula womatshini. Qinisekisa ibhanti ngokuchasene nencwadana yemigaqo yomatshini wakho, kodwa ingqiqo emva kwayo ibambe yonke indawo.
Ngaphantsi kwebhendi, ixesha lokuhlala lihamba ixesha elide. Izinto eziphathekayo zenza iihambo ezininzi kakhulu ngenxa yobushushu, kwaye ii-resin ezingevayo kubushushu ziyancipha. Oku kukungaphumeleli kwefomyula engentla yokubambisa.
Ngaphezulu kwebhendi, izinto ezimbini ziyaphuka. Akukho mphanda waneleyo oseleyo wokubamba umqamelo ofanelekileyo, ke ngoko ukupakisha kufumana ukudutyulwa okungahambelaniyo. Kwaye isikrufu sinexesha elincinane kunye nobude bokunyibilikisa umphanda ophantse wagcwala wezinto, ngoko ke umgangatho wokunyibilika uyachaphazeleka kanye xa ubuza uninzi lwayo.
Umhlaba phakathi kwebhendi kwaye umatshini unendawo yokusebenza. Ukuba inxalenye yakho ihleli ngaphandle kwayo, ukulungiswa okuchanekileyo yi-diameter ye-screw ehlukeneyo, okanye umatshini owahlukileyo, kungekhona isethi yobuqhawe yezicwangciso zenkqubo.
