Njengoba kwaziwa, isetshenziswa kakhulu emishinini yokubumba yepulasitiki, njengama-extruders ephrofayili epulasitiki, imishini yokubumba umjovo, njll. Induku yomucu nomgqomokabushac izingxenye zensimbi zezinto zokwakha zepulasitiki. Yingxenye eshiselwayo, ekhishwayo, futhi eyenziwe ngepulasitiki.
Iwumgogodla wemishini yepulasitiki. Izikulufu zisetshenziswa kabanzi ezikhungweni zokucupha, imishini ye-CNC, izinsimbi ze-CNC, imishini yokubumba umjovo, ukusika izintambo, imishini yokugaya, imishini yokugaya, izintambo ezihamba kancane, izintambo ezisheshayo, imishini yokumba ye-PCB, imishini yokuqopha ngokunemba, imishini yokuqopha neyokugaya, izinjini zokukhipha inhlansi, imishini yokuluma amazinyo, amapulani, imishini yokugaya i-gantry emikhulu eqondile, njalonjalo.
Izimbangela eziyinhloko zokuguga zimi kanje:
1. Uhlobo ngalunye lwepulasitiki lunobubanzi obufanele bokucubungula ukushisa kwe-plasticizing, futhi izinga lokushisa lokucubungula lomgqomo wezinto ezibonakalayo kufanele lilawulwe ukuze lisondele kulolu banga lokushisa. Ipulasitiki eyimbudumbudu ingena emgqonyeni isuka ku-hopper futhi iqale ifinyelele esigabeni sokuphakela, lapho ukungqubuzana okomile kwenzeka ngokungenakugwenywa. Uma lezi pulasitiki zingashisi ngokwanele futhi zincibilika ngokungalingani, kulula ukubangela ukuguga okukhulayo odongeni lwangaphakathi lombhobho kanye nobuso besikulufu. Ngokufanayo, ezigabeni zokucindezelwa kanye ne-homogenization, uma isimo sokuncibilika sepulasitiki siphazamiseka futhi singalingani, kuzophinde kubangele ukugqoka okusheshayo.
2. Ijubane kufanele lilungiswe ngendlela efanele. Ngenxa yokwengezwa kwama-ejenti aqinisayo afana ne-fiberglass, amaminerali, noma ezinye izigcwalisi kwamanye amapulasitiki. Lezi zinto zivame ukuba namandla amakhulu okungqubuzana ezintweni zensimbi kunepulasitiki encibilikisiwe. Lapho ujova lawa mapulasitiki, uma kusetshenziswa isivinini esikhulu sokujikeleza, ngeke nje kwandise amandla okugunda epulasitiki, kodwa futhi kukhiqize imicu eyengeziwe edabukile ukuze kuqiniswe. Imicu edabukile iqukethe iziphetho ezibukhali, okwandisa kakhulu amandla okugqoka. Lapho amaminerali angaphili eshelela ngesivinini esikhulu ezindaweni zensimbi, umphumela wawo wokukhuhla nawo ubalulekile. Ngakho isivinini akufanele silungiswe sibe phezulu kakhulu.
3. Isikulufu sizungeza ngaphakathi komgqomo, futhi ukungqubuzana phakathi kwezinto kanye nalokhu kokubili kubangela ukuthi indawo yokusebenza yesikulufu nomgqomo iguge kancane kancane: ububanzi besikulufu buyancipha kancane kancane, futhi ububanzi bomgodi ongaphakathi womgqomo buyanda kancane kancane. . Ngale ndlela, igebe le-diameter elifanelekile phakathi kwesikulufa kanye nomgqomo liyakhula kancane kancane njengoba liguga kancane kancane. Kodwa-ke, ngenxa yokumelana okungaguquki kwekhanda lomshini kanye nepuleti le-splitter phambi komgqomo, lokhu kukhulisa izinga lokugeleza lokuvuza kwezinto ezikhishwe lapho kuthuthukiswa, okungukuthi, izinga lokugeleza lempahla ukusuka kugebe lobubanzi kuya ekudleni. isiqondiso siyanda. Ngenxa yalokho, ukukhiqizwa kwemishini yepulasitiki kwehlile. Lesi senzakalo kwandisa isikhathi sokuhlala sezinto emgqonyeni, okubangela ukubola kwempahla. Uma kuyi-polyvinyl chloride, igesi ye-hydrogen chloride ekhiqizwa ngesikhathi sokubola ithuthukisa ukugqwala kwesikulufu nomgqomo.
4. Uma kukhona okokugcwalisa okufana ne-calcium carbonate kanye ne-glass fiber ku- material, kungasheshisa ukuguga kwesikulufu nomgqomo.
5. Ngenxa ye-plasticization engalingani yento noma ukuxutshwa kwezinto zensimbi zangaphandle entweni, i-torque yesikulufu iyanda ngokuzumayo, edlula umkhawulo wamandla wesikulufu futhi ibangele ukuthi isikulufu siphuke. Lolu wuhlobo lokulimala kwengozi okungajwayelekile.
