Ibikoresho bisanzwe byo gukuramo
Ibikoresho bitandukanye bikoreshwa mugikorwa cyo gukuramo. Hano turashobora gufata urugero rwibikorwa bya PVC. Ibindi bikoresho ni polyethylene, acetal, nylon, acrylic, polypropilene, polystirene, polyakarubone, na acrylonitrile. Nibikoresho byibanze bikoreshwa mugikorwa cyo gukuramo. Ariko, inzira ntabwo igarukira gusa kubikoresho.
Ubumenyi bwibanze bwauburyo bwo gukuramo plastike
Inzira yo gukuramo plastike izatangirana no guhindura resin mbisi. Ubwa mbere, shyira muri hopper ya extruder. Iyo resin idafite inyongeramusaruro kuri progaramu zimwe zihariye, inyongera zongerwaho muri hopper. Nyuma yo gushyirwa, resin igaburirwa kuva ku cyambu cyo kugaburira hopper, hanyuma ikinjira muri barri ya extruder. Hano hari akayunguruzo kazunguruka. Ibi bizagaburira resin, izagenda muri barrale ndende.
Muri iki gikorwa, resin ihura nubushyuhe bwinshi. Ubushyuhe bukabije burashobora gushonga ibikoresho. Ukurikije ubushyuhe bwa barrale nubwoko bwa thermoplastique, ubushyuhe burashobora gutandukana kuva kuri dogere 400 kugeza 530 Fahrenheit. Byongeye kandi, extruders nyinshi zifite akabari kongerera ubushyuhe kuva gupakira kugeza kugaburira gushonga. Inzira yose igabanya ibyago byo kwangirika kwa plastike.
Plastike yashonga ikagera kumpera ya barriel, aho yakandamizwaga kumuyoboro wibiryo na filteri hanyuma amaherezo igapfa. Mugihe cyo gukuramo, ecran zizakoreshwa mugukuraho umwanda muri plastiki yashongeshejwe. Umubare wa ecran, ububobere bwa ecran nibindi bintu bimwe na bimwe bigenzurwa kugirango bishonge kimwe. Byongeye kandi, igitutu cyinyuma gifasha gushonga kimwe.
Ibikoresho bishongeshejwe bimaze kugera mu biryo, bizagaburirwa mu cyuho. Hanyuma, birakonje kandi bigakomera gukora ibicuruzwa byanyuma. Plastiki ikozwe vuba ifite ubwogero bwamazi bufunze kugirango byihute. Ariko, mugihe cyo gukuramo impapuro, ubwogero bwamazi buzasimbuzwa imizingo ikonje.
Intambwe nyamukuru yauburyo bwo gukuramo imiyoboro ya pulasitike
Nkuko byavuzwe haruguru, uburyo bwo gukuramo plastike butanga ibicuruzwa bitandukanye bitandukanye kuva ibikoresho byubaka kugeza ibice byinganda, ibigo byamashanyarazi, amakadiri yidirishya, inkombe, ikirere hamwe nuruzitiro. Ariko, inzira yo gukora ibyo bicuruzwa bitandukanye izaba imwe hamwe nibitandukaniro bike. Hariho uburyo bwinshi bwo kwinjiza imiyoboro ya plastike.
Mgushonga
Ibikoresho bibisi birimo granules, ifu cyangwa granules bizashyirwa muri hopper. Nyuma yibyo, ibikoresho bigaburirwa mucyumba gishyushye cyitwa extruder. Ibikoresho bishonga uko inyura muri extruder. Extruders ifite bibiri cyangwa imwe ya swivel.
Akayunguruzo
Ibikoresho bimaze gushonga, inzira yo kuyungurura izatangira. Ibikoresho byashongeshejwe bizatemba biva mu muhogo unyuze mu muhogo bigana ku cyuma kizunguruka gikora imbere muri extruder. Imashini izunguruka ikora muri barrique itambitse aho ibikoresho bishongeshejwe bizungururwa kugirango ubone guhuza.
Kugena Ibipimo by'ibikoresho byashongeshejwe
Imiterere yibikoresho bya pulasitike biratandukanye bitewe nibikoresho fatizo bikoreshwa mugikorwa. Nyamara, ibikoresho byose bibisi bivurwa nubushyuhe. Ibi bikoresho bizagerwaho nubushyuhe bukabije kubushyuhe bwihariye. Urwego rw'ubushyuhe ruzahinduka bitewe nibikoresho fatizo. Mugihe cyo kurangiza inzira, plastiki yashongeshejwe izasunikwa no gufungura bita mold. Ihindura ibikoresho mubicuruzwa byanyuma.
Pgutunganya
Muri iyi ntambwe, gupfa gukata umwirondoro bizashirwaho kugirango bigende neza kandi byoroshye kuva kuri silindrike ya profili ya extruder kugeza kumiterere yanyuma. Twabibutsa ko kugirango tubone ibicuruzwa byizewe kandi byujuje ubuziranenge, guhora kwa plastike ni ngombwa cyane.
Mgukonjesha
Plastike izakurwa mubibumbano hanyuma inyurwe mumukandara kugirango ikonje. Ubu bwoko bw'umukandara bwitwa umukandara. Nyuma yiyi ntambwe, ibicuruzwa byanyuma bikonjeshwa namazi cyangwa umwuka. Birakwiye ko tuvuga ko inzira izasa no guterwa inshinge. Ariko itandukaniro ni uko plastiki yashongeshejwe ihindurwamo ifu. Ariko mugutera inshinge, inzira ibaho binyuze mubibumbano.
