Iintlobo ezi-5 zePlastiki yokuBunjwa kuBavelisi beeMveliso zePlastiki zesiNtu

Kukho iintlobo ezimbini zeplastiki: Thermoplastic kunye ne-thermo-rigid. I-Thermoplastics iyanyibilika kwaye i-thermoplastic ayikho. Umahluko kwindlela iipolymers zenziwa ngayo. Iipolymers, okanye imixokelelwane yee-athomu, zifana neentambo ezinomlinganiselo omnye kwi-thermoplastics, kwaye ukuba ziyanyibilika, zinokuthatha isimo esitsha. Kwi-thermo-rigid bangamanethiwekhi amathathu-dimensional ahlala egcina imilo yawo. Iintlobo ngeentlobo zeenkqubo zisetyenziselwa ukwenza okanye ukubumba iiplastiki, ezinye zisebenza kuphela kwi-thermoplastics, ezinye kuphela ze-thermo-rigid kwaye ezinye iinkqubo zikhonza zombini.

I-extrusion

I-Extrusion yinkqubo yokubumba eqala ngeplastiki "eluhlaza" efana neegranules, umgubo, okanye iiperile. Ihopper yondla iplastiki kwigumbi elijikelezayo. Igumbi, elibizwa ngokuba yi-extruder, liyaxuba kwaye linyibilikise iplastiki. Iplastiki enyibilikisiweyo inyanzeliswa ngaphandle ngokufa kwaye ithatha ubume bemveliso egqityiweyo. Into iwela kwibhanti yokuhambisa apho ipholiswe khona ngamanzi kwaye inqunywe. Ezinye iimveliso ezinokuthi zenziwe nge-extrusion ziquka amaphepha, ifilimu kunye neetyhubhu.

Ukufakelwa kwe-injection

Ukufakelwa kwe-injection isebenzisa umgaqo ofanayo njenge-extrusion. Iplastiki ekrwada ityiswa ukusuka kwi-hopper ukuya kwigumbi lokufudumeza. Nangona kunjalo, endaweni yokunyanzelwa ukuba idlule kwi-die, inyanzeliswa kwi-mold ebandayo phantsi koxinzelelo oluphezulu. Iplastiki iyaphola kwaye yomelele, kwaye imveliso iyacocwa kwaye igqitywe. Ezinye iimveliso ezenziwe ngesitofu ziquka ukupakishwa kwebhotolo, iminqwazi yeebhotile, izinto zokudlala kunye nefenitshala yegadi.

Ukubetha kokubumba

Ukubumba ukuvuthela kusebenzisa inaliti yomoya emva kokuba iplastiki ikhutshiwe okanye yatofwa. I-Extrusion blow blowing isebenzisa idiyizi eyenza ityhubhu yeplastiki eshushu kunye nokungunda okupholileyo ngeenxa zonke. Umoya ocinezelweyo utofwa ngetyhubhu ukunyanzela iplastiki ukuba ithathe ubume bomngundo. Oku kuvumela abavelisi ukuba benze iimilo eziqhubekayo kunye nezifanayo ezingenanto, kodwa kufuneka batofe isitofu ngasinye kubo. Isitofu-ukuvuthela sisebenzisa isitofu sokungunda, kodwa endaweni yokufumana imveliso egqityiweyo, ukungunda linyathelo eliphakathi apho iplastiki ifudunyezwa ukuze ivuthelwe kwimo yayo yokugqibela kubumba obubandayo obahlukileyo.

Ucinezelo yokubumba

Ukubumba ukunyanzeliswa yinkqubo yokuthatha umthamo ochazwe kwangaphambili weplastiki, uyibeke kwi-mold, kwaye usebenzise enye i-mold ukuyityumza okanye ukuyicinezela kwi-mold yokuqala. Inkqubo ingaba ngokuzenzekelayo okanye i-manual kwaye ifanelekile kwizinto zombini ze-thermoplastic kunye ne-thermo-rigid.

I-Thermoformed

I-Thermoforming yinkqubo yokufudumeza ifilimu yeplastiki ngaphandle kokuyinyibilika, ukuyithambisa ngokwaneleyo ukuba ithathe ifom yokubumba ecinezelwe kuyo. Umenzi wenza iplastiki ithathe imo efunwayo isebenzisa uxinzelelo oluphezulu, i-vacuum okanye isikhunta sendoda. Emva kokuba imveliso egqityiweyo ipholile, iyasuswa kwi-mold kwaye iintsalela zihlaziywa ukuze zisetyenziswe kwifilimu entsha.

Inkqubo yokubumba inaliti yeplastiki

Isitofu sokubumba yenye yeendlela eziphambili zokwenza iplastiki. Inyathelo lokuqala kwinkqubo yokubumba yokutofa kukutyisa iigranule zeplastiki kwihopha, ethi ke yondle iigranules kwicylinder. Umphanda uyafudunyezwa kwaye unesinye isikrufu okanye isitofu senkunzi yegusha. Esinye isikrufu siqhele ukufunyanwa koomatshini abavelisa iindawo ezincinci. I-screw ephindaphindayo ityumza i-granules, yenza kube lula ukuba iplastiki ifakwe ulwelo. Ukuya ngaphambili kombhobho, isikrufu esibuyiselanayo siqhubela phambili iplastiki enyibilikisiweyo, sitofe iplastiki ngombhobho nakwingundo engenanto. Ngokungafaniyo nebhere, ukungunda kugcinwa kubanda ukwenza lukhuni iplastiki ibe yimo echanekileyo. Iipleyiti zokubumba zibanjwe zivaliwe ngeplate enkulu (ekubhekiselwa kuyo njengeplate ehambayo). Ipleyiti ehambayo idityaniswe kwipiston ye-hydraulic, eyenza uxinzelelo kwi-mold. Ukucinywa okuvaliweyo kokungunda kweplastiki kuyithintela ukuba ingaphumi, nto leyo eya kudala ukonakala kwiindawo ezigqityiweyo.
