ISikhokelo seNyathelo ngeNyathelo kwiNkqubo yokuBumba isitofu se-ABS

I-Acrylonitrile Butadiene Styrene (ABS) yenye yeepolymers ze-thermoplastic ezisetyenziswa kakhulu kwimveliso yanamhlanje. Iyaziwa ngokuqina kwayo, ukuxhathisa impembelelo, kunye nokulula ukusetyenzwa, i-ABS yimathiriyeli yokuzikhethela kumashishini angenakubalwa, ukusuka kwiimoto ukuya kwii-elektroniki zabathengi. Phakathi kweendlela ezininzi zokuvelisa ezikhoyo,Ukubumba inaliti ye-ABSibalasele njengeyona ndlela isebenzayo kunye neyongezelekayo yokuvelisa izinto zeplastiki ezomeleleyo.

Kweli nqaku, siza kubonelela aIsikhokelo senyathelo ngenyathelo kwinkqubo yokubumba inaliti ye-ABS, kukunceda uqonde ukuba izinto ze-ABS ezikrwada ziguqulwa njani zibe ziimveliso ezigqityiweyo ezikumgangatho ophezulu.

Inyathelo 1: Ukulungiselela Izinto

Inkqubo iqala ngokulungiselela i-ABS resin ngendlela yeepellets ezincinci. Ezi pellets zinokuqulatha izongezo, ezinje ngemibala, i-UV stabilizers, okanye i-flame retardants, kuxhomekeke kwisicelo. Ngaphambi kokubunjwa kwenaliti, iipeliti ze-ABS zihlala zomiswa ukususa nakuphi na ukufuma. Eli nyathelo libalulekile kuba ukufuma okugqithisileyo kunokubangela iziphene ezinjengamaqamu okanye amabala abuthathaka kwimveliso yokugqibela.

Inyathelo lesi-2: Ukutya kunye nokunyibilikisa iiPellet ze-ABS

Xa zomisiwe, iipellet ze-ABS zilayishwa kwi-hopper yomatshini wokubumba inaliti. Ukusuka apho, iipellets zihamba ziye kwi-barrel eshushu apho isikrufu esijikelezayo sityhala kwaye sinyibilike. I-ABS ineqondo lokushisa elinyibilikayo malunga ne-200-250 ° C, kwaye ukugcina iphrofayili yokushisa echanekileyo kuqinisekisa ukuba izinto zihamba kakuhle ngaphandle kokuthotywa.

Inyathelo lesi-3: Isitofu kwi-Mold

Xa izinto ze-ABS zifikelela kwi-viscosity efanelekileyo, ifakwe phantsi koxinzelelo oluphezulu kwintsimbi okanye i-aluminium mold. Lo ngundo uyilwe ngemingxuma echanekileyo eyenza imilo echanekileyo yendawo oyifunayo. Isigaba sokutofa kufuneka silawulwe ngononophelo ukuphepha imiba efana neeshot ezimfutshane (ukuzaliswa okungaphelelanga) okanye i-flash (ukuvuza kwezinto ezigqithisileyo).

Inyathelo lesi-4: Ukupholisa kunye nokuqinisa

Emva kokuba i-mold izaliswe, izinto ze-ABS ziqala ukupholisa kwaye ziqiniswe ngaphakathi kwendawo. Ukupholisa sesinye sezona zigaba zibalulekileyo kwinkqubo kuba kuchaphazela ngokuthe ngqo amandla enxalenye, ukugqiba komphezulu, kunye nokuchaneka komda. Ixesha lokupholisa linokwahluka ngokuxhomekeke kubukhulu kunye nobukhulu benxalenye, kodwa abavelisi bakholisa ukusebenzisa amajelo okupholisa alungiselelweyo ekubumbeni ukukhawulezisa eli nyathelo.

Inyathelo lesi-5: Ukukhutshwa kweCandelo

Nje ukuba iplastiki ye-ABS ipholile kwaye yomelele, ukungunda kuyavuleka, kwaye izikhonkwane ze-ejector zityhala indawo egqityiweyo ngaphandle komngxuma. Inkqubo yokukhupha kufuneka ilawulwe ngononophelo ukuthintela ukukrwela okanye ukonakalisa icandelo. Kweli nqanaba, inxalenye sele ifana nemveliso yokugqibela, kodwa ukugqitywa okuncinci kusenokufuneka.

Inyathelo lesi-6: Emva kokwenziwa komsebenzi kunye nokuHlolwa koMgangatho

Emva kwe-ejection, inxalenye ye-ABS inokuhamba ngeendlela ezongezelelweyo ezifana nokucheba izinto ezingaphezulu, ukuthungwa komphezulu, okanye ukupeyinta. Kwiimveliso eziphezulu, abavelisi banokusebenzisa iinkqubo zesibini ezifana ne-ultrasonic welding okanye i-chrome plating. Ilungu ngalinye liyahlolwa ukuqinisekisa ukuba liyahambelana nemigangatho yomgangatho wemilinganiselo, amandla, kunye nenkangeleko yomphezulu.

Inyathelo 7: Ukupakishwa kunye nokuhanjiswa

Ekugqibeleni, iindawo ze-ABS ezigqityiweyo ziyapakishwa kwaye zilungiselelwe ukuthunyelwa. Ngokuxhomekeke kwiimfuno zomthengi, iinxalenye zinokuhanjiswa njengezinto ezizimeleyo okanye zidityaniswe kwiimveliso ezinkulu.

Kutheni Khetha Ukubumba Isitofu se-ABS?

IInkqubo yokubumba inaliti ye-ABSinika iingenelo ezininzi:

Ukuchaneka okuphezulu kunye nokuhambelana: Ilungele imveliso yobuninzi yamalungu afanayo.

Ukuguquguquka kwezinto: I-ABS inokuguqulwa kunye nezongezo zokuphucula iimpawu.

Ukusebenza kweendleko: Emva kokuba isikhunta senziwe, umthamo omkhulu unokuveliswa ngexabiso eliphantsi.

Usetyenziso olubanzi: Ukusuka kwiideshibhodi zeemoto ukuya kwizindlu ze-smartphone, ukubumba inaliti ye-ABS ixhasa amashishini amaninzi.

Iingcamango Zokugqibela

IUkubumba inaliti ye-ABSinkquboyindlela ethembekileyo neyoyikisayo yokwenza iinxalenye zeplastiki ezomeleleyo, ezikhaphukhaphu, kunye nobuhle obukholisayo. Ngokuqonda inyathelo ngalinye-ukusuka ekulungiseleleni izinto ukuya ekuhlolweni kokugqibela-abavelisi kunye nabaqulunqi beemveliso banokuqonda ngcono ukuba kutheni i-ABS ihlala ilukhetho oluphezulu kwihlabathi lokubumba inaliti yeplastiki.
