Ingongoma Ephambili Yokuqala: Ukuphatha Izinto – “Ukomisa yindlela yokuphila”

Eli lelona nyathelo lokuqala libalulekileyo. Ubungakanani obuncinci be-ABS buyanele ukonakalisa yonke imveliso.

Kufuneka yomiswe kakuhle: Amasuntswana e-ABS aya kufunxa umswakama ovela emoyeni ngexesha lokugcina nokuthuthwa. Ngaphambi kokubumba ngenaliti, kufuneka kusetyenziswe isixhobo sokomisa esisusa umswakama ukuze somise rhoqo kubushushu obuyi-80-85℃ kangangeeyure ezi-2-4. Ayinakutshintshwa nje nge-oven eqhelekileyo yomoya oshushu.

Isiphumo: Ukomiswa okungaphelelanga kunokukhokelela kwimigca yesilivere (imisonto yesilivere), amaqamza, umphezulu onkungu, kunye nokuwohloka kwezinto kumphezulu wemveliso, okubangela ukuncipha okukhulu kwamandla.

Isigwebo: Indlela elula yokuqinisekisa kukwenza "inaliti yomoya". Ukuba umcu wezinto ezinyibilikisiweyo ofakwe kwimpumlo uthambile kwaye ukhanya, ngaphandle kwamaqamza okanye izandi eziqhekekayo, oko kubonisa ukuba isiphumo sokomisa silungile.

Ingongoma Ephambili Yesibini: Inkqubo Yokubumba Ngenaliti – “Ulawulo Lobugcisa”
Iiparameter zenkqubo "ziivili zokuqhuba" zokulawula umgangatho wemveliso. Ifestile yenkqubo ye-ABS ibanzi kakhulu, kodwa ukuchaneka kumisela umgangatho.

Ulawulo lobushushu

Ubushushu bebhareli: Ububanzi obuqhelekileyo bobushushu bokucubungula i-ABS yi-190-250℃. Kucetyiswa ukuba uyibeke kwiindawo ukusuka ngasemva ukuya phambili ukuze uphephe amaqondo obushushu aphezulu kakhulu.

Icandelo elingasemva (indawo yokondla): 160-180℃ (Ukuthintela ukugabha kwindawo evulekileyo yehopper)

Icandelo eliphakathi (indawo yoxinzelelo): 180-220℃ (indawo ephambili yokwenza iplastiki)

Icandelo elingaphambili (indawo yokulinganisa): 210-240℃ (ukuqinisekisa ukuba inyibilika ngokulinganayo)

Ubushushu bomlomo: 200-230℃ (ingaphantsi kancinci kunecandelo elingaphambili ukuthintela ukuvuza kwamathe)

Ubushushu bomngundo: Ubushushu bomngundo bunempembelelo enkulu kwinkangeleko kunye noxinzelelo lwangaphakathi lweemveliso ze-ABS. Kucetyiswa ukuba ubushushu bomngundo bulawulwe phakathi kwama-50 nama-80 degrees Celsius.

Iingenelo zobushushu obuphezulu bokungunda (60-80℃):

Yandisa ukukhanya komphezulu, yenza iindawo zibe zikhazimle ngakumbi, kwaye ube nobuchule obunamandla bokuphinda iinkcukacha zomphezulu wesikhunta.

Nciphisa umgca wokuwelda, yenza umgca wokuwelda ungacaci kwaye ube namandla aphezulu.

Kunciphisa kakhulu uxinzelelo lwangaphakathi, kuphucula uzinzo olulinganayo lwamalungu kunye nokumelana kwawo nokuqhekeka koxinzelelo lokusingqongileyo.

Iingxaki zobushushu obuphantsi bokungunda (<50℃): Kungakhokelela ekukhanyeni komphezulu okungekuhle, amanqaku okuwelda acacileyo, uxinzelelo olukhulu lwangaphakathi, kunye nokwanda kobuthathaka bemveliso.

Uxinzelelo kunye nesantya

Isantya sokujova: Isantya esiphakathi okanye esiphezulu sokujova sidla ngokusetyenziswa ukufikelela kumphezulu okhanyayo. Nangona kunjalo, ukuba isantya sikhawuleza kakhulu, sinokubangela imicu yejethi (ukunyibilika kokudubula kumgodi njengenyoka) okanye igesi evalelekileyo. Kwiindawo ezintsonkothileyo okanye ezinodonga oluncinci, ulawulo lokujova olunamanqanaba amaninzi "olucothayo-olukhawulezayo-olucothayo" lungasetyenziswa.

Ukubamba uxinzelelo kunye nobude bexesha: Le yeyona nto iphambili ekulawuleni ukuncipha (ukudandatheka).

Uxinzelelo lokubamba: Ngokwesiqhelo yi-50% ukuya kwi-80% yoxinzelelo lokujova. Uxinzelelo lokubamba olwaneleyo kufuneka lufakwe ukuze kulungiswe ukuncipha kweplastiki ngexesha lokupholisa.

Ixesha loxinzelelo lokubamba lixhomekeke kakhulu kwixesha lokubanda kwesango. Ixesha elifutshane kakhulu linokubangela ukufinyela kwangaphakathi (ukuncipha) kwemveliso, ingakumbi kwimisipha nakwiindawo ezixineneyo. Ukuba ixesha lide kakhulu, liya kwandisa uxinzelelo lwangaphakathi, linciphise ukuqina kwaye lichithe umjikelo. Kufuneka liphuculwe ngokuziqhelanisa.

Ingongoma Ephambili Yesithathu: Uyilo Lwesikhunta – “Iinkcukacha Zimisela Impumelelo okanye Ukusilela
Isikhunta simisela ngokuthe ngqo imo, inkangeleko kunye nokuchaneka kwamalungu.

Uyilo lwesango: Khetha ngokusekelwe kwiimfuno zembonakalo yemveliso. Kwiindawo ezineemfuno zembonakalo ephezulu, iigeyithi ezifihlakeleyo okanye ii-needle valve hot runners zingasetyenziswa ukuze kufunyanwe iimpawu zesango ezintle nezithandekayo.

Inkqubo yokukhupha umoya: Ukukhupha umoya okwaneleyo kubalulekile. Ukukhupha umoya ongemhle kunokukhokelela kwiziphene ezifana nokutsha (imivimbo emdaka okanye emnyama ebonakala kumphezulu weendawo) kunye nokuzaliswa okungaphelelanga. Izithuba zokukhupha umoya zihlala zikwindawo yokuhlukana kunye nendawo yokungena, enobunzulu obuyi-0.02 ukuya kwi-0.03mm.

Inkqubo yokupholisa: Ukupholisa okufanayo nokusebenzayo kubaluleke kakhulu. Ukupholisa okungalinganiyo kunokubangela ukugoba nokuguquka kwamalungu.

Ukuthambeka okudilikayo: Izinga lokuncitshiswa kwe-ABS limalunga ne-0.4% ukuya kwi-0.7%. Kubalulekile ukuqinisekisa ukuthambeka okwaneleyo kokudilikayo (ngesiqhelo ngaphezulu kwe-1° ukuya kwi-1.5°) ukuze kube lula ukuphuma nokuthintela imikrwelo yomphezulu.

Ingongoma yesine ephambili: Uyilo lweMveliso – “Iingenelo ezisisiseko
Uyilo oluhle kakhulu luyimfuneko ukuze imveliso iphumelele.

Ubukhulu bodonga obufanayo: Lo ngumgaqo woyilo obaluleke kakhulu. Ubukhulu bodonga obungalinganiyo yeyona nto ibangela ukushwabana, ukugoba kunye noxinzelelo lwangaphakathi. Kucetyiswa ukuba ubukhulu bodonga bube yi-2.0-3.5mm.

Utshintsho lwekona ejikelezileyo: Zonke iindawo ezidibana kuzo iikona zangaphakathi nezangaphandle kufuneka zitshintshwe zibe ziinguqu zekona ejikelezileyo. Oku kunokunciphisa kakhulu uxinzelelo, kuphucule ukuhamba kweplastiki, kwaye komeleze amandla eendawo.

Uyilo lweembambo zokuqinisa: Ubukhulu beembambo akufuneki budlule i-50%-60% yobukhulu bodonga kwindawo yokuncamathisela ukuthintela amabala okushwabana ngasemva.

Ingongoma yesihlanu: Ukulungiswa emva kokulungiswa
Unyango lokutsalwa kwe-Annealing: Kwiindawo ezinexinzelelo olukhulu lwangaphakathi okanye iimfuno zokuchaneka okuphezulu kakhulu, unyango lokutsalwa kwe-annealing lunokwenziwa. Beka iindawo kwi-oven yokujikeleza komoya oshushu kwaye uzifudumeze kwi-70-80℃ (ngaphantsi kobushushu bokuguquguquka kobushushu be-ABS) iiyure ezi-2-4, uze uzipholise kancinci ukuya kubushushu begumbi. Le ndlela inokuphelisa ngempumelelo uxinzelelo lwangaphakathi, iphucule uzinzo lobukhulu kunye nokumelana neekhemikhali.
