Ngamakhulu eemveliso kunye neeresin zobunjineli ezikhoyo kwimarike namhlanje, inkqubo yokukhetha imathiriyeli yemisebenzi yokubumba inaliti yeplastiki inokubonakala isoyikisa ekuqaleni.
Kwi-DJmolding, siyayiqonda izibonelelo ezikhethekileyo kunye neepropathi zeentlobo ezahlukeneyo zeplastiki kwaye sisebenza ngokusondeleyo nabathengi ukuze bafumane eyona nto ifanelekileyo kwiprojekthi yabo.
Yintoni iiResins zePlastiki?
Siphila kwihlabathi elingqongwe ziintlaka zeplastiki. Ngenxa yeepropathi zabo ezininzi ezinqwenelekayo, iirasi zeplastiki zinokufumaneka kuyo yonke into ukusuka kwiibhotile kunye nezikhongozeli ukuya kwiimoto kunye nezinto zonyango kunye nokunye okuninzi. Iiplastiki zeplastiki ziquka usapho olukhulu lwezinto eziphathekayo elowo uneempawu zabo ezizodwa ezenza ukuba zilungele izicelo ezahlukeneyo. Xa ukhetha i-resin efanelekileyo yeprojekthi yakho, kubalulekile ukuqonda ukuba yintoni uhlobo ngalunye olunokuthi lunikeze.
Yintoni uMahluko phakathi kweResin kunye nePlastiki?
Iresin kunye neplastiki zombini zikhompawundi ezibalulekileyo, kodwa zibonisa umahluko ophambili, kubandakanya:
*Imvelaphi: Ngelixa i-resin zisenzeka ngokwemvelo kwizityalo, iiplastiki zenziwe kwaye zivela kwi-petrochemicals.
*Ingcaciso: Iplastiki luhlobo lweresin eyenziweyo, ngelixa i-resin zikhompawundi ze-amorphous ezinokuthi zibe semi-solid okanye ziqine.
*Uzinzo kunye nokungcola: Iiplastiki zizinzile ngakumbi kune-resin kwaye ayinakho ukungcola. Ngee-resin, ukungcola akunakuphetshwa.
*Ubunzima: Iplastiki ixinene kwaye iqinile, ngelixa i-resin iqhelekile ukuba yigluy kunye ne-viscous substance.
*Impembelelo kokusingqongileyo: Kuba i-resin iyindalo, inika enye indlela ehambelana nokusingqongileyo kwiplastiki. Iplastiki yonakala kancinane kwaye kaninzi inezongezo eziyityhefu ezinokukhokelela kungcoliseko lwendalo esingqongileyo.
Izicelo eziqhelekileyo zokuBunjwa kwePlastiki yeNtofu yeResin
I-injection yeplastiki yokubumba iyahambelana noluhlu olubanzi lwezinto ze-resin. Xa umisela i-resin efanelekileyo kwiimfuno zakho, kubalulekile ukuqonda iimfuno zesicelo sakho. Ukusetyenziswa okuqhelekileyo kweerensi zokubumba iinaliti ezahlukeneyo ziquka:
ABS
I-ABS eyenziwe nge-injection isetyenziswe kwiindidi ezahlukeneyo zezicelo, kubandakanywa iiplati zeplastiki zodonga zombane, i-headgear ekhuselayo, izitshixo zebhodibhodi, izixhobo ze-elektroniki, kunye nezixhobo zemoto ezifana namalungu omzimba we-auto, ivili, kunye needeshibhodi. Ikwasetyenziselwa uluhlu lwezinto zokufakelwa kwimizi-mveliso, izixhobo zemidlalo, kunye neempahla zabathengi.
Celson (Acetal)
Ngenxa ye-coefficient ephantsi yokukhuhlana, i-Celson eyenziwe ngenaliti ilungele amavili e-pulley, amabhanti okuhambisa, iigiya kunye neebheringi. Esi sixhobo sinokufumaneka kwizinto ezahlukeneyo zobunjineli bokusebenza okuphezulu, iinkqubo zokutshixa, imipu, iifreyimu zeglasi yamehlo, kunye neziqhoboshi.
Iipolypropylene
I-polypropylene yokubumba i-injection isetyenziswa kwiintlobo ngeentlobo zemizi-mveliso, yorhwebo, kunye nezicelo zabathengi. Umzekelo, inokufumaneka kwizixhobo zezixhobo zamandla, izixhobo zombane, izinto zokupakisha, izinto zemidlalo, izitya zokugcina, kunye nezinto zokudlala zabantwana.
HIPS
Ngenxa yokuba i-HIPS ibonakalisa amandla empembelelo ephezulu, inokufumaneka kwizixhobo zombane, izixhobo zoshicilelo, imiqondiso, kunye nezixhobo zezixhobo. Ezinye izicelo eziqhelekileyo ziquka iithoyi zabantwana kunye nezixhobo zombane.
LDPE
Ngenxa yokuguquguquka kwayo kunye nokuchasana nokufuma kunye neekhemikhali, i-LDPE eyenziwe ngesitofu isoloko isetyenziselwa izicelo ezibandakanya amacandelo esixhobo sonyango, iingcingo kunye ne-cable insulators, iibhokisi zezixhobo, kunye nezinto zokudlala zabantwana.
Imiba ephambili ekufuneka iqwalaselwe xa ukhetha iMathiriyeli yokuBumba isitofu
Amalungu eplastiki aqhelekileyo avela kwi-DJmolding ukuqinisekisa ukuba ukhetha i-resin efanelekileyo yeprojekthi yakho, gcina engqondweni oku kuguquguquka kulandelayo:
*Amandla empembelelo - Ezinye izicelo zifuna amandla asisiseko ngakumbi kunezinye, ngoko ke amandla empembelelo ye-resin ye-Izod kufuneka amiselwe kwasekuqaleni.
*Tensile strength - Amandla okugqibela okuqina, okanye amandla okugqibela, alinganisa ukuxhathisa kwe-resin kuxinzelelo kunye nokukwazi kwayo ukumelana nomthwalo onikiweyo ngaphandle kokusahlula.
*Imodyuli yeFlexural yokwaluka — Oku kubhekiselele kwinqanaba apho into inokugotywa ngaphandle komonakalo kwaye iphinde ibuyele kwimo yayo yokuqala.
*Ukuphambuka kobushushu — Oku kubaluleke kakhulu kwizicelo ezifuna ukusebenza kwe-insulating okanye ukunyamezela kwiindidi ezahlukeneyo zokushisa.
*Ukufunxwa kwamanzi — Oku kusekelwe kwipesenti yolwelo oluthatyathwe yinto emva kweeyure ezingama-24 zokuntywiliselwa.
UKhetho lweMathiriyeli yesiko kunye no-DJmolding
I-Djmolding ngumvelisi wokubumba inaliti yeplastiki, yenza iindawo zeplastiki nge-acrylic (PMMA), i-acrylonitrile butadiene styrene (ABS), inayiloni (polyamide, PA), ipolycarbonate (PC), ipolyethylene (PE), ipolyoxymethylene (POM), i-polypropylene (PP), i-polystyrene (PS) kunye nokunye
Ukukhetha izinto ezifanelekileyo kwasekuqaleni akuyi kugcina ixesha kuphela, kunye nemali, kodwa kuya kuqinisekisa ukusebenza kakuhle kunye nokwenziwa. Phanda ukhetho lwakho ngononophelo, kwaye udibane nesibumba esinamava seplastiki yokutofa ukuze uncede ubone ukhetho olufanelekileyo.
