Sidee loo doortaa habka saxda ah ee granulation-ka marka agabyo kala duwan la beddelo?

Marka resins-ka saafiga ah "la beddelo", badanaa waxaa jira isbeddel ku yimaada habka ugu habboon ee loo isticmaalo granulation-ka.

Tusaale ahaan:

• Buuxinta, gaar ahaan buuxinta sare, badanaa waxay ka dhigtaa LLDPE ama LDPE granulation balaastig ah in laga beddelo granulation giraanta biyaha una beddelo dusha sare ee hawada lagu qaboojiyo oo kulul. Labaduba waxay kordhiyaan adkaanta, iyo keydinta tamarta (ka dib qalajinta); qaabka hadhuudhku waa mid qurux badan wuxuuna yareeyaa luminta dabiiciga ah ee budada geesaha.

• La xoojiyay, sababtoo ah jiritaanka fiber galaas ama fiber kaarboon, sidaa darteed qaar ka mid ah resin-ka hawada ku qaboojiya (polyethylene cufnaanta sare, ABS, iwm.) oo adeeca ayaa dib ugu soo noqda jarista qabow ee caadiga ah ee xarigga (biyaha). "Guud" iyo "injineernimada" (balaastikada) kama reebna.

• Adkaysan, sida walxaha bamperka TPV ee badanaa la isticmaalo (PP+EPDM+POE dynamic vulcanization), sababtoo ah kala firdhinta budada caagga ah ee marxaladda joogtada ah ee PP, taasoo ka dhigaysa kulaylka giraanta biyuhu inay noqoto mid la doorbido. Waa muuqaal wanaagsan oo qiimo fiican leh.

○ Dib-u-soo-saarid fal-celin ah

(1) Qalabka fiilada isku xidha kiimikada (XL-PE) waa doorashada la door bidayo ee dusha sare ee hawada lagu qaboojiyo. Warshad badan oo ka mid ah qalabka fiilada,fur mataano ah/ Mashiinka hal boolal ah oo laba-tallaabo ah + qaboojinta hawada oo kulul (ama kulul oo aan caadi ahayn) waa qaab-dhismeedka caadiga ah ee wax soo saarka ee la jaan qaadaya SPVC iyo XLPE.

(2) Soo saarista iyo soo saarista polypropylene xoog dhalaal badan (HMS-PP), falcelinta PP ee laamoodsan ayaa si fiican u aqbali karta walxaha kulul ee giraanta biyaha.

Alaabada caadiga ah ee wax laga beddelay ama xulashada muunadda jarista dufcadda sare ee caadiga ah

• Qalabka dahaarka fiilada SPVC ama agabka caafimaad ee caadiga ah ee hufan, waxaa la doorbidaa in dhammaan dusha sare ee hawada lagu qaboojiyo ay kulul yihiin. Sidoo kale RPVC waa sidaas oo kale, laakiin tiro yar.

• Polystyrene, iyadoon loo eegin HIPS ama GPPS, dooro suunka tuurista (qaboojinta biyaha ee u janjeerta) ee ugu badan.

• Alaabada caadiga ah ee loo isticmaalo ABS, badankood waxay doortaan inay jiidaan (biyo) jarista qabow (qaabka qamadiga khafiifka ah iyo kan dheer ayaa ah kan ugu caansan). Dadku waxay isku dayeen firfircoonida hawo-qaboojinta ama firfircoonida giraanta biyaha oo dhan dhib la'aan, qaabka qamadiga sidoo kale waa mid qurux badan (gooni-gooni ah oo togan). Marka awoodda wax soo saarku ay ka weyn tahay 3-4t/saacaddii, waa macquul in loo beddelo mashiinka shubka kulul ee biyaha hoostooda ama suunka shubka.

• Qalabka fiilada ee gaashaanka ah ama kuwa nus-gaaban, xulasho yar oo giraanta biyaha ah, xulasho ballaaran oo biyaha hoostooda ah (oo si xamaasad leh u socda).

• Qalabka fiilada isku xidha ee Silane, xariiq yar dooro giraanta biyaha, oo weyn (sida xariiqda 96/250) dooro biyaha hoostooda (kulul).

• Soo saarista iyo soo saarista HFFR (qalabka fiilada aan qiiqa lahayn ee halogen-ka lahayn), oo la jaan qaadaya qalabka XLPE, laakiin qaabaynta boolal-ka extruder-ka ayaa isbeddelaysa.

• Dhamaadka Copolymer formaldehyde (POM), wuxuu dooran karaa giraanta biyaha ama biyaha hoostooda (la jaray).

• TPU (thermoplastic polyurethane elastomer), kuleyl badan oo biyaha hoostooda ah, laakiin jihada isku midka ah ee qaybta cabbiraadda dibadda waa in loo hagaajiyaa cadaadiska dhismaha.

Dufcaddii ugu horreysay ee fiilada PET, waxaa lagu jari karaa qabow iyadoo la jiidayo (biyo) ama lagu shubi karo jaritaan qabow.

• PPC-ga caanka ah ee hoos u dhigista qiiqa (polypropyl carbonate), waxaa lagu qasi karaa ku dhawaad ​​​​nooc kasta oo resin burbur ah (TPS, PLA, PBAT, PBS, PHBV, PHA, PVA, PCL, PGA) iyo granulation.

• Fiilada galaaska dheer ee la dahaadhay (LFI-PP, LFI-PA).
• Warshadda filimka neefta leh ee PE-ga ah ee si caadi ah loo isticmaalo - isku darka iyo budada;

• Balaastikada isku dhafan ee ester-ka ee Cellulose acetate – isku darka granulation;

• TPEE (baloog copolymer ester caag ah) – isku darka granulation;

• K resin - granulation of wax soo saarka iyo walxaha wax laga beddelay;

• SBS, SIS, SEBS block elastomer granulation ama devolatilisation granulation;

• POE GRAPHT, EPDM GRAPHT iyo walxo kale oo isku dhafan oo isku dhafan - granulation;

• Qalabka qodista polyethylene-ka miisaanka molecular-ka aadka u sarreeya (UHMW-PE), sida isku-darka granulation-ka;

• Wax Polyethylene ah (PEW) — isku-darka, granulation-ka iyo micro-granulation;

• Resin batrool (C5 ama C9) — maaddooyinka iyo granulation gaar ah;

• Naylon (PA6+PA12+SiC) oo lagu daro isku darka fiilooyinka xoqan iyo jarista.
