Polyamide Hot dhalaalaysa Garnules

Polyamide Hot{0}}Granules-ka dhalaalayaa waa dhalaal -midab leh, sare -waxqabad heerkulbeeg ah oo loogu talagalay jawi isku imaatin oo dalbanaya halka xawaaraha, xoogga iyo kala duwanaanshiyaha ay si isku mid ah muhiim u yihiin. Xabagta waxa loo keenay sidii lebbis, hoose- budh cylindrical granules oo si degdeg ah u dhalaalay 140-160 darajo ilaa hooseeyo{11} dareeraha viscosity (≈ 3 000–5 000 mPa·s @ 160 digrii). Viscosity-ka dhalaalka ah ee sida gaarka ah u hooseeya waxa uu xaqiijiyaa qoynta heersare ah ee dabada, qallafsan ama la midka ah -warqad, aan{13}}warbaahinta tolsan, maqaar, ABS, PC, PA, birta iyo aluminium-iyada oo aan loo baahnayn qalab-saldhig ama qalab farsamo.

Xabaggu si ulakac ah ayaa loogu dheellitirayaa si dhaqsaha leh loo dejiyo{0}}: waxay ku gaartaa awoodda wax-ka-qabashada 5-10 ilbiriqsi ka dib marka la isku xidho, taasoo u oggolaanaysa hawl-gallada hoose sida gooynta, rarista ama baakaynta inay isla markiiba bilaabaan. Haddana waxa ay bixisaa wakhti dhexdhexaad ah oo ah 4–12 ilbiriqsi (substrate and ambient based), siinta hawl wadeenada ama qalabeeyayaasha robotiga daaqad ku filan si ay isugu toosiyaan qaybaha, meelaynta saxda ah ama u fuliyaan talaabooyinka kulanka sare ka hor inta aanay xidhin xidhidhku si aan leexleexad lahayn. Isku dhafkan waxa uu soo gaabinayaa wakhtiyada wareeggu sareeyo{7}}xawaaraha wareegtada ama xariiqyada tusmaynta iyadoo la yareynayo diidmada uu keeno maqaarka dhicisoobay-

Marka la qaboojiyo, laf dhabarta polyamide waxay keenaysaa filim adag oo dabacsan oo leh:

- Xoog xajin ka weyn ama la mid ah 6 MPa

- Xeebta A engegnaanta 92–96

Xidhiidhku waxa uu ahaanayaa mid adkeysi leh laga bilaabo -20 darajo ilaa +110 darajo , oo leh xajmiyo kooban ilaa 130 darajo iyada oo aan gurguurin ama jabin. Waxay muujisaa iska caabin heer sare ah:

{{0} Saliid

- caagadaha

{{0} Ku milo acids/alkalis

- Soo-gaadhista UV

Tani waxay ka dhigaysaa granules ku habboon:

1. Wershadaha shaandhaynta - xasilinta jilicsan, dhammaatay{1}} xidhitaanka koofiyadda iyo isku xidhka HEPA, shidaalka baabuurta iyo filtarrada hawada; xabagta waxay u adkaysataa kala duwanaanshaha cadaadiska garaaca wadnaha iyo kulul - tijaabooyinka gabowga saliidda > 1 000 h @ 95 darajo .

2. Samaynta kabaha -PA kulul{1} granules dhalaalay ayaa lagu dhalaaliya 160-180 buufin ama boos - khadadka jaakad si ay u dhigaan khafiif, sare{5}lakabka xoojinta kaas oo ilaalinaya fufyada suulasha, miisaska iyo sabuuradaha insole ee ka hooseeya 5 s.
Tolmada polyamide ee adag, dabacsani waxay badbaaday 100 000 dabacsanaan iyo wareegyada dhaqida 40 digrii, wali waa mid neefsanaysa oo dareere ah-free.
Sababtoo ah waxay dib u dhalaalisaa kaliya 120 -130 darajo , isla koolada waxay u adkeysaneysaa foornooyinka qaabeynta ka dib iyo vulcanization, taasoo ka dhigaysa doorashada la isku halayn karo ee badbaadada, bannaanka iyo kabaha ciyaaraha fudud.

3. Qalabaynta cadaadiska hoose ee qaybaha korantada/elektarooniga - Kobcinta shirarka PCB, kala-goysyada fiilooyinka, dareemayaasha iyo dabaylaha gariiradda; cadaadiska irbad yar (<10 bar) eliminates mechanical stress, while the amber color allows visual inspection and laser marking.

Alaabta ayaa u hogaansan RoHS iyo REACH, kuma jiraan wax dareere ah ama isocyyanates, waana 100 % adag- baabi'inta qiiqa VOC iyo fududaynta badbaadada goobta shaqada. Granules waxaa lagu farsamayn karaa:

- Piston ama gear-ka caadiga ah{1}}nooca dhalaaliyeyaasha

- Nidaamyada hopper ee otomaatiga ah

- Unugyada haanta dib u wareega

Muuqaalada viscosity-ka iyo degenaanshiyaha kulaylka ee aad u wanaagsan (In ka yar ama la mid ah 2 % mawjadaha mawjadaha ka dib 48 h @ 180 digrii) waxay yareeyaan samaynta char iyo wakhtiga hoos u dhaca qalabka. Marka la soo koobo, kuwan amber polyamide hot-granules dhalaalay waxay siiyan injineerada wax soo saarka hal, madal xabag adag oo midaysa daawaynta degdega ah, cafiska wakhtiga furan iyo waxqabadka raaga ee filtarrada, kabaha iyo elektiroonigga saxda ah.
