Nivå 6: 10.000 kg=(0.325+No. 5 4.675 miisaanka + No. 6 5.000 miisaanka)=98.07 N
Nivå 7: 12.000 kg=(0.325+No. 5 4.675+miisaanka+No. 6 5.000+Lambarka 7
Nivå 8: 21.600 kg=(0.325+No. 2 0.875+miisaanka+No. 3 1.835+No. 4
3.475+No.5 4.675+No.6 5.000+No.7 2.500+No.8 2.915 miisaanka)=211.82 N
Khaladka qaraabo ee culeyska culeysku waa ≤0.5%.
3. Kala duwanaanta heerkulka:50-300 ℃

6. Xaaladaha deegaanka shaqada:heerkulka jawigu waa 10 ℃-40 ℃; qoyaanka qaraabada ah ee deegaanka waa 30% -80%; ma jiro meel dhexe oo daxalaysa oo ku wareegsan, ma jiro hawo xoog leh oo isku xidha; Gariir ma jiro, ma jiro faragelin xoog leh oo birlab ah.
7. Cabirrada dibadda ee qalabka: 250×350×600=(dhererka×ballaadh×dherer)
Qaab dhismeedka iyo mabda'a shaqada:
DRK208 tijaabiyaha heerka qulqulka dhalaalka waa mitir caag ah oo dibadda loo saaray. Waxay isticmaashaa foornada kuleylka kuleylka sare leh si ay uga dhigto shayga la cabbiray inuu gaaro xaalad dhalaalaysa oo hoos timaada xaaladda heerkulka la cayimay. Shayga tijaabada ah ee xaaladan dhalaalaysa waxa lagu mariyaa tijaabada extrusion iyada oo loo marayo dalool yar oo dhexroor gaar ah oo hoos yimaada cufis-jiidad miisaan loo qoray. Wax soo saarka caaga ah ee shirkadaha warshadaha iyo cilmi baarista cutubyada cilmi-baarista sayniska, "dhalaalida (mass) heerka socodka" waxaa badanaa loo isticmaalaa in lagu muujiyo sifooyinka jireed ee walxaha polymer ee gobolka dhalaalka ah sida dareeraha iyo viscosity. Waxa loogu yeero tusmada dhalaalka waxaa loola jeedaa celceliska miisaanka qayb kasta oo ka mid ah extrudate oo loo beddelay mugga extrusion ee 10 daqiiqo.
Mitirka qulqulka dhalaalka (cufka) waxaa muujiyay MFR, halbeeggu waa: garaam/10 daqiiqo (g/min), qaacidada waxaa lagu muujiyay: MFR (θ, mnom)
=tref .m/t
Qaabka: θ—— heerkulka tijaabi
mnom- culayska magaca Kg
m —— celceliska cufka goynta g
tref ——waqtiga tixraaca (10min), S (600s)
t —— gooyay muddada u dhaxaysa s
Qalabkani wuxuu ka kooban yahay foornada kululaynta iyo nidaamka xakamaynta heerkulka waxaana lagu rakibay saldhigga jidhka (column).
Qaybta xakamaynta heerkulku waxay qabataa awoodda kombuyuutarrada hal-chip ah iyo habka xakamaynta heerkulka, kaas oo leh awood xoog leh oo ka-hortagga, saxnaanta heerkulka sare, iyo xakamaynta xasilloon. Xadhkaha kuleylka ee foornada ayaa ku dhaawacma usha kuleylka si waafaqsan xeer gaar ah si loo yareeyo heerkulka heerkulka si loo buuxiyo shuruudaha caadiga ah.
Ka taxadaritaan:
1. Barkinta korontadu waa in ay leedahay dalool dhulka hoostiisa ah oo si la isku halleyn karo u fadhiyo.
2. Haddii muuqaal aan caadi ahayn uu ka soo muuqdo LCD, dami marka hore, ka dibna dib u deji heerkulka tijaabada ka dib markaad shid, oo bilaw shaqada.
3. Inta lagu jiro hawlgalka caadiga ah, haddii heerkulka foornada uu ka sarreeyo 300 ° C, software-ku wuu ilaalin doonaa, wuxuu joojin doonaa kuleylka, wuxuuna soo diri doonaa alaarmiga.
4. Haddii ay dhacdo dhacdo aan caadi ahayn, sida heerkulka aan la xakameyn karin ama la soo bandhigi karin, iwm, waa in la xiro oo la hagaajiyaa.
5. Markaad nadiifinayso usha piston, ha ku xoqin walxo adag.
Xusuusin: Horumarka tignoolajiyada awgeed, macluumaadka waa la beddeli doonaa ogeysiis la'aan. Alaabtu waxay ku xiran tahay badeecada dhabta ah xilliga dambe.
