Aragtida guud ee masterbatch caag ah
Masterbatch caag ahwaxaa loo arki karaa sida polymersmasterbatch.Polymers waxaa laga samayn karaa noocyo badan oo kala duwan oo 'mers' ah oo u taagan unugyada kiimikada.Unugyada kiimikaad intooda badan waxaa laga helaa saliid ama hydrocarbons kale.Hydrocarbons waa sida ay u muuqdaan, oo ka samaysan hydrogen iyo carbon.Haddaba, balaastiiggu waxay ka samaysan yihiin (inta badan) hydrogen iyo carbon kuwaas oo la isku keenay si ay u sameeyaan meeris (sida ethylene ama propylene) ka dibna meers-kani waxay isku xiraan si ay u sameeyaan silsilado iyo marka silsiladahani ay ku filan yihiin inay noqdaan 'poly' badanaa marka ugu yaraan 100 ka mid ah mers ayaa isku xiran, waxaan helnaa walxo balaastik ah / polymeric ah.
Masterbatch caag ahWaxay ka tirsan yihiin qoyska thermoplastic waxay ka kooban yihiin unugyo silsilad dheer oo ka kooban kaarboon iyo hydrogen oo loo yaqaan polymers.Eraygu wuxuu isku daraa "poly" oo tilmaamaya qaar badan iyo "mer" oo tixraacaya cutubyada soo noqnoqda molecular ee gaarka ah ee la isku xidhay.Qaybaha mer ee noocyada kala duwan ee balaastikada, xoogga curaarta molecular ee isku haya meers-ka midba midka kale iyo dhererka silsiladaha polymer ayaa ah kuwa aasaasiga ah ee go'aamiya sifooyinka caaga ah.Qaar ka mid ah balaastikada ayaa beddela in ka badan hal nooc oo unugyo mer ah.
Caagadahamasterbatchqoyska heerkulbeegga halka ay la mid yihiin kuwa kor lagu soo sheegay waxay leeyihiin xiriiro kala duwan oo u dhexeeya mers oo ay ku jiraan isku-xireyaasha kuwaas oo siinaya siyaalo kala duwan oo ay ku jiraan xaaladaha heerkulku sarreeyo iyo awood la'aanta inuu dhalaali karo ka hor inta uusan burburin marka heerkulku kordho.
Burburinta masterbatch caag ah
Wax badan oo ka mid ahmasterbatch caag ahbuskud baa dilaacday!
buskudka uumi ee ugu weyn.Laakiin maahan mid gaar ah.
Waxa jira tiro dhan oo heerkulbeegyo ah kuwaas oo laga soo minguuriyay walxo cayriin ah oo loo yaqaan ethylene.Ethylene waxaa loo soo saaraa siyaalo kala duwan, inta badan waxaa laga soo saaraa saliid ama gaaska quudinta.
Mid ka mid ah dariiqooyinka caanka ah waa in la geliyo quudinta qashinka uumiga iyo natiijooyinka ethylene, iyo waxyaabo kale oo aad u badan.Ethylene ayaa markaa polymerized laga dhigayaa polyetylen ama polypropylene inta badan laakiin maaha mid gaar ah.PVC, PS, PET, butadiene ayaa sidoo kale la sameeyay.
Waa kan qayb ka mid ah maqaal taas sharaxaysamasterbatch caag ahaad uga wanaagsan:
"Ethylene waa meesha laga bilaabo afar badeeco dhammaadka aadka u bislaaday: polyetylen (saddex nooc: LDPE, LLDPE, iyo HDPE), ethylene oxide, ethylene dichloride (hore u ah vinyl chloride monomer), iyo ethylbenzene (hore u ah styrene).Mugga yar, alaabada khaaska ah waxaa ka mid ah α-olefins toosan, vinyl acetate monomer, iyo ethanol synthetic, iwm."
Kuwa soo socda waa liiska qaar ka mid ah ethylene caanka ahmasterbatchalaabta:
| PVA Poly (vinyl acetate), poly (alkolada vinyl) | PET Poly (etylene terephthalate) |
| PVC Poly (vinyl chloride) | PS polystyrene |
| LLDPE Polyetylen cufnaanta hoose ee toosan | PEG Poly(etylene glycol) |
| LDPE polyetylen cufnaanta hoose | HDPE cufnaanta sare ee polyetylen |
Ilaa hadda dariiqa wax soo saarka ee ugu badan ee ethylene waa uumiga dilaaca xooluhu gaaska ah (ethane, propane, ama butane) ama kaydka dareeraha ah (naphtha ama saliid gaaska).Heerkul aad u sarreeya oo ka bilaabmaya 850 darajo Celsius ama in ka badan, taxanahan nidaamsan ee dildilaaca makaanikada aan kicinta ayaa la sameeyay.Ethylene waa badeecada loogu talagalay;laakiin molecules kale oo qiimo leh, sida propylene, butadiene, iyo benzene, ayaa la soo saaray.
Wax-soo-saarka mid kasta oo ka mid ah badeecooyinku inta badan waa shaqada xoolaha la isticmaalo.Dildilaaca ethane wuxuu bixiyaa ku dhawaad wax-soo-saarkooda;Laakin dildilaaca naphtha wuxuu bixiyaa xaddi badan oo propylene, butadiene, iyo benzene.Sida adduunka oo dhan loo arko, dilaaca uumi waxa loo arki karaa mid ka mid ah ilaha ugu muhiimsan ee butadiene, propylene iyo khayraadka hoose ee hogaaminaya benzene.Sawirka soo socdaa wuxuu muujinayaa naqshadaynta taxanaha nidaamsan ee dildilaaca makaanized ee habka ugu fudud.
