Codsiga fibre polypropylene ee miiqan, ku habboonaantawax polyetylen ahwaa xaddidan tahay.Fiilooyinka yaryar ee caadiga ah iyo fiilooyinka tayada sare leh, gaar ahaan dhogorta jilicsan sida denier ganaaxa iyo fiilooyinka BCF ee ku habboon jeexjeexyada iyo jaakadaha dharka, polypropylene ayaa inta badan ka door bida shamac polyetylen.
Sainuo-nadiif sarepolypropylene waxviscosity dhexdhexaad ah, dhibic dhalaalaysa sare, saliid wanaagsan, iyo kala firdhiso wanaagsan.Hadda waa kaaliye aad u fiican oo loogu talagalay farsamaynta polyolefin, iska caabin heerkul sare ah, iyo ku-shaqeyn sare.

Marka hore, sababtoo ah iswaafajinta u dhaxaysa polypropylene iyo polyetylen, aad bay u adag tahay in la sameeyo isku-dhafka isku midka ah ee dareenka micro, taas oo u horseedi doonta kala-soocidda wajiga.
Marka labaad, sababtoo ah barta dhalaalaysa ee wax xumbada polyetylen aad ayuu uga hooseeyaa midka polypropylene ama polypropylene, way adagtahay in lala tacaalo sifooyinka kala duwan ee dhalaalka labada polymers.Sinnaan la'aanta iyo rheology-ga aan ku habboonayn ee alaabta ayaa laga yaabaa inay u horseeddo dhammaadka jebinta habka wareegga.Dhibaatooyinkan soo raaca awgood, sifooyinka dharka jirka ee fiberku way ka sii daraan.
Waqtigan xaadirka ah, waxaa lagama maarmaan ah in la isticmaalo wax polypropylene leh maqaar hooseeya.Maqnaanshaha hoose iyo qoynta wanaagsan awgeed, waxay ku qoysin kartaa midabka waqti gaaban.Intaa waxaa dheer, marka sawiridda iyo kuleylinta dejinta polypropylene fiber, waxaa laga heli karaa heerkulka daaweynta kulaylka (badanaa ku saabsan 130c), kaas oo ku dhex jira kala duwanaanshaha heerkulka dhalaalay ee wax polyetylen.
Sababtoo ah isbeddelka qaabdhismeedka crystalline ee fiber-ka aasaasiga ah ee polypropylene, waxaa la ogaan karaa in dhuxul polyetylen ah oo dhalaalaysa ay ka soo baxdo dusha sare ee fiber-ka ee matrix polypropylene, oo kaliya maaha wax saafi ah, laakiin sidoo kale midabka ayaa la keeni doonaa dusha sare.

Ugu dambeyntii, iswaafajinta ka dhexeeya wax polypropylene iyo resin polypropylene waxay ku fiican tahay dhinacyada yaryar iyo makro, waxayna saameyn yar ku leedahay sifooyinka farsamada.Waxaa jira laba nooc oo wax polypropylene ah oo lagu polymerized by metallocene catalytic technology: mid waa homopoly polypropylene wax, iyo alaabta ceeriin waa propylene;Midda kale waa wax-ka-soo-baxa polypropylene, kaas oo u isticmaala propylene iyo ethylene sida alaabta ceeriin.
Guud ahaan, wax-ka-soo-saarka homopolypropylene waxa uu leeyahay bar dhalaaleed sare oo u dhaxaysa 140-160c, miisaan unugyo ah oo kumanaan ilaa tobanaan kun ah, oo u dhiganta viscosity Brookfield laga bilaabo daraasiin ilaa dhowr qalalan, crystallinity sare iyo engegnaan sare.Meesha dhalaalaysa ee wax polypropylene copolymerized caadi ahaan waa inta u dhaxaysa 80-110 ℃, mawqifka Brookfield waa boqollaal ilaa kun ama xitaa tobanaan kun, miisaanka unugyaduna waa kumanaan ilaa tobanaan kun.Iyadoo ay ugu wacan tahay ku-darka ethylene comonomer ee polypropylene koobiyeerka, taas oo carqaladaynaysa habaynta joogtada ah ee molecules propylene, crystallinity ee polypropylene koobiyeerka ayaa hooseeya, barta dhalaalaysa ee gaarka ah ayaa sidoo kale hooseysa.
Marxaladda qoynta midabka midabka, qoynta shamac hooseeya ayaa si dhakhso ah u dhacda, waxtarka qoyntana waa sarreeyaa.Laakiin waxaa loo baahan yahay in extrusion silig.Marxaladda granulation, waxaan rajaynaynaa in dhuka uu leeyahay viscosity gaar ah, kaas oo si fiican u wareejin kara xoogga dhogorta u dhexeeya midabka iyo resin dhalaalay, si midabka qoyan waxaa si siman loo qaybin karaa in dhalaalka resin.Waqtigaan, waxaa loo tixgelin karaa in la isticmaalo wax polypropylene leh dhibic dhalaalaysa hoose iyo wax polypropylene leh viscosity sare, si loo gaaro kala firidhsan ugu fiican.
