Asalkii hore ee farsamada

xabagta polypropylene sababtoo ah waxa uu leeyahay qallafsanaan wanaagsan iyo iska caabin kulaylka, iyo ka dib markii wax ka beddelka ka dhigan tahay hodan, sababtoo ah tan waxaa si tartiib tartiib ah bedelay qaar ka mid ah balaastikada injineernimada, oo si ballaaran loo isticmaalo baabuurta, qalabka korontada iyo guryaha iyo beeraha kale.

Gaar ahaan copolymerization polypropylene resin, by in horumarka geedi socodka wax soo saarka iyo tignoolajiyada kicinta, siinaysaa alaabta wax ka badan oo waxtar leh oo dhamaystiran, Laakiin saamaynta ayaa la isu ururiyey ee wax soo saarka propylene uu leeyahay dhibaatooyin farsamo oo weyn, gaar ahaan dhinacyada sida adkaanta alaabta iyo qallafsanaan. dareere ah, sidoo kale ma si buuxda u buuxsamo kartaa in ku filan meelaha qaar ka mid ah baahida, sidaas darteed sidoo kale u baahan tahay oo ku salaysan saamaynta brand ee jira copolymer polypropylene ka dib markii wax laga beddelo, taas oo ah iyada oo lagu daro wakiilka nucleating elastomer filler inorganic si loo gaaro wax sida qallafsanaan sare.

Qallafsanaanta alaabta polypropylene ee leh adkeysi sare iyo dheecaan sare ayaa badanaa lagu wanaajiyaa iyadoo lagu darayo wakiilka nuclei-ka ama buuxinta aan noolaha ahayn.Marka lagu daro fillerka aan organic ahayn sida calcium carbonate, budada talcum, mica, diatomite, iwm., foorarsiga resin polypropylene Awoodda dabacsanaanta iyo jilicsanaanta jilicsan ayaa si tartiib tartiib ah u kordheysa, laakiin isla mar ahaantaana, dhererka iyo saameynta saameynta polypropylene ayaa noqon doonta. la dhimo, iyo midabka iyo hoos u dhaca alaabta polypropylene ayaa saameyn doonta.Intaa waxaa dheer, ku darida tiro badan oo ah buuxinta aan dabiiciga ahayn waxay hagaajin doontaa cufnaanta alaabta, xaddidaysa miisaanka fudud ee alaabta, gaar ahaan goobta codsiyada baabuurta.

Sanadihii la soo dhaafay, codsiga wakiilka nukliyeerka ee polypropylene ayaa si tartiib tartiib ah u kordhay.Dhir badan oo batroolka kimikalka ah waxay ku daraan wakiilka nuclei-ka habka granulation ee soo saarista xabagta polypropylene.Ku darida wakiilka nukliyeerka ma aha oo kaliya in aysan saameyn xun ku yeelan midabka polypropylene, laakiin sidoo kale waxay hagaajin kartaa caabbinta kulaylka iyo dhalaalka resin polypropylene.5%, inkasta oo qadarka wax lagu kordhinayo uu yar yahay, laakiin qiimaha wakiilka nukliyeerka ayaa qaali ah (sida ku cad tayada badeecada iyo heerka farsamada, qiimaha badanaa waa tobanaan kun ilaa shan boqol oo kun), waxay kordhin doontaa kharashka xabagta polypropylene tan oo ah dhowr boqol oo yuan.

Halabuurka polypropylene waxaa laga sameeyaa alaabta ceeriin ee soo socota miisaan ahaan:

xabagta polypropylene100;

Dejinta kuleylka 0.05 ~ 2;

cusbo bir ah oo nadiif ah 0.02 ~ 0.5;

Buuxiyaha aan dabiiciga ahayn 0.05 ~ 3;

Wakiilka nukliyeerka dabiiciga ah 0.01 ~ 0.2.

Isku-darka polypropylene iyadoo la adeegsanayo resin polypropylene, stabilizer thermal, stearic acid, cusbada birta ah, buuxinta organic iyo qadar yar oo ah wakiilka nucleating ayaa ahaa diyaarinta granulation isku dhafan, adkaanta sare, caabbinta kulaylka sare iyo faa'iidada jaban, tignoolajiyada diyaarinta waa mid fudud, resin polypropylene Isku-dhafkan waxaa loo isticmaali karaa baabuurta, qalabka guriga iyo guriga iyo goobaha kale.
