1. Codsiga iyo Diyaarinta Kooban:
Maaddada gaarka ah ee daahan polypropylene waxaa inta badan loo isticmaalaa daahan ee bac-xidhka polypropylene iyo maro tolan. Dahaarka ka dib, bacaha tolmada leh ee ka samaysan dahaarka ayaa si toos ah loo isticmaali karaa iyada oo aan la daboolin bacaha polyene. xoogga iyo guud ahaan wax qabadka bacda dhogorta ah ayaa la wanaajiyey sababtoo ah filimka wareegga polypropylene ayaa si toos ah loogu dhejiyaa bacda dharka, isticmaalka ayaa ku habboon, kharashka wax soo saarka ayaa sidoo kale la dhimay.

Wakaalladda Qalabka Dhismaha ee Qaranka (National Building Materials Bureau) waxay aasaastay ereyada & lt;1997>No.079 bishii Noofambar 1997, iyadoo qeexaysa in bacaha tolmada leh loo isticmaalo baakadaha sibidhka iyo alaabta kale. Isla mar ahaantaana, horumarinta warshadaha baakadaha gudaha, qiyaasta isticmaalka iyo qiyaasta darajada rinjiga PP ayaa si tartiib tartiib ah u kordhay. Soo saaraha caagga ah ee asalka ah ayaa soo iibsaday khadka wax soo saarka ee bacaha iyo bacaha isku dhafan, oo laga beddelay bacdii asalka ahayd ee PE ee gudaha PP bac laba-in-hal bac ah iyo saddex-in-hal warqad bac isku dhafan, iyo baahida suuqa ee fasalka PP ayaa maalinba maalinta ka dambaysa sii kordhaya. Heerka rinjiga guriga ee PP sahayda ayaa ciriiri ah.
Marka la eego kor ku xusan, waxaan ku salaysan T30S guud iyo 2401 (MFR = 2 ~ 4 g / 10min) oo si guul leh u horumariyo qalab gaar ah oo darajada daahan (MFR = 20 ~ 32 min, xoog adkaysiga 24.0 MPa) iyada oo hoos u dhac la xakameeyey ka dib markii la isku daro.

Inta lagu guda jiro geedi socodka horumarinta, dhowr tijaabo ayaa lagu sameeyay xulashada jaangooyooyinka miisaanka molecular iyo waxyaabo kale oo dheeraad ah, isku dhafka iyo caagagga alaabta ceeriin iyo hababka habka la xiriira. Ka dib markii la hagaajiyay baarista, habka qaabeynta iyo soo saarista ee daboolka PP ayaa la go'aamiyay. samee khad wax soo saar ballaaran. Natiijooyin lagu qanco ayaa lagu helay codsiyo badan, kuwaas oo had iyo jeer ka tarjumaya tayada xasilloon ee alaabta, dhalaalid wanaagsan oo dhalaalaysa, samaynta filim isku mid ah, hoos u dhac hooseeya, xoogga diirka sare iyo dhejinta sare. 2. faa'iidooyinka dhaqaale ee la saadaaliyay:

Qiimaha alaabta gaarka ah halkii tan oo daahan ah ayaa ku saabsan 2,000 yuan ka sarreeya qiimaha alaabta ceeriin. Ka dib markii laga jaray qalabyada, shaqada, tamarta, qiimo dhimista farsamada iyo kharashyada kale ee 150 yuan, faa'iidada saafiga ah ee tan ee alaabta gaarka ah waa 1500 yuan. Wax-soo-saarka sanadlaha ah ee khadka-soo-saarka (oo lagu xisaabiyo extruder oo leh dhexroorka 65) waa 350-450 tan, canshuurta saafiga ah ee sanadlaha ah waxay gaari kartaa in ka badan 500000 yuan. Haddii aad isticmaasho fur-fure weyn, wax soo saarku wuu sarreeyaa. Waqtigan xaadirka ah, Shiinuhu wuxuu leeyahay in ka badan 1000 warshado bac oo waaweyn, tuulooyin iyo magaalooyin iyo ganacsiyo gaar loo leeyahay oo aan la tirin karin. Mashruucu wuxuu leeyahay rajooyin ballaaran.
Marka labaad, tignoolajiyada diyaarinta ee qaboojinta polypropylene masterbatch polypropylene qaboojinta masterbatch waa polypropylene-ku salaysan masterbatch, inta badan loo isticmaalo si loo yareeyo heerkulka ee daadi polypropylene iyo alaabta caaga ah ee processing, gaar ahaan in polypropylene miiqdaan saamayn aad u fiican, laakiin sidoo kale loo isticmaalo in wax soo saarka ee afuufaan polypropylene. filim, bacaha dunta, monofilament, alaabta qaabaynta irbado ayaa sidoo kale helay natiijooyin wanaagsan.
Tusmada waxqabadka ugu muhiimsan: ku dar 1 ~ 5% qaboojinta masterbatch in resin polypropylene for processing; waxay gaari kartaa dhibcooyinka soo socda: dhammaan darajooyinka xabagta polypropylene waxay soo saari karaan tayada sare ee C wareeg ah fiber denier ganaax. Heerkulka wareegga iyo balaastigga ayaa laga dhimi karaa 20 ° C ilaa 50 ° C; hagaajinta tayada fiber polypropylene iyo alaabta caaga ah; hagaajinta wax-soo-saarka; lana yareeyo wasakhowga deegaanka.

Baaxadda arjiga: miiqinta polypropylene, afuufista filimka polypropylene, bacaha tolka leh ee polypropylene, monofilament
