1. Chidule cha Ntchito ndi Kukonzekera:
Zapadera za ❖ kuyanika polypropylene zimagwiritsa ntchito ❖ kuyanika polypropylene thumba thumba ndi nsalu nsalu. Pambuyo pakupaka, matumba opangidwa ndi zokutira amatha kugwiritsidwa ntchito mwachindunji popanda matumba a polyene. mphamvu ndi ntchito yonse ya chikwama cholukidwa bwino chifukwa filimu yozungulira ya polypropylene imakutidwa mwachindunji pathumba loluka, ndipo kugwiritsa ntchito ndikosavuta, komanso mtengo wopanga nawonso wachepetsedwa.

Boma la State Building Materials Agency (National Building Materials Bureau) linakhazikitsa mawu akuti & lt;1997>No.079 mu November 1997, ponena kuti matumba oluka opangidwa ndi laminated ayenera kugwiritsidwa ntchito kulongedza simenti ndi zinthu zina. Pa nthawi yomweyo, ndi chitukuko cha mafakitale zoweta ma CD, ntchito osiyanasiyana ndi mlingo wa utoto kalasi PP pang'onopang'ono kukodzedwa. Wopanga pulasitiki woyambirira adagula mzere wopangira matumba apulasitiki ndi nsalu zophatikizika, zomwe zidasinthidwa kuchokera ku thumba lamkati la PE lamkati la PP thumba loluka kukhala thumba lawiri-mu-limodzi ndi thumba la pulasitiki lopangidwa ndi mapepala atatu, komanso kufunikira kwa msika. PP ikuwonjezeka tsiku ndi tsiku. Kupezeka kwa utoto wapanyumba PP ndikokwanira.
kupatsidwa pamwambapa, ife zochokera T30S ambiri ndi 2401 (MFR = 2 ~ 4 g / 10min) ndi bwino kupanga zipangizo zapadera za ❖ kuyanika kalasi (MFR = 20 ~ 32 min, kumangika mphamvu 24.0 MPa) kupyolera ankalamulira kuwonongeka pambuyo kusakaniza.

Panthawi yachitukuko, zoyeserera zingapo zidachitika pakusankha zowongolera zolemetsa ndi zina zowonjezera, kusanganikirana ndi pulasitiki yazinthu zopangira ndi magawo okhudzana ndi njira. Pambuyo poyang'anitsitsa bwino, mapangidwe ndi kupanga zokutira za PP zinatsimikiziridwa. kupanga mzere wopangira misa. zotsatira zokhutiritsa zapezedwa kupyolera mu ntchito zambiri, zomwe nthawi zonse zimasonyeza khalidwe lokhazikika la mankhwala, kusungunuka kwamadzimadzi kwabwino, mawonekedwe a filimu yofananira, kutsika kochepa, mphamvu ya peel ndi kumatirira kwambiri. 2. Mapindu azachuma omwe akuyembekezeredwa:

Mtengo wa zipangizo zapadera pa toni ya zokutira ndi pafupifupi 2,000 yuan kuposa mtengo wa zipangizo. Pambuyo pochotsa zida, ntchito, zothandizira, kutsika kwamitengo yamakina ndi ndalama zina za 150 yuan, phindu lokwanira pa tani ya zida zapadera ndi 1500 yuan. The pachaka linanena bungwe mzere kupanga (mawerengedwe ndi extruder ndi wononga m'mimba mwake 65) ndi matani 350-450, ndi msonkho wapachaka ukonde akhoza kufika yuan oposa 500000. ngati mugwiritsa ntchito screw extruder yayikulu, zokolola zake ndizambiri. Pakadali pano, China ili ndi mafakitale akuluakulu opitilira 1000, midzi ndi matauni ndi mabizinesi apayekha osawerengeka. Ntchitoyi ili ndi chiyembekezo chachikulu.
Chachiwiri, kukonzekera luso la polypropylene kuzirala masterbatch polypropylene kuzirala masterbatch ndi polypropylene ofotokoza masterbatch, makamaka ntchito kuchepetsa kutentha kwa polypropylene kupota ndi mankhwala pulasitiki mu processing, makamaka polypropylene kupota tingati kwambiri, komanso ntchito yopanga polypropylene kuwomba. filimu, matumba nsalu, monofilament, jekeseni akamaumba mankhwala alandiranso zotsatira zabwino.
main performance index: kuwonjezera 1 ~ 5% kuzirala masterbatch kuti polypropylene utomoni kuti processing; amatha kukwaniritsa mfundo zotsatirazi: magiredi onse a polypropylene resin amatha kutulutsa utomoni wapamwamba kwambiri wa C wozungulira wabwino wokana. Kutentha kozungulira ndi kukonza pulasitiki kumatha kuchepetsedwa kuchoka pa 20 ° C mpaka 50 ° C; kusintha ubwino wa polypropylene CHIKWANGWANI ndi mankhwala pulasitiki; kupititsa patsogolo kupanga bwino; ndi kuchepetsa kuwononga chilengedwe.

Kuchuluka kwa ntchito: polypropylene spinning, polypropylene film kuwomba, polypropylene matumba nsalu, monofilament
