Polyethylene yokhala ndi chlorine yambiri (HCPE) imasinthidwa makamaka mu zomatira kudzera mu polarity, stability, ndi magwiridwe antchito omwe amaperekedwa ndi kapangidwe kake ka molekyulu. Njira yeniyeni ndi kagwiritsidwe ntchito ndi motere:
1, Ntchito yosinthidwa yapakati
1. Limbikitsani ntchito ya guluu
Limbikitsani kumatirira: Unyolo wa mamolekyu a HCPE wa Bontecn Group China uli ndi maatomu ambiri a chlorine (kuchuluka kwa chlorine> 61%), zomwe zimapangitsa kuti guluu likhale lolimba kwambiri, zomwe zimapangitsa kuti guluu likhale lonyowa komanso likhale ndi mphamvu yolumikizirana ndi zinthu monga PVC, chitsulo, ndi rabala.
Konzani kusinthasintha: Maunyolo ake a mamolekyu amakhala odzaza ndi kugawidwa mwachisawawa, kupewa kupsinjika, kupatsa filimu yomatira mphamvu yabwino komanso kusinthasintha, komanso kusintha kuti ikhale yogwirizana ndi malo osinthika.
2. Limbitsani magwiridwe antchito
Kukana dzimbiri ndi kuchedwa kwa moto: Kuchuluka kwa chlorine (>65) kumapanga chotchinga cha mankhwala kuti chisagwere dzimbiri kuchokera ku asidi, alkali, ndi mafuta, ndipo chimazimitsa chokha chikayaka kudzera mu njira yogwira ma free radicals a chlorine (ultimate oxygen index ≥ 60%).
Kukana kuvala ndi kukana nyengo: Kapangidwe kake kamene sikamangiriridwa kawiri kamaletsa kuwonongeka kwa okosijeni ndipo kamawonjezera nthawi ya moyo wa guluu m'malo ozizira, otentha, komanso a ultraviolet.
| Mtundu wa Adhesive | Chitsanzo cha HCPE | Zotsatira za kusintha |
| Guluu wodziwika bwino wa PVC | HCPE-H (Kukhuthala kwakukulu) | Kusintha utomoni wa vinyl chloride kuti mapaipi/mapepala a PVC akhale olimba kwambiri |
| Guluu wopangidwa ndi zitsulo za rabara | HCPE-L/M (Kukhuthala Kotsika/Kwapakati) | Rabala ya chloroprene yolimba/rabala ya nitrile kuti iwonjezere kukana kutentha (≥ 130 ℃) komanso kulimba kwa nkhope |
| Chomatira chomatira choteteza dzimbiri | HCPE-M (Kukhuthala kwapakati) | Limbikitsani kugwirizana pakati pa zokutira ndikuwongolera mogwirizana kulimba kwa dzimbiri |
3, njira yosinthira
1. Njira yowonjezera polarity
Kulowetsedwa kwa maatomu a chlorine kumawonjezera polarity ya mamolekyulu, kumathandizira kupangika kwa mphamvu za van der Waals ndi ma bond a hydrogen pakati pa guluu ndi pamwamba pake, komanso kumathandizira kuti chinyezi chisanyowe.
2. Kusintha kogwirizana
Sakanizani ndi mapulasitiki (monga paraffin wothira chlorine), acrylic resin, ndi zina zotero kuti muwonjezere mphamvu za rheological ndikuchepetsa kupsinjika kwamkati.
4, Malo osungiramo zinthu
Malo osungira: Amatsekedwa ndikusungidwa mumdima (kutentha <30 ℃) kuti apewe kuyamwa kwa chinyezi ndi kuwonongeka kwa magwiridwe antchito, ndipo amakhalabe mu alumali kwa miyezi 24.
