Mafirimu ePVC anoshandiswa zvakanyanya mukurongedza chikafu, zvekurima, uye kurongedza maindasitiri. Extrusion uye calendering ndiyo miviri mikuru yekugadzira maitiro.
Extrusion: Kubudirira Kunosangana Nemutengo Kubatsira
Extrusion nzvimbo dzakatenderedza screw extruder. Iyo compact midziyo inochengetedza nzvimbo uye iri nyore kuisa uye kugadzirisa. Mushure mekusanganisa zvinhu maererano nemaitiro, vanokurumidza kupinda muextruder. Sezvo screw inotenderera nekumhanya kwakanyanya, zvinhu zvinokurumidza kuisirwa purasitiki neshear force uye kunyatsodziya. Zvadaro, ivo vanowedzerwa muchimiro chekutanga chefirimu kuburikidza nemusoro wakagadzirirwa kufa, uye vanozopedzisira vatonhodzwa uye vakaumbwa neinotonhora rollers uye mhete yemhepo. Nzira yacho inoenderera mberi nepamusoro-soro.
Ukobvu hwefirimu hunotangira pa0.01mm kusvika 2mm, hunoenderana nezvinodiwa zvakasiyana. Kunyangwe yunifomu shoma mukukora kupfuura mafirimu ekare, inoshanda kune zvigadzirwa zvine yakaderera precision zvinodiwa. Kushandisa zvinhu zvakadzokororwa kunoderedza mari. Nekudyara kwemidziyo yakaderera uye kushandiswa kwesimba, inopa purofiti yakakura. Nekudaro, mafirimu eextrusion anonyanya kushandiswa mukurima uye kurongedza maindasitiri, senge mafirimu egreenhouse uye mafirimu anotakura zvinhu.
Calendering: Zvakafanana nePamusoro-kuguma Hunhu
Iyo midziyo yecalendering nzira inoumbwa neakawanda epamusoro-chaiyo yekudziya rollers. Anowanzoita matatu-roll, mana-roll kana mashanu-roll makarenda, uye ma roller anofanirwa kunyatsogadziriswa kuti ave nechokwadi chekuti oparesheni yakanyatso. Zvishandiso zvinotanga zvakasanganiswa ne-high-speed kneader, zvino pinda musanganisi wemukati wepurasitiki yakadzika, uye mushure mekumanikidzwa mumapepa neguyo rakashama, vanopinda mucalender. Mukati mekarenda, mapepa acho anonyatso kubudiswa uye akatambanudzwa neakawanda ekupisa rollers. Nekudzora tembiricha uye kupatsanurwa kwema rollers, kutsauka kwemufirimu kunogona kudzikamiswa mukati me ± 0.005mm, uye kupfava kwepamusoro kwakakwira.
Mafirimu eCalender PVC ane ukobvu hwakafanana, akaenzana mamechani zvivakwa, akanakisa optical zvimiro, uye yakakwirira pachena. Mukurongedza chikafu, vanoratidza chikafu uye vanovimbisa kuchengeteka. Mune yepamusoro-yekupedzisira zvinhu zvezuva nezuva uye zvemagetsi zvigadzirwa kurongedza, yavo yepamusoro mhando inovaita sarudzo yepamusoro.
Mukugadzirwa kwemafirimu ePVC, ingave iri calendering process kana extrusion process,PVC stabilizerskuita basa rinokosha.Sravana Sameeralu Serial 4th TopJoy Chemical'smvura barium-zincuyecalcium-zinc stabilizersinhibit kushatiswa kwePVC pakupisa kwakanyanya, kuve nechokwadi kugadzikana kwezvinhu, kupararira zvakanaka muPVC system, uye kuwedzera kugadzirwa kwehunyanzvi. Kugamuchirwa kuti utitane nesu chero nguva uye kutarisira kuenderera mberi nekubatana newe!
