Magolovesi a PVCndi magolovesi oonda opangidwa ndi kusakaniza utomoni wa polyvinyl chloride paste, plasticizer, stabilizer ndi viscosity-reduction agent mu pulasitiki ya phala, yomwe imayikidwa, zouma ndi pulasitiki kupyolera mu njirayi.
Zofunikira za magolovesi a PVC
Magolovesi a PVCamapangidwa ndi polyvinyl chloride kudzera mwapadera.Magolovesi alibe allergen, opanda ufa, otsika fumbi m'badwo, otsika ayoni okhutira, opanda plasticizers, esters, silikoni mafuta ndi zigawo zina, ndi mphamvu kukana mankhwala, kusinthasintha bwino ndi kukhudza, zosavuta ndi omasuka kuvala, ndi anti- static properties, ndipo ingagwiritsidwe ntchito m'malo opanda fumbi.
Mbali: 1. Kugonjetsedwa ndi ofooka zidulo ndi zamchere;2. Zochepa za ionic;3. Kusinthasintha kwabwino ndi kukhudza;4. Oyenera kupanga njira zopangira monga semiconductors, makhiristo amadzimadzi ndi ma hard disks.
Magolovesi a PVC amagwiritsa ntchito mitundu yosiyanasiyana
1, zinthu zapamwamba za PVC.2, Kugwiritsiridwa ntchito kwa manja onse awiri, kugubuduza m'mphepete mwa dzanja lotsegula.3, Njira yapadera yochizira, palibe kuyabwa pakhungu, ziwengo.4, M'badwo wochepa wa fumbi ndi ma ionic, ma CD opanda fumbi.5, Yogwiritsidwa ntchito kuyeretsa chipinda / chipinda choyera / msonkhano woyeretsera / semiconductor, kupanga hard disk, optics mwatsatanetsatane, zamagetsi zamagetsi, LCD / DVD liquid crystal kupanga, mankhwala achilengedwe, zida zolondola, kusindikiza kwa PCB ndi mafakitale ena.Magolovesi a PVC amagwiritsidwa ntchito kwambiri poteteza ntchito komanso ukhondo wapakhomo poyang'anira zaumoyo, mafakitale a chakudya, makampani opanga mankhwala, zamagetsi, makampani opanga mankhwala, makampani opanga utoto ndi zokutira, makampani osindikizira ndi opaka utoto, ulimi, nkhalango, kuweta nyama ndi mafakitale ena.
Magolovesi a PVC formula
PVC ufa 100 magawo
DOP 78-82 magawo
TXIB 10-15 magawo
Calcium ndi nthaka stabilizer 2-2.5 mbali
Pigment 0.01-2 magawo
Epoxy soya mafuta 2-2.5 magawo

Filler Kukwanira kokwanira
Onjezani mitundu yonse ya zopangira molingana, yambitsani kamodzi kuti mufooke ndikuyimitsa, fyuluta, gwedezani kawiri ndikupukuta.
Njira yopanga magolovesi a PVC
Pambuyo pa kusefa, kupukuta ndi kuyimirira, kusakaniza kumapopera mu thanki ya impregnation ya mzere wopanga.Pansi pa zinthu yachibadwa kupanga, dzanja amaumba pa mzere basi kulowa impregnation thanki, ndi zisamere pachakudya ndi emulsion Ufumuyo amatuluka mu thanki impregnation nayenso, atembenuza mosalekeza pa ulendo kuti emulsion padziko dzanja zisamere pachakudya yunifolomu. , ndi kupanga emulsion owonjezera kugwa pansi.Madzi akudontha amabwerera ku thanki yoyimiritsa kudzera mu thanki yotolera.Pambuyo kudontha emulsion owonjezera, nkhungu m'manja chimayenda ndi mzere kupanga mu uvuni, kumene kutentha ng'anjo amalamulidwa pa 230-250 digiri Celsius ndi emulsion pa dzanja kukhudza kuphika ndi kupangidwa pansi chikhalidwe ichi.Zoumba za manja kuchokera ku uvuni zimakhazikika mwachibadwa, milomo imakulungidwa ndi ufa, ndiyeno magolovesi amachotsedwa pamanja pazitsulo zamanja, zomwe zimayenda mosalekeza ku thanki ya impregnation.Magolovesi a PVC osatulutsidwa amapangidwa ndi ufa kenako amasungidwa ngati zinthu zomalizidwa.
Njira yamagetsi ya PVC yaufa
Kuthira → kusakaniza → kusefa → static defoaming → kumata → kudontha → kuphika → kuziziritsa → kugudubuza milomo → kuviika ufa (ufa wa chimanga) → kugwetsa → kuchotsa ufa → kuyang'anira khalidwe → kuyika → kusunga
Njira yoyendetsera magolovu a PVC opanda ufa
Kusakaniza→Kusonkhezera→Kusefa→Kuimirira ndi kuchotsa thovu→Zomata →Kugwetsa→Kuphika→Kuzizilitsa→Kuthira madzi aPU→Kuphika→Kuziziritsa→Kugudubuza milomo→Kuboola →Kuona ubwino→Kuyika →Kusunga
