SPC masitepe ndi mankhwala extrudes PVC m'munsi zakuthupi ndi extruder pamodzi ndi T woboola pakati kufa, ndipo amagwiritsa ntchito mpukutu atatu kapena anayi mpukutu calender kulekanitsa PVC kuvala zosagwira wosanjikiza, PVC mtundu filimu ndi PVC m'munsi zakuthupi, ndi kutentha, laminate ndi emboss mankhwala nthawi imodzi., Njirayi ndi yophweka, kukwanira kumatsirizidwa ndi kutentha, palibe guluu lomwe limafunikira.
Njira zopangira masitepe a SPC:
1. Kudyetsa: PVC utomoni ufa, kashiamu ufa, plasticizer, stabilizer ndi zipangizo zina zimadyetsedwa molingana ndi dongosolo metering pa doko chakudya, ndi kudyetsa ndi manja kapena vacuum kudyetsa.
2. Kusakaniza: metering basi malinga ndi chiŵerengero cha zipangizo, zopangira kudzera metering dongosolo kulowa mkulu ndi otsika liwiro chosakanizira → mkulu liwiro chosakanizira kwa kusakaniza otentha (kutentha kusakaniza kutentha kutentha: 125 °C, ntchito ndi kusakaniza mitundu yonse ya zipangizo mofanana ndi kuchotsa chinyezi mu zipangizo ) → lowetsani zosakaniza zozizira (ziziritsani zinthuzo kuti muteteze kusakanikirana ndi kusinthika, kutentha kosakanizika kozizira: 55°C.) → sakanizani zipangizo zofanana pozizirira.
3. Extrusion akamaumba: Tumizani zosakaniza zopangira mu extruder, ndi ntchito kutentha kwake ndi mkulu kuthamanga boma extrude kudzera gawo lapansi nkhungu.Njira yotulutsa imatenga pafupifupi mphindi 2, kutentha kuli pafupifupi 180-220 ° C, ndipo mafuta otengera kutentha amagwiritsidwa ntchito.Chipangizochi chikuwotcha.
4. Kuphimba filimu ndi kalendala: Pepala la pansi la PVC lotulutsidwa pansi limakanizidwa kukhala mawonekedwe ophatikizika okhala ndi ma roll-roll kapena asanu-roll calenders, wosanjikiza wosavala ndi filimu yamtundu wa PVC.Imatengera Kutentha kwanthawi imodzi, lamination ndi embossing.Njirayi ndi yosavuta komanso yosavuta kuyika.Imamalizidwa ndi kutentha, pogwiritsa ntchito chowongolera kutentha kwa kutentha kwa mafuta, pogwiritsa ntchito mafuta otengera kutentha ngati sing'anga yotumizira kutentha kuti isunge kutentha kotentha kwa 140 ° C.
5. Kudula ndi kudula: kudula ndi makina odulira pamzere wa msonkhano.
6. UV wodzigudubuza: Chovala chodzigudubuza utoto wa UV wopangidwa ndi madzi pamwamba pa miyala-pulasitiki pansi, kutentha ndi kuchiritsa kupeza SPC mwala-pulasitiki pansi theka-womaliza mankhwala, UV wodzigudubuza ❖ kutentha: 80-120 ° C;Kuzizira kozizira: 10°C
4. Kucheka ndi kulowetsa + kulongedza: kudula → kudula, kudula, kupukuta → kuyang'ana → kuyika.
