SPC ndiyo chidimbu cheStone Plastic Composites.Iyo huru yezvinyorwa ndeye polyvinyl chloride resin.Inogadzirwa neextruding muchina wakasanganiswa neT-mold kuburitsa SPC substrate, uchishandisa matatu kana mana roller calendering muchina kupisa uye laminate PVC kupfeka-resisting layer, PVC color film uye SPC substrate zvichiteerana.Iyo nzira yekugadzira haishandisi glue zvachose.

SPC pasi raw material:

PVC 50 KG

Calcium carbonate 150KG

Calcium zinc stabilizer 3.5-5KG

Kukuya hupfu (calcium zinc) 50

Stearic asidhi 0.8

ACR 1.2

PE wakisi 0.6

CPE 3

Impact modifier 2.5

Carbon dema 0.5

Pfungwa huru dzeRecipe

1.PVC resin: Kushandisa ethylene nzira shanu mhando resin, simba kuoma zviri nani, kuchengetedzwa kwezvakatipoteredza.

2. Fineness ye calcium powder: Nemhaka yokuti chikamu chekuwedzera chakakura, chinokanganisa zvakananga mutengo wefomati, machining performance uye kupera uye kubvarura kwescrew barrel uye chigadzirwa chekugadzira, saka coarse calcium powder haigoni kusarudzwa, uye kunaka kwekarusiyamu poda inobatsira 400-800 mesh.

3. Mukati nekunze lubrication: Tichifunga nezvezvinhu zviri mu extruder yakakwirira tembiricha yekugara nguva yakareba, pamwe nekuita kwezvinhu uye kubvisa simba zvinhu, zvinokurudzirwa kushandisa yakakwira-inoshanda wakisi kudzora huwandu hudiki hwekushandisa, uye kushandiswa. yewakisi yakasiyana kusangana nekutanga uye yepakati - uye yenguva refu yekuzora zvinodiwa.

4.ACR: Pamusana pehuwandu hwehuwandu hwe calcium powder muSPC pasi, zvinoda plasticizing zvakakwirira.Pamusoro pekutonga kweiyo screw type uye kugadzirisa tekinoroji, zvinowedzerwa zvinofanirwa kuwedzerwa kubatsira plasticizing, uye kuve nechokwadi chekuti kunyungudika kune rimwe simba, uye kune imwe ductility mukuita calendering.

5. Toughening agent: Pauriri haidi chete kuderera kwe shrinkage rate, kusimba kwakanaka, asi inodawo imwe kuoma, kuoma uye kusimba kunoda kuenzana, kuve nechokwadi kusimba kwekiyi, kwete kupfava pakupisa kwepamusoro, uye kuchengetedza kumwe kuomarara pane tembiricha yakaderera.Iko kuoma kweCPE kwakanaka, asi kuwedzerwa kwenhamba yakawanda yemakopi kunoderedza kusimba kwePVC, kunyorova kwekushisa kweVica, uye kunotungamirira kune yakakura shrinkage rate.

6. Anti shrinkage mumiririri: compress the particle gap pakati pePVC zvinhu kuderedza shrinkage inokonzerwa nekushisa.

7, PE wakisi haisi yekuzora chete, uye ine mhedzisiro yekuparadzira, asi huwandu hwehuwandu hwekufurira kwemukati nekunze kwekuzora chiyero uye kunyungudutsa simba shanduko uye kuwedzera shrinkage yezvigadzirwa uye kuderedza simba rekubvisa, zvigadzirwa zvinova brittle.

8. Kudzokorodza: ​​edza kushandisa kugadzirwa kwekambani kudzokorodza uye mushure mekugadzirisa zvinhu zvekudzokorodza.

Ongorora: Yakachena, kwete kunyorova, batch kupwanya musanganiswa mushure mekugaya.Kunyanya, iyo yakadzokororwa zvinhu zveiyo yakachekwa groove inofanirwa kusanganiswa nehupfu hwekukuya muchiyero kuita yakavharwa yekudzoka zvinhu kutenderera.Izvo zvinodikanwa kugadzirisa maitiro ekugadzirisa sampuli kana huwandu hwekudyisa huchichinja zvakanyanya.Iyo nzira yekugadzira haishandisi glue zvachose.
