application

PVC hose kugadzira maitiro:

Kusanganisa → kukanya → kuwedzeredza granulation → extrusion kuumba → kukwenya → kukochekera → kurongedza → kuongorora kunaka → chigadzirwa chapera

1. Kukanya zvinhu

Ese marudzi emidziyo yakabikwa anoyerwa nemazvo uye anoiswa mukneader mune imwe hurongwa.Kudyisa kutevedzana: PVC resin, plasticizer, stabilizer, lubricant.Kana tembiricha yasvika 100 ~ 110 ℃, zvinhu zvinogona kuburitswa.

2.extrusion granulation

Iyi nzira yekudzora tembiricha, iyo yepamusoro-soro tembiricha yemidziyo inofanirwa kudzorwa pakakwirira pane kunyunguduka tembiricha yezvinhu, yakaderera pane tembiricha yekuumba extrusion, ndiko kuti, pakati pe155 ~ 160 ℃.Granulation inofanirwa kuzadzisa chinangwa chekusanganisa kwakazara uye yekutanga plasticization.

Tembiricha yenzvimbo imwe neimwe yegranulator yakaita seinotevera:

Nzvimbo ye80 ~ 90 ℃;Nzvimbo ye130 ~ 140 ℃;Nzvimbo nhatu 140 ~ 150 ℃;Kubva 150 ~ 160 ℃.

3. extrusion chubhu kugadzira

Tembiricha ye extrusion chubhu inogadzira yakakwira zvishoma.Kazhinji, kujeka kwepombi kune hukama nekushisa kwekugadzira.Mune imwe tembiricha yemhando, iyo yakakwirira tembiricha yakajeka yakanaka, uye zvinopesana.Panguva imwecheteyo, kumhanyisa kumhanya uye kutonhora kumhanya kuchakanganisa kujeka kwepombi.Kumhanya kwekufambisa kwakakura zvishoma, kukurumidza kutonhora kunokurumidza, uye kujeka kwepombi kuri nani.Kudhonza kumhanya kunowanzo 10% ~ 15% nekukurumidza kupfuura extrusion kumhanya.Kutonhodzwa kwepombi inoonekera inopfapfaidzwa nemvura inotonhora pakufa kwemhuno yozotonhodzwa mutangi remvura.

Tembiricha yenzvimbo yega yega ye extrusion molding ndeiyi inotevera:

Zoni 1:90 ℃;Zone mbiri 140 madhigirii 5 ℃;Nzvimbo nhatu 160 madhigirii 5 ℃;Mazoni mana 170 madhigirii 5 ℃.

4. PVC hose extrusion precautions:

1. zvakananga nehupfu extrusion molding, tembiricha ye extruder inenge 5 ℃ yakaderera pane ine granular material.

2. Pamusoro peiyo dhayamita diki (φ60mm pazasi) yechubhu isina kutonhora kutonhora haidi kupeperetswa mumhepo yakamanikidzwa, iyo yakakura dhayamita yechubhu isina kutonhora inotonhorera inofanira kupeperetswa muchubhu yakamanikidzwa mhepo, kuitira kuti ive nechokwadi. kunyatsoita uye kugadzikana kwechubhu dhayamita saizi.Teerera kune yakagadzikana kumanikidzwa kwemhepo yakamanikidzwa.

3. Chenjerera kugadzikana kwekumhanya kwekufambisa uye udzivise kushanduka kwepombi dhayamita kana kukora kwemadziro kunokonzerwa nekusagadzikana kwekudhonza.

4. Kana muchina wacho wakavharwa kwenguva yakareba, unofanira kubviswa uye kucheneswa kuti udzivise matambudziko ekuora.
