I-PVC ekhazimlisiweyo yophahla lweTile yoMda we-Extrusion

Iithayile ezikhazimlisiweyo zePVC luhlobo olutsha lwezinto zokuhombisa uphahla, ikakhulu ezisetyenziselwa uphahla lweevillas, iipaviyoni, iindawo zokungcebeleka kunye nezinye izakhiwo. Isebenzisa i-polyvinyl chloride (i-PVC) njengeyona nto iphambili kwaye ixelisa imilo kunye nembonakalo yethayile ye-ceramic ekhazimlisiweyo ngenkqubo yokubumba i-extrusion, kodwa ikwanenzuzo yokukhanya, ukungangeni kwamanzi, ukuvutha komlilo, ukuxhathisa ukubola, ukumelana nokuguga, ukufakwa okulula, njl.

Ithayile ekhazimlisiweyo yePVC

Imveliso yeethayile ezikhazimlisiweyo zePVC ikakhulu ithatha iteknoloji yokubumba i-extrusion. Itekhnoloji ephambili yayo ilele koku:

1. Iteknoloji ye-Co extrusion: Uninzi lweethayile ezikhazimlisiweyo zePVC zisebenzisa iteknoloji ye-Co extrusion.

· Umaleko ophezulu (umaleko womphezulu): Ukongeza isixa esikhulu se-anti UV agents (UV), i-titanium dioxide (TiO2), kunye ne-pigments ecebileyo yokuqinisekisa ukuxhathisa imozulu kunye nokuqina kombala weethayile, ngaphandle kokubuna iminyaka engaphezu kweshumi.

·Umaleko ongezantsi (umaleko ongezantsi): ubukhulu becala owenziwe ngePVC kunye ne-calcium carbonate (CaCO3) ukuqinisekisa ukomelela, ukuqina, kunye noncedo lweendleko zeethayile.

2. Ukubunjwa kwe-vacuum: I-embryo ye-tile etyhidiweyo ekhutshwe kwi-mold ngokukhawuleza ingena kwi-vacuum shaping table, kunye ne-vacuum adsorption kunye nokupholisa kwamanzi okupholisa, iphinda iphinde ngokuchanekileyo i-concave convex imilo kunye neenkcukacha zetayile ekhazimlayo, kwaye ngokukhawuleza iqinise kwaye iyenze.

Umgca wemveliso wethayile okhazimlisiweyo wePVC ozenzekela ngokugqibeleleyo ubandakanya ezi nkqubo zilandelayo:

1. Inkqubo yokuxuba

·Isantya esiphezulu imixube eshushu kunye nokubanda:

·Le yimfuneko efunekayo ukuze kusetyenzwe ngePVC. Yongeza i-resin ye-PVC, isizinzi, isilungisi, isithambiso sangaphakathi, isithambiso sangaphandle, isihluzi (i-CaCO3), i-pigment kunye nezinye izongezo ngokomlinganiselo wefomula kwisantya esiphezulu somxube oshushu{2}, kwaye uxube ngokupheleleyo, ungene kwaye uzifake kwiplastikhi kubushushu obuphezulu (malunga ne-120 degree).

·Yifake ngoko nangoko kwisixube esibandayo kwaye ukhawuleze uyipholise ukuya kutsho kuma-40-50 ukunqanda ukudityaniswa kwezinto kunye nokuthotywa, kwaye ufumane umgubo oxubeneyo owomileyo.

2. Inkqubo ye-Extrusion

·Iwele eliQonxileyo{0}}i-screw extruder:

·Le "yintliziyo" yomgca wemveliso kunye nokhetho olufanelekileyo lokulungisa umgubo wePVC. Iwele eli-conical-isikrufu sinamandla okutya okuqinileyo, ukufudumeza okuphakathi kokucheba, kunye nesiphumo esihle sokuxuba kunye neplastiki.

·Co extrusion host: isetyenziselwa ukukhupha imathiriyeli engundoqo (isiseko esisezantsi).

·Umatshini oncedisayo we-Co extrusion: ngokuqhelekileyo isikrufu esinye esincinci se-extruder, eyilelwe ngokukodwa ukukhupha imathiriyeli yomaleko womphezulu.

·Co extrusion mold:

·Lo ngundoqo wobugcisa. Kukho idizayini echanekileyo yoyilo lomjelo ngaphakathi kobumba, obunokudibanisa ngokuchanekileyo imijelo emibini yezinto ezityhidiweyo ezivela kumatshini oyintloko (izinto ezisezantsi) kunye nomatshini oncedisayo (indwangu) kwintloko yokubumba, kwaye wenze iimilo ezithile zeetayile ezikhazimlayo (ezifana ne-waveform, S{1}}shape, njl.).

·Umathiriyeli: Intsimbi yodidi oluphezulu, enemijelo yangaphakathi ekhazimliswe kakhulu egugileyo{0}}ekwaziyo ukumelana nokudleka{1}}iyakwazi ukudleka.

3. Ukubunjwa kwevacuum kunye nenkqubo yokupholisa

·Itheyibhile yokumisa ivacuum:

·Esi sisitshixo sokubumba. Ubushushu obuphezulu-ithayile ye-embryo ethambileyo ekhutshiweyo emlonyeni wokungunda ifunxwa ngoko nangoko kwimilo yokuqala yokufa yetafile yokumila.

·Kukho amanzi okupholisa ngaphakathi kumngundo wokubumba, kwaye iindonga zokungunda eziphezulu nezisezantsi ziphindaphinda ngokuchanekileyo imilo yokugqibela yeethayile ezikhazimlisiweyo. Uxinzelelo olubi oluveliswa yimpompo ye-vacuum ibambelela ngokuqinileyo kwi-embryo ye-mold eludongeni lwe-mold cavity, ipholisa ngokukhawuleza kwaye iqiniswe kwimilo echanekileyo.

·Idla ngokuqulunqwa ngamacandelo amaninzi (afana namacandelo ama-4-6) ebhokisi yokulungisa ivacuum, enobude obufikelela kwi-6-8 yeemitha, ukuqinisekisa ukuba iithayile zipholile ngokupheleleyo kwaye zimile.

·Itanki yamanzi okupholisa:

·Emva kokumila kwangaphambili kwitafile yokumila, iithayile zingena kwitanki yamanzi okupholisa ukuze ziphole okokugqibela, ziwavumela ukuba afikelele ngokupheleleyo kwiqondo lobushushu begumbi.

4. Inkqubo yokutsala kunye nokusika

·Itrektara yodidi lweCrawler:

·Nikeza eyomeleleyo, ezinzileyo, kwaye nkqu nokutsala ukutsala iithayile ngokutyibilikayo ngaphandle komngundo, ukoyisa ukuxhathisa okukhulu kwetafile yokufunxa. I-Crawler traction inokukhusela ngcono imilo yeethayile kwaye uphephe ukutyumza.

·isarha yokusikwa okuzenzekelayo:

·Esi sisitshixo sokufikelela kwi-automation. Isixhobo sokusika sivumelanisa (iingoma) kunye nesantya sokuhamba kweetayile ngokusebenzisa i-photoelectric okanye i-encoder signals, kwaye emva koko yenza ukusika. Emva kokuba ukusika kugqityiwe, ibuyela kwindawo yayo yokuqala.

·Ubude bokusika bunokusetwa ngokuchanekileyo ukuqinisekisa ukuba ubude bethayile nganye buhambelana kwaye ukusika kuyagudiswa kwaye kulinganayo.

5. Inkqubo encedisayo

·Isixokelelwano sokufunxa: ibonelela ngeqondo lokufunxa elizinzileyo nelineleyo letafile yokumila.

·Inkqubo yokujikeleziswa kwamanzi: ibonelela ngamanzi okupholisa kwii-extruders, izinto zokubumba, iitafile zokubumba, kunye namatanki okupholisa amanzi.

·Inkqubo yokulawula ubushushu: Lawula ngokuchanekileyo ubushushu becandelo ngalinye le-extruder kunye ne-co extrusion mold.

·Inkqubo yokulawula ye-PLC: idibanisa zonke iimotor, ubushushu, ivacuum, ukutsala, kunye nokusika, edla ngokuxhotyiswa -nobungakanani besikrini esichukumisayo esilungele ukusetwa kweparameter kunye nokubeka iliso.

I-PVC resin+ izongezo (izinzisi, izithambiso, njl.) kunye nokupakishwa → iithayile ezimenyezisiweyo zePVC ezigqityiweyo

1. Ifomula ingundoqo: ifomyula egqwesileyo kunye nokumelana nemozulu yimfuneko ukuze kuveliswe{1}}iithayile ezikhazimlisiweyo ezikumgangatho ophezulu, ngakumbi ukhetho lwe-UV resistant agents kunye ne-pigments kwi-surface layer formula.

2. Itheyibhile yokubumba kunye neyokubumba ingundoqo: inqanaba loyilo kunye nokuchaneka kwenkqubo yale nkqubo ichaza ngokuthe ngqo ukubonakala, ukuchaneka kwe-dimensional, kunye nokuzinza kwemveliso yeetayili. Ukubumba okulungileyo kunokukhutshwa okufanayo kunye nokubunjwa okulula.

3. I-teknoloji ye-Co extrusion: Qinisekisa ukuba ilaphu kunye ne-substrate ziboshwe ngokuqinileyo ngaphandle kwe-delamination, kwaye ukuba ubukhulu belaphu bufana kwaye umbala uhambelana.

4. Khetha umboneleli onamava: Uyilo lweemolds zetayile ezikhazimlayo zifuna amava, kunye nokulungiswa kwezixhobo (ezifana nokufanisa idigri ye-vacuum, ubushushu becandelo ngalinye, kunye nesantya sokuhamba) kubaluleke kakhulu. Qinisekisa ukuba ukhetha abavelisi bezixhobo abanamatyala aqolileyo.

5. Cacisa ukubekwa kwemveliso: Ngaphambi kokuthenga, kuyimfuneko ukugqiba iinkcukacha (ububanzi, ubude, ubude, ubukhulu), imveliso, kunye nenqanaba lomgangatho (njengokuzaliswa kwezinto eziphathekayo) kwimveliso ejoliswe kuyo, ukwenzela ukuba umthengisi wezixhobo unokubonelela ngeemodeli ezifanelekileyo (ezifana nobukhulu be-extruder) kunye nokubunjwa.

1. Umgca wemveliso usetyenziselwa ukuveliswa kweetayile zePVC + ASA / PMMA ezikhazimlisiweyo, kunye neenkcukacha ezibandakanya ububanzi be-720mm, 930mm, 1100mm, ubukhulu be-2mm, 2.5mm, 3mm;

2. Umaleko we-PVC uveliswa yi-SJZ80/156 i-conical twin - i-screw extruder, ngelixa i-ASA okanye i-PMMA layer ikhutshwe ngu-SJ50 enye ye-screw co-umatshini we-extrusion, Isixhobo sikwabandakanya T-i-molds ezibunjiweyo, oomatshini bokubumba, oomatshini bokusika kunye ne-stacking racks;

3. Ukubonelela ngesikhokelo malunga nemathiriyeli ekrwada yefomula nokuthengwa kwemathiriyeli ekrwada;

4. Yila iimveliso ezichubekileyo ezineendleko eziphantsi zemveliso kunye{1}}nomgangatho ophezulu wokusebenza.

Iifayile ezishisayo: i-pvc ekhazimlisiweyo yophahla lwetayile yomgca we-extrusion, iChina i-pvc ekhazimlisiweyo yophahla lwetayile abavelisi, ababoneleli, umzi-mveliso
