Umenzi ochwephesha woomatshini be-thermoforming.
Zeziphi izinto zePlasitiki eziLungileyo koomatshini abaNcinci abaNcinci abaThermoforming?
I-PVC, i-PET, i-PS, njengezinto eziluhlaza, ukutshintsha isikhunta kumatshini omnye kwi-lids yokuvelisa, iikhava, iitreyi, iipleyiti, iibhokisi, ukutya kunye neetreyi zonyango, njl.
Ipolyvinyl chloride (PVC)
I-Polyvinyl chloride, efinyeziweyo njenge-PVC, i-polymer eyenziwe yi-polymerization yamahhala ye-vinyl chloride monomer phantsi kwesenzo se-initiators ezifana ne-peroxides kunye ne-azo compounds, okanye ngokukhanya kokukhanya kunye nobushushu. Kubonakala njengomgubo omhlophe, ongeyotyhefu kwaye ongenavumba, kunye nobunzima be-molecular ngokuqhelekileyo ukusuka kwi-50,000 ukuya kwi-110,000 (ye-PVC ecocekileyo eveliswe kwimizi-mveliso). Ubuninzi bayo obusondeleyo buyi-1.35-1.45, ebonisa ukufunxa kwamanzi aphantsi kunye nokungena kwegesi (i-PVC ecocekileyo). Ayinyibiliki emanzini, kwipetroli, etywaleni, okanye kwi-vinyl chloride, kodwa inokunyibilika kwiiketoni, ii-esters, kunye ne-chlorinated hydrocarbon solvents. I-Polyvinyl chloride (i-PVC) iqhayisa ngokuxhathisa imichiza eyomeleleyo kwaye isisithinteli sombane esilungileyo; nangona kunjalo, ayinyangeki kakhulu. Kubalulekile ukuqaphela ukuba le mpahla ayizinzile xa ibonakaliswe kwi-oxygen kunye nobushushu, okwenza kube lula ukuthotywa.
Ngokudibanisa impembelelo modifiers kunye organic tin stabilizers kwi PVC, kulandele ukuxuba, plasticizing, kunye calendering, amaphepha transparent aveliswa. Ngokusebenzisa i-thermoforming, inokuthi yenziwe ibe zizikhongozeli ezicacileyo ezinodonga olucekethekileyo okanye zisetyenziselwe ukupakisha okwenziwe ngevacuum, isebenza njengeyona nto ibalaseleyo yokupakisha kunye nezinto zokuhombisa.
uyakufumana iPVC ekujikelezileyo kuba iyakwazi ukumelana nedangatye kwaye ibuphatha kakuhle ubushushu. Intloko ekhawulezayo: ngelixa ime yomelele ngokuchasene neekhemikhali ezininzi kwaye iyisigqubuthelo sombane esikhulu, inokuba brittle kwaye ayithathi mpembelelo inzima kakuhle. Ikwanobuntununtunu ekuvezweni kwexesha elide kwioksijini kunye nobushushu obuphezulu, obunokubangela ukuba yophule.
Polyethylene Terephthalate (PET)
I-PET lihashe lomsebenzi weeplastiki ezicacileyo, ezomeleleyo. Ukuba uke wabamba ibhotile yesoda okanye isitya sokutya esicacileyo, uyazi ukuba i-PET ivakalelwa njani: icwecwe, icwebezelayo, kwaye inzima. Yimathiriyeli egqwesa ngokwenene ekupakisheni.
Nantsi into eyenza kube luncedo kakhulu:
Amandla kunye nokucaca: Yomelele ngokumangalisayo kwaye ayivaleki-i-3 ukuya ku-5 amaxesha amaninzi kunempembelelo kunezinye iifilimu zeplastiki-kwaye iyasonga ngaphandle kokwenza buthathaka. Ngaphezu koko, icace gca ngokwendalo kunye neglosi entle eyenza iimveliso zibukeke zintle.
Isithintelo esikhulu: Senza umsebenzi ogqwesileyo wokugcina ioksijini, ukufuma, kunye nevumba ngaphandle, yiyo loo nto igcina ukutya kwakho kutsha kunye nesoda yakho ifizzy.
Iqinile kwaye ikhuselekile: Ibamba amaqondo obushushu ukusuka kwi-70 ° C yonke indlela ukuya kuma-65 ° C ngaphandle kokuphulukana namandla ayo. Ikwayakwazi ukumelana neeoli kunye namafutha, kwaye ayinayo ityhefu ngokupheleleyo kwaye ikhuselekile kuqhagamshelwano lokutya.
Ikhusela: Ithintela ukukhanya kwe-ultraviolet, ikhusela okungaphakathi ekonakalisweni lilanga.
Ipolystyrene (PS)
I-Polystyrene yaziwa kakhulu ngeendlela ezimbini: njengeplastiki eqinile, ecacileyo (njengee-CD iimeko) okanye njenge-insulation enegwebu (Styrofoam™). Yimathiriyeli ekhaphukhaphu, eguquguqukayo exatyiswe ukucaca kwayo kunye neempawu zokugquma.
I-Polystyrene ayinambala kwaye iyabonakala, iyamkela ngokulula i-pigmentation, kwaye inoxinaniso oluphantsi oluthelekiswa ne-polypropylene (PP) kunye ne-polyethylene (PE). Ibonisa iimpawu zombane ezibalaseleyo, ngokukodwa iimpawu ezibalaseleyo ze-high-frequency, okwesibini kuphela kwi-PTFE kunye ne-PPO. Ukongezelela, ukuzinza kwayo kokukhanya kukwesibini kuphela kwi-polymethyl methacrylate (PMMA), ngelixa ukuxhathisa kwayo kwimitha yokukhanya kunamandla kuzo zonke iiplastiki. Olona phawu lubalulekileyo lwe-polystyrene luzinzo olugqwesileyo lwe-thermal kunye nokuhamba ngexesha lokunyibilika, okwenza kube lula ukusetyenzwa kunye nokulungele ukuveliswa kobuninzi. Ibonisa ukucutheka okuphantsi kokubumba kunye nokuzinza okuhle kwe-dimensional kwiimveliso ezibunjiweyo.
Ukujonga indlela esi sixhobo sinokubunjwa ngayo ngokufanelekileyo kwiimveliso zokugqibela, siyakumema ukuba ube namava ethu amaNcinci amaNcinci we-Multi-station Thermoforming Machine . Sisisombululo esincinci, esinexabiso eliphantsi lokuqalisa ngokukhawuleza owakho umgca wemveliso osebenzayo.
