1. Ilula

Iplastiki yinto ekhaphukhaphu enobunzima obuphakathi kwe-0.90-2.2. Ngokucacileyo, ngaba iiplastiki zingadada emanzini? Ingakumbi iiplastiki ezine-foam, ngenxa yee-micropores ezingaphakathi, ubume bayo bukhaphukhaphu, kwaye ubunzima obuphakathi buyi-0.01 kuphela. Olu phawu luvumela iiplastiki ukuba zisetyenziswe ekuveliseni iimveliso ezifuna ukukhanya kobunzima bazo.

2. Uzinzo oluhle kakhulu lweekhemikhali

Uninzi lweeplastiki zinokumelana kakuhle nokugqwala kwiikhemikhali ezifana nee-asidi kunye nee-alkali. Ngokukodwa, i-polytetrafluoroethylene (F4), eyaziwa ngokuba yiKumkani yeePlastics, izinzile ngakumbi kwiikhemikhali kunegolide, kwaye ayizukuwohloka nokuba ibilisiwe kwi-"aqua regia" kangangeeyure ezingaphezu kweshumi. Ngenxa yokuba i-F4 inozinzo oluhle kakhulu lweekhemikhali, sisixhobo esifanelekileyo sokumelana nokugqwala. Umzekelo, i-F4 ingasetyenziswa njengesixhobo sokuhambisa imibhobho yolwelo egqwalayo nekrakra.

3. Iipropati ezibalaseleyo zokukhusela umbane

Iiplastiki eziqhelekileyo azikhokeli kakuhle zombane, kwaye ukumelana kwazo nomphezulu kunye nokumelana nomthamo kukhulu kakhulu, okunokufikelela kwi-109 ukuya kwi-1018 ohms ngamanani. I-voltage yokuqhekeka inkulu, kwaye ixabiso le-dielectric loss tangent lincinci. Ke ngoko, iiplastiki zinoluhlu olubanzi lwezicelo kushishino lwe-elektroniki kunye noomatshini. Ezifana neentambo zokulawula ezigqunyiweyo zeplastiki.

4. Umqhubi we-thermal ongekho mgangathweni, onefuthe lokunciphisa ingxolo kunye nokufunxwa komothuko

Ngokubanzi, ukuhanjiswa kobushushu beplastiki kuphantsi kakhulu, kulingana ne-1/75-1/225 yentsimbi, kunye nee-micropores zeplastiki ye-foam.

Iqulethe igesi, enobushushu obungcono, ubushushu obuphezulu kunye nokumelana nokutshayiswa. Umzekelo, ubushushu obuphezulu be-polyvinyl chloride (PVC) buyi-1/357 yentsimbi kunye ne-1/1250 ye-aluminium kuphela. Ngokuphathelele umthamo wobushushu obuphezulu, iifestile zeplastiki zeglasi enye ziphezulu ngama-40% kuneefestile ze-aluminium zeglasi enye, kwaye iifestile zeglasi ezimbini ziphezulu ngama-50%. Emva kokuba ifestile yeplastiki idityaniswe neglasi engenanto, ingasetyenziswa kwiindawo zokuhlala, izakhiwo zeeofisi, iiwadi, kunye neehotele, igcina ukufudumeza ebusika kwaye igcina iindleko zomoya opholileyo ehlotyeni, kwaye iingenelo zicacile kakhulu.

5. Ukusasazwa ngokubanzi kwamandla oomatshini kunye namandla athile aphezulu

Ezinye iiplastiki ziqinile njengelitye nentsimbi, kwaye ezinye zithambile njengephepha nesikhumba. Ngokwembono yeempawu zoomatshini ezifana nokuqina, amandla okutsalwa, ukunwebeka, kunye namandla okuchaphazeleka kweeplastiki, zinoluhlu olubanzi lokusasazwa kwaye zinezinto ezininzi onokuzisebenzisa. Ngenxa yobunzima obuncinci kunye namandla aphezulu eplastiki, inamandla aphezulu. Xa kuthelekiswa nezinye izinto, iiplastiki nazo zineziphene ezicacileyo, ezifana nokutsha, ukuqina okuphezulu kuneentsimbi, ukumelana nokuguga okubi, kunye nokumelana nobushushu.

Ngoko ke, iimveliso zethu zeplastiki zisebenzisa izinto zeplastiki ngokwendalo yemveliso.
Umzekelo:icepheiimveliso ngokusisiseko ze-PP yenqanaba lokutya kunye ne-PP yenqanaba lezonyango.
Iisirinjiyi-PP yenqanaba lezonyango, kwayeityubhu yokuvavanyaune-PP okanye i-PS yenqanaba lezonyango.ibhotile yokutshizangokusisiseko yindibaniselwano ye-PET kunye ne-PP.

KubaisikhuntaIzinto esizisebenzisayo zilungile kakhulu kwi-mold steel, njenge-718. Umgangatho weemveliso zeplastiki ezenziweyo ulungile kakhulu. Sineminyaka eli-13 yamava embali kweli candelo, sinobungcali kakhulu.
