1. Engasindi

I-Plastiki yizinto ezilula ezinobukhulu obuyi-0.90-2.2.Ngokusobala, ingabe amapulasitiki angantanta emanzini?Ikakhulukazi amapulasitiki anegwebu, ngenxa yama-micropores angaphakathi, ukuthungwa kulula, futhi ukuminyana kwesihlobo ku-0.01 kuphela.Lesi sici sivumela amapulasitiki ukuthi asetshenziswe ekukhiqizeni imikhiqizo edinga ukukhanyiswa kwesisindo sabo.

2. Ukuzinza kwamakhemikhali okuhle kakhulu

Amapulasitiki amaningi anokumelana nokugqwala okuhle kumakhemikhali anjengama-asidi nama-alkali.Ikakhulukazi, i-polytetrafluoroethylene (F4), eyaziwa ngokuthi iNkosi yePlastiki, izinzile kakhulu kumakhemikhali kunegolide, futhi ngeke yonakale ngisho noma ibiliswe ku-“aqua regia” amahora angaphezu kweshumi.Ngenxa yokuthi i-F4 inokuqina okuhle kwamakhemikhali, iyinto efanelekile ukumelana nokugqwala.Isibonelo, i-F4 ingasetshenziswa njengempahla yokudlulisa amapayipi oketshezi abolayo nabonayo.

3. Izakhiwo ezinhle kakhulu zokuvala ugesi

Amapulasitiki avamile angama-conductor ampofu kagesi, futhi ukumelana kwawo kwendawo kanye nokumelana nevolumu kukhulu kakhulu, okungafinyelela ku-109 kuya ku-1018 ohms ngezinombolo.I-voltage yokuhlukana inkulu, futhi inani le-tangent lokulahlekelwa kwe-dielectric lincane.Ngakho-ke, amapulasitiki anezinhlobonhlobo zezicelo embonini yezogesi kanye nemboni yemishini.Okufana nezintambo zokulawula ezifakwe epulasitiki.

4. I-conductor ye-thermal embi, enciphisa umsindo kanye nomphumela wokumunca ukushaqeka

Ngokuvamile, ukushintshwa okushisayo kwepulasitiki kuphansi, kulingana ne-1/75-1/225 yensimbi, kanye nama-micropores epulasitiki egwebu.

Iqukethe igesi, ene-insulation engcono yokushisa, i-sound insulation kanye nokumelana nokushaqeka.Isibonelo, i-thermal conductivity ye-polyvinyl chloride (PVC) iyi-1/357 kuphela yensimbi kanye ne-1/1250 ye-aluminium.Mayelana nomthamo wokushisa oshisayo, amafasitela epulasitiki engilazi eyodwa aphakeme ngo-40% kunamafasitela engilazi eyodwa ye-aluminium, futhi amafasitela anengilazi ephindwe kabili aphezulu ngo-50%.Ngemva kokuba iwindi lepulasitiki selihlanganiswe nengilazi engenalutho, lingasetshenziswa ezindaweni zokuhlala, ezakhiweni zamahhovisi, ezigcemeni, nasemahhotela, ukonga ukushisa ebusika nokonga izindleko zokupholisa umoya ehlobo, futhi izinzuzo zisobala kakhulu.

5. Ukusatshalaliswa okubanzi kwamandla emishini namandla athile aphezulu

Amanye amapulasitiki aqinile njengetshe nensimbi, kanti amanye athambile njengephepha nesikhumba.Ngokombono wezakhiwo zemishini ezinjengokuqina, amandla aqinile, ubude, namandla omthelela wamapulasitiki, anobubanzi bokusabalalisa okubanzi futhi anezinketho eziningi ongazisebenzisa.Ngenxa ye-gravity encane ethile namandla aphezulu epulasitiki, inamandla athile aphezulu.Uma kuqhathaniswa nezinye izinto, amapulasitiki nawo anokusilela okusobala, njengokuvutha, ukuqina okuphakeme kunezinsimbi, ukumelana nokuguga okubi, nokumelana nokushisa.

Ngakho-ke, imikhiqizo yethu yepulasitiki isebenzisa izinto zepulasitiki ngokusho kwemvelo yomkhiqizo
Ngokwesibonelo:ukhezoimikhiqizo ngokuyisisekelo yibanga lokudla i-PP kanye nebanga lezokwelapha le-PP.
Iumjovokubanga lezokwelapha PP, kanyetest tubeinebanga lezokwelapha le-PP noma i-PS.Iibhodlela lokufuthangokuyisisekelo inhlanganisela ye-PET ne-PP.

Ngobaisikhuntaizinto esizisebenzisayo ziyinsimbi enhle kakhulu yokubunjwa, njenge-718. Izinga lemikhiqizo yepulasitiki eyenziwe yinhle kakhulu.Sinesipiliyoni seminyaka engu-13 somlando kule ndawo, sisebenza kahle kakhulu
